View movies and TV Shows on 3D Displays

Human eyes are capable of viewing 3D images, and when people see these 3D images and films of the screen, they have the feeling that they are considering the real world on the screen. Many computer monitors are now available that display 3D images. Let us know about 3D graphics and 3D displays

3D Displays and 3D Graphics

3D graphics is not a new concept as many types of games and other virtual programs are being used for the past many years. 3D graphics are three-dimensional images that can be easily viewed on a 2D display. It is similar to view programs on a television screen.

3D displays are designed in such a way that people can have the perception of 3D images and graphics. To do this, the show is developed in such a way that each eye looks at the pictures with different views and let the brain interpret the image as a 3D image. The display will still be two-dimensional, but the film will be three-dimensional.

Types of 3D Displays

There are many types of 3D displays, which are discussed here.

3D Display with Shutter Technology

It is the most common form of 3D visualization. In this type of show, the images are altered with the help of LCD glasses that are synchronized with the display. These glasses alternate two images between the eyes. This technology is being used in computers for many years with the help of some specialized hardware.

LCD Displays

Individual glasses are not used in this type of display. This display is manufactured by using the parallax barrier, which is a particular type of filter used in LCD film. This helps in transferring lights at different angles. The result is that images shift slightly between two eyes. The disadvantage of this display is that 3D models can be formed on small screens and nit the big ones.

Volumetric Displays

The latest technology has been used in this display, but it has not still been applied in consumer goods. In this technology, there is a series of rotating or laser LEDs that represent images in a light which has the capability of filling up a three-dimensional space. One of the significant disadvantages of this technology is that ample space is needed for the image to be displayed. Lack of color is another disadvantage, and also, this technology is very costly.

Virtual Reality Goggles

The latest trend in viewing 3D images and motion pictures is the usage of virtual reality goggles. This technology is still under development has been very much different from other displays, whether 2D or 3D. Users have to wear these goggles, and each eye will see the image separately, and the 3D model will be generated. The main disadvantage is that it results in nausea and motion sickness. Another problem with this technology is its price, which is very high.

Benefits of 3D Displays

3D technology is best for usage in the field of entertainment and science. The technology has already added to the theaters to display 3D motion pictures. The main of the theater owners is to force people to come and watch the movies in the theaters. This option will increase the revenue of the theaters. Another place where the 3D graphics is being used is computer games. These games are very addictive, and people do not want to leave the game until they finish it to the last stage.

Wrapping Up

3D technology is still under development, and users will have better experience in the future while watching movies or playing games. Some of the techniques used currently are giving good results in increasing the revenue while some are very expensive.

Touch your screen to perform all tasks

Touchscreen technology can be found everywhere, like mobile phones, tablets, laptops, printers, and many others. The enhancement in graphical user interface and the development in touchscreen technology is growing, and that is the reason that touchscreen can be found everywhere.  Let us know more things about touchscreen technology.

What is the touchscreen?

A touchscreen is said to be an input device with which users can do all the work by just touching the screen. There are many devices which may or may not have an electronic display, but touchscreen technology can be installed anywhere.

Touchscreen Components

There are three components in a touchscreen, which include a touch sensor, controller, and software. The touch sensor has the job of measuring the contact between the finger and the touchscreen. The measurement can be done at any point in time.

The controller has the job of capturing the touch information provided by the touch sensor. This information is provided to the processor. The software works with the touch sensor and controller to respond to the touch done by a user.

Types of touchscreen technology

There are five types of the touchscreen, and all of them are based upon the touch sensor used in them. These types are as follows.

  • Resistive Touch Screen Technology
  • Capacitive Touch Screen Technology
  • Infrared Touch Screen Technology
  • Acoustic Wave Touch Screen Technology
  • Near Field Imaging Touch Screen Technology

Advantages and disadvantages

Here are the details of each of these technologies along with their advantages and disadvantages:

Resistive Touchscreen Technology

This technology is considered as the commonest one as it has a glass panel having a coating of two electrically conductive thin metallic layers. These metallic layers are separated by a narrow gap. The gap consists of separator dots. When the outer surface s touched, it brings the two conductive layers into contact. The panel allows the voltage to pass and metal contact divides the voltage. This change in energy decides the shift in touch.

Capacitive Touchscreen Technology

Another most popular touchscreen technology is a capacitive touchscreen. In this type of touchscreen, there is a glass panel on which there is a thin transparent charge storing electrode layer. In this type of touchscreen, the electrical conductivity of humans is necessary. As soon as a user touches the screen, a reaction occurs between the electricity in the human body and the electrode layer. The changes in capacitance are measured by the sensors located at the four corners of the screen. There are two types of capacitive touchscreen technologies, which are as follows.

  • Surface Capacitive Touch Screen Technology
  • Projected Capacitive Touch Screen Technology

Infrared Touchscreen Technology

In this touchscreen technology, infrared light is used, which causes interruption on the screen. The panel of the screen has infrared LEDs and phototransistors, and they are positioned opposite to each other. An invisible infrared grid of infrared light is created due to this setup. As soon as a finger is placed ion the screen, the interruption in light occurs, which determines the point of contact.

Acoustic Wave Touch Screen Technology

This is an advanced touchscreen technology in which sound waves are sent through the glass panels. Piezoelectric transducers and receivers are available on the sides of the board. As soon as the screen receives a touch, a portion of the sound is absorbed and sent to the transducer, which identifies the point of contact.

There are two types of acoustic touchscreen technologies, which are as follows.

  • Surface Acoustic Wave Touch Screen Technology
  • Guided Acoustic Wave Touch Screen Technology

Wrapping Up

These are the types of technologies available in various devices, and when the users touch the screen, it is responded by the technology used in the touchscreen. The technique can be found on many devices like laptop, mobiles, tablets, etc.

Perform necessary transaction through Automated Teller Machine

Automated teller machine helps the customers to do some of the banking transactions without the help of any banking executive. There are two types of devices. One is that which allows users to withdraw cash and receive a receipt containing account balance. Another machine is a complex one, which people can use to deposit some money, perform credit card payments, and also get a mini report of their account.

This electronic machine helps the people to complete underlying bank transactions, and they have to use a particular type of plastic card in which their personal information is encoded on a magnetic strip. The code on the piece is transferred to the computer in the bank with the help of modem. As soon as the card is inserted into the machine, it processes the account transaction. The device was invented in 1960 by John Shepherd-Barron. Let us talk about the components of the machine.

Input devices

Input devices are used to read data and send it to the server for further processing. The input devices used in the machine are as follows:

Card Reader

The card reader presenting the computer reads the card when a person inserts the card. This input device identifies the account number of the user with the help of the magnetic strip present in the map. The card reader reads the information present on the card and passes the data to the server. The host processor receives the data from the cardholders in this way.

Keypad

After the user inserts the card, and the data is read, the next step is to use the keyboard to provide further data, and the most important is the personal identification number or PIN. After inputting the PIN, he will get a list of transactions like cash withdrawal, balance inquiry, etc.

Output devices

Output devices are used to write the data and display it. The output devices used in these machines are discussed here.

Speaker

When the user presses a key or enters any information, he gets a message to do the next step through the speaker. If he comes wrong information, the speaker tells of opening the news again.

Display Screen

The screen displays the information about the transaction along with the steps of each of the sale. For example, if a user wants to withdraw money, he gets the option of the type of account he has to select, and then he has to enter the amount.

Receipt Printer

The printer provides detail about the transaction that the user has performed. If he has withdrawn money, he receives a printout stating the amount withdrawn and the balance left in the account. If he has made balance inquiry, he gets the information about the balance in the receipt.

Cash Dispenser

Cash dispenser is a central system from where the cash amount comes out, and the user has to collect the cash from here. The cash dispenser first counts the amount entered by the user, and then it dispenses the liquid. There is an RTC device in the machine that keeps the records of all the transactions.

Types of ATMs

There are two types of ATMs, which are discussed here.

Leased Line ATMs

These machines are directly connected to host processors with the help of four-wire point to point telephone lines. The cost of operating this machine is very high.

Dial-up ATMs

This machine is connected to the host processor with the help of phone line and modem. The installation and operating cost of these machines is meager.

Wrapping Up

In this article, we have discussed automated teller machines, its components, and types. These machines are beneficial and have reduced the burden of bank employees and are also comfortable for users.

Get rid of wires through Wireless Technology

There era many wired devices that still exist, and people sue them, but they sometimes become very irritating as wires become cluttered, and this even lead to damaging or breaking of the cables. So wireless technology was invented. The technology was started in the 19th century, and now it has been developed to a much higher level. The technology is still under development. People are using the technology to communicate, connect to the internet, and many others. Here we will discuss various types of wireless technologies.

Satellite Communication

This is wireless communication, which is spread all over the world. People can connect even if they are separated by a long distance. In this technology, a signal is sent to the satellite, which provides energy to the message and sends it back to the antenna receiver. The two main components of this technology are the space segment and the ground segment. The equipment used in the ground segment can be mobile transmission or a receiver, and the space segment includes the satellite.

Infrared Communication

This system uses infrared radiation to communicate with various devices. The wavelength of this radiation is more significant than that of red light. The technology is used in TV remote control, security control, and other short-range communication. The main components required for this type of transmission include a photo LED transmitter and photodiode receptor. The task of the LED transmitter is to transmit the light, and the receptor stores it.

Broadcast Radio

This is the first wireless technology and is still in use nowadays. There are multichannel radios, which users can use to speak over shirt distances. The maritime radios were used by the sailors to communicate. Data can be easily shared with Ham radio. This technology is also used for digital communication over a radio frequency spectrum.

The sound is broadcasted by an audio broadcasting service in the form of radio waves through the air. There is a transmitter, which is used to transmit data from the radio to the radio receiving antenna. Simulcast, syndication, or both formats are used to broadcast the data.

Microwave Communication

This type of communication uses radio waves whose wavelengths are measured in centimeters. There are two methods in which data can be transmitted. The first one is a satellite, and the second is the terrestrial method.

In the satellite method, the data is transmitted to the satellite whose distance is 22300 miles. The data are sent and received to and from the stations — the frequency of sending and receiving data ranges between 11 GHz to 14 GHz. The speed of transmission of information ranges between 1 Mbps and 10 Mbps.

In the terrestrial method, there are two towers, and there should be no obstacle between them. The frequency of data transmission is 4 GHz to 6 GHz, and the data transmission speed is 1 Mbps to 10 Mbps. The signals are disrupted by rains, and this is the main disadvantage of this type of communication.

Wi-Fi

Wi-Fi is a wireless technology, which comes with meager power. This technology can be used in laptops, mobiles, tablets, and other such devices. Users need to install a router for Wi-Fi communication. This technology is used in networking applications, which are protected by passwords.

Bluetooth Technology

Users can use this technology to connect various devices wirelessly with each other for communication. Information can be easily transmitted from one device to the other with the help of this technology.

Wrapping Up

These are wireless technology, which people can use for wireless communications. People will soon get rid of the cluttered wires because of this technology. The technology is still under development and has a good future.

Edit your pictures with Digital Cameras

Cameras have been used for many years. First reel cameras were used, and people were able to click only black and white images. Then cameras with colored lens came and in this case also, and reels were used. Then came the turn of digital cameras, and people can save the mages on their computers. Cameras also available in mobiles so now there is a need to use reels. People can save pictures on various devices like laptops or external hard drive. Here we will discuss different types of digital cameras.

DSLR Cameras

Digital Single Lens Reflex Cameras or DSLR Cameras are very popular and available in the market at a different price range. People can find many professionals with these cameras. The camera consists of a digital imaging sensor and a single-lens reflex camera. These cameras come with detachable lenses so users can change the glass based on the type of photography they have to do. The camera comes with the half-frame and full-frame options.

Mirrorless Cameras

DSLR cameras have an optical viewfinder, and if it is removed, t5he camera becomes the mirrorless camera. Removing the viewer will also reduce the weight of the camera a little. There are two types of mirrorless cameras, which include crop frame camera and a full-frame camera. These cameras also have the feature of the detachable lens, but the options of glass is very less as these cameras are new in the market.

Point and Shoot Cameras

These cameras are compact and are valuable for those people who often go for a picnic which their friends and families. The main aim of such people is to click the pictures and store it on various storage devices. The camera has a fixed lens and variable focal length. The pictures clicked by the camera are best for documentation.

Smartphone Cameras

Smartphones are coming with great cameras. They have rear, as well as front cameras and users, use to click pictures anywhere they like. The front camera is used for taking a selfie. The software included for the cameras help the users to get blur and other types of effects. People who used DSLR cameras are happy with smartphone cameras. The smartphone cameras have declined the usage f point and shoot cameras. Users can click pictures in raw format and can edit it later.

Bridge Cameras

These cameras have the position between DSLR and point and shoot cameras. They have a fixed lens and has the feature of covering the telephoto lens. People who like to visit wildlife sanctuaries or enjoy a picnic but cannot afford a DSLR camera can buy the bridge cameras. These cameras support war format, and users can edit the pictures with the help of editing software applications installed on smartphones or laptops.

Medium Format Cameras

Previously 120mm films were used in these cameras, but now the cameras have a digital lens.  The camera has a big sensor and is available at a higher price. These cameras are suitable for those people who want to have high-quality pictures and noise performance. S8ch cameras are ideal for those people who are in the fashion designing field.

Film Cameras

The film was installed in these cameras, but now digital camera lens has taken its place. Still, films are used in these cameras because of the ISOP part of the images. Users need to change the movie regularly for ISO images.

Wrapping Up

There are various types of digital cameras available, and people can purchase them from the market or websites. The camera with a low price can be useful for going to a picnic or visiting a wildlife sanctuary. Professional cameras are of high quality and are used to i different professions.

Update: This is actually a computer monitor and not a 3D TV. The new series 9 monitors will come in 23″ and 27″ and will include a built-in 3D emitter.

Samsung is showing their updated ‘9-series’ 3D TVs (this is Samsung’s high end TV series) – with a beautiful ‘curved design’:

We don’t have any technical details yet, we just know that it’s a LED-backlit LCD. The current C9000, however, is ultra-slim (.3 inch thick) and supports Full-HD at 240Hz. The TV has built-in Wi-Fi (with Internet-Apps support) and a touch-screen remote that can show live TV via Wi-Fi. So we can guess that the new 9-series will have all that, and more. As soon as we have more information we are going to post a super detailed review. In the meantime you can check our friends at HopsReview for more information and marketing reviews.

Samsung will also unveil new Series-7 3D TVs at CES. We’ll keep you updated!

AUO to mass produce 65″ 3D panels in 2H 2010

FPD China starts tomorrow, and AUO will exhibit new 3D display technologies. The first one is a 65″ full-HD 3D panel, that they will start mass producing in 2H 2010. This one uses polarized 3D glasses that only weigh 10 grams, costing around $3 per pair. If you already have glasses, you can easily clip polarized lenses onto the regular frame.

AUO will also exhibit glasses-free barrier and lenticular lens displays.

AUO will also show new e-paper displays and OLED prototypes.

Sony’s active-shutter 3D glasses are now shipping for $149

Sony’s active-shutter 3D glasses are now available for $149. The glasses offer about 100 hours between charges, and auto-standby to improve efficiency. You can use these with your your HX800 or HX909 TVs (or the LX900, which includes 2 pairs already). For the HX800/909, you’d also need the 3D sync transmitter (which costs $48). You also need a 3D-player (such as Sony’s 3D Blu-ray players).

Buy the Sony 3D glasses now for $149.

Samsung releases new 3D glasses

Samsung has released 3 new 3D glasses today. All of them are battery operated (active-shutter) and require a Samsung 3D-ready TV with an emitter (such as the LED-LCD C7000 or PNC8000 plasma) and a 3D Blu-ray player (such as Samsung’s BD-C6900 that’s shipping for $399.).

  • SSG-2100AB: the basic model, costs $149
  • SSG-2200AR: – these are more expensive at $199
  • SSG-2200KR: these ones are for kids, come in pink and blue and cost $179

Samsung SSG-2100AB

All of those glasses are now available for pre-order over at Amazon.com, we do not know when they’ll ship yet. Interestingly, Samsung’s 3D-starter-kit includes 2 pairs of the basic model 2100AB, and costs $350 – so it’s cheaper to just buy two pairs at $299 (although the starter-kit includes a 3D Blu-ray movie – monsters vs aliens).

New 3D poster technology coming soon

The Fraunhofer institute, University of Kiel and RealEyes is showing a new technology that enables 3D posters for large (up to 5 meters) outdoors advertisements. And these do not require any glasses.

The researchers say that the display are similar to the lenticular images we’ve seen on postcards. But instead of the grooved sheet with the image attached, the new posters use a lens array – 250,000 lenses, each 2 millimeters in diameter. The 3D image can be viewed from the other side of the street, and the image appearance changes with each step and adjusts to the visual angle.

They have already built a DIN-A0 (1 sq meter) poster prototype, and they say that commercialization of larger posters (3 to 5 sq meters) is possible during 2011.

3D POSTER

Today it  has been achieved and  it is being  commercialized  in Spain, such images with lenses of 1.25 mm or 20-inch lenses.Actually, this technology is not new, if it is true that recent times are getting an excellent quality,  almost, these days, it has gotten to produce  it  industrially  with a really very low cost.The optimal size at the moment is a traditional MUPI (1.2m. X 1.8m high).  It’s true you might get a panel of five meters cracked, but the problem lies in the placement of such portions in the same plane,   they must be perfectly flat  without any kind of inclination,  so  this would give us a picture also cracked.
