Sharp today announced that it has developed the world's first high-quality naked-eye 3D mobile touch screen (supporting 2D/3D conversion), which also paves the way for Nintendo's development of the naked-eye 3DS handheld program.
The newly developed naked eye 3D LCD screen mainly uses parallax barrier (parallaxbarrier) system to form a stereoscopic image, and then with the advantage of CG silicon liquid crystal processing technology, the brightness and color saturation of the LCD screen are very outstanding.
The CG silicon process reduces the width of the wiring inside the LCD panel, allowing for a much higher light transmission rate. Compared to Sharp's previously produced LCD panels, the new LCD screen doubles the brightness to 500 lumens; optimization of parallax barrier technology allows for further enhancement of light utilization, while reducing color crosstalk and providing higher color saturation.
And, while the naked eye 3D display supports touch functionality, the LCD module is the same thickness as a traditional 2D module. Supporting landscape and portrait 3D image viewing, the new display is considered ideal for use in mobile tools such as smartphones.
Sharp's display developed this time is 3.4 inches, supports 480 X 854 pixel resolution, and has a brightness of 500 lumens in 2D mode. 1000:1 contrast ratio is almost 10 times that of conventional 3D LCDs of the same type.
In addition, Sharp is also developing a non-touch-capable 3D LCD, and plans to begin mass production in the second half of fiscal 2010.
Parallax Barrier Technology:
This is the process of splitting two images at different angles at equal distances into vertical line strips, and then fusing the left and right images together in a staggered fashion using interlace. The even part of the fused image is the right image and the odd part is the left image. However, to achieve the stereoscopic effect, it is also necessary to add the grating stripes between the light-transmitting slit and the light-impermeable barrier vertically to the fusion graphic, and the width between the slit and the barrier needs to be consistent with the width of the left and right image cuts, and then utilize the barrier's masking effect to ensure that the image corresponds to the left and right eyes, and to form a stereoscopic sensation through the difference in the images that are seen by the two eyes.
CG silicon treatment process:
It is a liquid crystal screen technology, in the outdoor bright light, by manually switching off the backlight tube, the light through the polarizing plate projected by a continuous single crystalline silicon (Silicon) composed of reflective electrodes, when the reflection of the light out of the brighter, the more saturated the state of the color of the LCD panel, the more vibrant the picture we viewed. The brighter the reflected light, the higher the color saturation of the LCD panel, and the more vivid the picture we see. In March 2013, Hewlett-Packard announced that they have developed a new type of naked-eye 3D technology, which can be used to install on mobile devices. In the future, people will be able to view 3D images on their cell phones directly with their naked eyes.
The technology was developed in March 2013 by quantum scientist Dr. David Fattal, along with colleagues at the Hewlett-Packard Research Institute.
The researchers focused on developing a backlit display whose main components are light-emitting diodes (LEDs) and an ultra-thin waveguide structure, the latter of which controls electromagnetic waves in the spectrum and works mainly by interfering with the light to skew it so that the human eye can see the three-dimensional effect. The key to this technology is based on waveguide technology based on light-emitting diodes, which can produce a wide-angle combined projection view, whether it is a static or dynamic image, the user can see the full-color image from multiple angles, even if the device is tilted.
Professor Neil Dodgson of the University of Cambridge's Computer Laboratory commented on the invention, saying that it would be a very fascinating invention, but also a meticulous and long research process, with developers ensuring the quality of the product before it could be put on sale.

Things in the picture that can be protruding from outside the picture, can also be hidden in the picture. Colorful, layered, vivid, lifelike, is the true meaning of three-dimensional stereoscopic images. Naked eye stereoscopic image with its real and vivid expressive power, beautiful and elegant environment infectious force, strong shock of visual impact by the majority of consumers favor.

Advantage two Wide viewing distance, full-angle 3D display Advantage three Can be customized according to customer requirements Size size, appearance Product features Feature one Low power consumption, energy saving and environmental protection Feature two Stylish and exquisite appearance The light barrier 3D technology is implemented by using a switching LCD screen, polarizing film and polymer liquid crystal layer, and a series of vertical stripes oriented at 90 ° are created by using the liquid crystal layer and polarizing film. These stripes are tens of microns wide, and light passing through them creates a vertical pattern of thin bars called the "parallax barrier". This technology utilizes the parallax barrier placed between the backlight module and the LCD panel. In stereoscopic display mode, when the image that should be seen by the left eye is displayed on the LCD screen, the opaque stripes will block the right eye; similarly, when the image that should be seen by the right eye is displayed on the LCD screen, the opaque stripes will block the left eye, and the left eye and right eye will be separated from the visible image, so that the viewer can see the 3D image.
The advantage of this technology is that it is more cost-effective, and is used by the likes of Sharp's 3D cell phones and Nintendo's 3DS game console. However, the brightness of the screen with this technology is halved because the light is blocked, and the image resolution is halved. Column lens technology, also known as micro-column lens 3D technology, allows the image plane of the LCD screen to lie on the focal plane of the lens so that the pixels of the image under each column lens are divided into sub-pixels so that the lens projects each sub-pixel in a different direction. Thus both eyes see different subpixels when viewing the display from different angles.
Pillar lens technology doesn't affect the brightness of the screen as much as the light-barrier type, so it provides a better display than the latter. However, its resolution is reduced to several times the original image resolution depending on the number of column lens viewpoints. Since ultra-high-definition TV images are not widely available, plasma mirror 3D technology is not widely used. 3M's Directional Backlight 3D technology
Directional Backlight (Directional Backlight) 3D technology to put more effort is mainly 3M, Directional Backlight (Directional Backlight) 3D technology with two groups of LEDs, with a fast response LCD panel and drive method, so that 3D content in order (sequential) way into the viewer. sequential) way into the viewer's left and right eyes to swap images to produce parallax, thus allowing the human eye to feel the 3D three-dimensional effect. Not long ago, 3M has just demonstrated its successful development of 3D optical film, the product's interviews realize the need to wear 3D glasses, can be in the cell phone, game consoles and other handheld devices to display true three-dimensional stereoscopic images, greatly enhancing the communication and interaction based on mobile devices.
Advantages: resolution, light transmission can be guaranteed, will not affect the existing design architecture, 3D display effect is excellent.
Disadvantages: The technology is still under development and the product is not mature. Direct imaging technology refers to the designated images, graphics through the processing of digital media through the call it to move up, thus giving a 3D effect, can make the things to be conveyed more close to life, the performance of more real. This technology is mainly used in the current Internet promotion, that is, advertising. Typical of this year's League of Legends on the network of three naked eye 3D posters as well as Tsui Hark's 3D team in this year's movie poster called "step by step", which is also the first time that this technology is used in the domestic commercial aspects of a very good example, which contributes to China's naked eye 3D technology to enhance and progress. This technology can be attached to ordinary computers, digital advertising machines, LED displays and other digital equipment for display and dissemination.
Advantages: Effectively enhance the existing e-commerce products to promote the form of expression, more expressive of the authenticity of the product.
Disadvantages: the technology is still in development, the product has been more mature. In April 2009, the U.S. PureDepth announced the development of improved naked eye 3D technology - MLD (multi-layer display), this technology can be overlapped at certain intervals through the two LCD panels, to achieve in the case of not using special glasses, watch the text and drawings presented in 3D. This technology allows two LCD panels to be overlapped at regular intervals, enabling the viewing of text and pictures in 3D without the use of specialized glasses.
In addition, the domestic manufacturer Ouya Baolong's Bolod naked-eye 3D display has been developed to the fourth generation, the product also realize all the high-definition display. Of course, due to the non-market mainstream, for MLD technology and Bolod naked eye 3D display, we only do a simple understanding this time, do not do in-depth technical discussions.
