Sharp has developed a dark contrast as high as 100 million: 1 LCD contrast LCD Panel "million". Envisaged in the television studios, ob vans and filming the scene and light darker places, while also meeting the requirements of the business use high contrast. Volume production planned for 2006. The trial production of a 37-inch Panel, at a press conference and the exhibition. Number of pixels to 1920 × 1080, brightness 500cd/m2.
Dark contrast as high as 100 million: 1
By displaying the night publicity contrast high
The LCD Panel of the target market, and mainly uses a 20-inch CRT monitors. Sharp estimate, as the market for low-profile of increasingly high demands on the screen size larger monitor needs to be growing. "The market on a global scale to 200 billion yen per year. The future is expected to get all of that market share "(the company directors AVC LCD cause the Minister to water Island propagation of light).
By improving the level of liquid crystal cells reduce black
And ordinary monitor and TV sets, TV Studio and filming the scene using the primary display, to light a darker room use. Therefore, the need to address the issues and not because the screen surface reflection of contrast decrease, but display the original "black" and "white" contrast. Since almost all use LCD back lights, the key lies in improving the performance of LCD shutter, the Suppression of diffusion within, without sacrificing the "white" efforts to increase the brightness of the "black".
Shooting the scene very much hope that the transition from CRT to LCD
In order to enhance the dark contrast, sharp in reducing back lights leaked on increased research efforts. Through improvements polarizer, color filter and LCD units for construction, etc, "addresses become leaked photo of the back and the diffuse light polarizing issues" (water colour). Although you also need to address the issue of new materials and new production technologies, but it is understood that the use of an existing plant to produce. However, this does not disclose any technical details. In addition, as a contrast ratio of price to present back as a slightly lower light utilization.
As the LCD contrast, Korea LG Philips and Hitachi made according to the display of image signal to control the LED rear lights glow of technology. While the sharp technologies, "back to the original lamps adopt the same cold cathode fluorescent tube (CCFL), you must back lights for special treatment" (water colour).
TV and video filming of the monitor must support HD, have higher dark contrast
For more than 10 million: 1 art camera CCD speed
Basic performance improvement has ended will then compete in the sense of
"Realized in previous LCD Panel cannot experience the multi-faceted paint plants sense." The face on the LCD contrast million, is on the monitor picture critic Ma bin mercy spoke highly of the scholars. Water Island proudly said: "it can be said that the LCD in principle it is very difficult to achieve as this such a high-contrast, therefore, this Panel is technically a far-reaching. "As in the Shui Yu said, the contrast of the LCD Panel and other basic performance is constantly improving, self-luminous display weakness also gradually to overcome from the contrast of the 1 million can be seen in the LCD.
Ma bin pointed out, the LCD Panel "in the basic performance numerical competition has ended, it is expected that the next step will be to show the true sense of the competition phase." "The depth of the black and the performance of value, the LCD is getting into the difficult emotional expressive aspects show competition stage. If you want to target the primary monitor, it must meet like CRT-like texture ".
