On January 9th, US local time, Sony presented the next generation of self-luminous display technology "Crystal LED Display" at the 2012 Consumer Electronics Show (CES) press conference. Several 55-inch full HD prototypes appeared. On the booth.
Since the announcement of the withdrawal of SLCD joint venture shares at the end of last year, and the OLED development turned to commercial rather than consumer, Sony's layout on the next generation of display technology has been a mystery, this time the Crystal LED Display shows Sony in a certain degree A reserve of core technology in the field of flat panel display. At the same time, Sir Howard Stringer, president of Sony Group, also said that it will continue to promote the development and commercialization of OLED.
According to the technical specifications provided by Sony, Crystal LED Display is a Sony's unique way of self-illuminating display technology, through the color of each pixel on the RGB three-color ultra-fine LED light-emitting diodes. Therefore, a full HD screen with a total pixel size of about 2 million pixels will use about 6 million LEDs.
Sony said that the display in this way can display higher contrast in various brightness environments, have a wider color gamut and faster video response speed, compared with existing LCD liquid crystal and plasma display methods. A wider viewing angle and lower energy consumption can be achieved. At the same time, due to its structure, the "Crystal LED Display" display technology is also very suitable for large-size TV screens.
Taking the prototype exhibited in this example as an example, it can achieve a contrast ratio of about 3.5 times in a bright environment, a color gamut range of about 1.4 times, and a corresponding video speed of about 10 times (the above values ​​are based on Sony's existing model TV products. inferred). Its brightness is about 400 cd/m2, the viewing angle is about 180 degrees (that is, equivalent to no viewing angle problem), and the contrast (under dark light) exceeds the measurable upper limit (because the LED lighting unit can be completely turned off, so black is pure Black), NTSC (xy) color gamut ratio is higher than 100%, panel average energy consumption is less than 70W - this is an almost perfect parameter for a flat panel display product.
From the naming method, Crystal LED Display is different from OLED in that it uses inorganic light-emitting diodes. This illuminating technology has a longer history than OLEDs and is widely used. However, due to the technical bottleneck of small-sized LEDs, LEDs are often used for line source, area array light source and large screen dot matrix image display. In principle, self-illumination brings advantages in contrast, light efficiency, and color saturation.
The reporter watched the contrast demonstration of Crystal LED Display and ordinary LCD TV. The contrast, color saturation, viewing angle and dynamic picture clarity left a deep impression on the reporter. Especially in the dark scene of the dark environment (small black house), the Crystal LED Display can image the black of "reaching the fingers". When comparing motion pictures, the Crystal LED Display also maintains a sharpness close to the static picture, and does not see the blur caused by the trailing tail. At the same time, the uniformity of the picture does not see obvious deficiency, which used to be a problem that plagued the display of large-screen LEDs.
Through careful analysis of the screen shots taken by the reporter, the reporter found that each pixel area of ​​the Crystal LED Display is small, and it is difficult to distinguish the arrangement pattern of RGB pixels. Only one color point can be seen. It can be seen that Sony is on the LED miniaturization. The skill. Interestingly, under the high-speed shutter, the reporter found that the Crystal LED Display is displayed in a similar scanning manner, which means that the entire screen does not appear on the screen, which is significantly different from the LCD TV next to it. Looking closely at the photo, you can see the edges of the image that are slightly tilted horizontally, and the edges of the pixels are gradually darker and have no sharp boundaries. The reason for this design may be based on energy savings, heat dissipation or increased dynamic resolution.
