Sharp shows 7 “-tabletscherm with backlight in three colors




Screen Manufacturer Sharp at CES a prototype of a 7 “-beeldpaneel shown based on MEMS-IGZO technology. This technique needs compared to a larger color gamut LCD allow while reducing power consumption.

The screen that Sharp has developed along with the Pixtronics company, is a triple backlight which red, green and blue light can radiate. For each sub-pixel is a tiny MEMS shutter. That is a tiny plate with narrow slots, which can quickly be pushed back and forth. By controlling synchronize the different backlight colors thereby, the screen can mix colors and thereby show color tones.

Because the light from the backlight does not have to be through a color filter, it is according to Sharp possible to give a wider color gamut than in normal weather LCDs. That is up to 120 percent of the NTSC color space, claims the manufacturer. In addition, the brightness should be higher than for TFT-LCDs and screens were less relfecteren.

Another advantage over LCDs is the versatility of the control, says Sharp. By slowing down the speed of the MEMS shutter should be possible to drastically reduce the power consumption. This would be accompanied by a reduction of the color palette. It is also possible to generate a monochrome image, which according to Sharp ensures a further reduction of the power consumption.

The screen shown at CES is a prototype and Sharp himself has no plans to integrate it into a real product. The manufacturer hopes to conclude contracts for screen supplies to other manufacturers, but would not say whether companies have already shown interest.
