Sharp announces four-color 3D LCD displays

Sharp has announced the first four-primary-color 3D LCD, claiming it will give a brighter image than current models with very little ghosting.

It’s claimed to be a big improvement on the usual shutter-based 3D technology, which Sharp says suffers from low brightness and crosstalk. It still needs special glasses, though.

It uses four base colors, adding yellow to the usual trio of red, green and blue. This means that light transmission through the panel is more efficient, and provides a wider range of colors.

The system is also claimed to reduce flickering by refreshing images much more quickly, and to be 80 percent brighter than existing models. Cross-talk, or ghosting, is reduced through the use of side-mount scanning LED backlight technology.

TVs based on the display will go on sale in Japan by the middle of the year under the company’s Aquos brand, with global sales set to start by year-end. Sharp says it hasn’t decided whether or not to supply the displays to other manufacturers.

The company says it expects 3D displays to account for up to 10 percent of TV sales this year, rising to as much as 30 percent in the next few years.
