From PC World: Sharp is close to commercializing its first product that uses a MEMS display—a new type of flat-panel display that boasts deeper and richer colors than traditional LCD screens and lower power consumption.
The screen was developed over the last three years with Qualcomm subsidiary Pixtronix and Sharp hopes it will one day replace LCD screens in portable devices.
That’s a big deal for both Sharp and Qualcomm. Sharp is a market leader in LCD and has pioneered numerous innovations in the technology while Qualcomm has been trying to popularize MEMS for several years. Qualcomm has fitted a MEMS display in its prototype Toq smartwatch.
The way MEMS displays control the light from each pixel is fundamentally different than the way LCD displays work.
LCD screens are built on a bright, white backlight that sits at the rear of the screen. Each pixel is divided into red, green and blue subpixels with color filters. Current applied to the liquid crystal in front of each of those filters allows or blocks transmission of light of that color.
