Microdisplay from Displaytech

Displaytech Inc. has developed the LightView VGA, WVGA and SVGA (LV-VGA, LV-WVGA, LV-SVGA) microdisplays that tout high image quality and power efficiency for next-generation CE devices including micro-projectors, head-mounted displays and mobile communications devices, while delivering lower manufacturing costs and faster time to market.

The compact, single-panel microdisplays leverage the company's ferroelectric liquid crystal on silicon (FLCOS) technology, which combines patented advances in the use of ferroelectric materials with a proprietary, VLSI semiconductor. The technology is said to deliver fast switching speeds and superior optical quality to achieve full-color video images that are free of motion smearing.

In addition, the microdisplays incorporate the display panel and control circuitry into the package for a fully integrated display controller that requires no additional circuitry to interface digital video. They also offer low-power consumption, which extends product battery life, and support industry standard digital interfaces.

The LV-VGA offers 640 x 480 full-color pixels with a 9.2mm active area diagonal; the LV-WVGA offers 852 x 480 resolution with an 11.25mm active area diagonal; and the LV-SVGA offers 800 x 600 with an 11.5mm active area diagonal. All three microdisplays support consumer product temperature ranges with integrated temperature compensation; operate at very low-power, typically at 100mW or better, with a 60Hz frame rate, and feature adjustable brightness and gamma settings.

The LightView microdisplays are said to offer superior image quality thanks to an all-digital pixel architecture. Each LightView offering also features a programmable color matrix processor and adjustable color field durations.
