7-inch TFT-LCD module features PC / video input and single supply voltage

The module comprises a 7-inch, active matrix digital-input TFT-LCD panel with 262k colour depth, featuring low temperature poly silicon (LTPS) technology that ensures high reliability, low power consumption and thin construction. The display has a wide viewing angle - up to 140° left to right, contrast ratio of 600:1 and a resolution of 800 x 480 pixels (W-VGA). The CCFL backlight built in gives a screen brightness of 500 cd/m2 screen brightness, making the display suitable for use in a wide range of domestic, retail and industrial ambient environments. The use of LTPS architecture and low power design techniques reduces total power consumption for the combined panel and backlight to less than 6W.

The interface board occupies the same footprint as the TFT-LCD panel and attaches to the rear of the display, creating a slim assembly only 24mm deep. The on-board video decoder accepts PC-VGA input as well as S-Video, composite video and YpPbBr component video, with connectors for CVBS, S-Video and YPbPR as well as a standard D-sub 15 connector for analogue VGA input. The package includes an on-board DC-DC converter generating all the supply voltages for the TFT-LCD, as well as the inverter needed for the CCFL backlight. The designer needs only to provide a +12VDC supply, and video in the chosen format, enabling rapid evaluation and design of solutions to modern display challenges.

Applications for the new display module include security systems, video games, door entry systems, video phones and portable television, as well as a wide range of portable and panel mounted instruments. A touch-screen is currently being developed for the module.

In addition to the turnkey module, Anders Electronics also supplies the TFT-LCD panel and interface board as individual components, giving designers extra flexibility, faster demonstrations and proof-of-concept, with quicker design and integration.
