Widescreen LCD is easy to design-in

A 7in widescreen TFT-LCD module complete with interface, power sequencing and OSD control already integrated eases design challenges and reduces time to market for new products.

Anders Electronics has introduced a 7in widescreen TFT-LCD module complete with interface, power sequencing and OSD control already integrated, to ease design challenges and reduce time to market for new products.

The complete module is based on a TPO (formerly Toppoly) TFT panel and is RoHS compliant.

The module comprises a 7in, active matrix digital-input TFT-LCD panel with 256K colour depth, featuring low temperature polysilicon (LTPS) technology that ensures high reliability, low power consumption and thin construction.

The display has a wide viewing angle - up to 140 degrees left to right, contrast ratio of 600:1 and a resolution of 800 x 480 pixel (W-VGA).

The CCFL backlight built in gives a screen brightness of 500cd/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 onboard 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 onboard DC/DC convertor 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 +12V DC 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 touchscreen 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.
