Techwell Inc. expands its range of in-car LCD display processors with the release of the TW8823 LCD controller for automobile centre console and rear seat entertainment applications. The device surpasses prior models in both video performance and flexibility for automotive infotainment applications.

Techwell's TW8823 features an embedded microcontroller, LED/CCFL backlight controllers, a four-wire resistive touch screen controller, analogue and digital TCON, and a multi-window 16-bit (65K colour) bit-map on-screen display. Embedding these features in the controller reduces the system's overall BOM cost and provides system designers with an extremely flexible design platform.

"Each key feature of the TW8823 has been requested by our automotive customers to meet applications in the booming automotive infotainment industry," said David Nam, VP of sales and marketing, Techwell. "Better OSD to improve the GUI, and an improved MCU to support LIN bus and CAN, is of particular importance. Our new TW8823 LCD controller has all that, and more. It's the highest spec display controller chip we've made to date."

Customers can leverage the TW8823 across multiple platforms to directly display video and graphic content from multiple sources, including TV tuners, DVD players, navigation/GPS receivers, PCs, etc. The TW8823 can support a wide variety of both digital and analogue LCD panels with resolutions up to WXGA, and also has an integrated single channel LVDS interface to directly drive LVDS-based LCD panels. Embedded image enhancements include: programmable CTI, hue, brightness, saturation, contrast and sharpness; black/white stretch; programmable favourite colour enhancement (up to three colours); and programmable gamma correction tables.
