Techwell Inc., a designer of mixed-signal ICs for multiple video applications in the consumer, security surveillance and automotive markets, announced the expansion of its line of LCD display processors with the introduction of the TW8804, TW8806 and TW8807.

The new processors target in-car LCD displays, including front console, rear seat and flip down displays. The TW8800 family offers image processing capabilities, including edge enhancement and black/white stretch functionality in addition to an integrated programmable timing controller and multiple analog and digital video inputs.

According to Tom Krause, director of business development at Techwell, the TW8804, TW8806 and TW8807 processors are designed to "provide a high video quality, small form factor, low power and cost effective solution to customers developing in-car displays to support entertainment, navigation and driver information applications."

The TW8804 contains the logic required to convert standard video signals into the digital control and data signals required to drive various TFT panel types. An integrated YPbPr/RGB component input allows direct connection to DVD, PIP and TTX sources. It supports TFT panel resolutions up to 1,280 x 1,024 (SXGA/WXGA) with either 1- or 2-pixel/clock formats. For more natural scaling, the TW8804 includes a Panorama/water glass feature with scaling from 4:3 to 16:9. This product also includes multiple video enhancement functions, including low angle improvement/edge enhancement, black and white stretch and sharpness control. In addition, the TW8804 integrates a programmable timing controller that is said to reduce system costs for in-car LCD display customers.

The TW8806 and TW8807 are pin-to-pin compatible LCD display processors with an embedded NTSC/PAL/SECAM TV decoder and on-chip programmable timing controller. According to Techwell, this level of integration enables the panel to be used as a stand-alone LCD display for in-car display applications, including rear seat and flip down entertainment systems. Both the TW8806 and TW8807 cores operate at 1.8V, and are packaged in a small 128-pin PQFP package. The TW8806 supports digital LCD panels, while the TW8807 supports analog LCD panels.

Manufactured by Taiwan Semiconductor Mfg Co. Ltd, the TW8804 utilizes a 160-pin LQFP package. The TW8804 began mass production in October 2005, while the TW8806 and TW8807 will begin sampling in Q1 2006 and will commence mass production in Q3 2006.
