Himax Introduces New Generation TFT-LCD Single Chip Driver

Taiwanese company Himax Technologies has introduced its new generation single chip display driver for TFT-LCD handsets, the HX8352.

The new chip is among the world's first that integrates features including Content Adaptive Brightness Control, MDDI and MIPI interface, RGB separated gamma correction, and supports up to Ultra Wide QVGA (240X480) resolution, suitable for multimedia-rich portable devices, such as 3G/3.5G and smart phones. The HX8352 has passed customer qualifications and is ready for mass production.

There is an increasing demand for handsets that transmit multimedia data, and as a result, there is a greater adoption of larger, higher resolution, and higher power consuming panels by handsets. In order to provide high quality pictures on handsets while controlling cost and power consumption at a relatively low level, Himax has successfully integrated several unique features to produce a low-cost single chip that emphasizes on high speed data transmission and low power consumption.

Himax says it has already seen strong interest in the HX8352 from several of the company's Taiwanese, Mainland Chinese, Japanese, Korean handset panel module customers, and also Tier-1 handset makers. Several of the company's customers have already adopted the new chip for design-in activities. With its advanced features and early time to market, the company believes that this latest display driver can provide great value to customers in their next generation of multimedia-rich and power conscious portable devices.

The HX8352 supports 262K colors primarily for wide QVGA (240×400 or 240×432), and ultra wide QVGA (240×480). WQVGA and UWQVGA panels provide handset makers with more flexibility in industrial design, user interface, and feature applications.

In addition to regular functions, the HX8352 integrates unique features enabling better TFT-LCD panel performance for multimedia-rich portable devices, such as 3G/3.5G and smart phones. Content Adaptive Backlight Control (CABC) fine-tunes backlight brightness by analyzing and processing the display content, which would result in an up to 50% power saving in backlight power while maintaining a vivid display quality.
