Samsung Electronics Co., Ltd., the world's largest provider of thin-film transistor, liquid crystal display (TFT LCD) panels, begins producing seven-inch LCDs in September to take the lead in the WVGA display market for mobile devices. The seven-inch LCD is well suited for high-end multimedia products such as handsets for digital multimedia broadcasting (DMB), portable multimedia players (PMPs), portable DVD players, and portable navigation systems. Samsung plans to expand the seven-inch LCD production capacity to 10 million units by 2007. The company unveiled its seven-inch display at the International Meeting on Information Displays, held in Daegu, Korea last month.

Samsung Electronics - Silicon LCD
Samsung Electronics Executive Vice President Yun Jin-hyuk, chief of the Mobile Display Business Team, said, "This technology breakthrough enables our customers to develop truly differentiated portable electronic devices with higher resolution, wide aspect ratio mobile displays. Using a single-chip packaging solution, we have integrated most of the display electronics on an amorphous silicon LCD."

Mobile LCD with WVGA resolution
Until now, the market for mobile LCDs with WVGA resolution has been centered around eight- and nine-inch models. Samsung's single-chip solution replaces the four-to-seven driver ICs common for a seven-inch platform. By utilizing advanced integration techniques, Samsung's new mobile display eliminates the need to have a separate printed circuit board that contains timing control and power components to drive the display. Previously, multi-chip approaches have limited the design of very slim portable electronics.

Samsung 7-inch LCD display - For slim & efficient designs
Samsung has applied its proprietary amorphous silicon gate technology to the development of the new seven-inch LCD, enabling the gate driver IC to be fabricated directly on the glass substrate, with the timing controller integrated within the driver IC. An onboard digital chip eliminates the need for mobile developers to design their own circuits. The overall circuit footprint and component count have been reduced to about 1/3 of a conventional seven-inch LCD, inviting widespread adoption of the new seven-inch LCD in slimmer, more efficient system designs.
