SEOUL -- Samsung Electronics Co. Ltd. today announced development of a new LCD driver ICs for mobile phones supporting the reproduction of up to 65,000 colors on liquid crystal displays vs. 256 colors in today's phones.
Samsung said its new driver is unlike other devices currently on the market in that it has both a common driver and segment driver integrated into the same chip. This combination makes it less costly to produce LCD modules and phones, according to the Korean chip maker.
Samsung said its new driver chip is designed for super-twisted nematic STN-LCDs. The device can be used for 256 or 4,096 colors in addition to the full 65,000-color capability, according to the company.
The driver IC can improve the performance of mobile-phone central processing units (CPUs) by using multiple-line selection (MLS) to transmit data from more than one data line at a time, said Samsung. The MLS feature quadruples processing speeds while reducing power consumption by about 60%, said the company.
About 37% of the mobile phones sold in 2003 are expected to be equipped with color displays, according to Samsung. The company estimated that the total number of color phones could be 180 million next year.
Samsung plans to start volume production of the color LCD driver in July. The company said it is aiming to capture about 15% of the overall market for LCD drivers by 2003.
