GENEVA--STMicroelectronics today (March 27) said it has filled in the last gap of its cellular-phone chip offering with the introduction of two new liquid-crystal display (LCD) drivers. The new ICs integrate complete controller and driver functions for 65-by-128 column black-and-white graphic LCDs, said the European chip maker.
"Our goal is to become a one-stop shop for display driving solutions," said Pietro Menniti, general manager of ST's Industrial and Power Supply Division. The company is attempting to leverage its mixture of process technologies and production facilities to greatly expand its role in cell-phone displays.
ST said its STE2000 and STE2001 contain all of the circuits needed to control and drive displays, including graphics functions and a selectable interface for connection to I2C, serial or parallel ports. No external components are required, said the company. The two driver chips are similar except for their mechanical layout of bonding pads.
Additional display drivers are also being developed for gray scale and color twisted nematic (STN) LCDs. Thin-film transistor (TFT) and other new display technologies are also being pursued by ST's development labs.
STMicroelectronics did not release pricing information for the new LCD driver chips, but it said initial samples have been delivered to major display manufacturers, and the parts are now ready for volume production.
