Leadis Technology Inc. has announced sample availability of two color STN driver ICs aimed at mobile handset displays. The LDS195, a 262K color driver with integrated controller, supports 128 (RGB) x 160 resolution displays, and the LDS194, a 65K color driver with integrated controller, supports 98 (RGB) x 70 and 98 (RGB) x 64 resolution displays.

The LDS194 65K color and LDS195 262K color STN LCD driver ICs are highly integrated high-performance devices that incorporate display RAM, an on-chip oscillator and temperature compensation for adjustment of VLCD and frame frequency to provide fine tuning of the screen for optical visual performance, said Leadis.

The display drivers also include advanced programmable display features such as partial display mode for power-reducing screen saver controls, block inversion for low crosstalk and color depth selection for enhanced screen performance.

Built on advanced CSTN process technology, both devices implement a mixed PWM /FRC architecture to provide high-quality video rendering and multiple line addressing, which enables fast screen response times for additional visual performance while reducing power consumption, said the company.

Samples available today.
