Description

The NT7702 is a 240-bit output segment/common driver LSI suitable for driving large scale dot matrix LCD panels using as PDA/personal computers/work stations. Through the use of SST (Super Slim TCP) technology, it is ideal for substantially decreasing the size of the frame section of the LCD module. It is good as both a segment driver and as a common driver, and a low power consuming, highprecision The NT7702 is a 240-bit output segment/common driver LSI suitable for driving large scale dot matrix LCD panels using as PDA/personal computers/work stations.
