Description
The HD66523 is a common driver for liquid crystal dot-matrix graphic display system. This device incorporates a 240 liquid crystal driver and an oscillator, and generates timing signals (line scanning signals and frame synchronizing signals) required for the liquid crystal display. It features a new LCD driving technique for better quality of display and low power dissipation. Combined with the HD66522, a 160-channel column driver with an internal RAM, the HD66523 is optimal for use in displays for portable information tools.
