Abstract: A highly flexible, frame rate controllable liquid crystal display (LCD) display driver circuit is designed. The driver circuit is powered by an external power supply and can operate in high performance or low power mode. On the basis of the universal LCD drivercircuit, a pre-frequency generator is added to achieve a frequency rate between 30-100 Hz highly flexible and programmable. On the basis of voltage regulation, the dead time duration regulation can be inserted to improve the contrast regulation and the low power performance of the circuit. The driver circuit provides a variety of driver options, driving up to 216(8×27) LCD pixels.
