V5240K

V5240K is used to 81X120 STN LCD single driving controller. The LCD chip integrates special DCC (Direct Capacitor Coupling) driving architecture to achieve near crosstalk free images. Except the low power COM and SEG drivers, it contains high-power LCD power supply, bias voltage generation, temperature compensation, timing generation and graphic data memory. Meanwhile, it is used to advanced circuit design techniques to reduce external components and minimize connector size to achieve extremely low-power consumption.
