Sequence control circuit with electricity-saving function and control method

Abstract

Disclosed is a time sequence control circuit with the power-saving function, which comprises a receiver circuit, a processor and a first switch; the receiver circuit is used for receiving the first group of differential signals to generate a group of instruction signals. The processor is coupled with the receiver circuit and generates a first control signal according to the group of instruction signals. The first switch is coupled with the receiver circuit and the processor, and selectively cuts off the connection of the receiver circuit and a first power supply according to the first controlsignal. The power consumption for maintaining the starting of the drive circuit during the outer edge pixel transmission is reduced; thereby, the power consumption of the LCD is reduced and the heat output of the LCD is lowered.

Description

A sequential control circuit and control method with power saving function technical field The present invention relates to a timing control circuit and a related control method of a liquid crystal display, more specifically, the present invention relates to a timing control circuit and a related control method of a liquid crystal display with power saving function.

Problems solved by technology

Therefore, even if the user cannot see the black screen generated by the peripheral pixels, the reduced-swing differential signal interface between the timing control circuit 110, the data driving circuit 120, and the gate driving circuit 130 still needs to be in the activated state, resulting in unnecessary waste of electric energy.
