Display control circuit, display control method and display device

Abstract

The present invention relates to the field of display technologies. Disclosed are a display control circuit, a display control method, and a display apparatus. The circuit comprises a signal supply unit, for outputting an image data signal; a timing control unit, for processing the image data signal into a signal recognizable by a drive circuit unit; a storage unit, for storing the foregoing recognizable signal and transferring the signal to the drive circuit unit; a sample storage unit, connected to the signal supply unit, and for collecting and storing the image data signal; and a sample comparison unit, for comparing a current frame signal output by the signal supply unit and a previous frame signal stored in the sample storage unit, and controlling on or off of the timing control unit according to a comparison result to control whether a signal stored in the storage unit needs to be updated. In the embodiments of the present invention, when a signal output by the signal supply unit is unchanged, a part of modules in the timing control unit are turned off, and the storage unit provides the drive circuit unit with an image signal to display, thereby implementing intermittent working of a part of modules, and lowering power consumption of the circuit.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display control circuit, a display control method and a display device. Background technique [0002] Traditional display control circuit, its structural schematic diagram is as follows: figure 1 Said, including: a signal supply unit, which outputs the image data signal that needs to be displayed on the display screen; a timing control unit, connected with the signal supply unit, receiving the image data signal output by the signal supply unit, and processing the signal, converting it It is a signal that the driving circuit unit can recognize, so that the driving circuit unit can further output the signal to the display screen for image display. Regardless of whether the final image displayed on the display screen changes or not, the display control circuit refreshes from time to time to reflect the image data signal output by the signal supply unit on the display screen. ...

AI Technical Summary

Problems solved by technology

[0003] In some applications, such as billboards, etc., the screen does not need to be refreshed constantly, and more is a static screen, but the display control circuit still refreshes the screen according to the circuit frequency from time to time, which increases the power consumption of the entire display device.
