Display panel display control method, device and circuit

Abstract

The invention provides a display panel display control method, device and circuit, which are used for reducing display power consumption of a display panel under the precondition of guaranteeing the quality of image information. The display panel display control method comprises the following steps: when the display panel is in a play mode, storing image information received from a signal source into a first storage space, reading the image information in the first storage space and sending the image information to the display panel for carrying out image display; when the display panel is in a pause mode, storing the image information received from the signal source into a second storage space; and when the display panel is switched from the pause mode to the continuous play mode, reading the image information in the second storage space and sending the image information to the display panel for carrying out image display.

Description

technical field [0001] The invention relates to the field of liquid crystal display panel systems, in particular to a display control method, device and circuit of a display panel. Background technique [0002] At present, the way to reduce power consumption of smart mobile terminals is mainly from the perspective of driving hardware circuits, choosing low-power integrated chips, low-power peripheral circuit structures, and so on. For example, in the patent "A Handheld Mobile Media Digital Flat Panel Display Control System", the author uses a low-power FPGA device, which includes three parts: a programmable logic module, an output and input module, and internal wiring. The logic module includes a YUV-RGB signal conversion circuit and a flat panel display timing control circuit, and their output signals directly drive an external display panel through the input and output modules through the internal wiring. The benefits of low-power field programmable gate array (FPGA), ARM...

Problems solved by technology

However, there are two disadvantages as follows: one is that the display color depth of the displayed image is reduced, thereby reducing the clarity of the displayed image; the other is that although the image information cached in the SDARM is reduced, the SDRAM still needs to be refreshed continuously. Increase the display power consumption of the display panel

However, this technology will reduce the display quality of the display screen and increase the complexity of the software code

[0007] To sum up, the methods for reducing the display power consumption of the display panel in the prior art cannot reduce the display power consumption of the display panel on the premise of ensuring the quality of the displayed image.
