The invention relates to the technical field of image processing, and discloses a liquid crystal display control method, a liquid crystal display control system and an intelligent synchronization module. The liquid crystal display control method provided by the invention comprises steps: the current frame synchronization frequency and the refresh frequency in a frame cache area are acquired; according to the current frame synchronization frequency and the refresh frequency in the frame cache area, whether the frame synchronization frequency of the liquid crystal display needs to be updated is judged; if yes, the frame synchronization frequency is updated; and if not, the current frame synchronization frequency is kept unchanged. By adopting the technical scheme of the invention, the liquid crystal display controller can dynamically adjust the frame synchronization frequency according to the refresh frequency of the liquid crystal display, the memory bandwidth of a frame memory can be used effectively, and the power consumption of the overall liquid crystal display system is reduced.
Description
technical field [0001] The invention relates to the technical field of image processing, in particular to a control method and system of a liquid crystal display and an intelligent synchronization module. Background technique [0002] In the prior art, the control system of liquid crystal display such as figure 1 As shown, the system generally includes: a liquid crystal display (Liquid Crystal Display, LCD for short), a controller of the liquid crystal display, a central processing unit (Central Processing Unit, CPU for short) and a memory; The frame synchronization (vertical synchronization signal, referred to as VSYNC) frequency to send image data to the LCD. In the prior art solution, LCD generally needs three timing signals: a frame synchronization signal VSYNC, a horizontal synchronization signal (Chorizontal synchronization signal, HSYNC for short) and a pixel clock signal VCLK. [0003] Among them, VSYNC is a frame synchronization signal, and every time VSYNC sends ...
