Pixel driving method and pixel driving system

Abstract

A pixel driving method disclosed by the present invention comprises the steps of detecting the display mode of an LCD at a current frame; when the current frame is detected to be in a non-heavy load picture mode, using a processing unit to send a first frequency signal to a sequential control circuit; when the current frame is detected to be in a heavy load picture mode, using the processing unit to send a second frequency signal to the sequential control circuit; using the sequential control circuit to receive the first frequency signal and output a sequential control signal with a first working frequency at the next frame, or using the sequential control circuit to receive the second frequency signal and output the sequential control signal with a second working frequency at the next frame, wherein the first working frequency is higher than the second working frequency; using a data drive circuit and a scanning drive circuit to receive the sequential control signal and then drive the pixel electrodes to work. According to the present invention, the heating problem of the data drive circuit and the problem that the temperatures of the equipment rise are relieved, the working stability of the LCD is kept, and the LCD is prevented from being damaged.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel driving method and a pixel driving system. Background technique [0002] Thin Film Transistor-LCD (Thin Film Transistor-LCD, TFT-LCD) has been developed rapidly and widely used in recent years. It is widely used in display devices of portable mobile electronic products, such as mobile phones, digital cameras, handheld computers, GPRS, etc. mobile products. A liquid crystal display panel is generally formed by pairing a color filter substrate and an array substrate, and a liquid crystal layer is encapsulated in the space between the two substrates. The array substrate mainly includes scanning lines, data lines and pixel electrodes. The scanning lines and the data lines are arranged perpendicular to the direction. The pixel electrodes are formed in the pixel area where the scanning lines and data lines are interlaced. The sent signal is sent to the corresponding ...
