Driving mode switching method and module and display device

Abstract

The embodiment of the invention provides a driving mode switching method and module and a display device, and relates to the field of display technologies. It can be avoided that because a displayer is fixed into a row turning mode or a line turning mode or a frame turning mode, crosstalk is prone to occurring or because the display is fixed into a point turning driving mode, display abnormal conditions may occur. The method includes the steps that a preprocessed reference image is obtained; image feature recognition is performed on the reference image, wherein an image feature includes an image edge and an image color region; according to the result of performing image feature recognition on the reference image, division is performed on the reference image to generate a color block set contained by the reference image; according to the sequence of color blocks contained in the color block set, coupling voltage of all the color blocks and brightness difference values corresponding to the coupling voltages are calculated; according to the brightness difference values corresponding to the coupling voltages, a crosstalk result is judged; according to the crosstalk result, driving mode switching is performed. The driving mode switching method and module are used for driving mode switching of the display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a driving mode switching method, a module and a display device. Background technique [0002] At present, in the field of display, especially in the field of small and medium-sized mobile display products, consumers' demand for display quality is getting higher and higher, which also promotes the use of thin film transistor liquid crystal display (English abbreviation: TFT-LCD, English full name: ThinFilmTransistor-LiquidCrystalDisplay) ) The flat panel display represented by ) constantly pursues higher display effects, so improving the PPI of the display has become a development trend. With the improvement of PPI, the size of the TFT drive unit is getting smaller and smaller, which results in higher precision requirements and smaller error requirements for the TFT manufacturing process. Therefore, it is more difficult to control the TFT characteristics and parasitic capacitance...

Problems solved by technology

However, one weakness of dot inversion driving is that the driving ability of the signal is relatively weak, so when the display adopts dot inversion, it is easy to display abnormally under certain conditions due to insufficient driving ability.

[0004] The driving method of traditional TFT-LCD adopts a fixed mode (such as fixed use of column inversion or dot inversion), but different driving methods have their own shortcomings, so the display is easy to show corresponding defects under certain circumstances.

For example, many TFT-LCDs are prone to vertical crosstalk under column inversion, and horizontal crosstalk is also prone to occur under row inversion. However, if the display is fixed with dot inversion, it may cause some abnormal display problems on the screen under certain conditions due to the driving ability.
