The present disclosure discloses a source driving circuit, a driving method and a display device, so as to improve the large viewing angle deviation existing in the prior art, and increase the complexity of the pixel control circuit when improving the large viewing angle deviation, and reduce the pixel The question of opening rate. The source drive circuit includes: a gamma generation circuit, a gamma adjustment circuit, and a control circuit; the gamma adjustment circuit is configured to determine a value corresponding to each of the gamma reference voltage pairs according to multiple pairs of the gamma reference voltage pairs. The gamma reference voltage corresponds to the first output voltage, the second output voltage, the third output voltage and the fourth output voltage; the control circuit is configured in the first image frame to drive the display with the first output voltage , in the second image frame, the display is driven by the second output voltage, in the third image frame, the display is driven by the third output voltage, and in the fourth image frame, the display is driven by the fourth output voltage.
Description
technical field [0001] The present disclosure relates to the field of display technology, and in particular to a source driving circuit, a driving method and a display device. Background technique [0002] The mainstream display on the market today is still Liquid Crystal Display (LCD), but there is an inherent defect in LCD liquid crystal display, that is, when viewed at a large viewing angle (view angle), the optical brightness curve cannot meet Gamma 2.2, and LCD display The phenomenon of color shift occurs, and the larger the viewing angle is, the more serious the phenomenon of color shift is, such as figure 1 As shown, that is, when the viewing angles between the human eye and the liquid crystal display panel are 0 degrees, 30 degrees, and 45 degrees, the observed brightness is different, that is, the larger the viewing angle, the greater the brightness shift. [0003] At present, the main method to solve the large-view role deviation is: by adopting the pixel design o...
