摘要： An array substrate, a display panel and a display device are provided. The array substrate comprises pixel units. The pixel unit comprises four sub-pixel electrodes and at least one thin film transistor for controlling the four sub-pixel electrodes. Domain alignments of the four sub-pixel electrodes within the pixel unit differ from each other, and domain alignments of the four sub-pixel electrodes within the pixel unit have a mirror-symmetrical distribution in up and down directions and in left and right directions.

摘要： A data compensation method and apparatus for a liquid crystal display screen are described herein. Said method comprises determining a timing length ΔT′ from the last turn-off of the liquid crystal display screen upon turn-on of the liquid crystal display screen, and determining a mura data compensation table am called at the time of the last turn-off; determining a mura data compensation table to be called at the time of the present turn-on according to a pre-set time length T needed for stabilization of mura, mura data compensation tables corresponding to pre-set different time periods, said timing length ΔT′, and said mura data compensation table am; performing data compensation starting from the determined mura data compensation table to be called at the time of the present turn-on. By using said method for data compensation, an appropriate initial data compensation table can be determined to obtain a better compensation effect.

摘要： A data input unit, a data input method, a source drive circuit and a display device. The data input unit includes: an input module, configured to provide a normal display data; a setting module, configured to preset one or more predetermined display data; and a selection module, configured to select the input module to provide the normal display data to a data input end or select the setting module to provide a special predetermined display data to the data input end, according to the one or more external control signals. Thus, besides a normal driving function, other special driving functions also may be provided for special display demands so as to improve the performance and display quality of a display device.
