Abstract: The application discloses a liquid crystal display panel and a display device. In the liquid crystal display panel, each pixel unit includes a first sub-pixel and a second sub-pixel. The polarities of the data voltages received by two adjacent pixel units sharing the same data line are opposite. In each pixel unit, the driving timing of the first sub-pixel is earlier than the driving timing of the second sub-pixel, and the duty cycle of the scan signal received by the first sub-pixel is greater than the duty cycle of the scan signal received by the second sub-pixel.

Abstract: A display panel, a driving method, and a display device are disclosed. The display panel includes a plurality of pixel units, a gate driver, a source driver, a plurality of feedback lines, and a control module. The display panel is provided with the plurality of feedback lines electrically connected to the gate driver and the control module, such that the control module can detect turn-on time of the pixel units respectively located in at least two pixel areas through the plurality of feedback lines and adjust time when the source driver outputs data signals according to the turn-on time. This solves an issue of uneven display brightness due to inconsistent pixel charging time in the prior art.

Abstract: The present application provides a splicing display, a driving method, and a splicing display device. The splicing display includes first sub-display panels and second sub-display panels. A size and a number of the first sub-display panels are respectively same as a size and a number of the second sub-display panels in horizontal or vertical directions. The first sub-display panel and the second sub-display panel are misaligned by N rows/columns of sub-pixels in the horizontal or vertical directions. Misaligning N rows/columns of the sub-pixels can increase an accuracy of the splicing display, and splicing positions can be prevented from problems of misalignment and blurring.

Abstract: A data driving chip and a display device are disclosed. The data driving chip and the display device includes a signal identifying circuit between the digital signal processing circuit and the analog signal processing circuit. In this way, the signal identifying circuit could identify the signal in the display data signal. When the signal identifying circuit identifies the invalid display command signal, the signal identifying circuit controls the invalid display signal not to be outputted to the analog signal processing circuit such that the power consumption could be reduced.

Abstract: An array substrate and a display panel are disclosed. In the array substrate, array electrodes of at least a portion of pixel units that are adjacent to a base plate edge have areas that are gradually decreased from a base plate center toward the base plate edge. The portion of the array electrodes gradually decreased are arranged in a region of a display panel in which the brightness is relatively bright. If the areas of the array electrodes are decreased, the aperture ratios of the pixel units are reduced. After the aperture ratios of the pixel units are reduced, light transmission rate in an edge zone of the array substrate can be lowered. As such, the portion of the base plate edge of which light is relatively bright is made corresponding to the brightness of the base plate center, thereby realizing the improvement on the nonuniformity of periphery displaying.
