Abstract: The present invention provides a full grayscale subjective consistency optical data obtaining method and a splicing display panel, an initial splicing display panel includes splicing and disposing first display panel (liquid crystal display panel) and second display panel in different types. The method includes: obtaining a plurality of bonding point colors, sets of reference bonding point optical parameters and sets of bonding point optical parameters of the first display panel and the second display panel corresponding to the bonding point colors respectively, and determining non-bonding point optical parameters in the second display panel corresponding to non-bonding point colors between adjacent two of the bonding point colors. A display image of the second display panel under effect of each set of the bonding point optical parameters is subjectively consistent with a display image of the first display panel under effect of a set of the reference bonding point optical parameters.

Abstract: Embodiments of the present disclosure are directed to a driving circuit, a driving method, and a display panel. The driving circuit includes a driving transistor, a writing module, a compensation module, a light-emitting control module and a light-emitting device. The driving transistor has a first gate connected to a first node, a second gate connected to a second node, a source connected to a first power supply terminal, and a drain connected to the third node. The writing module is connected to the first node and the third node. The compensation module is connected to the first node, the second node and the third node. The light-emitting control module is connected to the third node and the fourth node. An anode of the light-emitting device is connected to the fourth node, and a cathode of the light-emitting device is connected to the second power supply terminal.

Abstract: According to an embodiment of the present disclosure, a display screen, a display device, and a method for manufacturing the display screen are disclosed. The display screen includes a display panel and a light bar. The light bar includes an array substrate and a plurality of light emitting elements, and a first gap is provided between two adjacent light emitting elements. A reflecting wall is arranged in the first gap between at least two adjacent light emitting elements. By arranging the reflecting wall, the side light of the light emitting elements can be reflected upwards, thereby reducing an emission angle of the light bar.
