Abstract: The present invention provides an array substrate and a liquid crystal display. The liquid crystal display panel provided by the embodiment of the present application comprises an array substrate. The array substrate reduces the pretilt angle conflict between two adjacent areas by canceling the main electrode of the buffer area, or setting projection part on the array substrate after canceling the main electrode of the buffer area, adding DBS electrodes, etc. This prevents the problem of mutual obstruction of liquid crystal molecules when deflecting, thereby improving dark mass and solving the problem of uneven display.

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.

Abstract: The present application provides a display panel, a splicing screen, a display device, and a method for manufacturing the display panel, and relates to a display technology field. In the display panel provided by the present application, a plurality of light-emitting units are mainly arranged in an array on a surface of the display panel corresponding to a frame area so as to visually weaken or eliminate an influence of the frame area on a display effect of the display panel. At a same time, the present application also utilizes a driving circuit layer in an array substrate in the display panel to directly drive the light-emitting units, which simplifies a structure and a driving method of the display panel and is especially suitable for a splicing screen using the display panel as a unit screen.

Abstract: The present application discloses a liquid crystal display panel, a method for manufacturing the liquid crystal display panel, and a curved display. The liquid crystal display panel is configured with an alignment layer only on an array substrate, but not on an opposing substrate opposite to the array substrate. After photo-alignment, a pretilt angle of liquid crystal molecules near the array substrate is greater than a pretilt angle of liquid crystal molecules near the opposing substrate to effectively mitigate a problem of “black clusters.”

Abstract: A bend limiting device includes a flexible support film and limiting chains. The limiting chains are disposed on the flexible support film. Each of the limiting chains includes limiting blocks. Each of the limiting blocks includes limiting structures. One of the limiting structures of one of the limiting blocks is connected to one of the limiting structures of another one of the limiting blocks. When the bend limiting device is bent, two connected limiting structures of two adjacent limiting blocks limit a minimum value of an included angle formed between the two adjacent limiting blocks, so a radius of curvature of each of the limiting chains is limited to be greater than a preset value without being excessively bent. The bent limiting device protects a flexible display panel of a flexible display device from being improperly bent, so as to extend a lifespan of the flexible display device.
