Abstract

The present application relates to an array substrate and a display motherboard. The array substrate is provided with a storage capacitor circuit. The array substrate has a first area and a second area, and the second area is located at the edge of the array substrate and surrounds the first area. The storage capacitor circuit includes a first capacitor circuit and a second capacitor circuit. The first capacitor circuit includes a plurality of first storage capacitors and is located in the first area. The second capacitor circuit includes a plurality of second storage capacitors and is located in the second area. The first capacitor circuit includes a plurality of second storage capacitors and is located in the second area. The capacitance of the storage capacitor is greater than that of the second storage capacitor. The present application can compensate the sub-pixels located in the second area with low display brightness, so that the brightness thereof is consistent with the brightness of the sub-pixels located in the first area, thereby improving the display quality.

Description

technical field

[0001] The present application relates to the field of display technology, in particular to an array substrate and a display motherboard. Background technique

[0002] With the development of display technology, various display panels, such as organic light emitting display panels, appear. During the production process of the display panel, it is usually formed after cutting on a large display motherboard (a motherboard that can be cut into multiple display panels). However, the display motherboard is usually formed on a large array substrate (that is, a substrate on which a driving circuit is formed on a large base substrate).

[0003] Due to the influence of the production process (such as the uneven film quality of the plasma-enhanced chemical vapor deposition (PECVD) film), the display panel formed in the edge region of the display motherboard (the part near the side of the display motherboard) is easy to When the grayscale is low, the brightness is dim...
