Problems solved by technology
[0003] In the prior art, in order to improve the transparency, a top emission structure is usually used to make a transparent display panel. Since the upper cover of the top emission is provided with structures such as a color filter and a black matrix corresponding to the pixel area of the lower cover, the alignment deviation has a great influence on the luminous efficiency. Therefore, the top-emitting transparent display panel has high requirements for the alignment accuracy of the upper cover and the lower cover, and the process is relatively complicated.

The present application provides an array substrate and a display device, wherein the array substrate is a bottom-emitting OLED array substrate, including a plurality of pixel units, and each pixel unit is divided into a light-emitting area and a light-transmitting area, and the array of the light-emitting area The substrate includes: a substrate, and a driving transistor and a storage capacitor arranged on the substrate, and the display light passes through the storage capacitor and exits. The technical solution of the present application realizes transparent display through the OLED array substrate of the bottom emission structure. The light-emitting area is provided with a storage capacitor that can pass through the display light. Since it is a bottom emission structure, there is no need to set a black matrix on the packaging cover of the array substrate. Furthermore, the pixel units on the array substrate do not need to be precisely aligned with structures such as the black matrix on the package cover. Compared with the existing top-emitting structure to achieve transparent display technology, the array substrate provided by this application can reduce alignment accuracy and simplify craft.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate and a display device. Background technique [0002] With the development of the information society, novel display technologies such as transparent display devices have obtained good user experience and have broad market prospects. However, the transparent display panel and the transparent display device including the transparent display panel have not been commercialized so far because of the competition between the transparency of the transparent display device and the luminous efficiency of the panel. The design of enhancing the transparency of the transparent display panel will be at the expense of reducing the light-emitting area, thereby reducing the luminous efficiency, and vice versa. [0003] In the prior art, in order to improve the transparency, a top emission structure is usually used to make a transparent display panel. Since the upper co...
