Abstract

The embodiment of the invention discloses a display panel and a production method thereof. The display panel comprises a first display area and a second display area, the display panel further comprises a substrate and a pixel definition layer arranged on one side of the substrate, and the pixel definition layer is provided with pixel openings. A cathode suppression layer made of a light-transmitting material is arranged between every two adjacent pixel openings in the first display area; and the area of the orthographic projection of the cathode suppression layer on the substrate is smaller than or equal to 0.95 times of the area of the first display area. By arranging the cathode suppression layer, when the cathode layer is formed by adopting a whole-surface evaporation process, the cathode layer deposited on the cathode suppression layer is thinner or no cathode layer is deposited so that the light transmittance of the light-transmitting area is greatly improved, and meanwhile, the area ratio of the cathode suppression layer to the first display area is set; and the light transmittance of the first display area is improved as much as possible on the premise that normal display of the first display area is guaranteed.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a manufacturing method thereof. Background technique [0002] OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display technology has attracted more and more attention from scientific researchers, and is widely used in display fields such as mobile phones, tablets, and TVs. With the rapid development of display devices, users The screen-to-body ratio requirements of display devices are getting higher and higher, making large-size and high-resolution comprehensive display devices a future development direction. [0003] In the existing technology, in order to increase the screen-to-body ratio as much as possible, optical components such as the front camera and face recognition are usually placed under the screen. However, in the existing OLED full-scale display device, the cathode is set on the entire surface. , while the transmitta...
