Abstract

The present application provides a display panel, the display panel has a function additional area, the display panel includes a base substrate, an array layer disposed on the base substrate, a light-emitting device layer disposed on the array layer, an encapsulation layer covering the light emitting device layer and a touch control layer disposed on the encapsulation layer; an opening area is provided around the function additional area at the edge position of the function additional area, and an opening area is arranged at the opening area There are openings extending through the array layer and extending to the surface of the base substrate, and the openings are filled with a light blocking layer. The light blocking layer can be used to fill the cracks on the base substrate and play a role of flattening, so as to prevent the cracks from causing uneven depth of the touch layer when forming the touch layer. At the same time, the light blocking layer can prevent light leakage at the opening. conditions, so as to avoid light leakage from adversely affecting the performance of the OLED device.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a display panel. Background technique [0002] Narrow bezel or even bezel-less screens have become the mainstream direction of small-sized mobile phones in the current market. The realization of narrow-bezel design of small-sized display panels to achieve a larger screen ratio is also the direction that the industry has been striving for. [0003] A display panel generally includes a stacked substrate, an array layer, a light-emitting device layer, an encapsulation layer, and a touch layer, and electronic components such as a front camera are generally placed in the upper boundary area of ​​the display panel. In order to reduce the upper boundary area, there are The industry players place the camera under the screen, and open the light-transmitting hole in the area where the camera is placed, that is, remove the light-shielding film layer in the camera area, such as...
