Embodiment Construction

[0037] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Apparently, the described embodiments are only some of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of this application.

[0038] see figure 1 , figure 1 It is the film layer structure diagram after cutting of the existing display panel. In the existing OLED display panel, in order to reduce the thickness of the display panel, it can use the depolarizer technology to make the OLED panel, that is, replace the existing polarizer with the color resist layer and the black matrix layer, and in order to ensure the flatness of the product, It usually coats a first flat layer on the color filter layer, an...

Abstract

The invention discloses a display panel, a display module and a mobile terminal. The display panel comprises a substrate, a light-emitting device layer arranged on the substrate and a color film layer arranged on the light-emitting device layer, the substrate comprises a first boundary close to one side of a cutting face of the display panel, and a second boundary close to one side of the cutting face of the display panel is arranged on the first boundary in the top view direction of the display panel. According to the display panel, the distance between the film boundary, close to one side of the cutting face, of a film in the direction from the substrate to the color film layer in the display panel and the first boundary is gradually increased, and the included angle between the cutting face and the substrate is an obtuse angle. The carbon chips generated in the cutting process of the display panel are accumulated on the side close to the substrate, the carbon chips are prevented from remaining on the side close to the substrate, and the cleanliness of products is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel, a display module, and a mobile terminal. Background technique [0002] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) panels have the advantages of thinness, large viewing angle and power saving, and will become the mainstream of future development. [0003] In the existing OLED display panel, in order to reduce the thickness of the display panel, the OLED panel can be manufactured by using a depolarizer technology, that is, the existing polarizer is replaced by a color resist layer and a black matrix layer. When cutting the panel, since the black matrix around the display panel needs to be cut by laser, the high temperature of the laser will lead to carbonization of the black matrix, and the carbonized carbon dust may remain in the edge gap of the display panel, affecting the display panel. cleanliness. [0004] Therefore, there i...
