Embodiment Construction

[0055] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0056] Compared with liquid crystal display panels (English: Liquid Crystal Display, abbreviation: LCD), self-luminous display panels have the advantages of self-luminescence, fast response, wide viewing angle, high brightness, bright colors, power saving and lightness, etc. The next-generation flat-panel display technology is one of the most concerned technologies in the flat-panel display technology. The self-luminous display panel may be an organic light emitting diode (English: Organic Light Emitting Display, abbreviation: OLED) display panel or a quantum dot light emitting diode (English: Quantum Dot Light Emitting Diodes, English: QLED).

Abstract

The invention discloses a pixel definition layer, a color filter film and a manufacturing method thereof, and a self-luminous display panel, belonging to the technical field of display. Each connectedgroove in the pixel definition layer is connected with all sub-pixel regions in a sub-pixel region group corresponding to the connected groove, and each connected groove is connected with a corresponding opening in the side wall of the pixel definition layer so that a color resistance material can be poured into the sub-pixel regions in the corresponding sub-pixel region group through the openingand the connected groove corresponding to the opening to form a color filter film. The pixel definition layer can support the pouring technique to form a color filter film, which reduces the film forming complexity of the color filter film. Furthermore, the color resistance material in each sub-pixel region can be spread evenly in the sub-pixel region by pouring in the embodiment of the invention, so that the film forming uniformity of the color resistance material in the pixel regions is improved, and the display performance of the self-luminous display panel is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a pixel defining layer, a color filter film, a manufacturing method, and a self-luminous display panel. Background technique [0002] Since the self-luminous display panel has an organic light-emitting layer, it can have self-luminous characteristics. Some self-luminous display panels also have a color filter film (English: Color Filter; abbreviation: CF), also known as a color-resist layer, to achieve color display. [0003] In the related art, the formation methods of the color filter film of the self-luminous display panel mainly include vapor deposition technology and inkjet printing technology. Among them, the evaporation technology refers to: the color resist material is evaporated into a molecular state through a specific technology, and the color resist material in the molecular state is hit by a mask plate to form a pixel definition (English: Photo Define Layer, referr...
