Problems solved by technology

[0003] In the display panel, due to the differences in the turn-on voltages of red sub-pixels, green sub-pixels and blue sub-pixels, when a sub-pixel with a high turn-on voltage is turned on, the current flows laterally through the carrier layer, thereby slightly lighting up the sub-pixel with a low turn-on voltage. sub-pixels, resulting in low-gray-scale color cast in the display screen and abnormal display

Abstract

Embodiments of the present invention provide a method for manufacturing a display panel, a display panel, and a display device. The method for manufacturing a display panel includes: forming a pixel definition layer on a substrate, where the pixel definition layer includes a body portion and a plurality of pixel openings distributed in an array; Functional groups are formed on the surface of the pixel definition layer, and the pixel definition layer is treated with plasma. The plasma includes at least one redox gas to form functional groups capable of inducing the aggregation of organic molecules on the surface of the pixel definition layer; formed on the side of the pixel definition layer away from the substrate carrier layer. The embodiments of the present invention can reduce the lateral current, avoid the low grayscale color shift of the display screen caused by the current crosstalk, and improve the display effect of the display panel.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to a method for manufacturing a display panel, a display panel and a display device. Background technique [0002] Flat display panels such as Liquid Crystal Display (LCD) panels, Organic Light Emitting Display (OLED) panels, and display panels using Light Emitting Diode (LED) devices have high image quality and low power consumption. , thin body and wide application range, etc., and are widely used in various consumer electronics products such as mobile phones, televisions, personal digital assistants, digital cameras, notebook computers, and desktop computers, and become the mainstream of display devices. [0003] In the display panel, due to the differences in the turn-on voltages of red sub-pixels, green sub-pixels and blue sub-pixels, when a sub-pixel with a high turn-on voltage is turned on, the current flows laterally through the carrier layer, thereby slightl...
