Abstract

The invention provides a method and device for preparing a planarization layer, a display screen and a terminal. The method comprises the following steps: based on the slope of a bending region, determining a compensation angle of color deviation compensation for the bending region; according to the determined compensation angle, calculating the thickness of the planarization layer in the bendingregion; and according to the obtained thickness of the planarization layer in the bending region, preparing the planarization layer, wherein the thickness of the planarization layer in the bending region is larger than the thickness of the planarization layer in a normal region. The method relieves the problem of color deviation caused by the bending region of the display screen and improves the product yield rate of the display screen.

Description

technical field [0001] This article relates to but not limited to touch screen technology, especially a method, device, display screen and terminal for preparing a planarization layer. Background technique [0002] Organic light-emitting display (OLED, Organic Light Emitting Diode) is one of the hot spots in the field of display screen research at present, and various display manufacturers have also invested a lot of material resources and manpower in Active Matrix Organic Light Emitting Diode (AMOLED, Active Matrix Organic Light Emitting Diode) display. In the production of screens; compared with the thin film transistor liquid crystal display (TFTLD, Thin Film Transistor Liquid Crystal Display) in the related technology, AMOLED has faster response speed, higher contrast ratio, wider viewing angle and lower energy consumption and other advantages. With the development of OLED display technology, people are not satisfied with 2D (the industry standard of display screen) dis...
