A pixel structure, a method for forming the pixel structure, and a display screen are provided. The method includes: providing a substrate for forming an OLED device, the substrate having a first pixel area, a second pixel area, and a third pixel area; and forming a compensation layer on the substrate, the compensation layer having different thicknesses in the first pixel area, the second pixel area, and the third pixel area. In the present disclosure, the compensation layer is formed on the substrate, and the compensation layer has different thicknesses respectively in the first pixel area, the second pixel area and the third pixel area, so that the cavity of the first pixel area, the cavity of the second pixel area, and the cavity of the third pixel area can be individually controlled.

Pixel structure, method for forming the same, and display screen

A shadow mask used for OLED evaporation and a manufacturing method therefor, and an OLED panel manufacturing method. The shadow mask used for OLED evaporation includes: a semiconductor substrate including a front surface and a back surface opposite thereto, a recess penetrating the front surface and the back surface being provided in the semiconductor substrate; and a grid film layer provided on the front surface of the semiconductor substrate. A number of openings arranged in an array are provided in the grid film layer. Each of the openings has an upper portion and a lower portion. A width of the upper portion is greater than a width of the lower portion. The recess exposes the number of openings in the grid film layer and the grid film layer between adjacent openings.
