Claim 11:
12. A method for manufacturing a display substrate, comprising: forming an optical adjustment structure on a light emitting side of a white OLED display unit, wherein the optical adjustment structure is in a peripheral region of each pixel region, and the optical adjustment structure is configured to absorb light in a first wavelength range or convert light in a first wavelength range into light in a second wavelength range;
wherein an angle, between a line connecting a first peripheral point of the optical adjustment structure and a center of the white OLED display unit and a normal line perpendicular to the base substrate, is greater than a threshold, the threshold ranges from 45 degrees to 60 degrees, the first peripheral point is the point closest to the center of the white OLED display unit on the optical adjustment structure;
in a direction where the center of the white OLED display unit faces the optical adjustment structure, an intensity decrease rate of the light in the first wavelength range is smaller than that of the light in the second wavelength range.
