Abstract

The invention discloses an organic light-emitting diode OLED display substrate and a manufacturing method thereof, a display panel and a display device. A substrate and pixel limitation layers arranged on the substrate are included. Each pixel limitation layer has an opening limiting the light emitting area of an organic light emitting component. The pixel limitation layers have at least two thicknesses, and the heights of the openings where the two adjacent organic light emitting components with different colors are located are different. PPI can be increased and the risk of color mixing is avoided.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic light emitting diode (OLED) display substrate, a preparation method, a display panel and a display device. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) display is recognized by the industry as the successor to liquid crystal due to its many advantages such as thinness, active light emission, fast response, wide viewing angle, rich colors, high brightness, low power consumption, and high and low temperature resistance. The third-generation display technology after the display (Liquid Crystal Display, LCD) can be widely used in terminal products such as smart phones, tablet computers, and televisions. [0003] The number of pixels per inch (Pixel Per Inch, PPI) is getting higher and higher, which has become the development direction of display technology. The higher the PPI, the richer the picture details. There are ma...
