Abstract

The invention provides a display substrate, and a preparation method thereof and a display device. The display substrate comprises a circuit layer arranged on a substrate, a light-emitting structure layer and a photoelectric structure layer, the light-emitting structure layer and the photoelectric structure layer are arranged on the side, away from the substrate, of the circuit layer, the circuit layer comprises at least one impurity absorption layer and at least one transistor, and the transistor comprises an active layer. At least one insulating layer is arranged between the impurity absorption layer and the active layer; and the atomic ratio of the silicon element to the nitrogen element in the impurity absorption layer is 1:5-1:35. By arranging the impurity absorption layer, the display substrate is effectively prevented from generating a large number of bright spots, the yield is increased, and the display effect is improved.

Description

technical field [0001] The present disclosure relates to but is not limited to the field of display technology, especially to a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] Organic Light Emitting Diode (OLED) is an active light-emitting display device, which has the advantages of self-illumination, wide viewing angle, high contrast, low power consumption, high response speed, light and thin, bendable and low cost. With the continuous development of display technology, a display device using OLED as a light-emitting device and signal-controlled by a Thin Film Transistor (TFT for short) has become a mainstream product in the display field. [0003] Although OLED display devices have been widely used, there are still many technical problems, such as compensation technology. Compensation technology is mainly used to overcome defects such as uneven brightness and afterimage, so as to improve the display quality of the dis...
