Display substrate, manufacturing method thereof, and display device

Abstract

A display substrate, a manufacturing method thereof, and a display device are disclosed. The display substrate includes a substrate, and a plurality of sub-pixels, a plurality of columns of power lines and data lines which are disposed on the substrate. Each sub-pixel includes: a driving circuit. The driving circuit includes a transistor and a capacitor. The capacitor includes a first electrode plate and a second electrode plate opposite to each other. The active layer of the transistor is located on a side of the second electrode plate of the capacitor close to the substrate. The power linesare located on a side of the second electrode plate of the capacitor away from the substrate. For each sub-pixel, the power lines are connected to the second electrode plate of the capacitor and the active layer of the transistor. The second electrode plate of the capacitor of each sub-pixel is connected to the second electrode of the capacitor of an adjacent sub-pixel located in the same row. Theactive layer of the transistor of each sub-pixel is connected to the active layer of the transistor of another adjacent sub-pixel located in the same row. The display substrate can reduce the load ofthe data lines, thereby reducing the power consumption of the display substrate and shortening the writing time of a data signal.

Description

technical field [0001] This article relates to the field of display technology, in particular to a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Device, referred to as OLED) display substrate is a display substrate different from traditional liquid crystal display (Liquid Crystal Display, referred to as LCD), with active light, good temperature characteristics, low power consumption, responsive Fast, bendable, ultra-thin and low cost. Therefore, it has become one of the important development discoveries of the new generation display device, and has received more and more attention. [0003] In order to realize the high-frequency driving of the OLED display substrate, an OLED display substrate with double data lines is proposed in the related art, that is, the same column of sub-pixels is connected to two data lines. However, in the OLED display substrate in the rel...

AI Technical Summary

Problems solved by technology

However, in the OLED display substrate in the related art, the distance between the power connection line and the data line respectively connected to the power line and the same row of sub-pixels is relatively short, so that the load on the data line is relatively large, which in turn leads to a large power consumption of the OLED display substrate. And the writing time of the data signal provided by the data line is longer
