Problems solved by technology

Although the thin film transistor is not conducting, the capacitive coupling between the data line and the pixel electrode will also affect the holding state of the pixels D1-Dn in the rows G2-Gm, thus causing vertical crosstalk on the display screen
Moreover, the above problems are exacerbated when the resolution is higher

Abstract

The invention discloses a display substrate and a preparation method, a display panel and a display device. The display substrate includes a substrate provided with a plurality of first film transistors, a plurality of gate lines and a plurality of data lines. Each data line includes at least two data line segments. Second film transistors are arranged between the adjacent data line segment. A first electrode of each second film transistor is connected with one data line segment of one data line while a second electrode of each second film transistor is connected with the other data line segment of said data line, so that data signals are transmitted downward to the next stage under the control of the second film transistors. Therefore, capacitive coupling between the data lines and the pixel electrodes are avoided, vertical crosstalk is eliminated completely and non-uniformity of luminance of a head end and a tail end is improved.
