Problems solved by technology

[0004] In the existing array substrate, since only part of the drain of the TFT overlaps with the pixel electrode, in this way, when the grayscale signal loaded by the data line passes through the TFT to charge the pixel electrode, it can only charge the pixel electrode from one point on the edge of the pixel electrode. , that is, the position where the pixel electrode is electrically connected to the drain in the TFT starts to charge the pixel electrode, which will lead to low charging efficiency for the pixel electrode, thereby affecting the response speed of the flat panel display

Abstract

The invention discloses an array substrate and a display device. The array substrate comprises a substrate body, a plurality of thin-film transistors and a plurality of pixel electrodes, the thin-film transistors and the pixel electrodes are located on the array substrate, and the thin-film transistors correspond to the pixel electrodes one to one. Because the orthographic projection, on the substrate body, of each thin-film transistor is completely located within the orthographic projection, on the substrate body, of the corresponding pixel electrode, when gray scale signals loaded on data lines charge the pixel electrodes through the thin-film transistors, charging can be carried out from the interior to the periphery of each pixel electrode, the pixel electrodes can be fast charged, the charging efficiency of the pixel electrodes can be improved, and the response speed of a flat-panel display can be increased.
