Abstract

The present application provides a flexible display screen, the flexible display screen includes a substrate and a plurality of sub-pixels arranged on the substrate, each of the sub-pixels is provided with a unit driving circuit, and each of the unit driving circuits includes a Drive transistor and a reset capacitor, each of the drive transistors includes a gate, a channel layer, a source, and a drain, and the reset capacitor includes a first reset electrode and a second reset electrode that are oppositely arranged, and the first reset electrode The electrode is arranged on the side of the gate facing the source and the drain, the second reset electrode is the gate or is electrically connected to the gate, and the flexible display includes a light-transmitting portion and a metal interconnection layer formed in the interconnection region around the light-transmitting portion, the metal interconnection layer is electrically connected to the first reset electrode of the unit driving circuit in the sub-pixel located in the interconnection region .

Description

technical field [0001] The present application relates to the field of flexible displays, in particular to a flexible display screen. Background technique [0002] At present, although the hole-digging screen, which is the mainstream of the market, has increased the screen-to-body ratio, the design of the hole-digging makes the display effect of the screen worse in low grayscale. For example, the horizontal split screen due to the difference in the Array structure at the hole, the mura that appears near the camera hole, also known as O-cut mura, and the color and brightness unevenness caused by poor driving compensation ability at low grayscale. The generation of these situations is related to the voltage compensation of the driver thin film transistor (DTFT). For example, the split screen phenomenon caused by the discontinuity of the initial voltage level caused by digging holes. Contents of the invention [0003] In view of this, the purpose of the present application ...
