Abstract

The invention provides a Demux circuit structure and a display panel, the Demux circuit structure comprises a Demux connecting line and a plurality of groups of thin film transistors, and each group of thin film transistors comprises more than two thin film transistors; the thin film transistor comprises gate metal, an insulating layer, a semiconductor layer, source metal and drain metal, the insulating layer is arranged on the gate metal and the Demux connecting line, and the semiconductor layer is arranged on the insulating layer and located in the gate region; the Demux connecting line is connected with the gate metal of the thin film transistor; the multiple groups of thin film transistors are arranged in rows and columns; different thin film transistors in each group are located in different rows, grid metal of the thin film transistors in the same row between adjacent groups is connected through the Demux connecting line, and a connecting line of source metal and drain metal crosses over the Demux connecting line to be connected to the outer side of the Demux circuit structure. According to the technical scheme, the screen-to-body ratio of the screen is increased, and the Cgdparasitic capacitance on the Demux circuit is reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a Demux circuit structure and a display panel. Background technique [0002] For the display panel, due to the existence of peripheral circuits and traces of the display panel, there is bound to be a border of a certain width around the display panel. How to reduce the size of the surrounding borders and increase the screen-to-body ratio of the screen is a hot topic. When solving this kind of problem, there are two main solutions: the first method is to use a flexible OLED screen, and fold the borders around the panel behind the screen, so that the mobile phone module can achieve a 100% appearance. A screen-to-body ratio phenomenon. This method just hides the surrounding borders behind, without actually making the surrounding borders of the panel smaller. The second method improves the screen-to-body ratio of the screen to a certain extent by changing the design of peripheral...
