Abstract

The invention discloses a demultiplexer and a display panel with the demultiplexer. The demultiplexer includes a plurality of demultiplexing units, and each demultiplexing unit includes two first-type thin film transistors with a common source, and between each adjacent two demultiplexing units, there is also There are two second-type thin film transistors. The present invention improves the space utilization ratio of the demultiplexer by arranging two second-type thin film transistors between every two adjacent demultiplexing units, thereby reducing the size of the demultiplexer. The application of the demultiplexer to the LTPS display panel is beneficial to the realization of the narrow frame of the LTPS display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a demultiplexer and a display panel with the demultiplexer. Background technique [0002] Throughout the development of the small and medium-sized display panel market, it is an inevitable trend for display panels to achieve high resolution and narrow bezels. Among various small and medium-sized display panels, the Low Temperature Poly-silicon (LTPS) display panel has gradually become a mainstream product in the small and medium-sized display panel market due to its advantages of high resolution. [0003] In the LTPS display panel, a demux is often used to divide one data output from the driver chip into multiple data. The demux is mainly composed of thin film transistors (Thin Film Transistor, TFT). figure 1 A schematic diagram of the layout of thin film transistors in an existing demultiplexer, such as figure 1 As shown, the demultiplexer consists of 2 demultiplexing units, ...
