Problems solved by technology

[0004] However, the output signal (that is, the scan signal) of the traditional amorphous silicon shift register circuit has poor stability, and it is easily coupled by an external frequency signal to generate excessive noise, resulting in erroneous logic output

Abstract

A display panel of a display device comprises a display region and a non-display region located on the outside of the display region. The display panel comprises a plurality of pixel electrodes, a plurality of scanning lines and a scanning line driver. The plurality of pixel electrodes and the plurality of scanning lines are located in the display region. The scanning line driver is located in the non-display region and comprises a plurality of shifting storage units. Each shifting storage unit comprises an input element used for receiving a starting signal and a control element for restraining noise, wherein the input element or the control element is a bigrid transistor.

Description

technical field [0001] The present invention relates to a display device, in particular to a display device in which a scanning line driving device of a display panel has double gate transistors. Background technique [0002] In recent years, with the vigorous development of semiconductor technology, portable electronic products and flat panel display products are also emerging. Among the types of flat panel displays, Liquid Crystal Display (LCD) has become the mainstream of display products due to its advantages of low voltage operation, no radiation scattering, light weight and small size. [0003] In order to lower the production cost of liquid crystal displays, some manufacturers have directly produced multi-level amorphous silicon shift register units (a-Sishift register) on glass substrates through amorphous silicon technology, thereby reducing the production cost of liquid crystal displays. . [0004] However, the output signal (that is, the scanning signal) of the ...
