a display device

Abstract

The present invention discloses a display device. The display device comprises a display panel; the display panel includes a plurality of pixel units arranged in an array, a plurality of scanning lines and a plurality of stages of gate driving circuits; each row of pixel units is correspondingly connected with one scanning line; the plurality of stages of gate driving circuits are used for providing gate driving signals for the plurality of scanning lines; and the gate driving circuit includes a transfer module, a gate output module and a gate noise reduction module. According to the display device provided by the invention, gate driving signals are not directly involved in the function realization of the transfer modules, so that the change of gate load does not affect transferred signals; when the sizes of the components of the gate output modules are adjusted, the influence of the adjustment on the transferred signals is negligible; and the parameters of the transfer modules at each stage can be shared, and therefore, the complexity of circuit design is reduced, and reliability is improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a display device. Background technique [0002] With the development of science and technology, people's demand for screen display is more and more diversified. People no longer only meet the conventional performance indicators such as large size and high definition of the display panel, but have higher requirements for the appearance of the display panel. . [0003] At present, the emergence of special-shaped display panels not only makes the display effect more diversified, but also improves the limitation of the single rectangular structure of the display panel. The application of shaped display panels has become more and more widespread, and has been successfully applied to wearable electronic devices such as watches, glasses or smart bracelets. The special-shaped display panel usually has a special-shaped display area, such as a circle, a polygon or even a s...

AI Technical Summary

Problems solved by technology

The special-shaped display panel usually has a special-shaped display area, such as a circle, a polygon, or even a shape with cut edges. The edges are irregularly shaped, which will cause the edge pixel units of the display panel to be cut unevenly, so that the area of ​​the pixel units is different. Then there will be uneven color

[0004] In the process of realizing the present invention, the inventor found that the prior art has the following problems: in the integrated gate driver circuit (GIA, Gate Driver In Array) scheme of the special-shaped display panel, the gate loads of different regions of the special-shaped display panel are very different. Large, the parameters of all stages of GIA are shared, it is difficult to ensure the optimization of signal output in all areas, and the abnormal output of local circuits will cause the failure of the entire circuit; according to the gate load partition, reset the thin film transistor (ThinFilm Transistor, TFT) of all stages of GIA , capacitance parameters, can achieve very good results, but this method increases the design parameters and increases the design complexity
