Embodiment Construction

[0047] An embodiment of the present invention proposes a display, in which the display panel can further feed back the scanning signal passing through the display area to the gate driving circuit, so that the gate driving circuit can correct The scanning signal output to the display panel is used to compensate the gray scale difference caused by the RC load of the gate line between the pixels of each row, so that the picture quality of the display can be effectively improved. In order to make the content of the present disclosure more comprehensible, the following specific embodiments are taken as examples in which the present disclosure can actually be implemented. In addition, wherever possible, elements / components / steps using the same reference numerals in the drawings and embodiments represent the same or similar parts.

Abstract

A display includes a display panel and a driving chip. The display panel has a plurality of gate lines and a plurality of pixels arranged in an array, wherein the gate lines are respectively coupled to each row of pixels. The driver chip is coupled to the display panel and disposed on one side of the display panel, and is used to control the image display of the display panel. The driving chip includes a gate driving circuit, wherein the gate driving circuit includes a gate driving unit and a compensation unit. The gate driving unit is used for providing a plurality of scan signals to one end of the gate lines on the display panel to drive pixels on the gate lines. The compensation unit receives the scanning signal provided by the gate driving unit from the other end of the gate line, and compensates the waveform of the scanning signal provided by the gate driving unit according to the scanning signal received from the other end of the gate line and the reference signal.

Description

technical field [0001] The invention relates to a display, and in particular to a display capable of correcting the waveform of a scanning signal. Background technique [0002] In the field of display driving technology, in order to increase the display area of ​​the display panel and make the display more miniaturized, manufacturers have developed the integration of gate driver and source driver. The technology integrated in the same driver chip. [0003] Under the framework of integrating the gate drive circuit and the source drive circuit into a driver chip, since the driver chip is arranged on one side of the display panel, the display panel needs to use a fanout line structure to arrange the gate lines , so as to connect the driving chip and each row of pixels of the display panel through the gate line. In addition, in order to reduce the left and right borders of the display panel, this type of display panel is usually designed with a double-layer wiring structure. ...
