Problems solved by technology

However, the GIA circuit is prone to instability due to the influence of the environment. For example, when the GIA circuit operates in a low temperature environment, the threshold voltage of the transistor (such as TFT) in the GIA circuit will drift and the circuit will not work.
Therefore, existing GIA circuits cannot be applied to fields with high requirements on circuit reliability and stability, such as the field of vehicle systems

Abstract

The present invention discloses a display device and a driving method. The display device comprises a display panel and a source driving circuit. The display panel is composed of a plurality of pixel units, a plurality of scanning lines, a plurality of data lines and a plurality of gate driving circuits. Each row of the pixel units is correspondingly connected with one scanning line. Each column of the pixel units is correspondingly connected with one data line. The plurality of gate driving circuits are used for supplying first driving signals to the plurality of scanning lines. The source driving circuit is used for supplying second driving signals to the plurality of data lines. Each scanning line is connected with two gate driving circuits. Compared with the prior art, in the low-temperature condition, each pixel unit of the display device can be simultaneously driven by a circuit better in driving capability. Therefore, the narrow-frame effect is realized based on the integrated gate driving circuit technology, while the defect that transistors in the display device are not stable and low in reliability is overcome at the same time.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device and a driving method. Background technique [0002] At present, Liquid Crystal Display (LCD) has many advantages such as thinness, energy saving, and no radiation, and is widely used in products such as notebook computers, desktop computers, video recorders, smart TVs, mobile terminals, and personal digital processors. superior. Taking liquid crystal display devices applied to mobile phones as an example, under the premise of a certain size of mobile phones, users generally hope that the screen can be as large as possible, so how to realize the narrow frame of the display device has become the direction of extensive research and the goal pursued by the industry. [0003] Taking a thin film transistor (Thin Film Transistor, TFT) liquid crystal display device as an example, it includes a liquid crystal display panel, a gate drive circuit (gate drive circu...
