Embodiment Construction

[0036] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments in which the present invention can be practiced.

[0037] Certain terms are used in the description and claims of the present invention to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component.

[0038] "Includes" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" here includes any direct and indirect electrical connection means. Therefore, if it is described in this specification that the first element is coupled to the second element, it means that the first element can be directly electrically connected to the second element. element, or indirectly electrically connected to the second element through other elements or connection means. ...

Abstract

The invention discloses a gate driving circuit of a display, which is characterized in that at least one transistor is connected between a transistor providing a high potential node and a reference voltage signal input end in series, and a preset high potential is provided between the transistor that is connected to the node and an input end of the at least one transistor. For example, the drive voltage of a gate line corresponding to the gate is fed into the input end, and the preset high potential provided can reduce the potential difference between the source and the drain of the transistor, so that current leakage of the transistor can be reduced, and the stability of the drive voltage of the gate electrode driving circuit is further improved so as to improve the reliability of the gate electrode driving circuit.

Description

【Technical field】 [0001] The invention relates to a gate drive circuit of a display, in particular to a gate drive circuit of a display which can effectively reduce the leakage current of a transistor. 【Background technique】 [0002] A liquid crystal display (LCD) uses an electric field to control liquid crystal molecules with dielectric anisotropy to change light penetration and display images accordingly. A liquid crystal display generally includes a display panel with pixels arranged in a matrix and a driving circuit for driving the display panel. [0003] The above-mentioned driving circuit is generally divided into a source driving circuit and a gate driving circuit. The source driving circuit converts the input data into a data signal, and the gate driving circuit generates a scanning signal for driving pixels to display the corresponding input data. image of the data. The source driving circuit and the gate driving circuit can operate according to the timing determi...
