Embodiment Construction

[0024] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments that the present application can be used to implement. The directional terms mentioned in this application, such as [top], [bottom], [front], [back], [left], [right], [inside], [outside], [side], etc., are for reference only The orientation of the attached schema. Therefore, the directional terms used are used to illustrate and understand the application, but not to limit the application. In the figures, structurally similar elements are denoted by the same reference numerals.

[0025] The present application aims at the technical problem that the existing liquid crystal display device has the problem that the Gamma voltage changes during the transmission process and the Gamma voltage drop is relatively large, which leads to uneven display of the liquid crystal panel screen. This embodiment can solve this defect.

Abstract

The invention provides a driving circuit and a liquid crystal display device. The driving circuit is used for driving the liquid crystal panel, and comprises at least two liquid crystal driving chipswhich are arranged in a one-dimensional array form and are used for receiving an original Gamma voltage; and a time sequence control chip which is used for receiving the original Gamma voltage transmitted by the liquid crystal driving chips and outputting a Gamma voltage correction parameter to the liquid crystal driving chips. The liquid crystal driving chips perform compensation correction on the original Gamma voltage according to the Gamma voltage correction parameters, so that the Gamma voltage values of the liquid crystal driving chips are the same, and the problem of non-uniform picturedisplay of the liquid crystal panel is solved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a driving circuit and a liquid crystal display device. Background technique [0002] As a common electronic device, a liquid crystal display (LCD) is favored by users because of its low power consumption, small size, and light weight. With consumption upgrades and technological developments, the size of LCD panels is getting larger and larger, so more and more LCD driver chips need to be installed. At this time, the Gamma voltage generation module is required to transmit the generated Gamma voltage to each liquid crystal driver chip, but because the distance between each liquid crystal driver chip and the Gamma voltage generation module is different, the voltage changes during the Gamma voltage transmission process, and the Gamma voltage Large voltage drop and other problems, resulting in uneven display of the LCD panel. [0003] Therefore, there are defects in the p...
