Abstract

The invention provides a Mura compensation circuit, a Mura compensation method, a driving circuit and a display device. The Mura compensation circuit comprises a vertical Mura compensation unit and / or a horizontal Mura compensation unit, wherein the vertical Mura compensation unit provides corresponding gamma voltages for a vertical block-shaped Mura area and a vertical non-Mura area of a display panel to compensate a vertical Mura phenomenon; and the horizontal Mura compensation unit provides corresponding gate driving signals and / or corresponding charging and discharging control signals to a horizontal block-shaped Mura area and a horizontal non-Mura area of the display panel to compensate a horizontal Mura phenomenon. Thus, different areas of the display panel can have the same display effects, the drop of the display quality caused by impedance differences at different positions in the display panel can be improved, the picture quality is enhanced, and wide promotion and wide use can be facilitated.

Description

technical field [0001] The invention relates to the technical field of Mura compensation, in particular to a Mura compensation circuit and method, a driving circuit and a display device. Background technique [0002] Compared with traditional cathode ray tube displays, liquid crystal displays have the advantages of light and thin body, low power consumption, no radiation, and long service life. Because of the above-mentioned advantages, liquid crystal displays, as a flat panel display device, are widely used in electronic products such as mobile phones, computers, televisions, and digital cameras, and have occupied a dominant position in the flat panel display market. [0003] With the rapid development of flat panel display technology, in order to reduce production costs, the design of large-scale liquid crystal display panels will use a driver IC (Integrated Circuit, integrated circuit) that includes more channels, or use a dual-gate (DualGate) / tri-state gate ( TripleGate...
