Embodiment Construction

[0026] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described through implementation with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are the embodiment of the present invention. Some, but not all, embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] It is known that the power consumption of the data driving circuit is determined by the size of the demux switch and the number of charge and discharge times. Obviously, reducing the size of the demux switch and the number of times of charge and discharge can achieve the purpose of reducing power consumption. However, reducing the size of the demu...

Abstract

An embodiment of the invention discloses a display panel, a data driving circuit thereof, and a display device. The data driving circuit comprises at least one switching circuit. The switching circuit comprises two switching devices. A first switching device transmits a data signal which is received from a data lead wire to a data wire. A second switching device transmits the data signal which is received from the data lead wire to the data wire. When the data signal is in a forward data state, a first control wire starts the first switching device and simultaneously a second control wire starts the second switching device. When the data signal is in a reverse data state, the first control wire starts the first switching device and simultaneously the second control wire stops the second switching device. According to the display panel, the data driving circuit and the display device, the data driving circuit ensures no positive frame charging capability loss of a display panel through driving by a large-size switching circuit, and furthermore ensures negative frame charging capability of the display panel through a small-size switching circuit, thereby realizing an effect of reducing power consumption of the display panel.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular to a display panel, a data driving circuit thereof, and a display device. Background technique [0002] Liquid crystal display is the mainstream product in the field of liquid crystal display now. The display effects such as brightness, contrast, color and viewing angle of the liquid crystal display are mainly determined by the liquid crystal display panel, and 80% of the cost of the liquid crystal display is also mainly concentrated in the liquid crystal display panel. Therefore, the liquid crystal display The display panel is the main factor that determines the quality and cost of an LCD monitor. The liquid crystal display panel can use the data driving circuit to reduce the cost of the driving chip to achieve the purpose of reducing the cost of the panel. The data driving circuit controls one data lead to drive at least two data lines, and the polarity of the data...
