Abstract

The present disclosure provides a voltage applying circuit, a liquid crystal display device, and a method for applying a common voltage signal to a liquid crystal display panel. The voltage applying circuit includes: a control module, configured to output a control signal based on a gate low voltage signal of the display panel; and a switch module, configured to apply the common voltage signal to the liquid crystal display panel in response to the control signal.

Description

Technical field [0001] The present invention relates to the field of display technology, and in particular, to a voltage application circuit, a liquid crystal display device, and a method for applying a common voltage signal to a liquid crystal display panel. Background technique [0002] Liquid crystal display is one of the most widely used flat panel displays. A liquid crystal display generally includes a liquid crystal layer disposed between two substrates, and displays an image by adjusting the state of the liquid crystal layer according to the magnitude of an electric field applied to the liquid crystal layer, thereby adjusting light transmission. [0003] However, there is a "flashing white" problem when the LCD monitor is turned on. [0004] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present invention, and therefore may include information that does not constitute the ...
