The invention provides a display panel, a driving method and a display device. A pressure detection electrode is arranged on a first substrate or a second substrate, the pressure detection electrode is a block electrode arranged in a matrix, a backlight module and a pressure sensing electrode are arranged on a back light, and the backlight module is located between the pressure sensing electrode and the second substrate; the pressure detection electrode and the pressure sensing electrode form a pressure sensing capacitor, in a pressure detection phase, a pressure detection signal is input to the pressure detection electrode, a first reference signal is input to all pressure sensing electrodes, a pressure sensing signal output by the pressure detection electrode is received to detect the pressure of the display panel, so that the display panel and the display device provided by the invention can detect the touch pressure, and thus the functions of the liquid crystal display panel are enriched.
Description
technical field [0001] The present invention relates to the technical field of liquid crystal display, and more specifically, to a display panel, a driving method and a display device. Background technique [0002] Due to the advantages of low radiation, small size and low power consumption, liquid crystal display devices have been widely used in people's life and work, such as notebook computers, personal digital assistants, flat-screen TVs, mobile phones and other electronic devices. [0003] Such as figure 1 As shown, the existing liquid crystal display panel includes a color filter substrate 11, an array substrate 12 and a backlight plate 13, wherein a liquid crystal layer 14 is arranged between the color filter substrate and the array substrate, and the array substrate 12 is located between the liquid crystal layer 14 and the back plate 13. between. The backlight panel is generally provided with a light source, a light guide plate, and an optical film layer on the lig...
