Abstract

The invention provides a driving method of a display substrate, the display substrate and a display device. The display substrate comprises a substrate body and one or more discrete camera units arranged on one side of the substrate body. Each camera unit comprises one or more pixel units arranged on one side of the underlayer substrate, and a first electrode, a liquid micro lens and a second electrode which are stacked on one side, deviating from the underlayer substrate, of the one or more pixel units, and the first electrode and the second electrode are used for forming a driving voltage applied to the liquid micro lens; the liquid micro lens is used for changing the focal length of the liquid micro lens when the driving voltage changes, so that the display substrate works in a displaystate or a camera shooting state; each pixel unit comprises a photosensitive unit and a light-emitting unit, and the photosensitive unit is used for carrying out photoelectric conversion on light emitted from the liquid micro lens. The liquid micro lens and the photosensitive unit are integrated in the display substrate, the shooting function can be achieved, the normal display function can also be achieved, and the display device is light and thin.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a method for driving a display substrate, a display substrate and a display device. Background technique [0002] With the improvement of people's aesthetics, full-screen display will become the development trend of mobile phone screens in the future. In recent years, full-screen forms such as lifting cameras, Qi Liu Hai, and water drop screens are all pursuing beautiful terminal shapes. [0003] Existing full-screen products all need to install a front-facing camera on the screen, and the installation of the camera makes the display device relatively thick. Contents of the invention [0004] The invention provides a method for driving a display substrate, a display substrate and a display device, so as to reduce the weight and thickness of the display device. [0005] In order to solve the above problems, the present invention discloses a display substrate, which in...
