Display background and display background control methods, and display devices

Abstract

The design refers to the display platform and the method of controlling the display platform, and the display device. The display platform (100) consists of pixel units (20) and pixel circuits (30). The pixel units (20) are divided into groups, and each pixel circuit (30) is used to control the corresponding group of pixel units (20). Each pixel circuit (30) includes a control circuit (31), a data recording circuit (32), a storage circuit (33), a sensor circuit (34) and a light-emitting control circuit (35). The luminescence control circuit (35) is connected to the luminescence element of the corresponding pixel unit group (20), and the luminescence control circuit (35) is configured to, in response to at least two luminescence control signals, supply control current to the luminescence elements of the pixel units (20) in the corresponding pixel unit group (20) at different times. The pixel circuits (30) in the display background (100) achieve capacitive multiplexing. This can increase the surface area of ​​the capacitor and facilitate the maintenance of its voltage.
