The invention relates to a backlight drive circuit, a display terminal and a display driving method.The backlight drive circuit comprises a first switch assembly, a second switch assembly, an energy storage assembly, a driving assembly, a detection assembly, a light-emitting assembly and an interface assembly, and the first switch assembly is electrically connected with a scanning line, a data line and the driving assembly; the second switch assembly is electrically connected with the power line, the second control line and the driving assembly. The energy storage assembly is electrically connected with the first switch assembly, the driving assembly and the detection assembly to form an internal node together; the driving assembly is electrically connected with the second switch assembly, the light-emitting assembly and the internal node. The detection assembly is electrically connected with the first control line, the internal node and the detection line. By arranging the second switch assembly and the detection assembly, the threshold voltage of the first switch assembly can be compensated, the stability of the driving current on the driving assembly is improved, the light emitting quality of the display panel is improved, the occupied space is small, and the display panel is simple and convenient.
Description
technical field [0001] The present application relates to the field of display technology, in particular to a backlight driving circuit, a display terminal and a display driving method. Background technique [0002] Micro LED (ie, Micro LED) display technology refers to a display technology that uses self-illuminating micron-scale LEDs as light-emitting pixel units and assembles them on a driving panel to form a high-density LED array. Compared with the current liquid crystal display (Liquid Crystal Display, LCD) technology and organic light-emitting diode (Organic Light-Emitting Diode, OLED) display technology, the display panel using Micro LED display technology has fast response, high color gamut, high PPI, and low energy consumption. Consumption and other advantages. Therefore, the development of Micro LED display technology has become one of the hot spots of future display technology. However, Micro-LED technology has many difficulties and complex technologies, especi...
