Abstract

The invention relates to an MLED display panel and terminal equipment, the MLED display panel comprises a plurality of pixel driving circuits, at least one pixel driving circuit comprises a first transistor, a second transistor, a capacitor and a first light emitting assembly, a first port of the first transistor is electrically connected with a first port of the second transistor and one end of the capacitor; a second port of the first transistor is electrically connected with a third port of the second transistor and the other end of the capacitor respectively; a second port of the second transistor is electrically connected with one end of the first light-emitting component; a third port of the first transistor is electrically connected with a first power supply voltage, and the other end of the first light-emitting assembly is electrically connected with a second power supply voltage. According to the pixel driving circuit, the second transistor is arranged in the pixel driving circuit, so that the difference between driving currents in different directions can be reduced, the symmetry and stability of the circuit are improved, the current power effect of a driving device is reduced, the power consumption is further reduced, and the driving mode is simplified.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to an MLED display panel and a terminal device. Background technique [0002] MLED includes Mini-LED display technology and Micro-LED display technology. Mini-LED display technology and Micro-LED display technology are widely regarded as the next generation display technology after TFT-LCD display technology, but they have encountered some very difficult technical bottlenecks, such as the stability of driving circuits, mass transfer methods and yields. [0003] Specifically, with regard to the stability of the driving circuit, the stability of the thin film transistor (Thin Film Transistor, TFT) device is mainly concerned. In TFT-LCD products, the stability requirements of the device are not high. The reasons include: first, the function of the TFT device is to write the data-driven voltage signal into the pixel (ie, Pixel) through the addressing switch action, whi...
