Abstract

The application discloses a Micro / Mini LED display device and a driving method and a display equipment thereof. The display device comprises a glass substrate, an active matrix driving backboard and a Micro / Mini LED light emitting array. The active matrix driving backboard is integrated on the glass substrate and comprises a plurality of pixel driving circuits arranged in an array. The Micro / Mini LED light emitting array is arranged on the active matrix driving backboard, and each light emitting unit is independently driven by a corresponding pixel driving circuit. Each pixel driving circuit comprises at least a switching transistor, a driving transistor and a storage capacitor. The switching transistor is used to write a data signal into a storage node and charge the storage capacitor when the switching transistor is gated. After the gating is completed, the storage node voltage is maintained by the storage capacitor in the whole frame period, so that the driving transistor can output a continuous and stable driving current for the Micro / Mini LED light emitting unit based on the voltage, thereby realizing independent and stable driving of the pixel. The technical scheme can realize high effective duty ratio, low electrical crosstalk and high precision gray scale control.
