Abstract
Provided is a voltage-input input pixel driving circuit for a microdisplay panel. The voltage-input pixel driving circuit includes: a first transistor, a second transistor, a driving transistor, a coupling capacitor, a light-emitting element, and a MUX signal gating unit. The first transistor includes a gate connected to a scan signal line (SCAN) of the microdisplay panel, a source connected to a data signal line (DATA) of the microdisplay panel, and a drain connected to a source of the second transistor; a gate of the second transistor is connected to an external bias voltage (VBIAS), a drain of the second transistor is connected to a gate of the driving transistor, a source of the driving transistor is connected to one end of the light-emitting element, the other end of the light-emitting element is connected to a common voltage (VCOM).
