Abstract
A light emitting display device includes a substrate, a drive power circuit, a gate circuit unit, multiple LEDs and a power switch unit. The power switch unit includes multiple first transistor switches and at least one second transistor switch that cooperatively control current flows through the LEDs. The first transistor switches are respectively connected to first terminals of the LEDs. The at least one second transistor switch is connected to second terminals of the LEDs. The first transistor switches are further connected to the drive power circuit to receive multiple drive currents, and are further connected to the gate circuit unit to receive a timing input. The at least one second transistor switch is further connected to the gate circuit unit to receive a timing input. The light emitting display device can have reduced parasitic capacitance effect, and thus reduced power consumption and have improved display quality.
