Abstract:
1. A display apparatus comprising: a micro-shutter including a first electrode and a second electrode; a latch circuit including a first input node, a second input node, a first output node connected to the first electrode, and a second output node connected to the second electrode to receive an operation voltage and a common voltage; a capacitor including a first electrode and a second electrode applied with a shutter voltage; a first switching device applying a data signal to the first electrode of the capacitor in response to a gate signal; and a second switching device applying a voltage of the first electrode of the capacitor to the first input node of the latch circuit in response to an update voltage, wherein the latch circuit is initialized when the operation voltage is set to a ground voltage, the common voltage is set to a first voltage level higher than the ground voltage, and the common voltage is set to a second voltage level higher than the first voltage level after the latch circuit is initialized before the operation voltage is boosted to an activation level.
