Abstract
A display device includes a plurality of pixels, a gate control line electrically connected to the pixels, an auxiliary power line isolated from the gate control line, and a number of auxiliary switches between the gate control line and the auxiliary power line. The at least one auxiliary switch is controlled by an auxiliary control line isolated from the auxiliary power line and the gate control line. The at least one auxiliary switch electrically connects the gate control line and the auxiliary power line.
Claims20
A display device, comprising:
- a plurality of pixels;
- a gate control line electrically connected to the pixels;
- an auxiliary power line isolated from the gate control line;
- an inverter connected between the gate control line and an auxiliary control line;
- and
- a number of auxiliary switches between the gate control line and the auxiliary power line, wherein the at least one auxiliary switch is to be controlled by the auxiliary control line isolated from the auxiliary power line and the gate control line, and wherein the at least one auxiliary switch electrically connects the gate control line and the auxiliary power line, wherein signals supplied to the gate control line and the auxiliary control line are complementary signals.
A method of driving a display device, the method comprising:
- applying a gate control signal to a gate control line;
- applying an auxiliary voltage to an auxiliary power line;
- applying a complementary signal to an auxiliary control line by inverting a signal on the gate control line;
- and
- applying the auxiliary voltage to the gate control line by turning on an auxiliary switch electrically connected between the auxiliary power line and the gate control line in response to the complementary signal on an auxiliary control line, wherein the gate control line is electrically connected to at least one pixel of the display device.
An apparatus, comprising:
- an interface;
- and
- a controller including or connected to the interface,
- wherein the controller is to control generation of a first signal to a gate control line, a second signal to a power line, and a third signal to control a switch between the gate control line and the power line, the second signal adding power from the power line to the gate control line to increase a turn on rate of the switch, the gate control line electrically connected to a gate of a transistor of a pixel in a display device, wherein the first and third signals are complementary signals.
