Electrophoretic display and method of driving the same
Abstract:
An electrophoretic display with threshold voltage drift compensation functionality includes a gate driving circuit, a data driving circuit, a controller and a pixel array. The gate driving circuit provides plural gate signals according to a scan control signal. The data driving circuit provides plural data signals according to a data control signal. The controller is employed to provide the scan control signal and the data control signal. The pixel array is utilized for displaying images according to the gate signals and the data signals. Each of the gate signals includes a writing enable pulse for enabling write operations of the data signals during a writing period. And during a compensation period, each of the gate signals includes a compensation pulse for performing threshold voltage drift compensation operations on the data switches of the pixel array, and the data signals are set to hold a common voltage.
