Method of driving an organic light emitting diode (OLED) pixel, a system for driving an OLED pixel and a computer-readable medium
Abstract:
A new drive scheme is provided for OLED displays that uses a pulsed drive mode. The pulsed drive mode results in a reduced duty cycle for pixel operation. The peak OLED current is increased correspondingly to maintain a constant average luminance over the frame period so that there is no brightness loss. The method, system and computer-readable medium according to the present innovation uses a blanking signal to set the OLED pixel to black by discharging a capacitive element prior to re-programming the OLED pixel during a next synchronization cycle. An organic light emitting diode (OLED) pixel system is provided. A computer-readable medium having stored thereon computer-executable instructions is provided.
