Method and system for illuminating a layer of electro-optical material with pulses of light

摘要

A monitor pixel that includes a portion of the layer of electro-optical material is provided. A measured response time of the electro-optical material is measured using the monitor pixel. Illumination of the layer of the electro-optical material is then delayed by a time corresponding to the measured response time of the electro-optical material. The system for illuminating a layer of electro-optical material with pulses of light comprises a monitor pixel, a monitor pixel driver, an optical response detector and an illumination control circuit. The monitor pixel includes a portion of the layer of electro-optical material. The monitor pixel driver is configured to drive the monitor pixel with a monitor pixel drive signal. The optical response detector is coupled to the monitor pixel and is configured to generate a detection signal indicating a change in an optical property of the monitor pixel. The response time measurement circuit is configured to measure a measured response time of the electro-optical material in response to the monitor pixel drive signal and the detection signal. The illumination control circuit is configured to delay illumination of the layer of the electro-optical material by a time corresponding to the measured response time of the electro-optical material.
