METHOD OF PERFORMING CONVERGENCE CALIBRATION FOR A DISPLAY

摘要

A convergence calibration method for a display includes generating a test pattern of similar width with respect to a sensor and expanding the area of the test pattern from one side of the sensor until the whole sensor is illuminated. During the process of expanding the test pattern, the sensor continues to measure signals from the test patterns. Based on the maximum energy measured by the sensor, a digital judgment is performed for calculating convergence parameters.
