摘要
The present invention discloses a method for fast judging and optimizing light emitting quality of a light guide plate based on an image processing technology. According to the method, an illuminance diagram of the light guide plate is regarded as a single-color image, illuminance information is converted into a gray level, gray levels of all pixel points are calculated through a gray level histogram, the light outgoing quality of the light guide plate is analyzed according to a discrete degree of the gray levels, positions of the gray levels discrete in distribution in the gray level histogram on the illuminance diagram are found out through programming, a net point filling rate in a corresponding area is directly optimized and is eliminated, and a uniformity degree evaluation formula with a precision P judgment criterion is given. The present invention effectively improves the optimizing efficiency of the light guide plate, and an optimized result is closer to an actual visual effect.
