The invention relates to a light-leaking detection system and method. The light-leaking detection system is applied to an electronic device to conduct light-leaking detection on a screen to be detected. The light-leaking detection system comprises an obtaining module, a dividing module, an area definition module and a detection module, wherein the obtaining module is used for obtaining the brightness values of all pixels of the screen to be detected; the dividing module is used for dividing every set of adjacent pixels in the screen to be detected into a point to be detected, and calculating and obtaining the lightness values of all the points to be detected according to the brightness values of pixels contained in all the points to be detected; the area definition module is used for defining the area formed by the multiple points to be detected in the center position of the screen to be detected as a reference area according to the positions of the points to be detected, and defining the area formed by other points to be detected around the reference area as an area to be detected; the detection module is used for comparing the brightness values of all the points to be detected in each area to be detected with the brightness value of the reference area, and detecting whether the points to be detected in each area to be detected leak light or not.
Description
technical field [0001] The invention relates to a light leakage detection system and method. Background technique [0002] At present, the screens of many electronic devices such as mobile phones, handheld computers, and tablet computers have more or less edge light leakage. Screen light leakage detection is required before electronic devices leave the factory. Most of the traditional light leakage inspections are carried out manually by naked eyes. However, the manual detection method takes a lot of time, requires a lot of manpower, has low efficiency, and cannot guarantee the accuracy of the detection results. Contents of the invention [0003] Therefore, it is necessary to provide a fast and more accurate light leakage detection system for detecting whether the screen to be tested has light leakage. [0004] It is also necessary to provide a fast and more accurate light leakage detection method for detecting whether the screen to be tested has light leakage. [0005...
