Abstract

The invention discloses a detection method, system and terminal of screen light leakage and a computer readable storage medium. The detection method of the screen light leakage comprises the followingsteps of using a camera to shoot the four edge areas of a screen in sequence according to a preset angle and height, wherein the screen is in the state of lightening and keeping a grey interface; conducting binary processing on images of the four edge areas obtained through shooting separately; counting the quantity of pixel grids of which pixel values are 0 of the image of each edge area after binary processing; judging whether or not the quantity of the pixel grids of which the pixel values are 0 of the image of each edge area is larger than or equal to a preset quantity to obtain a judgment result of each edge area; determining that light is leaked in the edge area of which the judgment result is yes. By means of the detection method, system and terminal of the screen light leakage andthe computer readable storage medium, through the mode of automatically detecting whether or not the light is leaked on the screen, the obtained detection result is objective and accurate, the problem that the detection result is not accurate enough due to manual factors is solved, and meanwhile, the detection efficiency is effectively improved.

Description

technical field [0001] The present invention relates to the technical field of screen detection, and more specifically, to a detection method, system, terminal and computer-readable storage medium for screen light leakage. Background technique [0002] With the development of technology, human-computer interaction has gradually become more humanized and diversified. For the user's visual interaction, the screen plays an irreplaceable role. The display of the screen has gradually developed from the initial liquid crystal to the current OLED screen, and then to the future flexible screen. The development of each technology has a great visual impact on the end product. With the continuous innovation of technology, the requirements for the screen are getting higher and higher. [0003] At present, manufacturers mainly adopt artificial subjective detection methods to detect whether the screen has light leakage. Due to the subjective factors of personnel, the detection result o...
