Automatic display screen image quality detection system and method and application thereof

Abstract

The invention provides an automatic display screen image quality detection system and method and an application thereof. The system comprises an image input device that is arranged on a front end of a detected display screen, an image collection card that is connected with the image input device and is used for processing information collected by the image input device, and an upper computer that is connected with the image collection card and is used for processing the collected data. The image collection technology of the image input device, the image chroma reading technology of the image collection card and the technical analysis and automatic alarm technology of the upper computer are combined; and in view of the low manual image quality detection frequency, high cost, strong subjectivity and other problems in a display screen test process, splash screen, black screen, color cast and other conditions in the display screen test process are checked by the combination of software and hardware, automatic data collection, process and analysis and timely result feedback, whether the checked display screen is in a normal working state is automatically determined, and automatic alarm is carried out in the case of the above undesirable effects. The structure is simple, the cost is low, the detection result is reliable and the detection yield is improved.

Description

technical field [0001] The invention relates to the field of display screen image quality detection, and more specifically, to a display screen image quality automatic detection system, detection method and application thereof. Background technique [0002] At present, the main operation method of laboratory display screen image quality inspection is as follows: During the experiment, the display screen is directly observed by human eyes, and the image quality of the display screen is checked under different display sample colors, so as to determine whether the display screen is in a normal working state . [0003] However, this method of monitoring the experimental process by manpower has the following problems: most tests cannot be followed up in real time, and the experiment can only be followed up through a certain frequency of inspection; the required labor cost is high, and the experiment cost is expensive ; Judgment by people, too subjective, lack of customer. Cont...

Problems solved by technology

[0006] Combining the image acquisition of the image input device, the image chromaticity reading of the image acquisition card, and the technology analysis and automatic alarm of the host computer and other technologies; in order to solve the problems of low frequency, high cost and strong subjectivity of manual detection of image quality in the process of display screen testing , through the combination of software and hardware, automatically collect, process, and analyze data, and timely feedback the results, check the flickering screen, black screen, color cast, etc. that appear during the test process of the display screen, and automatically determine whether the checked display screen is normal Working status, if the above-mentioned bad phenomenon occurs, it will automatically alarm
