Embodiment Construction

[0028] Such as figure 1 As shown, the present invention provides a method for detecting the screen quality of a display device. The display device includes a signal source interface, including the following steps:

[0029] S1. Obtain the image displayed on the screen collected by the image acquisition device, the image displayed on the screen is generated based on the image detection signal input to the signal source interface, and the image detection signal is a monochromatic field image signal;

[0030] S2. Analyze the image collected by the image collection device to obtain a screen quality detection result. The images collected by the image acquisition device are obtained through USB, LAN, Bluetooth or WiFi.

[0031] Wherein step S2 comprises again:

[0032] S21. Divide the screen display area into multiple detection areas according to the brightness and / or brightness change rate of the original image, where the original image is an image collected by the image acquisiti...

Abstract

The invention discloses a screen quality detection method, a device and a system for display equipment. The display equipment comprises a signal source interface, the screen quality detection method of the display equipment comprises the following steps: acquiring an image which is acquired by an image acquisition device and displayed on a screen, the image displayed on the screen is generated based on an image detection signal input into the signal source interface, and the image detection signal is a monochromatic field image signal; and analyzing the image acquired by the image acquisitiondevice to obtain a screen quality detection result. Compared with the prior art, the method has the advantages that full-automatic detection of the screen quality on the television production line isachieved, the labor cost and the false detection and missing detection probability are greatly reduced, the production takt is fixed, and the production efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of display device detection, in particular to a method, device and system for detecting screen quality of a display device. Background technique [0002] At present, China's TV manufacturing industry still uses workers to inspect each function of the TV one by one on the assembly line when inspecting the assembled TVs before leaving the factory. For the defects of the LCD screen, it is still mainly based on manual subjective inspection. Judging does not really achieve a rigorous and objective standard. At the same time, production line inspection workers need to have rich experience in order to achieve a low number of missed inspections, and it takes a lot of time to train a qualified inspection worker. The detection of sound defects by workers is still a relatively rudimentary way of listening with human ears, which prompted the appearance of this machine. This machine will replace traditional manua...
