Abstract

The invention discloses a full-automatic test machine and a test method for a display panel. The test machine comprises a machine body, a test clamp for positioning the display panel, an image detecting part for obtaining contents displayed on a display screen of each display panel by photographing, a central control processing unit for inputting display instructions to the display panel and comparing the contents obtained by the image detecting part with the reference contents, and a display device for displaying the comparison results. The test clamp is mounted on the machine body; the imagedetecting part is connected to the central control processing unit; and the display device is connected to the central control processing unit. The full-automatic test machine for the display panel further comprises a signal sampling circuit, and the image detecting part is electrically connected to the central control processing unit through the signal sampling circuit. According to the full-automatic test machine and the test method for the display panel, the test machine can test the display panel automatically; the full-automatic test machine for the display panel can detect the display panel sensitively and reliably, through the signal sampling circuit; and the accuracy of the display is high.

Description

technical field [0001] The invention relates to a display board automatic testing machine and a display board testing method, which are especially suitable for testing multiple display boards at the same time. Background technique [0002] At present, with the development of science and technology, various household equipment and office equipment are provided with display boards (also called display bars, display screens, etc.) for displaying various parameters of equipment status. For example, the air conditioner is provided with a display panel, on which various parameters such as air conditioner switch, refrigeration, heating, dehumidification, and defrosting icons are displayed. In addition, display boards are also installed on washing machines, water heaters, vehicle meters and other equipment. Traditionally, when it is necessary to test the display board, it is generally done manually, and the detection speed is slow, and it is difficult to realize automated batch tes...
