Problems solved by technology
As shown in the figure, the traditional detection method of the display panel 20' needs to first cut the whole display substrate 10' into multiple display panels 20', and attach polarizers to the display panel 20' before testing. When the display panel 20' is found to be defective during the inspection process, the defective display panel 20' must be scrapped. Therefore, it is impossible to detect abnormalities and defects in the process before attaching the polarizer, which will cause waste of the polarizer.
And the detection method of the known technology, because the inspection method of a single display panel (panel) is used, more inspection equipment and inspection personnel are required, resulting in an increase in cost
[0006] Therefore, in view of the above problems, a new display panel detection method is proposed, which can not only avoid the waste of polarizers, but also detect multiple display panels at the same time to speed up the process.

Embodiment Construction
[0039] In order to make the structural features of the present invention and the achieved effects easier to understand and understand, with preferred embodiments and detailed descriptions, the descriptions are as follows:
[0040] Please also refer to figure 2 , image 3 and Figure 4 , which are respectively a flowchart of a preferred embodiment of the present invention, a perspective view of a cut display substrate, and a top view of a cut display substrate. As shown in the figure, in the testing method of the display panel of the present invention, first, step S10 is performed to set a plurality of test points 18 on the lower substrate 14 of a display substrate 10, the display substrate 10 includes a plurality of display panels 20, and the plurality of test points 18 is electrically connected with the plurality of display panels 20 (such as Figure 5A to Figure 5C shown). Then execute step S12, input a test signal at the plurality of test points 18, to transmit the tes...

The present invention relates to a detection method of a display panel. The detection method first sets a plurality of test points on a display substrate, the display substrate includes a plurality of display panels, the plurality of test points are electrically connected to the plurality of display panels, and then A test signal is input to the multiple test points, and then the image quality of the multiple display panels is detected. Therefore, the display panel is inspected before attaching the polarizer to avoid waste of the polarizer.
Description
technical field [0001] The present invention relates to a detection method, more specifically, to a detection method of a display panel. Background technique [0002] Nowadays, with the rapid development of science and technology, the types of information products are introduced to meet the needs of many users. Most of the early monitors were cathode ray tube (CRT) monitors. Due to their large size and high power consumption, and the radiation generated, there are doubts about the health of users who use the monitors for a long time. Therefore, the displays on the market today will gradually be replaced by liquid crystal displays (Liquid Crystal Displays, LCDs) for the old CRT displays. Liquid crystal displays have the advantages of being thin, light and small, low radiation and low power consumption, and thus become the mainstream in the current market. [0003] Generally, when the monitor leaves the factory, it must be tested to control the quality of the monitor and avo...
