[0006] The current method of testing the curing rate of the sealant is to use an external force to pull the CF substrate and the TFT substrate apart, but because the adhesion between the sealant and the black matrix (BM) is greater than the adhesion between the black matrix and the glass, the CF substrate and the TFT substrate are separated. Sometimes it appears that the black matrix on the surface of the CF substrate is peeled off from the CF substrate and covers the frame rubber surface of the TFT substrate, which affects the sampling test of the frame rubber. At present, the black matrix on the surface of the frame rubber can only be scraped off with a blade, and then Then test the curing rate of the frame glue
However, this method of removing the black matrix is difficult to operate, and the success rate is low, which affects the feasibility of the test

The invention provides a preparation method of a frame adhesive curing rate test sample and a frame adhesive curing rate testing method. According to the preparation method of the frame adhesive curing rate test sample, black matrixes on the surface of a frame adhesive are removed through an alkaline solution, operation is easy, the success rate is high, and the surface of the prepared frame adhesive curing rate test sample is clean and free of black matrix residues. According to the frame adhesive curing rate testing method, after the black matrixes on the surface of the frame adhesive are removed through the alkaline solution, an infrared spectrogram of the frame adhesive is tested through an infrared spectrometer, and then the frame adhesive curing rate is obtained through calculation. The methods are easy to operate, the performability of frame adhesive curing rate testing is improved, the accuracy of a testing result is high, and data is supplied to manufacture procedure monitoring and frame adhesive abnormity analyzing.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a method for preparing a sample for testing the curing rate of a sealant and a method for testing the curing rate of a sealant. Background technique [0002] With the development of display technology, liquid crystal displays (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, televisions, personal Various consumer electronic products such as digital assistants, digital cameras, notebook computers, and desktop computers have become the mainstream of display devices. [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal displays, which include a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to place liquid crystal molecules between two parallel glass substrates. There are many vertical and horizontal small wires between...
