Problems solved by technology
[0008] However, there are more or less problems in the above methods: in the first method, if the amount of liquid crystal bubbles in the process is insufficient to cause vacuum LC bubbles, it cannot be observed from the appearance; in the second method, it cannot be done due to heat. To be absolutely uniform, in addition, there may be gas out of the material, making it impossible to accurately determine the source of the gas, that is, if the liquid crystal bubbles are not entered by external air, but because the material gas inside the cell has escaped, it will interfere with the analysis results; the third method In the experiment, because the red ink molecules are relatively large, and the gaps in the frame glue in the experiment are small, it often appears that the red ink cannot penetrate during the experiment.
Therefore, the existing technology has no way to accurately and effectively clarify and analyze the type of gas contained in the LC Bubble, and it is also not conducive to finding the source of the gas and improving the quality of the panel

Embodiment Construction
[0030] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0031] refer to figure 1 , the liquid crystal panel 100 of the present invention includes a CF substrate 101 and an array substrate 102 arranged in parallel and facing each other, a liquid crystal 103 and a sealant 104, the liquid crystal 103 is filled between the CF substrate 101 and the array substrate 102, and the sealant 104 surrounds the liquid crystal 103 , sealing the liquid crystal 103 therein. Generally, LC Bubble B is likely to appear on the surface where the liquid crystal 103 is in contact with the CF substrate 101 and the array substrate 102 .
[0032] Such as figure 2 As shown,...

The invention discloses a device for analyzing liquid crystal bubble. The device comprises a vacuum treatment chamber, a weighing mechanism and a disassembling mechanism. The weighing mechanism and the disassembling mechanism are arranged in the treatment chamber, and the disassembling mechanism is used for separating substrates of liquid crystal panels on the weighing mechanisms from liquid crystals; the weighing mechanism is used for weighing the liquid crystal panels with the liquid crystals in separation states. The invention further discloses a method for analyzing the liquid crystal bubble. The device and the method for analyzing the liquid crystal bubble have the advantages that the types of gas in the liquid crystal bubble can be accurately and effectively judged by the aid of the device, and accordingly the device and the method can bring convenience for searching gas sources and improving the quality of the panels.
Description
technical field [0001] The invention relates to the technical field of liquid crystal panel detection, in particular to a liquid crystal bubble analysis device and analysis method. Background technique [0002] The LCD panel is mainly composed of CF (color filter, color filter) glass substrate and Array (array) glass substrate, and liquid crystal is dripped between the two substrates, and then sealed with frame glue around the liquid crystal. [0003] In various actions or states during the production process and reliability test, such as high temperature and high humidity operation, high temperature and high humidity storage state, low temperature operation, low temperature storage state, etc., LC Bubbles (liquid crystal bubbles) often appear on the LCD panel. [0004] The existing methods for analyzing LC Bubble mainly include: [0005] 1. Check the appearance with a microscope to confirm whether the LCD panel is damaged, and the line corresponding to the LC Bubble will h...
