In the fastest year of LCD LCD screen development, many emerging LCD factories have appeared in the mainland. Among them, Jiangxi and Hunan are more densely built. According to expert analysis, LCD LCD screen manufacturers have reached the market’s guarantee and are completely in a supply chain. Under the state of exceeding demand, many LCD makers are forced to compete at low prices, a vicious circle, and many LCD makers are gradually transforming.


Why is it that the larger the size of the LCD screen, the more difficult it is for the factory to make it? The following LCD liquid crystal display factory makes a brief introduction:


LCD screens are mainly based on LCD black and white screens and TFT color screens. The following mainly introduces the relationship between the production difficulty and size of LCD black and white screens: expert statistics, the size and process difficulty of LCD segment code screens have this Law: The larger the size, the more complicated the production process, mainly due to the following reasons:


1. The larger the size of the LCD liquid crystal display, the higher the defective rate of the product.


2. The larger the size of the LCD liquid crystal display, the harder it is for employees to operate.


3. The larger the size of the LCD liquid crystal display, the higher the level of equipment requirements.


4. The larger the size of the LCD screen, the more undesirable situations will appear, such as darkening.




Which of the defective LCD liquid crystal displays is the most difficult to control?


To know which of the defective LCD liquid crystal displays is the most difficult to control, we must first know the classification of the defective LCD liquid crystal display:


1. Poor previous process


The pre-process defects of the LCD liquid crystal display mainly include the following defects: lack of scratches, short circuits, high currents, poor screen printing, internal contamination, and misalignment of fit, etc.


2. Poor middle process


The pre-process defects of LCD liquid crystal display mainly include the following defects: poor cutting, liquid leakage, liquid crystal contamination, uneven cell thickness, and dirty cleaning.


3. Poor post-process


The pre-process defects of the LCD liquid crystal display mainly include the following defects: poor electrical measurement, poor placement, and misaligned mounting feet.


There are three stages of defects. Among them, the previous process is the most difficult to control. Among the previous process, I personally think that the internal pollution is the most difficult to control, because the internal pollution is not only related to the environment, but also related to the operation of the personnel, and also related to the performance of the equipment , Such as powder spraying, it is easy to form a dough, and the position occupied is all the positions in the previous process, all this defect is the most difficult to control.
