Xiaobian will tell you the biggest difference between cheap and expensive 12864 LCD screens today:
1. For more than 10 yuan, you can buy 12864 monochrome LCD screen with font library. Most of the goods they supply are old and disassembled on the old machine. Generally, you can't see whether it is new or old. It mainly needs you to use it for a period of time, its glass will show dark yellow, and the backlight will darken quickly. The 12864 LCD screen produced by regular or brand manufacturers will never be produced with disassembly materials.
2. Each time they produce a batch, there will be a certain difference in color. Because the selected materials are made of leftover materials from different batches and other lattice. It is not cut from a whole batch of large glass. The glass and polarizer of 12864 LCD produced by regular or brand manufacturers must have good consistency to ensure the consistency of color and quality of 12864 LCD in the same batch.
3. After sales maintenance is very difficult. Everyone on earth knows that when you buy 12864 LCD screens on Taobao, the seller is warm and considerate.

5. Using gold-plated PCB, the electroplated layer is very thin and easy to oxidize. The adhesion of bond setting line is not enough. Even if aluminum wire is used for bond setting, there will be flower screen phenomenon after using it for a short time. Regular manufacturers or brand manufacturers will choose gold plated PCB, and bond setting line must also be gold wire. In this way, the 12864 LCD can operate normally for 100000 hours.
6. Jerry built, only two backlights are used, and the brightness is increased by increasing its voltage, which is very easy to cause backlight failure. The normal 12864 LCD screen is composed of four backlights, and its service life will not be less than 50000 hours.
7. In order to upgrade Taobao store, short-term loss promotion.
