At present, the use of intelligent mobile phone mobile phone screen because of the different levels of LCD technology mobile phone, so the mobile phone screen using LCD types are different, now mobile phone screen LCD classification can be divided into TFT, TFD, UFB, STN and OLED, most have a small clever, can drive the use of low voltage, less power consumption, long service life etc.. But there are many differences between these LCD. But for large LED dispensers, these displays can be used for dispensing. What are the characteristics of large LED dispensers? There are many characteristics of a large LED dispensing machine, with a large table, for dispensing of larger dispensing products, using power mode as the driving force, to strengthen the control of the glue dispensing machine LED, and use the visual positioning system, three axis positioning system to improve the gel point coordinate precision, reducing the dispensing error. These functions are very important for the precise dot glue on the phone screen, which allows the glue dispenser to make high precision glue when it is glued to the screen of the mobile phone. Not only that, the large LED dispenser can also make precise glue to other electronic products, such as cell phone batteries, relays, MP3 and so on. In addition, other industries can also be used to make drops.
