LCD display module and LCM refer to the same product. LCM (liquid crystal module) is the abbreviation of English translation of LCD module. The LCD module is a complete display module, which can be designed by assembling LCD devices, connectors, integrated circuits, control drive circuits, PCB boards, backlight and structural components according to user requirements.

 

According to different display types, LCM (liquid crystal display module type) can be divided into three main types: character dot matrix liquid crystal display module, graphic dot matrix liquid crystal display module and pen segment liquid crystal display module.

(1) Among them, the character lattice LCD module mainly includes 8 * 2 (0802 LCD module), 16 * 1 (1601 LCD module), 16 * 2 (1602 LCD module), 16 * 4 (1604 LCD module), 20 * 2 (2002 LCD module) and 20 * 4 (2004 LCD module) and other different types of character lattice LCD modules.

 

 

 

(2) The graphic dot matrix LCD module mainly includes 122 * 32 (12232 LCD module), 128 * 32 (12832 LCD module), 128 * 64 (12864 LCD module), 160 * 128 (160128 LCD module), 192 * 64 (19264 LCD module), 240 * 128 (240128 LCD module), etc.

 

 

 

(3) Generally speaking, the pen segment LCD module does not have a fixed general size module like the character type and graphic type. Most pen segment LCD modules are customized and produced according to customer needs.

 

 

 

Therefore, there is no general specification for pen segment LCD module. It is basically customized and produced according to the size limit and display size requirements of customers. LCM LCD module is a display screen composed of segment code LCD screen+backlight module; Components are components that combine LCD devices, connectors, integrated circuits, control drive circuits, PCB boards, backlights and structural components, and finally present the effect that enables users to achieve complete display.

 

 

 

There are three main types of LCD modules: one is pen-segment LCD module, the second is graphic dot matrix LCD module, and the third is character dot matrix LCD module. Pen segment LCD module is a functional component composed of segment LCD equipment and ASIC, which can only display numbers and some identification symbols. The graphic lattice LCD module is also a lattice module, which is characterized by continuous array of lattice pixels. The character dot-matrix LCD module is composed of a special driver, controller and connector for the dot-matrix character LCD device, which mainly displays digits and Western characters.
