The LCD12864 LCD screen is a relatively conventional LCD screen, and it is also a more widely used one. In recent years, most of the old 12864 LCD screens have been replaced with COG technology. The specific COG technology 12864 dot matrix LCD screen is compared to the previous one. What are the advantages and disadvantages of the COB process? Today, LCD screen manufacturers will answer for you.
LCD12864 is a kind of graphic dot matrix liquid crystal display, which is mainly composed of row driver/column driver and 128x64 full dot matrix liquid crystal display. Graphic display can be completed, 8x4 (16×16 dot matrix) Chinese characters or 16×4 (8x16 dot matrix) ASCII codes can also be displayed.

The LCD with font library provides font library fonts, but it can only display the Times New Roman of GB2312. Each has its own advantages and disadvantages, which can be selected flexibly according to different application scenarios. The schematic diagram of the LCD module is as follows:
Advantages of cOG process: 1. Low power consumption
2. The volume can be made smaller. 3. The shock resistance is good.
4. Cheap price
Disadvantages of COG process: 1. High minimum quantitative requirement 2. Relatively weak anti-interference
