LCD module displays QR code
2-dimensional bar code (2-dimensional bar code) is a black-and-white graphic that is distributed on a plane (two-dimensional direction) with a specific geometric figure according to a certain rule to record data symbol information; it is ingenious in code compilation. It makes use of the concept of "0" and "1" bit streams that constitute the internal logic basis of the computer, and uses several geometric shapes corresponding to binary to represent text and numerical information, which is automatically read by image input devices or photoelectric scanning devices to achieve Automatic information processing: It has some commonalities of barcode technology: each code system has its specific character set; each character occupies a certain width; has a certain verification function, etc. At the same time, it also has the function of automatically identifying the information of different lines, and processing the rotation change points of the graphics.
The graphic LCD module developed and produced by TSINGTEK can display 2D barcode/QR code. Welcome new and old customers to consult!
