Our products are divided into two categories：“ Monochrome screen”and“ TFT intelligent color screen;.Monochrome screens include COG display screens and COB modules, while intelligent color screens include various standard sizes with resolutions up to 1365 * RGB * 768. Below are specific introductions to the characteristics and advantages of these two types of products!

Monochrome screenCOG display screens have the advantages of being light, thin, low power consumption (LCD operating current less than 1mA), multiple interfaces (SPI serial port, 8-bit parallel port, some products can also be IIC), and easy to use. Currently, our company has over a hundred COG products to choose from; COG display screens can also be combined with PCB boards to form products with a structure similar to COB. They can communicate via SPI serial or parallel ports and can be powered by 3.3V or 5V. COB modules have advantages such as standardized specifications, market universality, and performance stability, and corresponding sizes are basically available in Chinese font versions.

The character dot matrix includes:08x2 rows, 16x2 rows, 20x2 rows, 24x2 rows, 40x2 rows, 16x4 rows, 20x4 rows, 40x4 rowsWait, wait.

The graphic dot matrix (some products include character libraries) includes:122x32 lattice, 128x32 lattice, 144x32 lattice, 162x32 lattice, 192x32 lattice, 128x64 lattice, 192x64 lattice, 240x64 lattice, 128x128 lattice, 240x128 lattice, 160x160 lattice, 240x160 lattice, 320x240 lattice, as well as other specifications of dot matrix.

TFT intelligent color screenResolution inWithin 1365RGB * 768Both can achieve intelligent products, and the communication interface includes TTL232\/RS232、 RS485、USB、CAN、 High speed interfaces such as Ethernet, as well as various video interfaces.
