China 2.8 inch tft lcd 240*320 50PIN ST7789 Manufacturers, Suppliers, Factory

2.55-inch landscape LCD screen, model: HJ2550-01, 2.55-inch TFT true-color display, 320*240 resolution, supports SPI/MCU interface, also supports RGB interface, 45-pin connector, uses ILI9342C driver IC,

LCD screen itself has problems. If it is indeed the screen itself that is at fault after testing with relevant instruments, in addition to replacing a new LCD screen, the device-related software should be debugged and optimized so that the screen can work with the motherboard's CPU. The best way is to increase the OSC frequency of the IC and see how the LCD screen flickers. Of course, if the TFT LCD screen has separate row and column drivers, you can also adjust it by setting the driver chip.

Completely eliminating LCD light leakage is difficult (especially against a pure black background, where slight light leakage may occur at the edges). However, through optimized design (such as high-precision shading structures and zoned light control), the use of high-quality materials (such as low-defect light guide plates and high-light-shielding adhesive strips), and rigorous production processes (such as full lamination and precision assembly), light leakage can be significantly reduced. Shenzhen Hongjia Technology has 12 years of industry experience, specializing in the research and development, production and sales of 1.14-inch to 12.1-inch LCD screens and matching touch screens. It has rich experience in dealing with backlight leakage and can meet the demanding requirements of our customers. We can also accept customization. Customers are welcome to email us for consultation.

How MCU Drives LCD Screen and Design Considerations

Shenzhen Hongjia Technology is mass-producing 2.35-inch LCD displays with a resolution of 272*480, IPS full viewing angle, and high-definition clarity. It uses mature drivers such as ST7365 or ILI9488, supports SPI/MCU/RGB and MIPI interfaces, and is compatible with microcontrollers, saving overall system costs. Previous TFT screens smaller than 2.4 inches were mostly low-resolution 240*320, with large pixel pitch and insufficient image detail. To meet the increasing demand from customers for finer display quality
