China 3.5 inch touch screen 320*480 40PIN RGB/SPI Manufacturers, Suppliers, Factory

mainly reflected in high-speed transmission, simplified wiring, low power consumption, high compatibility and other aspects. The following is a detailed analysis of its "advantages" from the perspective of technical principles and practical applications

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.

The HJ2101-02 is a 2.1-inch round LCD with a MIPI interface, supporting a variety of resolutions, including 540*540, 480*480, and 360*360. Compared to the 480*480 2.1-inch round screens on the market, it offers higher-definition, finer-grained displays with more vivid and lifelike colors.

Generally, customers think that LCD screen flower screen is a hardware problem, but in fact, software driver problems may also cause it. Customers need to be guided to check step by step to find the problem.

3.17-inch TFT display screen with a resolution between 3.0 and 3.5 inches, featuring a wide viewing angle, a 320*480 pixel resolution, and either the ILI9488 or ST7796 driver IC. It supports SPI/MCU/RGB interfaces with standard 45-pin and 40-pin connectors, making it suitable for customers using microcontrollers.

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.
