China 1.77 inch lcd touch screen SPI Manufacturers, Suppliers, Factory

Everyone knows that the working temperature of conventional TFT LCD screen is -20 to 70 degrees, the storage temperature is -30 to 80 degrees, and the working temperature of wide temperature TFT LCD screen is -30 to 85 degrees. In order to pursue a wider working temperature, some customers will test whether TFT LCD screen can work normally under extreme temperature. Many customers find that the words displayed on the LCD screen become very light when the temperature is very low, and the words become very dark when the temperature is very high. What's going on?

Customers often report that some LCD screens produced by different screen manufacturers look cooler in color, while others look warmer in color.

3.5-inch LCD screen, vertical screen, resolution 212*318, full-view IPS, operating temperature -20 to 70 degrees, support SPI interface 3/4 lines, MCU interface 8/16 bits, RGB interface 8/16 bits, driver IC is ST7789, standard plug 45PIN, plug gold finger 0.5 spacing.

The causes of flickering streaks on LCD screens involve multiple factors, potentially related to hardware component anomalies, signal transmission issues, or external interference

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.
