China 5 inch lcd display 480*854 Manufacturers, Suppliers, Factory

Small and medium size LCD screen IC supplier

This 5-inch round LCD screen features IPS full-viewing angle, a 1080*1080 resolution, a MIPI interface, a 1300 contrast ratio, 16.7M colors, and a 50-pin pin configuration. It operates in temperatures from -20°C to 60°C and has a storage temperature range of -30°C to 70°C. It features a multi-point capacitive touchscreen using the GT911 touchscreen IC with a GFF structure and an I2C interface.

In the field of small-size TFT screen driver ICs, ST7796 and ILI9488 ICs are often used by customers. Many customers also have questions when choosing ICs. Which IC is more cost-effective and has better performance? Today I will briefly express my views here. If users are making devices that require high refresh rates, such as gaming devices or video playback, ST7796U may be more suitable. ILI9488 may have more advantages in cost or be more flexible in some interfaces.

The material design of underwater touch screens must focus on the three core goals of "waterproof and water-proof, corrosion-resistant and non-failure, and touch without misjudgment". The super-hydrophobic cover layer is used to reduce water interference, corrosion-resistant conductive materials replace traditional ITO, and precision sealing structures block water penetration. In addition, the appropriate material combination is selected in combination with scene requirements (such as consumer grade/industrial grade/deep sea grade).

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?

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.
