China 1.6 inch Round lcd display 400*400 ST7797 Manufacturers, Suppliers, Factory

​The primary part of an LCD display is an LCD panel, or liquid crystal display. It is a flat panel with two glass panels layered on top of small liquid crystal cells. The crystals align and alter the amount of light that passes through them when an electric current is applied, creating an image that can be seen.

This 3.97-inch Incell LCD supports MCU/RGB interfaces, including 8/16-bit MCU interfaces. It features IPS display with vibrant, lifelike colors across all viewing angles. This product utilizes an Incell process and features a multi-point capacitive touchscreen. A single driver IC reduces debugging time, resulting in a thin module and a reduced overall thickness.

Many customers often encounter bad or dark spots on the display screen. How do bad spots occur?

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.
