China 4 inch Round tft touch screen MIPI 30PIN Manufacturers, Suppliers, Factory

Overheating of the LCD screen may accelerate component aging (such as shortening the screen lifespan). In severe cases, it may cause deformation of the plastic casing, damage to the circuit insulation, and even risk fire. If abnormal overheating cannot be alleviated by the above methods, it is recommended to immediately discontinue use and send the device for repair.

Display and touch screen technology is becoming more and more mature, and there are many suppliers in the market. The production process, R&D capabilities and product reliability of different suppliers vary greatly. How to choose a reliable supplier is very important for buyers, which can reduce the troubles of many buyers and improve the quality of products.

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.

Compared with parallel ports, MIPI interface modules have the advantages of fast speed, large amount of data transmission, low power consumption, and good anti-interference. They are increasingly favored by customers and are growing rapidly.

The LCD screen itself does not emit light, and a backlight needs to be added to the back of the glass for normal display. This involves how to test the surface brightness and backlight uniformity of the LCD screen. The brightness of the LCD screen surface and backlight brightness are measured through BM -7 equipment test, the test is more accurate when the display is powered normally and displays a solid color picture.
