China 2.8 inch touch screen ST7789 40PIN Manufacturers, Suppliers, Factory

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.

Usually, touchable LCD screens are capacitive screens, and the positioning method of the touch screen is through the electric field. Therefore, when static electricity and discharge occur, the LCD touch screen will have a "drift" screen effect, that is, the click position is offset from the actual response position.

Shenzhen Hongjia Technology specializes in the production of 1.47-inch to 10.1-inch display screens and matching touch screens, including low-power, semi-transparent, wide temperature, and high-definition display screens with a full range of sizes and multiple interfaces. Customers are welcome to email us for consultation.

After VGA, QVGA, WVGA, and HVGA resolution products were gradually born. These resolutions can be seen everywhere in the mobile phone parameters. The following is the explanation and difference of VGA, QVGA, WVGA, and HVGA.

When encountering afterimage, we need to rule out whether it is a hardware problem or a software problem, so that we can find a solution. Shenzhen Hongjia Technology specializes in R&D, production and sales of 1.14-inch to 15-inch LCD screens and matching touch screens. It has 12 years of industry experience and a group of experienced engineers. It can provide customers with one-stop solutions and can also be customized. You are welcome to email us for consultation.

In today's consumer electronics industry, both technologies are widely used, often appearing in the same device. For example, in an ultra-thin laptop, the main connection between the motherboard and screen might use direct gold-finger connectors for the sake of thinness, while the connections between the motherboard and components like the touchpad and keyboard might use traditional connectors. If reliability and maintainability are more important than saving a fraction of a millimeter in thickness, then connectors are a more reliable and mature choice. If you are building an ultra-thin, cost-sensitive new product with a high-precision automated production line, you should carefully consider the direct gold-finger connector solution.
