including various heterogeneous display screens (strip screen, square screen, circular screen and transflective LCD screen).

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

3.99-inch long strip LCD screen with a resolution of 400*960, supporting RGB/MIPI interfaces and featuring a capacitive touchscreen, is currently widely used in the market. Its aspect ratio is well-suited for home appliances, smart home devices, and consumer electronics. The 3.99-inch long strip screen uses common driver ICs, making debugging simple. Another core advantage lies in its unique physical shape and the fine display effect brought by its high resolution.

Many customers have reported that touchscreens easily separate from the casing in extremely cold or hot environments. This is usually due to the use of ordinary double-sided tape to fix the touchscreen. Shenzhen Hongjia Technology engineers, through extensive research, have found that using VHB double-sided tape around the edges of the touchscreen cover glass solves this problem of screen separation from the casing. In the assembly of high-end touchscreens (especially for demanding industrial, automotive, outdoor, and high-end consumer electronics products), using 3M VHB double-sided tape to fix the cover glass has become a "gold standard" process. Its advantages far outweigh traditional liquid adhesives or ordinary double-sided tapes.

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.

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.
