China 2.8 inch touch screen ST7789 Manufacturers, Suppliers, Factory

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.

​An LCD display module is an electronic component used for displaying characters, symbols, and graphics in a clear, easy-to-read format. It typically consists of a liquid crystal display (LCD) panel, a driver circuit board, and other supporting components, such as backlighting and a controller chip.

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.
