The material design of underwater touch screens must focus on the three core goals of "waterproof and water-proof, corrosion-resistant and non-failure, and touch without misjudgment". The super-hydrophobic cover layer is used to reduce water interference, corrosion-resistant conductive materials replace traditional ITO, and precision sealing structures block water penetration. In addition, the appropriate material combination is selected in combination with scene requirements (such as consumer grade/industrial grade/deep sea grade).

The LCD TE pin, defined as the "Tearing Effect," primarily serves a data synchronization function, converting analog signals captured by the camera into digital image signals. The host then transmits these digital image signals to the display, which can cause image tearing. To address this issue, the TE function was introduced, allowing a complete, tear-free image frame to be transmitted to the display. Screen clipping can often occur when using a portrait screen as a landscape screen if improperly configured. If the LCD screen has a TE interface, it is recommended to connect the TE pin.

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

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.

with a resolution of 1200*1920, a MIPI interface vertical screen, a brightness of 1500 lumens, which is clearly visible under strong outdoor light, and a contrast ratio of 1200.

Shenzhen Hongjia Technology has launched a 3.0-inch IPS display for the handheld small game console market. It has a resolution of 320*480 high-definition and delicate, 4:3 structure, horizontal display, and ultra-narrow frame; it uses high-brightness and low-power LED lights, which are clearly readable in outdoor sunlight, and the brightness can reach 1000 lumens; it supports 16/18/24BIT RGB interface and 39PIN standard interface.
