Outdoor-grade 5-inch G+G capacitive touch panel with a 16:9 vertical viewport. Features 5-hole precision CNC carving and UV-resistant white silk-screening for smart access control terminals.
Case Details:
Recently, a client entrusted our company with the custom development of a touch panel for their human-machine interface (HMI) access control terminal. To address the light-transmittance alignment needs for multiple cameras and sensors on the 5-inch narrow-long screen, our technical team tailored this 16:9 vertical viewport white capacitive touchscreen panel based on industrial-grade customization standards. This solution solves the assembly pain points of non-standard smart access control devices under irregular shape processing and complex weather-resistant environments.
Project Background:
According to client feedback, modern smart building face recognition terminals not only require sensitive touch interaction but also need to integrate multiple sets of precision components—such as dual cameras, infrared fill lights, and proximity sensors—on the front panel. Standard public-mold touchscreen panels cannot provide high-precision and high-quantity hole positions. Meanwhile, white access control panels face long-term exposure to direct ultraviolet (UV) rays. Conventional industrial inks are highly prone to yellowing, fading, and interlayer cracking under baking sunlight and alternating outdoor temperature variations. To safeguard the impact resistance of the 5-inch narrow-long screen while achieving precise light capture for multiple lenses and long-lasting, premium visual aesthetics, the client chose to cooperate with our company to customize the cover lens process.
Key Solutions:
- 5-Hole High-Precision CNC Carving and Edge R-Angle Passivation Process:
Aligned with the vertical viewport layout of the product, our engineering team utilized a high-precision digital control CNC glass carving machine to complete 5-hole high-precision CNC carving in the non-display area of the cover lens. This accommodates the non-standard hole requirements for the dual cameras, fill lights, and sensors. To eliminate stress concentration after irregular-shaped processing, all edges of the cover glass underwent edge R-angle passivation treatment to prevent edge chipping.
- Silk-screening with UV-resistant and high-temperature resistant white ink：
To tackle the yellowing issue of semi-outdoor white panels, this 5-inch capacitive touch panel selected UV-resistant and high-temperature-resistant white ink during the silk-screening stage. This ink possesses a UV-stable structure along with exceptional heat and weather resistance. Even if the terminal device is situated year-round in outdoor environments with high temperature variations and direct intense sunlight, the white silk-screened layer maintains its initial properties without yellowing or leaking light, ensuring the long-term premium texture of the all-in-one access control machine.
- 5-inch16:9 Vertical Viewport and G+G Dual-Glass Structure:
The panel structure adopts a classic G+G dual-glass structure, featuring a True Flat integrated surface design. The 16:9 vertical viewport matches the longitudinal visual interaction of face recognition terminals. The surface cover lens and internal sensor layer utilize the OCA full-bonding process, which works in tandem with the filtering algorithms of the touch IC to ensure the screen maintains sensitive multi-point touch feedback.
