의료 재활 장치는 종종 가혹한 조건에서 작동합니다., 급격한 온도 변화를 포함해, heavy electromagnetic interference and frequent touch operations. Conventional display modules tend to suffer from reduced contrast, touch failure and accelerated screen aging in high-humidity or low-temperature environments. These defects may lead to inaccurate readings and potential operational safety risks for medical equipment.
To address this industry pain point, Shenzhen NISINOPTO officially releases the 7-inch serial screen solution, designed for industrial and medical inspection devices. Integrating wide-temperature operation and AG anti-glare display performance, the solution helps equipment manufacturers reduce display failure risks and improve long-term stability of end devices.
주요 제품 특징
넓은 온도 범위: -40℃ ~ 85℃ It can withstand dramatic temperature fluctuations in rehabilitation testing environments as well as extreme conditions during storage and transportation, preventing black screen at low temperatures and color drift under high temperatures.
AG Anti-Glare Coating Adopts AG etching treatment on the glass surface to mitigate specular reflection. Operators can clearly read screen data even in wards and clinics with variable lighting conditions. Optional AR anti-reflection and AF anti-fingerprint coatings are available for high-frequency touch scenarios for easier cleaning and maintenance.
Redundant Serial Communication: RS232 / RS485 / UART Compatible with various mainboard designs for medical devices. It reduces system integration difficulty and development costs while maintaining stable data transmission in strong electromagnetic environments.
1G External Flash as Discrete Storage Unit Comes with 1G external Flash working as a discrete storage unit independent of the main MCU. Multi-language UI, high-resolution image libraries and operation guide videos can be stored locally without occupying main controller storage space. Users can update image libraries and firmware via USB or SD card on-site to cut post-sale maintenance costs.
Capacitive Touch Support Touch response speed and sensitivity can be tuned according to device operation logic, suited for frequent parameter adjustments on rehabilitation equipment.
3-Tier Customization Service Basic customization: Modify outline, dimension and pin definition Advanced customization: Custom housing, brightness enhancement and wide-temperature performance optimization High-level customization: UI 디자인, HMI interaction logic and integrated electronic control development, supporting exclusive structure & interface solutions for medical projects
기술 아키텍처 & Working Principles
AG Anti-Glare Coating Principle AG (Anti-Glare) forms micro uneven structures on glass by chemical etching to scatter incident light and reduce specular reflection. This solves the problem of poor visibility caused by ambient light reflection. AR anti-reflection and AF anti-fingerprint composite coatings can be added on demand.
Wide-Temperature Liquid Crystal Material System Specially selected wide-temperature LC materials together with optimized driving compensation circuits ensure stable liquid crystal response speed and display contrast across the full -40℃ to 85℃ range. It avoids slow LC response at low temperatures and image drift under high temperatures.
Multi-Communication Protocol Layer RS485 is ideal for long-distance transmission in industrial & medical sites with heavy EMI. RS232 serves for medium-short range board-level communication. UART handles short-range command interaction between MCU and display panel. Engineers can select interfaces flexibly based on mainboard design.
저장 & Firmware Architecture 1G external Flash acts as a discrete storage unit and collaborates with the main controller. Interface assets and firmware are stored separately. Updating screen firmware will not interfere with the host program, lowering on-site maintenance difficulty for end devices.
3-Tier Customization Logic Basic customization solves structural and interface adaptation. Advanced customization strengthens optical performance and environmental resistance. High-level customization delivers integrated development of UI, HMI and electronic control for deep customization of medical equipment projects.
