Compared to a 3.5-inch screen, the 4.3-inch LCD screen not only maintains good embeddability but also provides a larger viewing area and higher resolution, making it widely used in fields requiring richer information interaction. The table below summarizes its main applications:
Application Industry | Typical equipment/scenario | Core needs and screen advantages |
Industrial automation and control | High-end Human-Machine Interface (HMI), handheld industrial terminal, robot teaching pendant, industrial touch screen unit | Resistant to harsh environments (wide temperature range, shockproof), with reliable touch functionality (supporting glove-operable resistive screens or high-precision capacitive screens). |
Professional instruments and medical equipment | High-precision measuring instruments, portable medical diagnostic equipment, and life monitors. | High reliability, wide viewing angle/high contrast ratio (IPS screen ensures multi-angle interpretation), readable in sunlight (high brightness). |
Vehicle-mounted and mobile devices | On-board terminals for construction machinery, controllers for heavy equipment, taxi meters, and portable navigation devices. | High brightness (>400 cd/m², visible in sunlight), wide temperature operation (-20~70℃), shock resistance. |
Smart home and Internet of Things | Intelligent central control screen, high-end home appliance control panel, security system interface. | Interactive-friendly (capacitive touch), exquisite appearance (full lamination, narrow frame design). |
Consumer and commercial electronics | Handheld game consoles, smart POS machines, self-service terminals, and development platforms for teaching/research purposes | High cost-effectiveness, universal interfaces (such as RGB, SPI), and abundant development resources. |
How to choose a 4.3-inch screen?
When making a choice, apart from general factors (interface, touch control method), special attention should also be paid to:
1. Resolution: There are two mainstream resolutions: 480x272 (WVGA) and 800x480 (WVGA). The latter offers finer details in displaying charts and text, albeit at a slightly higher cost.
2. Viewing angle: IPS technology offers a full viewing angle; O-Film's uniform wide viewing angle technology provides a higher cost-performance ratio in industrial applications.
3. Brightness and reliability:
Outdoors/under strong light: Choose a high brightness model (≥500 cd/m², preferably a model readable in sunlight).
Harsh industrial environment: Confirm the operating temperature range (typically -20℃~70℃) and protection level (such as IP65 for vehicle applications).
