Industrial LCD screens are widely used in automation equipment, medical instruments, transportation terminals, security monitoring, advertising displays, and other scenarios. To ensure the long-term stable operation of the screen in various complex environments, the following parameters must be considered during procurement and selection.

Basic Display Parameters

1. Screen Size

Common range: 5 inches ~ 43 inches, choose according to application space and information volume.

2. Resolution

Low-end industrial control: 800×480, 1024×768

Mid-to-high-end: 1280×800, 1920×1080 (FHD), 3840×2160 (4K)

Higher resolution results in clearer image quality, but also places higher demands on the driver board.

3. Display Mode

TN (Narrow viewing angle, low cost, fast response)

IPS/VA (Full viewing angle 178°, good color consistency)

4. Brightness (cd/m²)

Indoor Applications: 250~500 cd/m²

Outdoor High Brightness: 1000~2000 cd/m²

Medical/Commercial Displays: ≥700 cd/m²

5. Contrast Ratio

Recommended ≥800:1, Common 1000:1

High contrast ratio results in clearer image detail.

6. Color Performance

6bit + FRC: Displays 16.2M colors

8bit: Displays 16.7M colors

Some high-end medical/advertising screens support wide color gamut (NTSC ≥ 72%).

II. Interfaces and Electrical Parameters

1. Interface Types

LVDS: Commonly used in 10.1-inch to 21.5-inch industrial displays

eDP: A new generation interface with higher bandwidth, gradually replacing LVDS

HDMI / VGA / DVI: Commonly used in advertising displays and commercial displays

MIPI: Used in automotive and mobile devices

2. Power Supply Voltage

Logic Power Supply: Commonly 3.3V / 5V / 12V

Backlight Power Supply: Commonly 5V / 12V, some screens require high-voltage drivers

3. Power Consumption

Industrial LCD screens need to consider long-term energy efficiency, commonly 3W ~ 15W

III. Environmental Adaptability Parameters

1. Operating Temperature

Standard Panel: 0℃ ~ +50℃

Industrial Wide Temperature Panel: -30℃ ~ +80℃

Low Temperature Panel: Supports -40℃ start-up

2. Storage Temperature

Typically -20℃ ~ +60℃ or wider

3. Shock Resistance

≥1.5G (14.7 m/s²), suitable for industrial equipment and vehicles

4. Protection Rating

Some industrial panels have IP65/IP67 waterproof and dustproof capabilities.

IV. Lifespan and Reliability

1. Backlight Lifespan

Common LED backlight lifespan ≥ 50,000 hours

High-end industrial or advertising display screens can reach ≥ 70,000 hours

2. Surface Treatment

Matte finish, anti-glare, anti-fingerprint coating

Hard coating (3H/4H), scratch resistant

3. Certification Standards

Industrial applications require attention to CE, RoHS, FCC, and other certifications.

V. Additional Functional Parameters

Touch Configuration: Capacitive touch (multi-touch), resistive touch (supports operation with gloves)

Dim Mode: PWM dimming, automatic brightness adjustment (light sensor)

Interface Expansion: Some models support USB/I²C control

Conclusion

Selecting industrial LCD screens should not solely rely on resolution and size; key parameters such as brightness, viewing angle, operating temperature, interface compatibility, and lifespan must also be considered. The selection should be based on the specific application scenario, prioritizing models with wide temperature range, high brightness, robust protection, and long-term supply guarantees. Complete specifications should be obtained from authorized distributors to ensure stable system operation.
