How to choose an industrial LCD screen with appropriate resolution?
Date:2025-09-28
The key to selecting a suitable resolution industrial LCD screen for industrial equipment is to find the optimal balance between display accuracy, cost, performance, and reliability. The higher the resolution, the better, but it should perfectly match your actual application scenario.
The table below summarizes the resolution selection strategies for different application scenarios, so you can quickly locate your situation first.
Mainly considering dimensions | Recommended resolution range |
The complexity of displaying content | Simple UI, numbers, icons: 800 × 480 |
Complex charts and data dashboards: 1280 × 800 |
High definition image, fine details: 1920 × 1080 (FHD) or higher |
Viewing distance and screen size | Small size (below 10.1 inches), up close viewing: recommended ≥ 1280 × 800 |
Medium size (12-15 inches), mid-range viewing: 1920 × 1080 (FHD) is a common choice |
High definition image, fine details: 1920 × 1080 (FHD) or higher |
Environmental light and visibility | Strong light environment (outdoor/semi outdoor): While ensuring high brightness (≥ 700nit), moderate resolution (such as 1280 × 800) may be more practical than top-level resolution |
Pay attention to these key factors related to resolution
The choice of resolution is not isolated, it can also affect other aspects and requires comprehensive consideration:
Interface type matching: High resolution requires interfaces with higher bandwidth to stably transmit signals. For example, for resolutions of 1920x1080 or higher, eDP or LVDS interfaces are recommended as they have stronger anti-interference capabilities in industrial environments. Traditional VGA interfaces are susceptible to interference at higher resolutions and are not suitable for complex industrial environments.
Balance between cost and stability: The higher the resolution, the higher the cost. Meanwhile, ensuring the long-term stable operation of high-resolution screens under harsh conditions such as extreme temperature and vibration is more challenging than in consumer grade products. Therefore, do not blindly pursue ultra-high resolution. The primary focus of industrial applications is stability and reliability.
Understanding Pixel Density (PPI): PPI (number of pixels per inch) is a direct indicator of screen clarity. It is determined by both screen size and resolution. For example, on a 10.1-inch screen, a resolution of 1280x800 is approximately equal to 149 PPI, while a resolution of 1920x1200 can reach approximately 224 PPI, which is noticeably finer. You can infer the required resolution based on the desired clarity requirement.
Avoid these common selection misconceptions
Misconception 1: Only focus on resolution and ignore interface compatibility. Be sure to confirm that your motherboard or controller supports the interface type of the selected screen (such as LVDS, eDP, MIPI, etc.).
Misconception 2: Blindly pursuing high resolution and ignoring long-term usage costs. High resolution screens typically have higher power consumption, and when deployed on a large scale, electricity and maintenance costs are factors to consider.
Misconception 3: Ignoring the challenge of ambient light. In strong light environments, screen brightness (nits value) and anti glare treatment are more important than simply high resolution. Be sure to choose a high brightness screen (≥ 700nit) for outdoor or strong light environments.
Brief summary
Remember a core principle: choose on demand. First, clarify what content your device needs to display, what distance and environment users are viewing from, and then combine with your budget to greatly narrow down the selection range.
I hope this information can help you make decisions. If you could share more information about the specific industries and types of displays your device is used in, perhaps I can provide more specific suggestions.
