The demand for 19-inch LCD become the focus of procurement

Driven by the continuous advancement of Industry 4.0 and intelligent manufacturing, the market demand for industrial control

display devices, which serve as the key interface for human-machine interaction, remains steadily increasing. Among them, 

19 inch LCD screens have gained significant popularity. 

With its moderate size, excellent compatibility and mature supply chain, it has always occupied the position of "golden size" in 

fields such as mechanical automation, medical equipment and rail transportation. 

As the original manufacturer of 19-inch industrial control LCD screens (19inch TFT LCD ), we will bring you on the  latest 

information from three aspects: market trends, technical requirements, and procurement suggestions.

I. Market Demand: Steady Growth and Continuous Expansion of Application Fields 

Although large-sized displays are the future trend, the demand for 19-inch industrial control screens in specific scenarios 

remains irreplaceable. The main driving forces come from: 

1. Equipment upgrade and replacement: The standard size of display panels for traditional industrial equipment (such as 

CNC machine tools and PLC control cabinets) is mostly 19 inches. When equipment is updated or renovated, 

Same size replacement is the most efficient and economical choice. 

2. Space limitation requirements: In devices with strict installation space constraints such as medical equipment, rail 

transit arriages, and financial ATMs, 19-inch screens offer a balance between display area and space occupied. 

The best balance has been achieved in terms of space utilization. 

3. Cost-effectiveness advantage: Compared with larger-sized screens, 19-inch screens have obvious advantages in terms 

of procurement cost and power consumption control, making them the ideal choice for customers seeking high cost 

performance choice. 

At present, apart from traditional industrial control, its application in emerging fields such as new retail self-service 

terminals, intelligent warehousing and logistics sorting systems, and security monitoring centers is also rising rapidly. 

II. Technical Focus: High brightness, wide temperature range and ultra-long lifespan are the core indicators. 

At present, the requirements of downstream customers for 19-inch industrial control screens have comprehensively 

shifted from "usable" to "easy to use and durable". Please pay close attention to the following technical parameters 

when making 

purchases: 

High brightness and wide viewing angles: In factory environments with complex lighting conditions, a brightness of 

500-1000 cd/m² or even higher has become the standard configuration, ensuring clarity even in strong light. 

Viewing. Meanwhile, the full viewing angle (178°/178°) technology ensures no color bias or distortion when viewed from

 different angles. 

Wide temperature operation capability: The temperature difference in industrial control environments is significant. An 

outstanding industrial control screen must support a wide temperature operating range from -20℃ to 70℃ to prevent 

failure to start due to low temperatures. Or, at high temperatures, there may be screen flickering or trailing images. 

• Extra-long lifespan and reliability: Industrial equipment requires continuous operation 24/7. It adopts industrial-grade

 LED backlighting (with a lifespan of over 50,000 hours) and is equipped with a metal screen. 

The shielding frame is used to enhance the anti-electromagnetic interference (EMI) capability, which is the key to ensuring

the long-term stable operation of the equipment. 

Rich interface configuration: In addition to the traditional LVDS, nowadays, more and more 19-inch industrial control 

screens are beginning to come with eDP (embedded DisplayPort) interfaces as standard. 

It offers higher transmission rates and simpler circuit designs. 

III. Procurement Suggestions: Select the source manufacturer to ensure quality and delivery time. 

When faced with the dazzling array of products in the market, we suggest that purchasers: 

1. Clearly define the application scenario: Determine the screen's brightness, temperature rating, and surface treatment 

(such as anti-glare) based on the specific usage environment of the device (indoor / semi-outdoor, temperature, touch 

requirements). Glare, water resistance. 

2. Verify the qualifications of suppliers: Give priority to original manufacturers that have independent R&D capabilities, 

complete production lines, and strict quality inspection processes. This not only ensures product consistency but also 

enables them to provide reliable support and services. 

Get a quick response for customized requirements (such as interface definition, fine-tuning of structural dimensions). 

3. Focus on Long-Term Support: Industrial control equipment has a long life cycle, and stable supply and long-term 

technical support are of vital importance. Choose a supplier that can offer a commitment to continuous supply and 

professional after-sales service. Being a supplier is the best strategy to avoid the risk of future production halts.
