LEEHON, as a professional industrial-grade LCD screen supplier, is committed to providing customers with high-performance, high-reliability TFT LCD screen solutions to meet the needs of various industrial scenarios.

I: Advantages of TFT LCD Screens

High Reliability and Long Lifespan
Industrial-grade components: Utilizing high-temperature and aging-resistant components, the lifespan typically exceeds 50,000 hours, significantly extending the lifespan of equipment compared to approximately 30,000 hours for ordinary commercial screens.

Wide Temperature Range: Supports operating temperatures from -30℃ to 85℃, far exceeding the 0℃ to 50℃ range of ordinary commercial screens, enabling stable operation in extreme temperature environments such as outdoors and cold storage warehouses.

Vibration/Shock Resistance: Passes industrial-grade vibration testing, suitable for high-frequency vibration scenarios such as automotive and mechanical control systems.

Strong Environmental Adaptability: Dust and Moisture Proof: Utilizes a sealed design or anti-corrosion coating, meeting IP65/IP67 protection standards, effectively preventing dust and liquid intrusion.

Electromagnetic Interference (EMI) Resistance: Optimized circuit design reduces display malfunctions caused by electromagnetic interference from industrial equipment.

High Brightness & Anti-Glare: Brightness reaches 1000~2500 nits, combined with a matte finish, ensuring clear display even in strong light.

Stable Performance and Low Failure Rate: 24/7 Continuous Operation: Supports uninterrupted operation with no risk of screen burn-in.

Wide Voltage Input: Adapts to 9V~36V DC voltage fluctuations, offering greater adaptability compared to the 12V of ordinary commercial screens.

Modular Design: Facilitates maintenance, allowing for quick replacement of components such as backlights and driver boards.

High-Performance Display: High Resolution and Color Reproduction: Supports high-resolution displays, such as 720P/1080P, with high color reproduction up to 16.7M colors (24-bit color), capable of presenting richly detailed images.

High-Performance Display: High resolution and color reproduction: Supports high-resolution displays, such as 720P/1080P, with high color reproduction up to 16.7M colors (24-bit color), capable of presenting richly detailed images. Wide Viewing Angle: Utilizing IPS and other technologies, it achieves a wide viewing angle of 170° or even 178°, avoiding color distortion caused by viewing angle deviation.

Fast Response Speed: Suitable for displaying dynamic images (videos, animations), reducing ghosting.

Cost-Effectiveness and Customization

Cost-Effectiveness: TFT-LCD technology is mature, with complete production lines and low manufacturing costs. It offers multiple sizes and resolutions, providing a price advantage for bulk purchases.

Customization Services: Supports flexible customization of size, brightness, resolution, etc. Resolution (e.g., 1024×768 to 4K), size (5~85 inches), and backlight type (LED/CCFL) can be adjusted to meet the specific needs of different customers.

II: FAQ

Q1: What is a TFT LCD screen?

A1: TFT LCD screen stands for Thin Film Transistor Liquid Crystal Display, a type of active matrix LCD. Each pixel is controlled by an independent thin-film transistor, resulting in clear images, fast response speed, and high color reproduction.

Q2: What is the difference between a TFT LCD screen and a regular LCD?

A2: Ordinary LCDs (such as TN/STN) use passive matrix driving, which is prone to slow response, image retention, and poor contrast. TFT LCD screens, on the other hand, use active matrix driving, with pixels independently switched by transistors, providing higher resolution, more stable images, and faster refresh rates.

Q3: How many colors can a TFT LCD screen display?

A3: TFT screens typically offer color depths of 16-bit (65K colors), 18-bit (262K colors), and 24-bit (16.7M colors). High-end TFT screens support 24-bit true color display, capable of presenting richer color transitions and details.

Q4: In which fields are TFT LCD screens mainly used?

A4: Due to their stable performance and controllable cost, TFT LCD screens are widely used in consumer electronics (mobile phones, tablets, TVs), automotive instruments, industrial control equipment, medical displays, measuring instruments, and many other fields, making them the most popular type of display screen currently.
