VATN Alphanumeric Segment LCD Display for Speedometer Odometer Meter with High Contrast, Wide Temperature Range, and Customizable Backlight

The VATN (Vertically Aligned Twisted Nematic) alphanumeric field liquid crystal speedometer and odometer is a segmental digital instrument that employs advanced VA type LCD technology. Its core function is to digitally display the vehicle's speed and mileage.

• Belongs to VA (Vertical Alignment) liquid crystal technology (also known as EBTN / Ultra Dark TN), operating in negative display mode (black background with white text)
• Ultra-high Contrast: Contrast ratio up to 1000:1, far exceeding traditional TN/STN screens with sharp boundaries
• Wide Viewing Angle: Approximately 170° (horizontal) / 110° (vertical) without white or black appearance from driver's side
• Fast Response: Quick liquid crystal molecule flipping for smooth dynamic digital content without ghosting
• Strong Environmental Adaptability: Wide working temperature range (-40°C ~ 85°C) with good readability in strong light, no temperature compensation needed

• Fixed segment code / pen segment design instead of dot matrix
• Main Display Area: 7 segment digits (0-9) for speed (e.g., 188 km/h) and total/cumulative mileage (e.g., 99999.9 km)
• Symbol Area: Fixed icons (km/h, total mileage, TRIP cumulative mileage, gear position, fuel level, warning light, etc.)
• Backlight: Standard high-brightness LED backlight (white/green/yellow/blue selectable) for clear night visibility

• Low power consumption, DC drive, compatible with 12V/24V vehicle power supply
• Receives Hall sensors / rotational pulse signals converted into speed and mileage by internal chip
• Mileage data stored in non-volatile chips (EEPROM), retained when power is off

• Automobile (Modified/Economy Type): Digital speed/mileage area on dashboard or as additional instrument
• Special Vehicles: Forklifts, golf carts, off-road vehicles, agricultural machinery, industrial/engineering vehicles
• Function Expansion: Besides speed/mileage, often integrates display of voltage, water temperature, fuel quantity, speed, time, fault codes

• Clear and Readable: Black background with white text, high contrast, wide viewing angle, clear in bright/dim light
• Stable and Reliable: No mechanical wear, shock-resistant, temperature-resistant, long lifespan
• Precise: Electronic sensing, accuracy within ±0.5%
• Low Cost: Segment code screens cheaper than TFT color screens with simpler driving

No problem. Firstly, please kindly send us your specification/drawing paper. If you don't have the specification, you can also provide your samples; we will recommend the suitable one if it is standard products. Or we can customize for you based on your own requirement.

For the segment type LCD module, if you need to modify the outline size or display content, a new LCD glass module is needed. We have to open new tooling for you.

That's all right. We can change for you as per your request.

Yes, we can. Please send your drawing paper. If you don't have one, please advise the outline size of the LCD display, display information (Glass thickness, Polarizer, Display Type, Connector mode, Storage Temp, Operating Temp, Supply Voltage, Viewing direction, drive condition), we can customize for you.

Generally speaking, it will cost 15 to 25 days after drawing paper confirmation and tooling charge payment. We can report you the exact time when you confirm the drawing paper.

Yes. Samples order is available.

If we have stock for the standard ones, the leading time is one day after payment. If it is the mass production for special ones, the leading time is about 15-30 days. If we can finish earlier, we will report the information in advance.
