Optical Enhancements

The NL8060BC21-11 incorporates an advanced polarizer with anti-glare (AG) and anti-reflection (AR) coating, reducing surface reflection from 16% to under 5%. This improves readability in brightly lit factory floors. The typical transmittance is 6.5%. The LCD uses a normally white mode with a 6-bit FRC (Frame Rate Control) driver to display 262,144 colors, with dithering for smooth gradients.

Electrical and Timing Specifications

Logic supply voltage: 3.3V ±5% (1.5W max). The LVDS interface operates at 35 MHz typical clock frequency, with data mapping following Open LDI standards. The module provides a built-in timing controller (TCON) with spread spectrum clocking to reduce EMI. For power sequencing, the LVDS signals must be applied after VDD stabilizes, with a minimum delay of 10 ms before enabling the backlight.

Backlight Driver and Dimming

The NL8060BC21-11 includes an integrated LED driver that accepts a 12V DC input. Dimming can be controlled via an external PWM signal (1 kHz – 10 kHz) applied to the dedicated pin. The dimming range is from 5% to 100% with linear response. The driver includes open-LED and short-circuit protection. Typical backlight power consumption is 3.6 W at full brightness.

Mechanical Mounting and Reliability

The module is equipped with six M2.5 threaded mounting holes on the rear frame. A removable metal shield covers the driver PCB to prevent accidental contact. The LCD meets IEC 60068-2-64 vibration (2.5g RMS, 10–200 Hz) and IEC 60068-2-27 shock (50g, 11ms half-sine). The polarizer is scratch-resistant (hardness 3H).

Compatible Controllers and Accessories

Common host interfaces include Advantech, Kontron, and Axiomtek single-board computers with LVDS outputs. For development, NLT offers an evaluation kit (part number NL8060BC21-11-EVK) that includes an LVDS cable, inverter board, and touch panel overlay (optional). Capacitive and resistive touch panels with I²C or USB interfaces can be bonded to the front surface.

Applications

Typical applications include CNC machine displays, test equipment HMIs, medical vital signs monitors, marine chart plotters, and security system terminals. The 4:3 aspect ratio is particularly preferred in legacy medical devices.

Storage and Handling

Store the LCD in a clean, dry environment (15°C – 35°C,<70% RH) with the original packaging. Avoid exposure to ultraviolet light and corrosive gases. The polarizer surface is sensitive to sharp objects; never touch it directly with tools. Use only recommended cleaning agents (IPA or ethanol).

Conclusion

The NLT NL8060BC21-11 combines excellent optical performance, robust construction, and long product lifecycle, making it a trusted choice for demanding industrial display applications.
