Qtenboard LCD Technology Guide

ការ ណែនាំ

Liquid Crystal Display (LCD) technology is the most mature, reliable, and widely adopted large-format display solution in the world. Across education technology, corporate collaboration, smart governance, digital signage, and modern healthcare, LCD has become the core visual standard.

As one of the global manufacturers of interactive display devices, QtenboardComment has been deeply involved in LCD application, structural optimization, system integration, and durability engineering. With a strong supply chain, advanced optical design capabilities, and highly stable manufacturing processes, Qtenboard LCD modules have become the central display equipment in classrooms, meeting rooms, and collaborative workspaces around the world.

1. Basic Principles of LCD Technology (Qtenboard Manufacturing Standards)

LCD (Liquid Crystal Display) controls the rotation of liquid crystal molecules to allow or block light. Since liquid crystals themselves do not emit light, LED backlights provide illumination, while polarizers, color filters, and TFT arrays create the final visual output.

In Qtenboard’s LCD display modules, the structure typically includes:

• Premium polarizers
• Qtenboard-selected liquid crystal materials
• High-brightness LED backlight
• RGB color filters
• High-speed TFT array
• Optical diffusion and light-guiding layers
• Qtenboard–selected driver IC solutions

These components are strictly chosen by Qtenboard’s engineering team to ensure every interactive display delivers:

• High brightness
• Uniform color performance
• Long operational lifespan
• Low power consumption
• Stable 7×24 operation

2. LCD Technology Categories & Key Industry Terms (Qtenboard Standards)

LCD technologies are divided into two major categories: PM (Passive Matrix) and AM (Active Matrix).

Within Qtenboard’s product ecosystem:

• PM is used for small-size industrial or instrument applications
• AM (TFT-LCD) is the dominant technology for Qtenboard’s interactive whiteboards, meeting displays, and signage products

AM LCD offers superior color accuracy, wider viewing angles, better brightness, and faster response time—making it the best option for large interactive screens.

3. PM (Passive Matrix) LCD Technology

While Qtenboard focuses mainly on large AM LCD panels, PM LCD still plays a role in low-power industrial devices.

ប្រភេទ@ info: whatsthis	លក្ខណៈ ពិសេស
TN	Low cost, mature manufacturing
HTN	Improved contrast
STN	Better clarity
FSTN	Excellent black-and-white performance
WVTN	Improved viewing angles
VA	Superior black levels

Qtenboard uses PM LCD only for specific industrial solutions—not for interactive whiteboards or meeting displays.

4. AM (Active Matrix) LCD Technology – Qtenboard’s Core Technology

All Qtenboard interactive displays use AM LCD (TFT-LCD), including:

• Education interactive whiteboards
• Business meeting displays
• Digital signage
• Medical information screens
• Touch collaboration devices

Common AM LCD types:

ប្រភេទ@ info: whatsthis	លក្ខណៈ ពិសេស
IPS	Ultra-wide viewing angle, accurate colors — Qtenboard’s top choice for education
FFS	High brightness, low power — widely used in Qtenboard signage
VA	High contrast, stable dark performance
ASV	Uniform brightness and excellent color depth
AIFF MVA	High-end application technology, used in Qtenboard custom projects

Qtenboard’s AM LCD Optimizations

• 178° ultra-wide viewing angle
• 350–450 nits high-brightness design
• Highly stable TCON driver solution
• Low blue light for eye protection
• Anti-glare glass
• Zero bonding for better touch precision

5. Key LCD Peripheral Components (Qtenboard Engineering Standards)

High-quality displays require reliable components. Qtenboard uses industrial-grade materials across all products:

All materials undergo Qtenboard’s laboratory-level testing: high temperature, low temperature, humidity, drop, static electricity, and aging tests—ensuring long-term stability worldwide.

6. LCD Applications in Qtenboard Interactive Whiteboards

Qtenboard interactive displays are widely used in global education and business markets. Their advantages come from the combination of high-quality LCD technology and Qtenboard’s self-developed intelligent systems.
