Display Modules - LCD, OLED, Graphic

1. Overview

Optoelectronics display modules are electro-optical devices that convert digital signals into visual information. LCD (Liquid Crystal Display), OLED (Organic Light-Emitting Diode), and Graphic modules represent three core technologies in modern display systems. These modules enable human-machine interaction in applications ranging from consumer electronics to industrial automation, with advancements driving thinner form factors, lower power consumption, and higher visual fidelity.

2. Major Types and Functional Classification

TypeFunctional FeaturesApplication Examples
LCDBacklit liquid crystal layer, requires polarizers, moderate power consumptionSmartphones, TVs, automotive dashboards
OLEDSelf-emissive organic materials, infinite contrast ratio, flexible variantsSmartwatches, VR headsets, premium smartphones
GraphicFixed pixel matrix for icons/symbols, low resolution but high reliabilityIndustrial equipment, medical devices, vending machines

3. Structure and Components

LCD: Composed of backlight unit (LED/CCFL), liquid crystal layer, color filters, and TFT (Thin-Film Transistor) array. Polarizing films on both sides control light transmission.

OLED: Contains anode/cathode layers with organic emissive materials (small molecules or polymers) sandwiched between. Utilizes encapsulation layers to prevent moisture damage.

Graphic Modules: Simplified structure with segmented electrodes and passive matrix addressing, often using monochrome STN (Super-Twisted Nematic) technology.

4. Key Technical Specifications

ParameterDescriptionImportance
Resolution (ppi)Pixels per inch determining image sharpnessHigher values provide clearer visuals
Luminance (cd/m )Brightness level sustainabilityImpacts outdoor visibility
Response Time (ms)Pixel switching speedPrevents motion blur in dynamic content
Operating Temperature ( C)Functional temperature rangeDetermines environmental adaptability
Lifespan (hours)Half-brightness duration100,000 for LCD, 50,000 for OLED

5. Application Areas

  • Consumer Electronics: Smartphones (OLED), tablets (LCD)
  • Medical Equipment: Diagnostic monitors (LCD), portable devices (Graphic)
  • Automotive: Instrument clusters (OLED), infotainment systems (LCD)
  • Industrial HMI: Control panels (Graphic), automation systems (LCD)
  • AR/VR: High-speed OLED microdisplays

6. Leading Manufacturers & Products

LG DisplayLCDIPS panels for Apple iPad Pro
SharpGraphicLS013B7DH01 memory LCD
BOE TechnologyAll Types10.7" flexible AMOLED for wearables

7. Selection Guidelines

Consider these factors for optimal selection:

  • Application Scenario: Outdoor use requires high brightness ( 1000 cd/m )
  • Power Budget: OLED consumes 30% less power than equivalent LCD in dark content
  • Environmental Conditions: Industrial-grade (-30 C to +85 C) for automotive systems
  • Cost Constraints: Graphic modules cost 40-60% less than color TFT LCDs
  • Integration Complexity: OLED requires built-in compensation circuits for aging effects

Case Study: A smartwatch design selected 1.4" AMOLED module for its 1000:1 contrast ratio and 0.1mm ultra-thin profile despite higher cost.

8. Industry Trends

Key development directions include:

  • Micro-LED adoption for >3000 cd/m brightness and sub-10 m pixel pitch
  • Rollable OLED with improved encapsulation technology
  • AI-driven display compensation algorithms for uniformity enhancement
  • Low-temperature polycrystalline oxide (LTPO) backplanes for dynamic refresh rates
  • Biodegradable substrate materials for eco-friendly modules
