Ultra-Thin Design: Without the need for a backlight, OLED display can be extremely thin and even flexible.
Wide Viewing Angle: Provides consistent color and brightness from any angle.
Fast Response Time: Ideal for displaying dynamic images with no motion blur.
Analogy: It’s like each pixel is a small light bulb that can emit light independently, displaying various colors and brightness without needing an external light source.
Applications: Common in smartphone screens, conference room LED display, tablet, and XR LED screen.
3. Micro LED
3.1 What is Micro LED?
Micro LED is a new type of self-emissive display technology that uses micron-sized (less than 100 micrometers) inorganic LEDs as pixels, with each pixel independently emitting light.
Micro LED Features:
Self-Emissive: Similar to OLED, each pixel emits light independently, but with higher brightness.
High Brightness: Performs better than OLED in outdoor and high-brightness environments.
Long Lifespan: Free from organic materials, thus eliminating burn-in issues and offering a longer lifespan.
High Efficiency: Higher energy efficiency and luminous efficiency compared to OLED and LCD.
Analogy: It’s like a display panel made of countless tiny LED bulbs, each capable of independently controlling brightness and color, resulting in more vivid display effects.
Applications: Suitable for large LED video wall, professional display equipment, smartwatch, and virtual reality headset.

5. How to Choose the Right Display Technology?
Choosing the right display technology starts with understanding the different types of display technologies available. The mainstream display technologies on the market include LCD, LED, OLED, and QLED. LCD is a mature technology with relatively low cost but lacks in color performance and contrast; LED excels in brightness and energy efficiency but still has room for improvement in color performance and contrast; OLED offers excellent color performance and contrast but is more expensive and has a shorter lifespan; QLED improves upon LED technology with significant enhancements in color performance and contrast.
After understanding the characteristics of these technologies, you should choose the one that best fits your needs and budget. If you prioritize color performance and contrast, OLED might be the better choice; if you focus more on cost and lifespan, LCD might be more suitable.
Additionally, consider the size and resolution of the display technology. Different technologies perform differently at various sizes and resolutions. For example, OLED performs better in small sizes and high resolutions, while LCD performs more stably in larger sizes and lower resolutions.
Finally, consider the brand and after-sales service of the display technology. Different brands offer varying quality and after-sales support. RTLED, Well-known LED display screen manufacture in China, provide products with comprehensive after-sales service, ensuring peace of mind during use.
