The difference between LED display and OLED display.

Many users are not aware of the differences between LED advertising screens and OLED advertising screens. Although there is only a one-letter difference, these two products are entirely different. They differ in terms of their lighting principles, display effects, application scenarios, and pricing. Today, with LED advertising screen manufacturer China Ddon Visual, let's explore the differences between LED advertising screens and OLED advertising screens:

1、Lighting Principle:

LED Advertising Screen: LED advertising screens use LEDs as a backlight source to illuminate the LCD (Liquid Crystal Display) to generate images. LED advertising screens are typically a part of LCD displays, and the light source is provided by the backlight unit.

OLED Advertising Screen: Each pixel in an OLED advertising screen is an independent organic light-emitting diode (OLED) that can emit light directly. Each pixel can be controlled independently, and there is no need for a backlight unit. Therefore, OLED advertising screens are usually thinner and can achieve deeper blacks and higher contrast.

2、Contrast and Color Representation:

LED Advertising Screen: LED backlighting restricts the contrast and black levels of LCD displays. While there are advanced LED backlighting technologies like Full Array Local Dimming (FALD), it is still challenging to match OLED in this regard.

OLED Advertising Screen: OLED advertising screens offer outstanding contrast and color representation. Because each pixel can be controlled independently, OLED can achieve true deep blacks and vibrant colors while avoiding issues like light bleeding and the "halo effect."

3、Viewing Angle:

LED Advertising Screen: LCD displays with LED backlighting may exhibit color shifting and reduced brightness at wide viewing angles.

OLED Advertising Screen: OLED advertising screens have a wider viewing angle, and the image remains consistent at various angles.

4、Energy Efficiency:

LED Advertising Screen: LED backlighting technology can be energy-efficient, especially in the case of Direct-lit or Edge-lit LED backlighting.

OLED Advertising Screen: OLED advertising screens consume less power when displaying black pixels but consume more power when displaying bright pixels.

5、Lifespan:

LED Advertising Screen: LED backlighting typically has a relatively long lifespan, lasting for several years.

OLED Advertising Screen: Organic materials in OLED advertising screens degrade over time, leading to uneven brightness and color. This means OLED advertising screens may develop "burn-in" or "image retention" issues after several years, especially when displaying the same image continuously.

In summary, LED advertising screens and OLED advertising screens differ significantly in terms of their lighting principles, contrast, viewing angles, energy efficiency, and lifespan. LED advertising screens are more commonly used in large-area display projects such as outdoor advertising, canopies, and stage backdrops. On the other hand, OLED advertising screens are predominantly used in handheld terminal devices like mobile phones, laptops, smartwatches, and other industries. The above analysis highlights the differences between LED advertising screens and OLED advertising screens. We hope this article has been helpful.
