OLED Explained: The Light Revolution

OLED Technology

The future of display technology that's thinner, brighter, and more efficient

What is OLED?

OLED (Organic Light-Emitting Diode) is a display technology where each pixel emits its own light. Unlike LCDs that require a backlight, OLED pixels illuminate individually, enabling perfect blacks and infinite contrast.

The "organic" in OLED refers to carbon-based molecules that emit light when electricity is applied. This revolutionary approach allows for thinner, more flexible displays with superior image quality.

Key Advantage

OLED displays can turn off individual pixels completely, achieving true black and saving energy when displaying dark content.

How OLED Works

1

Organic Layers

OLED displays consist of organic material layers sandwiched between two electrodes. When voltage is applied, these layers emit light.

2

Pixel Control

Each pixel contains red, green, and blue subpixels that can be individually controlled for brightness and color accuracy.

3

Self-Illumination

Unlike LCDs, no backlight is needed. Pixels emit their own light when activated, allowing for thinner displays and better energy efficiency.
