What is the difference between LED and OLED display?

As an OLED monitor lights individual pixels, rather than relying on a backlight, these pixels can be turned off entirely, and this produces a pure black color and a higher contrast with white. The backlighting in LED monitors means they cannot block light out entirely.LED and OLED are two different display technologies used in electronic devices. Here's a brief explanation of the differences between them:

LED (Light-Emitting Diode) Display: LED displays consist of an array of small light-emitting diodes. These diodes emit light when an electric current passes through them. LED displays can be further categorized into two types: LED-back lit LCD and Micro LED.

LED-back lit LCD: In this type, an LCD panel is used as the base, and an array of LEDs is placed behind the panel to provide the light source. The LEDs are used to illuminate the LCD pixels, which control the light passing through to create the image.

MicroLED: Micro LED is a newer technology that uses an array of microscopic LEDs to create the display. Each LED emits its own light, which allows for precise control over individual pixels. MicroLED displays are known for their high brightness, excellent contrast, and wide color gamut.

OLED (Organic Light-Emitting Diode) Display: OLED displays are made up of organic compounds that emit light when an electric current is applied. Unlike LED displays, OLEDs do not require a separate back lighting system. Each pixel in an OLED display emits its own light independently.

OLED displays offer several advantages over LED displays:

Better contrast: OLEDs can produce deep blacks because each pixel can be turned off completely, resulting in infinite contrast ratios.

Faster response time: OLEDs have faster response times, which means they can display fast-moving content without motion blur.

Thinner and lighter: OLED displays can be made thinner and lighter because they don't require a separate backlight.

Wide viewing angles: OLEDs provide excellent viewing angles with consistent image quality from different angles.

However, OLED displays also have some limitations, including potential issues with burn-in (permanent damage caused by static images displayed for long periods) and shorter overall lifespan compared to LED displays.

In summary, LED displays are based on traditional LCD technology with LED back lighting, while OLED displays are self-emissive, meaning each pixel emits its own light. OLED displays generally offer better contrast, faster response times, and wider viewing angles, while LED displays are more widely used and have longer lifespans.
