the difference between LED and OLED technology

At Mildtrans Laptop Foreign Trade Company, our colleagues shared the difference between LED and OLED technology at the morning meeting today, which is crucial for product promotion and customer service.

The following is a concise knowledge summary about LED and OLED:

The difference between LED and OLED display technology

1. Basic concepts:

LED (Light Emitting Diode):

LED actually refers to a light-emitting diode technology. LED screens are usually the backlight source of LCD screens. It emits light through the backlight source to illuminate the liquid crystal layer to form an image.

OLED (Organic Light Emitting Diode):

OLED is a self-luminous technology, and each pixel is able to emit light independently. It consists of layers of organic compounds that emit light when powered on, directly generating images.

2. Display quality:

LED:

Contrast: LED screens have lower contrast because the backlight of the liquid crystal layer may affect the depth of black.

Brightness: Generally, LED screens have higher brightness and are suitable for use in bright environments.

Color: LED screens have better color performance, but the color authenticity and vividness are slightly inferior to OLED.

OLED:

Contrast: OLED screens have extremely high contrast because each pixel emits light independently, which can achieve true black.

Brightness: OLED screens may not be as bright as LEDs, but they perform better in dark environments.

Color: OLED screens are able to provide a wider color gamut and higher color saturation, and the image is more vivid.

3. Power consumption and battery life:

LED:

Power consumption: LED screens have relatively low power consumption at all brightness settings.

Battery life: For laptops, LED screens generally provide longer battery life.

OLED:

Power consumption: The power consumption of OLED screens depends on the displayed content. When displaying black or dark content, the power consumption is lower; when displaying bright content, the power consumption is higher.

Battery life: The battery life of OLED screens may vary depending on the content.

4. Response time and viewing angle:

LED:

Response time: Generally slower, which may affect the clarity of dynamic images.

Viewing angle: The viewing angle is narrow, and the color and brightness will be biased when viewed from the side.

OLED:

Response time: Very fast response time, suitable for displaying fast dynamic scenes.

Viewing angle: Very wide viewing angle, consistent image quality from almost any angle.

5. Lifespan and burn-in issues:

LED:

Lifespan: LED backlights have a long lifespan, usually lasting for many years.

Burn-in: No burn-in issue.

OLED:

Lifespan: OLED's organic materials degrade over time, so their lifespan is relatively short, especially for blue organic materials.

Burn-in: OLED screens may experience burn-in, a problem of static image retention.

6. Cost:

LED:

Cost: Relatively low production cost, more competitive price.

OLED:

Cost: High production cost, so the price is usually more expensive.

Summary:

LED is suitable for scenarios that require high brightness, long battery life and low cost.

OLED is suitable for scenarios that require higher contrast, color performance and wide viewing angle, but it is more expensive.

Understanding these differences can help us better recommend laptop display technology to customers in the future to suit their needs. Provide customers with a one-stop shopping service for better quality laptop accessories.
