What is the difference between LCD and OLED

The difference between LCD and OLED

LCD (liquid crystal display) and OLED (organic light-emitting diode display) are two different display technologies with different advantages and disadvantages:

Display principle

• LCD: Use liquid crystal crystal to modulate the backlight, change the direction of the backlight through the rotation direction of the liquid crystal box, and then control each The color and brightness displayed by each pixel.
• OLED: Using self-luminous diodes, organic materials emit light when a current is applied to OLED pixels.

Contrast and Color

• LCD: Contrast is not as good as OLED because the backlight will penetrate the liquid crystal layer, resulting in a black look It looks dark.
• OLED: Has infinite contrast because each pixel can be turned off completely, producing perfect blacks. In addition, OLED has a wider color gamut and can display richer colors.

Brightness and viewing angles

• LCD: Typically brighter than OLED, especially with strong backlighting.
• OLED: With wider viewing angles, there will be no obvious color distortion when viewed at any angle.

Energy consumption

• LCD: Requires a continuous backlight and therefore consumes more power than OLED.
• OLED: Only consumes energy when displaying pixels, so power consumption is lower, especially when displaying dark images.

Response time

• LCD: Slow response time, which may cause motion blur.
• OLED: Extremely fast response times and virtually no motion blur.

Application scenarios

• LCD: Suitable for applications requiring high brightness and wide display range, such as TVs and monitors .
• OLED: Ideal for applications where contrast, color accuracy, low power consumption and flexibility are important, such as smartphones, watches and laptops.
