The difference between OLED and VA

Blaze Display Technology Co., Ltd. | Updated: Nov 27, 2018

There are differences between OLED and VA in contrast, color gamut, response time, blue light radiation and viewing angle.

1.      Contrast

OLED screens have a higher contrast ratio because they use self-illumination and do not require a backlight. This means OLED is able to achieve deeper blacks and more vivid colors, making image displays more vivid and realistic. In comparison, VA screens have a lower contrast ratio, which can cause images to appear darker or colors to be less saturated.

2.      Color gamut

The OLED screen has a wider color gamut and can display more colors, making the image display more detailed and realistic. The color gamut of VA screens is relatively narrow, which may affect the color performance of images.

3.      Response time

OLED screens have faster response times, which means they can display dynamic images faster without blurring or smearing. VA screens have a slower response time, which may have some impact on viewing rapidly changing images.

4.      Blue light radiation

OLED screens have lower blue light emissions, which can reduce eye irritation and help protect eye health. VA screens have relatively high levels of blue light radiation, which may have some impact on eye health when viewed for long periods of time.

5.      Viewing angle

VA screens have a wide viewing angle, which means you can view the screen from a wider angle without affecting image quality. In comparison, OLED screens have smaller viewing angles, which may degrade image quality when viewed from the side.


Overall, OLED screens may be better in terms of color performance, contrast and response speed, while VA screens have advantages in cost and viewing angles.
