LED Display Faqs

Common Indicators of LED Display

Resolution

Definition: The number of pixels displayed on the screen, usually expressed as horizontal pixels x vertical pixels

Brightness

Definition: The intensity of light emitted per unit area, usually measured in nits

Contrast Ratio

Definition: The ratio of the luminance of the brightest white to the darkest black

Refresh Rate

Definition: The number of times the display refreshes the image per second, usually measured in Hertz(Hz)

Color Performance

Definition: The number of colors the display can show and the accuracy of these colors

Viewing Angle

Definition: The maximum angle at which the image quality remains consistent when viewed from different directions

Response Time

Definition: The time it takes for the display to switch from-one image to another, usually measured in milliseconds(ms)

Lifespan
