When you get a quotation for an عرض الصمام and see “contrast” in the detailed parameter list, what is the contrast? What does it have to do with the LED display? Let’s find out!

1. What is contrast?

The contrast ratio refers to the maximum difference between the brightness intensity in the white and black ranges.

The contrast ratio is expressed as an X:1 ratio, an LED display that provides the absolute difference between the brightest white and the darkest black.

The stronger the mid-tones are produced, the higher the contrast ratio, which provides better picture smoothness and richer color.

2. What is the difference between real contrast and dynamic contrast?

True contrast measures the difference between instantaneous black and white pixels, usually a small number (800:1, 1000:1, 1600:1, …).

If your screen is mainly used for still pictures, such as photo editing, graphic design, etc., you need to know these important numbers; for example, modern computer LCD monitors are usually 1000:1, and TVs may exceed 4000:1.LED displays can play video, text, pictures, and especially video.

Dynamic contrast is a convenient metric used by manufacturers to measure how much pixel changes from black to white (or gray) over some time; it helps predict the quality of contrast moving images.
