  When the user buys the full-color LED advertising screen,it usually requires the LED advertising screen manufacturer to give the relevant technical parameters of the product,which will show the product's gray level,display brightness,product refresh,protection level,unit board size,pixel density and many other technical performance,what is the relationship between the gray level of the full-color LED advertising screen and the display brightness?Today,follow the Chinese Ddon Visual sense to understand:

  1、Gray Level:

  Gray level is a measure of how bright or dim an individual LED pixel on the screen is.It is usually expressed as a numerical value between 0(completely off)and the maximum value(completely on).Each pixel is made up of red,green,and blue sub-pixels,and the combination of the gray levels of these sub-pixels determines the overall color and brightness of the pixel.

  2、Display Brightness:

  Display brightness refers to the overall light output of the entire LED advertising screen.It is influenced by the sum of gray levels of all pixels on the screen.The higher the combined gray levels of all pixels,the brighter the display will appear.

  3、Color Mixing:

  LED screens use a technique called Pulse Width Modulation(PWM)to control the intensity of each sub-pixel(red,green,blue)within each pixel.By adjusting the gray levels of these sub-pixels,various colors can be achieved.For instance,combining full intensity of all three sub-pixels results in white,while turning off all sub-pixels results in black.

  4、Brightness Levels and Color Accuracy:

  Gray levels are essential for achieving accurate color reproduction and smooth transitions between colors.Precise control over gray levels allows the screen to display a wide range of colors with accurate brightness levels.

  5、Dimming and Grayscale:

  LED screens often use grayscale to create smooth transitions between colors.Grayscale refers to the different shades of gray that can be produced by adjusting the gray levels of each sub-pixel.This helps achieve more natural-looking images and videos.

  6、Gamma Correction:

  Gamma correction is a technique used to adjust the relationship between input signal values and the resulting display brightness.This correction helps ensure that the screen displays images with accurate contrast and brightness across different gray levels.
