What are the factors to consider when selecting an LED display?

  As LED displays become more and more widely used, we see and even use them in various scenarios every day.LED displayWith its large screen and high definition resolution, it has become the main display solution to create an immersive scene, and it is also very popular in showrooms, exhibition halls and other scenes. So what are the factors to consider when picking an LED display? The following Vishay editorial will be introduced to you.

  Factors to consider when selecting an LED display:

  1. Brightness

  LED display the same level of brightness from the darkest to the brightest can be distinguished between the brightness level. Gray scale, also known as the color scale or gray scale, refers to the brightness of the degree of light and darkness. For digital display technology, gray scale is the determinant of the number of colors displayed. Generally speaking the higher the grayscale level of the LED display, the richer the color, the more colorful; Conversely, the display color is single, simple changes.

  At present, the domestic LED display mainly uses 8-bit processing system, that is, 256 (28) levels of gray scale. Simple to understand is from black to white there are 256 kinds of brightness changes. Using RGB three primary colors can constitute 256 x 256 x 256 = 16777216 colors. International brand display mainly uses 10-bit processing system, that is, 1024 levels of gray, RGB three primary colors can constitute 1.07 billion colors.

  2. Wavelength

  The wavelength determines the dynamic color gamut range of the display.The three colors of the LED full color display are measured by wavelength. A high quality LED full color display should have a wide color gamut range.

  3. Frequency of frame change

  LED display screen frame information update frequency. Generally 25Hz, 30Hz, 50Hz, 60Hz, etc., the higher the frequency of frame change, the better the continuity of the changing image.

  4. Refresh frequency

  The inverse of the time required to display a frame, the display as a luminous light source, that is, the flicker frequency of the light source. We can use similar "light sensor frequency meter" instrument to directly test the display of the light source flicker frequency, to reflect this indicator.LED display data per second is repeated the number of times. Often 60Hz, 120Hz, 240Hz, etc., so it is necessary to maximize the refresh frequency to ensure the stability of the display screen.

  The above on the selection of LED display to consider what factors are introduced here for you, I hope this article will help you. If there is anything you do not understand you can leave a message to the editor, we will answer for you as soon as possible.
