How is the sharpness adjusted on roll-up LED displays?

  With the rapid development of the information age, roll-up LED display development so far, has become the main carrier of advertising and information broadcasting, there is a large alternative to the projector, DLP, LCD and other equipment, the momentum of the future market mainstream products. However, the roll-up LED display after a long time of use, there will inevitably be a lack of clarity, then you need to adjust the clarity. ThenRoll-up LED DisplayHow is the clarity adjusted? The following Vishay Technology editorial is for you:

  The method of adjusting the sharpness of the roll-up LED display:

  1. Contrast

  Contrast is one of the key factors affecting the visual effect of the roll-up LED display, generally speaking, the higher the contrast, the clearer and more eye-catching image, the more vivid and colorful. We can improve the brightness of the roll-up LED display and reduce the screen surface reflectivity, but the brightness should not be too high, otherwise it will affect the service life of the roll-up LED display.

  2. Gray scale level

  Gray level refers to the roll-up LED display single-color brightness from dark to bright can be distinguished between the number of brightness levels, roll-up LED display gray level the higher, the richer the color, the more colorful; Conversely, the display of a single color, the change is simple. Therefore, improve the grayscale can also improve the clarity of the display screen. This indicator belongs to the hardware decision, this point requires us to buy roll-up LED display must look good.

  3. Reduce the point spacing

  Reducing the pitch of the dot roll-up LED display can well improve its clarity, the smaller the dot pitch of the roll-up LED display, the more delicate its picture display. Because the cost of small pitch display is a little higher, so this is a point we need to consider at our discretion.

  In summary, this is the method of adjusting the clarity of the roll-up LED display. In addition to the above methods, we can also use the video processor image scaling processing algorithms to ensure that the video image is scaled so as to maintain the clarity of the image and the gray level of the image brightness, contrast, grayscale, to ensure that the screen of the roll-up LED display can effectively output soft and clear picture.
