How to improve the clarity of roll-up LED display?

  Nowadays, roll-up LED display screen as a promotional advertisement, information content playback video of a key medium, for the clarity of the requirements have become more and more high. Its clarity refers to the degree of clarity of the image, text or video displayed on the screen, the better the clarity, the more amazing visual experience can be brought, presenting more realistic content and better visual effects. So do you know how to improveRoll-up LED DisplayThe clarity of the The following Vishay Technology editorial is for you:

  Ways to improve the clarity of roll-up LED displays:

  1、Improve the contrast

  Contrast is one of the key elements affecting the visual effect, generally speaking, the higher the contrast, the clearer and more eye-catching image, the more vivid and colorful. For image clarity, detail expression, gray scale expression are very helpful.

  In some text and video with large black and white contrast, high contrast roll-up LED display has advantages in black and white contrast, clarity, integrity and so on. For dynamic video effect to have a greater impact, due to the dynamic image of light and dark conversion is relatively fast, the higher, the human eye is easier to distinguish such a conversion process. Progress roll-up LED display brightness can reduce the screen surface reflectivity, however, the brightness is not the higher the better, too high, on the contrary, it will be counterproductive, light pollution has become the usual hot topic, too high will have an impact on the environment and the crowd. Full-color LED display panels and light-emitting tubes in a special process disposal, can reduce reflectivity, but also increase the contrast.

  2. Increase the grayscale value

  Gray scale value refers to the screen monochrome brightness from dark to bright between the brightness value can be distinguished, the higher the gray scale value of the roll-up LED display, the more colorful, colorful; On the contrary, the color is single, simple changes. And the increase of grayscale value, can greatly enhance the color depth, make the image display level is a geometric number of increase. LED grayscale control level of 14bit ~ 16bit, make the display product image level resolution details and display effect have arrived at the excellent level. With the development of hardware technology, LED grayscale value will be increased to high control precision.

  3. Reduce the point spacing

  Reduce the dot pitch of the roll-up LED display, can be very good to improve the clarity of the display screen, because the smaller the dot pitch, the higher the pixel density per unit area of the roll-up LED display, more details can be displayed, the more detailed the screen display, the more detailed the screen display, the more detailed and realistic the picture display.

  4. Progress in contrast

  Roll-up LED display screen contrast effect is one of the factors affecting the visual elements, generally speaking, the higher the contrast, the more clear and eye-catching image, the more vivid and colorful. High illuminance on the clarity of the image, detail performance, gray level performance are very helpful.

  To summarize, these are the methods to improve the clarity of roll-up LED display. Ultra HD video often produces a more vibrating visual effect feeling, and we can present more realistic content and better visual effects through these ways to improve the clarity of the roll-up LED display.
