There are several types of outdoor LED sign by considering their colors, such as Monochrome LED Sign, dual LED Sign, Full Color LED Sign, etc. You may use them to present simple characters, images or commercial videos for your small. But generally speaking, in order to them to show clearly seen and vivid images issue what kind of sign they are. Here are a handful tips to achieve that:
1. Adjust the gray level. Gray level is the brightness of any LED pixel. The value associated using a pixel representing it's lightness from black to white, usually thought a value from 0 to 255, with 0 being black and 255 being white, so this means the higher gray level is, the richer the colours are. Raising the gray level in a number of scale can highly improve the image quality showing on the LED sign regardless of what type of LED display you are receiving. Even in the single color LED sign, high gray level generates the color gradation much richer and also the image more tri-mensional.
2. Enhance the contrast. Higher contrast means higher color saturation, often a better choice to an increasingly vivid and clearer visual affect. High contrast will be sufficient a lot to improve the clarity, detail performance and grey level on the image. In some texts and videos that have a large black-white contrast, the high contrast LED display may have an advantage on the black-white contrast, definition and completeness. Even the contrast capabilities large relation to the presentation of motion videos.
3. Use black LEDs if it is a 3 in 1 SMD display. While always see, the traditional 3 in 1 SMD use white LEDs when you in order to make your 3 in 1 outdoor LED sign show with much higher contrast images, it can be a good option to use black Led lights. The effect associated with the method can be the similar to the second method mentioned above, will be to boost contrast. The standard LED display can look unclear and overexposure when it is viewed for a big viewing angle and taking advantage of black LEDs can solve this problem easily create the sign look clear while being viewed from each less advertised.
