Three tips to double the clarity of outdoor LED displays_u200bOutdoor LED Display|Outdoor Large Screen Size

If the display effect of the outdoor LED display is not clearer, it will directly affect the overall effect of the LED display. So how can we make the LED display more clearly displayed outdoors? The contrast, refresh rate, gray level and other technical indicators of the full-color LED display directly affect the display effect of the full-color LED display. 1. Contrast improvement Contrast is one of the key factors that affect the visual effect. Generally speaking, the higher the contrast, the clearer the image and the brighter the color. High contrast is very helpful for image clarity, detail performance, and gray level performance. In some text and video displays with large black-and-white contrast, high-contrast LED displays have advantages in black-and-white contrast, clarity, and integrity. Contrast has a greater impact on the dynamic video display effect. Because the light-dark transition in the dynamic image is faster, the higher the contrast, the easier it is for human eyes to distinguish such a conversion process. Two, two main methods to improve the contrast of the display screen 2. Reduce the reflectivity of the LED display surface The main method is to perform special processing on the LED panel and LED light-emitting tube to reduce the reflectivity of the LED panel, thereby improving the contrast of the LED display screen. The NX series LED full-color high-end display with a dot pitch of 4mm has increased from 950:1 of the original process to 4000:1, which greatly improves the product's key index of contrast. 1. Improve the brightness of the LED display In some occasions, the higher the brightness of the LED display, the better. For example, if the brightness of an indoor display is too high, light pollution will be formed, which will damage the eyesight of the observer. 3. Gray level Gray level refers to the brightness level that can be distinguished from the darkest to the brightest in the single primary color brightness of the LED display. The higher the gray level of the outdoor LED display, the richer the color and the brighter the color. ; On the contrary, the display color is single and the change is simple. The increase of the gray level can greatly increase the color depth, making the display level of the image color increase geometrically. The LED gray scale control level is 14bit~16bit, making the image level resolution details and display effects of high-end display products reach the world's advanced level. With the development of hardware technology, LED gray scale will continue to develop to higher control accuracy.
