A few tips to make the LED display clearer

　　‍LED displays can be divided into many types, such as: led unit board, single-color LED display, two-color LED display, inkjet screen, LED full-color display, etc.

　　If the display effect of the LED display is not clearer, it will directly affect the overall effect of the LED display. So how do we make the display of the LED display clearer? Let the LED display experts give you advice.

　　The level of technical indicators such as gray scale, contrast, and refresh rate of the LED full-color display directly affects the display effect of the LED full-color display. The gray level refers to the brightness series 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 LED display, the richer the color and the more gorgeous the color; otherwise, the display color is single , the change is simple. The improvement of the gray level can greatly enhance the color depth, so that the display level of the image color increases geometrically. The LED grayscale control level is 14bit~16bit, which makes the image level resolution details and display effect of high-end display products reach the world's advanced level. With the development of hardware technology, LED gray scale will continue to develop towards higher control precision.

　　Contrast is one of the key factors that affect visual effects. 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 display effect of dynamic video. Since the light and dark transitions in dynamic images are relatively fast, the higher the contrast, the easier it is for human eyes to distinguish such a transition process.

　　There are two main ways to increase display contrast:

　　(1) Improve the brightness of the led display

　　In some occasions, the brightness of the LED display is not as high as possible. For example, indoor display screens, if the brightness is too high, light pollution will be formed, which will damage the eyesight of the observer.

　　(2) Reduce the reflectivity of the LED display surface

　　It is mainly to carry out special process treatment 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. The NX series LED full-color high-end display screen with a dot pitch of 4mm has been improved from 950:1 in the original process to 4000:1, which has greatly improved the key indicator of the contrast ratio of the product.
