As the main carrier of advertising and information broadcasting, full-color LED display is more and more closely following the trend of the times. High-definition video can often bring people more and more shocking visual experience, and the displayed content will become more and more realistic.

There are two elements to accomplishing a high-quality display. One is that the film source needs to be full HD, and the other is that the display can support full HD. The full-color LED display is actually adding clarity. So, how can we make the screen clearer? Here, the editor of Liancheng makes a rough analysis

1. Contrast of full-color LED display

Contrast is one of the key factors affecting visual effects. In general, the higher the contrast, the sharper the image and the more vivid the colors. It is very helpful for image clarity, detail expression and grayscale expression.

In some texts and videos with large black and white contrast, the high-contrast LED full-color display has advantages in black and white contrast, sharpness, and integrity. It has a greater impact on the effect of dynamic video. Because the faster and higher the light-dark transition in dynamic images, the easier it is for the human eye to discern this transition process. Increasing the brightness of the full-color LED display can reduce the surface reflectivity of the screen, but the brightness should not be as high as possible, and it will be counterproductive if it is too high. Light pollution has always been a hot topic, and high levels can have an impact on the environment and people. The panel and LED of the full-color LED display have a special process, which can reduce the reflectivity and increase the contrast ratio.

Second, the value of grayscale

The gray value refers to the brightness value of a single primary color of the screen that can be distinguished from dark to bright. The higher the gray value of the full-color LED display, the richer and brighter the color. On the contrary, the color is single and the change is simple. The increase of the value can greatly improve the color depth, so that the display level of the image increases geometrically. The level of LED grayscale control is 14bit~16bit, which makes the image-level resolution details and display effects of high-end display products reach an excellent level. With the development of hardware technology, LED gray value will increase with high control precision.

Third, reduce the spacing

The smaller the distance between the full-color LED displays, the finer the picture. This requires mature technology as the central support, the investment cost is relatively large, and the price of full-color LED display is also high, but fortunately, the market is also developing towards small-pitch LED display.

Fourth, improve the contrast of the full-color LED display

The key to the contrast effect is to influence one of the visual elements. Generally speaking, the higher the contrast, the sharper the image and the more vivid the colors. High contrast is very helpful for image clarity, detail expression and grayscale expression.

In some texts and videos with high black and white contrast, the high-contrast full-color LED display has advantages in black and white contrast, clarity and integrity. Certain lighting has a great influence on the display effect of dynamic video. Because the transition between light and dark in dynamic images is quite fast, the higher the contrast, the easier it is for the human eye to distinguish this transition. In fact, the improvement of the contrast ratio of the full-color LED display is mainly to improve the brightness of the full-color LED display and reduce the external reflectivity of the screen. However, the brightness should not be as high as possible, too high, it will be counterproductive. Light pollution has always been a hot topic. Excessive brightness will affect the environment and people. The full-color LED display LED panel and LED light-emitting tube are specially treated, which can reduce the reflectivity of the LED panel and improve the contrast of the full-color LED display.

Fifth, improve the grayscale of the full-color LED display

Grayscale refers to the brightness series that can be distinguished from the darkest to the brightest in the single primary color brightness of the full-color LED display. The higher the grayscale of the full-color LED display, the richer and brighter the color. On the contrary, the display color is single and the change is simple. The increase of gray scale can greatly improve the color depth, so that the display level of the image color increases geometrically. The level of LED grayscale control is 14bit~16bit, which makes 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, the gray level of LED will be extended to higher control precision from time to time.

Sixth, reduce the dot pitch of the full-color LED display

Reducing the dot pitch of a full-color LED display can improve its clarity. The smaller the dot pitch of the full-color LED display, the more delicate the picture appears. However, this must be supported by mature technology. Its investment cost is relatively large, and the price of full-color LED display is also high. Fortunately, the market is also developing towards fine-pitch LED displays.
