Essential elements for improving clarity of small pitch LED displays
As the main carrier of advertising and information playback, full-color small pitch LED displays are increasingly following the trend of the times in contemporary times. High definition led videos often bring people a more stunning visual experience, and the content displayed will also be more authentic. There are two influencing factors to achieve high-definition display: first, the source requires full HD, and second, the display requires support for full HD. Full color small pitch LED displays are actually moving towards higher definition displays. So, how can we make full color small pitch LED displays clearer?
1、 Improve the contrast of full-color small pitch LED display screens
Contrast is one of the key factors affecting visual effects. Generally speaking, the higher the contrast, the clearer and more eye-catching the image, and the brighter and more vibrant the colors. High contrast is of great help for image clarity, detail representation, and grayscale level representation. The contrast ratio of Lianjian small pitch LED display can reach 5000:1. In some text and video displays with high black and white contrast, high contrast full-color LED display has advantages in black and white contrast, clarity, integrity, and other aspects. Contrast has a greater impact on the display effect of dynamic videos. Due to the fast transition between light and dark in dynamic images, the higher the contrast, the easier it is for the human eye to distinguish this transition process. In fact, the improvement of contrast in full-color LED displays is mainly to increase the brightness of the full-color LED display and reduce the surface reflectivity of the screen. However, the brightness is not the higher the better. If it is too high, it will have the opposite effect. Light pollution has become a hot topic nowadays, and high brightness will have an impact on the environment and people. Full color LED display screen: The LED panel and LED light-emitting tube undergo special processing to reduce the reflectivity of the LED panel and improve the contrast of the full-color LED display screen.
2、 Improve the grayscale level of full-color small pitch LED display screens
Grayscale level refers to the brightness level that can be distinguished from dark to bright in a single primary color of a full-color LED display screen. The higher the grayscale level of a full-color LED display screen, the richer and more vibrant the colors; On the contrary, the display color is single and the changes are simple. The increase in grayscale can greatly enhance color depth, resulting in a geometric increase in the display hierarchy of image colors. The grayscale control level of LED is 14bit~16bit, which enables high-end display products to achieve world leading levels in image hierarchy resolution details and display effects. With the development of hardware technology, LED grayscale levels will continue to evolve towards higher control accuracy.
3、 Reduce the dot pitch of full-color small pitch LED display screens
Reducing the dot pitch of a full-color LED display screen can greatly improve its clarity. The smaller the dot pitch of a full-color LED display screen, the more delicate its image display. At present, the concept of “micro spacing” has emerged in the industry, which refers to a display screen with a dot spacing specification of P2.0 or less and a lamp bead diameter not exceeding 1 millimeter. This requires mature technology as the core support, with relatively high investment costs and high prices for the resulting full-color LED displays. Fortunately, the market is now developing towards small pitch LED displays.
