As the main carrier of information broadcast and advertising, full-color LED Display is more and more following the trend of the times in contemporary times. High-definition video can often give people a more shocking visual experience, and the displayed content will be more realistic. To achieve high-definition display, there must be two factors, one is that the source requires full high-definition, and the other is that the display must support full high-definition. The full-color LED Display is also moving towards a higher definition display. So, how to improve the clarity of the full-color LED Display? Let’s have a rough analysis below.
First of all, improve the contrast of full-color LED Display. Contrast is one of the key factors that affect the visual effect. Generally speaking, the higher the contrast, the clearer and more eye-catching 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 full-color 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.
In fact, the contrast improvement of full-color LED Display is mainly to increase the brightness of full-color LED Display and reduce the reflectivity of the screen surface. However, the brightness is not as high as possible, too high, but it will be counterproductive. Light pollution has become the current heat. The topic of discussion, too high brightness will affect the environment and people. Full-color LED Display LED panels and LED light-emitting tubes undergo special processing, which can reduce the reflectivity of the LED panel and increase the contrast of the full-color LED Display.
Secondly, increase the gray level of the full-color LED Display. The gray level refers to the number of brightness levels that can be distinguished from the darkest to the brightest in the single primary color of the full-color LED Display. The gray level of the full-color LED Display The higher the value, the richer the color and the more gorgeous 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 control level is 14bit~16bit, which makes the image level resolution details and display effect of high-end display products reach the world advanced level. With the development of hardware technology, LED gray scale will continue to develop to higher control accuracy.
Finally, reducing the dot pitch of a full-color LED Display can improve its clarity. The smaller the dot pitch of a full-color LED Display, the more delicate the screen display. However, mature technology must be used as the core support for this. The input cost is relatively high, and the price of the full-color LED Display produced is also high. Fortunately, the market is now moving towards small-pitch LED Display.
