The necessary conditions for LED advertising screens to achieve high definition. LED advertising screens must meet these aspects in order to achieve high-definition images. First, the content played by the LED advertising screen, that is, the video source must be high-definition. Secondly, the ratio of the height to the width of the LED screen must be It should be fully coordinated with the video source, otherwise the proportion of the displayed screen will be out of balance. Finally, a dedicated video processor or video splicer is needed to complete high-definition image optimization and rebroadcasting. With the continuous progress and innovation of the society, LED advertising screens can be seen everywhere. As the main carrier of information broadcasting and advertising, in contemporary society, it is more and more following the trend of the times. High-definition video can often bring people a more shocking visual experience, and the content displayed will be more real.
So how to make the LED advertising screen more high-definition, the LED advertising screen manufacturer and Huiye Technology will analyze it for you. 1. LED advertising screen and video processor combined with LED video processor can use advanced algorithms to modify the signal with poor image quality, perform a series of processing such as deinterlacing, edge sharpening, motion compensation, etc., to enhance the details of the image, Improve picture quality. The video processor image scaling algorithm is used to ensure that the video image is scaled and processed to maintain the clarity and gray level of the image to the greatest extent.
In addition, the video processor is also required to have rich image adjustment options and adjustment effects, and to process image brightness, contrast, and grayscale to ensure that the screen outputs soft and clear images. 2. Improve the gray level of the full-color LED advertising screen. Higher, the richer the color, the brighter the color; on the contrary, the display color is single and 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. 3. Reduce the dot spacing of full-color LED advertising screens Narrowing the dot spacing of full-color LED advertising screens can improve its clarity very well. The smaller the dot spacing of full-color LED advertising screens, the more delicate the picture display will be.
However, for this point, there must be mature technology as the core support, and its input cost is relatively high, and the price of the produced full-color LED advertising screen is also high, but fortunately, the market is now developing towards small-pitch LED advertising screens. 4. Improve the contrast of full-color LED advertising screen Contrast is one of the key factors affecting 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 full-color LED advertising screens 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. In fact, the improvement of the contrast of the full-color LED advertising screen is mainly to increase the brightness of the full-color LED advertising screen and reduce the surface reflectivity of the screen body. However, the brightness is not as high as possible. The life of the screen will also cause light pollution.
Light pollution has become a hot topic now. Excessive brightness will have an impact on the environment and people. Full-color LED advertising screen The LED panel and LED light-emitting tube undergo special processing, which can reduce the reflectivity of the LED panel and improve the contrast of the full-color LED advertising screen. .
