Ahora cada vez más siguen la tendencia de los tiempos. El vídeo de alta-definición a menudo puede brindar a las personas una experiencia visual más impactante, y el contenido que se muestra hace que las personas se sientan más reales. Para lograr una visualización de alta -definición, debe haber dos factores, uno es que la fuente de la película requiere Full HD y el otro es que la pantalla debe ser compatible. De hecho, la pantalla LED también está logrando un gran avance en la visualización de -definición más alta, entonces, ¿cómo mejorar su claridad? El siguiente editor de pantalla LED de Sichuan se compartirá con usted, espero que le sea útil.
1. Increase the contrast of the LED display
Contrast is one of the reasons that affects the visual effect. Contrast is the contrast of colors. The contrast between black and a hundred is dark and bright. Generally speaking, the higher the contrast, the clearer and more eye-catching the image, and the brighter and brighter the color. High contrast is very helpful for image clarity, detail performance, and grayscale performance. In some text and video displays with large black and white contrast, the high-contrast full-color LED display has advantages in black and white contrast, sharpness, and integrity. Contrast has a greater impact on the display effect of dynamic video. Because the light and dark transition in dynamic images is 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 LED display is mainly to improve the brightness of the LED display and reduce the surface reflectivity of the screen. However, the brightness is not as high as possible, too high, but it will be counterproductive, and light pollution has become a hot topic now. Excessive brightness will affect the environment and people. LED display LED panel and LED light-emitting tube are treated with special process, which can reduce the reflectivity of LED panel and improve the contrast ratio of LED display.
2. Improve the gray level of full-color LED display
The gray level refers to the brightness level that can be distinguished from the darkest to the brightest in the brightness of the single primary color of the LED display. , the change is simple. The improvement of the gray level can greatly improve the color depth, so that the display level of the image color increases geometrically. The LED grayscale control level is 14bit16bit, 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, LED gray scale will continue to develop to higher control precision.
3. Reduce the dot pitch of the LED display
Reducing the dot pitch of the LED display can greatly improve its clarity. The smaller the dot pitch of the LED display, the finer the screen display. However, this is something that everyone can take into account. It is difficult to implement and the input cost is relatively large. Fortunately, the market is now developing towards small-pitch LED displays.
