When we use the LED display, we hope that the display will be more realistic and high-definition, so that the whole picture quality will look more beautiful, so how can we make the display more high-definition?
Here, the hola-LED display manufacturer summarizes four factors that make the LED display display more high-definition:
- first, the film source requires full HD;
- second, the display requires full HD support;
- third, the dot pitch of the LED display is reduced ;
- fourth,the combination of led display and video processor.
In addition, video processors require a wealth of image adjustment options and effects,
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 some text and video displays with high black-and-white contrast, high-contrast full-color LED displays have advantages in clarity and integrity.
However, the brightness is not as high as possible. It also causes light pollution.
Light pollution has become a hot topic now. Excessive brightness will have an impact on the environment and people. Full-color LED display 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 display.
- Improve the gray level of the LED full-color display. 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 gray control level is 14bit~16bit, enabling high-end display products to reach the world’s advanced level of image-level resolution details and display effects.
With the development of hardware technology, LED gray scale will continue to develop towards higher control precision.
- Reduce the dot pitch of the full-color LED display. Reducing the dot pitch of the full-color LED display can improve its clarity. The smaller the dot pitch of the full-color LED display, the more delicate the picture will be displayed. 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 full-color LED display produced is also high, but fortunately, the market is now developing towards small-pitch LED displays.
- LED full-color display screen and video processor combined with LED video processor can use advanced algorithms to modify signals with poor image quality, perform a series of processing such as deinterlacing, edge sharpening, motion compensation, etc., to enhance the image quality Details, improve picture quality.
The scaling algorithm of the video processor image is to ensure that the sharpness and gray level of the image can be maintained to the maximum extent when the video image is scaled.
In addition, video processors require a wealth of image adjustment options and effects,
and to process image brightness, contrast, and grayscale to ensure that the screen outputs soft and clear images.
