Three factors that affect the clarity of full-color LED displays

With the rapid development of LED display screens, full-color LED display screens, as the main carrier of advertising and information broadcasting, are increasingly following the trend of the times in the contemporary era. High-definition video can often bring a more shocking visual experience, and the content displayed will be more realistic.

01 Contrast

Contrast is one of the key factors that affect the visual effect. Generally speaking, the higher the contrast, the clearer and more visible the image, and the brighter and more vivid 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, high-contrast full-color LED displays have 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 transitions are faster in dynamic images, the higher the contrast, the easier it is for human eyes to distinguish such a conversion process.

02 Dot Pitch

Dot Pitch: Reducing the dot pitch of a full-color LED display can improve its sharpness. The smaller the dot pitch of a full-color LED display, the finer the screen display.

However, this point must have mature technology as its core support. Its input cost is relatively large, and the price of the full-color LED display produced is also high. Fortunately, the market is now moving towards small-pitch LED displays.

03 gray level

The gray level refers to the number of brightness levels that can be distinguished from the darkest to the brightest in the single-primary brightness of a full-color LED display. The higher the gray level of a full-color LED display, the richer the color and the more beautiful the color; , Single display color, simple change.

Increasing the gray level can greatly increase the color depth, which makes the display level of the image color increase geometrically. The LED gray level control level is 14bit ~ 16bit, which makes the high-level display products' image level resolution details and display effects reach the world advanced level. With the development of hardware technology, LED gray levels will continue to develop to higher control accuracy.
