The LED transparent display has now become the main carrier of information broadcasting and advertising, and its high-definition display effect is its most favorite place. To have a high-definition display effect, there are two aspects: the source is high-definition and the display is high-definition. LED displays are also pursuing more high-definition display effects, such as small-pitch transparent LED displays. When it comes to high-definition display, the definition must be improved. How can the LED transparent display improve the definition?
1. Improve contrast
Contrast is one of the key factors affecting visual effects. In general, the higher the contrast, the clearer the image and the more vivid 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 LED transparent displays have excellent performance in black-and-white contrast, clarity, and integrity. In dynamic video, the performance of contrast is better. In dynamic video, the light-dark transition is faster. The higher the contrast, the easier it is for human eyes to distinguish such a conversion process. In addition, the special processing of the LED transparent display panel and the light-emitting tube can also increase the contrast of the LED transparent display and reduce the reflectivity of the LED panel.
2. Improve the gray level
The gray level refers to the brightness level that can be distinguished from the darkest to the brightest in the single primary color brightness of the LED transparent display screen. The higher the gray level of the LED transparent display screen, the richer the color and the brighter the color; on the contrary, the display color is single and the change is simple. The increase in gray level can greatly increase the color depth, and the display level of the image color is increased geometrically, the display level increases, the recognition degree increases, and the definition increases.
3. Reduce the Pixel Pitch
The smaller the dot pitch of the LED transparent display screen, the more pixels per unit area, the more delicate the picture that can be presented, and the higher the definition. Reducing the dot pitch is also the direction that most LED companies continue to work hard on. Today’s small-pitch LED displays are the best proof. However, this must have mature technology as the core support. The input cost is relatively high, and the price of the products produced is relatively high. In this regard, there is still a long way to go.
