The display effect of LED display depends on many factors, such as brightness, point spacing, screen smoothness, attenuation and failure rate of lamp beads, usage environment and so on. So, what are the specific criteria? Let’s take a look at them.
I. Flatness and Reflectivity of Screen Surface
Local protrusion or concavity of LED display will lead to dead angle of viewing angle of display screen. Surface smoothness should be within (+1 mm) to ensure that the display image does not distort. Through special processing of panel and LED light emitting tube, LED display screen can reduce the reflectivity of LED display panel while ensuring the surface smoothness of the screen, and also improve the contrast of display screen (contrast). The higher the degree, the easier it is for human eyes to distinguish the light and shade conversion process in dynamic images.
Gray level refers to the series of brightness that can be distinguished from the darkest to the brightest in the monochrome brightness of full-color LED display screen. The higher the gray level, the richer the color, and the brighter the color. Conversely, the display color is single and the change is simple. The improvement of gray level can greatly enhance the depth of color and increase the number of geometric layers of image color display. LED display screen, using high-quality LED lights, gray level up to 16384, low brightness and high gray, the picture is clearer and brighter, the quality of the painting is more delicate.
3. Point spacing
The effect of point spacing on clarity is very obvious. The smaller the point spacing is, the more delicate the picture is displayed. The reduction of point spacing must be supported by mature technology. From the current trend, the reduction of point spacing is the inevitable choice of the market. However, relatively speaking, the smaller the spacing between points, the higher the cost of investment and the higher the price.
Warm reminder: Users should choose regular manufacturers of LED display when choosing LED display products. In this way, no matter in the quality, price or after-sales service of LED display, it will be safer and more assured!
