there are many factors that affect the display effect of led display screen, such as brightness, spacing between dots, smoothness of led screen surface, attenuation and failure rate of lamp beads, use environment and so on. next, we will explain in detail the factors that affect the display effect of the led display screen.
i. pixel spacing
pixel spacing has a very obvious effect on clarity. the smaller the pixel spacing is, the more delicate the display is. the reduction of pixel spacing must be supported by mature technology. from the current trend, the reduction of pixel spacing is the inevitable choice of the market. however, relatively speaking, the smaller the pixel spacing, the higher the cost of input and the higher the price.
2. flatness and reflectivity of screen surface
local protrusion or concave of p3.91 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. orida led display screen, through special processing of panel and led light emitting tube, can ensure the surface smoothness of the screen and reduce the reflectivity of the led panel at the same time. it can also improve the contrast of the display screen (the higher the contrast, the easier it is for the human eye to distinguish the light and shade conversion process in the dynamic image).
3. gray level of led display screen
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. oreda cob small spacing led display uses high quality led lights, low brightness and high gray, the picture is clearer and brighter, and the quality of the picture is more delicate.
