1, the deployment of white field color coordinates. White field color coordinate deployment is one of the most basic technology of full-color LED electronic display, many LED electronic display manufacturers began to standardize the full color screen color process. However, there are still some manufacturers often sacrifice some The gray levels of these base colors are used to allocate the color coordinates of a hundred fields so that the overall performance cannot be improved.
2, the choice of primary color wavelength, LED electronic display with its own characteristics in various fields has been widely used, different areas of the required color of the LED's primary colors are not the same. How to choose the LED color wavelength to achieve better vision The effect is based on usage and circumstances.
3, color reproduction processing. The birth of pure blue, pure green LED, so that full-color LED electronic display with its wide color gamut, high brightness sought after by the industry, in the performance of human skin color, there is a clear visual deviation Therefore, color reproduction processing technology came into being.
The so-called static screen in the LED advertising screen design corresponds to the dynamic screen (scanning screen). The static screen means that all the lamp points are lit at the same time when the display screen is displayed. The scanning screen utilizes the visual persistence characteristics of the human eye to light up the respective rows of the LED electronic display screen in a short period of time.
LED electronic display is driven by the duty cycle, so the brightness of the display has a great relationship with the time period of lighting. In the case of the same brightness of the luminous tube, the static screen is higher in brightness than the dynamic screen, so the general outdoor screen with a static screen, indoor screen with a dynamic screen in order to save driving costs.
