Color Processing Technology and Static Dynamic Design of LED Electronic Display
LED electronic display has accumulated a variety of color processing technologies from the initial single-color display, two-color display, three-primary display, and today’s multi-primary display, which has become one of the core technologies of LED display.
1. Allocation of white field color coordinates. The allocation of white field color coordinates is one of the most basic technologies for full-color LED electronic displays. Many indoor ultra slim LED display manufacturers have begun to standardize the color matching process of full-color screens. However, there are still some manufacturers who often sacrifice a certain color. The gray levels of these primary colors are used to adjust the color coordinates of 100 fields, so that the comprehensive performance cannot be improved.
2. Selection of primary color wavelength, LED electronic display screens have been widely used in various fields due to their own characteristics, and the primary color wavelengths of LEDs required in different fields are also different. How to choose LED primary color wavelengths to achieve better vision The effect depends on the usage and occasion.
3. Color restoration processing. The birth of pure blue and pure green LEDs makes full-color LED electronic displays sought after in the industry for their wide color gamut and high brightness. There are obvious visual deviations when expressing human skin color. , As a result, the color reproduction processing technology came into being.
The so-called static screen in the design of led advertising screen corresponds to the dynamic screen (scanning screen). Static screen means that when the display screen is displayed, all the lights are lit at the same time. The scanning screen uses the visual persistence characteristics of the human eye to light up each row of the LED electronic display screen in a very short period of time.
The LED electronic display screen is driven by the duty cycle, so the displayed brightness has a great relationship with the lighting time period. When the brightness of the light-emitting tube is the same, the brightness of the static screen is higher than that of the dynamic screen, so generally, the static screen is used for the outdoor screen, and the dynamic screen is used for the indoor screen to save the driving cost.
