Core technology processing of led electronic display

Many people may not know that LED electronic displays have accumulated a variety of color processing technologies over time, from the initial monochrome display, two-color display, and three-primary color display to today’s colorful and diverse LED displays. Become one of the core technologies of touch display. 1. Color reduction processing. The birth of blue and green LEDs makes full-color LED electronic displays favored by users due to their wide color gamut and high brightness. When people’s skin color is usually displayed, they will be visually received. Wrong deviation, as a result, color reproduction processing technology has also emerged as the times require. 2. White field color coordinate adjustment. White field color coordinate adjustment is one of the most basic technologies for full-color LED electronic displays. Many LED electronic display manufacturers have begun to standardize the color matching process of full-color screens. However, some manufacturers often sacrifice some The gray levels of these primary colors are used to adjust the 100-field color coordinates, so that the overall performance cannot be improved. 3. The choice of primary color wavelength. LED electronic display screens have been widely used in various fields due to their own characteristics. The primary color wavelengths of LEDs required by different fields are also different. So how to choose LED primary color wavelengths to achieve better The visual effect is determined according to the use situation and occasion.　　 In addition, the so-called static screen in the design of the LED advertising screen corresponds to the dynamic screen. The static screen means that all the lights are on at the same time when the display screen is displayed. 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 short period of time.　　 There are many people who don’t know that the LED electronic display uses the duty cycle to drive one of its display functions, so its actual brightness has a great relationship with the lighting time period. When the brightness of the luminous tube is the same, the brightness of the static screen is much higher than that of the dynamic screen. Therefore, the general outdoor screen uses the static screen, and the indoor screen uses the dynamic screen to save the driving cost. One of the truths I told my friends here today is that one of its functional display characteristics must be taken into consideration.
