This article introduces the whole optical match scheme for led display screen, including dice K-factor control, LED packaging technics, white balance and the optical design of model cup (LED lens). It is the most advanced optical match theory in LED display sign field.
White Balance is the important technology for LED Video display, it means: R:G:B is 3:6:1. to achieve the best color uniformity!
According to the needs of our customers, summed up a set of their own method of calculation. Customers who need the brightness and display distance between two points,they can tell us ,we can serve our customers all-round way for the customer’s led screen to make a perfect light distribution program. To facilitate the following presentation, I will introduce a few terms and definitions of indoor led screen and outdoor led display.
White Balance: The deployment of three colors to a vision of a white process. Deployment can be divided into two elements: color and brightness.
1: Set the fixed conditions: temperature, voltage, use the power cord.
2: Set the color targets and range (tolerance), generally refers to target colors X, Y values.
3: for white brightness adjustment.
The total brightness of color mixture is equal to the composition of mixed colors of various colors of light known as the brightness of the aggregate sum of the law.
Color appearance of the same light, regardless of whether their spectral components, as in the color mix has the same effect, that is, those who are visually the same color are equivalent, and this law can be derived color instead of law.
