Into in a luminescence unit, shades of colour is reached by colour mixture, so as to be shown as various effects, can meet basic display will
Ask, just can not realize wider wide colour gamut, and to reach broader colour gamut or resolution ratio, it is necessary to provide more in original basis
Essential colour, and more Essential colour are reached, the increase for being single led its true qualities of lamp bead is the most directly required, original
On the basis of increase more Essential colour and when monoblock LED large-size screen monitors are assembled into, could could improve the colour gamut of whole screen, reach preferably
Display effect.
RGB three primary colors and hyperchromic rear effect analysis：
Polycrystalline (explanation：Following polycrystalline refers to more than internal three LED chips of same encapsulation) LED encapsulation technologies can be with thorough
The Red Green Blue adopted since existing LED colorful display screens are born is overthrown and has combined to show the display side of color in bottom
Formula, by the combination of multi-color LED package technology, realizes the wide colour gamut and High precision of high picture quality image, also helps
In energy resource consumption is greatly reduced.Polychrome technology enables the color that common three primary colors are difficult accurate description accurately to show.
So-called polysilicon technology, just refers to and one and many has been newly increased on the basis of the RGB three primary colors of conventional LED package technology
Individual chip.If the display screen that the lamp bead that polycrystalline LED encapsulation technologies are produced is assembled into and traditional three colors (RGB) display screen pair
Than, an independent chip is increased on the basis of former RGB, and in the lamp bead used by traditional display screen, they are then all
Only tri- kinds of color chips of RGB.

More wide colour gamut, and wider wide display resolution.Not only can using the display screen of the polycrystalline LED lamp bead technology production
More vivo reproduction yellow, gold etc. are of all kinds relies only on the color that traditional RGB trichromatic techniques are difficult to true reappearance, together
When other colors it is enhanced after, good castering action can also be played to the expressive force of each portion's color, and also can be by increasing
One redness, by way of virtual display, increases display resolution, so as to reach more preferable display effect.
For LED package, the practical significance of technology upgrading is exactly as simply simply adding a new face
The light emitting diode of color with accurate reproduction colors color, effect, and also can be stretched various so as to improve color representation power
The colour gamut of color, so that the overall colour gamut of electronic display becomes more wide.Such as yellow, blue-green and aubergine, it is
More bright picture is shown, the brightness for lifting whole light source is needed.From the point of view of by spectrum, there is yellow, these Neutral colour
Performance problem just can be resolved, and the addition of yellow can make colour gamut wider, and can produce more under same energy consumption
Plus bright-coloured bright picture color.
