One or more optical modulation device, such as DMD are incided respectively, on LCD chip, or LCOS chip.By optical modulation device
Three kinds of primary lights of RGB after modulation are spectrally put together to be output on screen by a projection lens again to be formed
Coloured image.Because the efficiency comparison of bluish violet color laser is high, heat endurance and long-term reliability are good.YAG：The fluorescent material of Ce materials
Luminous quantum efficiency it is high, heat endurance is good, so bluish violet color laser and YAG：Ce fluorescent material has combined to form one efficiently
The white light source of rate, high reliability, and high brightness.
However, YAG is being excited using bluish violet color laser：The fluorescent material of Ce materials is formed in the white light source of white light, due to
YYAG：The yellow spectrum intensity of the fluorescent material stimulated emission of Ce materials is to weaken in red color segment, so that this kind of white light light
There is white balance in source, i.e. white light equalization point deviates Planck blackbody curve, a kind of partially green white is presented.
In order to avoid white balance problem, prior art provides green color components superfluous in a kind of white light for filtering synthesis,
So that white balance point is returned on Planck blackbody curve, to solve the problems, such as white balance.But this method is due to having filtered green glow
Composition, so as to reduce the light extraction efficiency of the white light source.
Prior art provides another method for increasing red laser in yellow fluorescence to solve the white of white light source
Equilibrium problem, laser of the spectral region near 638nm or 650nm is supplemented such as in yellow fluorescence, to increase in closing light
Red color components, so as to solve the problems, such as white balance.
