Also referring to Fig. 1, now head-up-display system provided by the invention is illustrated.Head-up-display system, including
Frame body (not shown), the glass 3 being arranged on frame body, and for that will have the image projection of predetermined color on glass 3
Projector 1；The optical filter 2 penetrated for predetermined color light is provided between projector 1 and glass 3, and optical filter 2 is located at throwing
Shadow device 1 goes out on light path；The reflectance coating 31 for the reflection of predetermined color light portion is covered on glass 3.
In this way, projector 1 generates the image of predetermined color, which is projected to after optical filter 2 on glass 3, the figure
The some light of picture is reflected by reflectance coating 31 so that eyes of user 4 is watched；Sunlight is after glass 3 if being irradiated to optical filter
On 2, other than the light of predetermined color can be by optical filter 2, other light by 2 absorption/reflection of optical filter, are avoided
Excessive sunray reaches at projector 1 by optical filter 2 and damages projector 1.
Optionally, in one embodiment, the light that projector 1 is emitted is by the anti-of at least two reflecting mirror (not shown)
It is connect again in this way, can easily adjust light by adjusting two reflecting mirrors with optical filter 2 by optical filter 2 after penetrating
The angle of touching and the position contacted with optical filter 2；In this way, when projector 1 light after reflecting mirror between optical filter 2
When angle is that sunlight is not easy the angle occurred, projection is reached after capable of largely avoiding sunlight from passing through optical filter 2
Device 1 simultaneously damages projector 1.
Further, referring to Fig. 1, a kind of specific embodiment as head-up-display system provided by the invention, throws
Shadow device 1 is the laser light source that can generate predetermined color laser beam.In this way, the light beam monochromaticjty that laser light source generates is good, lead to

One region includes the first block of muti-piece, and each first block is covered each by red filter film；Second area includes the second block of muti-piece,
Each second block is covered each by Yellow filter film；Third region includes muti-piece third block, and each third block is covered each by blue
Filter coating.Pass through in this way, the feux rouges being radiated on transparent substrates passes through the first different blocks respectively, is radiated on transparent substrates
Yellow light pass through the second different blocks respectively and pass through, be radiated at the blue light on transparent substrates respectively by different third blocks
Pass through；Photic-energy transfer is more uniform after the feux rouges that i.e. projector 1 generates passes through muti-piece red filter film；The Huang that projector 1 generates
Photic-energy transfer is more uniform after light passes through muti-piece Yellow filter film；The blue light that projector 1 generates passes through after muti-piece blue filter film
Photic-energy transfer is more uniform.
Optionally, in one embodiment, the first block of muti-piece is spaced apart from each other setting, and the first block of muti-piece is uniform
It is laid on transparent substrates；The second block of muti-piece is spaced apart from each other setting, and the second block of muti-piece is uniformly distributed in light transmission base
On plate；Muti-piece third block is spaced apart from each other setting, and muti-piece third block is uniformly distributed on transparent substrates.In this way, throwing
The feux rouges that shadow device 1 generates can be uniformly distributed after capable of passing through from different first areas, and the yellow light that projector 1 generates can be from
Different second areas can be uniformly distributed after passing through, after the blue light that projector 1 generates can be passed through from different third regions
It can be uniformly distributed.
Further, referring to Fig. 1, a kind of specific embodiment as head-up-display system provided by the invention, filter
Mating plate 2 is located on the outside of the light-emitting window of projector 1.In this way, the light that projector 1 comes out can pass through optical filter 2；Reduce external veiling glare
