7800 Lumens 1920x1200 0.65-4.7 Throw Ratio Laser Projector DU7800

7800 lumens, 1920*1080 resolution, 0.65-4.7 throw ratio laser projector

DU7800 is the professional laser projector. It has 7800 lumens brightness with WUXGA resolution, and five removable lens with 0.65-4.7 throw ratio. DU7800 high resolution projectors supports vertical and horizontal 2*360°projection.
  • Functions of Laser Projectors
  • Parameter
DU7800 360 projector adopts the professional laser light source. The brightness attenuation of laser light source is slower. DU7800 has the 7800 lumens brightness, WUXGA resolution, 20000hours service life and support 3D mold. It has 5 alternative lens and the throw ratio covers most range from 0.65 to 4.7. It is equipped with DP, HDBaseT and other interfaces, which adopts superconducting pipe liquid cooling, and supports 7*24 hours uninterrupted operation and 720 degrees installation at any angle.

DU7800 360 VR projector is widely applied to cultural tourism, exhibitions, movie theater, large conference rooms, classrooms and others based on its advantages of high stability, outstanding quality, excellent picture function of consistency. The virtual projection technology has brought great immersive experience to gyms and recreational facilities.

More Professional Laser Light Source

  • The professional laser light source has 20000 hours service life
  • The high def projector can be turned on and off quickly
  • 3d hd video projector with brightness color stability system, so that the color brightness maintains the long-term stable output.
  • This 3d TV projector has liquid cooling laser light source system, and this reasonable heat dissipation design can make sure the stable output of the light source for a long time.

The Better Picture Quality

  • DU7800 uses a new laser light source, with the original high contrast DLP projection system, comprehensively improve the projector color performance.
  • Compared with the same level of laser engineering projectors, DU7800 has more profound black- level performance and brighter white field, which makes the picture contrast higher and the picture level richer. It can show more details when projecting the same image.

Higher Performance, More Convenient Framework Design

  • The stability of DMD chip can effectively avoid the color cast caused by chip aging.
  • The service life of 20,000 hours light source can effectively avoid the trouble of changing the light and readjusting, splicing and edge blending.
  • For users, it can reduce maintenance costs, maintenance time and the loss caused by the shutdown of maintenance time.
  • It is more suitable for long time use in cultural tourism, theme parks and other occasions.
  • The professional color matching design of DHN 360 projector makes it easy to solve the chromatic aberration problem in the application of edge blending.

Totally-enclosed Design

The laser light source module is designed with full seal
Optical -mechanical system is designed with full seal
DMD chip is designed with full seal
Optical lens designed with full seal
Dual color wheel designed with full seal
Liquid cooling system designed with full seal
Dust can't get into the laser optical system, so the equipment runs stably for a long time and the brightness and color output more stable.

Especially for Mosaic Fusion Design, Color Consistency is Higher

Excellent light path design can reduce the thermal drift of projection to minimum, which is more conducive to splicing and fusion.
The color matching function specially designed by DHN laser projector supplier for splicing and fusion enables the brightness and color consistent before adjusting. In the field of large-screen splicing and fusion, chromatic aberration problem can be easily solved. DHN offer vaarious types of 3d laser hologram projectors, find more to compare with.

Support Full Series 3D

The high DEF projector support blur-ray 3D DLP-link 360 video projection; support frame sequential format, frame encapsulation format, Top-under format, side by side format.
Five lenses are interchangeable and the projection ratio covers the vast majority of the range from 0.65 to 4.7
Lens disassembly and assembly is more convenient
Support lens electric focusing, electric displacement, electric zoom (if variable)

Safer Design

Equipped with laser safety lock, if the laser tv projector is switched on and the lens is removed or the lens is not installed correctly, the laser tv projector will automatically shut down;
The lens has a detachable design to prevent the lens from being easily removed.

HDBaseT Interface for Long Distance Transmission

Built-in HDBaseT receiver, which can support 100 meters long transmission of video and control signals, through super five or six types of network cable and HDBaseT transmitter, can support 100 meters long transmission of video and control signals.
