DLP Projection Technology of Geometric Laser Projector

DM730ST 1024x768 projector adopts the DLP technology with the 0.70”DMD chip. DLP technology has the advantages in the high resolution and the high color stability. The contrast ratio of the DLP projector is about twice of the LCD projector, which makes the color performance higher in the bright rooms. Digital color reproduction makes sure the high image reducibility of the real materials.

Laser Light Source of Geometric Laser Projector

DHN geometric laser projectors focus on the development and the innovation of the short throw hd projector. Comparing with the traditional light source, laser light source has the better unipolarity and the directional. This is also a long life projector with advantages of long service life and low cost of the maintenance. In theory, the service life can reach to 20000hours, and laser light source also has the good qualities of wide gamut, rich color and high color saturation, which makes the images through the projection are real and colorful.

High Brightness and Resolution of Geometric Laser Projector

DM730ST geometric laser projector has the 7300 lumens brightness, and it's a 1024x768 projector with XGA ultra-high resolution, and this feature makes it can meet the projection of most of the highlighting environment.

Rich Colorful Performance of Geometric Laser Projector

The brightness uniformity of the DM730ST is 85%(Typical), and the color uniformity is Δu’v’≦0.02. The advantage of the brightness uniformity and the color uniformity of the DM730ST geometric laser projector is that it can increase the visual perception and reduce the visual fatigue. Viewers can enjoy the brightness and large screen.

Long Life Projector with Geometric Correction

DM730ST 1024x768 projector supports 2*2, 3*3, 5*5, 9*9, 17*17 gridding's geometric correction, so one geometric laser projector can projection on the irregular screens (for example curved screen). Users can make the multiple projection edge blending to meet the requirements of the curved, plane, and the immersive polyhedral projection by this geometric correction function.

Geometric laser projector's built-in edge blending function can also choose the different colors of the projector grid lines, the density of the grids. Users can adjust the sharpness of the images after geometric correction, and the system will store the settings of the geometric correction for calling of the next time.

Users can lock the single long life projector when they adjust the laser multimedia projector. The remote-control signal will lock into the geometric laser projector you want to adjust, and other projectors will not have the unnecessary distractions, which can greatly improve the efficiency of the adjustment.

Rich Interface of Long Life Projector

Rich interface can satisfy the requirements of video and audio input and output, power supply, network control (ultra-long-distance transmission), RS232 control, firmware update and so on. Users can use the long life projectors more convenient.
