High-end Large Venue Laser Projector DM730ST for Engineering Projects

DM730ST adopts the DLP technology with the 0.70”DMD chip. DM730ST has the 7300 lumens brightness and the XGA (1024*768) ultra-high resolution, and this feature makes it can meet the projection of most of the highlighting environment.

DM730ST has the functions of built-in edge blending, 17*17 geometric correction and others, which is suitable for the immersive restaurant, interactive exhibition hall, multimedia classroom and other large venues.

Functions of Laser Projectors

Parameter

DLP Projection Technology

DM730ST 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

DHN geometric laser projectorsfocus on the development and the innovation of the laser light projectors. Comparing with the traditional light source, laser light source has the better unipolarity and the directional. Laser projectors also have the advantages of long service life, 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

DM730ST has the 7300 lumens brightness and the XGA (1024*768) ultra-high resolution, and this feature makes it can meet the projection of most of the highlighting environment.

Rich Colorful Performance

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 is that it can increase the visual perception and reduce the visual fatigue. Viewers can enjoy the brightness and large screen.

Geometric Correction

DM730ST 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 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 projector when they adjust the multiple projectors. 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

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 projectors more convenient.

4500 Lumens 1920x1080 Ultra Short Throw ProjectorDM907

4500 lumens, 1920*1080 native resolution, 0.25 ultra short throw laser projector

DM907 has 4500 ANSI lumens with 1920*1080 native resolution, and it also has the built-in edge blending function. The function of 17*17 geometric correction can change the image into any different shapes. The 0.25 ultra short throw can reduce the distance between the projector and the screen. DM907 has a touch control function, which makes it more suitable for the interactive classroom.
