Imagine one thing not only improve the brightness and quality of the projection, but also save energy and protect the environment. Its almost impossible, but our Light Doubler Technology can do it. High efficiency 3D projection technology HE3D (High Efficiency 3D), using LEONISs patented Light Doubler Technology and Automatic Image Calibration and Optimization Technology, can recover and reuse the light reflected in the optical path, reducing light loss to a minimum, without the need to consume more light energy to achieve double brightness, and the light efficiency can reach more than 34%, and its 3D projection brightness and uniformity meet the relevant DCI / SMPTE regulations. It makes the picture clearer, brighter, and more colorful, bringing a more comfortable viewing experience to the audience, and perfectly presenting the creators creative intentions.
