特徴とするプロジエクシヨンＴＶシステム。 Projection T reflects images from three projection tubes (red, blue, and green) with mirrors and projects them onto a screen.
In the V system, in front of the blue projection tube is a dichroic mirror facing the image plane that reflects only light with a wavelength of around 470 nanometers or less and transmits light with wavelengths longer than that. A projection TV system is characterized in that a dichroic mirror is installed in front of the screen, facing the image plane, and reflects only light with a wavelength around 545 nanometers, and transmits light with other wavelengths.
