Individual areas of the screen can be magnified many times using an electronic magnifier.

A lamp is located inside the equipment body, which acts as a source of light flux. The beam passes through this system and is divided into three primary colors, after which a pixel structure is created in the modulator. The control unit receives a signal, regulates the direction of operation of the matrix. After that, the lens needs to collect streams of different colors, due to which the image is formed on the screen. The lens performs the task of scaling the picture.
