PROJECTOR Russian patent published in 2010 - IPC G03B21/02 

FIELD: physics.

SUBSTANCE: projector comprises a set of video cubes and system of their interconnection. Every said video cube incorporates opto-electronic unit, projection screen comprising inner component with mutually aligned applied Fresnel lens and outer component with applied lenticular structure, as well as screen attachment system with opto-electronic unit. Crosswise sizes of said unit do not exceed those of the screen, while video cubes mutual attachment spring system makes screens edges touch each other. Note here that the component with applied Fresnel lens feature length and width smaller than those of the component with applied lenticular structure by L_lt-L_Fl=2h, where h=1,4·k_teLS·L_le, k_teLS is temperature expansion factor of the component with lenticular structure, where L_lt is appropriate size of the component with applied lenticular structure, L_Fl is appropriate size of the component with applied Fresnel lens.

EFFECT: higher-quality image.
