ABSTRACT:
A novel HUD (Head-UP Display) design in which the image forming source producing flight and aiming symbolic information is based unlike conventional HUDs not on projecting CRT, but on two LCD matrices to reduce its size, weight and power consumption. The images produced on matrixes are projected by optical system on transparently-diffusive or diffusively-reflective screen which is positioned in focal plane of HUD's optical collimating head. To enhance HUD brightness and resolution the image forming source is carried out in two variants:image forming source containing two matrices in which each matrix is forming half of full image which is projected on corresponding half of the screen,image forming source containing two matrices which images are projected on full screen; the matrices are shifted between each other horizontally and vertically by half of pixel pace (pace is the distance between two luminous dots).
