Curved windscreen for motor vehicle, has outer and inner glass surfaces with wedge angle that is changed from lower edge upto upper edge of field of vision to compensate double images in each point on vertical center line of field of vision

摘要

#CMT# #/CMT# The windscreen (1) has an outer glass surface (3) and an inner glass surface (2) curved in an area of a head-up-display (HUD) field of vision in a vertical direction such that distance between the surfaces at an upper edge of a HUD vision window is larger than distance between the surfaces at a lower edge of the window. The surfaces in the vertical direction comprise a wedge angle, which changes continuously from a lower edge of a HUD field of vision upto an upper edge of the HUD field of vision to compensate double images in each point on a vertical center line of the HUD field of vision. #CMT#USE : #/CMT# Curved windscreen for a motor vehicle. #CMT#ADVANTAGE : #/CMT# The wedge angle changes continuously from the lower edge of the head-up-display field of vision upto the upper edge of the head-up-display field of vision to compensate double images in each point on the vertical center line of the HUD field of vision, thus achieving a superimposition of reflection images within the area of the HUD field of vision. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a simplified schematic representation of beam characteristic, which leads in case of a head-up-display to emergence of double images.
