Title:
REFLECTION MIRROR UNIT AND HEADS-UP DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/009081
Kind Code:
A1
Abstract:
This reflection mirror unit comprises: a curved plate-like resin molded base body (340) having a concave surface (345) that is wide in the long direction and extends in the short direction, a pair of pieces of double-sided tape (341) which is separated between positions on both sides of the concave surface (345) in the long direction and which is attached thereto, and a plate-like reflector that is attached to the entirety of the double-sided tape (341) and that has a curve following that of the concave surface (345). Where the predicted distortion rate Rp is defined as the predicted amount that the display optical image distorts due to deformation of the reflector, the tape width Wt is defined as the dimension in the long direction of each piece of the double-sided tape (341), and the tape position distance Δt is defined as the distance from the center point in the long direction of the base body (340) to the center point in the long direction of each piece of double-sided tape (341), the following are established: Rp=0.0933·Wt+2.1167≤5[%]; and Rp=0.1167·Δt-0.5697≤5[%].
