This abstract first appeared for US patent application 18198006 titled 'HEAD-UP DISPLAY AND DISPLAY DEVICE

Simplified Explanation

The patent application describes a head-up display technology.

  • The display includes a light source, a liquid crystal panel, and a prism sheet.
  • The liquid crystal panel transmits light from the light source and projects an image.
  • The prism sheet refracts the transmitted light.
  • The prism sheet has a sheet surface parallel to the liquid crystal panel and multiple prisms facing the panel.
  • The prisms are angular in shape and formed by two inclined surfaces.
  • The first prism surface is inclined with respect to the sheet surface.
  • The second prism surface is inclined with respect to the sheet surface and has a larger angle with the sheet surface than the first prism surface.
  • The angle between the first prism surface and the sheet surface is 35° or larger.


Original Abstract Submitted

A head-up display includes a light source, a liquid crystal panel configured to transmit light from the light source and project an image, and a prism sheet configured to refract the light transmitted through the liquid crystal panel. The prism sheet includes a sheet surface parallel to a plate surface of the liquid crystal panel, and a plurality of prisms facing the plate surface of the liquid crystal panel on a side opposite to the sheet surface and arranged in parallel, the prisms are each formed in an angular shape in cross-section by a first prism surface and a second prism surface, the first prism surface being inclined with respect to the sheet surface, the second prism surface being inclined with respect to the sheet surface and making a larger angle with the sheet surface than the first prism surface, and an angle between the first prism surface and the sheet surface is 35° or larger.
