Abstract
Provided are a display system and a vehicle. The display system includes a display assembly, a main visual area and an eye box. The display assembly includes a display panel and a prism assembly, the prism assembly includes a plurality of prisms, and the prism assembly is located on a light-emitting side of the display panel. Along a first direction of the plane of the eye box, a width of the main visual area is W, and the width of an eye box is W0, where W0≤W≤1.5*W0. According to the present disclosure, the relationship between the width of the main visual area and the width of the eye box in the display system is designed to improve glasses-free 3D display effect.
Claims20
A display system, comprising:
- a display assembly, wherein the display assembly comprises a display panel and a prism assembly, the prism assembly is located on a light-emitting side of the display panel, and the prism assembly comprises a plurality of prisms;
- a main visual area;
- and
- an eye box,
- wherein in a first direction of a plane of the eye box, a width of the main visual area is W, and a width of the eye box is W0, where W0≤W≤1.5*W0.
A vehicle comprising a display system,
- wherein the display system comprises:
- a display assembly, wherein the display assembly comprises a display panel and a prism assembly, the prism assembly is located on a light-emitting side of the display panel, and the prism assembly comprises a plurality of prisms;
- a main visual area;
- and
- an eye box,
- wherein in a first direction of a plane of the eye box, a width of the main visual area is W, and a width of the eye box is W0, where W0≤W≤1.5*W0.
A method for measuring a width of a main visual area of a display system, wherein the display system comprises a display assembly and an eye box, wherein the display assembly comprises a display panel and a prism assembly, the prism assembly is located on a light-emitting side of the display panel, and the prism assembly comprises a plurality of prisms,
- the method comprises:
- measuring light intensities of a plurality of sites selected on the plane of the eye box under a plurality of different light angles V respectively, wherein one light angle V corresponds to a group of parallel light emitted by the display assembly in a first plane, and the first plane is perpendicular to an axial direction of one of the plurality of prisms;
- comparing the light intensities of each of the plurality of sites under a plurality of different light angles V, and recording a light angle V corresponding to a maximum light intensity as a greatest intensity angle Vm, wherein one site corresponds to one greatest intensity angle Vm;
- and
- determining the width of the main visual area based on the greatest intensity angles Vm respectively corresponding to the plurality of sites,
- wherein in a first direction of a plane of the eye box, a width of the main visual area is W, and a width of the eye box is W0, where W0≤W≤1.5*W0.
