Abstract
A flexible light emitting sheet is curved along a curved liquid crystal screen constituting a meter display, and comprises one of a single sheet of a flexible transparent resin with a system of monoxide silicon particles mixed therein, an electroluminescent substance relatively high of brightness, and a flexible transparent resin sheet and a set of light emitting diodes arranged thereon in a plane conforming manner.
Claims31
A liquid crystal display device comprising:
- a curved liquid crystal screen having a rearwardly arcuate display surface and a light receiving back side surface;
- a flexible light emitting sheet curved along the light receiving back side surface of the curved liquid crystal screen and substantially parallel to the rearwardly arcuate display surface so as to display a curved picture having uniform optical characteristics;
- and
- wherein the curved light emitting sheet comprises a single sheet of a flexible transparent resin having a first refractive index with a system of monoxide silicon particles mixed therein in a pattern configured for compensating for the degree of curvature of the curved light emitting sheet so as to uniformly distribute light passing through the curved light emitting sheet and the light receiving back side of the curved liquid crystal screen, each of the monoxide silicon particles having a second refractive index different from the first refractive index.
The liquid crystal display device of clam 1, wherein the rearwardly arcuate display surface faces a first direction, the light receiving back side faces a second direction, and the curved light emitting sheet comprises a rearwardly arcuate light emitting surface facing the light receiving back side.
A liquid crystal display device comprising:
- a curved liquid crystal screen having a rearwardly arcuate display surface, a light receiving back side surface, and at least one vehicle display indicator located on the rearwardly arcuate display surface;
- a flexible light emitting sheet curved along the light receiving back side surface of the curved liquid crystal screen and substantially parallel to the rearwardly arcuate display surface such that the at least one vehicle display indicator displays a curved picture having uniform optical characteristics;
- and
- wherein the curved light emitting sheet comprises a single sheet of a flexible transparent resin having a first refractive index with a system of monoxide silicon particles mixed therein in a pattern configured for compensating for the degree of curvature of the curve light emitting sheet so as to uniformly distribute light passing through the curved light emitting sheet and the light receiving back side of the curved liquid crystal screen, each of the monoxide silicon particles having a second refractive index different from the first refractive index.
A liquid crystal display device comprising:
- a curved liquid crystal screen having a rearwardly arcuate display surface and a light receiving back side surface;
- a flexible light emitting sheet curved along the light receiving back side surface of the curved liquid crystal screen and substantially parallel to the rearwardly arcuate display surface so as to display a curved picture having uniform optical characteristics;
- and
- wherein the curved light emitting sheet comprises a sheet of flexible transparent film containing a pattern of monoxide silicon particles configured for compensating for the degree of curvature of the curved light emitting sheet and uniformly distributing light passing through the curved light emitting sheet and the light receiving back side of the curved liquid crystal screen.
A liquid crystal display device comprising:
- an arcuate liquid crystal screen having an curved display surface, and a curved light receiving surface;
- an arcuate light emitting sheet having a curved light emitting surface extending substantially parallel to the curved light receiving surface of the liquid crystal screen, and a light incident surface for receiving light from a light source;
- and
- wherein the arcuate light emitting sheet comprises a transparent resin having a first refractive index, and a pattern of monoxide silicon particles having a second refractive index different from the first refractive index and arranged between the curved light emitting surface and the light incident surface of the arcuate light emitting sheet so as to evenly transmit light passing from the light incident surface to the curved light emitting surface and uniformly display light from the curved light emitting surface of the arcuate light emitting sheet.
