Display and electronic apparatus
First Claim
1. A display comprising:
- at least one display cell having a display circuit;
a light emitting section operative to radiate light toward a front side of the display;
a first polarizing plate disposed above the light emitting section toward the front side of the display, and disposed in regions in which said display cell and a light receiving cell are formed, the light receiving cell including a light receiving element formed above the first polarizing plate;
a second polarizing plate formed above the light receiving cell;
a first transparent substrate disposed above the second polarizing plate toward the front side of the display, and disposed in either of an emitting optical path of said light emitting section and a reflecting optical path toward said light receiving cell; and
a second transparent substrate disposed above first transparent substrate toward the front side of the display,wherein the first polarization plate, the second polarization plate, and the first transparent substrate are configured such that light radiated outward from the light emitting section through the first polarization plate, the second polarization plate, and the first transparent substrate, and then reflected back toward the light emitting section by either an upper or lower surface of the second transparent substrate is absorbed by the second polarization plate after being transmitted again through the first transparent substrate.

Abstract
A display is provided. The display includes at least one display cell having a display circuit; at least one light receiving cell including a light receiving element; a light emitting section operative to radiate light to the side of a display surface; and a polarizing plate disposed on the front side in the display relative to a region in which the light emitting section is disposed and regions in which the display cell and the light receiving cell are formed, wherein a phase difference plate is disposed at a position which is on the front side relative to the light receiving cell and in either of an emitting optical path of the light emitting section and a reflecting optical path toward the light receiving cell.

10. A display comprising:
-
at least one display cell having a display circuit; at least one light receiving cell including a light receiving element; a back light operative to illuminate a front side of the display at a predetermined luminance; a first polarizing plate disposed above the back light toward the front side of the display; a first transparent substrate provided with said display cell and said light receiving element, and provided above the first polarizing plate; a second transparent substrate disposed opposite to said first transparent substrate; a liquid crystal layer disposed between said first transparent substrate and said second transparent substrate; a second polarizing plate formed above the second transparent substrate; a third transparent substrate disposed above the second polarizing plate, and disposed in either of an emitting optical path of said back light and a reflecting optical path toward said light receiving cell; and a fourth transparent substrate disposed above the third transparent substrate toward the front side of the display. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. An electronic apparatus comprising:
-
a processor; and a display operable with the processor, the display including; at least one display cell having a display circuit; at least one light receiving cell including a light receiving element; a back light operative to illuminate a front side of the display at a predetermined luminance; a first polarizing plate disposed above the back light toward the front side of the display; a first transparent substrate provided with said display cell and said light receiving element, and provided above the first polarizing plate; a second transparent substrate disposed opposite to said first transparent substrate; a liquid crystal layer disposed between said first transparent substrate and said second transparent substrate; a second polarizing plate formed above the second transparent substrate; a third transparent substrate disposed above the second polarizing plate, and disposed in either of an emitting optical path of said back light and a reflecting optical path toward said light receiving cell; and a fourth transparent substrate disposed above the third transparent substrate toward the front side of the display. - View Dependent Claims (19)
