Multi-functional active matrix organic light-emitting diode display
First Claim
1. A method of sensing a touching of portions of the front surface of an active matrix OLED display, the method comprising:
- integrating the OLED display with a solar panel located behind said OLED display and producing an electrical output signal corresponding to light that passes through said OLED display, including light emitted by said OLED display and reflected from an object touching the front surface of said OLED display; and
detecting the location of said touching object from said electrical output signal produced by said solar panel.

Abstract
A multi-functional active matrix display comprises a transparent front sheet, a semi-transparent layer of light emissive devices adjacent the rear side of the front sheet and forming a matrix of display pixels, and a solar cell layer located behind the light emissive devices for converting both ambient light and internal light7 from the light emissive devices into electrical energy, the solar cell layer including an array of electrodes on the front surface of the solar cell layer for use in detecting the location of a change in the amount of light impinging on a portion of the front surface of the solar cell layer.

2. An active matrix display comprising:
-
a transparent front sheet, a semi-transparent layer of light emissive devices adjacent the rear side of said front sheet and forming a matrix of display pixels for displaying images for viewing through said front sheet, and a solar panel located behind said light emissive devices, said solar panel including an array of electrodes on at least one surface of said solar panel for generating output signals for use in detecting the location of a change in the amount of light impinging on a portion of the front surface of said solar panel due to an object in front of said front sheet reflecting light from said emissive devices back through said front sheet and said emissive devices to said solar panel. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9)
