1. A transparent display panel, comprising:
- (a) an array of display pixels, wherein each display pixel of the array comprises;
a number of separately controllable organic light emitting diodes (OLEDs), each the OLEDs being constructed to emit visible light of a different respective one of three colors,a first of the OLEDs being stacked on a light emitting surface of the second of the OLEDs and the second of OLEDs being stacked on a light emitting surface of the third of the OLEDs so that;
light from the emitting surface of the third OLED passes through the second and first OLEDs, light from the emitting surface of the second OLED passes through the first OLED, and light emerging from an emitting surface of the first OLED includes light emitted by the first OLED as well as light emitted by the second and third OLEDs; and
(b) a transparent region adjacent the stacked OLEDs formed from a transparent material.

Abstract
The examples relate to various implementations of a software configurable luminaire and a transparent display device for use in such a luminaire. The luminaire is able to generate light sufficient to provide general illumination of a space in which the luminaire is installed and provide an image display. The general illumination is provided by additional light sources and/or improved display components of the transparent display device.

8. A transparent display panel, comprising:
-
(a) an array of display pixels, each display pixel of the array comprising three separately controllable organic light emitting diodes (OLEDs), each of the OLEDs being constructed to emit visible light of a different respective one of three colors; and (b) a transparent region of the panel in-between OLEDs of the array, at least one of the transparent regions being associated with the OLEDs in each display pixel in the array; wherein the display pixels are structured so that the transparent display panel exhibits an overall optical transmissivity with respect to at least the three colors of light of 50% or more. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)
