Abstract

A tintable window is described having a tintable coating, e.g., an electrochromic device coating, for regulating light transmitted through the window. In some embodiments, the window has a transparent display in the window's viewable region. Transparent displays may be substantially transparent when not in use, or when the window is viewed in a direction facing away from the transparent display. Windows may have sensors for receiving user commands and/or for monitoring environmental conditions. Transparent displays can display graphical user interfaces to, e.g., control window functions. Windows, as described herein, offer an alternative display to conventional projectors, TVs, and monitors. Windows may also be configured to receive, transmit, or block wireless communications from passing through the window. A window control system may share computational resources between controllers (e.g., at different windows). In some cases, the computational resources of the window control system are utilized by other building systems and devices.

First claim

What is claimed is:

1. A window assembly, comprising:
a first substrate;
a second substrate;
an optically switchable device deposited on the first substrate; and
a transparent display on the second substrate, wherein:
the optically switchable device (OSD) is configured to switch between a first state and a second state, the first state being a tinted state and the second state being a clear state;
the transparent display is configured to switch between a third state and a fourth state, the third state being emissive of light, the fourth state transmissive of light;
the optically switchable device reduces light transmission before reaching the transparent display; and
the assembly is configured to switch between a fifth state and a sixth state, the fifth state and the sixth state resulting from the OSD being tinted to respective, different, tint states intermediate to the first state and the second state.

2. The assembly of claim 1 , wherein:
the fifth state is opaque, and
the sixth state is transparent.

3. The assembly of claim 1 , wherein the optically switchable device is an electrochromic device.

4. The assembly of claim 3 , wherein the electrochromic device comprises:
a first transparent conductive layer,
a second transparent conductive layer,
an electrochromic layer disposed between the first transparent conductive layer and the second transparent conductive layer, and
an ion conducting layer disposed between the first transparent conductive layer and the second transparent conductive layer.

5. The assembly of claim 3 , wherein the transparent display comprises a transparent light emitting diode.

6. The assembly of claim 5 , wherein the transparent light emitting diode is an organic light emitting diode.

7. The assembly of claim 3 , further comprising a spacer between the first substrate and the second substrate.

8. The assembly of claim 3 , further comprising an electrically insulating layer between the optically switchable device and the transparent display.
