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.

Thin-film devices, for example, multi-zone electrochromic windows, and methods of manufacturing are described. In certain cases, a multi-zone electrochromic window comprises a monolithic EC device on a transparent substrate and two or more tinting zones, wherein the tinting zones are configured for independent operation.

An at least partially self-powered photovoltaic sunshade and display system is provided, including a plurality of panels arranged in an array. Each of the plurality of panels has two sides, including a first side including a plurality of photovoltaic cells or a photovoltaic layer, and a second side having an array of light-emitting elements. The at least partially self-powered photovoltaic sunshade and display system includes energy storage means that receives charge from the plurality of panels and provides electrical power to the array of light-emitting elements. Each of the plurality of panels is rotatable about an axis such that the two sides are respectively rotatable towards or away from the sun, and towards or away from an exterior environment.

Resources of a system for controlling optically switchable windows may be used for a personal computing unit. The window system resources may include (i) a display associated with an optically switchable window, (ii) one or more processors of one or more controllers on a window network connected to a plurality of optically switchable windows in a building, wherein the one or more controllers are configured to vary tint states of the plurality of optically switchable windows in the building, (iii) memory of one or more controllers on the window network connected to the plurality of optically switchable windows in the building, and/or (iv) at least a part of the window network.

The present application discloses a transparent screen, including a first circuit board, an LED lamp bead and a plurality of first connecting columns. The first circuit board has a first surface and a second surface opposite to the first surface; the first circuit board includes a transparent portion provided with several first through holes and a mounting portion without through holes, and the LED lamp bead is mounted on the mounting portion of the first surface; and a first connecting column, mounted on the mounting portion of the second surface; where the first connecting column has a first limiting protrusion. The first connecting column is mounted on the mounting portion of the second surface which does not affect the transparency of the transparent screen.
