A color converter device includes an array of color conversion regions. The array of color conversion regions includes color conversion regions of a first type and color conversion regions of a second type that is distinct from the color conversion regions of the first type. A respective color conversion region of the array of color conversion regions includes a respective photonic crystal structure defining a respective two-dimensional pattern. The respective color conversion region includes a respective color conversion matrix. The color conversion regions of the first type converts light of a first color into light of a second color that is distinct from the first color and the color conversion regions of the second type converts the light of the first color into light of a third color that is distinct from the first color and the second color.

Described examples include a process that includes illuminating a spatial light modulator at a first illumination level during a first bit-plane and stopping illumination at a beginning of a second bit-plane subsequent to the first bit-plane. The process also includes resuming illumination after a settling period of the spatial light modulator at a second illumination level for a time period such that a total illumination energy during the second bit-plane is equivalent to an intended illumination energy for the second bit-plane at the first illumination level and stopping illumination at the second illumination level before a subsequent third bit-plane.

Various display control methods and apparatuses are provided. A method comprises changing a ratio of pixels distributed along two directions in each effective display region of at least one display unit of a display system, wherein light emitted by each pixel in the effective display region of each display unit in the at least one display unit is transmitted to a visual angle range by a lens corresponding to the display unit in the display system, and the two directions comprise a first direction and a second direction parallel with the display unit and orthogonal with each other; and displaying a content to be displayed by the changed display system. Differentiated display of visual angle information of two mutual orthogonal different directions can be thereby realized.

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.
