Abstract: A computing device executes a “night mode” for optimizing the device display's light emission for night-time use. The device stores a dimming filter and/or a color filter to achieve a desired brightness and color temperature of the display. The dimming filter is used to set a display backlight level and to “dim” the display data itself via alpha blending of the screen image with a grey mask. The computing device can blend the image with the grey mask in order to dim the display below system minimums. The color filter is alpha blended with each pixel in the image to reduce the luminance of blue light until the luminance is lower than that of another color of the emitted light. The proper dimming and color filters may be selected according to a desired screen brightness obtained from user input and/or from ambient light sensor data.

Abstract: Systems, methods, and computer-readable media are disclosed for mountable clear displays and projection systems. In one embodiment, a system may include a mirror surface and a transparent display sheet adhered to the mirror surface. The transparent display sheet may include a blue phosphor layer that absorbs light having the first wavelength and emits light having a fourth wavelength of about 460 nm, a green phosphor layer that absorbs light having the second wavelength and emits light having a fifth wavelength of about 530 nm, a red phosphor layer that absorbs light having the third wavelength and emits light having a sixth wavelength of about 625 nm, and a blue light blocking layer attached to the red phosphor layer of the transparent display sheet, the blue light blocking layer configured to absorb blue light passing through the transparent display sheet.

Abstract: The disclosure pertains to aligning an electronic display or light reflected from the electronic display relative to a position of a user (i.e., viewer), and thus enhancing an overall perceived brightness, contrast ratio, and viewing angle performance of an electronic display (e.g., a specular reflective display) irrespective of illumination conditions (e.g., sunlight, airplane lighting, and overhead lamps). In some embodiments, an electronic device may determine user position data for a position of a user with respect to the electronic display. For example, the electronic device may capture images of the user using one or more image sensors. The user position data may then be processed by the electronic device to generate signals which may modify display characteristics of the electronic display to align an electronic display or light reflected from the electronic display relative to the position of the user.
