According to one embodiment, a color changing display includes a housing, a cover cooperatively coupled to the housing, a light panel, and a color display panel. The light panel and the color display panel are positioned between the housing and the cover. The light panel and the colored display panel are each selectively activated to operate in at least one of: a reflective mode, a transmissive mode, and a transflective mode.

An electronic appliance is provided. The electronic appliance includes a communication interface, a memory storing at least one instruction, and a processor which is connected with the memory and the communication interface and controls the electronic apparatus. Here, the processor may, by executing the at least one instruction, based on an event for reading extended display identification data (EDID) stored in the memory at an external apparatus connected through the communication interface occurring, toggle a first signal related to the communication interface, and after the first signal is toggled, monitor a signal output from the external apparatus and identify whether the external apparatus failed to read the EDID information, and based on identifying that the external apparatus failed to read the EDID information, toggle a second signal related to the communication interface.

A light emitting device includes pixel circuits arranged to form rows and columns and each including a light emitting element, signal lines each extending in a column direction and configured to supply a pixel signal to the pixel circuits, row selection lines each extending in a row direction and configured to supply a row selection signal to the pixel circuits, and column selection lines each extending in the column direction and configured to supply a column selection signal to the pixel circuits. At least one of the pixel circuits includes a light emission control circuit configured to allow the light emitting element of a pixel circuit indicated by the row selection signal and the column selection signal to emit light in a brightness according to the pixel signal that is being supplied to the pixel circuit.

Controlling the illumination at an endpoint to a communication session by transmitting, over the communication session, the color of the light to be emitted by the display of the receiving endpoint. In a particular embodiment, a method includes, during a video communication session between a first endpoint operated by a first user and a second endpoint operated by a second user, transmitting first video, comprising a solid color image, from the first endpoint to the second endpoint over the video communication session, wherein the first video is prominently displayed at the second endpoint. At the first endpoint, the method provides receiving second video from the second endpoint. The second video is captured at the second endpoint while the first video is being displayed at the second endpoint. The method also includes displaying the second video to the first user.

A voltage monitoring device includes a voltage supply device configured to supply a second voltage generated from a first voltage to the electric component, a voltage supply control section configured to control the voltage supply device, a voltage level detection section configured to detect a voltage level related to the first voltage, and a voltage monitor section configured to monitor the first voltage, compare the voltage level with a first threshold in the voltage non-supply time, compare the voltage level with a second threshold that is lower than the first threshold in the voltage supply time, control the voltage supply device to continue supplying the second voltage when the voltage level is higher than the first threshold or the second threshold, and control the voltage supply device to stop supplying the second voltage when the voltage level is lower than the first threshold or the second threshold.

A display driver includes image processing circuitry and drive circuitry. The image processing circuitry is configured to receive a foveal image, a full frame image, and coordinate data that specifies a position of the foveal image in the full frame image. The image processing circuitry is further configured to render a resulting image based on the full frame image independently of the foveal image in response to detection of a data error within the coordinate data. The drive circuitry is configured to drive a display panel based on the resulting image.

Systems and methods for managing refresh rates of applications running on a display device are disclosed. A computing device is designed to monitor and slow/reduce refresh rates for some applications running on the display device, while also allowing other applications to run at a fast/increased refresh rate. Each application is associated with a target device (e.g., server). The computing device can regulate a continuous stream of data, allowing some applications to access the data, while limiting/preventing other applications from accessing the data. The applications with access to the data can run at the fast refresh rates, while the remaining applications update at the slow refresh rates. As a result, the applications running at the fast refresh rates allow a user viewing the display device to actively monitor the respective servers associated with the fast-running applications, while reducing network load based on the relatively slow-running applications.

A method for processing an input image having an initial gamut to a targeted image having a wider gamut for display on a wide-gamut display includes determining a set of color scaling factors based on different parameters including one or more user-related characteristics of a user and the available gamut of the wide-gamut display device, applying a gamut-mapping to the input image based on the available gamut to generate a gamut-mapped image and applying the set of color scaling factors to the gamut-mapped image to generate the targeted image. A user device having a wide-gamut display device also includes an image processing module configured for performing the method for processing the input image.

In certain embodiments, a change to a display resolution (or other display configuration) to be used at a physical device may be effectuated without the need to reboot a virtual device associated with the physical device. In some embodiments, a display resolution for a portion of a virtual device user interface of a virtual device is determined based on display configuration information corresponding to a first physical device (e.g., a display resolution of the first physical device). The portion of the virtual device user interface is configured based on the determined display resolution, and the configured portion is sent to the first physical device. In some embodiments, in response to obtaining second display configuration information from a second physical device, the portion of the virtual device user interface is resized (e.g., without rebooting the virtual device), and the resized portion is sent to the second physical device.

Techniques for changing the presentation of information on a user interface based on presence are described. In an example, a computer system determines, based on an image sensor associated with the system, a first presence of a first user relative to a computing device. The computer system also determines an identifier of the first user. The identifier is associated with operating the computing device. The operating comprises a presentation of the user interface by the computing device. The computer system also determines, based on the image sensor, a second presence of a second person relative to the computing device. The computer system causes an update to the user interface based on the second presence.
