A color gamut controlling device and a display device including the color gamut controlling device. The color gamut controlling device includes a light sensing unit, a first calculation unit, a second calculation unit, and a color gamut calculation unit. The light sensing unit measures a luminance of external light. The first calculation unit calculates adjusted tristimulus values for each of three primary colors based on the measured luminance. The second calculation unit calculates final tristimulus values for each of the three primary colors using the adjusted tristimulus values and target tristimulus values for each of the three primary colors. The color gamut calculation unit calculates a corrected color gamut from the final tristimulus values. The light sensing unit may further measure tristimulus values of the external light for each of the three primary colors.

A method, of reducing display device energy consumption, including: (a) determining lighting conditions ambient to a display device; (b) determining content that a user chooses to view on the display device; (c) calculating the user's perception of display quality using an image appearance model; and (d) adjusting, when the perceived display quality is higher than a target display quality, display device conditions so that the perceived display quality matches the target display quality so as to reduce energy consumption. An apparatus utilizing the method so as to reduce energy consumption while providing an aesthetically pleasing viewing experience to a user.

A display device includes a main body provided with a display module on which an image is displayed, a bending module located at a center of a rear surface of the main body, and a controller. The controller includes controlling the bending module to change a curvature of the display module to any one of a flat mode in which the display module is flat, a first bending mode in which the display module has a first curvature, and a second bending mode in which the display module has a second curvature. Here, the second curvature is a maximum curvature of the display module. The controller further includes switching the display module to any one of the flat mode, the first bending mode, and the second bending mode based on a distance to a remote controller.

Systems, methods, and non-transitory computer readable media containing instructions for selectively controlling display of virtual objects are provided. In one implementation, virtual objects may be virtually presented in an environment via a wearable extended reality appliance operable in a first and second display modes; in the first display mode, positions of the virtual objects are maintained in the environment regardless of detected movements of the wearable extended reality appliance, and in the second display mode, the virtual objects move in the environment in response to detected movements of the wearable extended reality appliance; movement of the wearable extended reality appliance may be detected; selection of the first or second display mode may be received; display signals configured to present the virtual objects in a manner consistent with the selected display mode may be outputted for presentation via the wearable extended reality appliance in response to the selected display mode.

An information provision device for a vehicle allows information to be provided to a user appropriately, and includes an onboard device having a first control means that operates a display unit, and an external device having a second control means that outputs information from outside the vehicle to the first control means. The display unit includes a first region in which vehicle-status information is displayed and a second region in which the information from outside the vehicle is displayed. The first control means can determine priorities for the vehicle-status information and the information from outside the vehicle. The first control means operates the display unit such that either the first region or the second region, which contains high-priority information, is larger than the other. If prescribed conditions occur, the first control means operates the display unit such that the region containing low-priority information is larger than the other.

An auto focus device comprises a focus panel and a focus controller. The focus panel comprises liquid crystal between a first light-transmissive conductive film and a second light-transmissive conductive film, and the focus controller is configured to apply a voltage between the two light-transmissive conductive films at the position of at least one pixel, so that the liquid crystal at the position will have an expected focal length. An auto focus method comprises: acquiring information on eyesight status of a user; acquiring information on posture of the user; calculating expected focal length of the liquid crystal between the two light-transmissive conductive films at the position of at least one pixel according to the acquired user information; selecting a voltage to be applied between the two light-transmissive conductive films at the position according to the expected focal length; and applying the voltage between the two light-transmissive conductive films at the position.

An electronic device and a method generate a first model and a second model when the images presented by the electronic device are viewed by a user located at a reference location. The electronic device obtains an image of the user captured by a camera of the electronic device when the user views the images presented by the electronic device. The electronic device generates a third model according to the image of the user. The electronic device adjusts the images presented by the electronic device when the third model does not match the first model.

Disclosed is a display unit provided with a display control printed circuit board with a circuit configured to generate a display signal for display by a display panel and a fixing metal plate for securing the display control printed circuit board. The display control printed circuit board is provided with identification information reading means for reading identification information of the display panel, a memory stored with set values for generating display signals corresponding to the sizes of a plurality of display panels, and a display controller configured to generate the display signals. The fixing metal plate comprises one or more members electrically connected to the display control printed circuit board and configured to transmit the identification information of the display unit to the display control printed circuit board. The identification information reading means reads a set value for the display panel from the memory, based on the identification information of the display panel derived from the one or more electrically connected members, and sets the set values in the display controller configured to generate the display signals.

A mobile device has a display, one or more processors, and first memory storing instructions for execution by the one or more processors. The mobile device is configured to dock in a headset to form a head-mounted display. A near-field-communication (NFC) channel is established with a tag in the headset, the tag including second memory that stores one or more configuration parameters for the headset. The one or more configuration parameters are received from the tag via the NFC channel.
