The at least one processor is set to display a first execution screen of at least one application on a first display area of the at least one display when the at least one housing is in a first state, wherein the first display area corresponds to the first state, identify the transition of the at least one housing from the first state to a second state, display a first screen, which includes at least one graphic object, on the second display area when a first condition is satisfied, wherein the first screen is displayed on the basis of the transition of the at least one housing from the first state to the second state, and display a second execution screen of a first application on at least a portion of the second display region in response to a first input to a first graphic object, corresponding to the first application, among the one or more graphic objects.

A head mounted display device includes: a mounting state sensor (for example, a sensor) in which a sensor value changes according to a mounting state; a mounting state determination unit for determining a mounting state according to an output of the mounting state sensor; a storage unit for storing a content to be displayed; a content control unit for changing the content stored in the storage unit; and a display unit for displaying the content stored in the storage unit. The content control unit changes the content according to the mounting state output by the mounting state determination unit.

A meeting control method includes: displaying one or more meeting presentation portals in a shared content selection page of a meeting application; determining, in response to a trigger operation on the one or more meeting presentation portals, a meeting presentation portal triggered by the trigger operation as a target meeting presentation portal, and determining an application corresponding to the target meeting presentation portal as a target application; and sharing and projecting, in the meeting application, only a target interface content in the target application based on protocol parameters of the meeting application and the target application in response to receipt success information transmitted by the target application, the target interface content being content that the meeting application has a permission of sharing and projection.

A video processing method for a circular panoramic video recording including an original field of view region at a first resolution and a further peripheral region outside the original field of view at a second, lower resolution, the method including the steps of performing spatial upscaling of the further peripheral region to a resolution higher than the second resolution.

Systems and techniques are described for providing a virtual interface for an XR device using a display interface device. A display interface device can display a landmark pattern, such as a quick response (QR) code, on its display. The display can be in the field of view of a camera of the XR device, so that camera captures images depicting the displayed landmark pattern. The XR device can generate, and display on its own display, output images based on the captured images, for instance by overlaying a virtual interface over the landmark pattern. The pose and/or size of the virtual interface in the output images can be based on the pose and/or size of the landmark pattern and/or display in the captured images. The display interface device can receive inputs through its display interface, such as touch-based inputs, which the display interface device can identify for the XR device.

A method provided by the present application comprises: obtaining a number n of rows of pixel units to be precharged; controlling a scanning driving chip to sequentially output n first scanning enable signals to a scanning driving circuit according to the number n of rows; and outputting a second scanning enable signal to the scanning driving circuit, so that the scanning driving circuit is controlled to output a second scanning signal to the pixel units of the n-th row to charge the pixel units of the n-th row.

A studio display environment and/or applications thereof are provided, wherein a display (e.g. LED display) is used onto which images or video are being shown, that are recorded by one or more cameras. The invention further relates to methods and systems for improved camera view in such studio display environment and/or applications.

A system includes a display panel with several pixels. A pixel includes a first, a second, and a third set of light emitting diodes (LED). Each LED in the first set outputs a first color light, each LED in the second set outputs second color light, and each LED in the third set outputs a third color light. The pixel emits a display light of a color that is a combination of the first, second, and third colors. In response to a driver inputting a first electric current to the first set of LEDs, a second electric current to the second set, and a third electric current to the third set, the display light from the pixel is of a predetermined target color, the first, the second, and the third electric current being substantially same and within a predetermined tolerance of each other.
