A light emitting substrate, a method of driving a light emitting substrate, and a display device are provided. The light emitting substrate includes a plurality of light emitting units arranged in an array. Each light emitting unit includes a driving circuit, a plurality of light emitting elements, and a driving voltage terminal. The plurality of light emitting elements are sequentially connected in series and connected between the driving voltage terminal and the output terminal of the driving circuit. The driving circuit is configured to output a relay signal through the output terminal in a first period according to a first input signal received by the first input terminal and a second input signal received by the second input terminal, and supply a driving signal to the plurality of light emitting elements sequentially connected in series through the output terminal in a second period.

The present teaching relates to method, system, medium, and implementations for LED display. A first signal is received that signals a timing for a next data transfer. In response to the first signal, a bit-based image block stored in a memory is transferred, via a bus connected thereto, to one of a pair of alternate buffers pointed to by a write buffer pointer, which is subsequently toggled to point to another of the pair of alternate buffers. A second signal is received that signals a timing for refreshing the LED display. In response to the second signal, the bit-based image block is retrieved from the one of the pair of alternate buffers pointed to by a read buffer pointer, which is then toggled to point to the other of the pair of alternate buffers. The lights of the LED display are then refreshed in accordance with control signals generated based on the bit-based image block.

The present invention relates to a display device and a method of controlling therefor. According to one embodiment of the present invention, a display device includes a memory configured to store at least one or more contents, at least one or more sensors, a network interface module configured to communicate with at least one or more lights, a display module configured to output the at least one or more contents stored in the memory, and a controller coupled with the memory, the sensor, the network interface module and the display module. In this case, the controller controls the display module to output specific content stored in the memory at specific timing and controls the network interface module to transmit a control signal to a specific light at the specific timing.

A client is provided which is connectable to multiple mobile units while reducing or eliminating inconvenience to be given to a user. A client 2 is a client 2 which is connectable to multiple mobile units 3 and 4, and includes: a client output unit 25 configured to output information; a client communication unit 23 configured to perform communication; and an output controller 211. When connection is made to one mobile unit of the mobile units 3 and 4 through the client communication unit 23, the output controller 211 outputs pieces of mobile unit identification image information P1 to P8, M1 and M2 which can identify the connected mobile unit, on the basis of communication with the connected mobile unit, to the client output unit 25.

An information processing apparatus includes a communication unit, a display, and a remote operation unit. The communication unit communicates with an external device. The display displays information, and receives an input operation. The remote operation unit remotely operates a screen displayed on the external device. The remote operation unit operates the external device in a state in which at least one operation on the external device are invalidated. In the case where a drawing input operation is performed on the display with the screen displayed on the external device displayed on the display, the remote operation unit validates an operation corresponding to the drawing input operation, among the at least one operation on the external device which have been invalidated.

A temperature control method is provided. In the method, a terminal determines a current temperature of the terminal and determines, based on a preset corresponding relationship between a screen display frame rate and a temperature interval, a target temperature interval of the current temperature of the terminal in the preset corresponding relationship. The terminal may determine a target screen display frame rate corresponding to the target temperature interval. And the terminal may adjust a current screen display frame rate of the terminal to the target screen display frame rate, to control the temperature of the terminal to be within a preset temperature range.

A method includes accessing image data and depth data corresponding to image frames to be displayed on an extended reality (XR) display device, and determining sets of feature points corresponding to the image frames based on a multi-layer sampling of the image data and the depth data. The method further includes generating a set of sparse feature points based on an integration of the sets of feature points. The set of sparse feature points are determined based on relative changes in depth data with respect to the sets of feature points. The method further includes generating a set of sparse depth points based on the set of sparse feature points and the depth data and sending the set of sparse depth points to the XR display device for reconstruction of a dense depth map corresponding to the image frames utilizing the set of sparse depth points.
