Fast wireless communicators are used to carry out functions in a stage lighting display environment. LED tiles can be equipped with fast Internet such as 5G, and each of a number of LED tiles in an array can define an address that represents a part of the array. The video processor can break up an image into different parts for each LED tile of the array and send those different parts to the array.

A computer-generated scene is generated as background for a live action set, for display on a panel of light emitting diodes (LEDs). Characteristics of light output by the LED panel are controlled such that the computer-generated scene rendered on the LED panel, when captured by a motion picture camera, has high fidelity to the original computer-generated scene. Consequently, the scene displayed on the screen more closely simulates the rendered scene from the viewpoint of the camera. Thus, a viewpoint captured by the camera appears more realistic and/or truer to the creative intent.

In a display control device, a first display control unit displays values of a plurality of molding conditions in a first display area, on the basis of layout information including a display size and a display position of the plurality of molding conditions. A data setting unit sets as molding data the values of the plurality of molding conditions that are displayed in the first display area. On the basis of the layout information, and in the same layout as that of the first display area, a second display control unit displays for inspection in a second display area the values of the plurality of molding conditions based on the molding data which are stored in a storage unit.

A display apparatus capable of correcting an image quality change caused by long-term use is provided. The display apparatus includes: a display panel; a communicator configured to communicate with a service apparatus; and a controller configured to control the communicator to transmit operation information including a total operating time of the display apparatus and an operating temperature of the display apparatus, to the service apparatus; receive an image parameter from the service apparatus through the communicator, and based on the received image parameter data; process image data; and transmit the processed image to the display panel. The image parameter may include at least one of a brightness level, a contrast, a sharpness level, and a color density of the display panel.

A personal computer provides a video signal to dual first and second displays, improvement comprising the second display remote from the computer receiving its video signal by telemetry instead of through video cable. A video signal transmitter connects to the computer through a transmitter cable plugged into a computer display port. The cable from the second display that would otherwise be plugged into the computer video port is instead connected to a video signal receiver. The signal is then transmitted from the computer by the connected transmitter to the receiver connected to the second display. In an alternative embodiment, telemetry between the second display and the computer is achieved through a remote access card, the technology of which is well known in the art. The second display may detachably mount to the back of the first display.

A tiled display device is provided. The tiled display device includes a first panel and a second panel adjacent to the first panel. The first panel includes a first pixel unit, a second pixel unit and a third pixel unit. The second panel includes a fourth pixel unit, a fifth pixel unit, a sixth pixel unit, a seventh pixel unit, an eighth pixel unit and a ninth pixel unit. The second pixel unit, the fifth pixel unit, and the eighth pixel unit are arranged in a column and have a first color. The first pixel unit, the sixth pixel unit, and the seventh pixel unit are arranged in a column and have a second color. The third pixel unit, the fourth pixel unit and the ninth pixel unit are arranged in a column and have a third color.

Provided is an electronic device in which a first body having a first display and a second body having a second display are selectively coupled and linked, the electronic device including at least one processor which is provided at the first body so as to control the first display and which controls the first display and the second display on the basis of coupling to the second body, wherein the at least one processor is configured to identify whether the second body is coupled and on the basis of the coupling to the second body, output one area of a keyboard interface corresponding to a keyboard on the first display and output another area of the keyboard interface on the second display.

An electronic billboard and a controlling method thereof are disclosed, wherein the electronic billboard includes plural displaying areas, a user interaction tracker and a data flow manager. Each one of the display areas correspondingly form a telecommunication connection with one of plural video delivery devices, and respectively displays the image data provided by the video delivery devices. The user interaction tracker is used to calculate the interaction indexes between at least one user and each one of the display area. The data flow manager regulates the flows of the image data respectively delivered to the display areas according to the interactive indexes.

A video play system, a video play device, and a video play method are provided. The video play system includes: a display module and a plurality of play modules electrically connected to the display module. The plurality of play modules individually decode and transcode a video source having first resolution to generate target video data, and simultaneously output the target video data generated themselves to the display module. The display module plays a video image having second resolution according to multiple channels of the target video data.

An electronic apparatus is disclosed. The electronic apparatus includes: a memory storing an input image, and a processor configured to: apply a filter to the input image to identify the input image as a plurality of areas, apply a first low-frequency filter to a first area among the plurality of areas, and apply a second low-frequency filter to a second area among the plurality of areas to perform downscaling, wherein a cut-off frequency of the second low-frequency filter is configured to be higher than a cut-off frequency of the first low-frequency filter.
