A wireless conferencing system for wirelessly connecting a computerized device with a display device includes at least a data transmitter. The data transmitter includes a transmitter self-powered unit, a data transmission module electrically powered by the transmitter self-powered unit, and a computer interface communicatively lined to the data transmission module, wherein when the computer interface is configured for detachably connecting to the computerized device, the data transmission module is powered and ready for wirelessly transmitting data from the computerized device to the display device without consuming power of the computerized device.

Provided is a display device including: an inputter/outputter comprising circuitry configured to request a content providing device to provide content at a first resolution and receive a first image at the first resolution from the content providing device, a display configured to display the first image, a memory storing one or more instructions, and a processor configured to execute the one or more instructions stored in the memory to: change a resolution requested to the content providing device from the first resolution to a second resolution, control the display to receive a second image from the content providing device and display the received second image in response to the change of the requested resolution, determine whether an error occurs in the displayed second image, and change the requested resolution from the second resolution to the first resolution based on an error occurring in the second image.

A method for optimizing a display image based on display content is provided. The method is applicable to a display control chip, and includes following operations: receiving a video signal configured to transmit an image of a frame; with respect to multiple different sub-areas in an area of the image, calculating a pixel number distribution of each sub-area along multiple characteristic values; determining, according to the pixel number distribution, whether the sub-area comprises a corresponding first target pattern of multiple first target patterns; if the multiple sub-areas comprise the multiple first target patterns, respectively, performing a first preset image processing to the image to generate a processed image; if the multiple sub-areas are free from comprising the multiple first target patterns, respectively, omitting the first preset image processing to the image; and generating a display signal according to the processed image or the image.

A graphics processing unit (GPU) of a processing system transmits pixel data for a frame to a display in a compressed burst, so that the pixel data is communicated at a rate that is higher than the rate at which the display scans out the pixel data to refresh the frame at a display panel. By transmitting pixel data for the frame in a compressed burst, the GPU shortens the time spent transmitting the pixel data and extends the time before the next frame of pixel data is to be transmitted. During the extended time before the next frame of pixel data is to be transmitted, the GPU saves power by placing portions of the processing system in a reduced power mode.

Technology for a display source controller is described. The display source controller can receive display pixel data from a display source. The display source controller can convert the display pixel data to display symbol data that includes a plurality of 32-bit double words (DWords). The display source controller can divide the display symbol data that includes the plurality of 32-bit DWords for a number of unidirectional serial data channels. The display source controller can process, for each unidirectional serial data channel, the display symbol data at a 32-bit DWord granularity level. The display source controller can send the display symbol data for each of the unidirectional serial data channels over a physical serial link to a display panel.

An electronic apparatus includes: a signal output circuit configured to connect with an external apparatus connected to a display apparatus, a processor configured to control the electronic apparatus to: obtain information about a first image format supported in the display apparatus from the external apparatus, output a content signal having the first image format to the external apparatus through the signal output circuit to the display apparatus based on identifying that the external apparatus supports an interface protocol capable of transmitting the content signal having the first image format, and output a content signal having a second image format different from the first image format to the external apparatus through the signal output circuit based on identifying that the external apparatus does not support the interface protocol.

Systems and methods are provided to enable users to interact with user terminals having a touch screen interface without requiring the user to physically contact a surface of the touch screen interface.

A display apparatus includes a display, an interface, and a processor configured to, based on a dongle in which an application is stored being connected to the interface, display the application stored in the dongle on the display based on information on the application received from the dongle, and based on receiving a user command for selecting the application displayed on the display, transmit a command for executing the selected application to the dongle through the interface, and based on receiving an execution screen of the application executed in the dongle through the interface according to the command, display the received execution screen on the display The processor is further configured to, based on receiving the user command, transmit, through the interface, a command for communicating with an electronic apparatus, so that the dongle is connected to the electronic apparatus.

The present technology is to enable a transmitter device to read appropriate device information (EDID) from a receiver device with a reduced burden on the user. A memory unit that stores first device information and second device information, and a communication unit that communicates with an external device are included. The control unit determines to cause the external device to read the second device information, on the basis of reception of a rewrite signal for the first device information from the external device. It is possible to cause the external device (a transmitter device) to read appropriate device information (EDID) from a receiver device (a reception device) with a reduced burden on the user, and thus, user-friendliness can be increased.

A display module includes a first substrate; a plurality of micro-pixel packages provided on an upper surface of the first substrate and including a plurality of pixels arranged in two dimensions; a plurality of micro-pixel controllers provided on the upper surface of the first substrate and configured to control the plurality of micro-pixel packages; and a driver integrated chip (IC) configured to transmit a driving signal to the plurality of micro-pixel controllers, wherein upper ends of the plurality of micro-pixel packages are positioned higher than upper ends of the plurality of micro-pixel controllers with respect to the upper surface of the first substrate.
