A multi-screen display control device is shown, which is linked to a host through a universal serial bus (USB) port to receive image data from the host, and uses a plurality of high-definition multimedia interface (HDMI) ports to output a plurality of HDMI sub-images to a plurality of screens. The multi-screen display control device has a USB hub that couples the USB port to a plurality of graphics processing units (GPUs), so that the GPUs generate the HDMI sub-images based on the image data transferred from the host via USB communication technology.

A terminal device such as a smartphone displays a first image on a display unit, and outputs a second image including the first image as a part to a display device such as a navigation device. Also, the terminal device obtains relative position information indicating a relative positional relation of the first image with respect to the second image from an external server. When a user makes a touch input to the second image displayed on the display device, the input position is transmitted from the display device to the terminal device. The terminal device obtains the conversion necessity information indicating whether or not the input position on the second image needs to be converted based on the relative position information, and converts the input position on the second image to the input position on the first image based on the relative position information when the conversion is necessary.

A display system includes a first display device having an active display region having individually controllable pixels, a sensor to generate information that is useful for determining a position of the first display device relative to a second display device, and a display controller to determine the position of the first display device relative to the second display device based on the information generated by the sensor. The display controller determines an image to be shown on the first display device based on the position of the first display device relative to the second display device.

An electronic device comprises: a plurality of scalers for processing respective images of a plurality of content received from a plurality of sources devices; and a processor configured to change information on whether at least one scaler of the plurality of scalers supports high dynamic range (HDR) when a request for simultaneously displaying the plurality of content is received.

A display system including a host processor and a display driver integrated circuit may be provided. The host processor may generate a clock signal that swings swinging between a high level and a low level, generate and output a first synchronization signal based on the clock signal, generate a wakeup interrupt by measuring a frame update period of a display panel, generates frame data based on the first synchronization signal by enabling an image providing path based on the wakeup interrupt, and output the frame data for every frame update period. The display driver integrated circuit may receive the first synchronization signal and the frame data from the host processor, and control the display panel such that a frame image corresponding to the frame data is displayed on the display panel based on the first synchronization signal without storing the frame data.

The present application relates to the field of display technology, and discloses a display module test platform, including a core processor. The core processor is capable of supporting installation of a terminal operating system. A display output terminal of the core processor is connected to a display module to be tested. The display module to be tested includes a touch structure. The touch structure and the core processor communicate with each other via an Inter-Integrated Circuit (I2C) bus.

A host processor includes a high-speed driver which generates first high-speed data, a coupling circuit which receives the first high-speed data from the high-speed driver, and removes a direct-current (“DC”) component of the first high-speed data to generate second high-speed data, a low-power driver which generates low-power data, and a passive switch which receives the second high-speed data from the coupling circuit, receives the low-power data from the low-power driver, and selectively outputs the second high-speed data or the low-power data to a display apparatus.

The present disclosure provides a method of controlling a high-definition multimedia interface (HDMI). The method includes: reading, by a source device, extended display identification data (EDID) of a sink device when the sink device and the source device are connected; writing information about the source device in a status and control data channel (SCDC) structure; and reading, by the source device, the EDID again based on a predetermined field value included in the SCDC structure.
