The present disclosure provides a switch, which includes a first input port, a second input port, an output port and a control circuit. The output port outputs image data received by the first input port. The control circuit receives a first electrical characteristic and a second electrical characteristic from the first input port and the second input port respectively, and changes a third electrical characteristic of the output port when the second electrical characteristic is different from the first electrical characteristic, and then the output port outputs image data received by the second input port.

The present disclosure relates to a data transmission and reception method of a data driving device and a data processing device as well as a data transmission and reception system, and more particularly, to a method and a system in which the data driving device receives an initial configuration value from the data processing device, stores the initial configuration value as a configuration restoration value, and rapidly restore an environment for a high-speed communication by using the stored configuration restoration value when a link between the data processing device and the data driving device is lost so as to reduce a time for restoration.

The present invention provides a display device. The display device includes a timing controller, a data register, a source driver, and a display panel. A portion of a vertical effective display column data in a vertical idle period is output through the data register, which can increase a sum of charging time of a pixel column of an entire frame of images. Moreover, an N/2th horizontal idle period to the Nth horizontal idle period are adjusted to improve display uniformity of an upper half screen and a lower half screen.

A display system and a display device are provided. The display system includes a host device, a display device and an input device. The display device includes a display controller, a display panel and a USB hub. The display controller processes an image signal provided by the host device with a first processing mode and displays the processed image signal on the display panel. The USB hub is coupled to the host device. The input device is coupled to the USB hub. The input device forms a first signal input path with the host device via the USB hub and a second signal input path with the display controller via a signal line. The input device transmits the control signal via the signal line to cause the display controller to process the image signal with a second processing mode and display the processed image signal on the display panel.

A system includes an electronic module and an integrated circuit outside the electronic module. The integrated circuit is configured to generate a digital timing signal that emulates a first synchronization signal internal to the module and not available outside the module and to generate trigger signals based on the digital timing signal. A controller is configured to independently and autonomously perform control operations of the electronic module at times triggered by the trigger signals.

The present invention relates to a signal processing device and a video display device having same. A signal processing device according to one embodiment of the present invention comprises: a decoder for decoding first video data from a first video source and second video data from a second video source to output decoded first video data and decoded second video data; a video quality processing unit for, when a common frame rate is set on the basis of a first frame rate of the first video data and a second frame rate of the second video data, outputting the first video data on the basis of the common frame rate; and a graphic processing unit for outputting the second video data on the basis of the common frame rate. Thereby, it is possible to process a plurality of video data in synchronization.

Circuitry for adjusting luminance of a display device is provided. The circuitry includes a non-volatile memory array having a plurality memory cells configured to store luminance data of the display device, and a luminance adjusting circuit configured to receive image data to be displayed on the display device. The luminance adjusting circuit is coupled directly to the non-volatile memory array to receive the luminance data of the display device from the non-volatile memory array and adjust the image data based on the luminance data of the display device.

A case for a cartridge for a vapor provision device is configured such that opening the case involves a coordinated action using both hands. In some implementations, the case includes a first housing portion and a second housing portion which come together to contain and enclose the cartridge when the case is shut and separate to open the case to allow access to the cartridge.

An information processing method, a device, and a storage medium, which relates to a screen transmission technology, are provided. The method includes: in response to a first operation acting on characters, displaying the characters in an input box, where the input box is an input box of a screen transmission application; determining a target screen-transmission code in candidate screen-transmission codes stored in a screen-transmission sending end according to input characters, where the number of characters contained in the target screen-transmission code is greater than the number of the input characters, the target screen-transmission code contains the input characters, the target screen-transmission code is a screen-transmission code of a screen-transmission receiving end, and the target screen-transmission code is acquired by the screen-transmission sending end from a beacon received from the screen-transmission receiving end; displaying the target screen-transmission code in the input box.

Systems, apparatuses, and methods for performing asynchronous memory clock changes on multiple displays are disclosed. From time to time, a memory clock frequency change is desired for a memory subsystem storing frame buffer(s) used to drive pixels to multiple displays. For example, when the real-time memory bandwidth demand differs from the memory bandwidth available with the existing memory clock frequency, a control unit tracks the vertical blanking interval (VBI) timing of a first display. Also, the control unit causes a second display to enter into panel self-refresh (PSR) mode. Once the PSR mode of the second display overlaps with a VBI of the first display, a memory clock frequency change, including memory training, is initiated. After the memory clock frequency change, the displays are driven by the frame buffer(s) in the memory subsystem at an updated frequency.
