Problems solved by technology

[0004] To this end, it is necessary to provide a display technology solution that supports multi-screen input to solve the problem of multi-display terminals on the market. Each display screen needs to be equipped with a corresponding processor, resulting in high equipment costs, or secondary The screen is subordinate to the main screen and can only passively receive the data sent by the main screen, resulting in poor interactivity and poor sensory experience for users

Embodiment 1

[0049] In the same screen mode, the screens displayed by the first display unit and the second display unit are consistent, assuming that the original display of the first display unit and the second display unit is the first display screen, when the first display unit is used for After receiving the first touch event, the second display unit is used to receive the second touch event, and then the first display image needs to be adjusted. The "processing unit is used to receive and process the touch event correspondingly according to the configuration mode of the current device" includes: the processing unit is used to execute the first touch event and the second touch event, and the original first touch event The first display picture displayed by the display unit or the second display unit is adjusted, and the adjusted first display picture is sent to the first display unit or the second display unit for display. In this way, by invoking the same processor to process touch e...

Embodiment 2

[0052] In the same-screen mode, the first display unit is used to display a second display screen, and the second display unit is used to display a third display screen; the processing unit includes a touch event buffer unit and a touch event execution unit; when When the configuration mode is the simultaneous display mode, the "processing unit is used to process the received touch events according to the configuration mode of the current device" includes: the touch event buffer unit is used to buffer the received first A touch event and a second touch event; the touch event execution unit is used to execute the first touch event on the second display screen, adjust the second display screen, and send the adjusted second display screen to the first display unit and the second display unit for display; or, the touch event execution unit is used to execute the first touch event on the third display screen, adjust the third display screen, and use the adjusted first touch event T...

Embodiment 3

[0056] In the different display mode, the first display unit is used to display a second display screen, and the second display unit is used to display a third display screen; the processing unit includes a touch event buffer unit and a touch event execution unit; when When the configuration mode is the different display mode, the "processing unit is used to process the received touch event according to the configuration mode of the current device" includes: the touch event buffer unit is used to buffer the received first touch event A touch event and a second touch event; the touch event execution unit is used to execute the first touch event on the second display screen, adjust the second display screen, and send the adjusted second display screen to the first display unit; and executing a second touch event on the third display screen, adjusting the third display screen, and sending the adjusted third display screen to the second display unit.

[0057] In this embodiment, t...

Abstract

The invention provides a display method and device for supporting multi-screen input. The device comprises a processing unit and a plurality of display units, wherein each display unit is connected with the processing unit; the display unit is used for receiving a touch event and transmitting the touch event to the processing unit; the processing unit is used for correspondingly processing the received touch event according to the configuration mode of a current device, wherein the configuration mode comprises a simultaneous display mode and an asynchronous display mode. Therefore, each display unit supports user input, interaction between the device and a user is improved, and in addition, the touch events received by different display units can be processed through calling the same processor. Compared with a structure that each display unit is correspondingly provided with one processor, the adoption of the device greatly lowers equipment cost. The device has the characteristics of high interactivity, low cost, wide application scene range and the like.

Description

technical field [0001] The invention relates to the field of computer technology security, in particular to a display method and device supporting multi-screen input. Background technique [0002] With the development of science and technology and the progress of society, mobile terminals have been widely used, and their functions have become more and more abundant. Taking Android devices as an example, with the popularity of Android system devices and the continuous improvement of hardware conditions, various industries have increasingly complex requirements for Android customization functions, among which the input control of the display screen is an important item. [0003] The dual-display and dual-input control of a single-processor system is widely used. For example, in the application scenario of the car machine industry, the central control display navigation is set in the front row, and the rear row can control the video playback through the touch screen; another ex...
