Embodiment Construction

[0038] As mentioned in the background section, when an electronic device with a touch function is in a projection-only mode in the prior art, the display screen on the large screen cannot be operated by touching the display screen of the electronic device.

[0039] The inventor found that this is because the electronic equipment with touch function in the prior art uses the absolute coordinate input method when corresponding the touch position to the corresponding position on the display screen, that is, on the touch screen Define a reference point (such as the lower left corner of the touch screen), and correspondingly define a reference point (such as the lower left corner of the display screen) on the display screen, and then divide the touch screen and the display screen into multiple horizontal and vertical The intersecting grids are respectively recorded as x coordinates and y coordinates. When touching, it is only necessary to calculate the horizontal displacement and ve...

Abstract

Embodiments of the invention disclose a control method and a control system for an electronic apparatus with a touch function. The method comprises: detecting a current working mode and a current coordinate input mode of the electronic apparatus; and when the current working mode of the electronic apparatus is switched to a projection-only mode, controlling the coordinate input mode of the electronic apparatus to be switched to a relative coordinate input mode. According to the control method provided by the embodiment of the invention, only relative displacement between a start point and a stop point of a touch track on a display screen of the electronic apparatus needs to be detected, and a to-be-operated position on a large screen is controlled to be moved for the same relative displacement, so that a display image on the large screen can be operated by touching the display screen of the electronic apparatus, and the problem of incapability of operating a display image on a large screen by touching a display screen of an electronic device when the electronic device with a touch function is in a projection-only mode in the prior art is solved.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to a control method and control system of an electronic device with a touch function. Background technique [0002] With the development of science and technology, electronic devices with touch functions in the prior art support multiple working modes, one of which is a projection-only mode. In this projection-only mode, the display screen on the electronic device can be projected to Realize projection display on the big screen. However, in the prior art, when an electronic device with a touch function is in the projection-only mode, its display screen will go out, that is, it will be in a black screen state, so that it is impossible to match the position on the display screen of the electronic device with the picture displayed on the large screen. Precise alignment of the position of the electronic device results in the inability to operate the display screen on the ...
