Touch display device, touch display method, display and terminal

Abstract

The invention provides a touch display device, a touch display method, a display and a terminal. The touch display device comprises a display panel, a touch panel, a non-touch panel and a touch controller, the touch panel and the non-touch panel are arranged above the display panel, the touch panel forms a touch area, and the touch area comprises a coordinate non-offset area and a coordinate offset area surrounding the coordinate non-offset area; the non-touch panel surrounds the touch panel to form a non-touch area; wherein the size of the touch panel is smaller than that of the display panel, the centers of the display area, the coordinate non-offset area and the touchable area corresponding to the display panel are overlapped with one another, and the shapes of the display area, the coordinate non-offset area and the touchable area are the same but different. According to the technical scheme, the cost of the touch screen, especially a large-scale touch screen, can be reduced, man-machine interaction is more convenient, and compared with a full-size touch screen, for example, multi-point touch control and the like can be achieved, and the problem that the full-size touch screenis prone to being damaged in public occasions can be effectively solved.

Description

technical field [0001] The present invention relates to the technical field of touch screens, in particular to a touch display device, a touch display method, a display and a terminal. Background technique [0002] As human-computer interaction becomes more and more common in various fields, the cost of the touch screen mainly used for human-computer interaction is greatly affected by the size. For example, a 7-inch touch screen costs tens of yuan, while a 32-inch touch screen requires three About four hundred yuan, especially for some public places that need to use a large touch screen, the cost is even more difficult to control. Moreover, for some larger-sized touch screens, the control flexibility is greatly reduced. [0003] In addition, compared with the small-sized touch screen, although the size of the large-sized touch screen increases a lot, the thickness does not change much. The human-computer interaction conditions in public places are often relatively harsh, a...

AI Technical Summary

Problems solved by technology

The human-computer interaction conditions in public places are often relatively harsh, and human-made knocking and damage may occur, resulting in damage to the large-size touch screen, which in turn affects the user's interactive experience and increases maintenance costs for the shopping mall.
