Since the display device includes the above-mentioned touch system, misoperation caused as the edge touch area is touched may be effectively avoided.

FIG. 1 is a schematic diagram of a touch system of embodiment 1 of the present invention;

FIG. 2 is a top view of the touch system of embodiment 1 of the present invention.

To make those skilled in the art better understand the technical solutions of the present invention, the present invention will be further described in detail below in combination with the accompanying drawings and specific embodiments.

As shown in FIGS. 1 and 2 , this embodiment provides a touch system, including a touch screen, a touch position analysis unit 103 and a switch unit 104 . The touch screen includes a center touch area S 1 and an edge touch area S 2 , the touch position analysis unit 103 is used for analyzing a position of a touch on the touch screen, and the switch unit 104 is used for controlling whether a touch on the edge touch area S 2 is effective.

The touch screen provided by this embodiment is divided into the center touch area S 1 and the edge touch area S 2 , and the switch unit 104 controls whether the touch on the edge touch area S 2 is effective. Thus, misoperation caused as software or a program on the edge touch area S 2 is mistakenly touched may be effectively avoided. That is to say, when the position of software or a program to be touched is in the edge touch area S 2 , the switch unit 104 is turned on, then the touch on the edge touch area S 2 is effective, and the software or the program may be driven or opened to execute a command; and when the position of software or a program to be touched is in the center touch area S 1 , the switch unit 104 is turned off, then the touch on the edge touch area S 2 is ineffective, and even if software or a program in the edge touch area S 2 is touched, the software or the program in the edge touch area S 2 is not opened.

The touch position analysis unit 103 of the touch system of this embodiment preferably includes a storage unit and a query unit, and position information corresponding to the center touch area S 1 and the edge touch area S 2 respectively is stored in the storage unit; and specifically, the whole touch screen is stored in the storage unit in a form of coordinates, that is, a group of coordinates corresponds to a touch point (position information). Preferably, the coordinates of the center touch area S 1 and the coordinates of the edge touch area S 2 may be independently stored in the storage unit respectively. The query unit is used for judging whether position information corresponding to current touched position of the touch screen belongs to the center touch area S 1 or the edge touch area S 2 .

When a certain position of the touch screen is touched, whether the touch position is in the center touch area S 1 or the edge touch area S 2 may be judged according to the coordinate information of the position; when it is judged that the touch position is in the center touch area S 1 , a touch command is normally executed; when it is judged that the touch position is in the edge touch area S 2 , whether the switch unit 104 is turned off or on is judged, and at the moment, if the touch command which needs to be executed is in the edge touch area S 2 , the switch unit 104 is turned on and the touch command is executed; and if the touch command to be executed is in the center touch area S 1 , the switch unit 104 is kept off.

Preferably, the touch screen of the touch system of this embodiment includes a display unit 101 for displaying and a touch unit 102 for sensing a touch position. The touch unit 102 may be arranged above the display unit 101 or integrated with the display unit 101 . Further preferably, the display unit 101 is an LCD or an OLED display, of course, may be a display of other types. The touch unit 102 is a resistive touch unit or a capacitive touch unit. The display 101 is combined with the resistive touch unit to form a resistive touch screen, in which contents on the touch screen are operated and controlled mainly on the basis of the principle of pressure sensing. The display 101 is combined with the capacitive touch unit to form a capacitive touch screen, and the transmittance and definition of the capacitive touch screen are superior to those of the resistive touch screen. When a finger of a user touches the capacitive touch screen, the finger and the surface of the capacitive touch screen form a coupling capacitor, so as to realize a touch function.

Preferably, the switch unit 104 is arranged on a side of a frame 105 of the touch screen. Generally, the switch unit 104 is a control button, namely a simple high and low level switch, high level is obtained when the switch is turned on, and low level is obtained when the switch is turned off. The switch unit 104 which is arranged on the side of the touch screen does not occupy the area of the display area (an area for displaying images), so that the frame 105 is narrower and more attractive in appearance. Of course, the switch unit 104 may also be arranged in other position of the touch system.

Preferably, the touch screen is directly divided into the center touch area S 1 and the edge touch area S 2 by hardware, that is to say, the touch screen is divided into the center touch area S 1 and the edge touch area S 2 when being manufactured, or the touch screen is preferably divided into the center touch area S 1 and the edge touch area S 2 under control of software, and the proportion of the center touch area S 1 and the edge touch area S 2 to the whole touch screen may be adjusted according to different conditions.

This embodiment provides a display device, including the touch system of embodiment 1. The display device may be any product or component with a display function such as a mobile phone, a tablet computer, a television, a display, a notebook computer, a digital photo frame, a navigator or the like.

Since the display device of this embodiment includes the touch system of embodiment 1, misoperation caused as the edge area of the touch screen is touched due to too narrow frame may be avoided.

Of course, the display device of this embodiment may further include other conventional structures, such as a power unit, a display drive unit and the like.

It could be understood that, the above embodiments are merely exemplary implementations adopted for describing the principle of the present invention, rather than limiting the present invention. Various modifications and improvements may be made for those of ordinary skill in the art without departing from the spirit and essence of the present invention, and these modifications and improvements are regarded within the protection scope of the present invention.
