Abstract

PURPOSE:To facilitate the control of the input information at selection of menus, etc., and at the same time to simplify the application software by providing a touch panel to designate the optional position coordinates and an output means for character codes. CONSTITUTION:Each character shown on a display 3 corresponds successively to the addresses stored in a VRAM respectively at and after the upper left position of the display 3 with a display device 2 containing an input function which a touch panel 4 is overlapped on the display 3. Then the coordinates 1-40 can be designated in the (x) direction and the coordinates 1-25 in the (y) direction respectively with push of an optional point of the panel 4. Therefore the addresses of the VRAM are calculated in response to the positions of the (x) and (y) coordinates from these coordinates obtained with push of an optional point on the panel 4. Then the character codes are read out of the obtained addresses and outputted to a computer main body 1. Thus it is possible to simplify the application software since the input information can be easily controlled at selection of menus.

Description

[Detailed Description of the Invention] [Field of Industrial Application] Is the present invention a display? The present invention relates to tN, and particularly to a display device with an input function that has an output function to a computer main body.

[Prior Art] As shown in FIG. 3, a conventional display device with an input function outputs the pressed position coordinates on the touch panel 7 to the computer main body 5, and application software running on the computer main body 5, These position coordinates, the positions of characters displayed on the display 6, and character codes were controlled.

[Problems to be Solved by the Invention] The above-described conventional display device with an input function has the disadvantage that the pressed position information is sent to the computer main body 5, so the application software that controls this information is complicated.

[Means for Solving the Problem] In order to specify arbitrary position coordinates on the display, an uninvented display device with an input function uses a code of characters displayed at a specified position with respect to the touch panel, that is, from the touch panel. The data stored in the address on the VRAM corresponding to the position information of is output.

Specifically, the display device with an input function of the present invention includes a touch panel attached to the display surface for specifying arbitrary positional coordinates, and a VRAM that corresponds to the positional coordinates from the touch panel displayed at the specified position. The computer is characterized by having means for outputting code data of characters stored at the address of the computer to the main body of the computer.

[Example] Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention. By pressing a point on the display surface of the display device 2 with an input function, the code value of the character displayed at the pressed position is output to the computer main body l.

FIG. 2 shows the configuration of the display device 2 with an input function shown in FIG. 1, in which a touch panel 4 is mounted on a display 3 in an overlapping manner. Each character displayed on display 3 is
They correspond to addresses on the T/RAM in order from the top left. By pressing any point on the touch panel 4, 1 to 40. Coordinates from 1 to 25 can be specified in the y direction.

Therefore, from the x and y coordinates obtained by pressing an arbitrary point on the touch panel 4, the address on the VRAM corresponding to this position is calculated, and the character code stored at the calculated address is read out. The character code is output to the computer main body l.

For example, suppose that the position where the number "1" of "1: word processor" shown in FIG. 2 is displayed is pressed on the touch panel 4. The touch panel 4 sets x=10. y
The coordinate 7 is specified, the corresponding address on the VRAM is found from this position information, and the data stored at this address, that is, the code of the number 1, is read out. This code is computer main unit 1
On the computer main body 1 side, application software receives this code and selects a word processor function. Note that there are no identical numbers in the display contents, and if a code other than numbers is sent, it will not work.

[Effects of the Invention] As explained above, the present invention outputs the code of characters displayed on one screen to the computer main body.
It is now possible to easily control input information in situations such as menu selection, and has the effect of simplifying application software compared to the past.
