Abstract

PURPOSE:To shorten the control time and to reduce the cost, and also, to prevent a change with the lapse of time from being caused by constituting the title system a program stores a coordinate input value in a prescribed position. CONSTITUTION:In a touch panel control mode, an MPU 101 displays four reference positions (+ display) of x0, y0; x0, y1; x1, y0; and x1, y1 on a CRT 103 through a CRT control circuit 102. With respect to these reference positions, by touching on a touch panel 105 with a jig bar 104, coordinate data is transmitted to the MPU 101 through a touch panel control circuit 106, and this coordinate data is set to a nonvolatile memory 107. These series of setting operations are executed by a program stored in a memory 108. In such a way, the time required for the control becomes an extremely short time, a fitting system of high strength can be adopted, and a change with the lapse of time caused by vibration and impact can be prevented.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention provides a touch panel position adjustment method that allows easy position adjustment of a touch panel and a display device provided corresponding to the touch panel. % [Conventional technology] Conventionally, in a display device with a touch panel,
For example, as disclosed in Japanese Unexamined Patent Publication No. 58-178152, when adjusting the relative position between a touch panel and a corresponding display device, the mechanical mounting of the touch panel or display device changes the position. It was supposed to be adjusted by letting it go.

[The problem that the invention attempts to solve]

In the above-mentioned conventional technology, the touch panel, which has a physically fixed position, and the display device, which also has a physically fixed position, are tried to be aligned by changing their relative positions, so the following problems arise. was there.

(1) Adjustment work must be performed while loosening fastening parts such as screws, which takes a long time and increases manufacturing costs.

(2) The metal fittings used to attach the touch panel or display device must be adjustable, which increases manufacturing costs.

(3) - Even if it is fixed once, the position may change over time due to vibration or impact.

The present invention has been made in view of the above circumstances, and aims to solve the above-mentioned problems in the conventional technology, shorten the adjustment time, reduce costs, and prevent aging. The purpose of the present invention is to provide a touch panel position adjustment method that is easy to use.

[Means to solve the problem]

The above object of the present invention is to provide a display device with a touch panel having a touch panel for detecting a coordinate position and a display device provided corresponding to the touch panel, in which coordinates can be input to the touch panel using the resolution of the touch panel. a reference position is displayed on the display device, and coordinates are displayed on the touch panel corresponding to the reference position by the input means. This is achieved by a touch panel position adjustment method characterized in that absolute coordinates obtained by input are stored in the nonvolatile memory.

[Effect]

In the touch panel position adjustment method according to the present invention,
Since the program stores the coordinate input values from the input means at a predetermined position, the time required for adjustment is extremely short, and the touch panel.

Since the display device can be mounted in a fixed position, the metal fittings used for mounting can be simple, which has the effect of avoiding an increase in manufacturing costs.

Furthermore, according to the touch panel position adjustment method according to the present invention, a high-strength mounting method can be adopted, so aging due to vibrations and shocks can be prevented, and the aging of device parts including the touch panel and display device can be prevented. It also has the effect of being easily readjustable in response to changes.

〔Example〕

EMBODIMENT OF THE INVENTION Below, one embodiment of the present invention will be described in detail based on the drawings.

The first Wi shows the hardware configuration of an embodiment of the present invention. In the figure, 101 is a microprocessor (hereinafter referred to as rMPUJ), and 102 is a CRT control circuit (C
RTC), 103 is a CRT, 104 is a jig rod to be described later,
105 is a touch panel, 106 is a touch panel control circuit (TPC), and 107 is a nonvolatile memory.

Each element arranged as described above operates as follows.

In touch panel adjustment mode, the lMPU 101
%Xoe on the CRT 103 via the control circuit 102
Vo: Xotyx; Xxeyo; Displays the four reference positions (+ display) of Xx*yi. By touching the touch panel 105 with the jig rod 104 with respect to this reference position, the coordinate data is transferred to the touch panel control circuit 105.
6 to MPUl0I.

This coordinate data is set in the nonvolatile memory 107.

These series of setting operations are executed by a program stored in memory 108.

FIG. 2 shows an example of the operation flow of the above program along with an example of a guidance screen. First, the program determines whether the touch panel is in the position adjustment mode based on the states of switches, etc. (not shown) (step 300).

If it is the position adjustment mode, first, a lower left corner input instruction screen 500 is displayed (step 400) to prompt input. When the adjustment operator inputs the positions of + and - on the screen using the aforementioned jig rod (step 410), the program selects an X corresponding to the lower left corner. .

y, coordinates are read (step 420).

Thereafter, input instruction screens 501, 502, and 503 are similarly displayed for the upper left, upper right, and lower right corners, and the adjustment operator is made to input.

The y-y coordinates are read (steps 401 to 423).

After the above operation, in confirmation screen display step 430,
The guidance screen 510 is displayed and the adjustment operator is asked to check whether the input is correct (step 440).
), if there is no problem, end the adjustment 0 If there is a problem,
Redo the adjustment from the beginning.

FIG. 3 shows the touch panel coordinate relationship assumed in this embodiment. For the entire touch panel, the X direction O
~1399. It has a resolution of 0 to 1199 in the Y direction, and 1
It is a 400 x 1200 matrix.

The effective area is 100 in the X direction when properly set.
~1299. Y direction 100 to 1099 and 1200
It is a matrix of x1000. If the minimum recognition area is 100×100, there will be a 10×12 area.

FIG. 4(a) shows a state in which the touch panel is set normally, and FIG. 4(b) shows a state in which the touch panel is set at an angle.

When the touch panel is properly set, the settings on the nonvolatile memory 107 are as shown in FIG. 4(a), and the area 0O-02 (see FIG. 3) is 100
Separated by 100 blocks. That is, block 00 is (100,100), (100,109),
(109,100).

This is an area delimited by (109, 109). When operating the touch panel, a program recognizes the settings on the nonvolatile memory 107 and identifies blocks.

When the touch panel is set tilted from its normal position, the settings on the nonvolatile memory 107 will be as shown in FIG. 4(b), and the block 00 will be (90,7
0), (90,78), (98,70), (98
, 78). In this case as well, when operating the touch panel, this non-volatile memory 107
The program will recognize the above settings and identify the block.

According to the above embodiment, the following effects can be obtained. That is, (1) Since the touch panel is adjusted electronically, the adjustment time is significantly shortened.

(2) The touch panel and display device can be installed using simple metal fittings, reducing costs.

(3) Since the touch panel and display device are fixedly mounted, there is little change over time, and even if changes occur,
Can be easily readjusted.
