Abstract

PURPOSE:To reduce the load of an application program by providing a unification defining means for an input device and a display device to prescribe simultaneously the operation of both of the input and display devices. CONSTITUTION:A touch panel 5 serves as an input device and a display device like an LCD 7, etc. is set at the lower side of the panel 5. This input device contains a CPU 1, a ROM 2, a RAM 3, etc. Then a unification defining means (input/output driver) 22 for an input part and the display device is provided on the ROM 2 and receives the commands for input and display from an application program 21 working on the RAM 3. Then the means 22 defines the key information to a key table set on the RAM 3 and at the same time writes the display data to a VRAM 8 through a display control device 6 to display it on the LCD 7. Thus both display and input devices can be treated as a unified matter when the program 21 delivers a key defining command to the means 22.

Description

Detailed Description of the Invention [Industrial Application Field] The present invention has a touch panel such as a handheld terminal as an input Km, and has an hcD on the lower side of the touch panel.
The present invention relates to an input device for equipment having a display device such as the above.

[Conventional technology]

When placing a touch panel in front of a display IT such as an LCD and displaying guidance for manual operation on the display device to specify manual operation of the lid on the touch panel, conventional input/display control mechanisms do not allow input Control of the device and display device had to be performed independently, and the application program had to control both the input device and the display device separately.

[Problem that the invention seeks to solve]

However, with the above-mentioned conventional technology, even when the two are closely related, such as in an information system that has a display device such as an LCD and an input device such as a touch panel, display IT is controlled and input IT is controlled at the application level. There are problems in that it is necessary to perform control individually, the load on the application program is large, and the efficiency of program creation is low. Therefore, the invention is intended to solve these problems, and its purpose is to provide information to both the input device and the display device at the same time. By means of an integrated definition means that makes it possible to define key definitions at the application level, at the same time the LCD corresponding to the corresponding position is defined.
To provide a device for displaying essential guidance on a vertical display screen.

Means for Solving Problem C] Input section of the present invention [position information corresponding to the pressed position on the bottom edge panel?] an input unit including an input recognition unit that generates an input and a key table that provides a key code in accordance with the position information; a display data output unit that displays on an LCD screen located below the human power recognition unit; The display data output section?
It is composed of a display section consisting of a display control device that controls the input section, and an input/output driver that simultaneously defines the input section and the display section, and an application program issues commands to the input/output driver.

Is it possible to integrally define the input section and the display section as if they were the same device? Features.

[Effect]

According to the human-powered KtK of the present invention, when an application program outputs a key definition command including guidance display information to an input/output driver, the input/output driver stores a key code in a key table corresponding to a designated input position. At the same time, the designated guidance is displayed using the display control device on the display corresponding to the designated input position. When the user presses the relevant guidance part, the input/output driver uses the input recognition unit to pass the defined key code corresponding to the pressed position to the application program for writing purposes.

The application program is the water entry device and input deviceff
, ' can be treated as integrated with ', achieving efficient processing.

[Implementation row]

The present invention will be explained in detail below.

Figure 1 is a block diagram showing an actual tU sequence of the present invention. Integration of the input section into the display section (Ota Kadriver) Exists on iJROM2.It receives commands regarding input and display from applications running on RAM3, and according to the instructions, keys are stored in the key table on RAMa. At the same time as defining the information ft, display data is written to the VRAM 81/() throughout the % display control device ji6, and the display control device displays the VRAM 8 on the LCD panel 7.

When the user presses an input detection point on the touch panel 5, the input control device 4 notifies the central processing unit IK of this through an interrupt 4. The central processing SFC 1 passes control to the input/output driver.

The input/output driver uses the input control device 4 to check the input detection point and passes it to an application that extracts all the key information on the key table corresponding to the detection point.

Next, the operation of the present invention will be explained based on FIG. 2, FIG. 3, and FIG. 4. -Figure 2 shows the flow of control.
The application program 21 specifies the input and display integration definition means (input/output driver) 22 using command data having information regarding input and display shown in FIG. The input/output driver 22 operates according to the key block position and key code contained in the above-mentioned lever.
Is the key code specified in the key table on RAM3? At the same time as setting, the attributes, mode,
to the display control device 6 based on display data.

The LCD panel 7) corresponding to the above-mentioned keep lock displays the guidance for specifying at the position.

Attributes include 1 inversion, vertical ruled lines, horizontal ruled lines, etc., and mode designations, graphic data, character data, etc. can be selected as guidance.

FIG. 3 is a conceptual diagram showing the state at this time. A key code is defined in the key table corresponding to the specified key lock 51 of the touch panel 5), and the specified guidance is displayed on the display pirate 71 on the LCD panel 7 at the position corresponding to the specified key lock.

When the user presses the grayed out guidance part 71 on the CD panel 7, the corresponding touch panel 5
The upper detection point 51 is pressed. In response to the above-described pressing operation, the input training device 4it uses an interrupt to interrupt the central processing unit 1 to notify the input/output driver B of this fact. The input/output driver 22 is.

Check the pressed position on the touch panel 5 using the Jinrikikun Gokyo Sagi 4, find the position on the key table 31 corresponding to the vertical position of the pressed position, retrieve information such as the key code stored in the key table 31Vc, The information is passed to the application program 21.

〔Effect of the invention〕

As described above, according to the present invention, there is provided an input device and a display device integration definition means, and the integrated definition means defines an input device such as a touch panel and a display device such as an LCD panel at the same time. In addition, the application program can be treated as a combination of a display device and an input device t-, which has the effect of reducing the load on the application program and realizing efficient processing.
