Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data processing apparatus for operating a tablet formed integrally with a display screen by designating points with an input pen.

[0002]

2. Description of the Related Art In recent years, in data processing devices such as personal computers, various miniaturized devices have been developed and sold in consideration of portability. In a data processing device that pursues such miniaturization, the size and operability of the entire device are greatly influenced by what means is used for input operation.

Here, as concrete input means, for example, a key input method using a keyboard, a point input method using a mouse or a trackball, or a transparent tablet integrally provided on the display screen is used. Therefore, a method of inputting by handwriting can be considered.

However, the above-mentioned keyboard method is the most general method for a data processing apparatus, but there is a problem in that it is downsized because a keyboard must be provided separately from the display screen. Also, a method using a mouse, a trackball, or the like must be equipped with these devices outside the main body of the apparatus, and when these are used, a flat space such as a desk is required, which makes it difficult to use when carrying. .

Further, the method of inputting handwriting on a transparent tablet with fingers is advantageous for downsizing because the display section and the input section can be integrated, but it is possible to accurately point a minute position by the size of the fingers. It is difficult to do so, handwriting operation is troublesome in inputting characters, and there is a high possibility of erroneous recognition.

On the other hand, as a personal computer system, a laptop type computer system, which is compact and lightweight in consideration of portability, has been widely used. In such a laptop type computer system, a liquid crystal display (LC) is used as a display device.
Flat panel displays such as D) are used. L used as a flat panel display
In the CD, the brightness and contrast on the display surface are switched by a rotary switch or the like provided outside the LCD body.

Further, a computer system which is more compact and lighter than a laptop type personal computer and has improved portability has been developed and commercialized. In this computer system, instead of the data input by the keyboard as in the conventional system, various data, such as a dedicated pen or tablet,
Since commands and the like are input, it can be said, so to speak, a pen input type computer system. But,
Also in this pen input type computer system, the brightness and contrast on the display surface of the LCD are switched by a rotary switch or the like as in the conventional system.

[0008]

As described above, various input means are conceivable, but each has both advantages and disadvantages, and there is no one suitable for both conditions of use when carried and miniaturization.

Further, the pen input type computer system is designed to be smaller and lighter than the conventional system. Therefore, it is difficult for the user to handle a portable switch or the like by providing a rotary switch or the like which has been conventionally used and switching the brightness or contrast on the display surface of the LCD by the rotary switch. Further, in a pen input type computer system, data is input by a dedicated pen or the like, but it is an efficient operation in such a system to switch the brightness and contrast in the LCD by a rotary switch or the like. I can't say.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a data processing apparatus having an input means which is small in size and light in weight and can be used in a portable manner. Furthermore, according to the present invention, by providing an instruction unit for instructing switching of brightness and contrast in a display device such as an LCD on the tablet,
An object of the present invention is to provide a pen-input type computer system capable of easily switching the brightness and contrast on the display surface of a display device.

[0011]

That is, the present invention provides a tablet input section integrally formed on a display screen and an input pen for designating and inputting an arbitrary point coordinate position on the tablet input section. The system setup screen consisting of multiple items is displayed on the above display screen when a specific position on the tablet is specified at system startup.
Furthermore, when the position on the tablet corresponding to an arbitrary item on the setup screen of this system is designated by the above-mentioned input pen, the setting screen of the item is displayed in the window on the display screen, and the setting screen of the item displayed in this window When the position on the tablet corresponding to an arbitrary candidate value in the inside is designated with the above-mentioned input pen, it is changed and set to the candidate value, and the arbitrary position of the tablet input section integrally provided on the display screen is set. Since the system setup is executed by sequentially designating with the input pen, it is possible to contribute to downsizing and weight saving of the entire apparatus, and it is also possible to use it while being carried.

The present invention also includes a data processing device body,
A display device which is arranged on a predetermined surface of the main body of the data processing device and whose brightness and contrast on the display surface can be switched according to the voltage supplied thereto, and brightness and contrast on the display surface of the display device which is arranged on the display device. Coordinate information generating means for generating coordinate information indicating a touched position, and coordinate information generated by the coordinate information generating means indicates the position of the predetermined instruction portion. Determine if it is coordinate information,
When the generated coordinate information is coordinate information indicating the position of the predetermined instruction unit, a unit that generates switching information that indicates a switching instruction of the predetermined instruction unit, and a storage unit that stores the switching information generated by the determination unit, It has a power supply means for supplying a predetermined voltage to the display device according to the switching information stored in the storage means. With the above-mentioned configuration, a display such as an LCD is displayed on the tablet without providing a rotary switch or the like as in the past. By providing an instruction unit for instructing switching of brightness and contrast in the device, it is possible to easily switch the brightness and contrast on the display surface of the display device.

When is activated, the data currently set in the buffer 57a of the system integration circuit 5 is checked, and a switching command is output from the CPU 50 to the power supply controller 56 according to the data currently set in the buffer 57a.

That is, as described above, the data "0"
Is set in the buffer 57a, a switching command for increasing the brightness and contrast of the LCD 66 is output. If data "1" is set in the buffer 57a, a switching command for lowering the brightness and contrast of the LCD 66 is output.

The power supply controller 56 is connected to the system integration circuit 57 and controls the voltage supplied to each component of the computer system. The power supply controller 56 supplies a predetermined voltage to the LCD 66 and the backlight unit 68 in accordance with a switching command output from the CPU 50 when the BIOS is activated, depending on whether the pointing unit 64a or 64b on the tablet 64 is touched with the pen. As a result, the data is displayed on the display surface of the LCD 66 with a predetermined brightness and contrast. Next, the operation of the pen-input type computer system according to another embodiment of the present invention will be described with reference to FIG. FIG. 21 shows the LCD 66.
3 is a flowchart of a luminance and contrast switching operation on the display surface of FIG.

In FIG. 21, in step F1, the CPU 50 determines whether or not the pointing portion 64a of the tablet 64 is touched. This determination is performed depending on whether or not the coordinate data indicating the position of the instruction unit 64a is generated by the tablet 64 by the pen touch by the user.

When it is determined in step F1 that the instruction section 64a is touched, the tablet controller 65 outputs data "0" to the system integration circuit 57. Upon receiving this data "0", the system integration circuit 57 sets the received data "0" in the buffer 57a (step S2).
