Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an input device, and more particularly,
With an input panel composed of flat resistors as the input surface,
Regarding an input device that detects the coordinate data of the pressed position as a coordinate-corrected value by pressing the input surface with a pen or the like, by using a metal anchor for the lead wire of the electrode, The present invention relates to an input device that includes an input panel that has a small area and reduces the number of steps for printing a film that insulates a conductive film from a pattern.

Further, the present invention relates to an input device provided with an input panel that stores correction parameters in the input panel itself and does not require correction processing even if the circuit control board is replaced. 2. Description of the Related Art In recent years, high performance laptop and palmtop personal computers have been developed due to miniaturization, high speed, large capacity, multi-functionality, and low price of microcomputers and memories. Along with this, the number of people who use personal computers is also expanding, the number of people who cannot use conventional keyboards is increasing, and the number of industries in which keyboards are less efficient is increasing. For this reason, a pen input personal computer in which the display surface and the input surface are integrated has begun to be developed, and there is a demand for cost reduction and high resolution of the coordinate detection unit.

In addition, although computers are becoming smaller and lighter and are more often carried and used, there is a limit to the reduction in size and weight of a computer with a configuration using a keyboard as an input means. On the other hand, by adopting a more natural human interface, it is expected to spread to users who are distant from conventional computers. In such a situation, an input device including a coordinate input panel for directly inputting on the screen with a pen or a finger is drawing attention. As an input unit of such a computer, a resistance film type input panel (see FIG. 11 (1)) is used for a model such as an electronic notebook because it is advantageous for thinning and lightweight and low power consumption. , Further miniaturization is required.

[0004]

2. Description of the Related Art First, the operating principle of a conventional input device will be briefly described (see FIG. 3). When only the switches S1a and S2b are turned on, a current flows from the rectifying element group D1 to the rectifying element group D2 via the resistance film, and a potential gradient is created in the X direction. The detection electrode film 102 causes the X coordinate of the contact point. Is detected. At this time, since the rectifying element groups D3 and D4 are reverse biased, no current flows in the Y direction. Next, when only the switches S1b and S2a are turned on, X
Similar to the case of the direction, the potential gradient is generated only in the Y direction, and the Y coordinate of the contact point is detected.

In the conventional input panel, as shown in FIG. 12, the point electrode 115 and the pattern 109 are formed by printing a conductive paste. In such a conventional input panel, the resistance value per unit area of the conductive paste is large so that the resistance value from the point electrode 115 to the connector connecting portion 104 can be ignored with respect to the resistance value on the input surface. Therefore, the width of the lead line must be increased to about 1 [mm], and as a result, the area of the peripheral portion of the input panel becomes large, which makes it difficult to reduce the size.

A method of laminating a plurality of conductive pastes and insulating films may be considered for the purpose of reducing the peripheral portion of the input panel, but the process is complicated, so that the yield is deteriorated and the product cost is increased. Occurs. Also,
The risk of quality deterioration due to poor insulation of the insulating film also increases.

The resistance film 102 formed on the input panel 1
1 and 103-1 (see FIG. 11 (2)),
Generally, resistance unevenness occurs, and in order to perform highly accurate coordinate detection, the configuration of the input device becomes costly. Therefore, the above correction calculation must be performed for each of the X coordinate data and the Y coordinate data. As this correction method, for example, Japanese Patent Laid-Open No. 63-
No. 46531 (coordinate correction method for coordinate detection device) is disclosed. The correction method of the disclosed invention will be briefly described below.

Since the resistance value of the planar resistor in the lower portion 103 of the input panel 1 is not uniform on the surface and there is partial uneven resistance, the planar resistor is divided into regions (see, for example, FIG. See 2)), which region the detected coordinates belong to is determined. The resistance unevenness is two-dimensional, and the detected coordinates (X, Y) are corrected by performing the affine transformation, which is a simple two-dimensional correction method, by using the conversion parameters of each region obtained by the determination. Then, the corrected coordinate (x, y) is obtained.

The affine transformation is expressed by the following equation, and the affine transformation is expressed by the following equation.
You can correct the dimension. x = AX + BY + C y = DX + EY + F (1) where X and Y are measured values, x and y are ideal values (correction values), and A,
B, C, D, E and F are correction parameters. The correction parameters A to F are calculated for each correction area based on the actual measurement values in the above-described correction areas, and the correction parameters for each correction area are stored in the EEPROM 8 (see FIG. 3).

In the conventional input device, this EEPROM is arranged on the circuit control board together with the AD converter 7, MPU 10 and the like. Therefore, there is variation and unevenness in the resistance value for each of the input panels 1, so that even if the input panel 1 is incorporated into the common circuit, the above-described correction must be performed after the incorporation. Therefore, it takes time to ship the device,
Once the correction processing has been performed, the correction processing must be performed again when the circuit control board is reassembled into another circuit control board due to a defect or the like.

[0011]

As described above, in the input panel of the conventional input device, in order to make the resistance value from the point electrode to the connector connection portion negligible with respect to the resistance value of the input surface, Since the resistance value per unit area of the conductive paste is large, the width of the lead wire must be widened,
As a result, the area around the input panel becomes large, and there is a problem that it is difficult to reduce the size. There is also a method of stacking multiple conductive pastes and insulating films for the purpose of reducing the peripheral area of the input panel, but the process is complicated, so the yield is poor, the product cost is high, and the quality of the insulating film is poor due to poor insulation. The risk of is also increased.

Further, in the conventional input device, the input panel 1
Since there are variations and unevenness of the resistance value for each sheet, it is necessary to correct it after incorporating it into the common circuit, so it takes time when the device is shipped, and once the correction process is performed, the circuit control board malfunctions. In the case of reassembling into another circuit control board due to the above circumstances, there is a problem that the correction process must be performed again.

The present invention solves the above problems,
By using a metal foil for the lead wire of the electrode, the area of the peripheral portion of the input panel can be reduced, and the number of steps for printing a film that insulates the pattern and the conductive film can be reduced, thereby providing an inexpensive input panel. The purpose is to provide.

Another object of the present invention is to provide an input device equipped with an input panel which stores correction parameters in the input panel itself and does not require correction processing even if the circuit control board is replaced.

[0021]

In the input device of the first, second, and third features of the present invention, as shown in FIG. 1, a plurality of electrodes 115 formed on the outer peripheral portion of the input panel 1 on the resistive film 103-1 are provided. As a method of drawing the conductive lines from each to the outside of the input panel 1, insulating films on both sides of the metal foil 112 are provided between two resistive films or conductive films 102-1 and 103-1 in the peripheral portion of the input panel 1.

Therefore, even if trouble occurs after the input panel 1 is installed in the input device, it is not necessary to perform a troublesome correction process, and the manufacturer of the input panel 1 is different from the manufacturer of other parts of the input device. Even if the manufacturer of the panel 1 supplies it by OEM, it can be assembled in the apparatus and shipped immediately. That is, the input panel 1 alone can hold the correction parameters, can provide an input device with stable detection coordinates, and greatly contributes to the improvement of reliability.

Similar to the conventional example, the switches S1a and S2 are
When only b is turned ON, a current flows from the rectifying element group D1 to the rectifying element group D2 via the resistance film, and a potential gradient is generated in the X direction, and the detection electrode film 102 detects the X coordinate of the contact point. The detection signal is supplied to the control circuit 110.
At this time, since the rectifying element groups D3 and D4 are reverse biased, no current flows in the Y direction. Next, when only the switches S1b and S2a are turned on, a potential gradient is generated only in the Y direction as in the case of the X direction, and the Y coordinate of the contact point is detected.

FIG. 3 is a sectional structural view of the input panel 1 of the input device of this embodiment. In 3 above, the driving side electrode film 1

The resistance unevenness is two-dimensional, and using the conversion parameters of each region obtained by the determination, affine transformation, which is a simple method of two-dimensional correction, is performed as the correction to detect coordinates (X,
Y) is corrected to obtain corrected coordinates (X, Y).

The affine transformation is expressed by the following equation, and the linear equation is
You can correct the dimension. x = AX + BY + C y = DX + EY + F (2) where X and Y are measured values, x and y are ideal values (correction values), and A,
B, C, D, E and F are correction parameters.

1), ideal value (x1, y1), measured value (X2, Y2), ideal value (x2, y2) at point P2. The values of the correction parameters A to F can be obtained by performing back calculation from these equations.
