Description of the invention: [Technical field to which the invention pertains] ^ A method for correcting a flexible board, in particular, the "preparative board is flexed to form a specific shape" and the flexible board is still normal The input touch function is performed. [Prior Art] The conventional display panel is made of a rigid material f, and it is impossible to perform the function of outputting the electronic device of the periphery of the device. Although it can be used to perform certain functions, it is made of a rigid material and cannot be flexed. The flexible touch panel can have other additional functions, that is, the flexible characteristics can be used to make the flexible board. When flexed into different shapes, they can have different functions respectively. However, because the flexible board has flexible characteristics, the sensing of the touch input needs to be corrected to provide the user with more practical requirements. SUMMARY OF THE INVENTION The present invention provides a method of correcting a flexible board. The flexible board includes at least one sensor, which may be built in or externally attached to the flexible And the method of the present invention comprises: providing the flexible board, and the flexible board can be bent to form a special shape; receiving a first deflection value 'rich flexible board to form the specific shape When the first buckling value is measured by the sensor, the first buckling value and the comparison table are compared; and a correction signal is transmitted according to the comparison table, so that the flexible board performs a 3 201033863 identification function according to the correction signal. In this embodiment, the correction signal includes a smart touch filter signal, a touch point offset signal, or a negligible error, and the method of the present invention further includes a specific shape that is an overlap of the shirt; If the flexible board is cut, the correction signal is adjusted.

Preferably, the present invention further determines whether the particular search is between G-2G seconds; if the determination is "Yes", the signal is positive. In the above embodiment, the flexible board mainly transmits the correction signal according to the comparison table, so that the flexible board performs the identification function according to the correction signal. However, the present invention can also define a correction signal according to the flex shape of the flexible board itself, so that the flexible board performs an identification function according to the correction signal. The present invention therefore provides a method of correcting a flexible board. The flexible board includes a sensor. The sensor can be built into the flexible panel' The method of the present invention comprises: providing the flexible plate, and the flexible plate can be flexed to form a specific shape; receiving a first deflection 4 201033863 value, when the flexible plate forms the specific shape, (d); a deflection value; a receiving-second deflection value, passing the - characteristic = the detector measures the second deflection value; determining whether the = _-the amount of the second deflection value is between - deflection The value ^ = judged as "yes" to transmit a correction signal so that the bypassed board performs an identification function in accordance with the correction signal. [Embodiment]

= The flexible board has flexibility (four), so the sense of touch wheeling 'to be corrected' to provide users with more practical requirements. Please refer to Fig. 1Α·10 for several types of flexible plates that may be deflected: for example, s-curved, curved or cylindrical. The figure ia_ic is only for illustration, but the invention is not limited thereto. = 2A - 2C shows several possible flexural shapes of the flexplate 2 with the sensor 21_23, which are similar for the purpose of illustration and are not intended to limit the invention. Taking Fig. 2C as an example, when the flexible board 2 is bent into an arc shape, it is judged by the correction method of the present invention that the user's finger 3 is performing a certain adjustment. The various embodiments of the method of the present invention are described in detail below. Referring to the flow chart of Fig. 3A, first step S31 is provided with a slanting plate and the slab can be bent to form a specific shape. As shown in Figs. 1A-1C or 2A-2C, the flexible sheets 1 or 2 can be flexed into various shapes. Hereinafter, the flexible board 2 of Fig. 2C will be described as an example to avoid a few lengths of description. The flexible board 2 includes at least one sensor 21-23, such as a stress sensor 21_23. The specific shape described above may be judged on the basis of the force value or the electronic signal generated by stress (including pressure, compressive force, tensile tension, shear force, etc.). The sensor 21-23 of the present invention can be a stress sensor, an optical sensor or a shock sensor. The stress sensor can be a piezoelectric sensor, a capacitive sensor, an inductive sensor or a resistive sensor. However, the invention is not limited thereto.

Returning to Fig. 3A, step S32: receiving a first deflection value' When the flexplate forms a particular shape, the first deflection value is measured by the sensor. Referring to FIG. 2C at the same time, for example, when the flexible board 2 is formed in an arc shape before the user's finger 3 touches, the first deflection values can be measured by the sensors 21, 22, and 23, respectively, to -0.5, -0.5, -0.5. . Next, in step S33, a second deflection value is received, and after the lapse of a certain time, the at least one sensor measures the second deflection value. For example, after a specific time of 0.2 seconds, since the user's finger 3 touches the flexible board 2, the sensors 21, 22, 23 respectively measure the second deflection values of -0.35, -0.4, -0.5. Next is step S34: determining whether a change amount between the first deflection value and the second deflection value is within a deflection range. This range of deflection can be varied by the designer depending on the sensor. In the example of FIG. 2C as described above, the deflection range can be set to ±0.2, and the amount of change between the first deflection value and the second deflection value is 0.15, 0.1, 0', respectively, still in the deflection range. Within (±0.2). Therefore, step S36 can be performed next: a correction signal is transmitted so that the flexible board 2 performs the identification function according to the correction signal. If the change between the first deflection value and the second deflection value is 6 201033863, the amount exceeds the deflection range 'this time has exceeded the normal', touch, and the action will therefore return to step S33 to re-receive the second Flexural value. Or alternatively, in another embodiment, if the amount of change between the first deflection value and the second deflection value exceeds the deflection range, the flow may return to step S32 to re-receive the first deflection value. .

In the embodiment of Fig. 3A, the correction signal is transmitted as long as the amount of deflection change exceeds the deflection range. In a preferred embodiment, however, the present invention may also incorporate time factors to make the determination more precise. Referring to FIG. 3B, before transmitting the correction signal (step S36), the present invention further performs step S35: determining whether the specific time between the first deflection value and the second deflection value is between 0-20 seconds; If YES, the correction signal is transmitted (step S36). In other words, if the specific time between the first deflection value and the second deflection value is too long, the comparison of the first deflection values is necessary to be reset. Therefore, if the determination in the step S35 is "NO", Then the flow returns to step S32: the first deflection value is re-received. As shown in the example of Fig. 2C, since the amount of change of the sensors 21, 22, 23 is 0.15, 0.1, 〇, respectively, the stress position (stress of the user's finger 3) can be calculated by this, for example, left. The area is two centimeters to the right, and the stress level is Level 3. (The degree of stress can be based on different sensors, and the materials are the same as the comparison table, which is only exemplified here, not limiting the invention). Therefore, the flexible board of the present invention can perform the identification function according to the correction signal. Step S41 is also made: determining the specific shape of the flexible board: Yes 4 No: Enter 7 201033863 and if the determination is YES, the correction signal is adjusted (Step S42). Please refer to FIG. 4A and FIG. 4B (FIG. 4B is a top view of FIG. 4A). 'If the flexible board is deflected, 'the overlapping portion 41 is formed, and the sensitivity and the non-overlapping portion of the portion should be There is a difference, so it is necessary to adjust the correction signal. In another embodiment, the present invention also utilizes a look-up table to transmit correction signals. Please refer to the flowchart of FIG. 5. First step S5i: a flexible plate is provided, and the flexible plate can be flexed to form a specific shape. This step is similar to the step SS1 of Fig. 3, and therefore will not be described again. Next, in step S52, a first deflection value is received. When the flexible plate forms a specific shape, the first deflection value is measured by at least one sensor. Similarly, step S52 is similar to step S32' of Fig. 3 and will not be repeated.

Then, in step S53, the first deflection value is compared with a comparison table. This comparison table may be defined by the designer according to different sensors or flexible boards, and different comparison tables are defined. As exemplified herein, Table 1 shows the deflection values of the various sensors when flexed into the various specific shapes of Figures 2A-2C. Table 1 Sensor 21 Sensor 22 Detector 23 State a (Fig. 2A shape) 0 0 0 State b (Fig. 2B shape) 0 -1 0 State c (Fig. 2C shape) -0.5 -0.5 0.5 8 201033863 Represents that the flexplate is flexed into a variety of specific shapes (state A kg can correspond to A_c.

Therefore, the deflection value measured by the eight-sensor is the same as that of Table 1. If the table is the same, the plate forms the specific shape, and then the specific value is given according to the setting of Table 2. As the correction signal, the flexibility can be obtained. The board is based on the correction signal; the display function is shown (step S54 of Fig. 5). Further, according to the specific setting values of the ., , and the table, as the correction signal and according to the correction = the flexible board will re-correspond to the internal positioning of the original touch plane and the curved plane to perform the correct identification function. . For example, if the user flexes the flexible board into a U-shaped or cylindrical type and puts it on the wrist (not shown), the flexible board may be pressed against the table by the user's wrist. At this time, the touch generated by the flexible plate pressing to the side of the table can be regarded as an error signal. In another example, if the flexplate is flexed into an arc, the touch offset of the curved surface is also required to correct the user's touch position. Similar to Fig. 4 described above, since the different portions may have different degrees of bending when flexed, the present invention may further judge whether or not there is an overlap portion and give different set values. For example, the overlapping portion 41 of FIG. 4A or 4B should reduce the sensitivity setting, and the error 201033863 2 filter is closed, and even any touch action of the overlapping portion is completely omitted in the preferred embodiment, except that the direct transmission is performed according to the comparison table. In addition to correcting the signal, the present invention may also add a time factor to determine the transmission of the signal. Referring to FIG. 6A and FIG. 6B, the steps s are similar to each other, so the description will not be repeated. ❹

In the embodiment of the circle 6', after the step S63, the second deflection value is received again after a certain time (step S64). This step is substantially similar to the step S33 of Fig. 3A, and therefore the description is not repeated. The next step S65 can refer to the above-mentioned judgment of step S34 of FIG. 3A. The difference in this embodiment is that when the judgment of step S65 is "YES", the flow proceeds to step S67: according to the comparison table, the transmission f is positive. The signal is such that the flexplate performs similar functions according to the correction signal. In the embodiment of FIG. 6B, time is further added to transmit a more accurate correction signal. As shown in FIG. 0B, before step (6), step S66 is performed: further determining whether the elapsed time between the first: the mediator is between a specific time, for example, seconds, and if the determination is "Yes", the basis is In the comparison table, the calibration value is transmitted. In other words, if the first deflection value and the second replacement curve are too heavy, the ratio of the first deflection value is again 疋, so if the judgment of step S66 is "No" returns to step S62: re-receiving the first deflection value. Although the present invention has been disclosed above in a preferred manner, it is not intended to limit the present invention to 201033863, and anyone skilled in the art will not In the spirit and scope of the invention, the scope of protection of the present invention is defined by the scope of the appended claims.
