Description

Reporting device and method

The present invention relates to a reporting device, and more particularly to a reporting device suitable for a touch panel.

Touch panels have become a new trend in display technology, and human-computer interaction can be easily performed almost by touching the panel, and such convenience is mainly attributed to multiple sensing modules disposed on the panel.

In practice, each sensor module will have a corresponding sensing intensity due to the pressure of the panel, and the latter circuit will use these inductive strengths to linearly estimate which target on the panel is clicked. However, the sensing intensity of the sensing module is nonlinearly related to the sensing distance, so the estimated point coordinates are less than ideal, often resulting in undesirable panel operations. For example, a hand-drawn straight line on the panel is recognized as a curve; pressing an option displayed on the panel performs another adjacent option operation.

Accordingly, it is an object of the present invention to provide a reporting apparatus and method that more accurately locates which one of the panels is clicked on.

Therefore, the reporting method of the present invention is applicable to a panel provided with a plurality of sensing modules, and each sensing module sends a sensing data due to the pressing of the panel, and the reporting method comprises the following steps: (A Selecting, by a selection unit, a sensing module corresponding to the maximum sensing data from the sensing data of the sensing modules; (B) using a compensation processing unit for each sensing of a statistical group The sensing data of the module determines an adjustment magnification, wherein the statistical group has the sensing module corresponding to the maximum sensing data and a plurality of sensing modules adjacent thereto, and the adjusting magnification is based on sensing data of each sensing module. Determined by the relative relationship between the sensing data of the proximity sensing module; and (C) using an arithmetic unit, using the setting position of the sensing module in the statistical group, corresponding sensing data, and adjusting magnification. Estimate the pressure position of the panel.

The reporting device of the present invention is applicable to a panel provided with a plurality of sensing modules, and each sensing module sends a sensing data due to the pressing of the panel. The reporting device includes: a selection unit, The sensing module of the sensing module selects a sensing module corresponding to the maximum sensing data; and a compensation processing unit determines an adjustment ratio for the sensing data of each sensing module of the statistical group, wherein The statistical group has the sensing module corresponding to the maximum sensing data and a plurality of sensing modules adjacent thereto, and the adjusting magnification is determined based on the relative relationship between the sensing data of each sensing module and the sensing data of the proximity sensing module. And an arithmetic unit, which uses the position of each sensor module in the statistical group, the corresponding sensing data, and the adjustment magnification to estimate the pressure position of the panel.

The above and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments.

Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to FIG. 1, a preferred embodiment of the reporting device of the present invention is applicable to a display system 100. The display system 100 includes a panel 1, a panel controller 2, and a processor 3. The panel controller 2 includes a receiving unit. 21 and the reporting device 20.

The panel 1 includes a base 11 , a plurality of inductors 12 and a frame plate 13 as shown in FIG. 2 , wherein the inductors 12 are disposed on the base 11 , and the frame plate 13 is superimposed on the inductors 12 to partially obscure Those sensors 12 on the side. Also, the panel 1 further includes a display surface 15 defined by the frame plate 13, and any position on the display surface 15 can be collectively represented using a target first axis element and a second axis element.

Preferably, the panel 1 is a capacitive touch panel comprising (M+1) sensing modules 17 and (N+1) sensing modules 18 as shown in FIG. The sensing modules 17 are disposed along the first direction X at a first axis element x _m = m × d, and the sensing modules 18 are disposed along the second direction Y at a second axis element y _n = n × d Where, m=0~M, n=0~N, d is the sensing module spacing, and d>0.

Each of the sensing modules 17 has a plurality of the inductors 12 arranged in the second direction Y. Each of the sensing modules 18 has a plurality of the inductors 12 arranged in the first direction X. And for ease of illustration, FIG. 3 is drawn with M=5 and N=4.

When the external force is applied to the display surface 15 of the panel 1, each of the sensing modules 17, 18 sends a sensing data representative of the sensing intensity to the receiving unit 21, so that the reporting device 20 calculates which label on the display surface 15 Selected. And the reporting device 20, when receiving a request for a request from the processor 3, provides the selected coordinate to the processor 3 for subsequent operations. Preferably, the sensing modules 17, 18 provide the frequency of the sensing data higher than the frequency of the selected coordinates, and the frequency of the selected coordinates is higher than the frequency of the reporting request.

Since the preferred embodiment of the reporting method performed by the reporting device 20 uses the same flow to calculate the first axis element and the second axis element of the selected coordinates, this article only describes the first axis element and assumes that the display The surface 15 can correspond to the first axis elements 0, 1, 2, 3, ... X, and the mth sensing module is disposed at the first axis element x _m = m × d, and X = x _M = M × d .

In general, the user presses the display surface 15 with a fingertip or a stylus, so that about 5 adjacent sensing modules 17 on the horizontal axis sense the pressure, and the sensing module 17 in the middle measures A larger value of the sensing data. However, if the pressing point is biased toward the side of the display surface 15, the sensing data of the side sensing module 17 may become smaller due to the shielding of the frame panel 13. Therefore, the reporting device 20 specially handles the coordinates when selecting the coordinates. Side sensing module 17.

In detail, the reporting device 20 includes a selection unit 22, a compensation processing unit 23, an arithmetic unit 25, a boundary processing unit 26, and a setting unit 27 as shown in FIG. The reporting method includes the following steps as shown in Figure 5:

Step 70: The setting unit 27 sets up to (2C+1) sensing modules 17 at most when calculating the selected coordinates. Preferably, this example sets C=2, but other values can be used.

Step 71: The selecting unit 22 selects, from the sensing data of the sensing modules 17, a Jth sensing module corresponding to the maximum sensing data, 0≦J≦M.

Step 72: The selection unit 22 judges J>C or J<(M-C). If yes, proceed to step 73; if no, the process jumps to step 81 to separately process the case where the reference sensing module 17 covers the side sensing module.

Step 73: When J>C or J<(MC), the selecting unit 22 selects the (JC)~(J-1) sensing modules as the first evaluation group, and selects the (J+1)~(J) +C) Sensor modules are used as the second evaluation group.

For convenience of description, the combination of the first evaluation group, the second evaluation group, and the Jth induction mode is hereinafter referred to as a "statistical group."

Step 74: The compensation processing unit 23 evaluates whether the relative relationship between the sensing data of the statistical group meets the preset requirement. If not, skip back to step 71 to receive the next batch of sensing data; if yes, proceed to step 75.

Referring to FIG. 6, the evaluation requirements of this step are two: first, whether the sensing data of the first evaluation group increases in sequence with the sensing module serial number; second, whether the sensing data of the second evaluation group follows the sensing module serial number. Decrease in sequence. That is to say, when the sensing data of the sensing module 17 in the statistical group becomes smaller as the distance between the sensing module 17 and the J sensor module is increased, step 75 is performed.

This is because when a plurality of adjacent sensing modules 17 on the horizontal axis feel pressure due to the fingertip or the stylus pressing the panel 1, the sensing data changes as described above. If the sensing data does not meet the foregoing, it is most likely caused by undesired interference behavior, so it is not included in the consideration jump back step 71 to capture the next batch of sensing data.

Step 75: The compensation processing unit 23 views each of the sensing data of the statistical group. If one of the sensing data values is less than a sensing threshold, the data is adjusted to 0; if not, the original data value is maintained. Because too small sensing data may be caused by external environmental interference, rather than touch operation behavior, this step discards too small sensing data.

Step 76: The compensation processing unit 23 determines an adjustment magnification R _m for each sensing data S _m of the statistical group.

Referring to Figure 7, ideally, the m-th sensing module sensing information S _m as a dotted line in the sensing distance linearly related presented triangular fold line, but actually quadratic curves similar to the solid line depicted. Such a quadratic curve may be partitioned into a nonlinear region satisfying S _m > 2 (S _{m -1} + S _{m +1} ), and a linear region not satisfying the inequality. It can be observed from the graph that only the linear region appears closer to the ideal triangular polyline. Therefore, this step is expected to give different adjustment magnifications R _m between the linear region and the nonlinear region to narrow the difference between the actual sensing data and the ideal value. Preferably, the adjustment magnification R _m has a value of 4/3 when S _m >2 (S _{m -1} +S _{m +1} ) is satisfied, and has a value of 1 when not satisfied, but is not limited thereto.

Step 77: Based on equation (1), the arithmetic unit 25 estimates which of the labels on the display surface 15 using the sensing data S _m of the sensing module 17 in the statistical group, the adjustment magnification R _{m ,} and the first axis element x _m . Clicked and then ends the process.

Wherein the adjusted sensor data S _m 'R _m using adjustment magnification adjusting the resulting sensor data S _m, this example embodiment is a _{S m' = R m ‧S m} . Furthermore, the formula (1) can also be rewritten into the formula (2), so another aspect can also be estimated by using the sensing module serial number m of the statistical group, the adjusted sensing data S _m ' and the sensing module spacing d. Click on the coordinates. Moreover, the formula (1) can be further rewritten into the formula (3), so an offset factor G can be used to adjust the first axis element J×d of the Jth sensing module, wherein G is based on the statistical number (mJ), After the adjustment, the sensing data S _m ' and the sensing module spacing d are obtained.

Specifically, the compensation processing unit 23 mainly uses the adjustment magnification R _m to adjust each sensing data S _{m of the} statistical group. For example, this example uses a larger adjustment magnification R _m to compensate for the non-sensitive distribution of the sensing data. Part of the linear region. However, in other embodiments, the sensing data segments may be distributed more segments, and the different sections in a different magnification adjustment to adjust the R _m. Moreover, these adjustment magnifications R _m need not be constant values, and may be a function related to the sensing data or the set position of the sensing module 17.

So far, the above is the reporting method performed by the sensing module 17 of the statistical group when it is not at the side. If the pressure of the display surface 15 is close to the side, the reporting method needs to be adjusted as follows.

Step 81: When 0≦J≦C, the boundary processing unit 26 selects the 0~(J-1) sensing modules as the first evaluation group, and selects the (J+1)~(J+C) sensing. The module is regarded as the second evaluation group; in addition, when (MC)≦J≦M, the (JC)~(J-1) sensing modules are selected as the first evaluation group, and the (J+1) is selected. ~M sensing modules are used as the second evaluation group.

Step 82: When 0≦J≦C, the boundary processing unit 26 multiplies the sensing data of the m=0th sensing module by a marginal magnification R _B ; when MC≦J≦M, the boundary processing unit 26 makes m== The sensing data of the M sensing modules is multiplied by the marginal magnification R _B .

Preferably, the marginal magnification R _B = 6/5 is used to compensate for the sensing capability of the side sensing module 17 which is partially blocked by the frame panel 13 .

Step 83: The boundary processing unit 26 determines whether J=0 is satisfied and the sensing data S ₁ ~S _{C of the} first to C sensing modules are both less than a critical value. If yes, proceed to step 84; if no, skip to step 85.

Step 84: The boundary processing unit 26 estimates the point selection coordinate to be 0xd, and returns to step 71 to process the next batch of sensing data.

Step 85: The boundary processing unit 26 determines whether J=M is satisfied and the sensing data S _MC ~S _{M-1 of} the (MC)~(M-1) sensing modules are both smaller than the critical value. If yes, go to step 86; if no, execute steps 74-77 to calculate the click coordinates based on one of equations (1) to (3).

Step 86: The boundary processing unit 26 estimates the click coordinates as M x d and returns to step 71.

It should be noted that in another implementation manner, steps 82-86 may also be performed first, and then step 81 is performed to define the first evaluation group and the second evaluation group. Also, steps 83, 85 can be performed simultaneously, or the order of execution can be exchanged.

It is also worth noting that the reporting method of the present embodiment is applicable to a variety of other types of panels, such as a resistive touch panel, an optical touch panel, and an acoustic wave touch panel, in addition to a capacitive touch panel. Or electromagnetic touch panel...etc.

Simulation result

In the case where the robot arm slides straight through the display surface 15 in a diagonally diagonal manner on the upper left and the lower right, the point coordinates obtained by the conventional linear estimation are collected together to obtain the point calculated in the present embodiment. Selecting the coordinates together will result in Figure 9. Comparing the two phases, the result of this example is closer to the diagonal line of the upper left and lower right.

In addition, in the case where the robot arm slides straight along the right side of the display surface 15, the point coordinates obtained by the conventional linear estimation are collected together to obtain FIG. 10, and the point selection coordinates calculated in this embodiment are collected. Together, we will get Figure 11. Comparing the two phases, the results of this example are clearly approximate to the straight line.

Moreover, if the sensing capability of a certain sensing module 17 of the panel 1 is weak and the measured data is always low, the computing unit 25 can also increase the sensing according to a pre-magnification before step 70. Sensing data of the module 17. Therefore, the sensing data adjusted by the arithmetic unit 25 at the end of step 77 has the effect of the previous magnification in the linear region, and the effect of the pre-magnification and the adjustment magnification R _m in the nonlinear region.

For example, the mechanical arm slides through the display surface 15 at a constant speed from left to right with a fixed force, so that the adjacent two sensing modules 17 sense the sensing data as shown by the solid line and the broken line in FIG. 12 for a period of time. Further, the point selection coordinates are as shown in the solid line of FIG. However, under the premise of fixing the force, ideally, the two sensing modules 17 should have similar sensing data values, so this example is specifically for the left module 17 corresponding to the solid line and the sensing capability is slightly weak. And adjust the magnification R _m to pull up the sensed data value as shown by the dotted line in Fig. 12, and then obtain the compensated clicked coordinates as shown by the dotted line in Fig. 13. Obviously, in Figure 13, the compensated dotted line coordinates are more to the left (i.e., corresponding to the smaller first axis element) than the solid line coordinates before compensation.

In summary, in the foregoing preferred embodiment, the reporting device 20 adjusts the sensing data in the non-linear region with the adjustment magnification R _m , and adjusts the sensing of the side sensing modules 17 and 18 with the marginal magnification R _B . With the information, it is possible to more accurately locate which one of the display faces 15 is selected, so that the object of the present invention can be achieved.

The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
