Embodiment
For making there is further understanding to object of the present invention, structure, feature and function thereof, embodiment is hereby coordinated to be described in detail as follows.
Calibration schematic diagram of the present invention as shown in Figure 1, calibrating installation 1 has processor 10, and contact panel 2 has touch-control integration module 20, and contact panel 2 is capacitance type touch-control panel, but is not limited thereto.As shown in Figure 2, Fig. 2 is the display schematic diagram of the primary calibration numerical value of each position of contact panel of one embodiment of the invention, in the present embodiment, contact panel 2 is on average divided into 16 positions, and each position all represents its relative position on panel by coordinate.The quantity of the position of contact panel 2 is decided by the size of contact panel 2 and divided number of times, and contact panel 2 is larger, and divided number of times is more, then the number of positions of contact panel 2 is more.Contact panel 2 and calibrating installation 1 are electrically connected, touch-control integration module 20 detects the external environment of each position of contact panel 2, obtain the primary calibration numerical value representing each position external environment information, primary calibration numerical value is the charge value of each position of the contact panel 2 sensed by touch-control integration module 20, if primary calibration numerical value be on the occasion of, then illustrate that the electric charge that touch-control integration module 20 senses is positive charge, if primary calibration numerical value is negative value, then illustrate that the electric charge that touch-control integration module 20 senses is negative charge, if primary calibration numerical value is 0, then this position of contact panel 2 is disturbed without electric charge, if the absolute value of the primary calibration numerical value of a certain position of contact panel 2 is larger, then the amount of charge of this position is more.According to the primary calibration numerical value obtained, processor 10 judges whether each position exists external environmental interference, and then determine that contact panel 2 is the need of calibration.
Please refer to Fig. 3, Fig. 3 is the process flow diagram of an embodiment of calibration steps of the present invention.Specifically, the calibration steps of contact panel 2 of the present invention comprises the following steps:
101: processor 10 sends the instruction of the primary calibration numerical value of detecting each position of contact panel 2 to touch-control integration module 20;
102: touch-control integration module 20 receives this instruction;
103: touch-control integration module 20 detects the primary calibration numerical value of each position of contact panel 2, this primary calibration numerical value represents the external environment of a position of this contact panel;
Detected by the environment of each position of touch-control integration module 20 pairs of contact panels 2, and obtain the primary calibration numerical value of each position external environment information of representative contact panel 2 as shown in figures 2 or 4, all primary calibration numerical value forms the set of primary calibration numerical value, wherein, Fig. 4 is another display schematic diagram of the primary calibration numerical value of each position of contact panel of one embodiment of the invention.
104: the primary calibration numerical value of above-mentioned each position of contact panel 2 detected is returned to processor 10 by touch-control integration module 20;
105: processor 10 judges that the primary calibration numerical value of each position is whether in preset range, if this primary calibration numerical value is not in this preset range, then re-executes step 101;
106: if this primary calibration numerical value is in this preset range, the primary calibration numerical value storing each position in touch-control integration module 20, in order to calibrate this contact panel.In other embodiment, the primary calibration numerical value of each position also can be stored in other memory storage, and this memory storage can be arranged at calibrating installation, can also be an independently memory storage, can read the information stored for processor 10.
Ideally, the primary calibration numerical value of each position is 0, namely there is not the interference of external environment, but be difficult to accomplish noiseless under the production environment of reality, thus the primary calibration numerical value of each position has different numerical value because of the difference of the external environment of this position, and the absolute value larger explanation external interference of numerical value is larger; For different contact panels, the external interference degree that it can bear is also different, and the first meeting of therefore design gives different contact panels different primary calibration numerical value preset range.
As shown in Figure 4, the preset range of the primary calibration numerical value of contact panel 2 is [-80,80], in Fig. 4, the primary calibration numerical value of position (X1, Y3) is-112, exceed preset range, then primary calibration failure, checks and removes the disturbing factor (as electrostatic etc.) of contact panel 2 position (X1, Y3), and again sent the instruction of the primary calibration numerical value of detecting each position of contact panel 2 by processor 10, i.e. repeated execution of steps 101-105; And the primary calibration numerical value of each position shown in Fig. 2 is all in this preset range [-80,80], then the primary calibration numerical value of touch-control integration module 20 to each position stores, and processor 10 judges primary calibration success, and terminates calibration.
As shown in Figure 5, be the process flow diagram of another embodiment of calibration steps of the present invention.Below be described in detail.In the step 105 of above-described embodiment, when processor 10 judges that the primary calibration numerical value of each position is in preset range, calibration steps of the present invention is further comprising the steps of:
107: processor 10 sends the instruction of the secondary calibration numerical value of detecting each position of contact panel 2 to touch-control integration module 20;
108: touch-control integration module 20 receives this instruction;
109: touch-control integration module 20 detects the secondary calibration numerical value of each position of contact panel 2;
Touch-control integration module 20 detects one group of secondary calibration numerical value (i.e. the set of secondary calibration numerical value), and secondary calibration numerical value is identical with primary calibration numerical value meaning, is all the charge value of each position of contact panel 2 that touch-control integration module 20 senses.Because the time of detecting is different, the external environment of contact panel 2 may change thereupon, therefore, the secondary calibration numerical value of each position now detected also may be not quite similar with the above-mentioned primary calibration numerical value detected, as shown in Figures 6 and 7, Fig. 6 and Fig. 7 is two display schematic diagram of the secondary calibration numerical value of each position of contact panel of another embodiment of the present invention.Because aforementioned 101-106 did primary calibration to contact panel 2, so the secondary calibration numerical value of each position of the contact panel 2 shown in Fig. 6 and Fig. 7 is all in preset range [-80,80].
110: touch-control integration module 20 returns the secondary calibration numerical value of detecting to processor 10;
111: processor 10 calculates the real time value of each position;
Real time value is the difference of the absolute value of each position secondary calibration numerical value and the absolute value of correspondence position primary calibration numerical value, real time value is abnormal excessive or too small, also easily cause misoperation, therefore, carry out the size of real time value correcting the generation that further can reduce misoperation.As shown in Fig. 2 and Fig. 6, Fig. 2 is the primary calibration numerical value that primary calibration is successfully stored in each position of contact panel 2 in touch-control integration module 20, Fig. 6 is the secondary calibration numerical value of each position of contact panel 2, the absolute value of the secondary calibration numerical value of each position and the absolute value of correspondence position primary calibration numerical value subtract each other the real time value namely obtaining each position, finally obtain the display schematic diagram of the real time value of each position of contact panel 2 as shown in Figure 8; In like manner, by secondary calibration numerical value and the primary calibration numerical value of each position shown in Fig. 7 and Fig. 2, another display schematic diagram of the real time value of each position of contact panel 2 as shown in Figure 9 can be obtained.
112: judge whether the absolute value of this real time value is less than or equal to preset difference value, if the absolute value of this real time value is greater than this preset difference value, then re-executes step 107;
113: if the absolute value of this real time value is less than or equal to this preset difference value, then calibrate end.
Ideally, the real time value of each position also should be 0, but actual state is difficult to reach noiseless, therefore, also gives different contact panel different preset difference values, limit the maximum external interference that contact panel can bear at the beginning of design.In the present embodiment, the preset difference value of contact panel 2 is set to 20, if the secondary calibration numerical value of each position of contact panel 2 as shown in Figure 7, then the real time value of its correspondence namely as shown in Figure 9, position (X1 in Fig. 9, the absolute value of real time value Y3) is 31, be greater than preset difference value 20, therefore, namely processor 10 judges secondary calibration failure, check and remove contact panel 2 position (X1, Y3) disturbing factor (as electrostatic etc.), and the instruction of the secondary calibration numerical value of detecting each position of contact panel 2 is again sent to touch-control integration module 20, namely step 107 is re-executed.If the secondary calibration numerical value of each position of contact panel 2 as shown in Figure 6, then the real time value of its correspondence namely as shown in Figure 8, in Fig. 8, the absolute value of the real time value of each position is all less than (or equaling) preset difference value 20, so namely processor 10 judges secondary calibration success, and terminates calibration.
In sum, contact panel calibration steps provided by the invention is by judging whether excessive or too small to the calibration figure of record environmental information, thus judge whether to there is external interference, and carry out once with secondary calibration, make the calibration steps of contact panel more reliable and have more practicality.
The present invention is described by above-mentioned related embodiment, but above-described embodiment is only enforcement example of the present invention.Must it is noted that the embodiment disclosed limit the scope of the invention.On the contrary, change done without departing from the spirit and scope of the present invention and retouching, all belong to scope of patent protection of the present invention.
