Abstract
The invention relates to a method for debugging the sensitivity of a touch panel in a device. In the method, a touch panel and an FPC (Flexible Printed Circuit) connected with the touch panel are utilized to adjust the sensitivity of the touch panel through respectively calculating the variations of capacitance in the presence or absence of an external device. The method provided by the invention is simple and can be used for rapidly finding out the capacitance needing to be adjusted, so that the touch panel is mutually matched with the capacitance of the external device, thereby finally achieving the purpose of ensuring the sensitivity for the touch panel.
Description
Technical field
The present invention relates to a kind of debugging contact panel sensitivity of method, refer in particular to debugging contact panel sensitivity of method under the condition of external equipment.
Background technology
Continuous development along with touch technology, contact panel has replaced traditional press button mechanism, because its proportion of goods damageds are little, advantages such as the easy to use and life-span is long, more and more be applied in the various fields at present, as the touch controlled handset that occurs on the market, computer etc., and contact panel also has been penetrated into household electrical appliances, automobile and other industries gradually recently, so following touch technology will become an indispensable part in people's life.
Present stage, after contact panel and chip production go out, at first need to debug the request for utilization that arrives the user up to the sensitivity of contact panel, and then it is assembled in the external mechanism.And in the practical application of capacitance touching control chip; we can run into such situation usually; same chip is different fully with the effect that contact panel obtains in different mechanisms; after will debugging good contact panel and be installed in the mechanism of certain external hardware such as the slip-stick artist; the sensitivity meeting of contact panel at this moment is subjected to the influence of this environment; sensitivity may slightly change, and the sensitivity meeting reduces generally speaking, but this reduction may can't influence the use of contact panel.But more common situation is a contact panel be installed to some external units after, the sensitivity meeting declines to a great extent, the user can not normally use when serious.The slip-stick artist just must debug to the environment that can adapt to contact panel under this hardware device like this.And cause an otherness that main cause is exactly an external device of The above results, thus if we can measure the reference capacitance value in the distinct device, just can it be compensated and adjust, thus can deal with problems fast.
Therefore need solve above problem for users provide a kind of easier method.
Summary of the invention
The actual technical matters to be solved of the present invention is how to provide a kind of under the condition of external equipment, debugging contact panel sensitivity of method.
In order to realize above-mentioned purpose of the present invention, the invention provides contact panel sensitivity of method in a kind of commissioning device, it comprises contact panel and the FPC that is connected with contact panel, and step is as follows: at first calculate in the electric capacity that does not have described contact panel under the condition of external equipment; Calculate the electric capacity of described contact panel under the condition of external equipment then; At last, thus external equipment is compensated purpose that arrive to adjust contact panel sensitivity according to the two electric capacity difference.
Debugging contact panel sensitivity of method of the present invention, the method of having utilized the RC oscillatory circuit to measure the external equipment electric capacity is finally debugged out its suitable sensitivity, not only simple, and can find out the electric capacity that needs adjustment fast, the electric capacity of contact panel and external equipment is mated mutually, the final purpose that guarantees contact panel sensitivity that arrives.
Description of drawings
Fig. 1 is the circuit diagram of debugging contact panel of the present invention sensitivity;
The waveform synoptic diagram of two kinds of frequencies when Fig. 2 is a debugging contact panel of the present invention.
Embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
Contact panel sensitivity of method in the commissioning device of the present invention, the FPC that comprises contact panel and be connected (flexible circuit board) with contact panel, described equipment is meant external equipment, as mobile phone, main bodys such as computer, the contact panel of the above-mentioned FPC of having need be installed on the external equipment.
The sensitivity of contact panel when being installed on the external equipment for the contact panel that guarantees the above-mentioned FPC of having, we are provided with a RC oscillatory circuit on FPC, and its circuit diagram please refer to shown in Figure 1, and wherein R, Rf, R1 represent resistance, and C represents electric capacity,
Represent transport and placing device, and Rf and R1 be the resistance that is complementary with transport and placing device, resistance R and capacitor C are formed the RC oscillatory circuit, and Uf represents the magnitude of voltage of RC oscillatory circuit, and Uo represents the total voltage of entire circuit.
The contact panel of the above-mentioned FPC of having is under the situation that does not connect external equipment, because this moment, the frequency F1 of contact panel can draw by the oscillograph detecting, please refer to the dotted line described in Fig. 2, and the numerical value of resistance R is fixed, so, just can calculate the capacitor C 1 of this moment according to the formula F 1=1/2* л * R*C1 of frequency and electric capacity; Continue the above-mentioned numerical value that has contact panel frequency F2 of described contact panel under the situation that connects external equipment of FPC of detecting, this frequency F2 still can measure by oscillograph, please refer to the solid line described in Fig. 2, utilize formula F 2=1/2* л * R*C2 to calculate the numerical value of capacitor C 2 again; Difference according to above-mentioned C1 and C2 just can compensate the electric capacity of the said equipment and adjust, to reach the purpose of the described contact panel sensitivity of debugging.
Contact panel sensitivity of method in the commissioning device of the present invention, utilized the RC oscillatory circuit finally to judge the changing value of described contact panel electric capacity under the environment of external device, according to the final sensitivity of effectively adjusting contact panel of above-mentioned changing value.
