Referring to fig. 2, fig. 2 is a schematic flow chart of a capacitive touch error correction method according to an embodiment of the present invention;
as shown in fig. 2, the method includes steps S201 to S203.
S201, detecting the circuit of the capacitive touch frame, finding out the circuit with the disconnection phenomenon, and marking the circuit as a target circuit.
In this embodiment, as shown in fig. 1, in each line of the capacitive touch frame, a longitudinal TX (longitudinal transmitting electrode) sends out an excitation signal, a transverse RX (transverse receiving electrode) receives the excitation signal, calculating and obtaining the capacitance value of the intersection point of each longitudinal TX and the corresponding transverse RX, and judging whether the line of the capacitive touch frame is normal according to the obtained capacitance value, if the capacitance value of a certain line is detected to be too small, the reason may be that the longitudinal TX of the line has a disconnection phenomenon, the disconnection phenomenon means that the longitudinal TX of the line cannot emit an excitation signal or the emitted excitation signal is weak, resulting in a weak signal received by the lateral RX, which in turn results in too small a capacitance value for the line, namely, the line is broken, and the broken line is marked as a target line so as to repair the target line in the following process. Of course, the lateral TX may send out an excitation signal, and the longitudinal RX may receive the excitation signal, so as to implement the capacitive touch error correction in this scenario as well.
In one embodiment, as shown in fig. 3, the step S201 includes:
s301, detecting all lines of the capacitive touch frame by using a fixed voltage through a capacitive driving circuit to obtain a capacitance value of each line;
s302, comparing the capacitance value of each line with a first preset threshold value, determining the line which does not exceed the first preset threshold value as a line with a disconnection phenomenon, and marking the line as a target line.
In this embodiment, a capacitor driving circuit detects all lines of the capacitor touch frame by using a fixed voltage such as 12V, and obtains a capacitance value of each line; and comparing the capacitance value of each line with a first preset threshold value, wherein the first preset threshold value is used for judging whether the line is broken, if the capacitance value of the line does not exceed the first preset threshold value, the capacitance value of the line is too small, the line is judged to be broken and marked as a target line, and the line between Xn and Xn +1 in fig. 1 is the marked target line.
In one embodiment, the step S301 includes:
and automatically triggering and detecting all lines of the capacitive touch frame according to the set time interval and obtaining the capacitance value of each line.
In this embodiment, by setting the time interval, after each time interval, all the lines of the capacitive touch frame are automatically triggered and detected, and the capacitance value of each line is obtained, so as to monitor whether a line break occurs in the capacitive touch frame in real time, and mark a target line that appears in a short time for repair.
Furthermore, the capacitance values of all lines detected each time can be analyzed to obtain the variation of each line at different time intervals, so as to predict the lines with possible broken lines.
In an embodiment, the step S201 further includes:
and shielding the driving channel of the target line.
In the embodiment, after the line with the disconnection phenomenon is found and marked as the target line, the driving channel of the target line is shielded, and the target line does not emit the excitation signal any more after shielding, so that the excitation time of the target line can be directly skipped when the line of the whole capacitive touch frame is detected, and the detection time is saved.
S202, acquiring a reference mean value of the capacitive touch frame, and taking the reference mean value as a capacitive reference value of a target value.
In this embodiment, the reference mean value of the capacitive touch frame is a value that each normal line can reach or approach, and the target value is a capacitance value that the target line should have, so that the reference mean value can be used as a capacitance reference value of the target value, that is, the value of the capacitance value of the target line that is restored to the reference mean value is the repair standard of the target line.
In an embodiment, as shown in fig. 4, the step S202 includes:
s401, after detecting and confirming that all lines of the capacitive touch frame are not abnormal, acquiring capacitance values of all lines of the capacitive touch frame in a non-touch state, and taking an average value of the capacitance values of all lines as a reference mean value of the capacitive touch frame;
and S402, taking the reference mean value as a capacitance reference value of the target value.
In this embodiment, based on the condition that all lines of the capacitive touch frame are not abnormal, capacitance values of all lines of the capacitive touch frame in a non-touch state are detected and obtained, where the obtained capacitance value of each line has a certain difference, the capacitance value of each line belongs to a normal value in a certain range, an average value of the capacitance values of all lines is used as a reference average value of the capacitive touch frame, and the obtained reference average value is a value that can be reached or approximate to each normal line; that is, the capacitance value of the target line should also reach or approach the baseline average value; the reference mean value is taken as the capacitance reference value of the target value.
And S203, marking a front line and a rear line adjacent to the target line, and adjusting the driving power of the front line and the rear line to increase the capacitance value of the broken line area of the target line and reach a target value.
In this embodiment, in the front line and the rear line adjacent to the target line, the front line is on one side of the target line, and the rear line is on the other side of the target line, by adjusting the driving power of the front line and the rear line, the excitation signal of the front line can be diffused to one side of the disconnection area of the target line, and the excitation signal of the rear line can be diffused to the other side of the disconnection area of the target line, so as to fill up the excitation signal of the disconnection area of the target line, that is, the capacitance value of the disconnection area is increased and reaches the target value; and repairing the target circuit from the beginning to complete the touch function.
In one embodiment, as shown in fig. 5, the step S203 includes:
s501, marking a front line and a rear line adjacent to the target line;
s502, simultaneously increasing the driving power of the front line and the rear line so as to enable the excitation signals of the front line and the rear line to be diffused to the disconnection area of the target line;
s503, calculating the capacitance average value of the excitation signal of the front line and the excitation signal of the rear line received by the disconnection area, and taking the capacitance average value as the capacitance value of the target line;
and S504, continuously increasing the driving power of the front line and the rear line until the capacitance value of the target line reaches a target value.
In this embodiment, in the capacitive touch frame, each longitudinal TX corresponds to one transverse RX, so as to form an intersection point and serve as a capacitance value of one line, however, in an excitation signal received by one transverse RX, in addition to the excitation signal from the corresponding longitudinal TX, an excitation signal from an adjacent line of the corresponding longitudinal TX is also present, that is, the disconnection area of the target line may receive an excitation signal spread by a neighboring line; based on the phenomenon, the excitation signals of the front line and the rear line adjacent to the target line are increased, that is, the excitation signals of the front line and the rear line can be filled in the disconnection area of the target line in a diffusion mode, so that the capacitance value of the target line reaches the target value.
Specifically, the front line and the rear line adjacent to the target line are marked, such as Xn and Xn +1 in fig. 1, and the driving power of the front line and the rear line is increased at the same time, so that the excitation signals of the front line and the rear line are increased, and the excitation signal diffused to the target line is increased, so that the excitation signal of the adjacent line received by the broken line area of the target line is increased, and the purpose of filling the capacitance of the broken line area of the target line is achieved.
In the process of increasing the driving power of the front line and the rear line, synchronously calculating the capacitance average value of the excitation signal of the front line and the excitation signal of the rear line received by the disconnection area, and taking the capacitance average value as the capacitance value of the target line; when the capacitance value of the target line increases and reaches or approaches the target value, the increase of the driving power of the front line and the rear line may be stopped.
It should be noted that, in the embodiment of the present invention, the line break phenomenon and the repair process are described by using that the longitudinal TX fails to transmit the excitation signal or the transmitted excitation signal is weak, it can be understood that, if the received excitation signal is weak due to the failure of the lateral RX, which also causes the line break phenomenon, the excitation signal of the corresponding longitudinal TX may be directly strengthened, and if the corresponding longitudinal TX is not enough to be repaired, the repair may be implemented by increasing the driving power of the adjacent line in the same manner as described above.
In an embodiment, the method further comprises:
and aiming at the target line, reducing a second preset threshold value for judging whether the target line is in a touch state.
In this embodiment, since the target line is a broken line, although the capacitance of the target line is filled by adjusting the driving power of the adjacent line of the target line, the driving power of the adjacent line of the target line has an upper limit, and the second preset threshold for determining whether the target line is in a touch state can be appropriately lowered while increasing the driving power of the adjacent line of the target line, thereby improving the stability of the touch sensing of the target line.
The embodiment of the invention also provides a capacitive touch error correction device, which is used for executing any embodiment of the capacitive touch error correction method. Specifically, referring to fig. 6, fig. 6 is a schematic block diagram of a capacitive touch error correction device according to an embodiment of the present invention.
