That is, these functional entities may be implemented in the form of software, or in one or more software-hardened modules, or in different networks and/or processor devices and/or microcontroller devices.

First, as shown in fig. 1 and 4, the touch assembly may include a touch layer 100 and a plurality of first reading modules 21, wherein the touch layer includes a first touch area 01 and a second touch area 02, the first touch area 01 is distributed with a plurality of first touch units 11, the second touch area 02 is distributed with a plurality of second touch units 12, the second touch units 12 generate a first touch signal when being triggered, the second touch units 12 generate a second touch signal when being triggered, and the first touch signal is different from the second touch signal; each first reading module 21 is correspondingly connected to a first touch unit 11, the first reading module 21 receives a first touch signal, a first reference signal and a second reference signal, respectively, and the first reading module 21 converts the first touch signal into the second touch signal in response to the first touch signal, the first reference signal and the second reference signal.

The touch control assembly provided by the embodiment of the disclosure receives the first touch control signal, the first reference signal and the second reference signal through the first reading module 21, and converts the first touch control signal into the second touch control signal in response to the first touch control signal, the first reference signal and the second reference signal, so that the touch control signals output by the first touch control area 01 and the second touch control area 02 are consistent, and the problem that the touch control signals output by the electronic equipment are inconsistent due to different shapes of the touch control electrodes can be solved, thereby affecting the touch control signals of the electronic equipment, further allowing the touch control electrodes to have special-shaped areas such as an opening area, allowing part of the touch control electrodes to be removed in a corresponding area (the first touch control area 01) of the camera under the screen, avoiding the influence of diffraction of a touch control layer on the imaging quality of the camera under the screen, and improving the imaging quality of the camera under the screen.

Further, the touch device provided by the embodiment of the present disclosure may further include a plurality of second reading modules 22, each second reading module 22 is correspondingly connected to a second touch unit 12, and the second touch unit 12 is configured to read and output a second touch signal.

The first touch area 01 may be a touch area corresponding to the camera module under the screen, and the second touch area 02 may be a normal touch area. The effective areas and shapes of the touch electrodes of the first touch unit 11 and the second touch unit 12 are different. Since the effective areas and shapes of the touch electrodes of the first touch unit 11 and the second touch unit 12 are different, when the first touch unit 11 and the second touch unit 12 receive touch operations, the touch signals generated by the two touch units are also different. For example, the voltages of the first touch signal and the second touch signal are different, or the currents and the voltages of the first touch signal and the second touch signal are different.

The first reading module 21 provided in the embodiment of the present disclosure is configured to read a touch signal of a first touch area 01 (a special-shaped touch area) of an electronic device. As shown in fig. 3, the electronic device at least includes a first touch area 01 (a special-shaped touch area) and a second touch area 02 (a standard touch area), the second touch area 02 has a plurality of regular standard touch units, the regular touch units generate a second touch signal when touched by a user, and the second touch signal is output by the second reading module 22.

Since the area and shape of the first touch unit 11 are different from those of the second touch unit 12, when the user touches the first touch unit 11, a signal generated by the first touch unit 11 in response to the touch action is the first touch signal Vin. The voltage of the first touch signal Vin is different from the voltage of the second touch signal Vin.

It should be noted that, in the embodiment of the disclosure, the voltage (or the current) of the second touch signal may be a voltage range, that is, the voltage (or the current) of the second touch signal is within a preset threshold range. When the voltage (or current) of the first touch signal is within the threshold range, the first touch signal and the second touch signal are considered to be consistent, and when the voltage (or current) of the first touch signal is outside the threshold range, the first touch signal and the second touch signal are considered to be inconsistent.

As shown in fig. 2, the first reading module 21 may include: the touch control circuit comprises a first comparing unit 110, a second comparing unit 120 and an and gate unit 130, wherein an inverting terminal of the first comparing unit 110 receives a first touch signal Vin, a common terminal of the first comparing unit 110 receives a first reference signal Vref1, a voltage of the first reference signal Vref1 is greater than a voltage of the first touch signal Vin, and the first comparing unit 110 is configured to output a first signal in response to the first touch signal Vin; the inverting terminal of the second comparing unit 120 receives the second reference signal Vref2, the homonymous terminal of the second comparing unit 120 receives the first touch signal Vin, the voltage of the second reference signal Vref2 is less than the voltage of the first touch signal Vin, and the second comparing unit 120 is configured to output a second intermediate signal in response to the first touch signal Vin; a first input terminal of the and unit 130 is connected to the output terminal of the first comparing unit 110, a second input terminal of the and unit 130 is connected to the output terminal of the second comparing unit 120, and the and unit 130 is configured to output a second touch signal according to the first intermediate signal and the second intermediate signal.

In the first read module 21 provided by the present disclosure, the first comparison unit 110 converts the first touch signal Vin smaller than the voltage of the first reference signal Vref1 into the touch output signal, and the second comparison unit 120 converts the first touch signal Vin larger than the voltage of the second reference signal Vref2 into the touch output signal, that is, when the first touch signal Vin is located in the interval from the second reference signal Vref2 to the first reference signal Vref1, the voltage of the output signals is guaranteed to be consistent by the first read module 21. The problem that the touch electrode is different in shape and first touch signals Vin are inconsistent can be solved, so that touch signals of electronic equipment are affected, the touch electrode is allowed to have special-shaped areas such as an open area, a touch layer is allowed to be removed from a corresponding area of the camera under the screen, the influence of diffraction of the touch layer on the imaging quality of the camera under the screen is avoided, and the imaging quality of the camera under the screen is improved.

Further, as shown in fig. 3, the first reading module 21 provided in the embodiment of the present disclosure may further include a reference signal unit 310, where the reference signal unit 310 is respectively connected to the first comparing unit 110 and the second comparing unit 120, and the reference signal unit 310 is configured to output a first reference signal Vref1 and a second reference signal Vref 2.

The reference signal unit 310 can provide the first reference signal Vref1 to the first comparing unit 110 and the second reference signal Vref2 to the second comparing unit 120, so that the first comparing unit 110 generates a touch output signal in response to the first touch signal Vin according to the first reference signal Vref1, and the second comparing unit 120 generates a touch output signal in response to the first touch signal Vin according to the second reference signal Vref 2.

As shown in fig. 5, the first comparing unit 110 includes a first voltage comparator 111, an inverting terminal of the first voltage comparator 111 receives the first touch signal Vin, a common terminal of the first voltage comparator 111 receives a first reference signal Vref1, and a voltage of the first reference signal Vref1 is greater than a voltage of the first touch signal Vin. The first voltage comparator 111 outputs a first intermediate signal in response to the first touch signal Vin, the first intermediate signal may be a high level signal, and the voltage of the first intermediate signal may be identical to a standard touch signal output by a standard touch unit.

The second comparing unit 120 includes a second voltage comparator 121, a common terminal of the second voltage comparator 121 receives the first touch signal Vin, an opposite terminal of the second voltage comparator 121 receives a second reference signal Vref2, and a voltage of the second reference signal Vref2 is less than a voltage of the first touch signal Vin. The second voltage comparator 121 outputs a second intermediate signal in response to the first touch signal Vin, the second intermediate signal may be a high level signal, and the voltage of the second intermediate signal may be identical to a standard touch signal output by a standard touch unit.

In a possible embodiment of the present disclosure, the and gate unit 130 includes an and gate 131, a first input terminal of the and gate 131 is connected to the output terminal of the first comparing unit 110, and a second input terminal of the and gate 131 is connected to the output terminal of the second comparing unit 120. The touch output signals output by the first voltage comparator 111 and the second voltage comparator 121 are both high level signals, so the output end of the and gate also outputs a high level signal.

Wherein, when the first voltage comparator 111 and the second voltage comparator 121 both output a high level signal, the and gate 131 outputs a high level signal. The and gate 131 outputs a low level signal when one or both of the first voltage comparator 111 and the second voltage comparator 121 output a low level signal.

The inverting terminal of the first voltage comparator 111 receives the first touch signal Vin, the inverting terminal of the first voltage comparator 111 receives the first reference signal Vref1, and the voltage of the first reference signal Vref1 is greater than the voltage of the first touch signal Vin. That is, the voltage of the first voltage comparator 111 at the same end is greater than the voltage of the opposite end, and the first voltage comparator 111 outputs a high level signal. The common terminal of the second voltage comparator 121 receives the first touch signal Vin, the inverting terminal of the second voltage comparator 121 receives the second reference signal Vref2, and the voltage of the second reference signal Vref2 is smaller than the voltage of the first touch signal Vin. That is, the voltage of the same terminal of the second voltage comparator 121 is greater than the voltage of the opposite terminal, and the second voltage comparator 121 outputs a high level signal. When the voltage of the first touch signal Vin is between the voltage of the second reference signal Vref2 and the voltage of the first reference signal Vref1, the and gate outputs a high level signal.

In practical applications, the upper limit value and the lower limit value of the first touch signal Vin may be detected, the upper limit value of the first touch signal Vin is used as the first reference signal Vref1, and the lower limit value of the first touch signal Vin is used as the second reference signal Vref 2.

For example, when Vin < Vref2 < Vref1, Vout1 is VH, Vout2 is VL, and VL is VL after passing through the and gate;

when Vref2 < Vin < Vref1, Vout1 is VH, Vout2 is VH, and VH is obtained after passing through AND gate;

when Vref2 < Vref1 < Vin, Vout1 is VL, Vout2 is VH, and VL is obtained after passing through an AND gate;

wherein Vin is a first touch signal Vin, Vref1 is a first reference signal Vref1, Vref2 is a second reference signal Vref2, Vout1 is a first intermediate signal, Vout2 is a second intermediate signal, VH is a high level signal, and VL is a low level signal. Therefore, the first touch module provided by the embodiment of the disclosure can read the touch signal when Vref2 < Vin < Vref1, and the reading range is wide.

In another possible embodiment of the present disclosure, as shown in fig. 6, the and gate unit 130 may include a nand gate 132 and an inverter 133, a first input of the nand gate 132 is connected to the output of the first comparing unit 110, and a second input of the nand gate 132 is connected to the output of the second comparing unit 120; the input of inverter 133 is connected to the output of nand gate 132.

When the first voltage comparator 111 and the second voltage comparator 121 both output a high level signal, the nand gate 132 outputs a low level signal, and the low level signal is converted into a high level signal through the inverter 133. When one or both of the first voltage comparator 111 and the second voltage comparator 121 output a low level signal, the nand gate 132 outputs a high level signal, which is converted into a low level signal through the inverter 133.

The inverting terminal of the first voltage comparator 111 receives the first touch signal Vin, the inverting terminal of the first voltage comparator 111 receives the first reference signal Vref1, and the voltage of the first reference signal Vref1 is greater than the voltage of the first touch signal Vin. That is, the voltage of the first voltage comparator 111 at the same end is greater than the voltage of the opposite end, and the first voltage comparator 111 outputs a high level signal. The common terminal of the second voltage comparator 121 receives the first touch signal Vin, the inverting terminal of the second voltage comparator 121 receives the second reference signal Vref2, and the voltage of the second reference signal Vref2 is smaller than the voltage of the first touch signal Vin. That is, the voltage of the same terminal of the second voltage comparator 121 is greater than the voltage of the opposite terminal, and the second voltage comparator 121 outputs a high level signal. When the voltage of the first touch signal Vin is between the voltage of the second reference signal Vref2 and the voltage of the first reference signal Vref1, the nand gate 132 outputs a low level signal, and the low level signal is converted into a high level signal after passing through the inverter 133.

For example, when Vin < Vref2 < Vref1, Vout1 is VH, Vout2 is VL, and VL is obtained after passing through nand gate 132 and inverter 133;

when Vref2 < Vin < Vref1, Vout1 is VH, Vout2 is VH, and VH is obtained after passing through nand gate 132 and inverter 133;

when Vref2 < Vref1 < Vin, Vout1 is VL, Vout2 is VH, and VL is obtained after passing through nand gate 132 and inverter 133;

wherein Vin is a first touch signal Vin, Vref1 is a first reference signal Vref1, Vref2 is a second reference signal Vref2, Vout1 is a first intermediate signal, Vout2 is a second intermediate signal, VH is a high level signal, and VL is a low level signal. Therefore, the first reading module 21 provided by the embodiment of the disclosure can read the touch signal when Vref2 < Vin < Vref1, and the reading range is wide.

A second terminal of the second resistor R2 may be connected to ground.

On this basis, the voltage of the first reference signal Vref1 is as follows:
