In this embodiment, each of the units AU1 to AU4 includes an electronic component and a test circuit. Taking this embodiment as an example, the unit AU1 (first unit) includes an electronic component AE1 (first electronic component) and a test circuit TC1. The unit AU2 includes an electronic component AE2 and a test circuit TC2. The unit AU3 includes an electronic component AE3 and a test circuit TC3. The unit AU4 includes an electronic component AE4 and a test circuit TC4.
The test circuit TC1 receives the trigger signal ST1 through wireless transmission in the test mode, and tests the connection of the electronic component AE1 according to the trigger signal ST1. Furthermore, the test circuit TC1 includes a coil circuit CL1. In the test mode, the coil circuit CL1 receives an external trigger signal ST1 through wireless transmission, and provides a test signal SNC1 to the electronic component AE1. Similarly, the test circuits TC2, TC3, and TC4 may respectively receive the trigger signals ST2, ST3, and ST4 through wireless transmission in the test mode, and test the connection of the electronic components AE2, AE3, and AE4 according to the trigger signals ST2, ST3, and ST4. Taking the unit AU1 as an example, the coil circuit CL1 in the test circuit TC1 receives the trigger signal ST1 and further provides a test signal SNC1 to the electronic component AE1 to test whether the connection of the electronic component AE1 is abnormal.
Similarly, the coil circuit in the test circuit TC2 receives the trigger signal ST2, converts the trigger signal ST2 into a test signal SNC2, and further provides the test signal SNC2 to the electronic component AE2 to test whether the connection of the electronic component AE2 is abnormal. The coil circuit in the test circuit TC3 receives the trigger signal ST3, converts the trigger signal ST3 into a test signal SNC3, and further provides the test signal SNC3 to the electronic component AE3 to test whether the connection of the electronic component AE3 is abnormal. The coil circuit in the test circuit TC4 receives the trigger signal ST4, converts the trigger signal ST4 into a test signal SNC4, and further provides the test signal SNC4 to the electronic component AE4 to test whether the connection of the electronic component AE4 is abnormal.
It is worth mentioning here that in the test mode, the test circuits TC1 to TC4 respectively provide corresponding test signals according to the received trigger signals. The electronic components AE1 to AE4 respectively operate in response to corresponding test signals in the test mode. In this way, in the test mode, the connection status of the electronic components AE1 to AE4 may be acquired. In addition, the test circuits TC1 to TC4 receive one of the trigger signals ST1 to ST4 through wireless transmission. In this way, in the test mode, the situation of using other external electronic devices to inspect the connection of electronic components may be avoided or reduced, and the convenience of the connection inspection of the electronic components in the electronic device 100 may be improved.
In this embodiment, the trigger signals ST1 to ST4 may have the same waveform. The trigger signals ST1 to ST4 may be the same trigger signal. Therefore, the test signals SNC1 to SNC4 may be the same signal. In some embodiments, the waveforms of the trigger signals ST1 to ST4 are not completely the same. Therefore, the waveforms of the test signals SNC1 to SNC4 may not be completely the same.
In this embodiment, the electronic device 100 including four units AU1 to AU4 is taken as an example. However, the disclosure is not limited to the number or arrangement of units. The number of units in the disclosure may be one or more.
In this embodiment, the unit AU1 further includes a control circuit CC1. The control circuit CC1 is electrically connected to the first end of the electronic component AEL In the operation mode, the control circuit CC1 provides an operation signal SC1 to the electronic component AE1. The unit AU2 further includes a control circuit CC2. The control circuit CC2 is coupled to the electronic component AE2. The control circuit CC2 provides an operation signal SC2 to the electronic component AE2 in the operation mode. The unit AU3 further includes a control circuit CC3. The control circuit CC3 is coupled to the electronic component AE3. The control circuit CC3 provides an operation signal SC3 to the electronic component AE3 in the operation mode. Furthermore, the unit AU4 further includes a control circuit CC4. The control circuit CC4 is coupled to the electronic component AE4. The control circuit CC4 provides an operation signal SC4 to the electronic component AE4 in the operation mode.
In this embodiment, the electronic device 100 further includes the scan lines LS1 and LS2 and the data lines LD1 and LD2, but the disclosure is not limited thereto. The scan line LS1 is coupled to the control circuits CC1 and CC2. The scan line LS2 is coupled to the control circuits CC3 and CC4. The data line LD1 is coupled to the control circuits CC1 and CC3. The data line LD2 is coupled to the control circuits CC2 and CC4. The electronic device 100 may provide the scan signal SS1 to the control circuits CC1 and CC2 through the scan line LS1 during the first period of the operation mode, and provide the scan signal SS2 to the control circuit CC3 and CC4 through the scan line LS2 during the second period of the operation mode. Therefore, the control circuit CC1 provides the operation signal SC1 according to the data signal SD1 on the data line LD1 in the first period. The control circuit CC2 provides the operation signal SC2 according to the data signal SD2 on the data line LD2 in the first period. The control circuit CC3 provides the operation signal SC3 according to the data signal SD1 on the data line LD1 in the second period. The control circuit CC4 provides the operation signal SC4 according to the data signal SD2 on the data line LD2 in the first period.
In this embodiment, the first end of the electronic component AE1 is electrically connected to the control circuit CC1. The second end of the electronic component AE1 is electrically connected to the reference low voltage VSS (e.g., ground, the disclosure is not limited thereto).
Taking the unit AU1 as an example, the electronic component AE1 is, for example, a light-emitting component. The light-emitting component may be a light-emitting diode of any form. The first end of the electronic component AE1 is electrically connected to the test circuit TC1, and the second end of the electronic component AE1 is electrically connected to the reference low voltage VSS. The first end of the electronic component AE1 may be an anode. The second end of the electronic component AE1 may be a cathode. In this example, when the connection of the electronic component AE1 in the unit AU1 is correct, the electronic component AE1 is in a forward bias state in response to the test signal SNC1 in the test mode (i.e., the voltage of the first end of the electronic component AE1 is greater than the voltage of the second end of the electronic component AE1). Thus, the electronic component AE1 provides a light signal L1. In other words, when the electronic component AE1 provides the light signal L1 in the test mode, the connection of the electronic component AE1 in the unit AU1 is determined to be correct. On the other hand, if the connection of the electronic component AE1 in the unit AU1 is abnormal (e.g., the electronic component AE1 is disconnected, short-circuited, or the cathode and anode connections are wrong). Then the electronic component AE1 does not provide the light signal L1 in the test mode. In other words, when the electronic component AE1 does not provide the light signal L1 in the test mode, the connection of the electronic component AE1 in the unit AU1 is determined to be abnormal. In this example, the light signal L1 is a light signal of red light, blue light, green light, or other colors. In the operation mode, when the connection of the electronic component AE1 in the unit AU1 is correct, the electronic component AE1 is in a forward bias state in response to the operation signal SC1 (i.e., the voltage of the first end of the electronic component AE1 is greater than the voltage of the second end of the electronic component AE1).
Taking the unit AU1 again as an example, the electronic component AE1 is, for example, a modulation component. The modulation component may be a varactor. The first end of the electronic component AE1 is electrically connected to the test circuit TC1, and the second end of the electronic component AE1 is electrically connected to the reference low voltage VSS (e.g., ground, the disclosure is not limited thereto). The first end of the electronic component AE1 may be a cathode. The second end of the electronic component AE1 may be an anode. In this example, when the connection of the electronic component AE1 in the unit AU1 is correct, the electronic component AE1 is in a forward bias state in response to the test signal SNC1 in the test mode (i.e., the voltage of the first end of the electronic component AE1 is greater than the voltage of the second end of the electronic component AE1). Thus, the electronic component AE1 provides a light signal L1. In other words, when the electronic component AE1 provides the light signal L1 in the test mode, the connection of the electronic component AE1 in the unit AU1 is determined to be correct. On the other hand, if the connection of the electronic component AE1 in the unit AU1 is abnormal (e.g., the electronic component AE1 is disconnected, short-circuited, or the cathode and anode connections are wrong). Then the electronic component AE1 does not provide the light signal L1 in the test mode. In other words, when the electronic component AE1 does not provide the light signal L1 in the test mode, the connection of the electronic component AE1 in the unit AU1 is determined to be abnormal. In this example, the light signal L1 is an infrared signal. The light signal L1 is a light signal generated by the recombination of electrons and electron holes located near the PN junction in the electronic component AE1 based on the forward bias state. In the operation mode, when the connection of the electronic component AE1 in the unit AU1 is correct, the electronic component AE1 is in a reverse bias state in response to the operation signal SC1 (i.e., the voltage of the first end of the electronic component AE1 is less than the voltage of the second end of the electronic component AE1) for modulating at least one of the frequency, phase, and amplitude of the electromagnetic waves output and input from the electronic device 100.
Similar to the aforementioned operation of the unit AU1, the disclosure may determine whether the connection of the electronic components AE2 to AE4 is correct based on the light signals L2 to L4 provided by the units AU2 to AU4 in the test mode.
In this embodiment, in the test mode, the light signals provided by the electronic components AE1 to AE4 may be captured by an image capture device. For example, if the image capture device does not capture the light signal L1 from the electronic component AE1 in the test mode, it means that the connection of the electronic component AE1 is abnormal.

When the electronic device is an antenna device, the test circuit TC1 may further include a radio frequency isolation circuit RFC1. The radio frequency isolation circuit RFC1 is electrically connected to the coil circuit CL1 and the electronic component AE1. The radio frequency isolation circuit RFC1 prevents the intensity of the radio frequency in the electronic component AE1 from being reduced. In some embodiments, the radio frequency isolation circuit RFC1 may be omitted based on actual usage requirements.
In this embodiment, the reference voltage VR is provided by, for example, the radio frequency isolation circuit RFC1 or an external voltage circuit (not shown), and the disclosure is not limited to the method of providing the reference voltage VR. In this embodiment, the coil circuit CL1 may be implemented by an induction coil or an inductor. The coil circuit CL1 receives the trigger signal ST1 through magnetic field coupling.

On the other hand, in the time period TD2 when the voltage difference between the voltage value of the reference voltage VR minus the voltage value of the trigger signal ST1 is less than or equal to the threshold voltage value of the switch circuit, the switch circuit SW1 is turned off for the time period TD2.
Based on the above, the test signal SNC1 is at least part of the negative half cycle signal of the trigger signal ST1. The switch circuit SW1 transmits the test signal SNC1 to the first end of the electronic component AE1. It should be noted that since the voltage value of the reference voltage VR is substantially equal to the voltage value of the reference low voltage VSS, thus the voltage value of the test signal SNC1 is less than the voltage value of the reference low voltage VSS. If the connection of the electronic component AE1 is correct, the electronic component AE1 enters the forward voltage state during the time period TD1 based on the voltage value of the test signal SNC1 and the reference low voltage VSS. During the time period TD1, the electronic component AE1 provides the light signal L1.
In some embodiments, the switch circuit SW1 may be implemented by other suitable types of transistor switches.
In some embodiments, the switch circuit SW1 may include a determination circuit and a switch (not shown). The determination circuit determines the voltage value of the trigger signal ST1 and the voltage value of the reference voltage VR. When the voltage value of the trigger signal ST1 is less than the voltage value of the reference voltage VR, the switch circuit SW1 is turned on. Therefore, the test signal SNC1 in the trigger signal ST1 is transmitted. On the other hand, when the voltage value of the trigger signal ST1 is greater than or equal to the voltage value of the reference voltage VR, the switch circuit SW1 is turned off.
In some embodiments, the switch circuit SW1 may be omitted. Therefore, in the test mode, the electronic component AE1 enters the forward voltage state and the reverse voltage state, and provides the light signal L1 in the forward voltage state.
In some embodiments, the electronic component AE1 is, for example, a light-emitting component. The voltage value of the test signal SNC1 is greater than the voltage value of the reference voltage VR. When the voltage value of the trigger signal ST1 is greater than the voltage value of the reference voltage VR, the switch circuit SW1 is turned on to transmit the test signal SNC1. In this embodiment, the trigger signal ST1 is an AC signal. The voltage value of the reference voltage VR is substantially equal to the voltage value of the reference low voltage VSS. Thus, the test signal SNC1 is at least part of the positive half cycle of the trigger signal ST1. The switch circuit SW1 transmits the test signal SNC1 to the first end of the electronic component AE1. The switch circuit SW1 is realized by, for example, a P-type transistor (but the disclosure is not limited thereto).

In this embodiment, the trigger signal ST1 is, for example, an ultraviolet light signal. The light signal L1 is red light, blue light, green light, infrared light, or other signals with different wavelengths than the trigger signal ST1.

The second end of the electronic component AE5 is electrically connected to the reference low voltage VSS.
The test circuit TC1 provides the test signal SNC1 to the electronic component AE1 and the electronic component AE5 in the test mode. It is thereby determined whether the connection of the electronic component AE1 in the unit AU1 and the connection of the electronic component AE5 in the unit AU5 are correct. For example, if the electronic component AE1 provides the light signal L1 in the test mode, the connection of the electronic component AE1 in the unit AU1 is correct. If the electronic component AE1 does not provide the light signal L1 in the test mode, the connection of the electronic component AE1 in the unit AU1 is abnormal. For example, if the electronic component AE5 provides the light signal L5 in the test mode, the connection of the electronic component AE5 in the unit AU5 is correct. If the electronic component AE5 does not provide the light signal L5 in the test mode, the connection of the electronic component AE5 in the unit AU5 is abnormal.
