[0055] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0057] Please refer to Figure 1-4As shown, a related display module 100 includes a display panel 1, which includes a display area 11 and a non-display area 12. The non-display area 12 is disposed around the display area 11, and one of the non-display areas 12 includes a bonding area 15. The display panel 1 also includes a driving circuit 3 and panel terminals. The circuit board 2 includes circuit board terminals, which are used to transmit driving signals to the driving circuit 3 through the panel terminals when the circuit board terminals are crimped and aligned with the panel terminals.
[0058] Please continue to refer to Figure 2-4 As shown, to improve the uniformity of the display on the display panel 1, the drive signal is typically input to the dual-ended drive circuit 3. Therefore, the bonding area 15 is provided with a first bonding area 13 and a second bonding area 14. The first bonding area 13 is provided with a first panel terminal group 4, and the second bonding area 14 is provided with a second panel terminal group 5. Correspondingly, the circuit board 2 includes a first circuit board terminal group 21 and a second circuit board terminal group 22. The circuit board terminals in the first circuit board terminal group 21 are used to connect with the panel terminals in the first panel terminal group 4, and the circuit board terminals in the second circuit board terminal group 22 are used to connect with the panel terminals in the second panel terminal group 5. The first circuit board terminal group 21 and the second circuit board terminal group 22 are configured with the same drive signal to improve the uniformity of the display on the display panel 1. After the circuit board terminals are pressed against the panel terminals, the circuit board 2 at least partially covers the bonding area 15, wherein the covered area M is defined by reference to... Figure 1 As shown, and Figure 4 To show the circuit board terminals and panel terminals, the main body of circuit board 2 is not shown.
[0059] Through long-term research, the inventors discovered that since the drive signals input at both ends are consistent, when a single-end crimping abnormality occurs due to reasons such as crimping fixture pressure, fixture damage, or crimping misalignment, the drive signal at that end cannot be input to the display panel 1. The display panel 1 can still be lit normally under the drive signal at the other end. However, during the aging test, a single-end crimping abnormality will cause a large current to be input from one end, resulting in burns to the display panel 1.
[0060] Based on this, this application provides a display panel solution to solve the above problems.
[0061] Please refer to Figure 1 and 5 As shown, a display panel 1 provided in an embodiment of this application is shown. The display panel 1 includes a display area 11 and a non-display area 12. The non-display area 12 is bound to a bonding area 15, which includes a first bonding area 13 and a second bonding area 14.
[0062] The display panel 1 also includes a driving circuit 3, a first panel terminal group 4, a second panel terminal group 5, a first switch module 6, and a second switch module 7. The driving circuit 3 is located in the display area 11, the first panel terminal group 4 is located in the first bonding area 13, and the second panel terminal group 5 is located in the second bonding area 14.
[0063] The first panel terminal group 4 includes a first panel driving terminal 41 and a first switch signal terminal 42. The second panel terminal group 5 includes a second panel driving terminal 51 and a second switch signal terminal 52. The first panel driving terminal 41 is connected to the driving circuit 3 through the second switch module 7. The second panel driving terminal 51 is connected to the driving circuit 3 through the first switch module 6. The control terminal of the first switch module 6 is connected to the first switch signal terminal 42. The control terminal of the second switch module 7 is connected to the second switch signal terminal 52.
[0064] The signal configured on the first switch signal terminal 42 is used to control the first switch module 6 to be turned on or off, and the signal configured on the second switch signal terminal 52 is used to control the second switch module 7 to be turned on or off.
[0065] When a single-end crimping abnormality occurs in the crimping of the display panel 1 and the circuit board 2, the signals from both ends cannot be normally sent to the drive circuit 3. Therefore, the crimping abnormality can be determined based on the display panel's lighting current. This prevents a large current from entering the display panel 1 from one end during aging and causing burns, effectively protecting the display panel 1, reducing the risk of burns during aging, and improving product yield.
[0066] Please refer to Figure 6 As shown, the circuit board 2 includes a first circuit board terminal group 21 and a second circuit board terminal group 22. The circuit board terminals in the first circuit board terminal group 21 are used to connect with the panel terminals in the first panel terminal group 4, and the circuit board terminals in the second circuit board terminal group 22 are used to connect with the panel terminals in the second panel terminal group 5.
[0067] After the display panel 1 and circuit board 2 are crimped together, if an abnormality such as misalignment occurs at one end (taking an abnormality at the end where the first circuit board drive terminal 211 is located as an example), the signal cannot be normally input to the first panel drive terminal 41 and the first switch signal terminal 42, meaning the signal cannot normally enter the drive circuit 3 through the first panel drive terminal 41. Simultaneously, the first switch module 6 connected to the first switch signal terminal 42 cannot be properly turned on, causing the signal to also fail to normally enter the drive circuit 3 through the second panel drive terminal 51. At this time, the display panel's lighting current will be abnormal. Therefore, the presence of a single-end abnormality can be determined by observing the lighting current.
[0068] Please continue to refer to Figure 5As shown, in one embodiment, the first panel terminal group 4 includes a plurality of first panel driving terminals 41 and a plurality of first switch modules 6, and the second panel terminal group 5 includes a plurality of second panel driving terminals 51 and a plurality of second switch modules 7. Each first panel driving terminal 41 is connected to the driving circuit 3 via a second switch module 7, and each second panel driving terminal 51 is connected to the driving circuit 3 via a first switch module 6.
[0069] Specifically, multiple first panel driving terminals 41 are used to drive different color sub-pixels, and multiple second panel driving terminals 51 are used to drive different color sub-pixels. By connecting each first panel driving terminal 41 to the driving circuit 3 through a second switch module 7, and each second panel driving terminal 51 to the driving circuit 3 through a first switch module 6, it is possible to light up the target sub-pixel individually or simultaneously.
[0070] Please continue to refer to Figure 5 As shown, in one embodiment, the control terminals of multiple first switch modules 6 are connected to the same first switch signal terminal 42, and the signal configured on the first switch signal terminal 42 is used to control the multiple first switch modules 6 to be turned on or off simultaneously; the control terminals of multiple second switch modules 7 are connected to the same second switch signal terminal 52, and the signal configured on the second switch signal terminal 52 is used to control the multiple second switch modules 7 to be turned on or off simultaneously.
[0071] In this system, a second switch module 7 controls multiple first panel drive terminals 41 to be turned on or off simultaneously, and a first switch module 6 controls multiple second panel drive terminals 51 to be turned on or off simultaneously. This helps to save costs and achieve device miniaturization.
[0072] In another embodiment, the control terminals of multiple first switch modules 6 are connected to the same first switch signal terminal 42, and the signal configured on the first switch signal terminal 42 is used to control the multiple first switch modules 6 to be turned on or off simultaneously; or, the control terminals of multiple second switch modules 7 are connected to the same second switch signal terminal 52, and the signal configured on the second switch signal terminal 52 is used to control the multiple second switch modules 7 to be turned on or off simultaneously.
[0073] Preferably, the first panel terminal group 4 includes a first switch signal terminal 42, and the control terminals of all the first switch modules 6 are connected to the first switch signal terminal 42, so that the control of all the first switch modules 6 can be realized through the first switch signal terminal 42.
[0074] Preferably, the second panel terminal group 5 includes a second switch signal terminal 52, and the control terminals of all the second switch modules 7 are connected to the second switch signal terminal 52, so that the control of all the second switch modules 7 can be realized through the second switch signal terminal 52.
[0075] In one embodiment, multiple first panel driving terminals 41 and first switch signal terminals 42 are arranged along a first direction (as shown by the X direction in the figure), and multiple second panel driving terminals 51 and second switch signal terminals 52 are also arranged along the first direction. Since the panel driving terminals and switch signal terminals are arranged in the same direction, when a single-end crimping misalignment occurs between the display panel 1 and the circuit board 2, all panel driving terminals and switch signal terminals at that end are misaligned, causing signals from both ends to be unable to be normally supplied to the driving circuit 3. Therefore, the crimping abnormality at one end can be determined based on the display panel's illumination current.
[0076] Preferably, the first bonding area 13 and the second bonding area 14 are arranged along the first direction to facilitate crimping with the circuit board 2 and realize dual-ended input.
[0077] In one embodiment, the first switching module 6 is a P-type transistor or an N-type transistor, and the second switching module 7 is a P-type transistor or an N-type transistor. Specifically, the first switching module 6 is a P-type transistor, and the second switching module 7 is a P-type transistor; or, the first switching module 6 is an N-type transistor, and the second switching module 7 is an N-type transistor, without any specific limitation.
[0078] In one embodiment, both the first switch module 6 and the second switch module 7 are fabricated on the same layer as the driving circuit 3. Specifically, during the fabrication of the display panel, the transistors in the first switch module 6 and the second switch module 7 are fabricated simultaneously with the transistors in the driving circuit 3, which helps to reduce costs and improve fabrication efficiency.
[0079] Preferably, the first end of the first switch module 6 is connected to the first panel driving terminal 41, and the second end of the first switch module 6 is connected to the driving circuit 3; the first end of the second switch module 7 is connected to the second panel driving terminal 51, and the second end of the second switch module 7 is connected to the driving circuit 3. The first end of the switch module is one of the source and drain of the transistor, the second end of the switch module is the other of the source and drain of the transistor, and the control end of the switch module is the gate of the transistor.
[0080] In one embodiment, the display panel 1 further includes a first signal line 81 and a second signal line 82. A first panel driving terminal 41 is connected to a driving circuit 3 through one end of the first signal line 81. A second switch module 7 is disposed on the first signal line 81 to turn the first signal line 81 on or off. A second panel driving terminal 51 is connected to the driving circuit 3 through the second signal line 82. A first switch module 6 is disposed on the second signal line 82 to turn the second signal line 82 on or off. Specifically, when the second switch module 7 is turned on, the first signal line 81 is turned on, and the signal on the first panel driving terminal 41 can reach the driving circuit 3 through the first signal line 81. When the first switch module 6 is turned on, the second signal line 82 is turned on, and the signal on the first panel driving terminal 41 can reach the driving circuit 3 through the second signal line 82.
[0081] Preferably, the display panel 1 further includes a third signal line 83 and a fourth signal line 84. The control terminal of the first switch module 6 is connected to the first switch signal terminal 42 via the third signal line 83, and the control terminal of the second switch module 7 is connected to the second switch signal terminal 52 via the fourth signal line 84. The signal from the first switch signal terminal 42 reaches the first switch module 6 via the third signal line 83, and the signal from the second switch signal terminal 52 reaches the second switch module 7 via the fourth signal line 84.
[0082] The aforementioned signals can be generated by a signal generator. The signals generated by the signal generator can be edited by a computer according to a predetermined program, and the signal generator can output and drive according to the predetermined edited program. At the same time, the signal generator can detect the voltage and current values of the signals.
[0083] Based on the same inventive concept, another embodiment of this application also discloses a display module, including the display panel 1 and circuit board 2 in the above embodiment. The circuit board 2 includes circuit board terminals, some of which are used to press with the first panel driving terminal 41, some of which are used to press with the first switch signal terminal 42, some of which are used to press with the second panel driving terminal 51, and some of which are used to press with the second switch signal terminal 52.
[0084] The circuit board terminals are used to configure signals on the first switch signal terminal 42 and the second switch signal terminal 52 to control the first switch module 6 and the second switch module 7 to be turned on or off; the circuit board terminals are also used to configure signals on the first panel drive terminal 41 and the second panel drive terminal 51 to perform a lighting test on the display panel 1.
[0085] Please continue to refer to Figure 6As shown, circuit board 2 includes a first circuit board terminal group 21 and a second circuit board terminal group 22. Specifically, the first circuit board terminal group 21 includes a first circuit board driving terminal 211 and a first detection signal terminal 212, and the second circuit board terminal group 22 includes a second circuit board driving terminal 221 and a second detection signal terminal 222. The first circuit board driving terminal 211 is used to connect to the first panel driving terminal 41, the first detection signal terminal 212 is used to connect to the first switch signal terminal 42, the second circuit board driving terminal 221 is used to connect to the second panel driving terminal 51, and the second detection signal terminal 222 is used to connect to the second switch signal terminal 52.
[0086] After the display panel 1 is crimped to the circuit board 2, signals are first configured on the first detection signal terminal 212 and the second detection signal terminal 222 to turn on the first switch module 6 and the second switch module 7. Then, signals are configured on the first circuit board drive terminal 211 and the second circuit board drive terminal 221 to light up the display panel 1 through the drive circuit 3. When a single-end crimping abnormality occurs in the crimping of the display panel 1 and the circuit board 2, the signals at both ends cannot be normally sent to the drive circuit 3. Therefore, the single-end crimping abnormality can be determined based on the lighting current of the display panel, which avoids the large current entering the display panel 1 from one end during aging and causing burns. This effectively protects the display panel 1, reduces the risk of burns to the display panel 1 during aging, and improves the product yield.
[0087] Reference Figure 7 As shown, based on the same inventive concept, another embodiment of this application also discloses an aging control method, applied to the display module in the above embodiment. The aging control method in this embodiment includes the following steps:
[0088] Step S10: Press the first panel terminal group 4 and the second panel terminal group 5 onto the circuit board terminals on the circuit board 2 respectively.
[0089] Step S20: Configure signals on the first switch signal terminal 42 and the second switch signal terminal 52 through the circuit board terminals to turn on the first switch module 6 and the second switch module 7.
[0090] Step S30: Configure signals on the first panel driver terminal 41 and the second panel driver terminal 51 through the circuit board terminals for lighting up the display panel 1 through the driver circuit 3.
[0091] Step S40: Detect the status parameters of display panel 1 during the lighting test.
[0092] Step S50: When the status parameters are within the threshold range, perform an aging process on the display panel 1.
[0093] Step S60: When the status parameters are not within the threshold range, power off the display panel 1 and do not perform the aging process.
[0094] Specifically, the first circuit board terminal group 21 includes a first circuit board driving terminal 211 and a first detection signal terminal 212, and the second circuit board terminal group 22 includes a second circuit board driving terminal 221 and a second detection signal terminal 222. The first circuit board driving terminal 211 is used to connect to the first panel driving terminal 41, the first detection signal terminal 212 is used to connect to the first switch signal terminal 42, the second circuit board driving terminal 221 is used to connect to the second panel driving terminal 51, and the second detection signal terminal 222 is used to connect to the second switch signal terminal 52.
[0095] If a misalignment or other abnormality occurs after the display panel 1 and circuit board 2 are crimped together, the signal will be unable to enter the drive circuit 3 through either the first panel drive terminal 41 or the second panel drive terminal 51. In other words, neither end of the signal can enter the drive circuit 3. This will cause the display panel status parameters to become abnormal. Therefore, the presence of a single-end abnormality can be determined by checking the status parameters.
[0096] In one embodiment, the state parameter is voltage or current. In another embodiment, the state parameter is both voltage and current; the accuracy of the judgment is improved by combining voltage and current. Specifically, the state parameter can be obtained by testing under normal connection between the panel driver terminal and the circuit board driver terminal, and the threshold range can be obtained by correcting the state parameter, for example, by expanding or shrinking the state parameter by a certain factor, thereby obtaining a more accurate threshold range.
[0097] Based on the same inventive concept, another embodiment of this application discloses a display device, which includes the display module in the above embodiments. Furthermore, the display device includes mobile phones, VR devices, computers, televisions, in-vehicle display devices, etc.
[0098] This embodiment provides a display device including a display module, which includes a display panel 1. In the display panel 1, a first panel driving terminal 41 is connected to a driving circuit 3 via a second switch module 7, and a second panel driving terminal 51 is connected to the driving circuit 3 via a first switch module 6. The control terminal of the first switch module 6 is connected to a first switch signal terminal 42, and the control terminal of the second switch module 7 is connected to a second switch signal terminal 52. When a single-end crimping abnormality occurs between the display panel 1 and the circuit board 2, signals from both ends cannot be normally supplied to the driving circuit 3. Therefore, the single-end crimping abnormality can be determined based on the display panel's illumination current, preventing large currents from entering the display panel 1 from one end and causing burns during aging. This effectively protects the display panel 1, reduces the risk of burns during aging, improves product yield, and enhances the performance of the display device.
