AI Technical Summary
The existing display panels have a risk of burn during aging, mainly due to abnormal single-ended crimping, which leads to a large current entering the panel from the single-ended.
A display panel is designed, which is connected to the driving circuit through a first panel driving terminal through a second switching module, and the second panel driving terminal is connected to the driving circuit through a first switching module. When this design is crimped between the display panel and the circuit board, if a single-ended crimping abnormality occurs, the signals at both ends cannot be sent to the driving circuit normally, so as to determine whether the single-ended crimping abnormality is crimped abnormally by lighting up the current, avoiding burns caused by high current during aging.
It effectively reduces the risk of burns on the display panel when it ages, improves the yield of the product, and improves the performance of the display device.

[0055] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0057] Please refer to Figure 1-4As shown, a related display module 100 includes a display panel 1, the display panel 1 includes a display area 11 and a non-display area 12, the non-display area 12 is arranged 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 a panel terminal, and the circuit board 2 includes a circuit board terminal, which is used to transmit the driving signal to the driving circuit 3 through the panel terminal when the circuit board terminal is pressed and aligned with the panel terminal.
[0058] Please continue to refer to Figure 2-4 As shown, in order to improve the display uniformity of the display panel 1, the driving signal is usually input into the driving circuit 3 from both ends. Therefore, the bonding area 15 will be 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 driving signal to improve the display uniformity of the display panel 1. After the circuit board terminals are crimped with the panel terminals, the circuit board 2 at least partially covers the bonding area 15, wherein the covering area M refers to Figure 1 As shown, Figure 4 In order to show the circuit board terminals and panel terminals, the main body of the circuit board 2 is not shown.
[0059] After long-term research, the inventors found that since the driving signals input at both ends are consistent, when the single-end crimping is abnormal due to crimping fixture pressure, fixture damage or crimping misalignment, the driving signal at this end cannot be input to the display panel 1, and the display panel 1 can still light up normally under the driving signal at the other end. During the aging test, the single-end crimping abnormality will cause a large current to be input from the single end, causing the display panel 1 to burn.
[0060] Based on this, the present 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 is provided in an embodiment of the present application. The display panel 1 includes a display area 11 and a non-display area 12 . The non-display area 12 includes a bonding area 15 . The bonding area 15 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 drive terminal 41 and a first switch signal terminal 42, the second panel terminal group 5 includes a second panel drive terminal 51 and a second switch signal terminal 52, the first panel drive terminal 41 is connected to the drive circuit 3 through the second switch module 7, the second panel drive terminal 51 is connected to the drive circuit 3 through the first switch module 6, the control end of the first switch module 6 is connected to the first switch signal terminal 42, and the control end 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 the display panel 1 and the circuit board 2 are crimped together and a single-end crimping abnormality occurs, the signals at both ends cannot be normally given to the driving circuit 3. Therefore, it is possible to determine whether the single-end crimping abnormality is present based on the display panel lighting current, thereby preventing a large current from entering the display panel 1 from a single end during aging and causing burns. The display panel 1 is effectively protected, the risk of burns to the display panel 1 during aging is reduced, and the product yield is improved.
[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 the circuit board 2 are crimped, if there is an abnormality such as single-end crimping misalignment (taking the abnormality at the end where the first circuit board drive terminal 211 is located as an example), the signal cannot be normally input into the first panel drive terminal 41 and the first switch signal terminal 42, that is, the signal cannot normally enter the drive circuit 3 through the first panel drive terminal 41. At the same time, the first switch module 6 connected to the first switch signal terminal 42 cannot be turned on normally, resulting in the signal also being unable to normally enter the drive circuit 3 through the second panel drive terminal 51. At this time, the display panel lighting current will be abnormal. Therefore, it is possible to determine whether a single-end abnormality occurs by 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 drive terminals 41 and a plurality of first switch modules 6, and the second panel terminal group 5 includes a plurality of second panel drive terminals 51 and a plurality of second switch modules 7. Each first panel drive terminal 41 is connected to the drive circuit 3 through a second switch module 7, and each second panel drive terminal 51 is connected to the drive circuit 3 through a first switch module 6.
[0069] Specifically, multiple first panel driving terminals 41 are used to drive sub-pixels of different colors, and multiple second panel driving terminals 51 are used to drive sub-pixels of different colors. By connecting each first panel driving terminal 41 to the driving circuit 3 through a second switch module 7, and connecting each second panel driving terminal 51 to the driving circuit 3 through a first switch module 6, the target sub-pixels can be lit up individually or simultaneously.
[0070] Please continue to refer to Figure 5 As shown, in one embodiment, the control ends 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 at the same time; the control ends 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 at the same time.
[0071] Among them, a second switch module 7 controls multiple first panel drive terminals 41 to be turned on or off at the same time, and a first switch module 6 controls multiple second panel drive terminals 51 to be turned on or off at the same time, which is beneficial to saving costs and realizing device miniaturization.
[0072] In another embodiment, the control ends 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 at the same time; or, the control ends 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 at the same time.
[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 all the first switch modules 6 are controlled 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 ends of all the second switch modules 7 are connected to the second switch signal terminal 52 , so that all the second switch modules 7 are controlled by the second switch signal terminal 52 .
[0075] In one embodiment, a plurality of first panel drive terminals 41 and first switch signal terminals 42 are arranged along a first direction (such as the X direction in the figure), and a plurality of second panel drive terminals 51 and second switch signal terminals 52 are arranged along the first direction. Since the panel drive terminals and the switch signal terminals are arranged in the same direction, when the display panel 1 and the circuit board 2 are misaligned in single-end crimping, the panel drive terminals and the switch signal terminals in the end are all misaligned, resulting in that the signals at both ends cannot be normally provided to the drive circuit 3. Therefore, it can be judged whether the single-end crimping is abnormal based on the display panel lighting 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 to achieve double-end input.
[0077] In one embodiment, the first switch module 6 is a P-type transistor or an N-type transistor, and the second switch module 7 is a P-type transistor or an N-type transistor. Specifically, the first switch module 6 is a P-type transistor, and the second switch module 7 is a P-type transistor; or, the first switch module 6 is an N-type transistor, and the second switch module 7 is an N-type transistor, which is not specifically limited.
[0078] In one embodiment, the first switch module 6 and the second switch module 7 are both prepared in the same layer as the driving circuit 3. Specifically, when the display panel is prepared, the transistors in the first switch module 6 and the second switch module 7 are prepared at the same time as the transistors in the driving circuit 3, which is conducive to reducing costs and improving preparation efficiency.
[0079] Preferably, the first end of the first switch module 6 is connected to the first panel drive terminal 41, and the second end of the first switch module 6 is connected to the drive circuit 3; the first end of the second switch module 7 is connected to the second panel drive terminal 51, and the second end of the second switch module 7 is connected to the drive 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, the first panel driving terminal 41 is connected to the driving circuit 3 through one end of the first signal line 81, and the second switch module 7 is arranged on the first signal line 81 to turn on or off the first signal line 81; the second panel driving terminal 51 is connected to the driving circuit 3 through the second signal line 82, and the first switch module 6 is arranged on the second signal line 82 to turn on or off the second signal line 82. Specifically, after 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; after 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 end of the first switch module 6 is connected to the first switch signal terminal 42 through the third signal line 83, and the control end of the second switch module 7 is connected to the second switch signal terminal 52 through the fourth signal line 84. The signal on the first switch signal terminal 42 reaches the first switch module 6 through the third signal line 83, and the signal on the second switch signal terminal 52 reaches the second switch module 7 through the fourth signal line 84.
[0082] The above signal can be generated by a signal generator, the signal generated by the signal generator can be edited by a computer through a predetermined program, and the signal generator performs output driving according to the predetermined editing program; at the same time, the signal generator can detect the voltage value and current value of the signal.
[0083] Based on the same inventive concept, another embodiment of the present 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 the circuit board terminals are used to be crimped with the first panel drive terminal 41, some of the circuit board terminals are used to be crimped with the first switch signal terminal 42, some of the circuit board terminals are used to be crimped with the second panel drive terminal 51, and some of the circuit board terminals are used to be crimped 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, the 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 drive terminal 211 and a first detection signal terminal 212, and the second circuit board terminal group 22 includes a second circuit board drive terminal 221 and a second detection signal terminal 222. The first circuit board drive terminal 211 is used to connect with the first panel drive terminal 41, the first detection signal terminal 212 is used to connect with the first switch signal terminal 42, the second circuit board drive terminal 221 is used to connect with the second panel drive terminal 51, and the second detection signal terminal 222 is used to connect with the second switch signal terminal 52.
[0086] After the display panel 1 is crimped with the circuit board 2, a signal is 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 a signal is 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 when the display panel 1 is crimped with the circuit board 2, the signals at both ends cannot be normally given to the drive circuit 3. Therefore, it is possible to determine whether the single-end crimping abnormality occurs based on the display panel lighting current, thereby avoiding burns caused by a large current entering the display panel 1 from a single end during aging, thereby effectively protecting the display panel 1, reducing the risk of burns of the display panel 1 during aging, and improving the product yield.
[0087] Reference Figure 7 As shown, based on the same inventive concept, another embodiment of the present application further discloses an aging control method, which is applied to the display module in the above embodiment. The aging control method in this embodiment includes the following steps:
[0088] Step S10: crimping the first panel terminal group 4 and the second panel terminal group 5 to the circuit board terminals on the circuit board 2 respectively.
[0089] Step S20 , configuring signals on the first switch signal terminal 42 and the second switch signal terminal 52 through the circuit board terminal to conduct the first switch module 6 and the second switch module 7 .
[0090] Step S30 , configuring signals on the first panel driving terminal 41 and the second panel driving terminal 51 through the circuit board terminals, so as to perform a lighting test on the display panel 1 through the driving circuit 3 .
[0091] Step S40 , detecting state parameters of the display panel 1 during the lighting test.
[0092] Step S50: When the state parameter is within the threshold range, an aging process is performed on the display panel 1;
[0093] Step S60: When the state parameter is not within the threshold range, the display panel 1 is powered off without performing the aging process.
[0094] Specifically, the first circuit board terminal group 21 includes a first circuit board drive terminal 211 and a first detection signal terminal 212, and the second circuit board terminal group 22 includes a second circuit board drive terminal 221 and a second detection signal terminal 222. The first circuit board drive terminal 211 is used to connect to the first panel drive terminal 41, and the first detection signal terminal 212 is used to connect to the first switch signal terminal 42. The second circuit board drive terminal 221 is used to connect to the second panel drive terminal 51, and the second detection signal terminal 222 is used to connect to the second switch signal terminal 52.
[0095] Among them, after the display panel 1 and the circuit board 2 are crimped, if there is an abnormality such as single-end crimping misalignment, the signal cannot normally enter the drive circuit 3 through the first panel drive terminal 41, and cannot normally enter the drive circuit 3 through the second panel drive terminal 51, that is, both-end signals cannot enter the drive circuit 3. At this time, the display panel state parameters will be abnormal. Therefore, it can be judged whether a single-end abnormality occurs through the state parameters.
[0096] In one embodiment, the state parameter is voltage or current. In another embodiment, the state parameter is voltage and current, and the judgment is made by combining voltage and current to improve the accuracy of the judgment. Among them, the state parameter can be obtained by testing when the panel drive terminal and the circuit board drive terminal are normally connected, and the state parameter can be corrected to obtain the threshold range. For example, the state parameter can be expanded or reduced by a certain multiple to obtain a more accurate threshold range.
[0097] Based on the same inventive concept, another embodiment of the present application further discloses a display device, which includes the display module in the above embodiment. Further, the display device includes a mobile phone, VR equipment, computer, television, car display equipment, etc.
[0098] A display device provided in this embodiment includes a display module, and the display module includes a display panel 1. In the display panel 1, the first panel drive terminal 41 is connected to the drive circuit 3 through the second switch module 7, and the second panel drive terminal 51 is connected to the drive circuit 3 through the first switch module 6. The control end of the first switch module 6 is connected to the first switch signal terminal 42, and the control end of the second switch module 7 is connected to the second switch signal terminal 52. When the display panel 1 and the circuit board 2 are crimped and a single-end crimping abnormality occurs, the signals at both ends cannot be normally given to the drive circuit 3. Therefore, it can be judged whether the single-end crimping abnormality is based on the lighting current of the display panel, so as to avoid large current from entering the display panel 1 from the single end during aging to cause burns, effectively protect the display panel 1, reduce the risk of burns of the display panel 1 during aging, improve the product yield, and improve the performance of the display device.
