[0061] 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.

"Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0063] Please refer to Figure 1-3 As 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, and the non-display area 12 is arranged around the display area 11. The display panel 1 also includes a pixel unit 3 and a panel terminal, and the circuit board 2 includes a circuit board driving terminal, and the circuit board driving terminal is used to transmit a driving signal to the pixel unit 3 through the panel terminal when aligned with the panel terminal.

[0064] Please continue to refer to Figure 2-3 As shown, in order to improve the display uniformity of the display panel 1, the driving signal is usually input into the pixel unit 3 from both ends, so the non-display area 12 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, and 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.

[0065] Among them, the pixel unit 3 includes a first color sub-pixel 31, a second color sub-pixel 32 and a third color sub-pixel 33, the first panel terminal group 4 includes a first data signal terminal 61, a second data signal terminal 62 and first and third data signal terminals 63, and the second panel terminal group 5 also includes a first data signal terminal 61, a second data signal terminal 62 and a third data signal terminal 63.

[0066] After long-term research, the inventors found that since the driving signals input at both ends are consistent, when the driving signal at one end cannot be input to the display panel 1 due to the pressure of the crimping fixture or damage to the fixture, the pixel unit 3 can still light up normally under the driving signal at the other end. During the aging test, large current input from a single end can easily cause the display panel 1 to burn.

[0067] Based on this, the present application provides a display panel solution to solve the above problems.

[0071] The display panel 1 provided in the present embodiment sets two first data signal terminals 61 in the first panel terminal group 4 and two second data signal terminals 62 in the second panel terminal group 5. When a crimping abnormality occurs in one of the panel terminal groups, the two data signal terminals of the same type in the panel terminal group cannot transmit the data signal to the sub-pixel of the corresponding color, resulting in the sub-pixel of the corresponding color failing to be lit. The signal abnormality is thus accurately identified, and burns caused by a large current entering the display panel 1 from a single end during aging are avoided. The display panel 1 is effectively protected, the risk of burns of the display panel 1 during aging is reduced, and the product yield is improved.

A second switch module 72 is provided in the second sub-line 92, and the second switch module 72 is used to turn on or off the second sub-line 92.

[0074] Please continue to refer to Figure 4 As shown, in one embodiment, two ends of the first main line 81 are respectively connected to two first data signal terminals 61 , so that signals are input from two ends of the first main line 81 to improve the display uniformity of different columns of first color sub-pixels 31 .

[0078] The first switch module 71 can be controlled by the first switch signal terminal 42 and the second switch signal terminal 52, and the second switch module 72 can be controlled by the third switch signal terminal 43 and the fourth switch signal terminal 53, thereby realizing the lighting control of the sub-pixel.

[0082] In one embodiment, the third color sub-pixel 33 is a red sub-pixel, the first color sub-pixel 31 is one of a green sub-pixel and a blue sub-pixel, and the second color sub-pixel 32 is the other of a green sub-pixel and a blue sub-pixel. In the case of double-end input, data signals can be applied to the green sub-pixel and the blue sub-pixel in sequence to identify which end has an abnormal signal.

[0083] In another embodiment, the third color sub-pixel 33 is a green sub-pixel, the first color sub-pixel 31 is one of a red sub-pixel and a blue sub-pixel, and the second color sub-pixel 32 is the other of a red sub-pixel and a blue sub-pixel. In the case of double-end input, the data signal can be applied to the red sub-pixel and the blue sub-pixel in sequence to identify which end has an abnormal signal.

[0088] Different signals are used to implement different functions. The signal configured on the first drive signal terminal 41 may also include other signals, and the signal configured on the second drive signal terminal 51 may also include other signals, without specific limitation.

[0089] Preferably, the first drive signal terminal 41 and the second drive signal terminal 51 are connected, and the signals configured on the first drive signal terminal 41 and the second drive signal terminal 51 are the same or different, which can be specifically set as needed.

[0090] 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.

[0091] Reference Figure 8As 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 panel 1 in the above embodiment. The aging control method in this embodiment includes the following steps:

[0092] Step S10, configuring a data signal for lighting up the first color sub-pixel 31 on the two first data signal terminals 61, and detecting a first state parameter of the display panel 1;

[0093] Step S20 : ​​when the first state parameter is within the first threshold range, a data signal for lighting up the second color sub-pixel 32 is configured on the two second data signal terminals 62 , and the second state parameter of the display panel 1 is detected.

[0094] The aging control method provided in this embodiment sets two first data signal terminals 61 in the first panel terminal group 4 and two second data signal terminals 62 in the second panel terminal group 5. When a crimping abnormality occurs in one of the panel terminal groups, the two data signal terminals of the same type in the panel terminal group cannot transmit the data signal to the sub-pixel of the corresponding color, resulting in the sub-pixel of the corresponding color failing to be lit. This allows accurate identification of signal abnormalities, avoids large current from entering the display panel 1 from a single end during aging and causing burns, effectively protects the display panel 1, reduces the risk of burns to the display panel 1 during aging, and improves product yield.

[0095] In one embodiment, the step S10 further includes the following steps:

[0096] The first panel terminal group 4 and the second panel terminal group 5 are respectively crimped to the circuit board terminals on the circuit board 2; specifically, the first panel terminal group 4 is crimped to the first circuit board terminal group 21, and the second panel terminal group 5 is crimped to the second circuit board terminal group 22.

[0097] Preferably, in one embodiment, the method further comprises the following steps:

[0098] When the first state parameter is not within the first threshold range, the display panel 1 is powered off without performing the aging process.

[0099] Preferably, in one embodiment, the method further comprises the following steps:

[0100] When the second state parameter is not within the second threshold range, the display panel 1 is powered off without performing the aging process;

[0101] When the second state parameter is within the second threshold range, an aging process is performed on the display panel 1 .

[0102] Exemplarily, the second color sub-pixel 32 is a red sub-pixel, and the first color sub-pixel 31 is a green sub-pixel. First, a data signal for lighting the first color sub-pixel 31 is configured on the first data signal terminal 61. If the first circuit board terminal group 21 and the first panel terminal group 4 are crimped normally, the first color sub-pixel 31 will be lit. If the first circuit board terminal group 21 and the first panel terminal group 4 are crimped abnormally, the first color sub-pixel 31 will not be lit. Then, a data signal for lighting the second color sub-pixel 32 is configured on the second data signal terminal 62. If the second circuit board terminal group 22 and the second panel terminal group 5 are crimped normally, the second color sub-pixel 32 will be lit. If the second circuit board terminal group 22 and the second panel terminal group 5 are crimped abnormally, the second color sub-pixel 32 will not be lit. At the same time, after the sub-pixel is lit, the abnormality can be more accurately identified in combination with the state parameters.

[0103] In one embodiment, the first state parameter includes voltage or current, and the second state parameter includes voltage or current. In another embodiment, the first state parameter includes voltage and current, and the second state parameter includes voltage and current. Combining voltage and current is beneficial to improve accuracy.

[0104] In one embodiment, the first state parameter and the second state parameter are the same, and the first threshold range and the second threshold range are the same. Specifically, the first state parameter and the second state parameter can be voltage or current, or can include voltage and current at the same time. Since the luminous efficiency of different sub-pixels is different, the current driving different sub-pixels may be different, and therefore, the first threshold range and the second threshold range can be set to be the same or different.

[0105] Based on the same inventive concept, another embodiment of the present application further discloses a display device, which includes the display panel in the above embodiment. Further, the display device includes a mobile phone, VR equipment, computer, television, car display equipment, etc.

[0106] A display device provided in this embodiment has a display panel 1, by setting two first data signal terminals 61 in the first panel terminal group 4 and two second data signal terminals 62 in the second panel terminal group 5. When a crimping abnormality occurs in one of the panel terminal groups, the two data signal terminals of the same type in the panel terminal group cannot transmit the data signal to the sub-pixel of the corresponding color, resulting in the sub-pixel of the corresponding color failing to be lit, thereby accurately identifying the signal abnormality, avoiding burns caused by large current entering the display panel 1 from a single end during aging, effectively protecting the display panel 1, reducing the risk of burns of the display panel 1 during aging, improving the product yield, and improving the performance of the display device.

[0107] Although the present application has been described in conjunction with specific embodiments thereof, many alternatives, modifications and variations of these embodiments will be apparent to those skilled in the art in light of the foregoing description.
