[0051] 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.

[0052] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be the usual meanings understood by people with ordinary skills in the field to which the present application belongs.

"Connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "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.

[0053] AMOLED (Active-Matrix Organic Light-Emitting Diode) display panels mainly use low-temperature polycrystalline oxide (Low Temperature Polycrys talline Oxide, abbreviated as LTPO) or low-temperature polycrystalline silicon (Low Temperature Poly-Silicon, abbreviated as LTPS) as the backplane for thin film transistor (Thin Film Transistor, abbreviated as TFT), which is increasingly used in various display fields.

[0054] At present, the lifespan of AMOLED products is an important indicator for measuring product performance. Since the manufacturing process of AMOLED products is complex and prone to process fluctuations, process fluctuations will directly affect the product lifespan, causing some product performance to fail to meet requirements.

[0055] After long-term research, the inventor of this application found that the temperature of the AMOLED display panel during the aging process will affect the aging speed, thereby affecting the life of the display panel. Based on this, this application provides a display panel aging control solution to solve the above problem, with specific reference to the following embodiments.

[0056] Reference Figure 1 As shown, an embodiment of the present application discloses a display panel aging control method, the display panel aging control method comprising the following steps:

[0057] Step S1, obtaining the self-temperature of the display panel during the aging process. Specifically, an aging fixture is used to assist the display panel in the aging process, and the display panel is subjected to a temperature test; in addition, the display panel can also be measured by a temperature sensor to obtain the self-temperature. It should be noted that the self-temperature is the temperature of the display panel, not the ambient temperature.

[0058] The temperature of the display panel during the aging process may be obtained at certain time intervals, for example, every 0.5 seconds, 1 second, or 2 seconds.

[0059] Step S2: performing aging control on the display panel based on a first relationship between the acquired self-temperature and a preset self-temperature range.

[0060] Specifically, the first relationship includes that the acquired self-temperature is within a preset self-temperature range, and that the acquired self-temperature is outside the preset self-temperature range; wherein the acquired self-temperature is outside the preset self-temperature range includes that the acquired self-temperature is greater than an upper limit value in the preset self-temperature range, and that the acquired self-temperature is less than a lower limit value in the preset self-temperature range. The preset self-temperature range is a temperature range corresponding to a safe temperature for aging control of the display panel.

[0061] The display panel aging control method provided in this embodiment performs aging control on the display panel based on the first relationship between the acquired display panel's own temperature and the preset own temperature range, so that the display panel's own temperature during the aging process can be within the preset own temperature range, thereby accelerating the aging of the display panel while avoiding damage to the display panel, thereby effectively prolonging the life of the display panel and improving the performance of the display panel.

[0062] In one embodiment, step S2, based on the first relationship between the acquired self-temperature and the preset self-temperature range, performs aging control on the display panel, including: based on the first relationship between the acquired self-temperature and the preset self-temperature range, adjusting the self-temperature of the display panel by adjusting the first power supply voltage of the display panel, in one embodiment, adjusting the self-temperature of the display panel by adjusting the ELVSS voltage of the display panel. Among them, the ELVSS voltage is usually a negative value, and an increase in the ELVSS voltage will cause the aging power consumption of the display panel to decrease, resulting in a decrease in the self-temperature of the display panel; a decrease in the ELVSS voltage will cause the aging power consumption of the display panel to increase, resulting in an increase in the self-temperature of the display panel. It should be noted that adjusting the ELVSS voltage of the display panel will not affect the aging current of the display panel. Therefore, in the process of adjusting the ELVSS voltage, the aging effect of the display panel will not be affected by the change of the aging current.

[0063] Reference Figure 2 As shown, in one embodiment, the self-temperature of the display panel is adjusted by adjusting the ELVSS voltage of the display panel based on the first relationship between the acquired self-temperature and the preset self-temperature range, including the following steps:

[0064] Step S21: In response to the first relationship that the acquired self-temperature is greater than the upper limit value in the preset self-temperature range, the ELVSS voltage of the display panel is increased until the self-temperature of the display panel is within the preset self-temperature range. The self-temperature of the display panel is lowered by increasing the ELVSS voltage to ensure that the self-temperature of the display panel is within the preset self-temperature range, thereby preventing the display panel from being damaged by excessively high self-temperature.

[0065] Please continue to refer to Figure 2 As shown, in one embodiment, the self-temperature of the display panel is adjusted by adjusting the ELVSS voltage of the display panel based on the first relationship between the acquired self-temperature and the preset self-temperature range, and further includes the following steps:

[0066] Step S22: In response to the first relationship that the acquired self-temperature is less than the lower limit value in the preset self-temperature range, the ELVSS voltage of the display panel is reduced until the self-temperature of the display panel is within the preset self-temperature range. The self-temperature of the display panel is increased by reducing the ELVSS voltage to ensure that the self-temperature of the display panel is within the preset self-temperature range, which can accelerate the aging of the display panel and increase the life of the display panel.

[0067] Please continue to refer to Figure 2As shown, in one embodiment, the self-temperature of the display panel is adjusted by adjusting the ELVSS voltage of the display panel based on the first relationship between the acquired self-temperature and the preset self-temperature range, including the following steps:

[0068] Step S23: In response to the first relationship that the acquired self-temperature is within the preset self-temperature range, the ELVSS voltage of the display panel is kept unchanged, so as to ensure that the display panel continues to age within the preset self-temperature range.

[0069] Reference Figure 3 As shown, in one embodiment, before step S1, obtaining the temperature of the display panel itself during the aging process, the following steps are included:

[0070] Step S200, obtaining an aging current of the display panel, and performing aging control on the display panel based on a second relationship between the obtained aging current and a preset aging current range. The aging current of the display panel can be obtained by the second power supply voltage and the first power supply voltage;

[0071] Specifically, the aging current of the display panel is obtained through the ELVDD voltage and the ELVSS voltage.

[0072] Reference Figure 4 As shown, in one embodiment, in step S200, based on the second relationship between the acquired aging current and the preset aging current range, aging control is performed on the display panel, including the following steps:

[0073] Step S210: In response to the second relationship that the aging current is within the preset aging current range, continue to age the display panel, wherein the aging current is ensured to be within the preset aging current range to avoid the aging effect being affected by too small an aging current and the display panel being burned due to too large an aging current.

[0074] Please continue to refer to Figure 4 As shown, in one embodiment, in step S200, based on the second relationship between the acquired aging current and the preset aging current range, aging control is performed on the display panel, including the following steps:

[0075] Step S220, in response to the second relationship that the acquired aging current is not within the preset aging current range, adjusting the data voltage and / or the second power supply voltage until the aging current is within the preset aging current range. In one embodiment, in response to the second relationship that the aging current is not within the preset aging current range, adjusting the Vdata voltage and / or the VDD voltage until the aging current is within the preset aging current range. Increasing the Vdata voltage and / or the VDD voltage can increase the aging current, and reducing the Vdata voltage and / or the VDD voltage can reduce the aging current.

[0076] After step S200, the aging current of the display panel can be within the preset aging current range. On this basis, step S1 is executed, that is, the aging current is controlled first, and then the temperature of the display panel itself is controlled; at the same time, when the temperature of the display panel itself is adjusted, the aging current is kept unchanged, and the aging effect of the display panel will not be affected by the change of the aging current.

[0077] Reference Figure 5 As shown, in one embodiment, before step S1, obtaining the temperature of the display panel itself during the aging process, the following steps are included:

[0078] Step S100, writing an initial aging voltage to the display panel for aging, wherein the initial aging voltage is a safe voltage within a preset aging voltage range.

[0079] Reference Figure 6 As shown, in another embodiment, step S1 is located before step S100.

[0080] Please refer to Table 1, which is a comparison of the aging results of the display panel aging control method provided in this embodiment and the existing aging control method; wherein, the aging time corresponding to the three sub-pixels R, G, and B in the display panel is different, and the display panel aging control method provided in this embodiment reduces the ELVSS voltage from -5V to -15.6V, so that the aging temperature is increased from 25-30℃ to 45-55℃, thereby increasing the T95 life of the display panel from 250-270 hours to 350-360 hours. Among them, T95 is defined as the luminous intensity decaying to 95% of the initial value. Therefore, the display panel aging control method provided in this embodiment can significantly increase the service life of the display panel.

[0083] It should be noted that the method of the embodiment of the present application can be performed by a single device, such as a computer or server. The method of this embodiment can also be applied to a distributed scenario and completed by multiple devices cooperating with each other. In the case of such a distributed scenario, one of the multiple devices can only perform one or more steps in the method of the embodiment of the present application, and the multiple devices will interact with each other to complete the described method.

[0084] It should be noted that the above describes some embodiments of the present application. Other embodiments are within the scope of the appended claims. In some cases, the actions or steps recorded in the claims can be performed in an order different from that in the above embodiments and still achieve the desired results. In addition, the processes depicted in the accompanying drawings do not necessarily require the specific order or continuous order shown to achieve the desired results. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.

[0085] Reference Figure 7 As shown, based on the same inventive concept, corresponding to any of the above-mentioned embodiments and methods, another embodiment of the present application further provides an aging control device for a display panel, which includes the following modules:

[0086] The first acquisition module is used to obtain the self-temperature of the display panel during the aging process; specifically, the aging jig is used to assist the display panel in the aging process and the temperature of the display panel is tested; in addition, the temperature of the display panel can also be measured by a temperature sensor to obtain the above self-temperature. It should be noted that the above self-temperature is the temperature of the display panel, not the ambient temperature.

[0087] The temperature of the display panel during the aging process may be obtained at certain time intervals, for example, every 0.5 seconds, 1 second, or 2 seconds.

[0088] The first control module is used to perform aging control on the display panel based on a first relationship between the acquired self-temperature and a preset self-temperature range.

[0089] Specifically, the first relationship includes that the acquired self-temperature is within a preset self-temperature range, and that the acquired self-temperature is outside the preset self-temperature range; wherein the acquired self-temperature is outside the preset self-temperature range includes that the acquired self-temperature is greater than an upper limit value in the preset self-temperature range, and that the acquired self-temperature is less than a lower limit value in the preset self-temperature range. The preset self-temperature range is a temperature range corresponding to a safe temperature for aging control of the display panel.

[0090] The display panel aging control system provided in the present embodiment performs aging control on the display panel based on the first relationship between the acquired self-temperature of the display panel and the preset self-temperature range, so that the self-temperature of the display panel during the aging process is within the preset self-temperature range, thereby accelerating the aging of the display panel while avoiding damage to the display panel, thereby effectively prolonging the life of the display panel and improving the performance of the display panel.

[0091] In one embodiment, the first control module is specifically used for:

[0092] Based on the first relationship between the acquired self-temperature and the preset self-temperature range, the self-temperature of the display panel is adjusted by adjusting the first power supply voltage of the display panel. In one embodiment, based on the first relationship between the acquired self-temperature and the preset self-temperature range, the self-temperature of the display panel is adjusted by adjusting the ELVSS voltage of the display panel. Among them, the ELVSS voltage is usually a negative value. An increase in the ELVSS voltage will cause the aging power consumption of the display panel to decrease, resulting in a decrease in the self-temperature of the display panel; a decrease in the ELVSS voltage will cause the aging power consumption of the display panel to increase, resulting in an increase in the self-temperature of the display panel. It should be noted that adjusting the ELVSS voltage of the display panel will not affect the aging current of the display panel. Therefore, during the adjustment process of the ELVSS voltage, the aging effect of the display panel will not be affected by the change in the aging current.

[0093] Reference Figure 8 As shown, in one embodiment, the first control module includes:

[0094] The first response module is used to increase the ELVSS voltage of the display panel in response to the first relationship that the acquired self-temperature is greater than the upper limit value in the preset self-temperature range until the self-temperature of the display panel is within the preset self-temperature range. The self-temperature of the display panel is reduced by increasing the ELVSS voltage to ensure that the self-temperature of the display panel is within the preset self-temperature range, thereby preventing the display panel from being damaged by excessively high self-temperature.

[0095] The second response module is used to reduce the ELVSS voltage of the display panel in response to the first relationship that the acquired self-temperature is less than the lower limit value in the preset self-temperature range until the self-temperature of the display panel is within the preset self-temperature range. The self-temperature of the display panel is increased by reducing the ELVSS voltage to ensure that the self-temperature of the display panel is within the preset self-temperature range, which can accelerate the aging of the display panel and increase the life of the display panel.

[0096] The third response module is used to keep the ELVSS voltage of the display panel unchanged in response to the first relationship that the acquired self-temperature is within the preset self-temperature range, so as to ensure that the display panel continues to age within the preset self-temperature range.

[0098] A second acquisition module, used for acquiring an aging current of a display panel;

[0099] The second control module is used to perform aging control on the display panel based on a second relationship between the acquired aging current and a preset aging current range. Specifically, the aging current of the display panel is acquired through the ELVDD signal line or the ELVSS signal line.

[0100] Reference Fig.10 As shown, in one embodiment, the second control module includes:

[0101] The fourth response module is used to respond to the second relationship that the aging current is within the preset aging current range and continue to age the display panel, wherein the aging current is ensured to be within the preset aging current range to avoid the aging effect being affected by too small an aging current and to avoid the display panel being burned due to too large an aging current.

[0102] Please continue to refer to Fig.10 As shown, in one embodiment, the second control module includes:

[0103] The fifth response module, in response to the second relationship that the aging current is not within the preset aging current range, adjusts the Vdata voltage and / or the VDD voltage until the aging current is within the preset aging current range. Increasing the Vdata voltage and / or the VDD voltage can increase the aging current, and decreasing the Vdata voltage and / or the VDD voltage can decrease the aging current.
