TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of display, and in particular, to a display device and a display apparatus. BACKGROUND

[0002] ESD (Electro-Static discharge) is a key factor affecting the stability and life of the actual application of a product. In actual use, high-voltage static electricity carried by the human body or external objects can be released to the inside of the device in the moment of contact with the device, and the high-voltage pulse generated is extremely easy to damage internal devices. The traditional protection method is mainly static protection, but when static electricity is abnormal, it cannot be repaired in time and effectively, so it is difficult to eliminate the interference caused by static electricity, and it is also difficult to eliminate the persistent interference caused by static electricity, thereby seriously affecting the reliability of the display device. Therefore, there is currently a technical problem of low reliability of the display device caused by static electricity.

[0003] The above content is only used to assist in understanding the technical solutions of the embodiments of the present application, and does not represent the acknowledgement of the above content as prior art. SUMMARY

[0004] The main purpose of the embodiments of the present application is to provide a display device and a display apparatus, which aims to solve the technical problem of low reliability of the display device caused by static electricity.

[0005] To achieve the above-mentioned purpose, the display device provided by the embodiments of the present application comprises a power manager, a timing controller and a driver, the power manager comprises a power reset module, a voltage module and a first static electricity detection module connected in sequence, the timing controller comprises a voltage driving module, a second static electricity detection module and a timing output module connected in sequence, the driver comprises a differential output module, a third static electricity detection module and a driving reset module connected in sequence, the output end of the first static electricity detection module is connected to the input end of the voltage driving module, the differential output end in the timing controller is connected to the input end of the differential output module, and the output end of the voltage driving module is also connected to the input end of the timing output module.

[0006] The power reset module is configured to reset the voltage module when the first static electricity detection module detects that the output of the voltage module is abnormal. The voltage driving module is configured to reset when the second static electricity detection module detects that the output of the timing output module is abnormal. The driving reset module is configured to adjust the differential output module when the third static electricity detection module detects that the output of the differential output module is abnormal, so that the output of the differential output module returns to normal.

[0007] In one embodiment, the timing controller further includes a timing control module and a communication interface. The voltage feedback terminal of the timing control module is connected to the abnormal output terminal of the first electrostatic detection module, and the communication interface is connected to the input terminal of the power reset module. If the first electrostatic detection module detects that the difference between the current voltage output by the voltage module and the preset voltage is not within the preset normal voltage range, it determines that the output of the voltage module is abnormal. If there is an abnormality in the output of the voltage module, the first electrostatic detection module generates a voltage abnormality signal and sends the voltage abnormality signal to the timing control module. Upon receiving a voltage anomaly signal, the timing control module generates a power reset signal and sends the power reset signal to the power reset module via the communication interface. Upon receiving the power reset signal, the power reset module resets the voltage module.

[0008] In one embodiment, the timing feedback terminal of the timing output module is also connected to the abnormal input terminal of the voltage module. The second electrostatic detection module is used to detect the high-level duration of the output signal of the timing output module, and is also used to send a timing abnormal signal to the voltage module through the timing output module when the difference between the high-level duration and the preset normal duration is not within the preset normal duration range. Upon receiving the timing error signal, the voltage module resets the voltage drive module.

[0009] In one embodiment, the timing controller further includes a timing reset unit connected to the voltage drive module; The timer resetter is used to periodically reset the voltage drive module according to a preset reset cycle.

[0010] In one embodiment, the third electrostatic detection module includes a phase detection unit and a voltage detection unit, and the drive reset module includes a first adjustment unit and a second adjustment unit; The detection terminals of the phase detection unit and the voltage detection unit are both connected to the output terminal of the differential output module. The output terminal of the phase detection unit is connected to the input terminal of the first adjustment unit. The output terminal of the voltage detection unit is connected to the adjustment feedback terminal of the voltage module. The input terminal of the second adjustment unit is connected to the adjustment control terminal of the voltage module. The output terminals of the first adjustment unit and the second adjustment unit are both connected to the input terminal of the differential output module.

[0011] In one embodiment, the phase detection unit is used to detect the phase difference between the positive and negative signals in the differential signal output by the differential output module, and if the phase difference is not within a preset normal phase range, it is determined that the differential output module has a phase abnormality. In the event of a phase anomaly in the differential output module, the phase detection unit outputs a phase adjustment signal to the first adjustment unit, which adjusts the phase difference of the differential signal until the phase difference is within a preset normal phase range.

[0012] In one embodiment, the second adjustment unit further includes at least two resistors connected in series, wherein the first end of the first resistor in the at least two resistors connected in series is used as the input end of the second adjustment unit, and the second end of the first resistor is used as the output end of the second adjustment unit. The second adjustment unit is used to detect the common-mode voltage of the differential signal output by the differential output module. If the common-mode voltage is not within the preset normal common-mode range, it is determined that there is a voltage abnormality in the differential output module. In the event of a voltage anomaly in the differential output module, the second adjustment unit outputs a voltage adjustment signal to the voltage module, and the voltage module gradually adjusts the voltage output to the second adjustment unit until the common-mode voltage is within a preset normal common-mode range.

[0013] In one embodiment, the display device further includes a device control module. The detection feedback terminal of the device control module is connected to a first electrostatic discharge (ESD) detection module, a second ESD detection module, and a third ESD detection module. The priority control terminal of the device control module is also connected to the power reset module, the second ESD detection module, and the drive reset module. The device control module is used to execute a reset instruction operation according to a preset repair priority when the first electrostatic detection module detects an abnormality in the output of the voltage module, the second electrostatic detection module detects an abnormality in the output of the timing output module, and / or the third electrostatic detection module detects an abnormality in the output of the differential output module. The reset indication operation includes: when there are at least two abnormal modules, determining the target abnormal module with the highest reset priority among the at least two abnormal modules, sending a reset indication signal to the reset control module corresponding to the target abnormal module to reset the target abnormal module; after the target abnormal module is reset, if there are still remaining abnormal modules with output abnormalities among the at least two abnormal modules, then sending a reset indication signal to the reset control module corresponding to the remaining abnormal modules. The preset repair priorities include: the reset priority of the voltage module is higher than the reset priority of the voltage drive module, and the reset priority of the voltage drive module is higher than the reset priority of the differential output module; The abnormal module is a voltage module, a timing output module, or a differential output module. The at least two abnormal modules are different, and the remaining abnormal module is a timing output module or a differential output module. The reset control module corresponding to the voltage module is the power reset module, the reset control module corresponding to the timing output module is the second electrostatic detection module, and the reset module corresponding to the differential output module is the drive reset module.

[0014] In one embodiment, the reset control terminal of the device control module is connected to the abnormal feedback terminal of the power reset module and the drive feedback terminal of the voltage drive module. When the device control module detects that the abnormal feedback terminal is at a low level and / or the drive feedback terminal is at a preset medium level, the device control module controls the display device to restart in order to reset the voltage module and the voltage drive module.

[0015] In addition, to achieve the above objectives, this application embodiment also provides a display device, which includes a display panel and a display apparatus as described above; the differential output module of the driver in the display apparatus is connected to the display panel.

[0016] The one or more technical solutions proposed in this application have at least the following technical effects: By setting a first electrostatic discharge (ESD) detection module inside the power manager, a second ESD detection module inside the timing controller, and a third ESD detection module inside the driver, this application enables the power manager, timing controller, and driver in the display device to perform individual ESD detection. Since each ESD detection module detects whether the output is abnormal, for example, the first ESD detection module detects whether the output of the voltage module is abnormal, the second ESD detection module detects whether the output of the timing output module is abnormal, and the third ESD detection module detects whether the output of the differential output module is abnormal, when displaying each frame of image in the display device, the voltage module will output the signal first, followed by the timing output module, and finally the driver. Since each ESD detection module is set inside the power manager, timing controller, and driver respectively.

[0017] Therefore, electrostatic discharge (ESD) anomalies can be detected sequentially through various ESD detection modules. That is, if the voltage module, timing output module, and differential output module all malfunction due to ESD, the first ESD detection module will detect the voltage module anomaly first, followed by the second ESD detection module detecting the timing output module anomaly, and the third ESD detection module detecting the differential output module. This achieves priority detection of the voltage module, followed by sequential detection of the timing output module and differential output module. Since the first ESD detection module can detect the voltage module anomaly first, and the voltage module also includes a power reset module, when an ESD anomaly is detected, the power reset module can be used to reset the voltage module. Since the first electrostatic discharge (ESD) detection module in the power manager is connected to the voltage drive module, and its input is connected to the voltage module, the first ESD detection module can output the voltage required by the voltage module. The voltage required by the timing output module in the timing controller is provided by the voltage module through the first ESD detection module and the voltage drive module. Therefore, repairing the voltage module first can ensure the reliability of the repair and avoid the situation where the timing output module cannot be repaired if the voltage module is not repaired (because the abnormality of the timing output module may be caused by the abnormality of the voltage module).

[0018] Furthermore, in this application, the voltage drive module can also be reset in the event of an anomaly in the timing output module, thereby repairing the voltage drive module and ensuring normal output of the timing output module. Additionally, the drive reset module can adjust the differential output module in the event of an anomaly, restoring its output to normal and thus repairing the differential output module. In summary, this application can perform electrostatic discharge (ESD) detection and repair on the voltage module, timing output module, and differential output module. It also supports prioritizing the repair of the voltage module before sequentially repairing the voltage drive module in the timing controller and the differential output module in the driver, thereby achieving ESD repair and improving its reliability, ultimately enhancing the reliability of the display device.

[0023] The objectives, features, and advantages of the embodiments described in this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0024] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of the embodiments of this application and are not intended to limit the embodiments of this application.

[0025] To better understand the technical solutions of the embodiments of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0026] With the increasing complexity and integration of display products, ESD (electrostatic discharge) capability has become crucial, directly impacting the stability and lifespan of products in practical applications. ESD refers to the sudden release of charge when a charged object comes into contact with a conductor, finding a path through the conductor. In real-world applications, humans or other objects that come into contact with display products often carry high-voltage static electricity. This high-voltage static electricity can cause irreversible damage to various components through the product's circuitry upon release. When a repairable ESD anomaly occurs, the power management chip (PMIC), timing controller (TCON), and driver chip in the display device may all malfunction. Without ESD repair, this can lead to display abnormalities and other issues, resulting in low reliability of the display device.

[0027] Therefore, this embodiment provides a display device that prioritizes electrostatic discharge (ESD) repair of the power manager, followed by ESD repair of the timing controller and driver sequentially. This achieves both ESD detection and repair, improving the reliability of ESD repair and thus enhancing the overall reliability of the display device. Specifically: This embodiment sets up a first electrostatic discharge (ESD) detection module inside the power manager, a second ESD detection module inside the timing controller, and a third ESD detection module inside the driver. This allows the power manager, timing controller, and driver in the display device to perform individual ESD detection. Each ESD detection module detects whether the output is abnormal. For example, the first ESD detection module detects whether the output of the voltage module is abnormal, the second ESD detection module detects whether the output of the timing output module is abnormal, and the third ESD detection module detects whether the output of the differential output module is abnormal. When displaying each frame of image in the display device, the voltage module outputs a signal first, followed by the timing output module, and finally the driver. Since each ESD detection module is set up inside the power manager, timing controller, and driver respectively.

[0028] Therefore, electrostatic discharge (ESD) anomalies can be detected sequentially through various ESD detection modules. That is, if the voltage module, timing output module, and differential output module all malfunction due to ESD, the first ESD detection module will detect the voltage module anomaly first, followed by the second ESD detection module detecting the timing output module anomaly, and the third ESD detection module detecting the differential output module. This achieves priority detection of the voltage module, followed by sequential detection of the timing output module and differential output module. Since the first ESD detection module can detect the voltage module anomaly first, and the voltage module also includes a power reset module, when an ESD anomaly is detected, the power reset module can be used to reset the voltage module. Since the first electrostatic discharge (ESD) detection module in the power manager is connected to the voltage drive module, and its input is connected to the voltage module, the first ESD detection module can output the voltage required by the voltage module. The voltage required by the timing output module in the timing controller is provided by the voltage module through the first ESD detection module and the voltage drive module. Therefore, repairing the voltage module first can ensure the reliability of the repair and avoid the situation where the timing output module cannot be repaired if the voltage module is not repaired (because the abnormality of the timing output module may be caused by the abnormality of the voltage module).

[0029] Furthermore, in this embodiment, in the event of an anomaly in the timing output module, the voltage drive module can also be reset, thereby repairing the voltage drive module and ensuring normal output from the timing output module. Additionally, the drive reset module can adjust the differential output module when there is an anomaly in its output, restoring its output to normal and thus repairing the differential output module. In summary, this embodiment can perform electrostatic discharge (ESD) detection and repair on the voltage module, timing output module, and differential output module. It also supports prioritizing the repair of the voltage module before sequentially repairing the voltage drive module in the timing controller and the differential output module in the driver, thereby achieving ESD repair and improving its reliability, ultimately enhancing the reliability of the display device.

[0030] Based on this, embodiments of this application provide a display device, referring to... Figure 1 , Figure 1This is a schematic diagram of the display device according to an embodiment of this application. The display device includes a power manager 100, a timing controller 200, and a driver 300. The power manager 100 includes a power reset module 110, a voltage module 120, and a first electrostatic discharge (ESD) detection module 130 connected in sequence. The timing controller 200 includes a voltage drive module 210, a second ESD detection module 220, and a timing output module 230 connected in sequence. The driver 300 includes a differential output module 310, a third ESD detection module 320, and a drive reset module 330 connected in sequence. The output terminal of the first ESD detection module 130 is connected to the input terminal of the voltage drive module 210. The differential output terminal of the timing controller 200 is connected to the input terminal of the differential output module 310. The output terminal of the voltage drive module 210 is also connected to the input terminal of the timing output module 230. The power reset module 110 is used to reset the voltage module 120 when the first electrostatic detection module 130 detects an abnormality in the output of the voltage module 120. The voltage drive module 210 is reset when the second electrostatic detection module 220 detects an abnormal output of the timing output module 230. The drive reset module 330 is used to adjust the differential output module 310 so that the output of the differential output module 310 returns to normal when the third electrostatic detection module 320 detects an abnormality in the output of the differential output module 310.

[0031] It should be noted that the power manager 100 can specifically be a PMIC, the timing controller 200 can specifically be a TCON, and the driver 300 can specifically be a driver in the display device. Each of the power manager 100, timing controller 200, and driver 300 is equipped with an electrostatic discharge (ESD) detection module.

[0032] The power manager 100 includes a power reset module 110, a voltage module 120, and a first electrostatic discharge (ESD) detection module 130 connected in sequence. Specifically, the output terminal of the power reset module 110 is connected to the input terminal of the voltage module 120. Multiple voltage signals output by the voltage module 120 are output from the first ESD detection module 130, meaning that multiple voltage signals pass through the first ESD detection module 130. Therefore, the first ESD detection module 130 can detect whether each voltage signal output by the voltage module 120 has an ESD anomaly, thereby improving the reliability of the detection. When the first ESD detection module 130 detects an anomaly in any voltage signal, it determines that the output of the voltage module 120 is abnormal. When an ESD anomaly exists, the power reset module 110 can reset the voltage module 120, thereby restoring the voltage module 120 to normal and eliminating interference caused by ESD. In this embodiment, the voltage signal output by the voltage module 120 can be output from the first ESD detection module 130.

[0033] The timing controller 200 includes a voltage drive module 210, a second electrostatic discharge (ESD) detection module 220, and a timing output module 230 connected in sequence. Specifically, the output terminal of the voltage drive module 210 is connected to the input terminal of the timing output module 230. The output terminal of the voltage drive module 210 is also connected to the input terminal of the second ESD detection module 220. The output terminal of the timing output module 230 is also connected to the monitoring terminal of the second ESD detection module 220. The second ESD detection module 220 can receive the signal output by the timing output module 230 through the monitoring terminal so that the second ESD detection module 220 can detect whether the output of the timing output module 230 is abnormal.

[0034] The voltage drive module 210 is also connected to the timing output module 230. The voltage required by the timing output module 230 is provided by the voltage drive module 210. The voltage required by the voltage drive module 210 is provided by the voltage module 120. Specifically, the voltage module 120 outputs to the voltage drive module 210 through the first electrostatic detection module 130. The output terminal of the voltage module 120 can output multiple voltage signals. The output terminal of the voltage module 120 can include multiple sub-output terminals. The voltage signals output by different sub-output terminals can be different. The corresponding first electrostatic detection module 130 can also include multiple sub-output terminals. The input terminal of the voltage drive module 210 can be connected to the sub-output terminal in the first electrostatic detection module 130 that provides voltage to the voltage drive module 210.

[0035] When an abnormal output is detected in the timing output module 230, the voltage drive module 210 can be reset. Since the voltage required by the timing output module 230 is provided by the voltage drive module 210, resetting the voltage drive module 210 is equivalent to resetting the timing output module 230, thereby allowing the timing controller 200 to return to normal.

[0036] The driver 300 includes a differential output module 310, a third electrostatic discharge (ESD) detection module 320, and a drive reset module 330 connected in sequence. The input terminal of the differential output module 310 can be connected to the differential output terminal in the timing controller 200. The third ESD detection module 320 can be connected to the output terminal of the differential output module 310. The input terminal of the drive reset module 330 can be connected to the output terminal of the third ESD detection module 320, and the output terminal of the drive reset module 330 can be connected to the adjustment terminal of the differential output module 310. The third ESD detection module 320 can detect the output terminal of the differential output module 310. Specifically, the third ESD detection module 320 can detect the phase difference and / or common-mode voltage of the differential signal output by the differential output module 310 to detect whether the differential signal output by the differential output terminal is abnormal. The drive reset module 330 can adjust the phase difference and / or common-mode voltage of the differential signal output by the differential output module 310 until the output of the differential output module 310 returns to normal.

[0037] Since the electrostatic discharge (ESD) detection modules (first ESD detection module 130, second ESD detection module 220, and third ESD detection module 320) are respectively located in the power manager 100, the timing controller 200, and the driver 300, and since the voltage module 120 outputs the signal first when the display device displays each frame of image, followed by the timing output module 230, and finally the driver 300, ESD detection can be prioritized on the voltage module 120 in the power manager 100, followed by the timing output module 230 and the differential output module 310. This facilitates the priority reset of the voltage module 120 in the event of abnormalities in the voltage module 120, timing output module 230, and differential output module 310, followed by the reset of the voltage driver module 210. The driver reset module 330 adjusts the differential output module 310 to restore its output to normal, thereby improving the efficiency and reliability of ESD repair.

[0038] Therefore, electrostatic discharge (ESD) anomalies can be detected sequentially through various ESD detection modules. That is, if the voltage module 120, timing output module 230, and differential output module 310 all malfunction due to ESD, the first ESD detection module 130 will detect the voltage module 120 anomaly first, followed by the second ESD detection module 220 detecting the timing output module 230 anomaly, and the third ESD detection module 320 detecting the differential output module 310. This achieves priority detection of the voltage module 120, followed by sequential detection of the timing output module 230 and differential output module 310. Since the first ESD detection module 130 can detect the voltage module 120 anomaly first, and the voltage module 120 also includes a power reset module 110, when an ESD anomaly is detected in the voltage module 120, the power reset module 110 can be used to reset the voltage module. The voltage module 120 can also be reset first, since the first electrostatic discharge (ESD) detection module 130 in the power manager 100 is connected to the voltage drive module 210, and the input terminal of the first ESD detection module 130 is connected to the voltage module 120. That is, the first ESD detection module 130 can output the voltage required by the voltage module 120. The voltage required by the timing output module 230 in the timing controller 200 is provided by the voltage module 120 through the first ESD detection module 130 and the voltage drive module 210. Therefore, repairing the voltage module 120 first can ensure the reliability of the repair and avoid the situation where the timing output module 230 cannot be repaired if the voltage module 120 is not repaired (because the abnormality of the timing output module 230 may be caused by the abnormality of the voltage module 120).

[0039] Furthermore, in this embodiment, when the timing output module 230 malfunctions, the voltage drive module 210 can also be reset, thereby repairing the voltage drive module 210 and ensuring the timing output module 230 outputs normally. Additionally, the drive reset module 330 can adjust the differential output module 310 when its output is abnormal, restoring its output to normal, thus repairing the differential output module 310. In summary, this embodiment can perform electrostatic discharge (ESD) detection on the voltage module 120, timing output module 230, and differential output module 310, and also perform repairs. It supports prioritizing the repair of the voltage module 120, followed by sequential repairs of the voltage drive module 210 in the timing controller 200 and the differential output module 310 in the driver 300, thereby achieving ESD repair and improving its reliability, ultimately enhancing the reliability of the display device.

[0040] In one feasible embodiment, please refer to Figure 2The timing controller 200 further includes a timing control module 240 and a communication interface. The voltage feedback terminal of the timing control module 240 is connected to the abnormal output terminal of the first electrostatic detection module 130, and the communication interface is connected to the input terminal of the power reset module 110. If the first electrostatic detection module 130 detects that the difference between the current voltage output by the voltage module 120 and the preset voltage is not within the preset normal voltage range, it determines that the output of the voltage module 120 is abnormal. If there is an abnormality in the output of the voltage module 120, the first electrostatic detection module 130 generates a voltage abnormality signal and sends the voltage abnormality signal to the timing control module 240. After receiving a voltage abnormality signal, the timing control module 240 generates a power reset signal and sends the power reset signal to the power reset module 110. Upon receiving the power reset signal, the power reset module 110 resets the voltage module 120.

[0041] It should be noted that the timing controller 200 also includes a timing control module 240. The voltage feedback terminal of the timing control module 240 is connected to the abnormal output terminal of the first electrostatic discharge (ESD) detection module 130. When the first ESD detection module 130 detects an abnormal output from the voltage module 120, it can generate a voltage abnormality signal and send it to the voltage feedback terminal of the timing control module 240 through the abnormal output terminal of the first ESD detection module 130. For example, in Figure 2 The port connecting the timing control module 240 to the first electrostatic discharge (ESD) detection module 130 is the voltage feedback terminal, and the port connecting the first ESD detection module 130 to the timing control module 240 is the abnormal output terminal. The communication interface can also be located on the timing control module 240.

[0042] The preset normal voltage range can be set in advance based on actual conditions. This embodiment does not impose specific limitations on this. Since the output terminal of the voltage module 120 includes multiple sub-output terminals, each sub-output terminal can output a voltage signal. For example, refer to... Figure 2In the diagram, voltage module 120 outputs multiple voltage signals to the first electrostatic discharge (ESD) detection module 130, and the first ESD detection module 130 also outputs multiple voltage signals. These multiple voltage signals can be VAA (Analog Voltage for Array), VCOM (Common Voltage), VGL (Gate Low Voltage), VGH (Gate High Voltage), and VDD, etc. This embodiment does not specifically limit these signals; they can be set based on actual conditions. Different voltage signals may reflect different voltages. Therefore, in this embodiment, if the difference between the current voltage output by any sub-output terminal of voltage module 120 and the preset voltage corresponding to that sub-output terminal is not within the preset normal voltage range, it is determined that the output of voltage module 120 is abnormal. In this embodiment, the preset voltages corresponding to different sub-output terminals may be the same or different; this embodiment does not specifically limit this. Furthermore, in... Figure 2 The voltage drive module 210, the second electrostatic detection module 220, and the timing output module 230 in the timing controller 200 are not shown in the figure.

[0043] The first electrostatic discharge (ESD) detection module 130 can generate a voltage abnormality signal and send it to the timing control module 240 when the output of the voltage module 120 is abnormal. The voltage abnormality signal indicates that the voltage module 120 has an output abnormality. Upon receiving the voltage abnormality signal, the timing control module 240 can generate a power reset signal, which instructs the power reset module 110 to reset the voltage module 120. The communication interface in the timing controller 200 is the interface connecting to the I2C (Inter-Integrated Circuit) bus. The communication interface can be connected to the input terminal of the power reset module 110 via the I2C bus. In this embodiment, the timing controller 200 also sends the power reset signal to the power reset module 110 via the I2C bus.

[0044] When the power reset module 110 receives the power reset signal, it can reset the voltage module 120. For example, the power reset module 110 can send a power reset signal to the voltage module 120, and the voltage module 120 can automatically restart and reset.

[0045] This embodiment detects whether there is an electrostatic discharge (ESD) abnormality in the voltage module 120 by detecting the current voltage output of any sub-output terminal in the voltage module 120. This facilitates timely reset of the voltage module 120 in the event of an ESD abnormality, thereby performing ESD repair on the voltage module 120. This achieves ESD repair of the voltage manager and improves the reliability of the display device, because the voltage of many devices in the display device is provided by the voltage manager. For example, the voltage of the timing output module 230 in the timing controller 200 is provided by the voltage module 120 in the voltage manager.

[0046] In one feasible embodiment, please refer to Figure 3 The timing feedback terminal of the timing output module 230 is also connected to the drive reset terminal of the voltage module 120. The second electrostatic detection module 220 is used to detect the high-level duration of the output signal of the timing output module 230, and is also used to send a timing abnormality signal to the voltage module 120 through the timing output module 230 when the difference between the high-level duration and the preset normal duration is not within the preset normal duration range. When the voltage module 120 receives the timing error signal, it resets the voltage drive module 210.

[0047] It should be noted that the second electrostatic discharge detection module 220 can detect whether the output of the timing output module 230 is abnormal. The signal output by the timing output module 230 can be a control signal. The timing output module 230 can output multiple control signals, such as CK signal (Clock Signal), STV signal (Start Vertical Signal), LC signal (Level Control Signal), and CP signal (Clock Pulse Signal), etc. This embodiment does not make specific limitations on this. The second electrostatic discharge detection module 220 can detect the high-level duration of each control signal output by the timing output module 230. The preset normal duration may be different for different control signals. The preset normal duration can be set based on the actual situation. This embodiment does not make specific limitations on this.

[0048] If the difference between the high-level duration of any control signal and the preset normal duration of the control signal is not within the preset normal duration range, the second electrostatic detection module 220 will generate a timing abnormality signal and send the timing abnormality signal to the voltage module 120 through the timing output module 230.

[0049] A timing error signal indicates an abnormality in the output of the timing controller 200, caused by ESD. Upon receiving the timing error signal, the voltage module 120 resets the voltage drive module 210, thereby achieving electrostatic discharge (ESD) repair of the timing controller 200. For example, the timing error signal can be a low-level signal.

[0050] In this embodiment, the timing output module 230 may also include a timing feedback terminal, and the power manager 100 may also include a data register. The timing feedback terminal may be connected to the input terminal of the data register, and the output terminal of the data register may be connected to the abnormal input terminal of the voltage module 120. Figure 3 The data register is not shown in the diagram. Figure 3 The port connecting the timing output module 230 to the voltage module 120 is the timing feedback terminal, and the port connecting the voltage module 120 to the timing output module 230 is the exception input terminal. A data register can be connected between the voltage module 120 and the timing output module 230. When the timing output module 230 outputs normally, the timing feedback terminal is at a high level. When the timing output module 230 outputs abnormally, the second electrostatic register can pull the timing feedback terminal low through the timing abnormal signal. Then, the data register detects that the timing feedback terminal is at a low level, and the data register can control the voltage module 120 to reset the voltage drive module 210. Specifically, it can control the voltage module 120 to stop outputting voltage to the voltage drive module 210. That is, the voltage output by the sub-output terminal of the voltage module 120 used to provide voltage to the voltage drive module 210 can be set to 0. Then, the voltage output by the corresponding sub-output port of the first electrostatic detection module 130 will also be set to 0. After the preset stop time, the voltage module 120 will output voltage to the voltage drive module 210 again, thereby resetting the voltage drive module 210 and also resetting the timing controller 200.

[0051] For example, voltage module 120 provides voltages of 3.3V, 1.8V, and 0.9V to voltage drive module 210 through first electrostatic detection module 130. When an output abnormality is detected in timing output module 230, voltage module 120 can stop outputting 3.3V, 1.8V, and 0.9V to voltage drive module 210 and resume output after a preset stop time. The preset stop time can be set based on actual conditions, and this embodiment does not impose a specific limitation on it. For example, the preset stop time can be less than the idle time in the display device. Idle time refers to the period when the display device is in Blank (blank period). In this embodiment, the voltage drive module 210 can be reset after the display device enters Blank, thereby resetting the timing controller 200 without affecting the user's normal use of the display device. When the 3.3V, 1.8V, and 0.9V voltages restart, all outputs of timing controller 200 will be reset, thereby achieving electrostatic repair of timing controller 200. For example, all control signals output by the timing output module 230 in the timing controller 200 will be reset and reset. In this embodiment, the timing output module 230 can be a crystal oscillator.

[0052] This embodiment performs electrostatic monitoring and repair on the timing controller 200, thereby preventing the timing controller 200 from malfunctioning due to electrostatic discharge and ensuring the reliability of the display device.

[0053] In one feasible embodiment, please refer to Figure 4 The timing controller 200 further includes a timing reset unit 250, which is connected to the voltage drive module 210. The timer resetter 250 is used to periodically reset the voltage drive module 210 according to a preset reset cycle.

[0054] It should be noted that the timer reset device 250 is connected to the voltage drive module 210, and also to the timing output module 230 and the third electrostatic discharge (ESD) detection module 320. The voltage drive module 210 provides voltage to the timer reset device 250, and the timer reset device 250 can monitor the output of the timing output module 230 to detect how many frames of signal the timing output module 230 has output. The preset reset period can be set based on actual conditions. For example, the preset reset period can be N frames, where N can be a positive integer greater than 1. This embodiment does not specifically limit this. For example, if N is 10 frames, then the timer reset device 250 can periodically reset the voltage drive module 210 when it outputs 10 frames of signal. This periodic reset can eliminate abnormalities caused by ESD accumulation, thereby improving the reliability of the timing controller 200. Because the presence of ESD may not immediately cause abnormalities in the output of the timing output module 230, but multiple ESD accumulations may lead to abnormalities in the output of the timing output module 230, this embodiment allows for periodic resets.

[0055] In this embodiment, the timed reset device 250 can send a timed reset signal to the second electrostatic discharge (ESD) detection module 220. The second ESD detection module 220 can then send the timed reset signal to the voltage drive module 210. Upon receiving the timed reset signal, the voltage drive module 210 can restart to achieve a reset. Furthermore, this embodiment performs the reset when the display device is in a Blank period, thus avoiding disruption to normal user operation. Therefore, this embodiment allows for timed resets without affecting user operation, thereby improving the user experience.

[0056] In one feasible embodiment, please refer to Figure 5 The third electrostatic detection module 320 includes a phase detection unit 331 and a voltage detection unit 332, and the drive reset module 330 includes a first adjustment unit 321 and a second adjustment unit 322. The detection terminals of the phase detection unit 331 and the voltage detection unit 332 are both connected to the output terminal of the differential output module 310. The output terminal of the phase detection unit 331 is connected to the input terminal of the first adjustment unit 321. The output terminal of the voltage detection unit 332 is connected to the adjustment feedback terminal of the voltage module. The input terminal of the second adjustment unit 322 is connected to the adjustment control terminal of the voltage module. The output terminals of the first adjustment unit 321 and the second adjustment unit 322 are both connected to the input terminal of the differential output module 310.

[0057] It should be noted that the phase detection unit 331 can be used to detect the phase difference of the differential signal output by the differential output module 310, and the voltage detection unit 332 can be used to detect the common-mode voltage of the differential signal output by the differential output module 310. The first adjustment unit 321 is used to adjust the phase difference of the differential signal, and the second adjustment unit 322 can be used to adjust the common-mode voltage of the differential signal.

[0058] The detection terminals of the phase detection unit 331 and the voltage detection unit 332 are both connected to the output terminal of the differential output module 310, which facilitates the phase detection unit 331 to detect the phase difference of the differential signal and the voltage detection unit 332 to detect the common-mode voltage of the differential signal.

[0059] The output terminals of both the first adjustment unit 321 and the second adjustment unit 322 are connected to the input terminal of the differential output module 310. This facilitates the first adjustment unit 321 in adjusting the phase difference of the differential signal output by the differential output module 310, and also facilitates the second adjustment unit 322 in adjusting the common-mode voltage of the differential signal output by the differential output module 310. Figure 5 In the intermediate voltage module, the port connected to the second regulating unit is the regulating control terminal, and in the voltage module, the port connected to the voltage detection unit is the regulating feedback terminal. The regulating control terminal can be the output voltage port in the voltage module; this embodiment does not specifically limit this.

[0060] In this embodiment, the phase difference of the differential signal can be detected, as well as the common-mode voltage. This facilitates the detection of electrostatic abnormalities in the differential output module 310 by detecting the phase difference and common-mode voltage, so that the second adjustment unit 322 and / or the second adjustment unit 322 can adjust the differential signal output by the differential output module 310 in a timely manner.

[0061] In a feasible embodiment, the phase detection unit 331 is used to detect the phase difference between the positive signal and the negative signal in the differential signal output by the differential output module 310, and to determine that the differential output module 310 has a phase abnormality when the phase difference is not within the preset normal phase range. When the differential output module 310 has a phase abnormality, the phase detection unit 331 outputs a phase adjustment signal to the first adjustment unit 321, and the first adjustment unit 321 gradually increases the phase difference of the differential signal until the phase difference is within a preset normal phase range.

[0062] It should be noted that the differential signal includes a pair of positive and negative signals. When the output of the differential output module 310 is normal, there will also be a phase difference between the positive and negative signals in the differential signal, but this phase difference is within the preset normal phase range.

[0063] The preset normal phase range can be set based on actual conditions. This embodiment does not specify a particular setting. The preset normal phase range can be obtained through testing. For example, the preset normal phase range may include a preset upper limit phase difference and a preset lower limit phase difference. If the preset upper limit phase difference is greater than the preset lower limit phase difference, and the line output by the differential output module 310 for the positive signal is different from the line outputting the negative signal, the impedance can be increased on either the positive or negative signal line until the display screen becomes abnormal. During the process of increasing the impedance, the phase difference corresponding to the impedance that causes the display screen to become abnormal is taken as the preset upper limit phase difference. Similarly, the impedance can be decreased until the display screen becomes abnormal. During the process of decreasing the impedance, the phase difference corresponding to the impedance that causes the display screen to become abnormal is taken as the preset lower limit phase difference. A higher impedance results in a faster signal transmission speed, and thus, by adjusting the impedance, the phase difference can be adjusted. Therefore, in this embodiment, the preset normal phase range can be determined by adjusting the impedance.

[0064] The phase detection unit 331 can detect the phase difference between the positive and negative signals in the differential signal. When the phase difference is not within the preset normal phase range, it is determined that the differential output module 310 has a phase abnormality. In the case of a phase abnormality in the differential output module 310, the phase detection unit 331 can output a phase adjustment signal to the first adjustment unit 321. The first adjustment unit 321 can be a register inside the driver 300. After receiving the adjustment signal, the first adjustment unit 321 can gradually increase the phase difference of the differential signal until the phase difference is within the preset normal phase range. For example, the first adjustment unit 321 internally stores a preset gear phase mapping relationship, which includes multiple adjustment gears and the gear phase difference corresponding to each adjustment gear.

[0065] Before adjusting the phase difference of the differential signal, the differential output module 310 also outputs the differential signal according to the target phase difference corresponding to the target gear. The target gear can be predetermined, and this embodiment does not specifically limit it. After a phase anomaly occurs, the first adjustment unit 321 can adjust from the target gear based on the preset gear phase influence relationship until the phase difference is within the preset normal phase range. When a phase anomaly occurs, the phase difference is generally greater than the preset upper limit phase difference. Therefore, in this embodiment, the adjustment gear can be gradually adjusted from the target gear to gradually reduce the phase difference of the differential signal until the phase difference is within the preset normal phase range. Then, the adjustment gear can be stopped, and the first adjustment unit 321 can update the target gear to an adjustment gear that makes the phase difference within the preset normal phase range. This can eliminate the phase anomaly caused by static electricity, thereby facilitating the static electricity repair of the driver 300.

[0066] In one feasible embodiment, please refer to Figure 6 The second adjustment unit 322 further includes at least two resistors connected in series, wherein the first end of the first resistor R1 in the at least two resistors connected in series is used as the input end of the second adjustment unit, and the second end of the first resistor R1 is used as the output end of the second adjustment unit. The second adjustment unit 322 is used to detect the common-mode voltage of the differential signal output by the differential output module 310. If the common-mode voltage is not within the preset normal common-mode range, it is determined that the differential output module 310 has a voltage abnormality. When the differential output module 310 has a voltage abnormality, the second adjustment unit 322 outputs a voltage adjustment signal to the voltage module 120, and the voltage module 120 gradually adjusts the voltage output to the second adjustment unit until the common mode voltage is within the preset normal common mode range.

[0067] It should be noted that the second adjustment unit 322 can be a register inside the driver 300, and the register corresponding to the second adjustment unit 322 is different from that of the first adjustment unit 321. The second adjustment unit includes at least two resistors connected in series. Taking the second adjustment unit including two resistors connected in series as an example, the two resistors connected in series are the first resistor R1 and the second resistor R2. The input terminal of the second adjustment unit is the first terminal of the first resistor, and the output terminal of the second adjustment unit can be the connection point between the first resistor and the second resistor. The output terminal of the second adjustment unit is equivalent to the voltage divider terminal, which can be considered as the second terminal of the first resistor. The first terminal of the second resistor is connected to the second terminal of the first resistor, and the second terminal of the second resistor is grounded.

[0068] The voltage detection unit 332 can detect the common-mode voltage of the differential signal output by the differential output module 310. The common-mode voltage of the differential signal can be the sum of the voltages of the positive and negative signals in the differential signal. When the common-mode voltage is not within the preset normal common-mode range, it also indicates that the differential output module 310 has a voltage abnormality. The abnormal common-mode voltage is actually caused by the phase difference not being within the preset normal phase range, because different phase differences will result in different common-mode voltages.

[0069] This embodiment improves the reliability of the differential output module 310 by detecting whether the common-mode voltage is abnormal. When an abnormal common-mode voltage is detected, the voltage detection unit 332 can output a voltage adjustment signal to the voltage module 120. This voltage adjustment signal reflects the abnormality of the common-mode voltage and can be a low-level signal; this embodiment does not specifically limit its application.

[0070] The voltage module 120 can gradually adjust the voltage output to the second adjustment unit until the common-mode voltage is within a preset normal common-mode range. The preset normal common-mode range can be set based on actual conditions, and this embodiment does not impose a specific limitation on it. For example, the preset normal common-mode range can be 0.3V~0.7V. When the voltage input to the second adjustment unit changes, the voltage at the voltage divider terminal of the second adjustment unit will also change. The voltage divider terminal of the second adjustment unit can be connected to the input terminal of the differential output module 310, and the voltage at the voltage divider terminal can be accumulated onto the common-mode voltage of the differential signal output by the differential output module 310, thereby restoring the common-mode voltage to normal and eliminating the abnormality caused by static electricity.

[0071] In this embodiment, the output of the differential output module 310 can be restored to normal by adjusting the phase difference and / or common-mode voltage, thereby achieving electrostatic repair of the driver 300 and improving the reliability of the display device.

[0072] In one feasible embodiment, please refer to Figure 7 The display device also includes a device control module 400. The detection feedback terminal D1 of the device control module 400 is connected to the first electrostatic detection module 130, the second electrostatic detection module 220 and the third electrostatic detection module 320. The priority control terminal D2 of the device control module 400 is also connected to the power reset module 110, the second electrostatic detection module 220 and the drive reset module 330. The device control module 400 is used to perform a reset instruction operation according to a preset repair priority when the first electrostatic detection module 130 detects an abnormality in the output of the voltage module 120, the second electrostatic detection module 220 detects an abnormality in the output of the timing output module 230, and / or the third electrostatic detection module 320 detects an abnormality in the output of the differential output module 310. The reset indication operation includes: when there are at least two abnormal modules, determining the target abnormal module with the highest reset priority among the at least two abnormal modules, sending a reset indication signal to the reset control module corresponding to the target abnormal module to reset the target abnormal module; after the target abnormal module is reset, if there are still remaining abnormal modules with output abnormalities among the at least two abnormal modules, then sending a reset indication signal to the reset control module corresponding to the remaining abnormal modules. The preset repair priorities include: the reset priority of the voltage module 120 is higher than the reset priority of the voltage drive module 210, and the reset priority of the voltage drive module 210 is higher than the reset priority of the differential output module 310. The abnormal module is a voltage module 120, a timing output module 230 or a differential output module 310. The at least two abnormal modules are different, and the remaining abnormal module is a timing output module 230 or a differential output module 310. The reset control module corresponding to the voltage module 120 is the power reset module 110, the reset control module corresponding to the timing output module 230 is the second electrostatic detection module 220, and the reset module corresponding to the differential output module 310 is the drive reset module 330.

[0073] It should be noted that the device control module 400 can be the SOC in the display device. In this embodiment, the device control module 400 can also control the repair priority. Specifically, the detection feedback terminal D1 of the device control module 400 can be connected to the first electrostatic discharge (ESD) detection module 130, the second ESD detection module 220, and the third ESD detection module 320. This allows the device control module 400 to receive voltage anomaly signals generated by the first ESD detection module 130, timing anomaly signals generated by the second ESD detection module 220, and phase and voltage anomaly signals detected by the third ESD detection module 320. Based on a preset repair priority, the repair priority of the voltage module 120, voltage drive module 210, and differential output module 310 can be controlled.

[0074] The priority control terminal D2 of the device control module 400 is also connected to the power reset module 110, the second electrostatic detection module 220 and the drive reset module 330, which also facilitates the device control module 400 to control the repair priority of the voltage module 120, the voltage drive module 210 and the differential output module 310.

[0075] Reference Figure 7 The port of the first electrostatic discharge (ESD) detection module 130 that outputs a voltage abnormality signal is connected to the detection feedback terminal D1. The port of the second ESD detection module 220 that outputs a timing abnormality signal is also connected to the detection feedback terminal D1. The third ESD detection module 320, upon detecting a phase difference and / or common-mode voltage abnormality, will also output a drive abnormality signal. The port of the third ESD detection module 320 that outputs the drive abnormality signal is connected to the detection feedback terminal D1. The drive abnormality signal can reflect the phase difference and / or common-mode voltage abnormality of the differential output module 310. The priority control terminal D2 in the device control module 400 is connected to the reset start terminal of the power reset module 110, the reset start terminal of the drive reset module 330, and the reset start terminal of the second ESD detection module 220.

[0076] In this embodiment, if the first electrostatic discharge (ESD) detection module 130, the second ESD detection module 220, the third ESD detection module 320, the power reset module 110, the voltage drive module 210, and the drive reset module 330 are all connected to the device control module 400, the power reset module 110 will reset the voltage module 120 only after receiving a reset indication signal from the device control module 400. In other embodiments, since the power module has the highest reset priority, the voltage module 120 can be reset directly even without receiving a reset indication signal. For the timing controller 200, the second ESD detection module 220 can send a timing error signal to the voltage module 120 only after receiving a reset indication signal, so that the voltage drive module 210 resets only after the second ESD detection module 220 receives the reset indication signal. This allows the device control module 400 to control priorities and improve the reliability of priority control. As for the driver 300, the differential output module 310 can be adjusted after the driver reset module 330 receives the reset indication signal. Specifically, the first adjustment unit 321 can adjust the phase difference after receiving the reset indication signal, and the second adjustment unit 322 can adjust the phase difference after receiving the reset indication signal.

[0077] When there is only one faulty module, the device control module 400 can directly send a reset indication signal to the reset module corresponding to the faulty module, without needing to send a reset indication signal according to the preset repair priority. The reset indication signal is used to indicate that electrostatic repair can be performed.

[0078] In the preset repair priority, the voltage module 120 has the highest reset priority, followed by the voltage drive module 210, and the differential output module 310 has the lowest reset priority. That is, when the voltage module 120, timing output module 230, and differential output module 310 are all abnormal, the voltage module 120 is reset first. After the voltage module 120 is reset, if the timing output module 230 is still abnormal, a reset indication signal is sent to the second electrostatic detection module 220 to reset the voltage drive module 210. Generally, when the voltage module 120 is reset, it is equivalent to resetting the voltage drive module 210 as well. Therefore, after the voltage module 120 is reset, the output of the timing output module 230 usually returns to normal. After both the timing output module 230 and the voltage module 120 are reset, a reset indication signal is sent to the drive reset module 330 to adjust the differential output module 310 and restore it to normal. This improves the reliability of the repair priority control.

[0079] When there are two abnormal modules, namely voltage module 120 and timing output module 230, the device control module 400 first sends a reset indication signal to voltage module 120. After voltage module 120 is reset, the second electrostatic detection module 220 detects whether timing output module 230 is abnormal. If timing output module 230 is not abnormal, then there are no remaining abnormal modules among the two abnormal modules. If timing output module 230 is still abnormal, then the remaining abnormal module is timing output module 230, and a reset indication signal can be sent to the reset control module corresponding to timing output module 230. The reset control module corresponding to timing output module 230 is the second electrostatic detection module 220. This is because for timing controller 200, the second electrostatic detection module 220 sends a timing abnormal signal to voltage module 120, and voltage module 120 directly resets voltage drive module 210. After voltage drive module 210 is reset, timing output module 230 is also equivalent to being reset. Therefore, the reset control module corresponding to timing output module 230 can be the second electrostatic detection module 220.

[0080] When there are two abnormal modules, namely voltage module 120 and differential output module 310, the device control module 400 first sends a reset indication signal to voltage module 120. After voltage module 120 is reset, the third electrostatic detection module 320 detects whether differential output module 310 is still abnormal. If differential output module 310 is not abnormal, then there are no remaining abnormal modules among the two abnormal modules. If differential output module 310 is still abnormal, then the remaining abnormal module is differential output module 310, and a reset indication signal can be sent to the reset control module corresponding to differential output module 310. The reset control module corresponding to differential output module 310 is drive reset module 330.

[0081] When there are two abnormal modules, namely timing output module 230 and differential output module 310, the device control module 400 first sends a reset indication signal from voltage module 120 to second electrostatic detection module 220. After voltage drive module 210 is reset, the third electrostatic detection module 320 checks whether differential output module 310 is still abnormal. If differential output module 310 is not abnormal, then there are no remaining abnormal modules among the two abnormal modules. If differential output module 310 is still abnormal, then the remaining abnormal module is differential output module 310, and a reset indication signal can be sent to the reset control module corresponding to differential output module 310. The reset control module corresponding to differential output module 310 is drive reset module 330.

[0082] This embodiment can improve the reliability of repair priority control through the device control module 400.

[0083] In one feasible embodiment, please refer to Figure 8 The reset control terminal D3 of the device control module 400 is connected to the abnormal feedback terminal of the power reset module 110 and the drive feedback terminal of the voltage drive module 210. When the device control module 400 detects that the abnormal feedback terminal is at a low level and / or the drive feedback terminal is at a preset medium level, the device control module 400 controls the display device to restart, so as to reset the voltage module 120 and the voltage drive module 210.

[0084] It should be noted that the device control module 400 also includes a reset control terminal D3. The reset control terminal D3 can be connected to the abnormal feedback terminal of the power reset module 110. The abnormal feedback terminal of the power reset module 110 is at a high level when the voltage module 120 can output normally, and at a low level when the voltage module 120 does not output within a preset detection time. (Refer to...) Figure 8 , Figure 8 The port of the power driver connected to the reset control terminal D3 is the drive feedback terminal, and the port of the power reset module 110 connected to the reset control terminal D3 is the abnormal feedback terminal.

[0085] Because one possibility is that an ESD shock could directly cause PMIC malfunction, preventing it from outputting any signal, this embodiment includes an abnormal feedback terminal on the power reset module 110. This abnormal feedback terminal can be connected to the reset control terminal D3 in the device control module 400 via an FFC (Flat Flexible Cable) wire. When the control module detects a low level at the abnormal feedback terminal, the device control module 400 initiates a power restart, which in turn restarts the display device, thereby resetting both the power manager 100 and the timing controller 200. The preset detection duration can be set based on actual conditions; this embodiment does not impose a specific limitation on it.

[0086] Furthermore, in this embodiment, the voltage module 120 is reset after the timing controller 200 sends a power reset signal to the power reset module 110. Therefore, in this embodiment, the reset of the voltage module 120 depends on the timing controller 200. If the timing output module 230 in the timing controller 200 is not abnormal, the voltage module 120 can be reset by the power reset signal output by the timing controller 200. If the timing output module 230 in the timing controller 200 is also abnormal, the voltage module 120 may not be reset by the power reset signal sent by the timing controller 200. Therefore, in this embodiment, a drive feedback terminal is provided on the voltage drive module 210, and the drive feedback terminal is connected to the reset control terminal D3. When the device control module 400 detects that the drive feedback terminal is at a preset level, the device control module 400 will also control the display device to restart to perform a reset, thereby improving the reliability of the reset.

[0087] The preset level can be set based on the actual situation. This embodiment does not make a specific limitation on this. In the timing controller 200, when the timing controller 200 is subjected to electrostatic interference, the voltage output of the voltage drive module 210 may decrease. Since the voltage drive module 210 needs time to power down, the voltage output of the voltage drive module 210 will not drop to 0 immediately when there is electrostatic interference. Therefore, in this embodiment, the display device is restarted when the preset level is set at the drive feedback terminal, thereby improving the efficiency of electrostatic repair and improving the reliability of electrostatic repair.
