[0048] For the purpose of clarity, technical solutions and advantages of the present application will be further described in detail below with reference to the accompanying drawings.

[0049] The example embodiments will be described in detail herein with reference to the accompanying drawings. The following description is with reference to the drawings, in which like numerals indicate like elements, and different drawings might have different numbers of the same element. The following example embodiments described are not meant to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0050] The terminology used in the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. As used in the present application and the appended claims, the singular forms "a," "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and / or "comprising," when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0051] It should be noted that the object information (including but not limited to object device information, object personal information, etc.) and data (including but not limited to data for analysis, stored data, displayed data, etc.) involved in the present application are all information and data authorized by the object or fully authorized by all parties, and the collection, use and processing of related data need to comply with relevant laws, regulations and standards of relevant countries and regions.

[0052] It should be understood that, although the terms first, second, etc. can be used herein to describe various information, these information should not be limited to these terms. These terms are only used to differentiate one piece of information from another piece of information. For example, a first parameter can also be referred to as a second parameter, and similarly, a second parameter can also be referred to as a first parameter without departing from the scope of the present application. Depending on the context, the word "if' as used herein can be interpreted as "when" or "upon" or "in response to determining".

[0053] First, some terms involved in the present application are explained:

[0054] Electricity compensation: a method of improving picture quality by extracting electrical characteristic data in a power system, adjusting the electrical characteristic data after calculation, and adjusting the voltage in the present application.

[0055] In the pixel circuit of an organic light emitting diode (OLED), at least two thin film transistors (TFTs) are needed for driving. The TFTs are usually selected from low temperature poly-silicon (LTPS) TFTs or metal oxide TFTs; among them, LTPS TFTs are generally suitable for small size OLED displays because they have higher mobility and smaller device area, and are more suitable for high pixel density unit display applications. Metal oxide TFTs are generally used for large size OLED displays because of their good uniformity.

[0056] However, both have disadvantages. Producing LTPS TFTs on a large area glass substrate, TFTs at different positions will have differences in some electrical parameters, such as threshold voltage, mobility, etc., which will cause uneven brightness problems. Under the influence of long time pressure and temperature rise, the threshold voltage of metal oxide TFT will also drift, resulting in residual image problems.

[0057] FIG. 1 shows a schematic diagram of a display device 100 according to an example embodiment of the present application. The display device 100 includes a system chip 101, a timing controller 102, and a display panel 103.

[0058] The display panel 103 in the embodiments of the present application includes various display panels, which can be selected and arranged according to actual needs. For example, the display panel 103 can be an OLED display panel, a quantum dot light emitting diode (QLED) display panel, or a micro light emitting diode (Micro LED) display panel, etc., which is not limited in the embodiments of the present application, and the embodiments of the present application are usually exemplified by taking the OLED display panel as an example.

[0059] For the display panel 103, in order to ensure its display effect, the above problems are solved by using an electrical compensation technology. The electrical compensation is to transmit the current-voltage characteristics of the TFT and the current-voltage characteristics of the OLED in the pixel to the sensing circuit (not shown in FIG. 1) through the TFT, calculate the voltage value to be compensated, and feed back to the system chip 101 to realize the electrical compensation. This part of work can be completed by the timing controller (TCON) 102, which provides the calculated compensation voltage to each pixel in a row-by-row or column-by-column manner for compensation, so that the display signal does not need to be provided by the system chip (SoC) 101 during the compensation process. However, the system chip 101 and the power supply are still working normally to ensure that the overall system is in an open state during the compensation process, and the communication between the system chip 101 and the timing controller 102 is also normal. For example, after the electrical compensation is completed, the timing controller 102 sends an end signal to the system chip 101.

[0060] In the electrical compensation process of the related art, the timing controller 102 controls the display panel 103 to display a full black screen and compensates each pixel. Taking the OLED display panel as an example, the electrical compensation process lasts about 10 minutes. After the electrical compensation is completed, the system chip 101 receives the end signal and performs a shutdown operation. If the electrical compensation is unsuccessful and is not completed within 10 minutes, the system chip 101 will perform a shutdown operation based on the upper limit of the preset compensation time, for example, 25 minutes.

[0061] The electrical compensation needs a long execution time. Moreover, if the user issues other instructions to the OLED display panel during the electrical compensation, the OLED display panel needs to wait until the electrical compensation is completed before responding to the other instructions.

[0062] In order to solve the above problems, the present application provides a display device 100, and FIG. 2 shows a schematic diagram of the display device 100 and the control device 110 provided by an exemplary embodiment of the present application, which includes a system chip 101, a timing controller 102, and a display panel 103.

[0063] In some embodiments, the system chip 101 is configured to detect an interrupt signal during the electrical compensation performed by the timing controller 102 on the display panel 103, the interrupt signal being configured to indicate interrupting the electrical compensation; the system chip 101 is configured to send the interrupt signal to the timing controller 102 in response to receiving the interrupt signal; and the timing controller 102 is configured to interrupt the electrical compensation according to the interrupt signal.

[0064] When the display device 100 is in a sense compensation state, the system chip 101 detects the interrupt signal. The display device 100 in the sense compensation state is in a state that the timing controller 102 performs the electrical compensation, and the system chip 101 detects the interrupt signal. In the embodiments of the present application, the words of sense, detect, sense, check and the like have the same meaning, and are generally described by taking detection as an example. That is, the display device 100 in the sense compensation state can be understood as that the timing controller 102 in the display device 100 performs the electrical compensation, and the system chip 101 detects the interrupt signal at the same time.

[0065] Optionally, the interrupt signal is sent by the control device 110, for example, a user clicks a power key on a remote controller, and the remote controller sends the interrupt signal.

[0066] The system chip 101 is configured to send the interrupt signal to the timing controller 102.

[0067] In some embodiments, the system chip 101 is configured to send the interrupt signal to the timing controller 102 in response to receiving the interrupt signal sent by the control device 110; and the control device 110 is configured to control the display device 100.

[0068] For example, the control device 110 includes at least one of the following: a remote controller, a smart phone, a touch screen control device, a gesture control device, and a physical key control device. The embodiments of the present application are generally described by taking the remote controller as an example, and the control device 110 is not limited.

[0069] In the case that the control device 110 is a remote controller, the remote controller sends the interrupt signal in response to a control key on the remote controller being clicked. For example, the control key includes at least one of the following: a power key, a confirmation key, a return key, and a home key. The control key can also be any other key on the remote controller, and the embodiments of the present application are not limited in this regard.

[0070] Optionally, the system chip 101 is configured to, in response to receiving the interrupt signal sent by the control device 110, generate a prompt signal, and send the prompt signal to the display panel 103; the display panel 103 is configured to display a prompt control according to the prompt signal, the prompt control being used for prompting the user to confirm whether to interrupt the electrical compensation; in a case where the electrical compensation is confirmed to be interrupted, the system chip 101 is configured to receive a confirmation signal sent by the control device 110; and the system chip 101 is configured to, in response to receiving the confirmation signal, send the interrupt signal to the timing controller 102.

[0071] After receiving the interrupt signal, the system chip 101 does not immediately send the interrupt signal to the timing controller 102, but generates a prompt signal and sends the prompt signal to the display panel 103. After receiving the prompt signal, the display panel 103 displays a prompt control, for example, a prompt window including “whether to interrupt the electrical compensation” and a confirmation button and a cancel button.

[0072] In a case where the user clicks the confirmation button through the control device 110, the control device 110 is configured to send a confirmation signal to the system chip 101. In a case where the system chip 101 receives the confirmation signal, the system chip 101 sends the interrupt signal to the timing controller 102.

[0073] In a case where the user clicks the cancel button through the control device 110, the control device 110 is configured to send a cancel signal to the system chip 101. In a case where the system chip 101 receives the cancel signal or does not receive the confirmation signal, the system chip 101 does not send the interrupt signal to the timing controller 102.

[0074] After the electrical compensation is interrupted, the display panel 103 displays a picture or shuts down:

[0075] In some embodiments, the timing controller 102 is configured to, after the electrical compensation is interrupted, control the display panel to display a picture using historical compensation voltage data; wherein the historical compensation voltage data is compensation voltage data before the present electrical compensation.

[0076] Optionally, the historical compensation voltage data is stored in the timing controller 102.

[0077] In a case where the electrical compensation is performed for multiple times, the historical compensation voltage data is stored in the timing controller 102, and the historical compensation voltage data includes a voltage value required for compensation of each pixel in a certain electrical compensation before the present electrical compensation.

[0078] By way of example and not limitation, the historical compensation voltage data includes at least one of the following: compensation voltage data of a previous electrical compensation; and pre-set compensation voltage data.

[0079] In some embodiments, when the current electrical compensation is not the first electrical compensation, the compensation voltage data of the previous electrical compensation is used as the historical compensation voltage data; when the current electrical compensation is the first electrical compensation, the preset compensation voltage data is used as the historical compensation voltage data.

[0080] In some embodiments, the timing controller 102 is configured to control the display panel to shut down after the electrical compensation is interrupted.

[0081] In order to save energy, the display panel is controlled to shut down after the electrical compensation is interrupted, and the screen is not re-displayed.

[0082] The electrical compensation process includes:

[0083] In some embodiments, the system chip 101 is configured to send a compensation signal to the timing controller 102; the timing controller 102 is configured to perform electrical compensation on the display panel 103 upon receiving the compensation signal, and the compensation signal is used to instruct the timing controller 102 to perform electrical compensation.

[0084] In some embodiments, the system chip 101 is configured to generate a compensation signal when a compensation condition is met, and send the compensation signal to the timing controller 102.

[0085] For example, the compensation condition includes at least one of the following:

[0086] • receiving a shutdown signal and the use time of the display panel 103 being greater than a first time threshold;

[0087] • receiving a control signal sent by the control device 110;

[0088] • the use time of the display panel 103 being greater than a second time threshold;

[0089] • a compensation control on the display panel 103 being clicked.

[0090] The second time threshold is greater than the first time threshold, for example, the second time threshold is 48 hours and the first time threshold is 4 hours.

[0091] The compensation condition can be preset, and the present application does not limit it, as long as the compensation condition is met, the system chip 101 can generate a compensation signal. For example, the display panel 103 includes a compensation control for starting the compensation function. When the user selects to start the compensation function by clicking the compensation control, the timing controller 102 performs electrical compensation. For another example, the electrical compensation is automatically performed every time the display panel 103 is shut down.

[0092] (1) In some embodiments, the system chip 101 is configured to send a compensation signal to the timing controller 102 when a shutdown signal is received and the usage time of the display panel 103 is greater than a first time threshold.

[0093] Generally, the first time threshold is a small threshold. If the usage time of the display panel 103 is less than or equal to the first time threshold when the system chip 101 receives the shutdown signal, the system chip 101 does not send the compensation signal to the timing controller 102.

[0094] For example, when the first time threshold is 4 hours and the usage time of the display panel 103 is 10 minutes, even if the display panel 103 receives the shutdown signal, the system chip 101 does not send the compensation signal to the timing controller 102, because the usage time is short and the display effect of the display panel 103 is not affected, and no electrical compensation needs to be performed.

[0095] (2) In some embodiments, the system chip 101 is configured to send a compensation signal to the timing controller 102 when a control signal sent by the control device 110 is received; wherein the control signal is used to instruct the timing controller 102 to perform electrical compensation on the display panel 103.

[0096] For example, when the compensation button on the control device 110 is clicked, the control device 110 sends the control signal; or when the display panel 103 displays “whether to perform electrical compensation”, the user clicks the confirmation button on the control device, and the control device 110 sends the control signal.

[0097] (3) In some embodiments, the system chip 101 is configured to send a compensation signal to the timing controller 102 when the usage time of the display panel 103 is greater than a second time threshold.

[0098] Generally, the second time threshold is a large threshold. For example, when the second time threshold is 48 hours, the system chip 101 sends the compensation signal to the timing controller 102 when the usage time of the display panel 103 is greater than 48 hours, and the timing controller 102 performs electrical compensation. In this case, the display panel can be protected and the service life of the display panel can be extended.

[0099] (4) In some embodiments, the system chip 101 is configured to send a compensation signal to the timing controller 102 when a compensation control on the display panel 103 is clicked.

[0100] For example, the control device 110 sends an indication signal to indicate whether the compensation control is clicked. In the case that the control device 110 sends the indication signal corresponding to the determination, the compensation control is clicked, and the system chip 101 sends a compensation signal to the timing controller 102.

[0101] For another example, the display panel 103 is a touch screen, and in the case that the compensation control on the display panel 103 is clicked, the system chip 101 sends a compensation signal to the timing controller 102.

[0102] Optionally, the system chip 101 is configured to control the display panel 103 to display the compensation control in the case that the usage time of the display panel 103 is greater than or equal to a third time threshold.

[0103] Generally, the third time threshold is a relatively large threshold. For example, the third time threshold is 24 hours, and in the case that the usage time of the display panel 103 is equal to 24 hours, the system chip 101 controls the display panel 103 to display the compensation control, and the compensation control includes "whether to perform electrical compensation" and confirmation control and cancellation control.

[0104] Suppose that the user chooses not to perform electrical compensation after the display panel 103 displays the compensation control for the first time, then the system chip 101 can control the display panel 103 to no longer display the compensation control, or periodically control the display panel 103 to display the compensation control. For example, in the case that the usage time of the display panel 103 is greater than 24 hours, the system chip 101 controls the display panel 103 to display the compensation control once every 2 hours.

[0105] In summary, the device provided in the embodiment can interrupt the electrical compensation during the electrical compensation performed by the timing controller, the system chip detects the interrupt signal, and when the system chip receives the interrupt signal, the system chip forwards the interrupt signal to the timing controller, and the timing controller interrupts the electrical compensation, so that the interrupt can be performed during the electrical compensation, and the problem that the display panel can only respond to other instructions after the electrical compensation is completed is avoided, and the flexibility of the electrical compensation is improved.

[0106] The device provided in the embodiment can also display the picture according to the historical compensation voltage data by the display panel after the electrical compensation is interrupted, so as to reduce the influence of the electrical compensation interruption on the picture, meet the demand of the user that the electrical compensation is not needed at present and the picture needs to be continuously watched, or turn off the display device by the display panel after the electrical compensation is interrupted, so as to save the energy consumption of the display device.

[0107] FIG. 3 shows a flowchart of a compensation interruption method provided in an example embodiment of the present application, the method is performed by a display device 100, the display device 100 includes a system chip 101, a timing controller 102 and a display panel 103, and the method includes at least one of the following steps.

[0108] Step 310: The timing controller 102 performs electrical compensation on the display panel 103.

[0109] In some embodiments, in order to ensure the display effect of the display panel 103, electrical compensation is performed.

[0110] The electrical compensation is achieved by transmitting the current-voltage characteristics of the TFT inside the pixel to the sensing circuit (not shown in FIG. 1), calculating the voltage value that needs to be compensated, and feeding back to the system chip 101. This part of work can be completed by the timing controller 102, which provides the calculated compensation voltage to each pixel in a row-by-row or column-by-column manner for compensation, so that the display signal is not required from the system chip 101 during the compensation process. However, the system chip 101 and the power supply are still working normally, ensuring that the overall system is in an open state during the compensation process, and the communication between the system chip 101 and the timing controller 102 is also normal. For example, after the electrical compensation is completed, the timing controller 102 sends an end signal to the system chip 101.

[0111] During the electrical compensation process, the timing controller 102 controls the display panel 103 to display a full black screen and compensates each pixel. Taking an OLED display panel as an example, the electrical compensation process lasts about 10 minutes. After the electrical compensation is completed, the system chip 101 receives the end signal and performs a shutdown operation. If the electrical compensation is unsuccessful and has not been completed for more than 10 minutes, the system chip 101 will perform a shutdown operation based on the upper limit of the pre-set compensation time, for example, 25 minutes.

[0112] Step 320: The system chip 101 detects an interrupt signal.

[0113] The system chip 101 detects an interrupt signal during the electrical compensation performed by the timing controller 102 on the display panel 103. The interrupt signal is used to indicate interrupting the electrical compensation.

[0114] Step 330: The system chip 101 sends the interrupt signal to the timing controller 102.

[0115] In response to receiving the interrupt signal, the system chip 101 sends the interrupt signal to the timing controller 102.

[0116] The interrupt signal is used to indicate interrupting the electrical compensation, which is performed by the timing controller 102. After receiving the interrupt signal, the system chip 101 forwards it to the timing controller 102.

[0117] Step 340: The timing controller 102 interrupts the electrical compensation.

[0118] The timing controller 102 is configured to control the execution or interruption of the electrical compensation. In the case of receiving the interruption signal, the timing controller 102 interrupts the electrical compensation according to the interruption signal.

[0119] In summary, the method provided by the embodiment can interrupt the electrical compensation during the execution of the electrical compensation by the timing controller, the system chip detects the interruption signal, and forwards the interruption signal to the timing controller after receiving the interruption signal, and the timing controller interrupts the electrical compensation, so that the interruption can be made during the electrical compensation, and the problem that the display panel can only respond to other instructions after the electrical compensation is completed is avoided, and the flexibility of the electrical compensation is improved.

[0120] FIG. 4 shows a flowchart of a compensation interruption method provided by an example embodiment of the present application, which is executed by a display device 100 and a control device 110, the display device 100 comprising a system chip 101, a timing controller 102 and a display panel 103, and the method comprises at least one of the following steps.

[0121] Step 310: The timing controller 102 executes the electrical compensation on the display panel 103.

[0122] Step 320: The system chip 101 detects an interruption signal.

[0123] Step 329: The control device 110 sends the interruption signal to the system chip 101.

[0124] For example, the control device 110 comprises at least one of the following: a remote controller, a smart phone, a touch screen control device, a gesture control device and a physical key control device. The embodiments of the present application are generally described by taking the remote controller as an example, and the control device 110 is not limited.

[0125] In the case of the control device 110 being the remote controller, the remote controller sends the interruption signal in response to a control key on the remote controller being clicked. For example, the control key comprises at least one of the following: a power key, a confirmation key, a back key and a home key.

[0126] Step 330: The system chip 101 sends the interruption signal to the timing controller 102.

[0127] In some embodiments, in response to receiving the interruption signal sent by the control device 110, the system chip 101 sends the interruption signal to the timing controller 102; wherein the control device 110 is configured to control the display device 100.

[0128] Optionally, the system chip 101 generates a prompt signal in response to receiving the interrupt signal sent by the control device 110, and sends the prompt signal to the display panel 103; the display panel 103 displays a prompt control according to the prompt signal, the prompt control being used for prompting the user to confirm whether to interrupt the electrical compensation; in the case of confirming to interrupt the electrical compensation, the system chip 101 receives a confirmation signal sent by the control device 110; the system chip 101 sends the interrupt signal to the timing controller 102 in response to receiving the confirmation signal.

[0129] After receiving the interrupt signal, the system chip 101 does not immediately send the interrupt signal to the timing controller 102, but generates a prompt signal and sends the prompt signal to the display panel 103. After receiving the prompt signal, the display panel 103 displays a prompt control, for example, a prompt window, including “whether to interrupt the electrical compensation” and a confirmation button and a cancel button.

[0130] In the case of the user clicking the confirmation button through the control device 110, the control device 110 sends a confirmation signal to the system chip 101. The system chip 101 sends the interrupt signal to the timing controller 102 in the case of receiving the confirmation signal.

[0131] In the case of the user clicking the cancel button through the control device 110, the control device 110 sends a cancel signal to the system chip 101. The system chip 101 does not send the interrupt signal to the timing controller 102 in the case of receiving the cancel signal or not receiving the confirmation signal.

[0132] Step 340: The timing controller 102 interrupts the electrical compensation.

[0133] In summary, the method provided by the embodiment is simple and convenient to realize, and is beneficial for the user to interrupt the electrical compensation at any time during the electrical compensation without a complicated operation process, by the system chip sending the interrupt signal to the timing controller in response to receiving the interrupt signal sent by the control device, and the display device being controlled by the control device such as a remote controller.

[0134] FIG. 5 shows a flowchart of a compensation interrupting method provided by an example embodiment of the application, the method being executed by a display device 100, the display device 100 including a system chip 101, a timing controller 102 and a display panel 103, and the method further including the following steps compared with the embodiment of FIG. 3.

[0135] Step 350: The timing controller 102 controls the display panel 103 to display a picture or to shut down.

[0136] In some embodiments, after the interruption of the electrical compensation, the timing controller 102 controls the display panel 103 to display a picture using historical compensation voltage data; wherein the historical compensation voltage data is compensation voltage data before the present electrical compensation.

[0137] Optionally, the historical compensation voltage data is stored in the timing controller 102.

[0138] In the case of multiple executions of the electrical compensation, the historical compensation voltage data is stored in the timing controller 102, and the historical compensation voltage data includes a voltage value that each pixel needs to be compensated in a certain electrical compensation before the present electrical compensation.

[0139] By way of example but not limitation, the historical compensation voltage data includes at least one of the following: compensation voltage data of the previous electrical compensation; pre-set compensation voltage data.

[0140] When the present electrical compensation is not the first electrical compensation, the compensation voltage data of the previous electrical compensation is used as the historical compensation voltage data; when the present electrical compensation is the first electrical compensation, the pre-set compensation voltage data is used as the historical compensation voltage data.

[0141] In some embodiments, after the interruption of the electrical compensation, the timing controller 102 controls the display panel 103 to shut down.

[0142] In order to save energy more, the display panel 103 shuts down after the interruption of the electrical compensation, and does not display a picture again.

[0143] In summary, the method provided by the embodiment reduces the influence of the interruption of the electrical compensation on the picture, meets the requirement of the user that the present electrical compensation is not needed and the picture needs to be continuously watched, or saves the energy consumption of the display device by shutting down the display panel after the interruption of the electrical compensation.

[0144] FIG. 6 shows a flowchart of a compensation interruption method provided by an example embodiment of the present application, which is executed by a display device 100 including a system chip 101, a timing controller 102 and a display panel 103, and includes at least one of the following steps.

[0145] Step 301: The system chip 101 sends a compensation signal to the timing controller 102.

[0146] In some embodiments, before the system chip 101 sends the compensation signal to the timing controller 102, the system chip 101 generates the compensation signal in the case that a compensation condition is met, and the compensation signal is used to instruct the timing controller 102 to execute the electrical compensation.

[0147] Exemplarily, the compensation condition comprises at least one of the following:

[0148] receiving a shutdown signal and the usage duration of the display panel 103 being greater than a first time threshold;

[0149] receiving a control signal sent by the control device 110;

[0150] the usage duration of the display panel 103 being greater than a second time threshold;

[0151] a compensation control on the display panel 103 being clicked.

[0152] The second time threshold is greater than the first time threshold, for example, the second time threshold is 48 hours and the first time threshold is 4 hours.

[0153] The compensation condition can be set in advance, which is not limited in the present application. As long as the compensation condition is met, the system chip 101 can generate a compensation signal. For example, the display panel 103 includes a compensation control for starting the compensation function. When the user selects to start the compensation function by clicking the compensation control, the timing controller 102 performs electrical compensation. For another example, electrical compensation is automatically performed every time the device is shut down.

[0154] (1) In some embodiments, in the case of receiving a shutdown signal and the usage duration of the display panel 103 being greater than a first time threshold, the system chip 101 sends a compensation signal to the timing controller 102; wherein the shutdown signal is used to indicate that the display panel 103 is shut down.

[0155] Generally, the first time threshold is a small threshold. If the system chip 101 receives a shutdown signal and the usage duration of the display panel 103 is less than or equal to the first time threshold, the system chip 101 does not send a compensation signal to the timing controller 102.

[0156] Exemplarily, in the case of the first time threshold being 4 hours and the usage duration of the display panel 103 being 10 minutes, even if the display panel 103 receives a shutdown signal, the system chip 101 does not send a compensation signal to the timing controller 102, because the usage duration is short and the display effect of the display panel 103 is not affected, and electrical compensation is not needed.

[0157] (2) In some embodiments, in the case of receiving a control signal sent by the control device, the system chip 101 sends a compensation signal to the timing controller 102; wherein the control signal is used to instruct the timing controller 102 to perform electrical compensation on the display panel 103.

[0158] For example, the control device 110 sends the control signal when the compensation button on the control device 110 is clicked; or the user clicks the confirmation button on the control device when the display panel 103 displays "whether to perform the electrical compensation", and the control device 110 sends the control signal.

[0159] (3) In some embodiments, the system chip 101 sends the compensation signal to the timing controller 102 when the usage time of the display panel 103 is greater than a second time threshold.

[0160] Generally, the second time threshold is a large threshold. For example, the second time threshold is 48 hours, that is, the system chip 101 sends the compensation signal to the timing controller 102 when the usage time of the display panel 103 is greater than 48 hours, and the timing controller 102 performs the electrical compensation. In this case, the display panel can be protected, and the service life of the display panel can be prolonged.

[0161] (4) In some embodiments, the system chip 101 sends the compensation signal to the timing controller 102 when the compensation control on the display panel 103 is clicked.

[0162] For example, the control device 110 sends the indication signal to indicate whether the compensation control is clicked. When the control device 110 sends the indication signal corresponding to the determination, the compensation control is clicked, and the system chip 101 sends the compensation signal to the timing controller 102.

[0163] For another example, the display panel 103 is a touch screen, and the system chip 101 sends the compensation signal to the timing controller 102 when the compensation control on the display panel 103 is clicked.

[0164] Optionally, the system chip 101 controls the display panel 103 to display the compensation control when the usage time of the display panel 103 is greater than a third time threshold.

[0165] Generally, the third time threshold is a large threshold. For example, the third time threshold is 24 hours, and the system chip 101 controls the display panel 103 to display the compensation control when the usage time of the display panel 103 is equal to 24 hours. The compensation control includes "whether to perform the electrical compensation" and confirmation control and cancellation control.

[0166] Suppose the user chooses not to perform the electrical compensation after the display panel 103 displays the compensation control for the first time, the system chip 101 can control the display panel 103 to no longer display the compensation control, or periodically control the display panel 103 to display the compensation control. For example, the system chip 101 controls the display panel 103 to display the compensation control once every 2 hours when the usage time of the display panel 103 is greater than 24 hours.

[0167] Step 310: The timing controller 102 performs electrical compensation on the display panel 103.

[0168] In some embodiments, the timing controller 102 performs electrical compensation on the display panel 103 in the case that the timing controller 102 receives the compensation signal.

[0169] Step 320: The system chip 101 detects the interrupt signal.

[0170] Step 330: The system chip 101 sends the interrupt signal to the timing controller 102.

[0171] Step 340: The timing controller 102 interrupts the electrical compensation.

[0172] In summary, the method provided by the embodiment, by receiving the shutdown signal, and the use time of the display panel is greater than the first time threshold, the system chip sends the compensation signal to the timing controller, so that the display panel is executed after a certain time of use electrical compensation, thereby improving the picture performance effect.

[0173] The method provided by the embodiment, also by receiving the control signal sent by the control device, the system chip sends the compensation signal to the timing controller, by the user using the control device, sending the control signal indicates the timing controller to execute electrical compensation, meet the user's demand for electrical compensation of the picture.

[0174] The method provided by the embodiment, also by the use time of the display panel is greater than the second time threshold, the system chip sends the compensation signal to the timing controller, so that the display panel can automatically execute electrical compensation after a long time of use, thereby protecting the display panel, prolonging the service life of the display panel.

[0175] The method provided by the embodiment, also by the use time of the display panel is greater than the third time threshold, the system chip controls the display panel to display the compensation control, in the case that the compensation control on the display panel is clicked, the system chip sends the compensation signal to the timing controller, so that the display panel can remind the user that the display panel needs to be electrically compensated after a long time of use, and whether to electrically compensate according to the user's selection, meet the different needs of the user to continue to watch or to electrically compensate.

[0176] Taking OLED TV as an example, when the user continuously watches the OLED TV for 5 hours, the user clicks the power button on the remote controller, and the remote controller sends a shutdown signal to the OLED TV.

[0177] Taking 4 hours as the first time threshold, as the use time of the display panel of the OLED television is greater than 4 hours and the system chip receives the power-off signal sent by the remote controller, the system chip sends a compensation signal to the timing controller.

[0178] In the case that the timing controller receives the compensation signal, the timing controller performs electrical compensation on the display panel. During the electrical compensation performed by the timing controller on the display panel, the system chip detects whether the remote controller sends an interrupt signal.

[0179] Suppose that after the user clicks the power key on the remote controller for a minute, he thinks that there is a program that has not been watched and decides to turn on the OLED television again by clicking the power key on the remote controller again to send an interrupt signal to the system chip, at this time the electrical compensation has not been completed.

[0180] After the system chip receives the interrupt signal, the interrupt signal is forwarded to the timing controller. After the timing controller receives the interrupt signal, the electrical compensation is interrupted. After the electrical compensation is interrupted, the timing controller uses the historical compensation voltage data to control the display panel to display the picture, so that the user can continue to watch the program that has not been watched, without waiting for the electrical compensation to be completed.

[0181] Taking the display device as an OLED television and 24 hours as the second time threshold, when the OLED television continuously displays a picture for 10 hours, as the use time of the display panel is less than 24 hours, the compensation control will not pop up on the display panel.

[0182] Suppose that the user decides to perform electrical compensation on the display panel to optimize the display effect of the OLED television, then the user selects the electrical compensation function in the client corresponding to the OLED television and selects to execute the function through the remote controller, and the remote controller sends a control signal to the system chip.

[0183] In the case that the system chip receives the control signal sent by the remote controller, the system chip sends a compensation signal to the timing controller. In the case that the timing controller receives the compensation signal, the timing controller performs electrical compensation on the display panel. During the electrical compensation performed by the timing controller on the display panel, the system chip detects whether the remote controller sends an interrupt signal.

[0184] Suppose that after the user selects to execute the electrical compensation function for a minute, he thinks that there is an urgent matter to be handled immediately, but he is worried that after the electrical compensation is completed, the OLED television is always in the display picture state, so he decides to interrupt the electrical compensation. The user sends an interrupt signal to the system chip by clicking the power key on the remote controller, at this time the electrical compensation has not been completed.

[0185] After receiving the interrupt signal, the system chip forwards the interrupt signal to the timing controller. After receiving the interrupt signal, the timing controller interrupts the electrical compensation. After interrupting the electrical compensation, the timing controller controls the display panel to shut down, so that the user can directly interrupt the electrical compensation and turn off the OLED television, avoiding the problem that the user cannot turn off the OLED television after the electrical compensation is completed and is not at home, resulting in waste of power, and there is no need to wait for the electrical compensation to be completed.

[0186] In the above embodiments, steps with the same serial numbers can be considered as the same step. The embodiment corresponding to FIG. 3, the embodiment corresponding to FIG. 4, the embodiment corresponding to FIG. 5, and the embodiment corresponding to FIG. 6 can be implemented separately or in combination, which is not limited in the present application.

[0187] FIG. 7 shows a flowchart of a compensation interrupt method provided by an example embodiment of the present application, which is performed by a display device including a system chip, a timing controller, and a display panel, and includes at least one of the following steps.

[0188] Step 701: The display device is powered on.

[0189] After the display device is connected to the power supply, the display device is powered on and enters a working state.

[0190] Step 702: The display panel displays a picture.

[0191] The display device further includes a video signal line for transmitting a video signal to the display panel.

[0192] In some embodiments, the display panel displays a picture according to the received video signal, for example, displays a video picture of a different channel.

[0193] Step 7031: The system chip determines whether a shutdown signal is received.

[0194] In some embodiments, the shutdown signal is sent by a control device, for example, sent by a remote controller.

[0195] In the case where the system chip determines that no shutdown signal is received, step 702 is performed, and the display panel continues to display a picture; in the case where the system chip determines that a shutdown signal is received, step 7041 is performed.

[0196] Step 7041: The timing controller determines whether the use duration of the display panel is greater than a first time threshold.

[0197] In some embodiments, in the case where the system chip receives a shutdown signal and the use duration of the display panel is greater than the first time threshold, the timing controller performs first electrical compensation on the display panel.

[0198] In some embodiments, the first electrical compensation is triggered by the system chip receiving a shutdown signal.

[0199] Optionally, the usage duration of the display panel is counted by the system chip or by the timing controller. In the embodiments of the present application, the usage duration of the display panel is counted by the timing controller as an example.

[0200] If the usage duration of the display panel is determined to be not greater than the first time threshold, step 7101 is performed; if the usage duration of the display panel is determined to be greater than the first time threshold, step 7051 is performed.

[0201] Step 7051: The timing controller starts the first electrical compensation.

[0202] In some embodiments, the timing controller starts the first electrical compensation on the display panel when the system chip receives a shutdown signal and the usage duration of the display panel is greater than the first time threshold.

[0203] Step 7061: The system chip detects an interrupt signal.

[0204] In some embodiments, the system chip detects an interrupt signal during the electrical compensation performed by the timing controller on the display panel, and the interrupt signal is used to indicate interrupting the electrical compensation.

[0205] Step 7071: The system chip determines whether the interrupt signal is received.

[0206] If the interrupt signal is determined to be received, step 708 is performed; if the interrupt signal is determined to be not received, step 7091 is performed.

[0207] Step 708: The system chip sends the interrupt signal to the timing controller.

[0208] In some embodiments, the system chip forwards the interrupt signal to the timing controller, which is used to instruct the timing controller to interrupt the electrical compensation.

[0209] In some embodiments, the system chip does not send a determined shutdown signal to the timing controller based on the first pre-configuration; and the timing controller uses the historical compensation voltage data to control the display panel to display a picture when the interrupt signal is received and the determined shutdown signal is not received.

[0210] The first pre-configuration is stored in the system chip, which is used to configure the system chip to, when the shutdown signal is received, after forwarding the interrupt signal, not send the determined shutdown signal to the timing controller, and the determined shutdown signal is used to instruct the timing controller to control the display panel to shut down.

[0211] The historical compensation voltage data is stored in the timing controller, and the timing controller uses the historical compensation voltage data to control the voltage of each pixel on the display panel.

[0212] In some embodiments, the system chip does not send the determination shutdown signal to the timing controller based on the second pre-configuration; and the timing controller uses the historical compensation voltage data to control the display panel to display the picture in the case that the interrupt signal is received and the determination shutdown signal is not received.

[0213] The second pre-configuration is stored in the system chip, and is used to configure the system chip to not send the determination shutdown signal to the timing controller after forwarding the interrupt signal in the case that the shutdown signal is not received, the determination shutdown signal being used to instruct the timing controller to control the display panel to shut down.

[0214] Step 7091: The timing controller completes the first electrical compensation.

[0215] In some embodiments, the timing controller sends an electrical compensation completion signal to the system chip after completing the first electrical compensation, the electrical compensation completion signal being used to instruct that the first electrical compensation is completed.

[0216] Step 7101: The display panel is shut down.

[0217] In some embodiments, the system chip sends the determination shutdown signal to the timing controller in the case that the shutdown signal is received by the system chip and the electrical compensation completion signal is received, the determination shutdown signal being used to instruct the timing controller to control the display panel to shut down.

[0218] In some embodiments, the system chip sends the determination shutdown signal to the timing controller in the case that the shutdown signal is received by the system chip and the usage time of the display panel is not greater than the first time threshold, the determination shutdown signal being used to instruct the timing controller to control the display panel to shut down.

[0219] Step 7032: The timing controller judges whether the compensation signal is received.

[0220] In some embodiments, the system chip sends the compensation signal to the timing controller, the compensation signal being used to instruct the timing controller to perform the electrical compensation.

[0221] In some embodiments, the system chip generates the compensation signal before sending the compensation signal to the timing controller, the compensation signal being used to instruct the timing controller to perform the electrical compensation, in the case that the compensation condition is met.

[0222] For example, the compensation condition comprises at least one of the following:

[0223] receiving the shutdown signal and the usage time of the display panel being greater than the first time threshold;

[0224] • receiving a control signal sent by the control device;

[0225] • the usage time of the display panel is greater than a second time threshold;

[0226] • the compensation control on the display panel is clicked.

[0227] In some embodiments, the second time threshold is greater than the first time threshold, for example, the second time threshold is 48 hours and the first time threshold is 4 hours.

[0228] For specific implementation details, refer to the embodiment of FIG. 6, which will not be repeated here.

[0229] In the case where the timing controller determines that the compensation signal is received, step 7042 is performed; in the case where it is determined that the compensation signal is not received, step 702, i.e., the normal display screen, is performed.

[0230] Step 7042: The timing controller starts the second electrical compensation.

[0231] In some embodiments, in the case where the timing controller receives the compensation signal, the timing controller starts to perform the second electrical compensation on the display panel.

[0232] In some embodiments, the second electrical compensation is an electrical compensation triggered by the timing controller receiving the compensation signal.

[0233] Step 7052: The system chip detects the interrupt signal.

[0234] For specific implementation details, refer to step 7061, which will not be repeated here.

[0235] Step 7062: The system chip determines whether the interrupt signal is received.

[0236] In the case where it is determined that the interrupt signal is received, step 708 is performed; in the case where it is determined that the interrupt signal is not received, step 7072 is performed.

[0237] Step 7072: The timing controller completes the second electrical compensation.

[0238] In some embodiments, after the timing controller completes the second electrical compensation, the timing controller sends an electrical compensation completion signal to the system chip, and the electrical compensation completion signal is used to indicate that the second electrical compensation is completed.

[0239] In some embodiments, after the timing controller completes the second electrical compensation, the timing controller does not perform electrical compensation on the display panel, and the display panel continues to display the screen according to the received video signal.

[0246] In summary, the method provided by the embodiment interrupts the electrical compensation after the display panel is powered off or the user actively performs the electrical compensation, and the display panel displays a picture using the historical compensation voltage data, thereby reducing the influence of the interruption of the electrical compensation on the picture and meeting the requirement of the user that the electrical compensation is not needed at present and the picture needs to be continuously watched.

[0247] FIG. 10 shows a flowchart of a compensation interruption method provided by an example embodiment of the present application, which is performed by a display device including a system chip, a timing controller and a display panel. Compared with the embodiment of FIG. 7, the method has different steps as shown below.

[0248] Step 1001: The system chip sends an interrupt signal to the timing controller.

[0249] In some embodiments, the system chip forwards the interrupt signal to the timing controller, for indicating that the timing controller interrupts the first electrical compensation.

[0250] In some embodiments, the system chip sends a determined power-off signal to the timing controller based on a third pre-configuration, and the timing controller controls the display panel to be powered off when the interrupt signal is received and the determined power-off signal is received.

[0251] The third pre-configuration is stored in the system chip, for configuring the system chip to send the determined power-off signal to the timing controller after the interrupt signal is forwarded when the power-off signal is received, and the determined power-off signal is used to indicate that the timing controller controls the display panel to be powered off.

[0252] Step 1002: The system chip sends an interrupt signal to the timing controller.

[0253] In some embodiments, the system chip forwards the interrupt signal to the timing controller, for indicating that the timing controller interrupts the second electrical compensation.

[0254] In some embodiments, the system chip does not send a determination shutdown signal to the timing controller based on the second pre-configuration; the timing controller controls the display panel to display a picture using the historical compensation voltage data in a case that the interrupt signal is received and the determination shutdown signal is not received.

[0255] The second pre-configuration is stored in the system chip, and is used to configure the system chip to not send a determination shutdown signal to the timing controller after forwarding the interrupt signal in a case that the determination shutdown signal is not received, the determination shutdown signal being used to instruct the timing controller to control the display panel to shut down.

[0256] The historical compensation voltage data is stored in the timing controller, and the timing controller uses the historical compensation voltage data to control the voltage of each pixel on the display panel.

[0257] In summary, the method provided by the embodiment can save the energy consumption of the display device by interrupting the electrical compensation after the shutdown and shutting down the display panel.

[0258] The method provided by the embodiment can also reduce the influence of the interruption of the electrical compensation on the picture by interrupting the electrical compensation after the user actively performs the electrical compensation and using the historical compensation voltage data to display the picture by the display panel, so as to meet the requirement of the user that the electrical compensation is not needed at present and the picture needs to be continuously watched.

[0259] FIG. 11 shows a flowchart of a compensation interruption method provided by an example embodiment of the application, the method being performed by a display device including a system chip, a timing controller and a display panel, and the method being different from the embodiment of FIG. 7 in the following steps.

[0260] Step 1101: The system chip sends an interrupt signal to the timing controller.

[0261] In some embodiments, the system chip forwards the interrupt signal to the timing controller, which is used to instruct the timing controller to interrupt the first electrical compensation.
