[0047] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0048] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0049] The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The singular forms “a,” “the,” and “the” used in this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0050] 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 used for analysis, data stored, data displayed, etc.) involved in this 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 must comply with the relevant laws, regulations and standards of the relevant countries and regions.

[0051] It should be understood that although the terms first, second, etc., may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, a first parameter may also be referred to as a second parameter, and similarly, a second parameter may also be referred to as a first parameter. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0052] First, let me explain some of the terms used in this application:

[0053] Electrical compensation: This is a method to improve image quality by extracting electrical characteristic data from a power system, calculating and adjusting the electrical characteristic data. In this application embodiment, voltage adjustment is usually taken as an example for electrical compensation.

[0054] In the pixel circuitry of an Organic Light Emitting Diode (OLED), at least two thin-film transistors (TFTs) are required for driving. TFTs are typically selected from Low-Temperature Poly-Silicon (LTPS) TFTs or Metal Oxide (MO) TFTs. LTPS TFTs are generally suitable for small-sized OLED displays because of their higher mobility and smaller device footprint, making them more suitable for high pixel density applications. MOF TFTs, due to their superior uniformity, are generally used in large-sized OLED displays.

[0055] However, both have drawbacks. When producing LTPS TFTs on large-area glass substrates, TFTs at different locations may exhibit differences in certain electrical parameters, such as threshold voltage and mobility, leading to uneven brightness. Metal oxide TFTs, under prolonged pressure and temperature increases, also experience threshold voltage drift, resulting in image retention issues.

[0056] Figure 1 A schematic diagram of a display device 100 provided in an exemplary embodiment of this application is shown. The display device 100 includes: a system chip 101, a timing controller 102, and a display panel 103.

[0057] The display panel 103 in this embodiment includes various display panels, which can be selected and set 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 (MicroLED) display panel, etc. This embodiment does not limit the specific type of display panel, but usually takes an OLED display panel as an example for illustration.

[0058] For display panel 103, to ensure its display effect, electrical compensation technology is used to solve the above problems. Electrical compensation is achieved by transmitting the current-voltage characteristics of the TFT and the OLED to the sensing circuit through the TFT inside the pixel. Figure 1 (Not shown in the diagram) The system calculates the voltage value to be compensated and feeds it back to the system chip 101 to achieve electrical compensation. This part of the work can be completed by the timing controller (TCON) 102. The timing controller 102 provides the calculated compensation voltage to each pixel row by row or column by column for compensation. Therefore, the system chip (SoC) 101 does not need to provide display signals during the compensation process. However, the SoC 101 and the power supply are still working normally to ensure that the overall system is in the powered-on state during the compensation process, and that the communication between the SoC 101 and the timing controller 102 is also normal. For example, after the electrical compensation is completed, the timing controller 102 sends a stop signal to the SoC 101.

[0059] During the electrical compensation process in related technologies, the timing controller 102 controls the display panel 103 to display a completely black screen, compensating for each pixel. Taking an OLED display panel as an example, the electrical compensation process lasts approximately 10 minutes. After the electrical compensation is completed, the system chip 101 receives a termination signal and performs a power-off operation. If the electrical compensation is unsuccessful and is not completed within 10 minutes, the system chip 101 will perform a power-off operation based on a preset upper limit for the compensation time, such as 25 minutes.

[0060] Electrical compensation requires a relatively long execution time. Furthermore, if the user issues other commands to the OLED display panel during the electrical compensation process, the OLED display panel can only respond to the other commands after the electrical compensation is completed.

[0061] To address the aforementioned problems, this application provides a display device 100. Figure 2The illustration shows a schematic diagram of a display device 100 and a control device 110 provided in an exemplary embodiment of this application. The display device 100 includes a system chip 101, a timing controller 102, and a display panel 103.

[0062] In some embodiments, the system chip 101 is configured to detect an interrupt signal during the electrical compensation performed on the display panel 103 by the timing controller 102, the interrupt signal indicating the interruption of 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; the timing controller 102 is configured to interrupt the electrical compensation according to the interrupt signal.

[0063] When the display device 100 is in a sense compensation state, the system chip 101 detects an interrupt signal. While the display device 100 is in the sense compensation state, the system chip 101 detects an interrupt signal simultaneously with the timing controller 102 performing electrical compensation. In this embodiment, the terms "sensing," "detection," "induction," and "checking" have the same meaning. Typically, "detection" is used as an example for explanation; that is, when the display device 100 is in the sense compensation state, it can be understood as the timing controller 102 in the display device 100 performing electrical compensation while the system chip 101 detects an interrupt signal.

[0064] Optionally, the interrupt signal is sent by the control device 110, for example, when the user clicks the power button on the remote control, the remote control sends an interrupt signal.

[0065] System chip 101 is used to send interrupt signals to timing controller 102:

[0066] In some embodiments, the system chip 101 is used to send an interrupt signal to the timing controller 102 in response to receiving an interrupt signal sent by the control device 110; wherein the control device 110 is used to control the display device 100.

[0067] For example, the control device 110 includes at least one of the following: a remote control, a smartphone, a touch screen control device, a gesture control device, and a physical button control device. This application typically uses a remote control as an example for illustration, and does not limit the control device 110.

[0068] When the control device 110 is a remote control, the remote control sends an interrupt signal in response to a control button on the remote control being clicked. For example, the control button includes at least one of the following: power button, confirmation button, back button, and home button. The control button can also be any other button on the remote control, and this application embodiment does not limit this.

[0069] Optionally, the system chip 101 is used to generate a prompt signal in response to receiving an interrupt signal sent by the control device 110, and send the prompt signal to the display panel 103; the display panel 103 is used to display a prompt control according to the prompt signal, the prompt control being used for the user to confirm whether to interrupt electrical compensation; if the interruption of electrical compensation is confirmed, the system chip 101 is used to receive a confirmation signal sent by the control device 110; the system chip 101 is used to send an interrupt signal to the timing controller 102 in response to receiving the confirmation signal.

[0070] After receiving an interrupt signal, the system chip 101 does not immediately send an interrupt signal to the timing controller 102. Instead, it generates a prompt signal and sends it to the display panel 103. Upon receiving the prompt signal, the display panel 103 displays prompt controls, such as a prompt window, including "Interrupt electrical compensation?", a confirmation button, and a cancel button.

[0071] When the user clicks the confirmation button via control device 110, control device 110 sends a confirmation signal to system chip 101. Upon receiving the confirmation signal, system chip 101 sends an interrupt signal to timing controller 102.

[0072] When the user clicks the cancel button via control device 110, control device 110 sends a cancel signal to system chip 101. System chip 101 does not send an interrupt signal to timing controller 102 if it receives the cancel signal or does not receive an acknowledgment signal.

[0073] After the electrical compensation is interrupted, the display panel 103 will show a screen or the device will be turned off.

[0074] In some embodiments, the timing controller 102 is used to control the display panel to display a screen after the electrical compensation is interrupted, using historical compensation voltage data; wherein, the historical compensation voltage data is the compensation voltage data before the current electrical compensation.

[0075] Optionally, historical compensation voltage data is stored in the timing controller 102.

[0076] In the case of multiple electrical compensations, the timing controller 102 stores historical compensation voltage data, which includes the voltage value that each pixel needs to be compensated for in a previous electrical compensation.

[0077] By way of example and not limitation, historical compensation voltage data includes at least one of the following: compensation voltage data from the previous electrical compensation; or preset compensation voltage data.

[0078] 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.

[0079] In some embodiments, the timing controller 102 is used to control the display panel to shut down after an electrical compensation interruption.

[0080] To save energy, the control display panel will shut down and will not re-display the image after the electrical compensation is interrupted.

[0081] Electrical compensation process:

[0082] In some embodiments, the system chip 101 is used to send a compensation signal to the timing controller 102; the timing controller 102 is used 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.

[0083] In some embodiments, the system chip 101 is used to generate a compensation signal and send the compensation signal to the timing controller 102 when the compensation conditions are met.

[0084] For example, the compensation conditions include at least one of the following:

[0085] • A power-off signal is received, and the usage time of the display panel 103 exceeds the first time threshold;

[0086] • Received a control signal sent by control device 110;

[0087] • The usage time of display panel 103 exceeds the second time threshold;

[0088] • The compensation control on display panel 103 was clicked.

[0089] 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.

[0090] The compensation conditions can be preset, and this application does not limit this. As long as the compensation conditions are met, the system chip 101 can generate a compensation signal. For example, the display panel 103 includes a compensation control to enable the compensation function. When the user selects to enable the compensation function by clicking the compensation control, the timing controller 102 performs electrical compensation. Another example is setting the electrical compensation to be performed automatically each time the device is powered off.

[0091] (1) In some embodiments, the system chip 101 is used to send a compensation signal to the timing controller 102 when a power-off signal is received and the usage time of the display panel 103 is greater than a first time threshold; wherein the power-off signal is used to instruct the display panel 103 to power off.

[0092] Normally, the first time threshold is a relatively 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 power-off signal, the system chip 101 will not send a compensation signal to the timing controller 102.

[0093] For example, if 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 a power-off signal, the system chip 101 will not send a compensation signal to the timing controller 102, because the usage time is short at this time and the display effect of the display panel 103 is not affected, so there is no need to perform electrical compensation.

[0094] (2) In some embodiments, the system chip 101 is used to send a compensation signal to the timing controller 102 when it receives a control signal sent by the control device 110; wherein the control signal is used to instruct the timing controller 102 to perform electrical compensation on the display panel 103.

[0095] For example, when the compensation button on the control device 110 is clicked, the control device 110 sends a control signal; or, when "Perform electrical compensation?" is displayed on the display panel 103, the user clicks the confirmation button on the control device, and the control device 110 sends a control signal.

[0096] (3) In some embodiments, the system chip 101 is used to send a compensation signal to the timing controller 102 when the usage time of the display panel 103 exceeds a second time threshold.

[0097] Typically, the second time threshold is a relatively large threshold. For example, the second time threshold is 48 hours, meaning that if the usage time of the display panel 103 exceeds 48 hours, the system chip 101 sends a compensation signal to the timing controller 102, and the timing controller 102 performs electrical compensation. This protects the display panel and extends its lifespan.

[0098] (4) In some embodiments, the system chip 101 is used to send a compensation signal to the timing controller 102 when the compensation control on the display panel 103 is clicked.

[0099] For example, control device 110 sends an indication signal to indicate whether the compensation control is clicked. When control device 110 sends a corresponding indication signal, the compensation control is clicked, and system chip 101 sends a compensation signal to timing controller 102.

[0100] For example, if the display panel 103 is a touch screen, when the compensation control on the display panel 103 is clicked, the system chip 101 sends a compensation signal to the timing controller 102.

[0101] Optionally, the system chip 101 is used to control the display panel 103 to display compensation controls when the usage duration of the display panel 103 is greater than or equal to a third time threshold.

[0102] Typically, the third time threshold is a relatively large threshold. For example, the third time threshold is 24 hours. When the usage time of the display panel 103 is equal to 24 hours, the system chip 101 controls the display panel 103 to display compensation controls. The compensation controls include "whether to perform electrical compensation", as well as confirmation and cancellation controls.

[0103] If, after the display panel 103 displays the compensation control for the first time, the user selects not to perform electrical compensation, then the system chip 101 can control the display panel 103 to stop displaying the compensation control, or periodically control the display panel 103 to display the compensation control. For example, if the display panel 103 is used for more than 24 hours, the system chip 101 controls the display panel 103 to display the compensation control once every 2 hours.

[0104] In summary, the device provided in this embodiment can interrupt electrical compensation during the electrical compensation process by having the system chip detect an interrupt signal. When the system chip receives the interrupt signal, it forwards the interrupt signal to the timing controller, which then interrupts the electrical compensation. This avoids the problem that the display panel cannot respond to other commands until the electrical compensation is completed, thus improving the flexibility of electrical compensation.

[0105] The device provided in this embodiment also reduces the impact of electrical compensation interruption on the screen by displaying the screen based on historical compensation voltage data after electrical compensation is interrupted, thereby meeting the user's need to continue watching the screen even if electrical compensation is not currently needed; or by turning off the display panel after electrical compensation is interrupted, the energy consumption of the display device is saved.

[0106] Figure 3 A flowchart of a compensation interruption method provided in an exemplary embodiment of this application is shown. The method is performed by a display device 100, which includes a system chip 101, a timing controller 102, and a display panel 103. The method includes at least one of the following steps.

[0107] Step 310: The timing controller 102 performs electrical compensation on the display panel 103.

[0108] In some embodiments, electrical compensation is performed to ensure the display effect of the display panel 103.

[0109] Electrical compensation is achieved by transmitting the current-voltage characteristics of the TFT inside the pixel to the sensing circuit. Figure 1 (Not shown in the image) The system calculates the voltage value to be compensated and feeds it back to the system chip 101 to achieve electrical compensation. This part of the work can be completed by the timing controller 102. The timing controller 102 provides the calculated compensation voltage to each pixel row by row or column by column for compensation. Therefore, the system chip 101 does not need to provide a display signal 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 the powered-on state during the compensation process, and that 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 a stop signal to the system chip 101.

[0110] During the electrical compensation process, the timing controller 102 controls the display panel 103 to display a completely black screen, compensating for each pixel. Taking an OLED display panel as an example, the electrical compensation process lasts approximately 10 minutes. After the electrical compensation is completed, the system chip 101 receives a termination signal and performs a power-off operation. If the electrical compensation is unsuccessful and is not completed within 10 minutes, the system chip 101 will perform a power-off operation based on a preset upper limit for the compensation time, such as 25 minutes.

[0111] Step 320: System chip 101 detects the interrupt signal.

[0112] During the electrical compensation performed on the display panel 103 by the timing controller 102, the system chip 101 detects an interrupt signal, which is used to indicate the interruption of electrical compensation.

[0113] Step 330: System chip 101 sends an interrupt signal to timing controller 102.

[0114] In response to receiving an interrupt signal, the system chip 101 sends the interrupt signal to the timing controller 102.

[0115] The interrupt signal is used to indicate interrupt 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.

[0116] Step 340: Interrupt electrical compensation for timing controller 102.

[0117] The timing controller 102 is used to control the execution or interruption of electrical compensation. Upon receiving an interrupt signal, the timing controller 102 interrupts the electrical compensation according to the interrupt signal.

[0118] In summary, the method provided in this embodiment detects an interrupt signal during the electrical compensation process performed by the timing controller. When the system chip receives the interrupt signal, it forwards the interrupt signal to the timing controller, which then interrupts the electrical compensation. This allows the electrical compensation process to be interrupted, avoiding the problem that the display panel cannot respond to other commands until the electrical compensation is completed, thus improving the flexibility of the electrical compensation.

[0119] Figure 4 A flowchart of a compensation interruption method provided in an exemplary embodiment of this application is shown. The method is performed by a display device 100 and a control device 110. The display device 100 includes a system chip 101, a timing controller 102, and a display panel 103. The method includes at least one of the following steps.

[0120] Step 310: The timing controller 102 performs electrical compensation on the display panel 103.

[0121] Step 320: System chip 101 detects the interrupt signal.

[0122] Step 329: Control device 110 sends an interrupt signal to system chip 101.

[0123] For example, the control device 110 includes at least one of the following: a remote control, a smartphone, a touch screen control device, a gesture control device, and a physical button control device. This application typically uses a remote control as an example for illustration, and does not limit the control device 110.

[0124] When the control device 110 is a remote control, the remote control sends an interrupt signal in response to a control button on the remote control being clicked. For example, the control button includes at least one of the following: power button, confirmation button, back button, and home button.

[0125] Step 330: System chip 101 sends an interrupt signal to timing controller 102.

[0126] In some embodiments, in response to receiving an interrupt signal sent by the control device 110, the system chip 101 sends an interrupt signal to the timing controller 102; wherein, the control device 110 is used to control the display device 100.

[0127] Optionally, in response to receiving an interrupt signal from the control device 110, the system chip 101 generates a prompt signal 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 the user to confirm whether to interrupt electrical compensation; if the interruption of electrical compensation is confirmed, the system chip 101 receives a confirmation signal from the control device 110; in response to receiving the confirmation signal, the system chip 101 sends an interrupt signal to the timing controller 102.

[0128] After receiving an interrupt signal, the system chip 101 does not immediately send an interrupt signal to the timing controller 102. Instead, it generates a prompt signal and sends it to the display panel 103. Upon receiving the prompt signal, the display panel 103 displays prompt controls, such as a prompt window, including "Interrupt electrical compensation?", a confirmation button, and a cancel button.

[0129] When the user clicks the confirmation button via control device 110, control device 110 sends a confirmation signal to system chip 101. Upon receiving the confirmation signal, system chip 101 sends an interrupt signal to timing controller 102.

[0130] When the user clicks the cancel button via control device 110, control device 110 sends a cancel signal to system chip 101. System chip 101, upon receiving the cancel signal or without receiving an acknowledgment signal, does not send an interrupt signal to timing controller 102.

[0131] Step 340: Interrupt electrical compensation for timing controller 102.

[0132] In summary, the method provided in this embodiment, in response to receiving an interrupt signal sent by the control device, the system chip sends the interrupt signal to the timing controller, and the control device, such as a remote control, controls the display device. This method is simple and convenient, allowing users to interrupt electrical compensation at any time during the electrical compensation process without requiring cumbersome operation procedures.

[0133] Figure 5 This application illustrates a flowchart of an exemplary embodiment of a method for compensating for interruptions, executed by a display device 100, which includes a system chip 101, a timing controller 102, and a display panel 103. Figure 3 Compared to the previous embodiment, this method further includes the following steps.

[0134] Step 350: The timing controller 102 controls the display panel 103 to display the screen or shut down the device.

[0135] In some embodiments, after electrical compensation is interrupted, the timing controller 102 uses historical compensation voltage data to control the display panel 103 to display a screen; wherein, the historical compensation voltage data is the compensation voltage data before the current electrical compensation.

[0136] Optionally, historical compensation voltage data is stored in the timing controller 102.

[0137] In the case of multiple electrical compensations, the timing controller 102 stores historical compensation voltage data, which includes the voltage value that each pixel needs to be compensated for in a previous electrical compensation.

[0138] By way of example and not limitation, historical compensation voltage data includes at least one of the following: compensation voltage data from the previous electrical compensation; or preset compensation voltage data.

[0139] When this 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 this electrical compensation is the first electrical compensation, the preset compensation voltage data is used as the historical compensation voltage data.

[0140] In some embodiments, after electrical compensation is interrupted, the timing controller 102 controls the display panel 103 to shut down.

[0141] To save energy, the display panel 103 will not restart after the electrical compensation is interrupted and will shut down.

[0142] In summary, the method provided in this embodiment reduces the impact of electrical compensation interruption on the screen by displaying the screen based on historical compensation voltage data after electrical compensation is interrupted, thereby meeting the user's need to continue watching the screen even if electrical compensation is not currently needed; or it saves energy consumption of the display device by turning off the display panel after electrical compensation is interrupted.

[0143] Figure 6 A flowchart of a compensation interruption method provided in an exemplary embodiment of this application is shown. The method is performed by a display device 100, which includes a system chip 101, a timing controller 102, and a display panel 103. The method includes at least one of the following steps.

[0144] Step 301: System chip 101 sends a compensation signal to timing controller 102.

[0145] In some embodiments, before the system chip 101 sends a compensation signal to the timing controller 102, the system chip 101 generates a compensation signal if the compensation conditions are met. The compensation signal is used to instruct the timing controller 102 to perform electrical compensation.

[0146] For example, the compensation conditions include at least one of the following:

[0147] • A power-off signal is received, and the usage time of the display panel 103 exceeds the first time threshold;

[0148] • Received a control signal sent by control device 110;

[0149] • The usage time of display panel 103 exceeds the second time threshold;

[0150] • The compensation control on display panel 103 was clicked.

[0151] 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.

[0152] The compensation conditions can be preset, and this application does not limit this. As long as the compensation conditions are met, the system chip 101 can generate a compensation signal. For example, the display panel 103 includes a compensation control to enable the compensation function. When the user selects to enable the compensation function by clicking the compensation control, the timing controller 102 performs electrical compensation. Another example is setting the electrical compensation to be performed automatically each time the device is powered off.

[0153] (1) In some embodiments, when a power-off signal is received and the usage time of the display panel 103 exceeds a first time threshold, the system chip 101 sends a compensation signal to the timing controller 102; wherein the power-off signal is used to instruct the display panel 103 to power off.

[0154] Normally, the first time threshold is a relatively 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 power-off signal, the system chip 101 will not send a compensation signal to the timing controller 102.

[0155] For example, if 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 a power-off signal, the system chip 101 will not send a compensation signal to the timing controller 102, because the usage time is short at this time and the display effect of the display panel 103 is not affected, so there is no need to perform electrical compensation.

[0156] (2) In some embodiments, when a control signal is received from a 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.

[0157] For example, when the compensation button on the control device 110 is clicked, the control device 110 sends a control signal; or, when "Perform electrical compensation?" is displayed on the display panel 103, the user clicks the confirmation button on the control device, and the control device 110 sends a control signal.

[0158] (3) In some embodiments, when the usage time of the display panel 103 exceeds the second time threshold, the system chip 101 sends a compensation signal to the timing controller 102.

[0159] Typically, the second time threshold is a relatively large threshold. For example, the second time threshold is 48 hours, meaning that if the usage time of the display panel 103 exceeds 48 hours, the system chip 101 sends a compensation signal to the timing controller 102, and the timing controller 102 performs electrical compensation. This protects the display panel and extends its lifespan.

[0160] (4) In some embodiments, when the compensation control on the display panel 103 is clicked, the system chip 101 sends a compensation signal to the timing controller 102.

[0161] For example, control device 110 sends an indication signal to indicate whether the compensation control is clicked. When control device 110 sends a corresponding indication signal, the compensation control is clicked, and system chip 101 sends a compensation signal to timing controller 102.

[0162] For example, if the display panel 103 is a touch screen, when the compensation control on the display panel 103 is clicked, the system chip 101 sends a compensation signal to the timing controller 102.

[0163] Optionally, if the usage time of the display panel 103 exceeds a third time threshold, the system chip 101 controls the display panel 103 to display compensation controls.

[0164] Typically, the third time threshold is a relatively large threshold. For example, the third time threshold is 24 hours. When the usage time of the display panel 103 is equal to 24 hours, the system chip 101 controls the display panel 103 to display compensation controls. The compensation controls include "whether to perform electrical compensation", as well as confirmation and cancellation controls.

[0165] If, after the display panel 103 displays the compensation control for the first time, the user selects not to perform electrical compensation, then the system chip 101 can control the display panel 103 to stop displaying the compensation control, or periodically control the display panel 103 to display the compensation control. For example, if the display panel 103 is used for more than 24 hours, the system chip 101 controls the display panel 103 to display the compensation control once every 2 hours.

[0166] Step 310: The timing controller 102 performs electrical compensation on the display panel 103.

[0167] In some embodiments, when the timing controller 102 receives a compensation signal, the timing controller 102 performs electrical compensation on the display panel 103.

[0168] Step 320: System chip 101 detects the interrupt signal.

[0169] Step 330: System chip 101 sends an interrupt signal to timing controller 102.

[0170] Step 340: Interrupt electrical compensation for timing controller 102.

[0171] In summary, the method provided in this embodiment improves the picture performance by sending a compensation signal to the timing controller when a power-off signal is received and the usage time of the display panel exceeds a first time threshold. This causes the display panel to undergo electrical compensation after a certain period of use.

[0172] The method provided in this embodiment also involves the system chip sending a compensation signal to the timing controller upon receiving a control signal from the control device. The user then uses the control device to send a control signal to instruct the timing controller to perform electrical compensation, thereby meeting the user's need for electrical compensation for the screen.

[0173] The method provided in this embodiment also allows the system chip to send a compensation signal to the timing controller when the usage time of the display panel exceeds a second time threshold. This enables the display panel to automatically perform electrical compensation after a long period of use, thereby protecting the display panel and extending its service life.

[0174] The method provided in this embodiment also includes a system chip controlling the display panel to display compensation controls when the usage time of the display panel exceeds a third time threshold. When the compensation controls on the display panel are clicked, the system chip sends a compensation signal to the timing controller. This allows the display panel to remind the user that it needs electrical compensation after a long period of use, and to decide whether to perform electrical compensation based on the user's choice, thus meeting the user's different needs of continuing to watch or performing electrical compensation.

[0175] Taking an OLED TV as an example, after a user watches an OLED TV continuously for 5 hours, the user clicks the power button on the remote control, and the remote control sends a power-off signal to the OLED TV.

[0176] Taking a first time threshold of 4 hours as an example, since the OLED TV's display panel is used for more than 4 hours and the system chip receives the power-off signal sent by the remote control, the system chip sends a compensation signal to the timing controller.

[0177] Upon receiving a compensation signal, the timing controller performs electrical compensation on the display panel. During this electrical compensation process, the system chip detects whether the remote control has sent an interrupt signal.

[0178] Suppose that a user presses the power button on the remote control and waits one minute before realizing that a program is not yet finished, and decides to turn on the OLED TV again. By pressing the power button on the remote control again, an interrupt signal is sent to the system chip. At this time, the electrical compensation has not yet been completed.

[0179] After receiving an interrupt signal, the system chip forwards it to the timing controller. Upon receiving the interrupt signal, the timing controller interrupts the electrical compensation process. After the electrical compensation is interrupted, the timing controller uses historical compensation voltage data to control the display panel, allowing the user to continue watching unfinished programs without waiting for the electrical compensation to complete.

[0180] Taking an OLED TV as an example, with a second time threshold of 24 hours, after the OLED TV has been displaying images continuously for 10 hours, the compensation control will not pop up on the display panel because the usage time of the display panel is less than 24 hours.

[0181] Suppose a user decides to perform electrical compensation on the display panel to optimize the display effect of the OLED TV. The user selects the electrical compensation function in the corresponding client of the OLED TV and selects to execute the function through the remote control. The remote control sends a control signal to the system chip.

[0182] Upon receiving a control signal from the remote control, the system chip sends a compensation signal to the timing controller. Upon receiving the compensation signal, the timing controller performs electrical compensation on the display panel. During this electrical compensation process, the system chip checks whether the remote control has sent an interrupt signal.

[0183] Suppose a user selects the electrical compensation function and waits one minute, then realizes they have an urgent matter to attend to and needs to leave immediately. However, they worry that the OLED TV will remain displaying an image after the compensation is complete, so they decide to interrupt the compensation process. The user sends an interrupt signal to the system chip by pressing the power button on the remote control; at this point, the electrical compensation is not yet complete.

[0184] After receiving an interrupt signal, the system chip forwards it to the timing controller. Upon receiving the interrupt signal, the timing controller interrupts electrical compensation. Following the interruption of electrical compensation, the timing controller shuts down the display panel, allowing the user to directly interrupt electrical compensation and turn off the OLED TV. This avoids the problem of wasted electricity caused by the user being away from home after electrical compensation is completed and unable to turn off the OLED TV, eliminating the need to wait for the compensation to finish.

[0185] In the above embodiments, steps with the same sequence number can be considered as the same step. Wherein, Figure 3 Corresponding embodiments, Figure 4 Corresponding embodiments, Figure 5 Corresponding embodiments and Figure 6 The corresponding embodiments can be implemented individually or in combination, and this application does not limit them.

[0186] Figure 7 A flowchart of a compensation interruption method provided in an exemplary embodiment of this application is shown. The method is performed by a display device, which includes a system chip, a timing controller, and a display panel. The method includes at least one of the following steps.

[0187] Step 701: Power on the display device.

[0188] After the display device is connected to the power supply, it powers on and enters the working state.

[0189] Step 702: Display panel shows screen.

[0190] The display device also includes a video signal cable, which is used to transmit video signals to the display panel.

[0191] In some embodiments, the display panel displays images based on the received video signal, such as displaying video images from different channels.

[0192] Step 7031: The system chip determines whether a power-off signal has been received.

[0193] In some embodiments, the power-off signal is sent by a control device, such as a remote control.

[0194] If the system chip determines that no power-off signal has been received, step 702 is executed, and the display panel continues to display the screen; if the system chip determines that a power-off signal has been received, step 7041 is executed.

[0195] Step 7041: The timing controller determines whether the usage time of the display panel is greater than the first time threshold.

[0196] In some embodiments, when the system chip receives a power-off signal and the usage time of the display panel exceeds a first time threshold, the timing controller performs a first electrical compensation on the display panel.

[0197] In some embodiments, the first electrical compensation is triggered by the system chip receiving a shutdown signal.

[0198] Optionally, the usage time of the display panel can be timed via a system chip or a timing controller. This embodiment uses the timing controller to measure the usage time of the display panel as an example.

[0199] If the usage time of the display panel is determined to be no greater than the first time threshold, proceed to step 7101; if the usage time of the display panel is determined to be greater than the first time threshold, proceed to step 7051.

[0200] Step 7051: The timing controller begins the first electrical compensation.

[0201] In some embodiments, when the system chip receives a power-off signal and the usage time of the display panel exceeds a first time threshold, the timing controller begins to perform first electrical compensation on the display panel.

[0202] Step 7061: The system chip detects the interrupt signal.

[0203] In some embodiments, the system chip detects an interrupt signal during the timing controller's electrical compensation of the display panel, the interrupt signal indicating an interruption of the electrical compensation.

[0204] Step 7071: The system chip determines whether an interrupt signal has been received.

[0205] If an interrupt signal is received, proceed to step 708; if no interrupt signal is received, proceed to step 7091.

[0206] Step 708: The system chip sends an interrupt signal to the timing controller.

[0207] In some embodiments, the system chip forwards an interrupt signal to the timing controller to instruct the timing controller to interrupt electrical compensation.

[0208] In some embodiments, the system chip, based on a first pre-configuration, does not send a definitive shutdown signal to the timing controller; when the timing controller receives an interrupt signal but does not receive a definitive shutdown signal, it uses historical compensated voltage data to control the display panel to display the screen.

[0209] The first pre-configuration is stored in the system chip and is used to configure the system chip not to send a confirmed shutdown signal to the timing controller after forwarding the interrupt signal when it receives a shutdown signal. The confirmed shutdown signal is used to instruct the timing controller to control the display panel to shut down.

[0210] Historical compensation voltage data is stored in the timing controller, which uses this data to control the voltage of each pixel on the display panel.

[0211] In some embodiments, the system chip, based on a second pre-configuration, does not send a definitive shutdown signal to the timing controller; if the timing controller receives an interrupt signal but does not receive a definitive shutdown signal, it uses historical compensation voltage data to control the display panel to display the screen.

[0212] The second pre-configuration is stored in the system chip and is used to configure the system chip not to send a confirmed shutdown signal to the timing controller after forwarding the interrupt signal if it does not receive a shutdown signal. The confirmed shutdown signal is used to instruct the timing controller to control the display panel to shut down.

[0213] Step 7091: The timing controller completes the first electrical compensation.

[0214] In some embodiments, after the timing controller completes the first electrical compensation, it sends an electrical compensation completion signal to the system chip. The electrical compensation completion signal is used to indicate that the first electrical compensation is complete.

[0215] Step 7101: Power off the display panel.

[0216] In some embodiments, when the system chip receives a power-off signal and an electrical compensation completion signal, the system chip sends a confirmation power-off signal to the timing controller, which is used to instruct the timing controller to power off the display panel.

[0217] In some embodiments, when the system chip receives a power-off signal and the usage time of the display panel is not greater than a first time threshold, the system chip sends a power-off confirmation signal to the timing controller. The power-off confirmation signal is used to instruct the timing controller to power off the display panel.

[0218] Step 7032: The timing controller determines whether a compensation signal has been received.

[0219] In some embodiments, the system chip sends a compensation signal to the timing controller, which instructs the timing controller to perform electrical compensation.

[0220] In some embodiments, before the system chip sends a compensation signal to the timing controller, the system chip generates a compensation signal if the compensation conditions are met. The compensation signal is used to instruct the timing controller to perform electrical compensation.

[0221] For example, the compensation conditions include at least one of the following:

[0222] • A power-off signal is received, and the duration of use of the display panel exceeds the first time threshold;

[0223] • Received control signals sent by the control equipment;

[0224] • The duration of display panel usage exceeds the second time threshold;

[0225] • The compensation control on the display panel was clicked.

[0226] 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.

[0227] For detailed implementation information, please refer to... Figure 6 Examples are not described here.

[0228] If the timing controller determines that a compensation signal has been received, step 7042 is executed; if it determines that no compensation signal has been received, step 702 is executed, i.e., the screen is displayed normally.

[0229] Step 7042: The timing controller begins the second electrical compensation.

[0230] In some embodiments, when the timing controller receives a compensation signal, the timing controller begins to perform a second electrical compensation on the display panel.

[0231] In some embodiments, the second electrical compensation is triggered by the timing controller receiving a compensation signal.

[0232] Step 7052: The system chip detects the interrupt signal.

[0233] For specific implementation details, please refer to step 7061, which will not be repeated here.

[0234] Step 7062: The system chip determines whether an interrupt signal has been received.

[0235] If an interrupt signal is received, proceed to step 708; if no interrupt signal is received, proceed to step 7072.

[0236] Step 7072: The timing controller completes the second electrical compensation.

[0237] In some embodiments, after the timing controller completes the second electrical compensation, it sends an electrical compensation completion signal to the system chip. The electrical compensation completion signal is used to indicate that the second electrical compensation is complete.

[0238] 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 image according to the received video signal.

[0239] Figure 8 A timing diagram illustrating the completion of electrical compensation provided in an exemplary embodiment of this application is shown.

[0240] Among them, rcec is the compensation signal, sense_flag is the flag signal for compensation action, ecd is the electrical compensation completion signal, eci is the electrical compensation interruption signal, mode_reset is the mode reset signal, and black is the black screen state signal. The compensation signal is used to instruct the timing controller to start electrical compensation. It is sent to the timing controller by the system chip. A high level indicates that it is sending, and a low level indicates that it is not sending. The compensation action flag signal is used to indicate whether the timing controller is performing electrical compensation. It is an internal signal of the timing controller. A high level indicates that electrical compensation is being performed, and a low level indicates that electrical compensation is not being performed. The electrical compensation completion signal is used to indicate that electrical compensation is completed. It is sent to the system chip by the timing controller. A high level indicates that electrical compensation is completed, and a low level indicates that electrical compensation is not completed. The electrical compensation interruption signal is used to indicate that electrical compensation is interrupted. It is sent to the timing controller by the system chip. A high level indicates that electrical compensation is interrupted, and a low level indicates that electrical compensation is not interrupted. The mode reset signal is used to indicate a change in the display device mode. It is an internal signal of the timing controller. A high level indicates a change in mode, and a low level indicates no change in mode. For example, switching from normal display mode to electrical compensation mode, or switching from electrical compensation mode to normal display mode. The black screen status signal is used to indicate whether the display panel is in a black screen state. It is sent to the display panel by the timing controller. A high level indicates that the display panel is in a black screen state, and a low level indicates that the display panel is not in a black screen state.

[0241] like Figure 8 As shown, during the period t0-t1, the compensation signal is at a high level, indicating that the timing controller will start performing electrical compensation after t1; during the period t1-t2, the mode reset signal is at a high level, indicating the switch from normal display mode to electrical compensation mode; during the period t1-t3, the compensation action flag signal is at a high level, indicating that the timing controller is performing electrical compensation during this period; at time t3, the electrical compensation completion signal goes high, indicating that electrical compensation is complete; during the period t1-t3, the black screen status signal is at a high level, indicating that the display panel is in a black screen state; during the period t3-t4, the mode reset signal is at a high level, indicating the switch from electrical compensation mode to normal display mode.

[0242] Figure 9A timing diagram of interruption electrical compensation provided in an exemplary embodiment of this application is shown.

[0243] Among them, rcec is the compensation signal, sense_flag is the flag signal for compensation action, ecd is the electrical compensation completion signal, eci is the electrical compensation interruption signal, mode_reset is the mode reset signal, and black is the black screen state signal.

[0244] like Figure 9 As shown, during the period t0-t1, the compensation signal is at a high level, indicating that the timing controller will start performing electrical compensation after t1; during the period t1-t2, the mode reset signal is at a high level, indicating a switch from normal display mode to electrical compensation mode; during the period t1-t3, the compensation action flag signal is at a high level, indicating that the timing controller is performing electrical compensation during this period; during the period t3-t4, the electrical compensation interruption signal is at a high level, indicating that electrical compensation is interrupted; during the period t1-t3, the black screen status signal is at a high level, indicating that the display panel is in a black screen state; during the period t4-t5, the mode reset signal is at a high level, indicating a switch from electrical compensation mode to normal display mode.

[0245] In summary, the method provided in this embodiment interrupts electrical compensation after power-off or after the user actively performs electrical compensation, and the display panel uses historical compensation voltage data to display the screen, thereby reducing the impact of electrical compensation interruption on the screen and meeting the user's need to continue watching the screen when electrical compensation is not currently required.

[0246] Figure 10 A flowchart illustrating an exemplary embodiment of this application is shown. The method is executed by a display device, which includes a system chip, a timing controller, and a display panel. Figure 7 Compared to the previous embodiment, it has the following different steps.

[0247] Step 1001: The system chip sends an interrupt signal to the timing controller.

[0248] In some embodiments, the system chip forwards an interrupt signal to the timing controller to instruct the timing controller to interrupt the first electrical compensation.

[0249] In some embodiments, the system chip sends a deterministic shutdown signal to the timing controller based on a third pre-configuration. Upon receiving both an interrupt signal and the deterministic shutdown signal, the timing controller controls the display panel to shut down.

[0250] The third pre-configuration is stored in the system chip and is used to configure the system chip to send a confirmed shutdown signal to the timing controller after forwarding the interrupt signal when it receives a shutdown signal. The confirmed shutdown signal is used to instruct the timing controller to control the display panel to shut down.

[0251] Step 1002: The system chip sends an interrupt signal to the timing controller.

[0252] In some embodiments, the system chip forwards an interrupt signal to the timing controller to instruct the timing controller to interrupt the second electrical compensation.

[0253] In some embodiments, the system chip, based on a second pre-configuration, does not send a definitive shutdown signal to the timing controller; if the timing controller receives an interrupt signal but does not receive a definitive shutdown signal, it uses historical compensation voltage data to control the display panel to display the screen.

[0254] The second pre-configuration is stored in the system chip and is used to configure the system chip not to send a confirmed shutdown signal to the timing controller after forwarding the interrupt signal if it does not receive a shutdown signal. The confirmed shutdown signal is used to instruct the timing controller to control the display panel to shut down.

[0255] Historical compensation voltage data is stored in the timing controller, which uses this data to control the voltage of each pixel on the display panel.

[0256] In summary, the method provided in this embodiment can save energy consumption of the display device by interrupting electrical compensation after power-off and turning off the display panel.

[0257] The method provided in this embodiment also reduces the impact of electrical compensation interruption on the screen by interrupting electrical compensation after the user actively performs electrical compensation and displaying the screen using historical compensation voltage data on the display panel, thus meeting the user's need to continue watching the screen even if electrical compensation is not currently required.

[0258] Figure 11 A flowchart illustrating an exemplary embodiment of this application is shown. The method is executed by a display device, which includes a system chip, a timing controller, and a display panel. Figure 7 Compared to the previous embodiment, it has the following different steps.

[0259] Step 1101: The system chip sends an interrupt signal to the timing controller.

[0260] In some embodiments, the system chip forwards an interrupt signal to the timing controller to instruct the timing controller to interrupt the first electrical compensation.

[0261] In some embodiments, the system chip, based on a first pre-configuration, does not send a definitive shutdown signal to the timing controller; when the timing controller receives an interrupt signal but does not receive a definitive shutdown signal, it uses historical compensated voltage data to control the display panel to display the screen.

[0262] The first pre-configuration is stored in the system chip and is used to configure the system chip not to send a confirmed shutdown signal to the timing controller after forwarding the interrupt signal when it receives a shutdown signal. The confirmed shutdown signal is used to instruct the timing controller to control the display panel to shut down.

[0263] Historical compensation voltage data is stored in the timing controller, which uses this data to control the voltage of each pixel on the display panel.

[0264] Step 1102: The system chip sends an interrupt signal to the timing controller.

[0265] In some embodiments, the system chip forwards an interrupt signal to the timing controller to instruct the timing controller to interrupt the second electrical compensation.

[0266] In some embodiments, the system chip sends a deterministic shutdown signal to the timing controller based on a fourth pre-configuration. Upon receiving both an interrupt signal and the deterministic shutdown signal, the timing controller controls the display panel to shut down.

[0267] The fourth pre-configuration is stored in the system chip and is used to configure the system chip to send a confirmed shutdown signal to the timing controller after forwarding the interrupt signal if it does not receive a shutdown signal. The confirmed shutdown signal is used to instruct the timing controller to control the display panel to shut down.

[0268] In summary, the method provided in this embodiment reduces the impact of electrical compensation interruption on the screen by interrupting electrical compensation after power-off and displaying the screen using historical compensation voltage data, thus meeting the user's need to re-view the screen when electrical compensation is not currently required.

[0269] The method provided in this embodiment can also save energy consumption of the display device by interrupting the electrical compensation after the user actively performs the electrical compensation and turning off the display panel.

[0270] Figure 12 A flowchart illustrating an exemplary embodiment of this application is shown. The method is executed by a display device, which includes a system chip, a timing controller, and a display panel. Figure 7 Compared to the previous embodiment, it has the following different steps.

[0271] Step 1201: The system chip sends an interrupt signal to the timing controller.

[0272] In some embodiments, the system chip forwards an interrupt signal to the timing controller to instruct the timing controller to interrupt the first electrical compensation or the second electrical compensation.

[0273] In some embodiments, the system chip sends a deterministic shutdown signal to the timing controller based on a third pre-configuration. Upon receiving both an interrupt signal and the deterministic shutdown signal, the timing controller controls the display panel to shut down.

[0274] The third pre-configuration is stored in the system chip and is used to configure the system chip to send a confirmed shutdown signal to the timing controller after forwarding the interrupt signal when it receives a shutdown signal. The confirmed shutdown signal is used to instruct the timing controller to control the display panel to shut down.

[0275] In some embodiments, the system chip sends a deterministic shutdown signal to the timing controller based on a fourth pre-configuration. Upon receiving both an interrupt signal and the deterministic shutdown signal, the timing controller controls the display panel to shut down.
