[0048] Currently, due to the rapid development of the display panel industry and the increasing demands of users for product size, more and more large-size, high-resolution display panel products are entering the market. At the same time, as the industry's requirements for environmental protection and power consumption continue to rise, the market's requirements for this type of display panel product are becoming increasingly stringent. Taking power consumption as an example, the European Union has put forward the most stringent power consumption requirements for 8K (7680x4320) TVs, causing product manufacturers to strive to reduce power consumption to meet the requirements. Among them, the larger the size and the higher the resolution of the display panel product, the more data driver chips (also known as COF) are used. Therefore, if the power consumption of COF can be effectively reduced, it will also have a significant effect on reducing the overall power consumption of the product.

[0049] Based on this, embodiments of this application provide a control method, apparatus, and display device for a display panel. In the control method, the current interval type is first obtained, including a display interval and a blank interval. When the interval type is the display interval, a delay interval is set according to the data control signal, the total duration of the current frame, and a preset delay percentage, reducing the power consumption of the display panel within the delay interval. When the interval type is the blank interval, the power consumption of the display panel within the blank interval is reduced. This application employs different technical means to reduce the power consumption of the display panel for different interval types, ensuring that the power consumption within the delay interval is reduced without significantly affecting the display effect during the display interval, while minimizing power waste caused by bias current during the blank interval. This effectively reduces the overall power consumption of the data driver chip throughout its operating time, ultimately achieving the goal of reducing product power consumption and overcoming the problem of excessively high power consumption in display panel products in related technologies.

[0050] The control method, apparatus, and display device for the display panel provided in this application are specifically described through the following embodiments. First, the control method for the display panel in the embodiments of this application is described.

[0051] This application provides a method for controlling a display panel, referring to... Figure 1 , Figure 1 This is a flowchart illustrating a control method for a display panel according to an embodiment of this application. This control method can be applied to display devices, such as... Figure 1 As shown, the control method for the display panel provided in this embodiment includes steps S10, S21 and S22.

[0052] Step S10: Obtain the interval type at the current time, where the interval type includes a display interval and a blank interval;

[0053] It should be noted that in this embodiment, the execution entity is the data driver chip COF in the display panel, which is connected to the TCON (logic board) in the display panel. After receiving the TP signal (source data latch signal) output by the TCON, the data driver chip begins to execute the display panel control method provided in this embodiment. When the falling edge of the latch signal arrives, the data driver chip starts to output data (S-OUT). At this time, the data driver chip needs to supply load to the in-plane (or deload load from the in-plane to the data driver chip), which will generate a load current. Since the in-plane display controls the polarity change by applying voltage changes to the liquid crystal electrode and pixel electrode, when the polarity changes, Iac can be deloaded from the in-plane to the data driver chip or flow from the in-plane to the data driver chip. Therefore, this load current Iac is called AC (alternating current). When displaying a lightly loaded image, the required current is small. Therefore, the current existing in the blanking time (i.e., blank interval) at the end of the display is often used to supply the load. This current is smaller and more stable than Iac. We call this current Ibias the bias current. Figure 2 When displaying a heavy-load scene (such as H-line, where one line of white is bright at 255 and the other line of black is dark), the falling edge of the latch signal controls the data driver chip to start outputting. The output current signal includes AC current and bias current. The AC current is used to ensure that the screen output reaches the voltage level faster to correctly display the white horizontal line, while the bias current is used to ensure stable load supply when displaying the black horizontal line. When displaying a light-load scene (such as Mosaic), the falling edge of the latch signal controls the data driver chip to only provide bias current for load supply. The purpose of this embodiment is to reduce the overall power consumption of the data driver chip to reduce the power consumption of the product. The specific technical means adopted is to reduce the bias current of the data driver chip. However, while reducing power consumption, the impact of the display screen must also be considered. Therefore, this embodiment uses the interval type as a prerequisite and uses different methods to reduce the bias current for the display interval and the blank interval, so that the impact of this technical means on the screen display is minimized.

[0054] Step S21: When the interval type is the display interval, a delay interval is set according to the data control signal, the total duration of the current frame and the preset delay ratio to reduce the power consumption of the display panel in the delay interval.

[0055] In this embodiment, the step of reducing the power consumption of the display panel during the delay interval includes:

[0056] Reduce the bias current of the data driver chip within the delay interval to reduce the power consumption of the display panel within the delay interval.

[0057] Reference Figure 3 In related technologies, traditional display panels do not change the magnitude of the bias current. When the displayed image is in the display range, upon the rising edge of the latch signal, the data driver chip latches the data to be output and the POL polarity switching signal. Upon the falling edge of the latch signal, the data driver chip is controlled to output the latched data. Figure 3 The bias current in the circuit did not change within one control cycle.

[0058] Reference Figure 4 The technical solution presented in this embodiment is that when the falling edge of the latch signal arrives, although the data driver chip receives the falling edge signal, it will not output immediately. Instead, it will control the data to be output after a certain period of time. For example, a certain register position r1 is occupied inside the data driver chip IC. When the data driver chip reads the arrival of the falling edge of the latch signal, it sends the signal to r1. r1 controls the output to be delayed by 500ns. After the timing time reaches 500ns, the data is then controlled to be output. During the 500ns delay, the data driver chip also reduces the bias current. Therefore, the total bias current is reduced throughout the entire data output cycle, and the overall power consumption of the data driver chip is also reduced. The data driver chip controls the data to be output with a 500ns delay, which shortens the overall output time (i.e., shortens the time for charging the pixel capacitor). However, since the delay time accounts for a small proportion of the overall charging time, the impact on the screen display is very small.

[0059] In some feasible embodiments, the step S21 of setting the delay interval based on the data control signal, the total duration of the current frame, and the preset delay percentage may specifically include:

[0060] Step S210: When the falling edge of the data control signal arrives, a delay interval is set based on the total duration of the current frame and the preset delay ratio.

[0061] Reference Figure 5As an example, step S210, which involves setting the delay interval based on the total duration of the current frame and the preset delay percentage, may specifically include:

[0062] Step S211: Set the product of the total duration of the current frame and the preset delay percentage as the maximum delay threshold;

[0063] Step S212: Set the arrival time of the falling edge of the data control signal as the minimum value of the delay interval;

[0064] Step S213: The sum of the minimum value and the maximum delay threshold is set as the maximum value of the delay interval.

[0065] It is understandable that the data driver chip can know the total duration of the current frame based on the latch signal from TCON. The preset delay percentage can be obtained after multiple experiments and tests on actual products, such as 0.5%, 1%, etc. This embodiment does not limit this. As long as the ratio obtained by using the total duration as the denominator and the delay time as the numerator is less than the preset delay percentage, then this delay time can be used as the time span of the delay interval. Taking 500ns as the maximum delay threshold as an example, it is also feasible to set only 400ns as the time span of the delay interval. However, the shorter the delay, the shorter the time for the bias current to decrease, and the less power consumption is reduced.

[0066] Step S22: When the interval type is the blank interval, reduce the power consumption of the display panel in the blank interval.

[0067] In this embodiment, the step of reducing the power consumption of the display panel within the blank area includes:

[0068] Reduce the bias current of the data driver chip in the blank area to reduce the power consumption of the display panel in the blank area.

[0069] Reference Figure 6The technical solution provided in this embodiment is to reduce the bias current in the blank interval. Specifically, the data driver chip controls the output screen to be displayed within the display time. After each frame is displayed, there is a blank time during which the IC performs a reset or other operations. Therefore, the current of the data driver chip during this time is also the bias current. This embodiment reduces the bias current in the blank interval after the display interval of each frame, so that the power consumption of the data driver chip is minimized throughout the entire operation. First, the register (rm) inside the data driver chip is used to set the function of reducing the bias current in the blank interval to be enabled or disabled. When the data driver chip detects that a frame has ended and entered the blank interval, it will feed back this detection result to the register of the function switch. The register will then control the reduction of the bias current of the data driver chip. When the data driver chip detects that the next frame of display data has started to be output, it will feed back this detection result to the register again. At this time, the register will control the data driver chip to restore the original bias current.

[0070] In some feasible embodiments, prior to step S10 above, the control method for the display panel further includes:

[0071] Step S01: Obtain the operating temperature of the data driver chip;

[0072] Step S02: Determine the frame type corresponding to the current frame based on the operating temperature. The frame type includes heavy load frame and light load frame.

[0073] Step S03: Determine whether to reduce the bias current of the data driver chip based on the screen type.

[0074] It should be noted that the control method of the display panel provided in the above embodiments does not take into account whether the display screen is a heavily loaded or lightly loaded screen. For all load conditions, the technical means of reducing bias current corresponding to the interval type will be adopted to reduce power consumption. However, this embodiment takes into account that the magnitude of bias current under heavy load and light load screen is different. Therefore, it is considered that, based on the above embodiments, it is possible to decide whether to adopt the power reduction technical solution provided in the above embodiments based on the display screen under different load conditions.

[0075] It is understood that the basis for judging the light and heavy load screen in this embodiment is the operating temperature of the data driver chip. The temperature can be directly collected by a temperature sensor, or it can be calculated by detecting the resistance value of the temperature compensation resistor in the data driver chip. This embodiment does not limit the specific temperature acquisition method.

[0076] In some feasible embodiments, step S02 above may specifically include:

[0077] Step S021: If the operating temperature is greater than or equal to the first preset temperature, determine that the frame type corresponding to the current frame is a reloaded frame.

[0078] Step S022: If the operating temperature is less than or equal to the second preset temperature, determine that the current frame corresponds to a light load frame.

[0079] Wherein, the first preset temperature is greater than the second preset temperature.

[0080] It is understandable that this embodiment uses the operating temperature of the data driver chip as the basis for distinguishing between heavy-load and light-load screens. Therefore, a corresponding temperature threshold needs to be set to determine whether the current display screen is a heavy-load or light-load screen.

[0081] As an example, the first preset temperature can be 100 degrees Celsius, and the second preset temperature can be 50 degrees Celsius.

[0082] As an example, the first preset temperature can be 90 degrees Celsius, and the second preset temperature can be 60 degrees Celsius.

[0083] In some feasible embodiments, step S03 above may specifically include:

[0084] Step S031: If the screen type is the overloaded screen, then execute step S10;

[0085] Step S032: If the screen type is the light-load screen, return to step S01.

[0086] This embodiment selects to enable the display panel control method provided in the above embodiment under heavy load screen conditions to reduce the bias current in the display area and blank area under heavy load screen conditions, thereby reducing the power consumption of the data driver chip under heavy load screen conditions; while under light load screen conditions, the display panel control method provided in the above embodiment is not enabled, because the bias current intensity under light load screen conditions is already smaller than that under heavy load screen conditions, and enabling the software control scheme provided in the above embodiment will also generate less power consumption. The overall power consumption reduction after enabling the scheme is not very significant, so it can be selected to enable or not enable.

[0087] This embodiment provides a control method for a display panel. First, the interval type at the current moment is obtained, including display intervals and blank intervals. Then, when the interval type is the display interval, a delay interval is set based on the data control signal, the total duration of the current frame, and a preset delay ratio, reducing the bias current of the data driver chip within the delay interval. When the interval type is the blank interval, the bias current of the data driver chip is reduced to lower the overall power consumption of the data driver chip. This application employs different technical means to reduce the bias current of the data driver chip for different interval types, ensuring that power consumption is reduced within the delay interval without significantly affecting the display effect during the display interval, and minimizing power waste caused by bias current during the blank interval. This effectively reduces the overall power consumption of the data driver chip throughout its operating time, ultimately achieving the goal of reducing product power consumption. This overcomes the problem of excessively high power consumption in display panel products in related technologies and effectively enhances product competitiveness.

[0088] Furthermore, embodiments of this application also propose a control device for a display panel, referring to... Figure 7 , Figure 7 This is a schematic diagram of the structure of a control device for a display panel provided in an embodiment of this application, as shown below. Figure 7 As shown, in this embodiment, the control device for the display panel includes: an acquisition module 100 and an execution module 200.

[0089] The acquisition module 100 is used to acquire the interval type at the current time, and the interval type includes display interval and blank interval;

[0090] The execution module 200 is used to set a delay interval based on the data control signal, the total duration of the current frame, and the preset delay ratio when the interval type is the display interval, thereby reducing the power consumption of the display panel within the delay interval;

[0091] The execution module 200 is also used to reduce the power consumption of the display panel in the blank interval when the interval type is the blank interval.

[0092] In some feasible embodiments, the execution module 200 is further configured to set a delay interval based on the total duration of the current frame and a preset delay percentage when the falling edge of the data control signal arrives.

[0093] In some feasible embodiments, the execution module 200 is further configured to set the product of the total duration of the current frame and the preset delay ratio as the maximum delay threshold; set the arrival time of the falling edge of the data control signal as the minimum value of the delay interval; and set the sum of the minimum value and the maximum delay threshold as the maximum value of the delay interval.

[0094] In some feasible embodiments, the execution module 200 is also configured to reduce the bias current of the data driver chip in the delay interval, so as to reduce the power consumption of the display panel in the delay interval.

[0095] In some feasible embodiments, the execution module 200 is also used to reduce the bias current of the data driver chip in the blank area, so as to reduce the power consumption of the display panel in the blank area.

[0096] In some feasible embodiments, the acquisition module 100 is also used to acquire the operating temperature of the data driver chip; determine the frame type corresponding to the current frame based on the operating temperature, the frame type including heavy load frame and light load frame; and determine whether to reduce the bias current of the data driver chip based on the frame type.

[0097] In some feasible embodiments, the acquisition module 100 is further configured to determine that the current frame corresponds to a heavy load frame when the operating temperature is greater than or equal to a first preset temperature; and to determine that the current frame corresponds to a light load frame when the operating temperature is less than or equal to a second preset temperature; wherein the first preset temperature is greater than the second preset temperature.

[0098] In some feasible embodiments, the execution module 200 is further configured to perform the step of obtaining the interval type of the current time when the screen type is the heavy screen; and return to perform the step of obtaining the operating temperature of the data driver chip when the screen type is the light screen.

[0100] Furthermore, this application embodiment also provides a display device. The control method applied to the display panel of the display device described above can be executed by a control device for the display panel. This control device can be implemented by software and / or hardware and integrated into the display device. The display panel in the display device can be a Tn (Twistednematic) display panel, an IPS (In-Plane Switching) display panel, a VA (Vertical Alignment) display panel, or an mVA (multi-Domain Vertical Alignment) display panel. Of course, it can also be other types of display panels, such as an OLED (Organic Light-Emitting Diode) display panel.
