Description

Technical Field

[0001] This application relates to screen display technology. More specifically, it relates to a display device and a method for partitioned display. Background Technology

[0002] In the field of screen display technology, due to the increasing number of terminal application scenarios, traditional display devices maintain a specific refresh rate for a long time when displaying, which will cause a certain degree of power consumption waste.

[0003] In related technologies, panel power consumption is reduced by using automatic current control (ACC) to reduce grayscale data output. Alternatively, power consumption can be reduced by powering off the source driver chip during blanking. However, neither of these solutions can achieve a significant reduction in power consumption while the screen is displaying normally. Summary of the Invention

[0004] To solve the above-mentioned technical problems, or at least partially solve them, embodiments of this application provide a display device and a partitioned display method.

[0005] In a first aspect, embodiments of this application provide a display device, including:

[0006] A display panel with multiple display zones;

[0007] The controller connected to the plurality of display zones is configured to:

[0008] Based on the multiple current display images and multiple historical display images corresponding to the multiple display partitions, determine the first source driver identifier corresponding to the dynamic display partition among the multiple display partitions, and the enable identifier of the partition control module corresponding to the multiple display partitions;

[0009] The refresh rate and grayscale of the plurality of display partitions are controlled according to the enable flag and the first source driver flag.

[0010] In this embodiment, the display panel of the display device is composed of multiple display partitions. The controller connected to these multiple display partitions can determine the source driver identifier corresponding to the display partition that needs to be dynamically displayed, as well as the enable identifier of the partition control module corresponding to each display partition, based on the current display image and the historical display image of each display partition. Then, based on the source driver identifier and the enable identifier of the partition control module, the refresh rate and grayscale of the display partition are controlled. This realizes the joint control of refresh rate and grayscale by enabling the partition control module and adjusting the output of the corresponding source driver chip under different screen application scenarios. Thus, while ensuring the image display quality, low-power display control that conforms to the current screen application scenario is achieved.

[0011] In some embodiments of this application, the plurality of display partitions are arranged in a grid pattern, with display partitions in the same row corresponding to the same partition control module, and display partitions in the same column corresponding to the same source driver chip.

[0012] In some embodiments of this application, the controller is specifically configured as follows:

[0013] Among the multiple display rows included in the display panel, a dynamic display row is determined based on the multiple currently displayed images and the multiple historical display images;

[0014] Among the candidate display partitions included in the dynamic display row, the dynamic display partition is determined based on the current display image and the historical display image corresponding to the candidate display partition;

[0015] The source driver identifier corresponding to the dynamic display partition is determined as the first source driver identifier.

[0016] In some embodiments of this application, the controller is specifically configured as follows:

[0017] For each of the displayed rows, the row image similarity corresponding to the displayed row is determined based on the current displayed image and the historical displayed image corresponding to the displayed row;

[0018] Among the plurality of display rows, the display rows whose row image similarity is less than a first preset threshold are determined as the dynamic display rows.

[0019] In some embodiments of this application, the controller is specifically configured as follows:

[0020] The current row image is obtained by stitching together multiple currently displayed images from multiple display partitions within the display row, and the historical row image is obtained by stitching together multiple historical displayed images from multiple display partitions within the display row.

[0021] Calculate the similarity between the current row image and the historical row images to obtain the row image similarity.

[0022] In some embodiments of this application, the controller is specifically configured as follows:

[0023] Determine the current refresh rate and the previous refresh rate for each of the aforementioned display partitions;

[0024] If the previous refresh rate of the display partition and the current refresh rate meet a preset matching condition, then the initial enable flag of the display partition is determined to be a disable flag.

[0025] If the previous refresh rate of the display partition does not meet the preset matching condition with the current refresh rate, then the initial enable flag of the display partition is determined as the enable flag.

[0026] For each partition control module, if the initial enable flag of the display partition corresponding to the partition control module is the off flag, then the enable flag of the partition control module is determined to be the off flag; otherwise, the enable flag of the partition control module is determined to be the on flag.

[0027] In some embodiments of this application, the controller is specifically configured as follows:

[0028] Send the corresponding enable flags to each zone control module;

[0029] For each of the aforementioned dynamic display partitions, the current display image corresponding to the dynamic display partition is sent to the first source driver chip with the corresponding first source driver identifier, so that the dynamic display partition displays the current display image at the current refresh rate.

[0030] In some embodiments of this application, the controller is further configured to:

[0031] For each static display partition, an adjustment image corresponding to the static display partition is sent to the corresponding second source driver chip so that the static display partition displays the adjustment image at the current refresh rate; wherein, the adjustment image is determined by reducing the grayscale of the current display image corresponding to the static display partition.

[0032] In some embodiments of this application, the output of the controller is set based on an end-to-end protocol, and the controller is further configured to:

[0033] Determine the first currently displayed image and the first historical displayed image of the first display partition;

[0034] If the image similarity between the first currently displayed image and the first historically displayed image is greater than the second preset threshold, then the accumulated value corresponding to the first display partition is accumulated to obtain a new accumulated value.

[0035] If the new accumulated value is greater than the quantity threshold, the control word of the end-to-end protocol is adjusted to disable the function, resulting in an updated control word. The updated control word is then sent to the source driver chip corresponding to the first display partition, so that the source driver chip corresponding to the first display partition disables the target function corresponding to the updated control word.

[0036] Secondly, embodiments of this application provide a partitioned display method applied to a display device, the display device including a display panel having multiple display partitions and a controller connected to the multiple display partitions, the method including:

[0037] Based on the multiple current display images and multiple historical display images corresponding to the multiple display partitions, determine the first source driver identifier corresponding to the dynamic display partition among the multiple display partitions, and the enable identifier of the partition control module corresponding to the multiple display partitions;

[0038] The refresh rate and grayscale of the plurality of display partitions are controlled according to the enable flag and the first source driver flag.

[0039] Thirdly, embodiments of this application provide a computer-readable storage medium, including: storing a computer program on the computer-readable storage medium, wherein when the computer program is executed by a processor, it implements the partitioned display method as shown in the second aspect.

[0040] Fourthly, embodiments of this application provide a computer program product, including: when the computer program product is run on a computer, causing the computer to implement the partitioned display method as shown in the second aspect. Attached Figure Description

[0054] To make the objectives and implementation methods of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments.

[0055] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0056] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0057] The terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0058] The display device provided in this application can have various implementation forms, such as a television, a smart television, a laser projection device, a monitor, an electronic bulletin board, an electronic table, a mobile phone, a tablet computer, a laptop computer, a handheld computer, an in-vehicle electronic device, etc.

[0059] Figure 1 This is a schematic diagram illustrating an operational scenario between a display device and a control device according to an embodiment, wherein the control device includes a smart device or a control apparatus. Figure 1 As shown, the user can operate the display device 200 through the smart device 300 or the control device 100.

[0060] In some embodiments, the control device 100 may be a remote control. Communication between the remote control and the display device includes infrared protocol communication, Bluetooth protocol communication, and other short-range communication methods, controlling the display device 200 wirelessly or via wired means. Users can control the display device 200 by inputting user commands through buttons on the remote control, voice input, control panel input, etc.

[0061] In some embodiments, a smart device 300 (such as a mobile terminal, tablet computer, computer, laptop computer, etc.) can also be used to control the display device 200. For example, an application running on the smart device can be used to control the display device 200.

[0062] In some embodiments, the display device may receive instructions not through the aforementioned smart devices or control devices, but through touch or gestures.

[0063] In some embodiments, the display device 200 can also be controlled in ways other than the control device 100 and the smart device 300. For example, it can be controlled by directly receiving the user's voice commands through a module configured inside the display device 200 for acquiring voice commands, or it can be controlled by receiving the user's voice commands through a voice control device set outside the display device 200.

[0064] In some embodiments, the display device 200 also communicates with the server 400. The display device 200 may communicate via a local area network (LAN), wireless local area network (WLAN), and other networks. The server 400 may provide various content and interactive features to the display device 200. The server 400 may be a cluster or multiple clusters, and may include one or more types of servers.

[0065] Figure 2 An exemplary block diagram of the configuration of the control device 100 according to an exemplary embodiment is shown. Figure 2 As shown, the control device 100 includes a controller 110, a communication interface 130, a user input / output interface 140, an external memory, and a power supply. The control device 100 can receive user input operation commands and convert the operation commands into commands that the display device 200 can recognize and respond to, thus acting as an intermediary for interaction between the user and the display device 200.

[0066] like Figure 3 The display device 200 includes at least one of the following: a tuner 210, a communicator 220, a detector 230, an external device interface 240, a controller 250, a display 260, an audio output interface 270, a user interface 280, an external memory, and a power supply.

[0067] In some embodiments, the controller includes a processor, a video processor, an audio processor, a graphics processor, RAM, ROM, and a first interface to an nth interface for input / output.

[0068] The display 260 includes a display screen assembly for presenting images, a driving assembly for driving image display, a component for receiving image signals from the controller output, and a user interface for displaying video content, image content, menu control interface, and user control UI.

[0069] The display 260 can be an LCD display, an OLED display, or a projection display, and can also be a projection device and a projection screen.

[0070] The communicator 220 is a component used to communicate with external devices or servers according to various communication protocol types. For example, the communicator may include at least one of the following: a Wi-Fi module, a Bluetooth module, a wired Ethernet module, other network communication protocol chips or near-field communication protocol chips, and an infrared receiver. The display device 200 can establish the transmission and reception of control signals and data signals with the external control device 100 or the server 400 through the communicator 220.

[0071] User interface 280 can be used to receive control signals from control device 100 (such as an infrared remote control). It can also be used to directly receive user input operation commands and convert the operation commands into commands that display device 200 can recognize and respond to; in this case, it can be called a user input interface.

[0072] Detector 230 is used to collect signals from the external environment or to interact with the external environment. For example, detector 230 includes a light receiver, a sensor for collecting ambient light intensity; or, detector 230 includes an image acquisition device, such as a camera, which can be used to collect external environmental scenes, user attributes, or user interaction gestures; or, detector 230 includes a sound acquisition device, such as a microphone, for receiving external sounds.

[0073] The external device interface 240 may include, but is not limited to, one or more of the following: High Definition Multimedia Interface (HDMI), analog or high-definition component input interface (component), composite video input interface (CVBS), USB input interface (USB), RGB port, etc. It may also be a composite input / output interface formed by multiple interfaces mentioned above.

[0074] The tuner / demodulator 210 receives broadcast television signals via wired or wireless means, and demodulates audio and video signals, such as EPG data signals, from multiple wireless or wired broadcast television signals.

[0075] In some embodiments, the controller 250 and the tuner 210 may be located in different separate devices, that is, the tuner 210 may also be located in an external device of the main device where the controller 250 is located, such as an external set-top box.

[0076] The controller 250 controls the operation of the display device and responds to user operations through various software control programs stored in memory (internal or external memory). The controller 250 controls the overall operation of the display device 200. For example, in response to receiving a user command to select a UI object to display on the monitor 260, the controller 250 can perform operations related to the object selected by the user command.

[0077] In some embodiments, the controller includes at least one of a central processing unit (CPU), a video processor, an audio processor, a graphics processing unit (GPU), and random access memory (RAM), read-only memory (ROM), a first to an nth interface for input / output, a communication bus, etc.

[0078] RAM, also known as main memory, is an internal memory that directly exchanges data with the controller. It can be read and written at any time (except during refresh) and is very fast, typically serving as temporary data storage for the operating system or other running programs. Its biggest difference from ROM is data volatility; data stored in RAM is lost when power is off. RAM is used in computers and digital systems to temporarily store programs, data, and intermediate results. ROM operates in a non-destructive read-only manner, allowing only reading and not writing. Once information is written, it is fixed and will not be lost even if power is cut off; therefore, it is also called fixed-function memory.

[0079] Users can input commands through a graphical user interface (GUI) displayed on the monitor 260, and the user input interface receives the user input commands through the GUI. Alternatively, users can input commands by entering specific sounds or gestures, and the user input interface receives the user input commands by recognizing the sounds or gestures through sensors.

[0080] A "user interface" is the medium through which an application or operating system interacts and exchanges information with the user. It converts information from its internal form to a form that the user can accept. A common form of user interface is the graphical user interface (GUI), which refers to a user interface related to computer operation displayed graphically. It can be an icon, window, control, or other interface element displayed on the screen of a display device. Controls can include visual interface elements such as icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, and widgets.

[0081] In the field of screen display technology, with the continuous increase in terminal application scenarios, traditional display devices do not have dynamic refresh rate adjustment for some dynamic and static images. Therefore, the display panel as a whole maintains a specific refresh rate for a long time without reducing the refresh rate of non-critical display areas through zone detection, which results in a certain degree of waste of panel power consumption and driver power consumption.

[0082] In related technologies, power consumption can be reduced by detecting overloaded frames. Specifically, by detecting overloaded and non-overloaded frames on the panel in certain application scenarios, power consumption can be reduced by adjusting the output grayscale data of the automatic current control meter or modifying the inversion method. However, this method is difficult to detect complex changes in static and dynamic frames, the accuracy is hard to guarantee, and the power consumption reduction effect is not significant enough. When the frame changes, it is necessary to determine whether it is a dynamic frame based on several consecutive frames. In some complex application scenarios, the transition between static and dynamic frames may be frequent or a specific refresh rate may be required, and this method's refresh rate adjustment is not timely enough.

[0083] Alternatively, power consumption can be reduced by leveraging energy savings during frame blanking. Specifically, the Timing Controller (TCON) can output a wake-up signal to the Source Driver chip every frame via a hardware pin. During blanking periods when no data is being received, the Timing Controller pulls the wake-up signal low. Upon receiving the low signal, the Source Driver chip powers off and shuts down its receiver (RX). Simultaneously, the Timing Controller shuts down its transmitter (TX), stops outputting data, and enters standby mode. When data reception is needed during active periods, the Timing Controller restores the wake-up signal to a high level. At this time, the Timing Controller powers on its transmitter and outputs data, and the Source Driver chip powers on again to begin receiving and outputting data. In the above scheme, for screen partitions that maintain a high or low refresh rate for extended periods, the Source Driver chip will still be woken up every frame for power-on and power-off cycles, resulting in unnecessary drive power consumption. Secondly, during the power-on and power-off processes of the source driver chip, the timing controller needs to pull the wake-up signal high before the blanking period ends to ensure that the source driver chip has sufficient time to lock. Before the wake-up signal goes low and before the source driver chip needs to be powered off, time needs to be reserved to ensure complete transmission of display data. Since the sensitivity and mechanisms of existing source driver chips may differ, the required time cannot be precisely set, thus posing a risk that the source driver chip may not be able to wake up properly and that data transmission may be incomplete.

[0084] None of the above solutions can achieve a significant reduction in power consumption while the screen is displaying normally.

[0085] To address the aforementioned problems, this application provides a display device and a partitioned display method. The display device can implement the partitioned display method provided in this application embodiment, or a functional module or entity within the display device can implement the partitioned display method provided in this application embodiment. The display device includes a controller, which can correspond to the above-mentioned... Figure 3The controller 250 in the display device can be a corresponding timing controller.

[0086] This application provides a display device, including: a display panel having multiple display zones; and a controller connected to the multiple display zones, configured to: determine a first source driver identifier corresponding to a dynamic display zone among the multiple display zones, and an enable identifier for a partition control module corresponding to the multiple display zones, based on multiple current display images and multiple historical display images corresponding to the multiple display zones; and control the refresh rate and grayscale of the multiple display zones based on the enable identifier and the first source driver identifier.

[0087] The display partitions can be independent display units obtained by dividing the display panel into physical areas. Each display partition can have its refresh rate, grayscale, and other display control parameters adjusted independently. The display panel can be a device that converts electrical signals into visible images. The controller can be a timing controller that controls multiple display partitions. The current display image can be the image that needs to be displayed on the display partition, and there can be a one-to-one correspondence between the current display image and the display partition. The historical display images can be images that have already been displayed in the display partitions; these historical display images can be the previous frame or several frames above the current display image. The dynamic display partitions can be display partitions that display images dynamically; understandably, the image changes significantly within these dynamic display partitions. These dynamic display partitions can be determined based on dynamic image detection using the current display image and historical display images.

[0088] The first source driver identifier can be the source driver identifier corresponding to the dynamic display partition. The source driver identifier is used to uniquely identify the source driver chip in the display device. The source driver chip is used to convert input image data into pixel-recognizable drive signals. The partition control module, also known as the array substrate row driver (Gate-On-Array, GOA) module, is used to control the gating and scanning timing of pixel rows on the display panel. The enable identifier can be used to indicate the activation or deactivation of the partition control module. The refresh rate is the frequency at which the display partition refreshes the image. Grayscale represents the brightness level of a pixel.

[0089] In this embodiment, the display panel of the display device includes multiple display zones, which are controlled by a controller. The controller can determine the current display image and historical display image corresponding to each display zone. The controller can determine whether the refresh rate of each display zone needs adjustment based on the current and historical display images, and determine the enable flag of the zone control module based on the refresh rate adjustment result. Furthermore, the controller can determine whether each display zone is a dynamic display zone based on the current and historical display images, and determine a first source driver flag for controlling the dynamic display zone.

[0090] In this embodiment, the display panel of the display device is composed of multiple display partitions. The controller connected to these multiple display partitions can determine the source driver identifier corresponding to the display partition that needs to be dynamically displayed, as well as the enable identifier of the partition control module corresponding to each display partition, based on the current display image and the historical display image of each display partition. Then, based on the source driver identifier and the enable identifier of the partition control module, the refresh rate and grayscale of the display partition are controlled. This realizes the joint control of refresh rate and grayscale by enabling the partition control module and adjusting the output of the corresponding source driver chip under different screen application scenarios. Thus, while ensuring the image display quality, low-power display control that conforms to the current screen application scenario is achieved.

[0091] In some embodiments of this application, multiple display partitions are arranged in a grid pattern, with display partitions in the same row corresponding to the same partition control module, and display partitions in the same column corresponding to the same source driver chip.

[0092] Among them, the grid arrangement can be a matrix arrangement with multiple rows and columns.

[0093] In this embodiment, the display zones in the display panel are arranged in a grid pattern, with each row corresponding to a zone control module and each column corresponding to a source driver chip. The zone control module can control whether to adjust the refresh rate of the display zones in the corresponding row. Specifically, the zone control module can simultaneously control whether to update the refresh rate of multiple display zones in the same row. Understandably, the refresh rates of multiple display zones in the same row are updated to corresponding values ​​simultaneously, which can be the same or different. The source driver chip can adjust the grayscale and other dimensions of the displayed image of the display zones in the corresponding column. Specifically, the source driver chip can control the grayscale of multiple display zones in the same column separately. Understandably, the grayscale of the image of multiple display zones in the same column can be set individually. Thus, this arrangement achieves joint control of the refresh rate, grayscale, and other dimensions of the image displayed by the display zones through the zone control module and the source driver chip, laying the foundation for reducing panel power consumption and driver power consumption.

[0094] In some embodiments of this application, the controller is specifically configured to: determine a first source driver identifier corresponding to a dynamic display partition among the multiple display partitions based on multiple current display images and multiple historical display images corresponding to multiple display partitions, including: determining a dynamic display row among multiple display rows included in the display panel based on multiple current display images and multiple historical display images; determining a dynamic display partition among candidate display partitions included in the dynamic display row based on current display images and historical display images corresponding to the candidate display partitions; and determining the source driver identifier corresponding to the dynamic display partition as the first source driver identifier.

[0095] A display row can include multiple display partitions located on the same row. A dynamic display row can be a display row for displaying dynamic images; understandably, the images within this dynamic display row change significantly. Candidate display partitions can be the display partitions included in the dynamic display row.

[0096] In this embodiment, the controller can first determine the dynamic display area based on the display row as the basic unit, according to the current display image and the historical display image corresponding to each display row, thus obtaining dynamic display rows. The display partitions included in the dynamic display rows are determined as candidate display partitions. The dynamic display partition is then determined based on the similarity between the current display image and the historical display image corresponding to the candidate display partition. This embodiment does not limit the calculation method of this similarity. The source driver identifier corresponding to the dynamic display partition is then determined as the first source driver identifier. Figure 4 A schematic diagram illustrating the determination of dynamic display partitions according to some embodiments is shown, such as Figure 4As shown, GOA1 to GOAN represent the 1st to Nth partition control modules, and Driver1 to Driver6 represent the 1st to 6th source driver chips. A0 to AN, B0 to BN, C0 to CN, D0 to DN, E0 to EN, and F0 to FN represent the 0th to Nth display partitions in columns A to F, respectively. Figure 4 In this system, the controller can receive the currently displayed image and historical displayed images, and determine the dynamic display partitions based on these images through still frame detection. It then controls the partition control module through partition control and controls the source driver chip through its output. For example... Figure 4 As shown, each of the display partitions B2-B4, C2-C4, D2-D4, and E2-E4, represented by the shaded area, is a dynamic display partition.

[0097] In the above scheme, dynamic display rows are first determined on a row-by-row basis, narrowing the scope of dynamic display partition determination. Then, dynamic display partitions are determined on a partition-by-partition basis within the dynamic display partitions. This avoids determining whether each display partition in the display panel is a dynamic display partition, improving the efficiency of dynamic display partition determination and reducing the computing resources consumed in determining dynamic display partitions.

[0098] In some embodiments of this application, the controller is specifically configured to: determine dynamic display rows among multiple display rows included in the display panel based on multiple current display images and multiple historical display images, including: for each display row, determining the row image similarity corresponding to the display row based on the current display image and historical display image corresponding to the display row; and among the multiple display rows, determining the display rows with a row image similarity less than a first preset threshold as dynamic display rows.

[0099] Among them, row image similarity can be used to characterize the degree of similarity between adjacent images displayed in a row. The first preset threshold can be a pre-set threshold used to determine whether a display row is a dynamically displayed row.

[0100] In this embodiment, for each display row, the controller can determine the row image similarity based on the current display image and historical display images corresponding to the display partitions included in the display row. Furthermore, it determines whether the row image similarity is greater than a first preset threshold. If so, the display row is determined as a dynamic display row; otherwise, it is not a dynamic display row.

[0101] In some embodiments of this application, the controller is specifically configured to: determine the row image similarity corresponding to the display row based on the current display image and the historical display image corresponding to the display row, including: stitching together multiple current display images of multiple display partitions within the display row to obtain the current row image, and stitching together multiple historical display images of multiple display partitions within the display row to obtain the historical row image; calculating the similarity between the current row image and the historical row image to obtain the row image similarity.

[0102] The current row image can be the image that needs to be displayed on the current display row, and there can be a one-to-one correspondence between the current row image and the display row. The historical row image can be an image that has already been displayed on the display row, and the historical row image can be the previous frame or several frames above the current row image.

[0103] Figure 5 A schematic diagram of the display control architecture according to some embodiments is shown, such as Figure 5 As shown, after the data from the front end of each row arrives, it enters the still frame detection module. This module stitches the current display image of the display partition within that row, based on the display row as the basic unit, to obtain the current row image; and stitches the historical display images of the display partition within that row, to obtain the historical row image. Further, it calculates whether the current row image is the same as the historical row image of the previous frame. If so, it means that the row data does not need to be updated; otherwise, it means that the row data needs to be updated. This row is then identified as a dynamic display row, the dynamic display partition within that row is determined, and an update signal (UpdateEn) including the current display image is output to the polarity control module in the controller for identification.

[0104] In some embodiments of this application, the controller is specifically configured to: determine the enable flags of the partition control modules corresponding to the multiple display partitions based on the multiple current display images and multiple historical display images corresponding to the multiple display partitions, including: determining the current refresh rate and the previous refresh rate corresponding to each display partition; if the previous refresh rate and the current refresh rate of the display partition meet a preset matching condition, then the initial enable flag of the display partition is determined to be a disabled flag; if the previous refresh rate and the current refresh rate of the display partition do not meet the preset matching condition, then the initial enable flag of the display partition is determined to be an enabled flag; for each partition control module, if the initial enable flags of the display partitions corresponding to the partition control module are all disabled flags, then the enable flag of the partition control module is determined to be a disabled flag, otherwise the enable flag of the partition control module is determined to be an enabled flag.

[0105] The current refresh rate can be the refresh rate matched to the currently displayed image. This embodiment does not limit the current refresh rate; for example, it can be 120Hz or 24Hz. The previous refresh rate can be the refresh rate currently applied to the corresponding display partition. The preset matching condition can be a condition used to determine whether the refresh rate can be updated. This embodiment does not limit the preset matching condition; for example, the preset matching condition can be that the current refresh rate and the previous refresh rate are the same. The initial enable flag may be an enable flag determined based on a single display partition. The off flag can indicate that the partition control module is off, thus preventing refresh rate updates for the display partitions controlled by the partition control module. The on flag can indicate that the partition control module is on, thus updating the refresh rate of the corresponding display partition to the current refresh rate.

[0106] In this embodiment, the controller can obtain the current refresh rate of the display partition as the previous refresh rate. Furthermore, for each display partition, the current refresh rate is determined based on the degree of change between the current displayed image and the historical displayed image. Further, for each display partition, it is determined whether the current refresh rate and the previous refresh rate of that display partition meet a preset matching condition. If so, it indicates that the two refresh rates are similar or the same, and no refresh rate adjustment is needed for that display partition; therefore, the initial enable flag of the partition control module corresponding to that display partition is set to off. Otherwise, it indicates that the two refresh rates differ significantly, and refresh rate adjustment is needed for that display partition; therefore, the initial enable flag of the partition control module corresponding to that display partition is set to on. For each partition control module, which controls the display partitions in the same row, if at least one display partition in the same row has an on initial enable flag, then the final enable flag of that partition control module is on; if all display partitions in the same row have off initial enable flags, then the final enable flag of that partition control module is off.

[0107] In some embodiments of this application, the controller is specifically configured to: control the refresh rate and grayscale of multiple display partitions according to an enable flag and a first source driver flag, including: sending a corresponding enable flag to each partition control module; and for each dynamic display partition, sending the current display image corresponding to the dynamic display partition to the first source driver chip with the corresponding first source driver flag, so that the dynamic display partition displays the current display image at the current refresh rate.

[0108] In this embodiment, the current display image corresponding to the dynamically displayed partition needs to be displayed at a higher refresh rate with the original grayscale. The controller can send an enable flag to the partition control module to activate the corresponding partition control module, update the refresh rate of the display partition within the corresponding display row, and / or deactivate the corresponding partition control module to maintain the refresh rate of the display partition within the corresponding display row. For each dynamically displayed partition, the controller can determine the first source driver chip based on the first source driver flag and send the current display image without grayscale reduction processing to the first source driver chip. This achieves the display of the original current display image at a higher corresponding current refresh rate in the dynamically displayed partition.

[0109] In some embodiments of this application, the controller is further configured to: control the refresh rate and grayscale of multiple display partitions according to an enable flag and a first source driver flag; and further configured to: send an adjustment image corresponding to the static display partition to the corresponding second source driver chip for each static display partition, so that the static display partition displays the adjustment image at the current refresh rate; wherein the adjustment image is determined by grayscale reduction processing of the current display image corresponding to the static display partition.

[0110] The static display partition can be any of the multiple display partitions other than the dynamic display partition. The second source driver chip can be the source driver chip corresponding to the static display partition. It can be understood that a column can contain both dynamic and static display partitions, and one source driver chip can process the corresponding image for each display partition separately.

[0111] In this embodiment, the current display image corresponding to the static display partition needs to be displayed at a lower refresh rate by reducing the grayscale. For each static display partition, the controller can perform grayscale reduction processing on the current display image corresponding to that static display partition to obtain an adjusted image. This embodiment does not limit the specific grayscale reduction; for example, it can be reduced to a preset grayscale, which can be 0. Furthermore, the controller can determine the second source driver chip based on the second source driver identifier and send the adjusted image corresponding to the static display partition to the second source driver chip. This enables the static display partition to display the image with reduced grayscale at a lower refresh rate.

[0112] For example, such as Figure 4 As shown, if Figure 4If the previous refresh rate of the dynamic display partition does not meet the preset matching condition with the current refresh rate, then GOA3-5 needs to be activated, thus generating an enable flag for GOA3-5. If the previous refresh rate of the static display partition (excluding the dynamic display partition) meets the preset matching condition with the current refresh rate, then GOA1-2 and GOA6-N need to be disabled to prevent refresh rate updates, thus generating disable flags for GOA1-2 and GOA6-N respectively. This achieves a low refresh rate effect for the static display partition, effectively reducing panel and driver power consumption. Furthermore, the original current display image corresponding to the dynamic display partition is sent to Driver2-5. The adjusted image with lowered grayscale corresponding to the static display partition is sent to Driver1 and Driver6, achieving a low refresh rate effect for the static display partition and effectively reducing panel and driver power consumption.

[0113] Furthermore, if the refresh rate of the dynamically displayed partition needs to remain constant, the refresh rates of other statically displayed partitions need to be adjusted to 30Hz. For example, if the statically displayed partition needs to display scrolling text, it doesn't need a high refresh rate, but a lower refresh rate such as 24Hz needs to be set. Since A2-4 and F2-4 also need to have their refresh rates adjusted, the controller needs to start all partition control modules and switch the refresh rate of the statically displayed partitions to 30Hz, thus generating the corresponding enable flags for GOA1-N. This reduction in refresh rate can be achieved by increasing the vertical blanking length. Additionally, the original current display image corresponding to the dynamically displayed partition is sent to Driver2-5, and the adjusted image after grayscale reduction is sent to Driver1 and Driver6. At this point, the effect of different refresh rates for the display partitions is achieved, and the power consumption of the panel and drivers is reduced to some extent according to application requirements.

[0114] like Figure 5As shown, if a portion of the display panel displays a dynamic image while other zones display a static image, the controller can identify the display zone requiring refresh rate adjustment. After the front-end data is processed by the still frame detection module, it can output a control signal (Data_EN), a polarity value (PolVal), and the zone control module's enable flag (GOA_EN) through the hardware input / output (I / O) interface of the polarity control module in the controller. This control signal is then transmitted to the data control module (DataCtrl), which can control the output of either the original currently displayed image or an adjusted image with lowered grayscale. The data control module determines the final output image displayed on the display zone based on the image's enable flag and transmits this output image to the end-to-end control layer (P2PMAC). The polarity control module also transmits the polarity value to this end-to-end control layer. Furthermore, the zone control module's enable flag is transmitted to the image generation module, along with the field synchronization data and valid data strobe data from the front-end data.

[0115] In some embodiments of this application, the output of the controller is set based on an end-to-end protocol (P2P). The controller is further configured to: determine the first currently displayed image and the first historical displayed image of the first display partition; if the image similarity between the first currently displayed image and the first historical displayed image is greater than a second preset threshold, then the accumulated value corresponding to the first display partition is accumulated to obtain a new accumulated value; if the new accumulated value is greater than a quantity threshold, then the control word of the end-to-end protocol is adjusted to disable the function to obtain an updated control word, and the updated control word is sent to the source driver chip corresponding to the first display partition so that the source driver chip corresponding to the first display partition disables the target function corresponding to the updated control word.

[0116] In this embodiment, the first display partition can be any display partition in the static display partitions. The first currently displayed image can be the currently displayed image corresponding to the first display partition. The first historical displayed image can be the historical displayed image corresponding to the first display partition. The second preset threshold can be a pre-set threshold for image similarity. The accumulated value can be a value obtained by accumulating with 1 as the single accumulation value. The quantity threshold can be a pre-set number of times threshold. The control word can be the control word at the output end in the end-to-end protocol. The update control word can be a control word that records the disabling of the target function. The target function can be a pre-set function that triggers disabling; this embodiment does not limit the function. For example, the target function may include one or more of the following: data transmission crosstalk improvement function, brightness uniformity function, voltage balancing function, and voltage calibration function.

[0117] In this embodiment, the controller outputs based on an end-to-end protocol. During Horizontal Active (HActive) display, the controller calculates the image similarity between the first currently displayed image and the first historical displayed image of the first display partition, and determines whether the image similarity is greater than a second preset threshold. If so, the current accumulated value is accumulated using a counter to obtain a new accumulated value. A function control threshold, i.e., a quantity threshold, for the source driver chip is preset. If the new accumulated value is greater than the quantity threshold, the controller is triggered to adjust the control word of the end-to-end protocol to obtain an updated control word, which records the disabling of the target function. The controller sends the updated control word to the source driver chip corresponding to the first display partition during Horizontal Blank (HBlank) device operation, thereby disabling the target function in the source driver chip.

[0118] Thus, the control word at the controller output terminal achieves the target function of shutting down the source driver chip, further reducing the driving power consumption of the source driver chip corresponding to the static display partition, and has good effectiveness and applicability.

[0119] The display device provided in this application embodiment achieves coordinated control of refresh rate and grayscale by linking the source driver chip and the partition control module. Based on still frame detection, the partition control module and the source driver chip jointly control the display partitions. Different partition control modules are selectively switched on and off according to changes in front-end input data, enabling different display partitions to activate corresponding refresh rate, timing, and other parameters, thereby reducing the power consumption of the display panel. Furthermore, the display partitions that do not require updating refresh rate and other parameters are already determined and accurate to specific display rows. After the partition control module is turned off, the signal status is updated to the source driver chip via hardware input / output ports, causing the source driver chip to output an adjusted image with 0 or any controllable grayscale value, thereby reducing display driver power consumption.

[0120] By controlling the linkage between the controller and the source driver chip, and controlling the refresh rate through the partition control module, the display effect of various display partitions is maximized and the power consumption of display devices is reduced, thus enabling various display devices to meet different application scenarios.

[0121] To illustrate this solution in more detail, the following will use examples to illustrate it. Figures 6 to 12 To explain, it is understandable that Figures 6 to 12The steps involved may include more or fewer steps in actual implementation, and the order of these steps may also differ, as long as the partitioned display method provided in the embodiments of this application can be achieved. The executing entity of the partitioned display method can be a display device, or a functional module or functional entity within the display device that can implement the partitioned display method; no limitation is made here. Furthermore, the specific description of the partitioned display method provided in the embodiments of this application can be found in the relevant description of the above-mentioned display device, and the same or similar technical effects can be achieved; further details are omitted here.

[0122] Figure 6 A schematic flowchart of one of the partitioned display methods according to some embodiments is shown, applied to a display device, the display device including a display panel having multiple display partitions and a controller connected to the multiple display partitions, the partitioned display method may include the following steps S601 to S602.

[0123] S601. Based on the multiple current display images and multiple historical display images corresponding to the multiple display partitions, determine the first source driver identifier corresponding to the dynamic display partition among the multiple display partitions, and the enable identifier of the partition control module corresponding to the multiple display partitions.

[0124] S602. Control the refresh rate and grayscale of multiple display partitions according to the enable flag and the first source driver flag.

[0125] In some embodiments of this disclosure, multiple display partitions are arranged in a grid pattern, with display partitions in the same row corresponding to the same partition control module, and display partitions in the same column corresponding to the same source driver chip.

[0128] Step 702: In the candidate display partitions included in the dynamic display row, determine the dynamic display partition based on the current display image and the historical display image corresponding to the candidate display partition.

[0129] Step 703: Determine the source driver identifier corresponding to the dynamic display partition as the first source driver identifier.

[0130] Figure 8The third flowchart illustrates a partitioned display method according to some embodiments, such as... Figure 8 As shown, in some embodiments of this disclosure, in the multiple display rows included in the display panel, a dynamic display row is determined based on multiple currently displayed images and multiple historical display images, including:

[0131] Step 801: For each display row, determine the row image similarity based on the current display image and the historical display images corresponding to the display row.

[0132] Step 802: Among multiple display rows, the display rows whose row image similarity is less than a first preset threshold are determined as dynamic display rows.

[0133] In some embodiments of this disclosure, determining the row image similarity corresponding to a display row based on the current display image and the historical display image corresponding to the display row includes: stitching together multiple current display images of multiple display partitions within the display row to obtain a current row image, and stitching together multiple historical display images of multiple display partitions within the display row to obtain a historical row image; calculating the similarity between the current row image and the historical row image to obtain the row image similarity.

[0134] Figure 9 The fourth flowchart illustrates a partitioned display method according to some embodiments, such as... Figure 9 As shown, in some embodiments of this disclosure, the enable flag of the partition control module corresponding to the multiple display partitions is determined based on the multiple currently displayed images and multiple historical displayed images corresponding to the multiple display partitions, including:

[0135] Step 901: Determine the current refresh rate and the previous refresh rate for each display partition.

[0136] Step 902: If the previous refresh rate of the display partition and the current refresh rate meet the preset matching conditions, the initial enable flag of the display partition will be set to the off flag.

[0137] Step 903: If the previous refresh rate of the display partition does not meet the preset matching condition with the current refresh rate, the initial enable flag of the display partition will be set as the enable flag.

[0138] Step 904: For each partition control module, if the initial enable flags of the display partitions corresponding to the partition control module are all off flags, then the enable flag of the partition control module is set to off flag; otherwise, the enable flag of the partition control module is set to on flag.

[0139] In some embodiments of this disclosure, the refresh rate and grayscale of multiple display partitions are controlled according to an enable flag and a first source driver flag, including: sending a corresponding enable flag to each partition control module; and for each dynamic display partition, sending the current display image corresponding to the dynamic display partition to the first source driver chip with the corresponding first source driver flag, so that the dynamic display partition displays the current display image at the current refresh rate.

[0140] In some embodiments of this disclosure, the method further includes: sending an adjustment image corresponding to each static display partition to the corresponding second source driver chip, so that the static display partition displays the adjustment image at the current refresh rate; wherein the adjustment image is determined by performing grayscale downgrading processing on the current display image corresponding to the static display partition.

[0141] Figure 10 The fifth illustration shows a flowchart of a partitioned display method according to some embodiments, such as... Figure 10 As shown, in some embodiments of this disclosure, the controller's output is configured based on an end-to-end protocol, and the partition display method further includes:

[0142] Step 1001: Determine the first currently displayed image and the first historical displayed image of the first display partition.

[0143] Step 1002: If the image similarity between the first currently displayed image and the first historically displayed image is greater than the second preset threshold, then the accumulated value corresponding to the first display partition is accumulated to obtain a new accumulated value.

[0144] Step 1003: If the new accumulated value is greater than the quantity threshold, the control word of the end-to-end protocol is adjusted to disable the function to obtain the updated control word, and the updated control word is sent to the source driver chip corresponding to the first display partition so that the source driver chip corresponding to the first display partition disables the target function corresponding to the updated control word.

[0145] Figure 11 A schematic diagram of a partitioned display method according to some embodiments is shown, such as... Figure 11As shown, when updating the image of a display partition, the controller can obtain the current display image of the display row where the display partition is located. It determines whether the display row is a dynamic display row through still frame detection. If so, it determines whether the candidate display partitions in the dynamic display row need to call new parameters such as refresh rate and grayscale. If so, the controller sends a signal through the hardware input / output port to enable the partition control module of the candidate display partition, and the source driver chip outputs the current display image normally. If the candidate partition does not need to call new parameters, the controller sends a signal through the hardware input / output port to disable the partition control module, the source driver chip outputs an adjusted image with a fixed grayscale, and disables the target function of the source driver chip through the update control field output by the controller. Afterwards, the display image is updated in the display partition, and the system waits for the next image update. This reduces the power consumption of the display panel and the driver.

[0146] Figure 12 A schematic diagram illustrating the disabling of a target function according to some embodiments is shown, such as Figure 12 As shown, during the horizontal active period, the controller can compare the first currently displayed image and the first historically displayed image to obtain image similarity. It then determines whether the image similarity is greater than a second preset threshold. If so, the accumulated value is incremented; otherwise, it returns to compare the first currently displayed image and the first historically displayed image for the next time step. Further, it determines whether the new accumulated value is greater than a quantity threshold. If so, the controller modifies the control word during the horizontal blanking period and sends the modified control word to the corresponding source driver chip, thereby disabling the corresponding target function. If the new accumulated value is not greater than the quantity threshold, it returns to compare the first currently displayed image and the first historically displayed image for the next time step.

[0147] The partitioned display method provided in this disclosure, based on still frame detection, utilizes a controller and source driver chip partitioning linkage technology according to front-end input. This allows for selective control of the timing partitioning module, the data transmitted from the controller to the source driver chip, and the output of controllable grayscale images through the source driver chip in different screen application scenarios. This enables display partitioning at different refresh rates, reducing panel and driver power consumption. The static frame detection-based linkage between the controller, partitioning control module, and source driver chip reduces power consumption. It not only detects complex changes in both static and dynamic images, ensuring accuracy in detection, timing control, and data control, but also disables corresponding functions of the source driver chip during prolonged low-refresh-rate display partitioning, avoiding unnecessary power consumption per frame. This method can be widely applied to current diverse terminal scenarios with significant power reduction effects.

When the computer program is executed by a processor, it implements the various processes of the above-described partitioned display method and achieves the same technical effect. To avoid repetition, it will not be described again here.
