Description

Technical Field

[0001] This disclosure relates to the field of display control technology, and in particular to a display control device, method and electronic device. Background Technology

[0002] With the continuous advancement of smart device technology, display technology is developing towards greater efficiency and energy saving. Among related technologies, some solutions exist to reduce device power consumption. For example, when a user is inactive for a period of time, the display can automatically reduce its refresh rate or brightness. However, the overall refresh rate and brightness adjustment of the display is still too simplistic, and in reality, it only reduces the refresh rate or brightness when it determines that the user may no longer be watching the display. Updating and adjusting the display components, using lower-power LEDs and other devices, requires upgrading the display's performance itself. The degree of power reduction depends on the components themselves, and it doesn't actually consider how to reduce device power consumption while maintaining display quality. Therefore, how to propose a display control scheme that reduces device power consumption while maintaining display quality is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0056] Furthermore, to better illustrate this disclosure, numerous specific details are set forth in the following detailed description. Those skilled in the art will understand that this disclosure can be practiced without certain specific details. In some instances, methods, means, components, and circuits well known to those skilled in the art have not been described in detail in order to highlight the main points of this disclosure.

[0057] With the continuous advancement of smart device technology, display technology is developing towards greater efficiency and energy saving. How to propose a display control scheme that reduces device power consumption while maintaining display quality is a pressing technical problem to be solved in this field.

[0058] To address the aforementioned issues, this disclosure provides a display control device, method, and electronic device. The device includes a data detection module, a feature value comparison module, a region marking module, and a display control module. It can divide the screen into refresh and non-refresh areas based on changes in display data. In a multi-frequency display control mode, it ensures that each sub-region of the screen has a matching refresh rate and frame rate. This achieves a significant reduction in power consumption while maintaining display quality, offering greater flexibility and efficiency, effectively saving development costs, and extending the lifespan of the electronic device.

[0059] Figure 1 A block diagram of a display control device 100 according to an embodiment of the present disclosure is shown. Figure 1 As shown, the device includes: a data detection module 110, a feature value comparison module 120, a region marking module 130, and a display control module 140.

[0060] The data detection module 110 is used to store the display data corresponding to each sub-region of the display panel, and to determine the feature value of the display data corresponding to each sub-region of the display panel.

[0061] The data detection module 110 can store display data for each sub-region of the display panel. This display data may include pixel values, color values, or other display-related parameters, which are not limited in this disclosure. Each sub-region is composed of a certain number of consecutive pixel rows, which are the smallest unit constituting an image. Each row contains a certain number of pixels. The number of pixel rows in each sub-region can be set and adjusted according to actual needs, which is not limited in this disclosure. The data detection module 110 can use an algorithm to calculate the feature value of the display data corresponding to each sub-region. This feature value can uniquely identify the display data of each sub-region. For example, the feature value can be a unique encoding such as CRC (Cyclic Redundancy Check), Hash (Hashalgorithm), or plaintext, which can identify the uniqueness of the display data of the sub-region. This disclosure is not limited in this regard.

[0062] In this embodiment, the sub-region division of the display panel can be predetermined by the data detection module or the host of the electronic device based on the content displayed on the display panel. The sub-region division can be based on information such as the type of content currently displayed on the display panel and whether it is displayed in full screen; this disclosure does not impose any limitations on this.

[0063] In this embodiment, the data detection module can first obtain the display data that needs to be displayed on the display panel from the host, and then determine the feature value.

[0064] The display panel may include at least one of the following: liquid crystal display panel, micro light-emitting diode display panel, light-emitting diode display panel, mini light-emitting diode display panel, quantum dot light-emitting diode display panel, organic light-emitting diode display panel, cathode ray tube display panel, digital light processing display panel, field emission display panel, plasma display panel, electrophoretic display panel, electrowetting display panel, and small-pitch display panel. This disclosure does not limit the selection of this type of panel, and those skilled in the art can choose an appropriate display panel according to actual needs. In one example, the display panel may be a TDDI (Touch and Display Driver Integration) display panel.

[0065] The feature value comparison module 120 is used to determine the comparison result between the feature value of the current frame display data and the feature value corresponding to the previous frame display data in each of the sub-regions of the screen.

[0066] The feature value comparison result refers to the result of comparing the feature values ​​of each sub-region of the current frame with those of the previous frame to determine whether they are consistent or different. The feature values ​​of sub-regions at the same position in the current and previous frames can be compared one by one. For example, CRC can be used to calculate the feature value of the display data of each sub-region, obtaining the corresponding CRC check value. By comparing the CRC check values ​​of the display data of the sub-regions at the same position in the current and previous frames, it can be determined whether the content of that region has changed. If the CRC check value of a sub-region in the previous frame is A, and the CRC check value in the current frame is also A, then the feature value comparison result is consistent. If the CRC check value of the current frame is B (B≠A), then the feature value comparison result is inconsistent. The data detection module 110 or the feature value comparison module 120 can store the feature values ​​of the previous frame display data of each sub-region for comparison with the feature values ​​of the current frame display data of each sub-region.

[0067] The region marking module 130 is used to determine the region type of each of the sub-regions of the screen based on the comparison results corresponding to each of the sub-regions of the screen. The region type includes non-refreshing areas and refreshing areas.

[0068] The region marking module 130 can be used to classify the types of sub-regions of the screen based on the comparison results corresponding to the sub-regions. Region types include non-refreshing regions and refreshing regions. Non-refreshing regions refer to areas where the displayed data does not change or changes very little in multiple consecutive frames. Examples include background images, fixed UI (User Interface) elements, etc., whose content remains unchanged for a long time, and some slowly changing dynamic elements, such as gradient animations, where the content changes, but the rate of change is slow. Refreshing regions, on the other hand, refer to areas where the displayed data changes and requires real-time or high-frequency updates. Refreshing regions typically include dynamic scenes, such as video playback areas and game scenes, thus requiring a high refresh rate to ensure smooth playback. This disclosure does not impose any limitations on this. For a given sub-region, if the feature value of the displayed data in the previous frame is the same as or very similar to the feature value of the displayed data in the current frame, then the displayed data in that sub-region can be considered unchanged or changes very little, with low refresh rate requirements, and can be identified as a non-refreshing region. If the feature values ​​of the data displayed in the previous frame are different from or significantly different from the feature values ​​of the data displayed in the current frame, then the data displayed in that sub-region of the screen can be considered to have changed, requiring a high refresh rate, and can be identified as a refresh zone. The degree to which the feature values ​​are similar enough to define a non-refresh zone can be set as needed.

[0069] The display control module 140 is used to control the refresh rate and frame rate of each sub-region of the screen according to the region type of each sub-region of the screen in the multi-frequency display control mode, so that each sub-region of the screen has a matching refresh rate and frame rate; wherein, the refresh rate of the sub-region of the refresh area is greater than the refresh rate of the sub-region of the non-refresh area.

[0070] The refresh rate refers to how fast the image data on the display panel is updated. In one possible implementation, a refresh rate range can be set, and different refresh rates can be defined in different ranges. For example, the refresh rate in the range of 0Hz-60Hz can be defined as the low refresh rate, the refresh rate in the range of 60Hz-90Hz can be defined as the medium refresh rate, and the refresh rate in the range of 90Hz-120Hz can be defined as the medium refresh rate. The refresh rate corresponding to different sub-regions of the image is different for different area types, and this disclosure does not limit this.

[0071] Frame rate refers to the number of frames displayed per second. Frame rate and refresh rate are generally correlated; a higher refresh rate corresponds to a higher frame rate. The frame rate corresponding to different refresh rates can be set according to actual needs, and this disclosure does not impose any restrictions on this.

[0072] In this embodiment, under the multi-frequency display control mode, the refresh rate and frame rate of different areas on the display panel can be dynamically adjusted according to changes in the displayed content, thereby saving power while ensuring display quality. In one possible implementation, the multi-frequency display control mode can be entered if no touch operation is detected within a predetermined time period. The length of the preset time period can be set as needed.

[0073] According to the embodiments of this application, the display control device 100 can divide different sub-regions of the display panel into refresh areas and non-refresh areas based on changes in display data. In the multi-frequency display control mode, each sub-region of the display panel has a matching refresh frequency and frame rate, so that the refresh frequency of the refresh area where the display data changes is greater than the refresh frequency of the non-refresh area, and a lower refresh frequency is set for the non-refresh area where the display data does not change or changes only slightly. This can achieve a significant reduction in power consumption while ensuring display quality, and also has higher flexibility and efficiency, effectively saves development costs, and can extend the service life of electronic devices.

[0074] In one possible implementation, the display control module 140 can be used to determine, upon detecting a touch operation on the display panel, to enter a full-frame refresh mode (e.g., switching from the aforementioned multi-frequency display control mode to a full-frame refresh mode), and adjust the refresh frequency and frame rate of each sub-region of the screen to the target frequency and frame rate, respectively, to ensure the display effect and response speed under touch operation. The target frequency is greater than the refresh frequency of the non-refreshing sub-region of the screen (e.g., greater than the first frequency mentioned below), and the target frame rate is greater than the frame rate of the non-refreshing sub-region of the screen (e.g., greater than the first frame rate mentioned below). The target frequency and target frame rate can be the same as or different from the refresh frequency and frame rate of the refresh area.

[0075] According to the display control device of this disclosure, through the coordinated work of the data detection module, the feature value comparison module, the area marking module and the display control module, it can accurately distinguish the area type of each sub-area of ​​the screen in the display panel. In the multi-frequency display control mode, each sub-area of ​​the screen has a matching refresh rate and frame rate, thereby reducing device power consumption while maintaining display quality. When a touch operation on the display panel is detected, it switches back to the full-frame refresh mode in a timely manner to ensure that the screen triggered after the touch operation is displayed with high quality, thus ensuring display effect and user viewing experience.

[0076] Figure 2 A block diagram of a data detection module 110 according to an embodiment of the present disclosure is shown. Figure 2As shown, in one possible implementation, the data detection module 110 includes a storage submodule 111, which stores display data corresponding to each sub-region of the screen. The storage submodule 111 can be implemented by any type of volatile or non-volatile storage device or a combination thereof, such as static random access memory (SRAM), electrically erasable programmable read-only memory (EEPROM), erasable programmable read-only memory (EPROM), programmable read-only memory (PROM), read-only memory (ROM), magnetic storage, flash memory, magnetic disk, or optical disk; this disclosure does not limit this.

[0077] In one possible implementation, under multi-frequency display control mode, controlling the refresh rate and frame rate of each sub-region of the screen according to its region type may include:

[0078] The sub-region of the screen that belongs to the non-refresh area is identified as the first sub-region of the screen, and the refresh rate of the first sub-region of the screen is controlled to a first frequency that matches the screen display characteristics. The display data of the first sub-region of the screen stored in the storage sub-module 111 is sent to the display panel at the first frame rate.

[0079] The sub-region of the screen that belongs to the refresh area is identified as the second sub-region of the screen, and the refresh frequency of the second sub-region of the screen is controlled to a second frequency that matches the screen display characteristics. The display data of the second sub-region of the screen stored in the storage sub-module 111 is sent to the display panel at the second frame rate.

[0080] Wherein, the first frequency is less than the second frequency, and the first frequency is greater than or equal to 0.

[0081] In this implementation, the first screen sub-region may include one or more. When there are multiple first screen sub-regions, the first frequency (refresh rate) corresponding to different first screen sub-regions may be the same or different. The first frequency (refresh rate) corresponding to different first screen sub-regions may be set according to the screen display characteristics of the first screen sub-region.

[0082] The display characteristics refer to various features that determine or affect the image quality on the display panel, including but not limited to display brightness, contrast, color saturation, and sharpness. This disclosure does not limit these features. For example, display brightness can be set as a display characteristic. Different refresh rates correspond to different brightness ranges. The brightness range includes at least a first brightness range and a second brightness range where brightness increases sequentially. The refresh rate corresponding to the first brightness range is lower than that corresponding to the second brightness range, and as the brightness increases sequentially, the higher the brightness range, the higher the refresh rate.

[0083] The first frequency is matched to the display characteristics of the image, and the first frame rate is also matched to the first frequency. The second frequency is matched to the display characteristics of the image, and the second frame rate is also matched to the second frequency, to ensure the smoothness and synchronization of the displayed image.

[0084] The correspondence between the first frequency, the first frame rate, the second frequency, the second frame rate, the display characteristics, and the area type of the sub-regions of the screen can be preset as needed.

[0085] In this implementation, since the display data in the sub-regions of the display area needs to be continuously updated in real time, in some embodiments, the display control module can also directly send a data transmission signal to the host, so that the host can continuously send the display data corresponding to the sub-regions of the display area to the display panel in response to the data transmission signal, and control the storage sub-module to stop sending the display data corresponding to the sub-regions of the display area to the display panel. The display control module can also send a data stop transmission signal to the host, so that the host can stop sending the display data corresponding to the sub-regions of the non-display area to the display panel in response to the data stop transmission signal. Furthermore, the host can also shut down the data transmission channel to the sub-regions of the non-display area in the display panel in response to the data stop transmission signal by disabling the high impedance state of the source driver, disabling the mask or shield signal of the gate clock, and disabling the multiplexing function.

[0086] For example, in a scenario where a user is watching a video using the display panel, the working principle and process of the aforementioned display control device can be as follows: During the display of content on the phone's screen (i.e., the display panel), if no touch operation is detected within a predetermined time period, a multi-frequency display control mode can be implemented. Furthermore, based on the content displayed on the display panel, the display panel can be divided into areas. For example, if the division includes areas such as... Figure 3The diagram shows three sub-regions of the screen. Then, based on the comparison results of the feature values ​​of the display data, the three sub-regions are determined from top to bottom to be a non-display area, a display area, and a non-display area. Next, based on the screen display characteristics, the refresh rate and frame rate of each sub-region are determined. For example, the refresh rates of the non-display area, display area, and non-display area on the display panel from top to bottom are medium frequency, high frequency, and low frequency, respectively. Then, the display data of the non-display area stored in the storage submodule is sent to the display panel according to the corresponding frame rate, and the display data of the display area stored in the storage submodule is also sent to the display panel according to the corresponding frame rate; so that the display panel displays content based on the received display data.

[0087] This disclosure also provides a display device, including a plurality of display units and at least one of the above-described display control devices.

[0088] The display unit includes the aforementioned display panel.

[0094] Based on the comparison results corresponding to each of the aforementioned sub-regions of the screen, the region type of each of the aforementioned sub-regions of the screen is determined, and the region type includes non-refreshing area and refreshing area;

[0095] In the multi-frequency display control mode, the refresh frequency and frame rate of each sub-region are controlled according to the region type of each sub-region, so that each sub-region has a matching refresh frequency and frame rate.

[0096] The refresh rate of the sub-regions in the refresh zone is greater than that of the sub-regions in the non-refresh zone.
