Description

Technical Field

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

[0002] With the continuous advancement of smart device technology, display technology is developing in a more efficient and energy-saving direction. In the related technology, there are some solutions to reduce the power consumption of the device. For example, when the user has not operated for a period of time, the display screen can automatically reduce the refresh rate or brightness, but the refresh rate and brightness adjustment of the entire display screen are still too simple, and it is actually judging whether the user continues to watch the display screen, and reducing the refresh rate or brightness when it is determined that the user may not continue to watch. The components of the display screen are updated and adjusted, and components such as lamp beads with lower power consumption are used. However, this requires updating the performance of the display screen itself. The degree of power consumption reduction depends on the device itself, and in fact, there is no consideration of how to reduce the power consumption of the device while maintaining the display quality during the display process. Therefore, how to propose a display control scheme that reduces the power consumption of the device while maintaining the display quality is a technical problem that needs to be solved urgently in this technical field.

[0057] With the continuous advancement of smart device technology, display technology is developing towards a more efficient and energy-saving direction. How to propose a display control solution that reduces device power consumption while maintaining display quality is a technical problem that needs to be solved urgently in this technical field.

[0058] In view of the above problems, the embodiments of the present disclosure provide a display control device, method and electronic device, which includes a data detection module, a feature value comparison module, an area marking module and a display control module, and can divide the screen into a refresh area and a non-refresh area according to the change of display data, and make each screen sub-area have a matching refresh frequency and frame rate in a multi-frequency display control mode. Thus, it is possible to achieve a significant reduction in power consumption while ensuring display quality, with higher flexibility and efficiency, effectively save development costs, and extend the use time of electronic devices.

[0059] Figure 1 FIG. 1 is a block diagram of a display control device 100 according to an embodiment of the present disclosure. 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 screen sub-region in the display panel, and determine the characteristic value of the display data corresponding to each screen sub-region.

[0061] Wherein, the data detection module 110 can store the display data of each screen sub-area in the display panel, and the display data may include pixel values, color values ​​or other display-related parameters, which are not limited in the present disclosure. Wherein, the screen sub-area is composed of a certain number of continuous pixel rows, and the pixel row is the smallest unit row constituting the image, and each row contains a certain number of pixel points. The number of pixel rows included in the screen sub-area can be set and adjusted according to actual needs, which is not limited in the present disclosure. Wherein, the data detection module 110 can use an algorithm to calculate the characteristic value of the display data corresponding to each of the screen sub-areas, and the characteristic value can uniquely identify the display data of each screen sub-area. For example, the characteristic value can be a CRC (Cyclic Redundancy Check), Hash (Hashalgorithm, Hash algorithm), a clear code, etc., which can identify the uniqueness of the display data of the screen sub-area, which is not limited in the present disclosure.

[0062] In this embodiment, the screen sub-area division of the display panel can be predetermined by the data detection module or the host of the electronic device where the device is located according to the content display of the display panel. The screen sub-area division can be performed in combination with information such as the type of content currently displayed on the display panel and whether it is displayed in full screen, and the present disclosure does not limit this.

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

[0064] The display panel may include at least one of a liquid crystal display panel, a micro-LED display panel, a light-emitting diode display panel, a mini light-emitting diode display panel, a quantum dot light-emitting diode display panel, an organic light-emitting diode display panel, a cathode ray tube display panel, a digital light processing display panel, a field emission display panel, a plasma display panel, an electrophoretic display panel, an electrowetting display panel, and a small pitch display panel. The present disclosure does not limit this, and relevant technicians can select 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 of the feature value of the current frame display data and the feature value corresponding to the previous frame display data in each of the picture sub-areas.

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

[0067] The area marking module 130 is used to determine the area type of each of the screen sub-areas according to the comparison results corresponding to each of the screen sub-areas, and the area type includes a non-refresh area and a refresh area.

[0068] Among them, the area marking module 130 can be used to divide the types of screen sub-areas according to the comparison results corresponding to the screen sub-areas. The area types include non-refresh areas and refresh areas. The non-refresh area refers to an area where the display data has not changed or has changed very little in multiple consecutive frames of the screen, for example, 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, etc., although the content has changed, the change speed is slow. The refresh area refers to an area where the display data changes and needs to be updated in real time or at a high frequency. The refresh area usually contains dynamic pictures, such as video playback areas, game pictures, etc., so it is necessary to maintain a high refresh frequency to ensure smooth pictures. The present disclosure does not limit this. For a certain screen sub-area, if the characteristic value of the display data of the previous frame is the same as or very close to the characteristic value of the display data of the current frame, it can be considered that the display data of the screen sub-area has not changed or has changed very little, and the refresh frequency requirement is low, and it can be determined as a non-refresh area. If the feature value of the previous frame display data is different from or greatly different from the feature value of the current frame display data, it can be considered that the display data of the sub-area of ​​the screen has changed, and the refresh rate requirement is high, and it can be determined as a refresh area. The degree of similarity between the feature values ​​to determine the non-refresh area can be set as needed.

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

[0070] Among them, the refresh frequency refers to the speed at which the picture data on the display panel is updated. In a possible implementation method, a refresh frequency range can be set, and the refresh frequency in different ranges can be defined as different refresh rates. For example, the refresh frequency in the range of 0Hz-60Hz is defined as a low-frequency refresh rate, the refresh frequency in the range of 60Hz-90Hz is defined as a medium-frequency refresh rate, and the refresh frequency in the range of 90Hz-120Hz is defined as a medium-frequency refresh rate. The refresh frequencies corresponding to picture sub-areas of different area types are different, and the present disclosure does not impose any restrictions on this.

[0071] The frame rate refers to the number of frames displayed per second. The frame rate and the refresh rate are generally matched. The higher the refresh rate, the higher the corresponding frame rate. The frame rate corresponding to different refresh rates can be set according to actual needs, and the present disclosure does not limit this.

[0072] In this embodiment, in the multi-frequency display control mode, the refresh frequency and frame rate of different areas on the display panel can be dynamically adjusted according to the change of the displayed content, so as to save power consumption while ensuring the display effect. In a possible implementation, the multi-frequency display control mode can be entered when 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 display control device 100 of the embodiment of the present application, different screen sub-areas of the display panel can be divided into refresh areas and non-refresh areas according to changes in display data. In the multi-frequency display control mode, each screen sub-area 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 slightly, thereby achieving a significant reduction in power consumption while ensuring display quality, having both higher flexibility and efficiency, effectively saving development costs, and being able to extend the service life of the electronic device.

[0074] In one possible implementation, the display control module 140 can be used to determine to enter the full-frame screen refresh mode (for example, switching from the above-mentioned multi-frequency display control mode to the full-frame screen refresh mode) when a touch operation on the display panel is detected, and adjust the refresh frequency of each of the screen sub-areas to the target frequency, and the frame rate to the target frame rate, so as to ensure the screen display effect and response speed under the touch operation. The target frequency is greater than the refresh frequency of the screen sub-area in the non-refresh area (for example, greater than the first frequency described below), and the target frame rate is greater than the frame rate of the screen sub-area in the non-refresh area (for example, greater than the first frame rate described below). The target frequency and the target frame rate may be the same as the refresh frequency and the frame rate of the refresh area, or they may be different.

[0075] According to the display control device of the embodiment of the present disclosure, through the coordinated work of the data detection module, the feature value comparison module, the area marking module and the display control module, the area type of each screen sub-area in the display panel can be accurately distinguished. In the multi-frequency display control mode, each of the screen sub-areas has a matching refresh frequency and frame rate, thereby achieving the goal of reducing device power consumption while maintaining display quality, and when a touch operation on the display panel is detected, it is switched back to the full-frame screen refresh mode in time to ensure that the screen triggered by the touch operation is displayed with high quality, thereby ensuring the display effect and user viewing experience.

[0076] Figure 2 FIG. 1 is a block diagram of a data detection module 110 according to an embodiment of the present disclosure. Figure 2As shown, in a possible implementation, the data detection module 110 includes a storage submodule 111, and the storage submodule 111 is used to store display data corresponding to each screen sub-area. 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 memory, flash memory, magnetic disk or optical disk, and the present disclosure does not limit this.

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

[0078] A screen sub-region belonging to a non-refresh area in the screen sub-region is determined as a first screen sub-region, and a refresh frequency of the first screen sub-region is controlled to be a first frequency matching the screen display characteristics, and display data of the first screen sub-region stored in the storage submodule 111 is controlled to be sent to the display panel at a first frame rate.

[0079] A screen sub-region belonging to the refresh zone in the screen sub-region is determined as a second screen sub-region, and a refresh frequency of the second screen sub-region is controlled to be a second frequency matching the screen display characteristics, and display data of the second screen sub-region stored in the storage submodule 111 is controlled to be sent to the display panel at a second frame rate.

[0080] 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-area may include one or more. When the first screen sub-area includes multiple, the first frequencies (refresh frequencies) corresponding to different first screen sub-areas may be the same or different, and the first frequencies (refresh frequencies) corresponding to different first screen sub-areas may be set according to the screen display characteristics of the first screen sub-area.

[0082] The picture display feature refers to various characteristics that can determine or affect the picture quality on the display panel, including but not limited to the display brightness, contrast, color saturation, clarity, etc. of the picture, and the present disclosure does not limit this. For example, the display brightness is set as the picture display feature, and the display brightness in different brightness ranges corresponds to different refresh frequencies, and the brightness range includes at least a first brightness range and a second brightness range with successively increasing brightness, and the refresh frequency corresponding to the first brightness range is less than the refresh frequency corresponding to the second brightness range, and as the brightness increases successively, the refresh frequency corresponding to the brightness range with higher brightness is also higher.

[0083] The first frequency matches the display characteristics of the picture, and the first frame rate matches the first frequency. The second frequency matches the display characteristics of the picture, and the second frame rate matches the second frequency, so as to ensure the smoothness and synchronization of the displayed picture.

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

[0085] In this implementation, since the display data in the screen sub-area belonging to the display area needs to be continuously updated in real time, in some embodiments, the display control module can also directly send a data sending signal to the host, so that the host can continuously send the display data corresponding to the screen sub-area of ​​the display area to the display panel in response to the data sending signal, and control the storage submodule to no longer send the display data corresponding to the screen sub-area of ​​the display area to the display panel. Among them, the display control module can also send a data stop sending signal to the host, so that the host can stop sending the display data corresponding to the screen sub-area of ​​the non-display area to the display panel in response to the data stop sending signal. And the host can also respond to the data stop sending signal by turning off the high impedance state (High Impedance State) of the source driver (Source Driver), turning off the mask or shielding signal of the gate clock (Gate Clock), turning off the multiplexing (Multiplexing) function, etc. to shut down the data transmission channel from the host to the screen sub-area of ​​the non-display area in the display panel.

[0086] For example, in a certain example, when a user is watching a video on a display panel, the working principle and process of the display control device may be as follows: when the screen (i.e., the display panel) of the mobile phone is displaying content, if no touch operation is detected within a predetermined time period, the multi-frequency display control mode may be controlled, and the display panel may be further divided into regions based on the content display of the display panel. If the regions are divided into Figure 3The three screen sub-areas shown. Then, based on the comparison result of the characteristic values ​​of the display data, it is determined that the three screen sub-areas are non-display area, display area and non-display area from top to bottom. Then, based on the screen display characteristics, the refresh frequency and frame rate of each screen sub-area are further determined. For example, the refresh frequencies of the non-display area, display area and non-display area of ​​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 controlled to be sent to the display panel at the corresponding frame rate, and the display data of the display area stored in the storage submodule is controlled to be sent to the display panel at the corresponding frame rate; so that the display panel displays content based on the received display data.

[0087] The embodiment of the present disclosure further provides a display device, comprising a plurality of display units and at least one of the above-mentioned display control devices.

[0088] Wherein, the display unit includes the above-mentioned display panel.

[0094] Determining the area type of each of the screen sub-areas according to the comparison results corresponding to each of the screen sub-areas, wherein the area type includes a non-refresh area and a refresh area;

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

[0096] The refresh frequency of the screen sub-region in the refresh area is greater than the refresh frequency of the screen sub-region in the non-refresh area.
