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.

[0060] 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.

[0061] In view of the above problems, the embodiments of the present disclosure provide a display control device, method and electronic device, which includes a feature detection module, a cycle inspection module, a control module, a source control component and a source driver, and can control the switches of the associated modules involved in frame data processing, storage and transmission according to the display data changes. Thus, it is possible to achieve a significant reduction in power consumption while ensuring display quality, with higher flexibility and efficiency, effectively saving development costs, and extending the use time of electronic devices.

[0062] The present disclosure provides a display control device, such as Figure 1 As shown, the device includes a feature detection module 10 , a cycle checking module 20 , a management and control module 30 , a source control component 40 and a source driver 50 .

[0063] The feature detection module 10 is used to determine a first feature value of a first frame of data to be displayed, and to determine a comparison result between the first feature value and a second feature value of a second frame of data, where the second frame of data is a previous frame of the first frame of data.

[0064] Among them, the first frame data and the second frame data may be data of images, videos, etc. that need to be displayed through the display panel, and the frame data may include pixel values, color values ​​or other parameters related to reality, which is not limited in the present disclosure. Among them, the display panel may include 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 at least one of a small pitch display panel, which is not limited in the present disclosure, 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 detection module 10 may use an algorithm to calculate the feature values ​​of the first frame data and the second frame data, and the feature values ​​may uniquely identify each frame data (including the first frame data and the second frame data). For example, the feature values ​​may be CRC (Cyclic Redundancy Check), Hash (Hash algorithm), plain code, or other encodings that may uniquely identify the frame data, and the present disclosure does not limit this.

[0066] In some embodiments, the feature detection module 10 may also store the second feature value of the second frame data, so as to facilitate comparison after determining the first feature value. In some embodiments, the feature detection module 10 may also include a storage submodule, which is used to store the second feature value, and after completing the comparison between the first feature value and the second feature value, replace the second feature value of the storage submodule with the first feature value, that is, store the first feature value as a new second feature value to replace the existing second feature value, so as to ensure that the feature value of the previous frame data is always stored in the storage submodule, so as to improve the speed and efficiency of feature value comparison.

[0067] The cycle checking module 20 is used to enable a feature continuity establishment signal if it is determined that the first frame data meets a preset data cycle arrangement rule when the comparison result is determined to be the same.

[0068] In this embodiment, the data loop arrangement rule is set according to the bit width of each pixel in the first frame data and the data stream of the display panel (Panel) displaying the first frame data. In some embodiments, the data loop arrangement rule can be represented by nP (that is, represented by n×P), where n refers to the bit width of the pixel data, and p refers to the data stream of the display panel. For example, assume that the resolution of a display panel is 1920×1080, that is, there are 1920 columns and 1080 rows of pixels. If each pixel uses 24 bits to represent the color, then the amount of data for each frame of data is 1920×1080×24 bits. In this case, p=1920×1080, and n can take any integer value from 1 to 24 according to actual needs (that is, n∈[1,24]).

[0069] The control module 30 is used to stop the clock and / or power supply of the associated module in response to the enabled feature continuous establishment signal. In this way, when it is determined that the content displayed on the current display panel has not changed and the current content can continue to be displayed without updating the frame data, the feature continuous establishment signal can be enabled, and then some front-end associated modules that are not involved in the work in this case can be turned off to reduce power consumption.

[0070] Wherein, the association module includes modules involved in the process of processing, storing and transmitting the first frame data to the source control component. In some embodiments, the association module can be IPs (Intellectual Property Cores, which can be pre-designed, reusable hardware design components, processor cores, communication interfaces or other functional modules), SRAM (Static Random Access Memory) for frame data storage and other memories and storage controllers (RAMcontrol), DSC modules (which are used to compress frame data according to display stream compression technology (Display Stream Compression)), clock controllers (Reset Clock Control, RCC), power management units (Power Management Unit, PMU), etc., and the present disclosure does not limit this.

[0071] In some embodiments, the cycle checking module 20 is further configured to turn off the characteristic continuous establishment signal when determining that the comparison result is not the same. The control module 30 is further configured to maintain the clock and power supply of the association module in response to the turned-off characteristic continuous establishment signal.

[0072] The source control component 40 is responsible for managing the source and direction of the data flow. It ensures that the data is processed in the correct order and time, and coordinates the data transmission between different modules. The source control component 40 can be used to respond to the enabled feature continuity establishment signal and send the target frame data that conforms to the data cycle arrangement rule to the source driver 50. The source control component 30 is also used to respond to the turned-off feature continuity establishment signal and send the acquired next frame data to be displayed as the target frame data to the source driver 50. Among them, in response to the turned-off feature continuity establishment signal, the source control component 30 can send the next frame data to be displayed stored in a memory such as a static random access memory SRAM as the target frame data to the source driver 50.

[0073] In some embodiments, the cycle checking module 20 is further used to store frame data that conforms to the data cycle arrangement rule, and these frame data may be first frame data, second frame data, or other frame data that conforms to the data cycle arrangement rule. In this way, the source control component 40 can obtain frame data that conforms to the data cycle arrangement rule from the cycle checking module 20 as target frame data.

[0074] In some embodiments, the source control component 40 sends the frame data that conforms to the data cycle arrangement rule as the target frame data to the source driver in any of the following ways:

[0075] Sending the frame data conforming to the data cycle arrangement rule as target frame data to the source driver 50 through a built-in self test (BIST);

[0076] Using an nP loop pattern generator (nP Loop Pattern Generator) to send the frame data that complies with the data loop arrangement rule as target frame data to the source driver 50;

[0077] The storage controller is used to send the frame data that complies with the data cycle arrangement rule as the target frame data to the source driver 50 .

[0078] The source driver 50 is used to drive the display panel to display content according to the target frame data. The source driver 50 can convert digital signals into analog signals according to the target frame data to drive components of the display panel to display content.

[0079] In this embodiment, the display control device can be applied to a display device, and the display device can include multiple display units and at least one display control device. The display unit includes the display panel. Furthermore, the display device can be applied to an electronic device.

[0080] In this embodiment, the electronic device may further include a data processing module, IPs, and a storage controller. The data processing module may be a processor for performing data processing to form frame data, etc., which is not limited in the present disclosure. The storage controller is used to store the frame data from the IPs in a memory such as an SRAM under the control of the IPs.

[0081] In this embodiment, IPs and feature detection module 10 can respectively obtain frame data from the data processing module through corresponding interfaces (Interface, IF). Among them, feature detection module 10 can obtain frame data from the data processing module through corresponding interface IF and use it as the first frame data and then determine the first feature value. After IPs obtains the frame data, it stores these frame data in a memory such as SRAM through a storage controller. In this way, source control component 40 can obtain frame data stored in a memory such as SRAM through a storage controller, and can also obtain frame data stored in the feature detection module 10 that conforms to the data cycle arrangement rule, and then can select the frame data stored in the feature detection module 10 that conforms to the data cycle arrangement rule or the frame data stored in a memory such as SRAM as the target frame data to be sent to the source driver based on whether the feature continuous establishment signal is enabled.

[0082] The following combination Figure 2-Figure 4 The working principle and process of the display control device provided by the embodiment of the present disclosure are schematically described. Figure 3 The figure shows the data transmission process in which the display content in the display panel changes and the frame data to be displayed needs to be continuously acquired to realize the content display. Figure 4 The data transmission process shown is to realize content display without changing the display content in the display panel and without continuously acquiring the frame data to be displayed.

[0083] like Figure 2 As shown, in step S101, after the frame data is formed in the data processing module, the frame data can be cached in a MIPI FIFO manner (First In, First Out). MIPI FIFO refers to the FIFO buffer used in the MIPI (Mobile Industry Processor Interface) interface IF to store frame data. Then, as Figure 3-Figure 4 As shown, IPs and feature detection module 10 can respectively obtain the previous frame data A in the queue from the FIFO buffer through the corresponding interface IF. Then, IPs controls the storage controller to store the frame data A in a memory such as SRAM.

[0084] like Figure 2 As shown, in step S102, the feature detection module uses the frame data A as the first frame data to determine the corresponding first feature value, and then compares it with the second feature value of the stored second frame data to obtain a comparison result, and Figure 3-Figure 4 The comparison result is sent to the loop check module as shown. Figure 3-Figure 4As shown, the loop checking module further determines whether the comparison result is the same, and if so, executes step S103. If the comparison result is different, the IPs and feature detection module 10 in step S101 respectively obtain the next frame data of the queue from the FIFO buffer through the corresponding interface IF.

[0085] like Figure 2 As shown, in step S103, the cyclic checking module obtains the first frame of data to achieve data synchronization.

[0086] like Figure 2 As shown, in step S104, if the cycle checking module determines that the comparison result is the same, it further determines whether the first frame data meets the preset data cycle arrangement rule. If the first frame data meets the preset data cycle arrangement rule, the feature continuous establishment signal is enabled and step S105 is executed. If the first frame data does not meet the preset data cycle arrangement rule, the feature continuous establishment signal is turned off, and then as shown in FIG. Figure 3 The source driver component shown will respond to the shutdown characteristic continuous establishment signal, obtain frame data A through the storage controller, and send frame data A as the target frame number to the source driver. The source driver drives the display panel to display content according to the target frame data (ie, frame data A).

[0087] like Figure 2 , Figure 4 As shown, in step S105, the cycle checking module stores the frame data that most recently complies with the data cycle arrangement rule.

[0088] like Figure 2 , Figure 4 As shown, in step S106, the management and control module stops the clock and / or power supply of the associated modules such as IPs, storage controller, SRAM, etc. in response to the enabled feature continuous establishment signal to reduce power consumption.

[0089] like Figure 2 , Figure 4 As shown, in step S107, the source control component is used to respond to the enabled characteristic continuous establishment signal to send the frame data that conforms to the data cycle arrangement rule as the target frame data to the source driver, and the source driver drives the display panel to display the content according to the target frame data (that is, the frame data that conforms to the data cycle arrangement rule).

[0090] 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.

[0091] Wherein, the display unit includes the above-mentioned display panel.

[0092] An embodiment of the present disclosure further provides an electronic device, comprising the above-mentioned display device.

[0093] The embodiment of the present disclosure further provides a chip, wherein the chip includes the above-mentioned display control device.

[0094] The present disclosure also provides a display control method, the method comprising:

[0095] Determine a first characteristic value of a first frame of data to be displayed, and determine a comparison result of the first characteristic value and a second characteristic value of a second frame of data, where the second frame of data is a previous frame of the first frame of data;

[0096] In the case where the comparison result is determined to be the same, if it is determined that the first frame data meets the preset data cycle arrangement rule, a feature continuous establishment signal is enabled;

[0097] In response to the enabled characteristic continuous establishment signal, stopping the supply of clock and / or power to the associated module;

[0098] In response to the enabled characteristic continuous establishment signal, the frame data conforming to the data cycle arrangement rule is sent as the target frame data to the source driver, so that the source driver drives the display panel to display the content according to the target frame data;

[0099] The association module includes modules involved in the process of processing and storing the first frame data and transmitting the first frame data to the source control component.

[0100] It should be noted that although the above embodiments are used as examples to introduce the display control device, method and electronic device, those skilled in the art will understand that the present disclosure should not be limited thereto. In fact, the user can flexibly set each step and module according to personal preferences and / or actual application scenarios, as long as it complies with the technical solution of the present disclosure.

The specific implementation can refer to the description of the above method embodiments, and for the sake of brevity, it will not be repeated here.

The computer-readable storage medium can be a volatile or non-volatile computer-readable storage medium.
