Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of display control, and in particular, to a display control apparatus, method and electronic device. BACKGROUND

[0002] With the continuous progress of intelligent device technology, display technology is developing towards higher efficiency and energy saving. In the related art, there are some solutions to reduce the power consumption of devices, for example, when a user has not operated for a period of time, the display screen can automatically reduce the refresh rate or brightness. However, the adjustment of the refresh rate and brightness of the entire display screen is still too simple, and in fact, it is to determine whether the user continues to watch the display screen and to reduce the refresh rate or brightness in the case where it is determined that the user may no longer continue to watch. The device of the display screen is updated and adjusted, and a lamp bead with lower power consumption is used. However, this requires updating the performance of the display screen itself, and the degree of power consumption reduction depends on the device itself, and in fact, it does not consider 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 solution for reducing the power consumption of the device while maintaining the display quality is a technical problem to be solved in the technical field.

[0060] With the continuous progress of intelligent device technology, display technology is developing towards higher efficiency and energy saving. How to propose a display control scheme that reduces device power consumption while maintaining display quality is a technical problem that needs to be solved in the technical field.

[0061] To solve the above problems, the present disclosure provides a display control device, method and electronic device. The device includes a feature detection module, a cycle checking module, a control module, a source control component and a source driver. The switches of the associated modules involved in the processing, storage and transmission of frame data can be controlled according to the changes in display data. Thus, the power consumption can be greatly reduced while ensuring the display quality, with higher flexibility and efficiency, effectively saving development costs, and prolonging the use time of the electronic device.

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

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

[0064] The first frame data and the second frame data can be data of images, videos and the like that need to be displayed through a display panel. The frame data can include pixel values, color values or other parameters related to reality, and the present disclosure does not limit this. The display panel can include at least one of a liquid crystal display panel, a micro light emitting diode 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, and the present disclosure does not limit this. The skilled person can select an appropriate display panel according to actual needs. In one example, the display panel can be a TDDI (Touch and Display Driver Integration) display panel.

[0065] The feature detection module 10 can calculate the feature value of the first frame data and the second frame data using an algorithm, and the feature value can uniquely identify each frame data (including the first frame data and the second frame data). For example, the feature value can be a CRC (Cyclic Redundancy Check), a Hash algorithm, a plaintext, or any other encoding that can identify the uniqueness of the frame data, and the present disclosure does not limit the feature value.

[0066] In some embodiments, the feature detection module 10 can also store the second feature value of the second frame data to facilitate comparison after the first feature value is determined. In some embodiments, the feature detection module 10 can further include a storage submodule for storing the second feature value and replacing the second feature value in the storage submodule with the first feature value after the comparison of the first feature value and the second feature value is completed, i.e., replacing the existing second feature value with the first feature value as a new second feature value for storage, so that the feature value of the previous frame data is always stored in the storage submodule, thereby improving the speed and efficiency of feature value comparison.

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

[0068] In the present embodiment, the data cycle arrangement rule is set according to the bit width of each pixel in the first frame data and the data flow of the display panel (Panel) displaying the first frame data. In some embodiments, the data cycle arrangement rule can be represented by nP (i.e., represented by n×P), where n represents the bit number of the pixel data, and P represents the data flow of the display panel. For example, assuming that the resolution of a display panel is 1920×1080, i.e., there are 1920 columns and 1080 rows of pixel points. If each pixel point uses 24 bits to represent color, then the data amount of each frame data is 1920×1080×24 bits. In this case, P=1920×1080, and n can be any integer value from 1 to 24 (i.e., n∈[1, 24]) according to actual needs.

[0069] The control module 30 is configured to stop the supply of the clock and / or power supply of the associated module in response to the enabled feature continuous signal. In this way, the feature continuous signal can be enabled when it is determined that the content displayed by the display panel does not change and the current content can continue to be displayed without frame data update, and then some front-end associated modules that do not participate in work in this case can be turned off to reduce power consumption.

[0070] The association module includes modules involved in processes 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, can be processor cores, communication interfaces or other functional modules), SRAM (Static Random Access Memory) and a storage controller (RAM control) for storing frame data, a DSC module (which is used for frame data compression according to the Display Stream Compression technology), a clock controller (Reset Clock Control, RCC), a power management unit (Power Management Unit, PMU), and the like, and the present disclosure does not make any limitation in this regard.

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

[0072] The source control component 40 is configured to be responsible for managing the source and flow direction of the data stream. It ensures that the data is processed in the correct order and at the right time, and coordinates the data transmission between different modules. Then the source control component 40 can be configured to, in response to the enabled feature continuous establishment signal, send the target frame data meeting the data cycle arrangement rule to the source driver 50. The source control component 30 is further configured to, in response to the turned-off feature continuous establishment signal, send the acquired next frame data to be displayed as the target frame data to the source driver 50. In response to the turned-off feature continuous establishment signal, the source control component 30 can send the next frame data to be displayed stored in the static random access memory SRAM and the like as the target frame data to the source driver 50.

[0073] In some embodiments, the cycle checking module 20 is further configured to store frame data meeting the data cycle arrangement rule. The frame data can be the first frame data, or the second frame data and the like meeting the data cycle arrangement rule. In this way, the source control component 40 can acquire the frame data meeting the data cycle arrangement rule from the cycle checking module 20 as the target frame data.

[0074] In some embodiments, the source control component 40 sends the frame data meeting the data loop arrangement rule as the target frame data to the source driver in any of the following manners:

[0075] sending the frame data meeting the data loop arrangement rule as the target frame data to the source driver 50 by built-in self test (BIST);

[0076] sending the frame data meeting the data loop arrangement rule as the target frame data to the source driver 50 by nP loop pattern generator;

[0077] sending the frame data meeting the data loop arrangement rule as the target frame data to the source driver 50 by storage controller.

[0078] The source driver 50 is configured 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 to drive components of the display panel to display content according to the target frame data.

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

[0080] In the embodiment, the electronic device can further include a data processing module, IPs, and a storage controller. The data processing module can be a processor or the like configured to process data to form frame data, and the present disclosure does not limit the data processing module. The storage controller is configured to store frame data from the IPs in a memory such as an SRAM under control of the IPs.

[0081] In this embodiment, IPs and the feature detection module 10 can respectively obtain frame data from the data processing module through their respective interfaces (IFs). The feature detection module 10 obtains the frame data from the data processing module through the corresponding IF interface and uses it as the first frame data for determining the first feature value. After obtaining the frame data, the IPs store it in a memory such as SRAM through a storage controller. Thus, the source control component 40 can obtain the frame data stored in the memory such as SRAM through the storage controller, or obtain the frame data stored by the feature detection module 10 that conforms to the data cycle arrangement rule. Then, based on whether the feature continuity signal is enabled, it can select to send the frame data stored in the feature detection module 10 that conforms to the data cycle arrangement rule or the frame data stored in the memory such as SRAM as the target frame data to the source driver.

[0082] The following combination Figures 2-4 The working principle and process of the display control device provided in the embodiments of this disclosure are illustrated below. Figure 3 This illustrates the data transfer process required to continuously acquire frame data to display content when the content displayed on the display panel changes. Figure 4 This illustrates the data transfer process for displaying content without constantly acquiring frame data to be displayed when the content on the display panel remains unchanged.

[0083] like Figure 2 As shown, in step S101, after frame data is formed in the data processing module, the frame data can be buffered according to the MIPI FIFO method (First In, First Out). Here, MIPI FIFO refers to the FIFO buffer used in the MIPI (Mobile Industry Processor Interface) interface IF for storing frame data. Then, as... Figures 3-4 As shown, IPs and feature detection module 10 can respectively obtain the first 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 into a memory such as SRAM.

[0084] like Figure 2 As shown, in step S102, the feature detection module uses 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 the comparison result, and so on. Figures 3-4 The comparison results are sent to the loop check module, as shown. Figures 3-4As shown, the cycle checking module further determines whether the comparison result is same, and if so, step S103 is performed. If the comparison result is different, the IPs and the feature detection module 10 respectively acquire the next frame data from the FIFO buffer through the corresponding interface IF in step S101.

[0085] As shown in step S102, the cycle checking module acquires the first frame data, and realizes data synchronization. Figure 2 As shown in step S103, the cycle checking module acquires the first frame data, and realizes data synchronization.

[0086] As shown in step S104, the cycle checking module determines whether the first frame data conforms to the preset data cycle arrangement rule if the comparison result is same. Figure 2 As shown in step S104, the cycle checking module determines whether the first frame data conforms to the preset data cycle arrangement rule if the comparison result is same. Figure 3 As shown, the source driving component acquires the frame data A through the storage controller in response to the off feature continuous signal, and sends the frame data A as the target frame data to the source driver. The source driver drives the display panel to display content according to the target frame data (i.e., the frame data A).

[0087] As shown in step S105, the cycle checking module stores the frame data that conforms to the data cycle arrangement rule last time. Figure 2 、 Figure 4 As shown in step S105, the cycle checking module stores the frame data that conforms to the data cycle arrangement rule last time.

[0088] As shown in step S106, the control module stops the supply of clock and / or power of the associated modules such as IPs, storage controllers, SRAMs, etc. in response to the enabled feature continuous signal, and reduces power consumption. Figure 2 、 Figure 4 As shown in step S106, the control module stops the supply of clock and / or power of the associated modules such as IPs, storage controllers, SRAMs, etc. in response to the enabled feature continuous signal, and reduces power consumption.

[0089] As shown in step S107, the source control component sends the frame data that conforms to the data cycle arrangement rule as the target frame data to the source driver in response to the enabled feature continuous signal. The source driver drives the display panel to display content according to the target frame data (i.e., the frame data that conforms to the data cycle arrangement rule). Figure 2 、 Figure 4 As shown in step S107, the source control component sends the frame data that conforms to the data cycle arrangement rule as the target frame data to the source driver in response to the enabled feature continuous signal. The source driver drives the display panel to display content according to the target frame data (i.e., the frame data that conforms to the data cycle arrangement rule).

[0091] The display unit comprises the display panel.

[0095] The first characteristic value of the first frame data to be displayed is determined, and a comparison result of the first characteristic value and a second characteristic value of second frame data is determined, the second frame data being a previous frame of the first frame data;

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

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

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

[0099] The associated module comprises a module involved in a process of processing, storing and transmitting the first frame data to the source control component.
