[0065] For LCD panels supporting double-frequency display mode, taking a 4K resolution display panel with a 60Hz refresh rate as an example, the basic technical principle is as follows: The Timing Controller (TCON) can support two combinations of resolution and refresh rate: 4K×2K with a 60Hz refresh rate and 4K×1K with a 120Hz refresh rate. When using the 4K×1K 120Hz refresh mode, the System-on-Chips (SOC) simultaneously needs to enable 4K×1K output and use motion estimation and motion compensation (MEMC) processing at a 120Hz refresh rate before outputting to the TCON at the screen. Based on this technology, the image clarity and smoothness of high-speed motion scenes can be significantly improved. In existing technologies, a double-frequency display mode option is usually added to the menu, which the user manually selects to enable the double-frequency display function. However, in the existing solution, when displaying moving images, users sometimes forget to turn on the frequency multiplication display function, and some users are not even aware of the function, resulting in the frequency multiplication display function being idle.

[0066] To address the aforementioned technical problems, the inventors discovered that by comparing the motion speed of a target object in an image frame with a speed threshold, and automatically activating a double-frequency display mode based on the comparison result, a display device can be provided that improves the clarity and smoothness of moving images by comparing the motion speed of a target object in an image frame with a speed threshold and automatically activating a double-frequency display mode based on the comparison result, thereby enhancing the user experience.

[0067] The technical solutions of this application will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0068] The display device provided in this application embodiment may include: a controller and a display connected to the controller. The controller is used to acquire multiple image frames, perform recognition calculations on the multiple image frames to obtain the motion speed of a target object in the multiple image frames, compare the motion speed with a speed threshold corresponding to the target object, and if the motion speed is greater than or equal to the speed threshold, then activate the frequency multiplication display mode. The display is used to display image frames based on the frequency multiplication display mode after the frequency multiplication display mode is activated.

[0069] Specifically, multiple consecutive image frames to be displayed can be acquired, and recognition calculations can be performed on these frames. Various algorithms can be used for this recognition calculation; for example, the motion object recognition algorithm built into the MEMC module can be used, or an inter-frame image difference algorithm can be used to identify adjacent image frames. Through recognition calculations, the motion speed of the target object in the multiple image frames is obtained, and then the motion speed of the target object is compared with a corresponding speed threshold. When the motion speed of the target object is greater than the corresponding speed threshold, it indicates that there is a high-speed moving object in the current image, which is suitable for displaying the image using a frequency multiplication display mode. Therefore, the frequency multiplication display mode can be automatically enabled, allowing the display to show images containing high-speed moving objects based on this mode.

[0070] For example, the frame buffering capability of the SOC can be used to obtain multiple buffered image frames, and recognition calculations can be performed on these multiple image frames to find moving target objects. Then, the MEMC module of the SOC or the Frame Rate Control (FRC) module can be used to calculate the object position between consecutive frames to identify moving objects and relatively stationary objects. Figure 6 This is a schematic diagram showing adjacent image frames in a display device 200 according to one or more embodiments of this application. Figure 6 As shown, both the first and second image frames include objects A and B. Using the object recognition algorithm built into the MEMC module, comparing the positional changes of the objects in the two frames reveals that the center of object A has moved from O1 to O2, and object A has moved a distance to the lower right; therefore, object A is a moving object. The position of object B has not changed, making it a relatively stationary object.

[0071] In some embodiments, in addition to using the object recognition algorithm built into the MEMC module, an inter-frame image difference algorithm can also be used to perform recognition calculations on multiple image frames. Of course, both algorithms can be used simultaneously for mutual verification. For example, after recognizing a moving object using the MEMC module's pose-based object recognition algorithm, the recognition result can be further verified using an inter-frame image difference algorithm.

[0072] In some embodiments, when the controller obtains the motion speed of the target object in multiple image frames, it may specifically be used to: obtain the motion vector of the target object within multiple preset time periods; and determine the motion speed of the target object based on the multiple motion vectors.

[0073] There are multiple ways to determine the velocity of a target object based on multiple motion vectors.

[0074] In one possible implementation, the average value of multiple motion vectors can be calculated, and this average value can be determined as the velocity of the target object. Specifically, when the controller determines the velocity of the target object based on the multiple motion vectors, it can be used to: calculate the average value of the multiple motion vectors and determine the average value as the velocity of the target object.

[0075] In another possible implementation, multiple motion vectors can be compared, the maximum and minimum values ​​among them can be selected, the average of the maximum and minimum values ​​can be calculated, and then the average of the maximum and minimum values ​​can be determined as the velocity of the target object. Of course, the median value among multiple vectors can also be determined as the velocity of the target object. This embodiment does not limit this.

[0076] For example, taking a 30Hz input frame mode as an example, at time t, the object recognition algorithm built into the MEMC module can first be used to recognize and calculate multiple image frames cached by the SOC to identify moving objects. Then, inter-frame calculations are performed continuously using an inter-frame image difference algorithm to calculate the motion vector A1 of 30 image frames within t+1 seconds, then the motion vector A2 of 30 image frames within t+2 seconds, and so on, until the motion vector An of 30 image frames within t+n seconds is calculated. Next, the average value of A1, A2…An can be calculated, and this average value is determined as the velocity of the target object. Alternatively, the maximum and minimum values ​​can be selected from A1, A2…An, and the average of these values ​​can be determined as the velocity of the target object. Finally, the median value can be selected from A1, A2…An, and this median value is determined as the velocity of the target object.

[0077] In some embodiments, the speed threshold may be preset, and each moving object may use the preset speed threshold.

[0078] In some embodiments, to improve the accuracy of the judgment, a corresponding speed threshold can be set for each moving object, and the speed threshold can be dynamically obtained.

[0079] Before comparing the target object's motion speed with the corresponding speed threshold, the speed threshold can be calculated first using an inter-frame difference algorithm. Specifically, before acquiring multiple image frames, the controller can also: acquire multiple initial image frames; perform recognition calculations on the multiple initial image frames to obtain the initial motion speed of the target object; and determine the speed threshold based on the initial motion speed.

[0080] In some embodiments, when the controller obtains the initial motion speed of the target object, it may specifically be used to: obtain the initial motion vector of the target object within a plurality of preset time periods; and determine the initial motion speed of the target object based on the plurality of initial motion vectors.

[0081] There are multiple ways to determine the initial velocity of a target object based on multiple initial motion vectors.

[0082] In one possible implementation, the average value of multiple initial motion vectors can be calculated, and this average value can be determined as the initial velocity of the target object. Specifically, when the controller determines the initial velocity of the target object based on the multiple motion vectors, it can be used to: calculate the average value of the multiple initial motion vectors and determine the average value as the initial velocity of the target object.

[0083] In another possible implementation, multiple initial motion vectors can be compared, the maximum and minimum values ​​among them can be selected, the average of these maximum and minimum values ​​can be calculated, and then the average of the maximum and minimum values ​​can be determined as the initial velocity of the target object. Alternatively, the median value among the multiple vectors can also be used to determine the initial velocity of the target object. This embodiment does not limit this approach.

[0084] For example, taking a 30Hz input frame mode as an example, at time t, the object recognition algorithm built into the MEMC module can first be used to recognize and calculate multiple image frames cached by the SOC to identify moving objects. Then, inter-frame calculations are performed continuously using an inter-frame image difference algorithm to calculate the motion vector A1 of 30 image frames within t+1 seconds, then the motion vector A2 of 30 image frames within t+2 seconds, and so on, until the motion vector An of 30 image frames within t+n seconds is calculated. Next, the average value of A1, A2...An can be calculated, and this average value is determined as the initial velocity of the target object. Alternatively, the maximum and minimum values ​​can be selected from A1, A2...An, and the average of these values ​​can be determined as the initial velocity of the target object. Finally, the median value can be selected from A1, A2...An, and this median value can be determined as the initial velocity of the target object.

[0085] There are several ways to determine the speed threshold based on the initial motion speed.

[0086] In one possible implementation, the initial motion speed of the target object can be directly determined as the speed threshold of the target object. Specifically, when the controller determines the speed threshold based on the initial motion speed, it can be used to: determine the initial motion speed as the speed threshold.

[0087] In another possible approach, the initial velocity can be weighted and the weighted initial velocity can be determined as the velocity threshold.

[0088] Because the double-frequency display mode significantly improves the display effect of moving images, to ensure the accuracy of the timing of activating the double-frequency display mode, the scene to which the image frame belongs can be identified first. If the current scene is a high-speed motion scene, such as a racing game scene, then the motion speed and motion threshold are compared. Specifically, in some embodiments, before the controller identifies and calculates the initial motion speed of the target object from multiple initial image frames, it can also be used to: perform scene identification on at least one initial image frame; if the current scene is a high-speed motion scene, then identify and calculate the initial motion speed of the target object from multiple initial image frames.

[0089] For example, taking a 30Hz input frame mode as an example, the scene can first be identified using AI image recognition processing modules such as neural network models. When entering the game scene at time t, the object recognition algorithm built into the MEMC module can be used to identify and calculate multiple image frames cached by the SOC, completing the identification of moving objects. Then, continuous inter-frame calculations are performed using an inter-frame image difference algorithm to calculate the motion vector A1 of 30 image frames within t+1 seconds, then the motion vector A2 of 30 image frames within t+2 seconds, and so on, until the motion vector An of 30 image frames within t+n seconds is calculated. Next, the average value of A1, A2…An can be calculated, and this average value is determined as the initial velocity of the target object. Alternatively, the maximum and minimum values ​​can be selected from A1, A2…An, and the average of these values ​​can be determined as the initial velocity of the target object. Finally, the median value can be selected from A1, A2…An, and this median value can be determined as the initial velocity of the target object. Therefore, this initial velocity can be determined as the velocity threshold α.

[0090] After obtaining the speed threshold α, statistics are performed for n seconds. That is, the inter-frame image difference algorithm is used again to calculate the motion vectors B1, B2, ... Bn corresponding to t+n+1 seconds, t+n+2 seconds, ..., t+2n seconds respectively. If min(B1, B2, ..., Bn) ≥ α, the frequency multiplication display mode can be enabled, and the refresh rate can be increased to 120 Hz. If min(B1, B2, ..., Bn) < α, the normal refresh rate is maintained, such as 60 Hz, and the frequency multiplication display mode is not enabled.

[0091] In this embodiment, the value of n can be determined according to the actual effect and the speed of switching. For example, n can be set to 3.

[0092] In some embodiments, after the controller enables the frequency multiplication display mode, it can also be used to: perform scene recognition on the image frames displayed on the display; if the current scene is a non-high-speed motion scene, then disable the frequency multiplication display mode.

[0093] Specifically, for high-speed motion scenes, enabling the refresh rate mode can effectively improve the display effect of moving images. However, in non-high-speed motion scenes, or relatively static scenes, it can lead to poor image resolution, resulting in a noticeable decrease in clarity. Therefore, in scenes with less motion, enabling the refresh rate mode, such as a 4K×1K display with a refresh rate of 120Hz, will actually result in a decrease in clarity compared to a standard 4K×2K display with a refresh rate of 60Hz. Based on this, AI image recognition processing modules, such as neural network models, can be used to identify the currently displayed scene in real time. If the scene switches from a high-speed motion scene to a non-high-speed motion scene, the refresh rate mode can be turned off to avoid affecting the clarity of relatively static images.

[0094] If the current scene is detected to have switched from a non-high-speed motion scene to a high-speed motion scene again, the display control method provided in the above embodiments can be used to acquire multiple image frames, perform recognition calculations on the multiple image frames to obtain the motion speed of the target object in the multiple image frames, compare the motion speed with a speed threshold corresponding to the target object, and if the motion speed is greater than or equal to the speed threshold, then the frequency multiplication display mode is activated. Alternatively, before comparing the motion speed with the speed threshold corresponding to the target object, multiple initial image frames can be acquired, and recognition calculations can be performed on the multiple initial image frames to obtain the initial motion speed of the target object, and the speed threshold can be determined based on the initial motion speed.

[0095] In the specific implementation process, when the current scene is a high-speed motion scene with a large amount of movement, the double-frequency display mode can be automatically activated. For example, it can output a display mode with a resolution of 4K×1K and a refresh rate of 120HZ. The MEMC module also switches to the 4K×1K resolution and 120HZ refresh rate mode for motion compensation processing, thereby improving the clarity and smoothness of motion. When the current scene is a non-high-speed motion scene with little movement, the double-frequency display mode can be automatically deactivated. For example, at this time, it is no longer necessary to convert to the 4K×1K refresh rate 120HZ mode output. It can be displayed with only the effect of 4K×2K refresh rate 60HZ mode, so as not to affect the clarity of relatively stationary objects. The MEMC also automatically switches to the effect of 60HZ refresh rate. In this process, the user does not need to manually switch, thus improving the user's viewing experience.

[0096] The parameter settings for the normal display mode and the doubled refresh rate display mode with a resolution of 4K×2K and a refresh rate of 60Hz and a resolution of 4K×1K and a refresh rate of 120Hz described in the above embodiments are only examples. As long as the display panel supports it, the display control method executed by the above display device can also be migrated to an 8K resolution display panel for application. For example, the TCON specification initially supports a refresh rate of 60Hz for a resolution of 8K×4K and a refresh rate of 120Hz for a resolution of 8K×2K. The SOC can also perform corresponding switching processes according to the above principles: When the current scene is a high-speed motion scene with a large amount of movement, the double-frequency display mode can be automatically turned on. For example, it can output a display mode with a resolution of 8K×2K and a refresh rate of 120HZ. The MEMC module also switches to the 8K×2K resolution and 120HZ refresh rate mode for motion compensation processing, thereby improving the clarity and smoothness of motion. When the current scene is a non-high-speed motion scene with little movement, the double-frequency display mode can be automatically turned off. For example, at this time, it is no longer necessary to switch to the 8K×2K refresh rate of 120HZ mode for output. It can be displayed with the effect of 8K×4K refresh rate of 60HZ mode, which will not affect the clarity of relatively stationary objects. The MEMC also automatically switches to the effect of 60HZ refresh rate. In this process, the user does not need to manually switch, thus improving the user's viewing experience.

[0097] The above design principle can also be extended to 4K and 8K panels that are already 120Hz, except that the panel will support both 120Hz and 240Hz. The difference lies in the fact that, after enabling the frequency multiplication function, the refresh rate can be multiplied to 240Hz for 4K×1K resolution and 240Hz for 8K×2K resolution, respectively, achieving extremely high refresh rates.
