Description

Technical Field

[0001] This application relates to the field of electronic technology, specifically to a field sequence display control method, apparatus, and field sequence display device. Background Technology

[0002] Field Sequential Color LCD (FSC-LCD) is a type of liquid crystal display that can achieve color display without the use of a color filter (CF). Field sequencing utilizes a timing-controlled backlight to sequentially emit red, green, and blue backlights, correspondingly displaying red, green, and blue sub-pictures on the screen in that order. Within a very short timeframe imperceptible to the human eye, the persistence of vision allows for the presentation of a full-color image on the retina through time-varying color mixing. Field sequence color display technology is an integrated technology combining a field sequence backlight, fast-response liquid crystal, high-frequency driven TFT switches, and a color filter without color resist.

[0003] However, FSC-LCD suffers from severe color breakup (CBU), which seriously affects image quality. There is a relative velocity between the human eye and the image; the three sub-images (red, green, and blue) cannot completely overlap on the retina, resulting in color misalignment at the edges. This misalignment, after visual persistence integration, leads to color breakup.

[0004] Therefore, the technology still needs to be improved and enhanced. Summary of the Invention

[0013] In some embodiments of the field sequence display control method, the step of determining the candidate display order corresponding to the smaller driving load characteristic value as the target display order, and controlling the multi-frame sub-image data to be displayed sequentially according to the target display order to synthesize the current display frame includes: The candidate display order corresponding to the smaller drive load characteristic value is determined as the target display order; Determine the target display order and configure the target driving polarity corresponding to each frame of sub-image data; Multiple frames of sub-image data are displayed according to the target driving polarity and target display order to synthesize the current display frame.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Features thus defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0025] This application provides a field-sequence display control method, apparatus, and field-sequence display device. The method involves splitting the current display frame of video data into multiple sub-frames of image data and determining all candidate display orders for these sub-frames. Each sub-frame includes one color sub-frame and at least two monochrome sub-frames with different primary colors. Based on the grayscale difference characteristic value between adjacent sub-frames in each candidate display order and the driving polarity relationship between adjacent sub-frames, a driving load characteristic value for the corresponding candidate display order is determined. The candidate display order corresponding to the smaller driving load characteristic value is determined as the target display order, and the multiple sub-frames are controlled to be displayed sequentially according to the target display order to synthesize the current display frame. This alleviates the color separation phenomenon present in current field-sequence display devices, which affects display performance.

[0026] Please see Figure 1 This application provides a field sequence display control method, which includes steps S100 to S300, the specific steps of which are as follows: S100, the current display frame of the video data is split into multiple sub-frame image data, and all candidate display orders of the multiple sub-frame image data are determined; wherein, the multiple sub-frame image data includes one frame of color sub-image data and at least two frames of monochrome sub-image data with different primary colors.

[0027] In field-sequence color liquid crystal displays, a single frame of color image is typically decomposed into three monochrome subframes—red (R), green (G), and blue (B)—in a time sequence and displayed rapidly in rotation, utilizing the persistence of vision to synthesize a color image. However, this technique is prone to color separation, where distinct color edges are observed when the eye moves rapidly. To mitigate this phenomenon, this embodiment proposes adding a complete color sub-image frame to the existing monochrome sub-frames. Specifically, the current display frame of video data is split into multiple sub-image data frames, including one color sub-image frame and at least two monochrome sub-image frames with different primary colors. The color sub-image data is used to present the main brightness and color information of the image, while the other monochrome sub-image data is used to refine the image details. This approach maintains the advantages of field-sequence color display while suppressing color separation, thus improving the visual comfort and color blending of dynamic images.

[0028] Since the multi-frame sub-image data is displayed continuously in time, there is an objective display order. Taking the example of splitting an image into four sub-images (one color sub-image and three monochrome sub-images with different primary colors), these four sub-image data will form 4! = 24 different permutations and combinations when displayed, constituting the candidate display order.

[0029] S200. Determine the driving load characteristic value of the corresponding candidate display order based on the grayscale difference characteristic value between two adjacent frames of sub-image data in each candidate display order.

[0030] Adding a complete color sub-image to the existing monochrome sub-frame can suppress color separation to some extent, but its improvement is still limited by the response speed of the liquid crystal. The essence of accelerating the liquid crystal response speed lies in optimizing the pixel charging process of the liquid crystal display and shortening the switching time of liquid crystal molecules between gray levels, thereby reserving a more ample time window for backlight illumination.

[0031] Overdrive (OD) technology is used to improve the response time of displays. Its main purpose is to reduce the delay of liquid crystal molecules during grayscale transitions, thereby reducing image ghosting and blurring, especially in rapidly changing scenarios (such as games and video playback). The response time of an LCD monitor refers to the time required for liquid crystal molecules to switch from one state (grayscale) to another. This switching depends on voltage changes, but due to the inertia of the liquid crystal molecules, this switching process can be slow, especially the transition between grayscale levels (e.g., from light gray to dark gray). In the initial stage of liquid crystal molecule switching, a voltage higher than the target voltage is applied (i.e., the "overdrive" voltage). This excessive voltage accelerates the movement of the liquid crystal molecules, causing them to approach the target state more quickly. When the liquid crystal molecules approach the target state, the voltage quickly returns to normal levels to avoid overshoot or reverse oscillation. This process significantly shortens the time for liquid crystal molecules to switch from one grayscale to another, thus reducing image ghosting.

[0032] This application combines the liquid crystal inversion characteristics of a liquid crystal display with overdrive technology. By calculating the load requirements for liquid crystal inversion under different image data display conditions, the display order of multiple sub-frame image data is dynamically adjusted to optimize the display effect. Specifically, for each candidate display order, the driving load characteristic value corresponding to that candidate display order is determined based on the grayscale difference characteristic value between two adjacent sub-frame image data in each candidate display order. The grayscale difference characteristic value reflects the amplitude of liquid crystal molecule twisting between adjacent sub-frames; the greater the difference, the higher the required driving load. Based on this, the actual impact of different display orders on the liquid crystal response speed can be evaluated, thereby selecting the display order with the optimal driving load, fundamentally improving the liquid crystal response delay problem, and enhancing the overall dynamic display performance.

[0033] Please see Figure 2 In some embodiments, step S200 specifically includes steps S210 to S230, and the specific steps are as follows: S210. For each candidate display order, obtain the grayscale pixel value of each frame of sub-image data in two adjacent frames of sub-image data, and calculate the grayscale difference of multiple pixels in the two frames of sub-image data pixel by pixel.

[0034] Pixel grayscale differences reflect the degree of twisting required by liquid crystal molecules during switching: a greater difference means that the liquid crystal molecules need to deflect at a larger angle from the current state to the target state, requiring a higher driving voltage and placing more stringent load requirements on pixel charging and liquid crystal response. Specifically, for two adjacent frames of sub-image data, the system compares the grayscale values ​​at the same location in the two frames pixel by pixel, calculating the differences between them to obtain multiple pixel grayscale differences. In this embodiment, the grayscale differences at corresponding locations are calculated pixel by pixel to more accurately capture the change amplitude of each image between adjacent sub-frames.

[0035] S220. Determine the grayscale difference feature value between two adjacent sub-image frames based on the grayscale differences of multiple pixels.

[0036] The grayscale difference characteristic value reflects the magnitude of the twisting required for liquid crystal molecules to switch from displaying the previous frame to displaying the next frame. A larger difference value means that the liquid crystal molecules need to deflect more, and the requirements for driving voltage and response speed are also higher. Specifically, for each candidate display order, the grayscale difference characteristic value between each pair of adjacent sub-frames in that order is calculated sequentially, such as calculating the grayscale difference characteristic value between the first sub-frame and the second sub-frame, the second sub-frame and the third sub-frame, and so on.

[0037] The step of determining the grayscale difference feature value based on multiple pixel grayscale differences includes: determining the average value of the multiple pixel grayscale differences and using the average value as the grayscale difference feature value. For all corresponding pixels in two sub-image frames, the difference in their grayscale values ​​is calculated pixel by pixel to obtain multiple pixel grayscale differences; then, these pixel grayscale differences are statistically averaged to obtain the average value, which is used as the grayscale difference feature value between the two sub-image frames. This average value reflects the average grayscale change amplitude of adjacent sub-frames on the overall screen, and is used to characterize the average load degree that the liquid crystal molecules need to twist during switching.

[0038] The step of determining the grayscale difference feature value based on multiple pixel grayscale differences further includes: comparing the multiple pixel grayscale differences with a preset grayscale threshold; obtaining the number of differences greater than the preset grayscale threshold; and using the number of differences as the grayscale difference feature value. For all corresponding pixels in two adjacent sub-image frames, the grayscale difference is calculated pixel-by-pixel to obtain multiple pixel grayscale differences; then, these pixel grayscale differences are compared one by one with a preset grayscale threshold; the number of pixel differences greater than the preset grayscale threshold is counted to obtain the number of differences; finally, this number of differences is used as the grayscale difference feature value between the two sub-image frames. This feature value reflects the number of pixels where significant grayscale changes (i.e., large-scale torsion requirements) occur between adjacent sub-frames, characterizing the scale of the high-load area that liquid crystal molecules need to withstand during switching.

[0039] The step of determining the grayscale difference feature value based on the grayscale differences of multiple pixels further includes: squaring the grayscale differences of multiple pixels to obtain corresponding squared grayscale difference values; and summing the squared grayscale difference values ​​to obtain the grayscale difference feature value. First, for all corresponding pixels in two adjacent sub-image frames, the grayscale difference is calculated pixel-by-pixel to obtain multiple pixel grayscale differences; then, the grayscale difference of each pixel is squared to obtain corresponding squared grayscale difference values; finally, the squared grayscale difference values ​​of all pixels are summed, and the sum is used as the grayscale difference feature value between the two sub-image frames. This feature value amplifies the weight of larger grayscale differences through squaring, and can more sensitively reflect the overall influence of drastically changing areas in the image on the liquid crystal response speed.

[0040] S230. Determine the driving load feature value of the corresponding candidate display order based on the grayscale difference feature value between two adjacent sub-image frames.

[0041] Specifically, for each candidate display order, the grayscale difference feature value between each pair of adjacent sub-frame images in that order is calculated sequentially. The grayscale difference feature values ​​of all adjacent pairs of sub-frame images in the corresponding candidate display order are then summed, and the sum is the driving load feature value of that candidate display order. A lower driving load feature value indicates a smaller overall torsion amplitude of the liquid crystal under that candidate display order, resulting in a lighter driving load and contributing to faster response speeds and lower power consumption; conversely, a higher value may exacerbate response delay.

[0042] Please see Figure 3 In some other embodiments, step S200 specifically includes steps S201 to S203, and the specific steps are as follows: S201. For each candidate display order, obtain the grayscale feature value of each frame of sub-image data.

[0043] The step of obtaining the grayscale feature value of each frame of sub-image data includes: obtaining multiple pixel grayscale values ​​of each frame of sub-image data; determining the average value of the multiple pixel grayscale values, and using the average value as the grayscale feature value. In this embodiment, multiple pixel grayscale values ​​in a frame are simplified into a specific representative grayscale feature value. While preserving the overall brightness level of the frame image, this reduces the amount of data processing and computational complexity compared to obtaining multiple pixel grayscale differences pixel by pixel, thereby improving the overall efficiency of target display order filtering.

[0044] S202. Calculate the grayscale difference feature value between two adjacent sub-image frames based on the grayscale feature value.

[0045] For the candidate display order, after obtaining the grayscale feature value of each frame of sub-image data in the candidate display order, the grayscale feature values ​​between two adjacent frames of sub-image data are subtracted to obtain the corresponding difference value, and this difference value is used as the grayscale difference feature value between two adjacent frames of sub-image data.

[0046] S203. Determine the driving load characteristic value corresponding to the candidate display order based on multiple grayscale difference characteristic values.

[0047] After obtaining multiple grayscale difference feature values ​​for each candidate display order, the grayscale difference feature values ​​of all adjacent frames of sub-image data in the corresponding candidate display order are summed. The sum is the driving load feature value of that candidate display order. The lower the driving load feature value, the smaller the overall torsion amplitude of the liquid crystal under that candidate display order, the lighter the driving load, which helps to achieve faster response speed and lower power consumption; conversely, it may aggravate the response delay.

[0048] S300. Determine the candidate display order corresponding to the smaller drive load eigenvalue as the target display order, and control the multi-frame sub-image data to be displayed successively according to the target display order to synthesize the current display frame.

[0049] After calculating the drive load eigenvalues of all candidate display orders, perform the screening and display output of the optimal order. For example, select the candidate display order corresponding to the smallest drive load eigenvalue among multiple drive load eigenvalues as the target display order. Specifically, if the current display frame is synthesized by 4 frames of sub-image data (sub-frame A, sub-frame B, sub-frame C, sub-frame D), taking two of the candidate display orders as an example: Order 1 is sub-frame A → sub-frame B → sub-frame C → sub-frame D, and Order 2 is sub-frame A → sub-frame C → sub-frame B → sub-frame D. After calculation, the drive load eigenvalue L1 of Order 1 is 150, and the drive load eigenvalue L2 of Order 2 is 120. Since L2 < L1, Order 2 is taken as the target display order.

[0050] Subsequently, arrange the output timing of the 4 frames of sub-image data according to this target display order. First, write the data of sub-frame A into the pixel electrode, then write sub-frame C, then write sub-frame B, and finally write sub-frame D. When the four frames of sub-image data are successively displayed in the order of A → C → B → D, the human eye's visual persistence effect or backlight modulation fuses these four frames, and finally synthesizes the complete current display frame.

[0051] Of course, if there are multiple candidate display orders with the same and tied smallest drive load eigenvalues, one of them can be randomly selected as the target display order.

[0052] Since the selected target display order corresponds to a smaller drive load eigenvalue, the total torsional amplitude that the liquid crystal molecules need to experience during the entire display cycle is the smallest, or the torsional resistance is the lowest. The liquid crystal can reach the target gray-scale state faster, effectively shortening the response time, and the switching between adjacent frames is more sequential and smooth. Therefore, when the human eye tracks a moving object, the imaging position errors of the color, red, green, and blue sub-fields on the retina are compressed within the acceptable range of visual persistence, thereby effectively suppressing the occurrence of color separation phenomena and significantly improving the dynamic image quality of the field-sequential display.

[0053] In some embodiments, step S300 specifically includes: determining the candidate display order corresponding to the smaller drive load eigenvalue as the target display order; determining the target display order and configuring the target drive polarities corresponding to each frame of sub-image data; displaying the multi-frame sub-image data according to the target drive polarities and the target display order to synthesize the current display frame.

[0054] In this embodiment, after calculating the driving load characteristic values ​​for all candidate display orders, the optimal candidate display order is first selected as the target display order. After determining the target display order, a specific driving polarity is assigned to each frame of sub-image data according to a preset polarity reversal rule. The main basis for polarity configuration includes the principle of polarity alternation and adaptability to the target display order. For example, if a frame reversal method is used, and the driving polarity of the last sub-frame of the previous display frame is positive, then in the target order of the current display frame, the first frame (sub-frame A) should be configured as negative polarity, the second frame (sub-frame C) as positive polarity, the third frame (sub-frame B) as negative polarity, and the fourth frame (sub-frame D) as positive polarity. In this way, it is ensured that each sub-frame achieves correct polarity reversal relative to the previous frame, thereby alleviating the polarization phenomenon caused by liquid crystal molecules being subjected to the same electric field for a long time.

[0055] Once the drive polarity is configured, the sub-image data is output sequentially according to the target display order, while simultaneously controlling the charging voltage direction of the pixel electrodes based on the configured target drive polarity. For example, the data for sub-frame A is output with a negative drive polarity; the data for sub-frame C is output with a positive drive polarity; the data for sub-frame B is output with a negative drive polarity; and the data for sub-frame D is output with a positive drive polarity. After the four sub-image data frames are displayed in sequence, using the persistence of vision effect or backlight synchronization modulation, these four images are merged into a complete current display frame in the observer's eyes.

[0056] In this embodiment, by determining the target display order and configuring the corresponding driving polarity, it is ensured that the liquid crystal molecules not only deflect according to an optimal timing sequence but also according to the electric field direction that conforms to physical characteristics. This alleviates the liquid crystal response disorder caused by the change in polarity configuration due to the change in order. At the same time, the order with the smallest driving load characteristic value macroscopically reduces the total amplitude of liquid crystal torsion, while the precisely configured polarity microscopically optimizes the driving electric field for each frame. The combination of these two factors is beneficial for maximizing liquid crystal response, significantly suppressing dynamic image ghosting and color separation, and improving overall dynamic display performance.

[0057] Please see Figure 4 This application embodiment also provides a field sequence display control device, which includes: a data processing module 100, a pixel calculation module 200, and a display control module 300; the pixel calculation module 200 is connected to the data processing module 100, and the display control module 300 is connected to both the data processing module 100 and the pixel calculation module 200.

[0058] The data processing module 100 is used to split the current display frame of the video data into multiple sub-image data and determine all candidate display orders of the multiple sub-image data. The multiple sub-image data includes one frame of color sub-image data and at least two frames of monochrome sub-image data with different primary colors. The pixel calculation module 200 is used to determine the driving load feature value of the corresponding candidate display order based on the grayscale difference feature value between two adjacent sub-image data in each candidate display order. The display control module 300 is used to determine the candidate display order corresponding to the smaller driving load feature value as the target display order and control the multiple sub-image data to be displayed sequentially according to the target display order to synthesize the current display frame.

[0059] This application splits the current display frame of video data into multiple sub-frames of image data. These sub-frames include one frame of color sub-image data and at least two frames of monochrome sub-image data with different primary colors. The color sub-image data is used to present the main brightness and color information of the image, while the other monochrome sub-image data is used to refine the image details. This maintains the advantages of field-sequence color display while suppressing color separation, thus improving the visual comfort and color blending of dynamic images. Furthermore, by calculating the driving load characteristic values ​​under different display sequences, the display order of multiple sub-frames of image data is dynamically adjusted, fundamentally improving the liquid crystal response delay problem, effectively suppressing color separation, and significantly improving the dynamic image quality of the field-sequence display.

[0060] In some embodiments, the pixel calculation module 200 is further configured to, for each candidate display order, obtain the grayscale pixel value of each frame of sub-image data in two adjacent frames of sub-image data, and calculate multiple pixel grayscale differences between the two frames of sub-image data pixel by pixel; determine the grayscale difference feature value between two adjacent frames of sub-image data based on the multiple pixel grayscale differences; and determine the driving load feature value of the corresponding candidate display order based on the grayscale difference feature value between two adjacent frames of sub-image data.

[0061] In this application, the pixel processing module, based on all candidate display orders, acquires the grayscale pixel values ​​in each frame of sub-image data for each candidate display order, and calculates the grayscale difference between two frames of sub-image data at the same position pixel by pixel to obtain multiple pixel grayscale differences. Then, based on the multiple pixel grayscale differences, it calculates the grayscale difference feature value between two adjacent frames of sub-image data, and acquires all grayscale difference feature values ​​in the candidate display order for calculation to obtain the driving load feature value of that candidate display order, so that a better display order can be selected subsequently based on the driving load feature value.

[0062] Specifically, the pixel processing module is further used to determine the average value of multiple pixel grayscale differences after acquiring them, and use the average value as a grayscale difference feature value. Alternatively, it can compare multiple pixel grayscale differences with a preset grayscale threshold; obtain the number of differences greater than the preset grayscale threshold; and use the number of differences as a grayscale difference feature value. Alternatively, it can square the multiple pixel grayscale differences to obtain corresponding squared grayscale difference values; and sum the squared grayscale difference values ​​to obtain the grayscale difference feature value.

[0063] After acquiring the grayscale differences of multiple pixels, the pixel processing module can determine the grayscale difference feature value in various ways. Calculating the average of the grayscale differences of multiple pixels as the grayscale difference feature value can reflect the average level of grayscale changes between two adjacent sub-image frames. This method is simple to calculate, requires little computation, and is suitable for applications sensitive to overall brightness changes in the image. It can quickly assess the overall difference between two sub-image frames, providing basic data for subsequent calculation of drive load feature values. Alternatively, calculating the grayscale difference feature value using a preset grayscale threshold focuses on pixel areas where the change exceeds a certain level. This method can filter out the interference of minor changes on the evaluation results. When there is localized rapid motion in the image, this method can more accurately capture the areas that truly require high-load drive, offering a degree of targeting. Finally, squaring and summing the pixel grayscale differences can amplify the contribution of larger differences to the drive load feature value, while the impact of small changes is relatively weak. This method can more sensitively reflect the overall influence of drastically changing areas in the image on the liquid crystal response speed.

[0064] In another embodiment, the pixel processing module is further configured to acquire grayscale feature values ​​of each frame of sub-image data for each candidate display order; calculate grayscale difference feature values ​​between two adjacent frames of sub-image data based on the grayscale feature values; and determine the driving load feature values ​​of the corresponding candidate display order based on multiple grayscale difference feature values.

[0065] In this embodiment, multiple pixel grayscale values ​​in a single frame are simplified into a single representative grayscale feature value. Then, the grayscale feature values ​​between two adjacent sub-frames are subtracted to obtain the corresponding difference, which is used as the grayscale difference feature value between the two adjacent sub-frames. After obtaining multiple grayscale difference feature values ​​for each candidate display order, the grayscale difference feature values ​​of all adjacent sub-frames in the corresponding candidate display order are summed. The sum is the driving load feature value for that candidate display order. A lower driving load feature value indicates a smaller overall torsion amplitude of the liquid crystal under that candidate display order, resulting in a lighter driving load and contributing to faster response speed and lower power consumption; conversely, a higher value may exacerbate response delay.

[0066] In this embodiment, multiple pixel grayscale values ​​in a frame are simplified into a specific representative grayscale feature value. While preserving the overall brightness level of the frame image, this reduces the amount of data processing and computational complexity compared to obtaining the grayscale differences of multiple pixels pixel by pixel, thereby improving the overall efficiency of target display order filtering.

[0067] Please see Figure 5 This application embodiment also provides a field sequence display device, which includes one or more processors 10, a memory 20, and one or more application programs, wherein the one or more application programs are stored in the memory 20 and configured to be executed by the processor 10 to implement the above-described field sequence display control method. Since the field sequence display control method has been described in detail above, it will not be repeated here.

[0068] The processor 10 is the control center of the field sequence display device. It connects various parts of the display device through various interfaces and lines. By running or executing software programs and / or modules stored in the memory 20, and calling data stored in the memory 20, it performs various functions of the display device and processes data, thereby monitoring the field sequence display device as a whole.

[0069] The memory 20 can be used to store software programs and modules. The processor 10 executes various functional applications and data processing by running the software programs and modules stored in the memory 20.
