Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0049] The embodiments of the present application provide a screen data transmission and processing method, system, device and medium, which are used to more conveniently avoid afterimages on the display screen, without adding devices inside and outside the display panel, saving costs and being easy to implement.

[0050] Among them, the method, system, device and medium are based on the same application concept. Since the principles of solving problems by the method, system, device and medium are similar, the implementation of the device, device, medium and method can be referred to each other, and the repeated parts will not be described again.

[0051] The terms "first", "second", etc. (if any) in the description and claims of the embodiments of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily need to be used to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments described here can be implemented in an order different from that shown or described here. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0052] The following examples and embodiments are to be understood as illustrative examples only. Although this specification may refer to "one", "a", or "some" examples or embodiments in several places, this does not mean that each such reference relates to the same example or embodiment, nor that the feature applies only to a single example or embodiment. The individual features of different embodiments can also be combined to provide other embodiments. In addition, terms such as "including" and "comprising" should be understood not to limit the described embodiments to only those features that have been mentioned; such examples and embodiments can also include features, structures, units, modules, etc. that have not been specifically mentioned.

[0053] The following describes each embodiment of the present application in detail with reference to the accompanying drawings of the specification. It should be noted that the display order of the embodiments of the present application only represents the sequence of the embodiments, and does not represent the superiority or inferiority of the technical solutions provided by the embodiments.

[0054] Embodiments of the present application relate to a display device. Figure 1 It is a schematic diagram of an operation scenario between a display device and a control device according to an embodiment of the present application. As Figure 1 shown, the user can operate the display device 200 through the smart device 300 or the control device 100.

[0055] In some embodiments, the control device 100 can be a remote control. The communication between the remote control and the display device includes infrared protocol communication or Bluetooth protocol communication, and other short-distance communication methods, and the display device 200 is controlled by wireless or wired means. The user can input user instructions through buttons on the remote control, voice input, control panel input, etc. to control the display device 200.

[0056] In some embodiments, the smart device 300 (such as a mobile terminal, a tablet computer, a computer, a laptop, etc.) can also be used to control the display device 200. For example, an application program running on the smart device is used to control the display device 200.

[0057] In some embodiments, the display device 200 can also be controlled in a manner other than the control device 100 and the smart device 300. For example, it can directly receive the user's voice instruction control through a module for obtaining voice instructions configured inside the display device 200, or receive the user's voice instruction control through a voice control device provided outside the display device 200.

[0058] In some embodiments, the display device 200 also communicates with the server 400. The display device 200 is allowed to communicate and connect through a local area network (LAN), a wireless local area network (WLAN), and other networks. The server 400 can provide various contents and interactions to the display device 200. The server 400 can be a cluster or multiple clusters, and can include one or more types of servers.

[0059] Currently, most of the related technologies improve afterimages by adding external devices or from within the liquid crystal panel, which is costly and difficult. Therefore, in the embodiments of the present application, the TCON (Timing Controller) analyzes the characteristics of the screen, and the data detection module predicts whether there is an afterimage in the displayed image. When the image characteristics exceed the set threshold, the afterimage is improved by compensating the data of the sub-pixels (i.e., RGB sub-pixels) on the data line in the afterimage area.

[0060] See Figure 2 , the TCON 202 can process the input data value of the screen input by the SOC (System-On-a-Chip) 201 and then transmit it to the Driver 203, so that the display screen 204 can display the screen.

[0061] Therefore, the TCON knows the input Data value (i.e., RGB gray value) of each sub-pixel position of the image. The range of the inputData value is 0 to 255, which corresponds to the driving voltage of the Driver. The larger the input Data value, the larger the driving voltage. Therefore, the greater the voltage difference between the Vcom of the panel TFT (Thin Film Transistor), the stronger the electric field force of the TFT, and the easier it is to attract ions in the panel to form an afterimage.

[0062] Therefore, in the embodiments of the present application, the preset data threshold represents the critical voltage difference for generating an afterimage. For any sub-pixel position, when the input Data of the screen input by the SOC is greater than the data threshold, that is, when S-DataDiff>0 (where S-Data Diff = input data - data threshold), this sub-pixel will attract ions in the panel due to the electric field force of the TFT. When the number of attracted ions reaches a certain amount (the time of the electric field force action is proportional to the number of attracted ions), an afterimage will be generated.

[0063] Therefore, in some embodiments, see Figure 3, it can be set in the TCON: Data Detector 301, Position Marker 302, Frame Counter 303, and Compensation 304.

[0064] Among them, in some embodiments, the Data Detector module determines, for each sub-pixel on the data line, whether the value of the input data of the sub-pixel is greater than a preset data threshold, so as to prejudge whether the sub-pixel meets the condition of the electric field force magnitude for generating ghosting, that is, the Data Detection module 301 determines, for each sub-pixel, whether the condition S-Data Diff>0 is met.

[0065] In some embodiments, the Data Detection module 301 can further determine whether the input data difference between frames (i.e., F-Data Diff) of the sub-pixels that meet S-Data Diff>0 is zero, that is, for each sub-pixel that meets S-Data Diff>0, when the input data of the sub-pixel on the current frame image where the sub-pixel is located is different from the input data of the sub-pixel in its adjacent frame (the previous frame or the next frame) image (for example, expressed as F-Data Diff) is 0, that is, when F-Data Diff = 0, it means that the input data of the sub-pixel on the adjacent two frame images has not changed (that is, the electric field force has not changed).

[0066] Therefore, in some embodiments, the embodiments of the present application use the Position Marker 302 and the Frame Counter 303 to cooperate with the Data Detection module 301 to determine whether data compensation operations need to be performed.

[0067] Taking a 4K2K display as an example, it includes 3840 (rows) * 2160 (columns) sub-pixels, that is, there are 3840 data lines in the horizontal direction, numbered S1 to S3840, and each data line has 2160 sub-pixels in the vertical direction, numbered 1 to 2160. Then, the sub-pixel at any position on the display can be represented by the coordinate S(i,j), where i represents the row where the sub-pixel is located, and the value range is [1, 3840], and j represents the column where the sub-pixel is located, and the value range is [1, 2160].

[0068] Among them, in some embodiments, the detection result S-Data Diff of the data detection module 301 is transmitted to the position calibration module 302. When S-Data Diff>0, the position calibration module 302 records the coordinates of the sub-pixel, for example, as S(i,j), and feeds back the sub-pixel position S(i,j) to the data detection module 301. The data detection module 301 further determines whether the F-Data Diff of the sub-pixel S(i,j) is 0.

[0069] The data detection module 301 sends the judgment result of whether the F-Data Diff of the sub-pixel S(i,j) is 0 to the frame counting module 303. For the sub-pixel S(i,j), every time the frame counting module 303 receives that the F-Data Diff of the sub-pixel is 0, it accumulatively adds 1 to the frame count value corresponding to the sub-pixel (for example, denoted as Frame Counter). That is to say, the frame counting module 303 counts the electric field force action time in units of frames. Among them, the data detection module 301 can compare the input data of the same sub-pixel in the current frame and the previous frame, or compare the input data of the same sub-pixel in the current frame and the next frame to obtain the F-Data Diff corresponding to the sub-pixel. When the frame count value corresponding to the sub-pixel>the preset frame number threshold (frame threshold), it means that the condition of the electric field force action time for generating afterimages is satisfied, where frame threshold represents the preset frame number threshold (i.e., the electric field force action time threshold).

[0070] In summary, in some embodiments, when the sub-pixel S(i,j) satisfies the conditions: S-Data Diff>0 and FrameCounter>frame threshold, it is determined that the afterimage elimination process needs to be performed on the sub-pixel S(i,j). At this time, the frame counting module 303 sends the information of the sub-pixel S(i,j) that needs to be processed for afterimage elimination to the compensation module, including the coordinates S(i,j) of the sub-pixel and its frame count offset value (for example, denoted as Frame Cnt Diff), where Frame CntDiff is Frame Counter-frame threshold. And the data detection module 301 is also used to send the data offset value S-Data Diff of the sub-pixel S(i,j) to the compensation module 304.

[0071] In some embodiments, the compensation module 304 performs sub-pixel compensation according to the frame count offset value Frame Cnt Diff of the sub-pixel S(i,j) output by the frame counting module 303 and the data offset value S-DataDiff of the sub-pixel sent by the data detection module 301.

[0072] See Figure 4 , in some embodiments, the compensation module 304 includes: a data offset compensation module (Data DiffGain) 401, a frame count compensation module (Frame Cnt Gain) 402, and a data output module (Output data) 403.

[0073] In some embodiments, see Figure 5 , for the sub-pixel S(i,j), the data offset compensation module 401 determines the data offset compensation value (Data DiffGain) of the sub-pixel according to the magnitude of the data offset value (S-Data Diff) of the sub-pixel. When the S-Data Diff of the sub-pixel > 0, it is determined that the sub-pixel needs to be compensated. However, since the magnitudes of S-Data Diff are different, the intensities of compensation are also different. Therefore, the data offset compensation module 401 outputs different Data Diff Gains for different S-Data Diffs.

[0074] For example, the Data Diff Gain is solved by a first preset linear equation. Among them, S-Data Diff is equivalent to x in the equation. According to different x values, different compensation values y (i.e., Data Diff Gain) can be calculated. The first preset linear equation is, for example, y = kx + a, where k is the first preset weighting value and a is the first preset constant. It should be noted that the specific values of k and a can be determined according to actual needs and are not limited in the embodiments of the present application.

[0075] In some embodiments, see Figure 5 , for the sub-pixel S(i,j), the frame count compensation module 402 determines the frame count compensation value (FrameCnt Gain) corresponding to the sub-pixel according to the frame count offset value (Frame Cnt Diff) corresponding to the sub-pixel. When the Frame Counter corresponding to the sub-pixel > frame threshold, it is determined that the sub-pixel needs to be compensated. However, since the magnitudes of Frame Cnt Diff are different, the intensities of compensation are also different. Therefore, the frame count compensation module 402 outputs different Frame Cnt Gains for different Frame Cnt Diffs.

[0076] For example, Frame Cnt Gain is solved by a second preset linear equation of one variable. Among them, Frame Cnt Diff is equivalent to x in the equation. According to different x values, different compensation values y (i.e., Frame Cnt Gain) can be calculated. The second preset linear equation of one variable is, for example, y = px + b, where p is the second preset weighting value and b is the second preset constant. It should be noted that the specific values of p and b can be determined according to actual needs, and the embodiments of the present application do not limit them.

[0077] The data output module 403 determines the final output data, and the output data is calculated according to inputdata, Data Diff Gain, and Frame Cnt Gain, for example, using the following formula:

[0078] Output data = input data * (1 - Data Diff Gain * Frame Cnt Gain).

[0079] That is to say, referring to Figure 6 , finally, the data output module 403 in TCON 202 outputs the output data (for driving the sub-pixel) of the sub-pixel that needs data compensation obtained to the driver 203, so as to drive the sub-pixel, so that the finally displayed picture on the display screen 204 has no afterimage.

[0080] In summary, referring to Figure 7 , an image data transmission and processing method provided by an embodiment of the present application includes:

[0081] S101. Obtain the input data value of the picture sent by the system-on-chip SOC (such as the input Data value mentioned above); among them, the picture is the picture that needs to be output and displayed on the display screen;

[0082] S102. For each target sub-pixel on the display screen:

[0084] If it is determined that the sub-pixel meets the preset afterimage elimination condition based on the input data value corresponding to the sub-pixel, then determine the data for driving the sub-pixel (such as the Output data above) based on the input data value corresponding to the sub-pixel, the data offset value of the sub-pixel, and the frame count offset value of the sub-pixel; output the data for driving the sub-pixel to the driver of the display screen.

[0085] Among them, each target sub-pixel on the display screen can be each sub-pixel on the display screen or each sub-pixel within a preset area on the display screen.

[0086] In some embodiments, the preset afterimage elimination conditions include:

[0087] Condition 1: The data offset value of the sub-pixel (such as the above-mentioned S-Data Diff) is greater than zero;

[0088] Among them, the data offset value of the sub-pixel is the difference between the input data value corresponding to the sub-pixel and the preset data threshold (such as the above-mentioned data threshold).

[0089] In some embodiments, the preset afterimage elimination conditions further include:

[0090] Condition 2: The frame count offset value of the sub-pixel (such as the above-mentioned F-Data Diff) is greater than zero;

[0091] Among them, the frame count offset value of the sub-pixel is the difference between the frame count value of the sub-pixel (such as the above-mentioned FrameCounter) and the preset frame number threshold (such as the above-mentioned frame threshold); the frame count value of the sub-pixel is the number of consecutive frames in which the input data value corresponding to the sub-pixel remains unchanged.

[0092] It should be noted that in the embodiments of the present application, the preset afterimage elimination conditions may only include the above-mentioned Condition 1, may include both the above-mentioned Condition 1 and Condition 2, or may only include the above-mentioned Condition 2. The specific conditions are not limited in the embodiments of the present application.

[0093] In some embodiments, determining the data for driving the sub-pixel based on the input data value corresponding to the sub-pixel, the data offset value of the sub-pixel, and the frame count offset value of the sub-pixel includes:

[0094] Determining the data offset compensation value of the sub-pixel (such as the above-mentioned DataDiff Gain) based on the data offset value of the sub-pixel;

[0095] Determining the frame count compensation value of the sub-pixel (such as the above-mentioned FrameCnt Gain) based on the frame count offset value of the sub-pixel;

[0096] Determining the data for driving the sub-pixel (such as the above-mentioned Output data) based on the input data value corresponding to the sub-pixel, the data offset compensation value of the sub-pixel, and the frame count compensation value of the sub-pixel.

[0097] In some embodiments, determining the data offset compensation value of the sub-pixel based on the data offset value of the sub-pixel includes:

[0098] Based on the data offset value of the sub-pixel, use the first preset linear equation of one variable to determine the data offset compensation value of the sub-pixel;

[0099] Wherein, the first preset linear equation of one variable is y = kx + a, where y represents the data offset compensation value of the sub-pixel, x represents the data offset value of the sub-pixel, k is the first preset weighting value, and a is the first preset constant.

[0103] In some embodiments, determining the data for driving the sub-pixel based on the input data value corresponding to the sub-pixel, the data offset compensation value of the sub-pixel, and the frame count compensation value of the sub-pixel includes:

[0104] Use the following formula to determine the data for driving the sub-pixel:

[0105] Output data = input data * (1 - Data Diff Gain * Frame Cnt Gain);

[0106] Wherein, output data represents the data for driving the sub-pixel, input data represents the input data value corresponding to the sub-pixel, Data Diff Gain represents the data offset compensation value of the sub-pixel, and Frame Cnt Gain represents the frame count compensation value of the sub-pixel.

[0107] Of course, the above formula is only for illustration, and there may be other ways to determine the data for driving the sub-pixel. That is to say, in the embodiments of the present application, for the sub-pixels that meet the preset afterimage elimination conditions, it is equivalent to processing the input data sent by the SOC. On the basis of the input data sent by the SOC, add or subtract the compensation value obtained based on Data Diff Gain and Frame Cnt Gain, and output it to the driver after processing, so as to avoid the afterimage of the picture on the display screen.

[0108] The following introduces the system, device or apparatus provided by the embodiments of the present application. For the explanations or examples of the same or corresponding technical features as those described in the above method, they will not be repeated hereinafter.

[0109] In some embodiments, referring to Figure 8 , a transmission and processing system for screen data provided by the embodiments of the present application includes: a system-on-chip (SOC) 801, a timing controller (TCON) 802, and a driver 803; wherein, the TCON 802 is configured to:
