Description

Display panel and electronic device Technical Field

[0001] The present application relates to the field of display technology, and in particular to the manufacture of display modules, and specifically to display panels and electronic devices. Background Art

[0002] Micro LED (Micro Light Emitting Diode Display) is a thin-film, miniaturized, and arrayed LED structure design, which can be applied to micro-display fields such as virtual reality, augmented reality, projection, helmet display, and head-up display.

[0003] Currently, a digital subfield scanning method is commonly used to drive Micro LED displays. This means that a frame can be divided into multiple subframes with different weights. Different weights indicate different luminous durations for the corresponding subpixels. The corresponding luminous or non-luminous state is then determined by the value of each subframe. The luminous durations of multiple subframes are then superimposed to present the grayscale brightness corresponding to the frame. However, for a subframe with a larger weight, when a subpixel does not emit light in one of the subframes and emits light in the other, the duration of the subframe with the larger weight is longer, meaning that the brightness of the subpixel changes significantly when switching between the non-luminous and luminous states. This can cause flickering, reducing the quality of the displayed image.

[0004] Therefore, the existing digital sub-field scanning method for display driving has the problem of screen flickering, which is in urgent need of improvement. SUMMARY OF THE INVENTION

It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] The present application provides a display panel, which includes but is not limited to the following embodiments and combinations of the following embodiments.

[0026] In one embodiment, as shown in FIG1 , the display panel 100 includes: a plurality of sub-pixels 10; a frame buffer module 20 for caching a plurality of bit-plane data corresponding to a frame to be displayed for each of the sub-pixels; as shown in FIG2 , the plurality of bit-plane data include a plurality of first bit-plane data D1; each first bit-plane data is used to control the corresponding sub-pixel to continuously emit light or not emit light within a corresponding (n1*T), wherein n1 is an integer greater than 1, and different first bit-plane data correspond to different values ​​of n1, and the value of n1 is related to the storage bit of the corresponding first bit-plane data; and T is a reference duration; a source driver module 30, electrically connected between the frame buffer module and the plurality of sub-pixels, for reading each first bit-plane data at least once and at least one first bit-plane data at least twice within the corresponding frame to be displayed, and each time the first bit-plane data is read, it is used to control the corresponding sub-pixel to continuously emit light or not emit light within the T.

[0027] For ease of description, an example of a plurality of sub-pixels arranged along rows and columns is used herein for illustration, but the arrangement is not limited to this. Specifically, as shown in FIG1 , the display panel may further include a gate driver module 40, a plurality of gate lines 50, and a plurality of data lines 60. Each gate line may be connected between a corresponding output terminal of the gate driver module and a corresponding row of sub-pixels to transmit a corresponding gate signal to the row of sub-pixels. Each data line may be connected between a source driver circuit and a corresponding column of sub-pixels to transmit a corresponding data signal to the column of sub-pixels.

[0028] As shown in FIG1 , the display panel may include a panel body 01 and a driver chip 02 electrically connected to the panel body. The panel body may include the aforementioned multiple sub-pixels, multiple data lines, and multiple gate lines. The driver chip may include the aforementioned frame buffer module and source driver module. Furthermore, the driver chip may also include a timing control module 70 electrically connected to the frame buffer module and the gate driver module. The timing control module may be used to acquire image signals, and the image data may be processed by the timing control module or the frame buffer module to generate "multiple bit plane data" corresponding to each frame to be displayed. In this embodiment, there is no limitation on whether the gate driver module is included in the panel body or the driver chip. FIG1 only takes the gate driver module included in the former as an example for illustration.

[0029] Among them, the multiple bit plane data corresponding to a frame to be displayed in this embodiment can be understood as follows: in the conventional digital sub-field scanning method, a frame to be displayed can be divided into multiple initial sub-frames arranged in sequence (corresponding one to one to multiple bit plane data), that is, the duration of time that each bit plane data can control the sub-pixel to continue to emit light or not emit light, the value of n1 in "(n1*T)" is related to the storage bit of the initial sub-frame, and the weights corresponding to different storage bits are also different. It can also be considered that the sub-pixel in each initial sub-frame is acted upon by the corresponding bit plane data with corresponding weights to emit light or not. For example, the frame to be displayed can be divided into 8 initial sub-frames ("bit 0" to "bit 7") as shown in Figure 2, that is, 8 bit-plane data can be provided corresponding to each frame to be displayed, and the number of bit-plane data can be equal to the number of initial sub-frames. Each bit-plane data is stored in a corresponding storage bit. It can be considered that the 8 bit-plane data corresponding to "bit 0" to "bit 7" have the corresponding 8 storage bits increasing in sequence, for example, the storage bit of "bit 0" is the "0th bit" (the lowest bit), and the storage bit of "bit 7" is the "7th bit" (the highest bit). The higher the storage bit, the larger the corresponding value of n1 (that is, the larger the weight).

[0030] In combination with the above discussion, each first bit of plane data is used to control the corresponding sub-pixel to continuously emit light or not within the corresponding (n1*T), n1 is an integer greater than 1, and the value of n1 corresponding to different first bit of plane data is different. When the frame to be displayed is divided into 8 initial sub-frames ("bit 0" to "bit 7") as shown in Figure 2, if the initial sub-frames corresponding to the reference time length T of the three are set to "bit 6", "bit 5", and "bit 4" respectively, then the setting method of the weights corresponding to the other initial sub-frames of the three are also different, but they all conform to the weights increasing sequentially from "bit 0" to "bit 7".

[0031] It should be noted that the examples of several setting methods for the initial subframe corresponding to the reference duration T in Figure 2 will all result in the existence of initial subframes with weights less than 1, but this embodiment does not limit whether there are initial subframes with weights less than 1 and their corresponding bit-plane data (i.e., different from the first bit-plane data). For example, if the initial subframe corresponding to the reference duration T is set to "bit 7", there are no initial subframes with weights less than 1 and their corresponding bit-plane data.

[0032] Specifically, as shown in FIG2 , when the initial subframe corresponding to the reference duration T is set to “bit 6”, the weights of “bit 0” to “bit 7” may be (1 / 64), (1 / 32), (1 / 16), (1 / 8), (1 / 4), (1 / 2), 1, and 2, respectively. The bit-plane data corresponding to “bit 7” having a weight greater than 1 (i.e., in accordance with the value of n1) may be defined as the first bit-plane data. Furthermore, in this embodiment, at least one first bit-plane data (here only corresponding to “bit 7”) is read at least twice, and each time the first plane data is read, it is used to control the corresponding sub-pixel to continuously emit light or not emit light within T, that is, the same first plane data is read twice, and each reading only uses the reference time T with a weight of 1 to limit the time for the sub-pixel to emit light or not emit light. This can avoid the sub-pixel using the originally larger weight of the first plane data (greater than 1, that is, the corresponding n1 is greater than 1) to control the sub-pixel to emit light or not emit light for a longer time (that is, the corresponding n1*T), thereby reducing the time for the sub-pixel to emit light or not emit light, and reducing the risk of the sub-pixel flickering when switching to another non-luminous or luminous state in the frame to be displayed.

[0033] Similarly, as shown in FIG2 , when the initial subframe corresponding to the reference duration T is set to “bit 5”, the weights of “bit 0” to “bit 7” may be (1 / 32), (1 / 16), (1 / 8), (1 / 4), (1 / 2), 1, 2, and 4, respectively. The bit-plane data corresponding to “bit 6” and “bit 7” with a weight greater than 1 (i.e., in accordance with the value of n1) may all be defined as first-plane data. In this case, this embodiment may read at least one first-plane data (here corresponding to at least one of “bit 6” and “bit 7”) at least twice. Similarly, as shown in FIG2 , when the initial subframe corresponding to the reference duration T is set to “bit 4”, the weights of “bit 0” to “bit 7” may be (1 / 16), (1 / 8), (1 / 4), (1 / 2), 1, 2, 4, and 8, respectively. The bit-plane data corresponding to “bit 5” and “bit 7” with a weight greater than 1 (i.e., in accordance with the value of n1) may all be defined as first-plane data. In this case, the embodiment may read at least one first-plane data (here corresponding to at least one of “bit 6” and “bit 7”) at least twice. 7” can be defined as first-plane data. In this case, this embodiment can read at least one first-plane data (here corresponding to at least one of “bit 5” to “bit 7”) at least twice.

[0034] Combined with the above analysis, the frame to be displayed is divided into 8 initial subframes ("bit 0" to "bit 7”) as an example, compared with the conventional digital sub-field scanning method, this embodiment is based on the fact that when the initial sub-frame corresponding to the reference time length T has been set, for the first bit-plane data with a weight greater than 1, the sub-pixel is no longer controlled to emit light or not by scanning the sub-pixel only once. Instead, the weight value (i.e., n1) is used as the number of times the first bit-plane data is read. That is, the above-mentioned gate driving module is used to scan the same sub-pixel multiple times in the frame to be displayed, and the number of times the same sub-pixel is scanned is equal to the number of times the source driving module reads multiple bit-plane data (greater than or equal to the sum of the weights corresponding to all the first bit-plane data, because it is also necessary to consider that each bit-plane data with a weight less than or equal to 1 also needs to be read once); wherein, the gate driving module scans the sub-pixel each time so that the source driving module loads the corresponding read bit-plane data into the sub-pixel; wherein, the gate driving module is used to scan the sub-pixel at least twice (equal to the weight of the corresponding first bit-plane data, i.e., the corresponding value of n1) so that the source driving module loads the corresponding read first bit-plane data into the sub-pixel twice.

[0035] Furthermore, as shown in FIG2 , the plurality of bit-plane data further include at least one second bit-plane data D2, each second bit-plane data being used to control the corresponding sub-pixel to continuously emit light or not emit light within the corresponding (n2*T), wherein n2 is greater than 0 and less than or equal to 1, and different second bit-plane data correspond to different values ​​of n2; each time the source driver module reads the second bit-plane data, it is used to control the corresponding sub-pixel to continuously emit light or not emit light within the (n2*T). In combination with the above discussion, it can be considered that the plurality of bit-plane data further include at least one second bit-plane data D2 corresponding to at least one initial sub-frame with a weight less than 1, and each second bit-plane data is used to control the corresponding sub-pixel to continuously emit light or not emit light within a period less than the reference duration.

[0036] Specifically, combined with the above discussion, it can be seen that since the source driver module reads the first bit of plane data once each time, it is only used to control the corresponding sub-pixel to continuously emit light or not emit light within the reference time length T. Therefore, it can be considered that each first bit of plane data needs to be read n1 times, so as to write to the corresponding sub-pixel n1 times to perform n1 times of continuous light emission or non-light emission within the reference time length T, in order to achieve the brightness equivalent to the conventional 1 write to the corresponding sub-pixel to perform 1 time of continuous light emission or non-light emission within (n1*T); and the source driver module can control the corresponding sub-pixel to continuously emit light or not emit light within (n2*T) each time it reads the second bit of plane data, so the second plane data only needs to be read once.

[0037] Continuing from the previous paragraph, if it is defined that each time the source driver module reads the bit-plane data to write into the corresponding sub-pixel is counted as a target sub-frame, that is, in this embodiment, the frame to be displayed can be divided into multiple target sub-frames with equal periods (i.e., equal to the reference duration T) (the number is equal to the sum of the number of times the source driver module reads the bit-plane data, and also equal to the sum of the values ​​of n1 of all the first-plane data). For example, when the initial sub-frames corresponding to the reference duration T in Figure 2 are set to "bit 6", "bit 5", and "bit 4", respectively, the number m of target sub-frames corresponding to the three are 9, 12, and 19, respectively.

[0038] In one embodiment, as shown in FIG2 , a plurality of first bit-plane data in the bit-plane data are arranged sequentially. For two adjacent first bit-plane data, the value of n1 corresponding to one of the first bit-plane data is h times the value of n1 corresponding to the other first bit-plane data, where h is a positive integer greater than 1. As discussed above, each bit-plane data is stored in a corresponding storage bit, and a higher storage bit has a larger corresponding n1 value (i.e., a larger weight). Therefore, for two adjacent first bit-plane data, the values ​​of n1 are different, meaning that the source driver module reads the first bit-plane data the number of times it reads them. Here, the source driver module may read the first bit-plane data with a larger n1 value (a higher storage bit) the number of times it reads the first bit-plane data with a smaller n1 value (a lower storage bit).

[0039] Specifically, for example, when h is equal to 2, it indicates that the weight of one of the two adjacent first-plane data is twice the weight of the other. For example, in the three target subframe division methods shown in FIG2 , the weight of the later bit (i.e., the value of n1) of "bit 0" to "bit 7" is twice the weight of the earlier bit (i.e., the value of n1). Of course, the value of h is not limited in this embodiment. For example, when h is equal to 3, it indicates that the weight of one bit is three times the weight of the other, and the sum of the durations (n1*T) of the first bit used to control the subpixel's lighting or non-lighting in the frame to be displayed is three times that of the latter bit. As discussed above, 2 is the minimum value of h. This minimizes the difference in the durations of two adjacent first-plane data used to control the subpixel's lighting or non-lighting in the same frame to be displayed, thereby improving the weight difference between the two adjacent first-plane data and enhancing the accuracy of the division of the durations of controlling the subpixel's lighting or non-lighting in the corresponding initial subframe.

[0040] For example, as shown in FIG3 , multiple bit plane data corresponding to a frame to be displayed are shown. Here, a frame including four initial subframes ("bit 0" to "bit 3") is taken as an example for explanation, where the weights of "bit 0" to "bit 3" increase sequentially, the values ​​of n2 corresponding to "bit 0" and "bit 1" are (1 / 2) and 1, and the values ​​of n1 corresponding to "bit 2" and "bit 3" are 2 and 4, respectively. That is, the duration for which the subpixel emits light or does not emit light in multiple initial subframes is equal to (1 / 2)*T, T, 2T, and 4T, respectively. Similarly, for example, as shown in FIG4 , which is a plurality of bit plane data corresponding to a frame to be displayed, the frame including 8 initial sub-frames (“bit 0” to “bit 7”) is taken as an example for explanation, where the weights of “bit 0” to “bit 7” increase sequentially, the values ​​of n2 corresponding to “bit 0” to “bit 4” are (1 / 16), (1 / 8), (1 / 4), (1 / 2), and 1, respectively, and the values ​​of n1 corresponding to “bit 5” to “bit 7” are 2, 4, and 8, respectively. That is, the duration for which the sub-pixel emits light or does not emit light in the multiple initial sub-frames is equal to (1 / 16)*T, (1 / 8)*T, (1 / 4)*T, (1 / 2)*T, T, 2T, 4T, and 8T, respectively.

[0041] In one embodiment, as shown in FIG3 and FIG4 , the plurality of first bit-plane data include at least one first-type first-plane data D11 and (taking at least two of “bit 3” in FIG3 and “bit 5” to “bit 7” in FIG4 as examples, for example, both being equal to a first value) at least one second-type first-plane data D12 (taking at least “bit 2” in FIG3 and “bit 5” to “bit 7” in FIG4 as examples that are different from at least two of the first-type first-plane data, for example, both being equal to a second value). One of each first-type first-plane data and each second-type first-plane data is used to control the corresponding sub-pixel to continuously emit light within the corresponding (n1*T), and the other is used to control the corresponding sub-pixel to continuously not emit light within the corresponding (n1*T). The source driver module is configured to read the second-type first-plane data at least once during at least two readings of the same first-type first-plane data or during at least two readings of at least two different first-type first-plane data.

[0042] As discussed above, each first-bit plane data is used to control the corresponding sub-pixel to continuously emit light or not emit light within the corresponding (n1*T). Here, the first-bit plane data used to control the corresponding sub-pixel to continuously emit light or not emit light within the corresponding (n1*T) can be defined as the first type of first-bit plane data (for example, equal to one of the first value and the second value) and the second type of first-bit plane data (for example, equal to the other of the first value and the second value).

[0043] Specifically, as shown in Figure 3, "bit 3" and "bit 2" are taken as examples corresponding to the first type of first bit plane data and the second type of first bit plane data, respectively. Combined with the above discussion, it can be seen that the two need to be read 4 times (respectively, from the number of times "b3-1" to the number of times "b3-4") and 2 times (respectively, from the number of times "b2-1" to the number of times "b2-2"), respectively. Then, they can be read in the order shown in Figure 5 (from left to right). If the two second bit plane data "bit 0" and "bit 1" are taken into account (not limited to controlling whether the corresponding sub-pixels emit light or not), the second type of first bit plane data can be read once (i.e., the number "b2-1") between the number of times "b3-2" and the number of times "b3-3" (the order is not limited).

[0044] Similarly, as shown in FIG4 , “bit 7” and “bit 5” are taken as examples corresponding to the first type of first-plane data and the second type of first-plane data, respectively. Combined with the above discussion, it can be seen that the two need to be read 8 times (from times “b 7-1” to times “b 7-8”) and 2 times (from times “b 5-1” to times “b 5-2”, respectively). Then, they can be read in the order shown in FIG6 (from left to right). If the five second-bit plane data “bit 0” to “bit 4” are taken into account (not limited to controlling whether the corresponding sub-pixels emit light or not), the second type of first-plane data can be read once (i.e., times “b 5-1”) between times “b 7-5” and times “b 7-6” (the order is not limited).

[0045] Therefore, the phrase "in the process of at least two times..." in this embodiment can be understood as: (1) reading the same or different first-type bit-plane data at least twice; and (2) in the entire process of performing at least two readings as above, inserting and reading the second-type first-type bit-plane data once in at least any two adjacent readings.

[0046] It can be understood that in this embodiment, in the process of multiple readings of the same first-type first-plane data used to control the sub-pixel to continuously emit light or not emit light within the corresponding reference time length T, or in the process of separately reading two different first-type first-plane data used to control the sub-pixel to continuously emit light or not emit light within the corresponding reference time length T, the reading of the second-type first-plane data used to control the sub-pixel to continuously not emit light or emit light within the corresponding reference time length T is inserted to reduce the duration that the sub-pixel emits light or does not emit light in the frame, thereby reducing the risk of the sub-pixel flickering when switching to another non-luminous or luminous state in the frame to be displayed.

[0047] Of course, in this embodiment, the specific reading order of the first type first plane data and the second type first plane data is not limited. It is only necessary to insert the reading of the second type first plane data into the process of reading the same or different first type first plane data multiple times.

[0048] Specifically, FIG3 and FIG5 are used as examples for explanation. FIG7 and FIG8 are timing diagrams of the sub-scanning fields corresponding to FIG5 and FIG6 respectively. The circuit diagram shown in FIG9 can be referred to for discussion (transistors T1 to T4 constitute a storage module, the gates of transistors T5 and T6 are loaded with a scan signal Scan and a clear signal Clear respectively, and the input terminals of transistors T5 and T6 are loaded with a data signal Data (for controlling the emission of sub-pixels) and a low-voltage signal V respectively). GL(used to control the sub-pixel not to emit light), the output ends of both transistors T5 and T6 are connected to the gates of both transistors T5 and T6, and the gate of transistor T7 is connected to the gates of both transistors T1 and T2.) "Scan" and "Clear" in Figures 7 and 8 represent the scan-valid pulse of the scan signal and the clear-valid pulse of the clear signal, respectively. "Scan" and "Clear" are used to control the sub-pixel to emit light or not in the corresponding time period (initial sub-frame or target sub-frame), respectively.

[0049] For example, as shown in Figures 3 and 7, in each initial subframe ("bit 0" to "bit 3"), multiple scan valid pulses are generated in sequence to scan multiple rows of sub-pixels in sequence. As discussed above, based on the luminous duration of "bit 1" as the reference duration T, the luminous durations of the sub-pixels in the two initial subframes "bit 2" to "bit 3" are equal to 2T and 4T respectively. For example, in "bit 1", multiple "Scan"s control multiple rows of sub-pixels to be scanned in sequence, and each row of sub-pixels is maintained for T after being scanned, that is, in "bit 2", multiple "Scan"s control multiple rows of sub-pixels to be scanned in sequence again. The sub-pixels scanned first in "bit 1" are also scanned first in "bit 2", otherwise they are also scanned later, so as to ensure that the duration (i.e., luminous duration) of each sub-pixel after being scanned in the same initial subframe is the same; and "bit 2" The luminous duration of the sub-pixels in the initial sub-frame of "bit 0" is equal to (1 / 2)*T. Therefore, it is necessary to load corresponding multiple "Clear" and then act on multiple rows of sub-pixels for (1 / 2)*T (that is, the non-luminous duration) after multiple "Scan" actions to turn off the multiple rows of sub-pixels, thereby controlling the multiple rows of sub-pixels to not emit light within the second (1 / 2)*T of "bit 0".

[0050] It should be noted that, as shown in FIG7 , since the duration of the heavier-weighted “bit 3” is too long, if the luminous state of the sub-pixel changes when switching between the initial sub-frame of “bit 3” and other adjacent initial sub-frames, as discussed above, flickering may occur, resulting in poor display quality.

[0051] Differently, as shown in, for example, FIG5 and FIG8 of the present application, since the initial subframe is divided into multiple target subframes, in each subframe (“bit 0”, “bit 1”, “each of b 2-1” to “b 2-2”, and each of “b 3-1” to “bit 3-4”), the scanning signal sequentially scans multiple rows of sub-pixels to scan multiple sub-pixels (equivalent to scanning the multiple target subframes divided according to each initial subframe, which was originally scanned only once to present the corresponding initial subframe). Based on the luminous duration of “bit 1” as the reference duration T, the luminous duration of the sub-pixels corresponding to each of “bit 2-1” to “bit 2-2” and each of “b 3-1” to “b 3-4” is also equal to T. For example, when the multiple target subframes are arranged in the order shown in FIG5 , in “bit 1”, multiple “Scan” sequentially controls the scanning of multiple rows of sub-pixels, and each row of sub-pixels is maintained at T after scanning, that is, in “bit 1”, the luminous duration of “bit 1” is equal to T. In the scan of "b 3-4" after "bit 1", multiple "Scan" controls the scanning of multiple rows of sub-pixels in sequence again. The sub-pixels scanned first in "bit 1" are also scanned first in "b 3-4", otherwise they are also scanned later, to ensure that the duration (luminescence duration) of each sub-pixel after scanning in the same sub-frame is the same; and the luminescence duration of the sub-pixels in the initial sub-frame of "bit 0" is equal to (1 / 2)*T. Therefore, multiple "Clear" controls are required to act on multiple rows of sub-pixels for (1 / 2)*T after the "Scan" action to turn off the multiple rows of sub-pixels, thereby controlling the multiple rows of sub-pixels to not emit light within the second (1 / 2)*T of "bit 0".

[0052] It can be understood that, as shown in Figure 8, since the weight of each target subframe divided can be considered to be the same in this application, that is, the duration of action on the sub-pixel is the same, when the sub-pixel switches between every two adjacent target subframes, as discussed above, since it avoids reading all the same or different first-type first-bit plane data in sequence at one time (for example, at least by reading the second-type first-bit plane data corresponding to "bit 1", the one-time continuous reading of "b 3-1" to "b 3-4" is destroyed), the flickering phenomenon in Figures 3 and 7 can at least be improved.

[0053] In summary, the source driver module in this embodiment reads the same first-type first plane data (both equal to the first value, such as "bit 3" in FIG. 3 or one of "bit 5" to "bit 7" in FIG. 4) at least twice or reads at least two different first-type first plane data (both equal to the second value, such as two of "bit 5" to "bit 7" in FIG. 4) at least twice, and reads the second-type first plane data (such as "bit 2" in FIG. 3 or "bit 5" to "bit 7" in FIG. 4) at least once. 7" is different from at least one of the first-type first-plane data), it is possible to avoid reading the same first-type first-plane data at least twice in succession or reading different first-type first-plane data at least twice in sequence, thereby avoiding causing the sub-pixel to emit light or not emit light for at least (2*T) in the frame to be displayed. Instead, the second-type first-plane data is interspersed in the process to interrupt the continuous emission or non-emission of the sub-pixel, so as to reduce the duration of the continuous emission or non-emission of the sub-pixel in the frame to be displayed, thereby reducing the risk of flickering of the sub-pixel when switching to another non-emission or emission state in the frame to be displayed.

[0054] In one embodiment, as shown in Figures 3 to 6, when the source driver module is configured to read the second-type first-plane data at least once during at least two reads of the same first-type first-plane data, the value of n1 corresponding to the first-type first-plane data is greater than the value of n1 corresponding to the second-type first-plane data. It is understood that in this embodiment, the value of n1 corresponding to the second-type first-plane data used for interleaved reading is further limited to be smaller than the value of n1 corresponding to the second-type first-plane data being interleaved, thereby preventing the originally corresponding first-type first-plane data, which has a higher weight, from being read continuously all at once, thereby improving the aforementioned worst-case flickering problem.

[0055] For example, comparing Figures 3 and 5, during the reading of "b 3-1" to "b 3-4" corresponding to "bit 3" with a larger weight (the order is not limited), the reading of "b 2-1" in "bit 3" with a smaller weight will be inserted; for another example, comparing Figures 4 and 6, during the reading of "b 7-1" to "b 7-8" corresponding to "bit 7" with a larger weight (the order is not limited), the reading of "b 5-1" in "bit 5" with a smaller weight will be inserted.

[0056] In one embodiment, as shown in FIG3 to FIG6 , the source driver module is further configured to read the first-type first-plane data at least once between two reads of the same second-type first-plane data or two reads of two different second-type first-plane data. It will be appreciated that in this embodiment, the at least one read of the first-type first-plane data is inserted to avoid continuously reading all identical or different second-type first-plane data at once. Similarly, the aforementioned flicker problem caused by continuously reading all identical or different second-type first-plane data at once can also be addressed, thereby further improving the flicker problem.

[0057] In one embodiment, similarly, "a plurality of first bit-plane data include at least one first-type first bit-plane data", and at least one second bit-plane data also includes at least one first-type second bit-plane data, and one of the first-type first bit-plane data and the first-type second bit-plane data is used to control the corresponding sub-pixel to continuously emit light within the corresponding (n1*T) or the corresponding (n2*T), and the other is used to control the corresponding sub-pixel to continuously not emit light within the corresponding (n1*T) or the corresponding (n2*T); wherein, the source driver module is used to read the first-type second bit-plane data at least once between reading the same first-type first bit-plane data twice or reading two different first-type first bit-plane data twice.

[0058] Among them, "at least one of the second bit-plane data also includes at least one first type second bit-plane data, one of the first type first bit-plane data and the first type second bit-plane data is used to control the corresponding sub-pixel to continuously emit light within the corresponding (n1*T) or the corresponding (n2*T), and the other is used to control the corresponding sub-pixel to continuously not emit light within the corresponding (n1*T) or the corresponding (n2*T)" can be understood as: (1) one of the first type first bit-plane data and the first type second bit-plane data is used to control the corresponding sub-pixel to emit light, and the other is used to control the corresponding sub-pixel not to emit light; (2) the first type first bit-plane data and the first type second bit-plane data act on the corresponding sub-pixel for different durations, which are (n1*T) and (n2*T) respectively.

[0059] For example, if the first-bit plane data of the first category is used to control the corresponding sub-pixel to emit light within the corresponding (n1*T), then the second-bit plane data of the first category is used to control the corresponding sub-pixel not to emit light within the corresponding (n2*T); for another example, if the first-bit plane data of the first category is used to control the corresponding sub-pixel not to emit light within the corresponding (n1*T), then the second-bit plane data of the first category is used to control the corresponding sub-pixel to emit light within the corresponding (n2*T).

[0060] Similarly, in this embodiment, in the process of multiple readings of the same or different first-type first-bit plane data for controlling the sub-pixel to continuously emit light or not emit light within the corresponding reference time length T, the reading of the first-type second-bit plane data for controlling the sub-pixel to continuously not emit light or emit light within the corresponding time length (equal to (n2*T), less than the reference time length T) is inserted, so as to reduce the time length that the sub-pixel emits light or does not emit light within the frame, thereby reducing the risk of the sub-pixel flickering when switching to another non-luminous or luminous state in the frame to be displayed.

[0061] For example, comparing Figure 3 and Figure 5, in the process of reading "b 3-1" to "b 3-4" corresponding to the first-bit plane data of the first category (the order is not limited), for example, the reading of the first-bit plane data of the first category may be inserted once (i.e., the number "b 0") between the number "b 3-1" and the number "b 3-2"; for another example, comparing Figure 4 and Figure 6, in the process of reading "b 7-1" to "b 7-8" corresponding to the first-bit plane data of the first category (the order is not limited), for example, the reading of the first-bit plane data of the first category may be inserted once (i.e., the number "b 3") between the number "b 7-1" and the number "b 7-2".

[0062] In one embodiment, based on the above-mentioned first-type first-plane data, second-type first-plane data and first-type second-plane data, the difference is that the first-type second-plane data and the second-type first-plane data are respectively used to control the corresponding sub-pixels to continuously emit light or not within the corresponding (n2*T) and the corresponding (n1*T) (that is, both the first-type second-plane data and the second-type first-plane data are used to control the sub-pixels to emit light or not); wherein the source driver module is used to read the second-type first-plane data at least once between respectively reading the first-type second-plane data and the first-type first-plane data.

[0063] Among them, "the first type of second-bit plane data and the second type of first-bit plane data are respectively used to control the corresponding sub-pixels to continuously emit light or not emit light within the corresponding (n2*T) and the corresponding (n1*T)" can be understood as: (1) the first type of second-bit plane data and the second type of first-bit plane data are both used to control the corresponding sub-pixels to emit light or not emit light; (2) the first type of second-bit plane data and the second type of first-bit plane data act on the corresponding sub-pixels for different durations, which are (n2*T) and (n1*T) respectively.

[0064] For example, if the first bit plane data of the second category is used to control the corresponding sub-pixel to emit light within the corresponding (n1*T), then the second bit plane data of the first category is used to control the corresponding sub-pixel to emit light within the corresponding (n2*T); for another example, if the first bit plane data of the second category is used to control the corresponding sub-pixel not to emit light within the corresponding (n1*T), then the second bit plane data of the first category is used to control the corresponding sub-pixel not to emit light within the corresponding (n2*T).

[0065] It can be understood that in this embodiment, between reading the first type of second-bit plane data and the first type of first-bit plane data, which are both used for the sub-pixel to emit light or not, the reading of the second type of first-bit plane data for the sub-pixel to emit light or not is inserted. This can also reduce the duration of the sub-pixel emitting light or not in the frame, and reduce the risk of the sub-pixel flickering when switching to another non-emitting or emitting state in the frame to be displayed.

[0066] For example, comparing Figure 3 and Figure 5, the source driver module can read the second-category first-plane number (for example, the number of times "b 3-2" corresponding to "bit 3") at least once between respectively reading the first-category second-bit-plane data (for example, "bit 0") and the first-category first-plane data (for example, the number of times "b 2-1" corresponding to "bit 2"); for another example, comparing Figure 4 and Figure 6, the source driver module can read the second-category first-plane number (for example, the number of times "b 7-2" corresponding to "bit 7") at least once between respectively reading the first-category second-bit-plane data (for example, "bit 3") and the first-category first-plane data (for example, the number of times "b 6-1" corresponding to "bit 6").

[0067] In one embodiment, the display panel has multiple frames to be displayed, and in two different frames to be displayed, the source driver module reads the respective multiple first bit-plane data in different orders. Specifically, the multiple bit-plane data shown in FIG4 can have multiple reading orders as shown in FIG10. For a still image (which can be considered as multiple frames (Frame 1 to Frame 4) of the same initial display data being arranged continuously), in this embodiment, the multiple first bit-plane data within the same "multiple bit-plane data" are read in different orders in different frames. In this way, even if one frame still exhibits a slight flicker, since the sub-pixels in the multiple frames corresponding to the still image switch between emitting and not emitting light differently in each frame (i.e., the arrangement order of the multiple target sub-frames is different), the switching pattern of the sub-pixels between emitting and not emitting light in the multiple frames can be staggered to extend the period of differentiation of the multiple frames, further reducing the risk of flicker.
