However, while achieving high-resolution display, these display modules need to transmit and process a large amount of display data per unit time, which poses huge challenges to the system's transmission bandwidth, computing power, and power consumption. Therefore, existing image display technologies generally face problems such as transmission bandwidth limitations, computing power limitations, and display performance bottlenecks, and are unable to achieve both high-resolution and high-refresh-rate display effects at the same time.

[0004] In order to overcome the above-mentioned defects of the prior art, the field urgently needs an improved image display data driving technology for multiplexing row scanning control signals with the same timing to synchronously light up multiple pixels with the same pixel value in the same display area, so as to improve the real-time performance of the row scanning drive display and reduce the actual display power consumption.

The third processing module 613 may be an application-specific integrated circuit (ASIC) chip, which is used to first parse the packet data and packet information in each data packet provided by the first processing module 611 of the previous stage to restore the resampled image, and perform various data processing such as optical distortion correction and screen uniformity compensation on the resampled image to preliminarily improve the image quality, and then repackage the display areas G i,j The packet data and packet information are then transmitted to the subsequent second processing module 612 for further data processing such as distortion correction, uniformity compensation, and / or optical compensation. In this way, the present invention can leverage the advantages of application-specific integrated circuit (ASIC) chips, such as low power consumption, small area, and high real-time performance, to further reduce the display power consumption of the image display driver and improve the real-time performance of image display.

The compression unit 112 may be provided at the front end or the back end of the grouping unit 111, and may be a lossy compression unit or a lossless compression unit. The compression unit 112 is mainly used to compress the image data to be transmitted based on storage space, so as to further reduce the data transmission bandwidth between the modules.

[0070] Specifically, taking the compression unit (Compressor) 112 provided at the rear end of the grouping unit 111 as shown in FIG. 2 as an example, in response to obtaining the data recorded in each display area G from the grouping unit 111, i，j For data packets containing packet data and packet information, the compression unit 112 can use n bytes (bits) to store the pixel value of a pixel according to a pre-agreed compression mode and / or compression ratio to obtain a compressed image with reduced storage space. Here, n is determined based on the color depth of the compressed image. Furthermore, for scenarios where no fixed compression mode and / or compression ratio has been pre-agreed, the compression unit 112 can also embed compression information such as the adopted compression mode and compression ratio into the above-mentioned data packets and efficiently transmit them along with the above-mentioned packet data and packet information in the form of a video stream to the back-end processing module 11 and / or display module 12.

[0071] In this way, the processing module 11 is combined with the grouping unit 111 that reduces the image data volume by reducing the resolution of the non-gaze point area and the compression unit 112 that reduces the image data volume by compressing the image color depth. The data transmission bandwidth between the processing module 11 and the display module 12 can be simultaneously reduced from the two dimensions of resolution and color depth, and the real-time performance of the image display can be further improved.

[0072] Furthermore, as shown in Figures 6B and 7 , for the first processing module 611 including the grouping unit 111 and the compression unit 112, the subsequent third processing module 613 may also include a decompressor 6131 and an ungrouping unit 6132. Furthermore, corresponding to the arrangement in which the grouping unit 111 is provided before the compression unit 112, the decompression unit 6131 may be provided before the ungrouping unit 6132. The decompression unit 6131 first decompresses the compressed data packets provided by the first processing module 611, and then the ungrouping unit 6132 decompresses the decompressed data packets to restore the resampled image. Subsequently, the third processing module 613 may perform at least one data processing operation, such as optical distortion correction for the lens module and screen uniformity compensation, via the display pipeline 6135 configured therein, to improve image quality.

[0073] In addition, in the embodiments shown in FIG6B and FIG7, the third processing module 613 may further include a compression unit 6133 and a grouping unit 6134. The compression unit 6133 may be provided before the grouping unit 6134, and is configured to first compress the previously restored resampled image, and then group and resample the compressed image to obtain a new image recording each display area G in the compressed image. i，j The data packets of the packet data and the packet information are transmitted one by one to the second processing module 612 at the subsequent stage.

[0074] As shown in Figures 6B and 8 , for the third processing module 613 including the compression unit 6133 and grouping unit 6134, the subsequent second processing module 612 may also include a depacketizing unit 6121 and a decompression unit 6122. Furthermore, corresponding to the arrangement in which the compression unit 6133 is provided before the grouping unit 6134, the depacketizing unit 6121 may be provided before the decompression unit 6122. The depacketizing unit 6121 first depacketizes the data packets provided by the third processing module 613 to restore the compressed image, and then decompresses the compressed image via the decompression grouping unit 6122 to restore the resampled image. The second processing module 612 can then perform at least one of the aforementioned data processing operations, such as distortion correction, uniformity compensation, and / or optical compensation, via the display pipeline 6125 configured therein, to further improve image quality.

[0075] In addition, in the embodiment shown in FIG6B and FIG8, the second processing module 612 may further include a grouping unit 6123 and a compression unit 6124. Here, the display module 621 adapted to the subsequent stage directly displays the image data according to the display area G.i,j In view of the characteristics of the grouped data and grouped information scanning and displaying the resampled image, the grouping unit 6123 in the last-level processing module 612 before the display module 621 should be located before the corresponding compression unit 6124, and is used to first group and resample the current resampled image, then compress the data packets obtained through the group resampling, and transmit the data packets of each frame of the resampled image to the subsequent display module 621 frame by frame, so that it can directly decompress the obtained data packets and scan and display the resampled image according to the decompressed data packets.

[0076] In addition, in the embodiments shown in Figures 7 and 8, in response to obtaining the video stream data provided by the pre-processing module, the third processing module 613 and / or the second processing module 612 can also preferably determine whether there is a local demand for data processing of the frame image.

[0077] In response to local data processing requirements for the image, the third processing module 613 and / or the second processing module 612 may parse the received data packets to obtain the packet data and packet information for each of the third processing module 613 and / or the second processing module 612. Based on the packet data and its corresponding packet information, the resampled image is restored to the resolution of the original image and the required data processing operations are performed based on the restored image. Subsequently, in response to the completion of the data processing operations, the third processing module 613 and / or the second processing module 612 may repackage the packet data and packet information for each frame of the resampled image as described above and transmit the data packets for each frame of the resampled image to the subsequent second processing module or display module, frame by frame.

[0078] On the contrary, in response to the fact that there is no local data processing demand for the image, the third processing module 613 and / or the second processing module 612 may not need to parse the data packet of the frame resampled image, but instead directly transmit it to the second processing module or display module at the next level to further reduce the data processing load of the image display and further improve the real-time performance of the image display.

[0079] Please continue to refer to Figures 6C, 6D, and Figures 9 to 11. Figure 9 shows a schematic diagram of the structure of a display module according to some embodiments of the present invention. Figure 10 shows a schematic diagram of a group parsing unit according to some embodiments of the present invention. Figure 11 shows a schematic diagram of column data and its corresponding scan control signals according to some embodiments of the present invention.

[0080] In the embodiment shown in FIG6C, FIG6D, and FIG9, the second display driver integrated chip (DDIC) 623 of the display module 12 is configured with a decompression unit 91, a packet parsing unit 92, a TCON (Timer Control Register) unit 93, a scan driver (Scan Driver) unit 94, and a source driver (Source Driver) unit 95. The decompression unit 91 can first obtain a compressed data packet from the second processing module 612 of the previous stage, decompress it, and then transmit it to the packet parsing unit 92 of the back end. The packet parsing unit 92 can read out the data packets of each display area G one by one according to the command terminator Command_end and the data terminator Data_end. i,j The group data and group information are respectively analyzed according to each group information to determine the display area G in the resampled image. i,j Afterwards, the group parsing unit 92 may input the multiple sets of column data into the source driving unit 95 at the back end, and input the scan control signal into the TCON unit 93 and the scan driving unit 94 at the back end, thereby transmitting each row scan control signal and its corresponding column data of at least one display area to the corresponding control line and corresponding data line of the display pixel array 622 via the source driving unit 95 and the scan driving unit 94, so as to synchronously light up each display area G according to each row scan control signal and its corresponding column data of at least one display area. i,j Multiple pixels in .

[0081] Specifically, as shown in FIG10 , in the process of parsing the above group data, the group parsing unit 92 may first determine at least one display area G corresponding to each group information. i,j The control line position and the data line position of the entire display pixel array 622 are then determined according to each group data and its corresponding at least one display area G. i,j The data line position of each display area G is generated respectively i,j Multiple sets of column data, and display area G according to each row i,0 ~G i,M-1 The smallest horizontal sampling rate, control line position and vertical sampling rate in each group information are used to generate corresponding row scanning control signals.

[0082] As shown in FIG11 , assuming that the pixel resolution of the original image is X×Y, the grouping information indicates that the image data involves N×M display areas G i,j , and each display area G i,j With x ij ×y ij pixel resolution, When the gaze point area Gi0,j0 The horizontal sampling rate and vertical sampling rate are [Hratio j0 , Vratio i0 ]=[1,1], the horizontal sampling rate and vertical sampling rate of the non-gaze point area are [Hratio j , Vratio i ]>[1,1], and the magnification increases as the distance from the gaze point increases, each display area G i，j According to the inverse of its horizontal sampling ratio 1 / Hratio[i, j] and the inverse of its vertical sampling ratio 1 / Vratio[i, j], it may have a corresponding number of at least one pixel value.

[0083] Thus, in the process of scanning and displaying the resampled image, the TCON unit 93 can control the same display area (eg G 1，0 ) has at least one first row scanning control signal of at least one data line with the same pixel value, generates the same first associated timing information, for controlling the display area (for example: G 1，0 ) at least one second row scanning control signal of at least one data line having another pixel value, generating the same second associated timing information, and controlling another display area (for example: G N-1，0 ) generates at least one third row scanning control signal of at least one data line with another pixel value, generating the same third associated timing information.

[0084] 9 and 10 , the TCON unit 93 can then input the associated timing information and row scan control signals to the back-end scan driver unit 94 to generate row scan control signals with the timing information. The scan driver unit 94 then sequentially transmits the corresponding row scan control signals to the control lines of the display pixel array 622 based on the associated timing information. Simultaneously, the TCON unit 93 or the scan driver unit 94 can also input the associated timing information to the source driver unit 95 as a synchronization signal. The source driver unit 95 then sequentially transmits the corresponding column data to the data lines of the display pixel array 622 based on the associated timing information and the synchronization signal. This synchronizes the input row scan control signals and illuminates the corresponding pixels in the display pixel array 622 in a synchronous manner.

[0085] At this time, since each display area G i,j The multiple pixels in the display pixel array 622 have the same pixel value and share the same associated timing information. The data line only needs to transmit one data to synchronously light up the corresponding multiple pixels in the display pixel array 622. In this way, each column data line only needs to transmit The scanning and display of a frame of resampled image can be completed by using only one piece of data, thereby effectively reducing the number of data transmissions, thereby reducing the time and power consumption of data transmission and scanning and display.

[0086] Furthermore, the present invention also provides multiple reference examples to more intuitively demonstrate the effects of the above-mentioned image display driving technology provided by the present invention. Please refer to Figure 12, which shows a timing diagram of scanning and displaying a resampled image according to some embodiments of the present invention.

[0087] As shown in FIG12 , compared to the left embodiment, which generates an independent timing sequence for each pixel and transmits the corresponding pixel value one by one to light up a corresponding pixel in the display pixel array 622, the right embodiment adopts a group resampling solution, which greatly reduces the pixel values ​​involved in the image without affecting the user's visual experience, and by providing the same display area G i,j By configuring multiple pixels in the same associated timing information, multiple pixels with the same pixel value in at least one display area are simultaneously illuminated. This reduces the number of data transmissions from 12 × 12 = 144 times in the left-hand solution to 3 × 12 = 36 times in the right-hand solution, effectively reducing data transmission and scanning display time and power consumption.

[0088] Those skilled in the art will understand that the structure of the display module shown in Figure 9 is only a non-limiting implementation method provided by the present invention, which is intended to clearly demonstrate the main concept of the present invention and provide a specific solution that is easy for the public to implement, rather than to limit the scope of protection of the present invention.

[0089] Alternatively, in the embodiments shown in FIG6A and FIG6B , for a display module such as a microdisplay 621 with a driving function, the decompression unit, packet parsing unit, TCON unit, scan driver unit, and source driver unit may be disposed within the microdisplay 621 along with the active area of ​​the display pixel array, and the same row scanning drive method may be implemented to similarly achieve the effect of scanning and displaying a resampled image. The principles of scanning and displaying a resampled image are similar to those of the aforementioned embodiments and will not be further elaborated upon herein.

[0090] In summary, the image display driver device, image display driver method, and computer-readable storage medium provided by the present invention can all perform group resampling of raw image data based on gaze point information and reuse row scan control signals with the same timing to synchronously illuminate multiple pixels with the same pixel value in the same display area, thereby improving the real-time performance of row scan driven display and reducing actual display power consumption. Furthermore, by first performing group resampling of raw image data based on gaze point information on the processing module side and then transmitting the obtained grouped data to the display module for display, the image display driver device, image display driver method, and computer-readable storage medium provided by the present invention can effectively reduce data transmission bandwidth and system transmission power consumption without affecting the visual effect of the image.
