Moreover, the image screen displayed by the display module 120 may be projected onto a projection surface (such as the windshield of a vehicle) to display a projection screen. A user may view the projection screen reflected by the projection surface through the projection surface. The display module 120 may include a liquid crystal display, an OLED, a micro LED display, and so on. In this embodiment, the liquid crystal display includes a backlight module, and the backlight module has a light-emitting area formed by arranging a plurality of sub-light-emitting areas in an array, and the plurality of sub-light-emitting areas may each include one or more light-emitting units (such as light-emitting diodes (LEDs)).

[0039] Figure 2 is a flowchart of a display method of a head-up display according to an embodiment of the present disclosure. Refer to Figure 1 and Figure 2 , the head-up display 100 may perform the following steps S210 to S250. In step S210, the control module 110 may receive an original image. In step S220, the control module 110 may correct the image boundary of the original image according to the projection plane distortion data to generate a corrected image. In this embodiment, the control module 110 may correct the image boundary of the original image according to the preset projection plane distortion data so that the shape (boundary) of the projection screen displayed on the projection plane can form an appropriate undistorted screen, that is, the user can see a rectangular projection screen from the projection plane (such as the windshield of a vehicle). In one embodiment, the head-up display 100 may also include a sensor and may sense the projection plane distortion condition of the projection plane to generate corresponding projection plane distortion data.

[0040] In step S230, the control module 110 may determine a plurality of first sub-light-emitting regions corresponding to the image boundary of the corrected image. In step S240, the control module 110 may adjust the light-emitting data according to the display boundary data to increase the brightness values corresponding to the plurality of first sub-light-emitting regions in the light-emitting data, and set the brightness values of the plurality of second sub-light-emitting regions corresponding to the non-display regions in the light-emitting data to 0. In this embodiment, the control module 110 may increase the brightness of the pixels in the sub-light-emitting regions through which the image boundary of the display region of the corrected image passes, and turn off the pixels in the non-display regions outside the image boundary.

[0041] In step S250, the control module 110 may drive the display module 120 according to the corrected image and the adjusted light-emitting data.

[0042] Figure 3 is a schematic diagram of a head-up display according to an embodiment of the present disclosure. Refer to Figure 3 , the head-up display of the present disclosure can implement a head-up display 300 as shown in Figure 3 . The head-up display 300 includes a control module 310 and a display module 320. The control module 310 includes a controller 311, an image data receiving interface 312, a storage device 313, a display driving interface 314, and a light-emitting driving interface 315. The controller 311 is coupled to the image data receiving interface 312, the storage device 313, the display driving interface 314, and the light-emitting driving interface 315. The display module 320 includes a display panel 321 and a light-emitting module 322. The control module 310 may be coupled to the display panel 321 through the display driving interface 314. The control module 310 may be coupled to the light-emitting module 322 through the light-emitting driving interface 315. In this embodiment, the control module 310 may be a timing controller and may implement the functions of correcting the image boundary and adjusting the light-emitting brightness of the sub-light-emitting regions.

[0043] In this embodiment, the controller 311 can obtain the projection plane distortion data from the outside in advance. For example, the controller 311 can obtain the projection plane distortion data from a flash IC. The controller 311 can store the projection plane distortion data in the storage device 313. When the head-up display 300 is about to perform a display operation, the controller 311 can receive the original image provided by the image source through the image data receiving interface 312, and can read the projection plane distortion data from the storage device 313 to correct the shape of the image boundary of the original image according to the projection plane distortion data, and generate a corrected image. In other words, the shape of the image boundary of the original image can be different from the shape of the image boundary of the corrected image. Then, the controller 311 can judge the plurality of first sub-light-emitting regions of the light-emitting module corresponding to the image boundary of the corrected image according to the corrected image, so as to adjust the image boundary parameters in the light-emitting data according to the image boundary of the corrected image. The controller 311 can drive the display panel 321 through the display driving interface 314 according to the corrected image, and drive the light-emitting module 322 through the light-emitting driving interface 315 according to the adjusted light-emitting data.

[0044] Figure 4 is a schematic diagram of a head-up display according to another embodiment of the present disclosure. Refer to Figure 4 , the head-up display of the present disclosure can implement a head-up display 400 as shown in Figure 4 . The head-up display 400 includes a control module 410, a display module 420, and a processing chip 430. In this embodiment, the control module 410 includes a controller 411, an image data receiving interface 412, a storage device 413, a display driving interface 414, and a light-emitting driving interface 415. The controller 411 is coupled to the image data receiving interface 412, the storage device 413, the display driving interface 414, and the light-emitting driving interface 415. In this embodiment, the display module 420 includes a display panel 421 and a light-emitting module 422. The control module 410 can be coupled to the display panel 421 through the display driving interface 414. The control module 410 can be coupled to the light-emitting module 422 through the light-emitting driving interface 415. In this embodiment, the processing chip 430 includes a controller 431, an image data receiving interface 432, and an image data sending interface 433. The controller 431 is coupled to the image data receiving interface 432 and the image data sending interface 433. The processing chip 430 is coupled to the image data receiving interface 412 of the control module 410 through the image data sending interface 433.

[0045] In this embodiment, the controller 431 may obtain the projection plane distortion data from the outside in advance. For example, the controller 431 may obtain the projection plane distortion data from a flash memory chip. The controller 431 may store the projection plane distortion data in the storage device 413. When the head-up display 400 is about to perform a display operation, the controller 431 may receive the original image provided by the image source through the image data receiving interface 432, and may read the projection plane distortion data from the storage device 413 to correct the shape of the image boundary of the original image according to the projection plane distortion data, and generate a corrected image. Then, the controller 431 may send the image data of the corrected image to the image data receiving interface 412 of the control module 410 through the image data sending interface 433. Then, the controller 411 may determine the plurality of first sub-light-emitting regions of the light-emitting module corresponding to the image boundary of the corrected image according to the corrected image, so as to adjust the light-emitting data according to the image boundary of the corrected image. The controller 411 may drive the display panel 421 through the display driving interface 414 according to the corrected image, and drive the light-emitting module 422 through the light-emitting driving interface 415 according to the adjusted light-emitting data. In this embodiment, the control module 410 may be a timing controller, and the processing chip 430 may be a chip with image data operation function. In this embodiment, the control module 410 may implement the function of adjusting the light-emitting brightness of the sub-light-emitting regions, and the processing chip 430 may implement the function of correcting the image boundary.

[0046] Figure 5 is a schematic diagram of a corrected image according to an embodiment of the present disclosure. Refer to Figure 1 and Figure 5 , in this embodiment, the light-emitting region 510 of the light-emitting module of the display module 120 may include a plurality of sub-light-emitting regions arranged in an array. Taking Figure 5 the example of a plurality of sub-light-emitting regions of 10 columns and 6 rows shown. The display module 120 may provide backlight corresponding to the image region of the corrected image through at least a part of the sub-light-emitting regions of the light-emitting region 510. In this embodiment, the control module 110 may set the first sub-light-emitting region and the last sub-light-emitting region that overlap the image boundary 520 of the corrected image in each row of the plurality of sub-light-emitting regions in the light-emitting region 510 as the plurality of first sub-light-emitting regions.

[0047] As Figure 5As shown, taking the first row of the light-emitting region 510 as an example, the control module 110 can determine that the second sub-light-emitting region in the first row and the tenth sub-light-emitting region in the first row are the first sub-light-emitting region and the last sub-light-emitting region that overlap the image boundary 520 of the calibration image in this row. Therefore, the control module 110 can record this information (i.e., "2" and "10") into the boundary information 530. By analogy, taking the sixth row of the light-emitting region 510 as an example, the control module 110 can determine that the sixth sub-light-emitting region in the sixth row and the ninth sub-light-emitting region in the sixth row are the first sub-light-emitting region and the last sub-light-emitting region that overlap the image boundary 520 of the calibration image in this row. Therefore, the control module 110 can record this information (i.e., "6" and "9") into the boundary information 530. The control module 110 can store the boundary information 530 through two registers.

[0048] Accordingly, the control module 110 can adjust the light-emitting data according to the boundary information 530 to increase the brightness value corresponding to the sub-light-emitting regions recorded in the boundary information 530, and adjust the brightness values of other sub-light-emitting regions outside the range of the sub-light-emitting regions recorded in the boundary information 530 to 0.

[0049] Figure 6 It is a driving schematic diagram of the pixel array of the embodiment of the present disclosure. Refer to Figure 1 and Figure 6 , the control module 110 can drive the display module 120 according to the adjusted light-emitting data. A part of the light-emitting region 620 of the light-emitting module of the display module 120 can include multiple light-emitting units P(1,1) to P(4,4) as shown in Figure 6 . Taking Figure 6 as an example, the image boundary 611 of the calibration image 610 can overlap multiple light-emitting units P(2,4), P(3,3), P(4,2) of multiple sub-light-emitting regions of the display module 120, for example. And, the non-display region outside the image boundary 611 can correspond to multiple light-emitting units P(3,4), P(4,3), P(4,4). Therefore, the control module 110 can increase the brightness of the light-emitting units P(2,4), P(3,3), P(4,2), and set the brightness values of the light-emitting units P(3,4), P(4,3), P(4,4) to 0.

[0050] In this regard, in one embodiment, the control module 110 can multiply the brightness values corresponding to the light-emitting units P(2,4), P(3,3), P(4,2) in the light-emitting data by a preset value to generate adjusted brightness values, where the preset value is greater than 1. And, the control module 110 can adjust the light-emitting data so that the light-emitting units P(3,4), P(4,3), P(4,4) do not emit light (i.e., turn off or do not drive the light-emitting units P(3,4), P(4,3), P(4,4)).

[0051] Therefore, since the brightness values of the light-emitting units P(3,4), P(4,3), and P(4,4) corresponding to the non-display area are set to 0, the light-emitting units P(3,4), P(4,3), and P(4,4) will not cause light leakage. Also, since the brightness of the light-emitting units P(2,4), P(3,3), and P(4,2) located at the boundary of the display area is increased, the edge brightness of the image screen in the display area can be effectively compensated.

[0052] Figure 7 is a schematic diagram of a corrected image according to another embodiment of the present disclosure. Refer to Figure 1 and Figure 7 , in one embodiment, the light-emitting area 710 of the light-emitting module of the display module 120 may include a plurality of sub-light-emitting areas arranged in an array. Taking Figure 7 the plurality of sub-light-emitting areas of 10 columns and 6 rows shown as an example. The display module 120 may provide backlight corresponding to the image area of the corrected image through at least a part of the sub-light-emitting areas in the light-emitting area 710. In this embodiment, the control module 110 may set the first sub-light-emitting area and the last sub-light-emitting area of each of the plurality of consecutive overlapping sections in each row of the plurality of sub-light-emitting areas in the light-emitting area 710 overlapping the image boundary 720 of the corrected image as the plurality of first sub-light-emitting areas.

[0053] As Figure 7 shown, taking the first row of the light-emitting area 710 as an example, the control module 110 may determine that the first sub-light-emitting area and the tenth sub-light-emitting area of the first row are the first sub-light-emitting area and the last sub-light-emitting area of the consecutive overlapping sections in this row overlapping the image boundary 720 of the corrected image. Therefore, the control module 110 may record this information (i.e., "2" and "10") into the boundary information 730. By analogy, taking the sixth row of the light-emitting area 710 as an example, the control module 110 may determine that the first sub-light-emitting area and the third sub-light-emitting area of the sixth row are the first sub-light-emitting area and the last sub-light-emitting area of the consecutive overlapping sections in this row overlapping the image boundary 720 of the corrected image, and may also determine that the eighth sub-light-emitting area and the tenth sub-light-emitting area of the sixth row are another first sub-light-emitting area and another last sub-light-emitting area of the consecutive overlapping sections in this row overlapping the image boundary 720 of the corrected image. Therefore, the control module 110 may record this information (i.e., "1", "3", "8", and "10") into the boundary information 730. The control module 110 may store the boundary information 730 through four registers.

[0054] Accordingly, the control module 110 can adjust the light emission data according to the boundary information 730 to increase the brightness value of the sub-light-emitting area corresponding to the boundary information 730, and adjust the brightness value of other sub-light-emitting areas outside the range of the sub-light-emitting area recorded by the boundary information 730 to 0.

[0055] Figure 8 is a flowchart of a display method of a head-up display according to another embodiment of the present disclosure. Refer to Figure 3 and Figure 8 , the head-up display 300 can perform the following steps S810 to S850. In step S810, the controller 310 can download the projection plane distortion data. The controller 310 can read the projection plane distortion data from an external flash memory chip, for example. In step S820, the controller 310 can update the projection plane distortion data stored in the storage device 313. In step S830, the controller 310 can determine whether it is necessary to adjust a plurality of first sub-light-emitting areas (that is, adjust the area position information of the sub-light-emitting areas overlapping the image boundary of the corrected image). If so, in step S840, the controller 310 can update the projection plane distortion data. If not or after the update is completed, in step S850, the controller 310 corrects the original image and adjusts the light emission data. Therefore, the head-up display 300 can effectively correct the image distortion displayed on the projection plane and improve the problem of light leakage.

[0056] In summary, the display method of the head-up display and the head-up display of the present disclosure can automatically correct the image boundary of the image according to the distortion of the projection plane to improve the problem of image distortion. And, the display method of the head-up display and the head-up display of the present disclosure can automatically increase the brightness of the boundary of the display area corresponding to the image boundary of the image after distortion correction, and set the brightness of the non-display area to 0. In this way, the problem of light leakage in the projection screen can be effectively improved.
