Referring to FIG. 1, the display system 100 includes a processing circuit 110, an image source 120, a switching signal source 130, and a display panel 140. The processing circuit 110 is coupled to the image source 120, the switching signal source 130, and the display panel 140. In this embodiment, the display system 100 can achieve both autostereoscopic and 2D display functions, although the present invention is not limited thereto. In this embodiment, the processing circuit 110 may receive image data S1 from the image source 120 and a switching signal S2 from the switching signal source 130. In this embodiment, the switching signal S2 may be used by the processing circuit 110 to determine whether to drive the display panel 140 to perform a 3D display mode or a 2D display mode. The processing circuit 110 may determine whether to correct the image data S1 based on the switching signal S2, and may generate a corresponding drive signal S3 for the display panel 140 based on the uncorrected image data S1 or the corrected image data S1.

[0017] In this embodiment, the processing circuit 110 may be a display driver chip and may have a memory unit for storing the correction algorithm 111. In one embodiment, the processing circuit 110 may include, for example, a central processing unit (CPU), a graphics processing unit (GPU), or other programmable general-purpose or special-purpose microprocessor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a programmable logic device (PLD), or other similar processing circuit or combination of devices. Additionally, the memory unit may include a memory and / or a database. The memory unit may be, for example, a non-volatile memory (NVM). The memory unit may store the correction algorithm 111 or related programs, modules, systems, or image data for implementing various embodiments of the present invention, which are read and executed by the processing circuit 110 to implement the associated functions and operations described in various embodiments of the present invention.

[0018] In this embodiment, the image source 120 may be, for example, a computer host, an imaging device, or a related image data providing device, but the present invention is not limited thereto. The image source 120 may provide image data S1 of a three-dimensional image or a two-dimensional image to the processing circuit 110. In this embodiment, the switching signal source 130 may be, for example, a physical button provided on the display device, a virtual button on the display interface of the display device, or a functional circuit provided in the processing circuit 110. The switching signal source 130 may generate a switching signal S2 based on a user operation, a system operation, or automatic analysis of the image data S1 by the processing circuit 110, and the processing circuit 110 drives the display panel 140 to perform a two-dimensional display mode or a three-dimensional display mode.

[0019] In this embodiment, when the processing circuitry 110 drives the display panel 140 to perform a 3D display mode, the image data S1 acquired by the processing circuitry 110 from the image source 120 may be view data having a multi-viewpoint image. Alternatively, the image data S1 may be view data of a single-viewpoint image, which may be further generated as a multi-viewpoint image after certain image processing. Alternatively, the image data S1 may be formed by two-dimensional image data and corresponding depth data.

[0020] In this embodiment, when the processing circuitry 110 drives the display panel 140 to perform a two-dimensional display mode, the image data S1 acquired by the processing circuitry 110 from the image source 120 may be view data having a multi-viewpoint image, and the processing circuitry 110 may select one of the multi-viewpoint images to drive the display panel 140 through switching. Alternatively, the processing circuitry 110 may switch to render one of the multi-viewpoint images to drive the display panel 140. Alternatively, the image data S1 is view data of a single-viewpoint image. Alternatively, the image data S1 may be formed by two-dimensional image data and corresponding depth data, and the processing circuitry 110 may switch to simply select the two-dimensional image data to drive the display panel 140.

[0021] FIG. 2 is a flow diagram of a switching method according to one embodiment of the present invention. Referring to FIGS. 1 and 2, the display system 100 may perform the following steps S110 to S140. In step S110, the image source 120 may provide image data S1 to the processing circuit 110. In step S120, the switching signal source 130 may provide a switching signal S2 to the processing circuit 110. In step S130, the processing circuit 110 may drive the display panel 140 to display a three-dimensional image or a two-dimensional image based on the switching signal S2. In step S140, when the processing circuit 110 drives the display panel 140 to display a two-dimensional image based on the switching signal S2, the processing circuit 110 may switch the luminance of a first pixel in the display panel 140 to a second luminance. In this regard, the second luminance may be determined based on a plurality of luminance values ​​in the image data S1 of a plurality of pixels of the same color adjacent to the first pixel and a weight value of the correction algorithm 111.

[0022] Therefore, in processing the display panel 140 to display a two-dimensional image, the processing circuit 110 may correct the image data S1 to generate corrected image data, and drive the display panel 140 based on the corrected image data. In this way, the brightness of the pixels of the display panel 140 can be effectively adjusted, and the display panel 140 can display a two-dimensional image with good image resolution.

[0026] FIG. 6A is a schematic diagram illustrating the display of a displayed 3D image according to one embodiment of the present invention. FIG. 6B is a schematic diagram of a display image corresponding to the 3D image according to one embodiment of the present invention. Referring to FIGS. 6A and 6B, FIGS. 6A and 6B are schematic diagrams of an actual display image displayed by a display panel according to one embodiment of the present invention. Referring to FIGS. 1 and 6A, as an example, image data S1 is acquired as image data for the 3D display image. The processing circuit 110 may perform a display operation for the 3D display image. In this embodiment, the processing circuit 110 may combine the result data of each light projection path to generate the actual display image 600 (the actual result of displaying the 3D image on the flat display screen). For example, as shown in FIG. 6A, it can be seen that, from the multiple light projection paths between the 3D image 600 and the display panel 140, the stereoscopic object image 601 and the stereoscopic object image 602 in the 3D image 600 may be displayed at different corresponding positions in the actual display image 610. Referring to FIGS. 1 and 6B, a microlens is used as an example of a light projection path passing through five different viewing angles. The display result of a plurality of pixels at the first viewing angle V1 of each microlens in the display panel 140 may be the display result of a sub-image 611. Similarly, the display result of a plurality of pixels at the second to fifth viewing angles V2 to V5 of each microlens in the display panel 140 may be the display result of sub-images 612 to 615. As a result, after the sub-images 611 to 615 are superimposed, the display panel 140 can display an actual display image 610 as shown in FIG. 6B . Therefore, a viewer can see a stereoscopic display image including a stereoscopic object image 601 and a stereoscopic object image 602 through the actual display image 610 displayed on the display panel 140. That is, the two-dimensional actual display image 610 appears to the human eye as a three-dimensional image including the stereoscopic object image 601 and the stereoscopic object image 602.

[0027] FIG. 7A is a schematic diagram illustrating a display of a two-dimensional image according to an embodiment of the present invention. FIG. 7B is a schematic diagram of a display image corresponding to the two-dimensional image according to an embodiment of the present invention. Referring to FIGS. 7A and 7B, FIGS. 7A and 7B are schematic diagrams of an actual display image displayed by a display panel according to an embodiment of the present invention. Referring to FIGS. 1 and 7A, image data S1 is acquired as image data of a two-dimensional display image, as an example. The processing circuit 110 may adjust the image data S1 of the two-dimensional display image based on the switching signal S2 to perform a display operation of the two-dimensional display image.

[0028] In this embodiment, the processing circuit 110 enables the display panel 500 to display an actual display image 710 (the actual result of displaying a two-dimensional image on a flat display screen) based on the corrected image data. For example, as shown in FIG. 7A , a two-dimensional object image 701 and a two-dimensional object image 702 in the two-dimensional image 700 may be displayed at different corresponding positions in the actual display image 710. Referring to FIGS. 1 and 7B , the display panel 140 can display the actual display image 710 as shown in FIG. 7B . The display result of the display panel 140 may be the same as the display result of an image 711. The image 711 is the actual display image 710. Therefore, a viewer can view a two-dimensional display image including the two-dimensional object image 701 and the two-dimensional object image 702 through the actual display image 710 displayed by the display panel 140.

[0029] FIG. 8 is a schematic diagram of pixel brightness adjustment according to an embodiment of the present invention. Referring to FIGS. 1 and 8, a pixel array 800 (a portion of the array area) of a display panel 140 may include a plurality of red pixels (R), a plurality of green pixels (G), and a plurality of blue pixels (B). Taking displaying a two-dimensional image and adjusting the brightness of a pixel 802 (i.e., a green pixel (G)) as an example, this embodiment is as follows: When the processing circuit 110 drives the display panel 140 to display a two-dimensional image based on the switching signal S2, the processing circuit 110 may switch the first brightness of the pixel 802 in the pixel array 800 of the display panel 140 to a second brightness. In this regard, the second brightness of the pixel 802 may be determined based on a plurality of brightness values ​​in the image data S1 of two pixels 801 and 803 (both green pixels (G)) of the same color that are horizontally adjacent to the pixel 802, and a plurality of weight values ​​of the correction algorithm 111. In this embodiment, the processing circuit 110 may multiply the luminance values ​​(or grayscale values) of the pixels 801-803 by the corresponding weight values ​​and then add the results to obtain a new luminance value for the pixel 802. The correction algorithm 111 may, for example, store the weight values ​​in the form of the following matrix (1):

number

[0030] For example, pixels 801 to 803 may have luminance values ​​A, B, and C, respectively. Matrix (1) includes, for example, weight values ​​WA, WB, and WC. The sum of weight values ​​WA, WB, and WC is equal to 1. In one embodiment, weight value WB may be equal to or greater than weight values ​​WA and WC, but the present invention is not limited thereto. The magnitude of the weight value may be negatively correlated with the distance from pixel 802. Therefore, the luminance value (B') of pixel 802 after correction may be calculated as shown in the following equation (1).

number

[0031] However, in one embodiment of the present invention, the second luminance of pixel 802 may be determined based on a plurality of luminance values ​​in image data S1 of a plurality of pixels (not limited to two, for example, matrix (1) may be a 1×5 matrix or a 1×7 matrix) of the same color that are adjacent to pixel 802 in the horizontal direction, and a plurality of weight values ​​in correction algorithm 111. Alternatively, in another embodiment of the present invention, the second luminance of pixel 802 may be determined based on a plurality of luminance values ​​in image data S1 of a plurality of pixels (not limited to two) of the same color that are adjacent to pixel 802 in the vertical direction, and a plurality of weight values ​​in correction algorithm 111.

[0032] In addition, it should be noted that the luminance of each pixel (or sub-pixel) in the image 800 may be corrected based on a plurality of corresponding luminance values ​​in the original image data S1 and a plurality of corresponding weight values ​​having the same weight distribution as or a different weight distribution from the matrix (1), so that the two-dimensional image actually displayed by the display panel 140 viewed by the human eye can have a good display effect.

[0033] 9 is a schematic diagram of pixel brightness adjustment according to an embodiment of the present invention. Referring to FIGS. 1 and 9, a pixel array 900 (a portion of the array area) of a display panel 140 may include a plurality of red pixels (R), a plurality of green pixels (G), and a plurality of blue pixels (B). Taking displaying a two-dimensional image and adjusting the brightness of an image 905 (i.e., green pixels (G)) in the pixel array 900 of the display panel 140 as an example, this embodiment is as follows: When the processing circuit 110 drives the display panel 140 to display a two-dimensional image based on the switching signal S2, the processing circuit 110 may switch the first brightness of the pixel 905 in the pixel array 900 of the display panel 140 to a second brightness. In this regard, the second luminance of pixel 905 may be determined based on luminance values ​​in image data S1 of multiple pixels 901-904 and 906-909 (all green pixels (G)) of the same color that are adjacent to pixel 905 in a predetermined region 910, and multiple weight values ​​of correction algorithm 111. In this embodiment, processing circuit 110 may multiply the luminance values ​​(or grayscale values) of pixels 901-909 by the corresponding weight values ​​and then add the results to obtain a new luminance value of pixel 905. Correction algorithm 111 may, for example, store the multiple weight values ​​in the form of the following matrix (2):

number

[0034] For example, pixels 901 to 909 may have luminance values ​​A to I, respectively. Matrix (2) includes, for example, weight values ​​WA to WI. The sum of weight values ​​WA to WI is equal to 1. Weight value WE may be greater than weight values ​​WB and WH. Weight values ​​WB and WH may be greater than weight values ​​WA and WI. Weight values ​​WA and WI may be greater than weight values ​​WD and WF. Weight values ​​WD and WF may be greater than weight values ​​WC and WG. In this embodiment, the magnitude of the weight value may be negatively correlated with the distance from pixel 905. Therefore, the luminance value (E') of pixel 902 after correction may be calculated as shown in the following equation (2).

number

[0035] However, in one embodiment of the present invention, the predetermined area 910 may be a 5×5 or 7×7 range including multiple pixels of the same color, and the present invention is not limited to the illustration in FIG.

[0036] In addition, it should be noted that the luminance of each pixel (or sub-pixel) in the image 900 may be corrected based on the corresponding luminance value in the original image data S1 and the corresponding weight values ​​having the weight distribution of matrix (2) or different weight distributions, so that the two-dimensional image actually displayed by the display panel 140 viewed by the human eye can have a good display effect.

[0037] FIG. 10 is a schematic diagram of pixel brightness adjustment according to one embodiment of the present invention. Referring to FIGS. 1 and 10, in this embodiment, a pixel array 1000 (a portion of the array area) of a display panel 140 may include a plurality of red pixels (R), a plurality of green pixels (G), and a plurality of blue pixels (B). In this embodiment, a lens array of the display panel 140 may include cylindrical lenses 1011-1014. An angle θ exists between an axis L1 of each of the cylindrical lenses 1011-1014 with no refractive power and a vertical axis L2 of the pixel array 1000. In this embodiment, the pixels of the pixel array 1000 may be divided into a plurality of cluster sets based on different light output angles corresponding to the cylindrical lenses 1011-1014.

[0038] Taking a two-dimensional image display corresponding to different light emission angles of cylindrical lenses 1011-1012 as an example, the positions of multiple pixels in the pixel array 1000 may correspond to multiple cluster sets 1001_1-1001_N, respectively, where N is a positive integer. In this embodiment, the processing circuit 110 may adjust the luminance of pixels belonging to the cluster set 1001_1 based on multiple luminance values ​​in the image data S1 of multiple adjacent pixels of the same color and multiple weight values ​​in the correction algorithm 111. Furthermore, the processing circuit 110 may adjust the luminance of pixels belonging to the cluster set 1001_2 based on different multiple luminance values ​​in the image data S1 of other adjacent pixels of the same color and multiple weight values ​​in the correction algorithm 111. In this regard, the weight distribution of the multiple weight values ​​used to correct the pixels belonging to the cluster set 1001_1 may be different from the weight distribution of the different multiple weight values ​​used to correct the pixels belonging to the cluster set 1001_2. In other words, the luminance correction method for different pixels of the pixel array 1000 may be determined based on the corresponding light output angle.

[0039] In summary, the switchable display system and switching method disclosed in the present invention can switch between displaying a three-dimensional image or a two-dimensional image. Furthermore, when displaying a two-dimensional image, the display system disclosed herein can automatically adjust image data to correct at least a portion of the pixels of the display panel, so that the two-dimensional image displayed by the display panel can have good display effect and display resolution.
