The processing circuit stores a correction algorithm and is configured to drive the display panel to display a three-dimensional image or a two-dimensional image according to the switching signal. When the processing circuit drives the display panel to display the two-dimensional image according to the switching signal, the processing circuit switches a first luminance of the first pixel to a second luminance.

Figure 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 the present embodiment, the display system 100 can realize a naked-eye stereoscopic display function and a two-dimensional display function, but the present disclosure is not limited thereto. In the present embodiment, the processing circuit 110 can receive image data S1 from the image source 120 and receive a switching signal S2 from the switching signal source 130. In the present embodiment, the switching signal S2 can be used to determine whether the processing circuit 110 drives the display panel 140 to perform a two-dimensional display mode or a three-dimensional display mode. The processing circuit 110 can determine whether to correct the image data S1 based on the switching signal S2, and can generate a corresponding driving signal S3 to the display panel 140 based on the uncorrected image data S1 or the corrected image data.

[0065] In the embodiment, the processing circuit 110 can be a display driving chip, and has a storage unit to store the correction algorithm 111. In an embodiment, the processing circuit 110 can include, for example, a central processing unit (CPU), a graphic processing unit (GPU), or other programmable general purpose or special purpose microprocessors (Microprocessor), digital signal processors (DSP), application specific integrated circuits (ASIC), programmable logic devices (PLD), other similar processing circuit or a combination of these devices.

The storage unit can store the correction algorithm 111 or related programs, modules, systems or image data for implementing the embodiments of the present disclosure, for reading and execution by the processing circuit 110 to implement the related functions and operations described in the embodiments of the present disclosure.

[0066] In the embodiment, the image source 120 can be, for example, a computer host, an image acquisition device or a related image data providing device, but the present disclosure is not limited thereto. The image source 120 can provide image data S1 of a three-dimensional image or a two-dimensional image to the processing circuit 110. In the embodiment, the switching signal source 130 can 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 can generate a switching signal S2 according to user operation, system operation or automatic analysis of the image data S1 by the processing circuit 110, so as to drive the display panel 140 to perform a two-dimensional display mode or a three-dimensional display mode.

[0067] In the embodiment, when the processing circuit 110 drives the display panel 140 to perform the three-dimensional display mode, the image data S1 obtained by the processing circuit 110 from the image source 120 can be view data of a perspective viewing picture with multiple viewing angles. Alternatively, the image data S1 can be view data of a perspective viewing picture with one viewing angle, and multiple viewing angles can be further generated through specific image processing. Alternatively, the image data S1 can be composed of two-dimensional image data and corresponding depth data.

[0068] In this embodiment, when the processing circuit 110 drives the display panel 140 to perform the two-dimensional display mode, the image data S1 obtained by the processing circuit 110 from the image source 120 can be view data of a plurality of perspective viewing pictures, and the processing circuit 110 can switch to select one of the plurality of perspective viewing pictures for driving the display panel 140.

Alternatively, the image data S1 itself is view data of a single perspective viewing picture. Alternatively, the image data S1 can be composed of two-dimensional image data and corresponding depth data, but the processing circuit 110 can switch to select only the two-dimensional image data for driving the display panel 140.

[0069] Figure 2 is a flowchart of a switching method of a display system according to an embodiment of the present disclosure. Referring to Figure 1 and Figure 2 , the display system 100 can perform the following steps S110-S140. In step S110, the image source 120 can provide image data S1 to the processing circuit 110. In step S120, the switching signal source 130 can provide a switching signal S2 to the processing circuit 110. In step S130, the processing circuit 110 can drive the display panel 140 to display a three-dimensional image or a two-dimensional image according to the switching signal S2. In step S140, when the processing circuit 110 drives the display panel 140 to display a two-dimensional image according to the switching signal S2, the processing circuit 110 can switch a first brightness of a first pixel in the display panel 140 to a second brightness. In this regard, the second brightness can be determined according to a plurality of brightness values of a plurality of same-color pixels adjacent to the first pixel in the image data S1 and a plurality of weight values of the correction algorithm 111.

[0070] Therefore, in the process of displaying a two-dimensional image by the display panel 140, the processing circuit 110 can correct the image data S1 to generate corrected image data, and drive the display panel 140 according to the corrected image data. In this way, the brightness effect of the pixels of the display panel 140 can be effectively adjusted, and thus the display panel 140 can display a two-dimensional image with good image resolution.

Figure 6B This is a schematic diagram of a display screen corresponding to a three-dimensional image according to an embodiment of the present disclosure. Figure 6A as well as Figure 6B , Figure 6A as well as Figure 6B is a schematic diagram of an actual display screen displayed by the display panel of the embodiment of the present disclosure. Figure 1 as well as Figure 6A , taking the image data S1 as the image data of a three-dimensional display image as an example. The processing circuit 110 can perform a display operation of the three-dimensional display image. In this embodiment, the processing circuit 110 can combine the synthetic data of each light projection path to generate an actual display screen 600 (the actual result of the three-dimensional image being displayed on the flat display screen). For example, Figure 6A As shown, from the multiple light projection paths between the 3D image 600 and the display panel 140, it can be seen that the 3D object image 601 and the 3D object image 602 in the 3D image 600 can be displayed at different corresponding positions of the actual display screen 610, for example. Figure 1 as well as Figure 6BFor example, a micro-lens can project light rays through five different viewing angles. The display results of the multiple pixels in the display panel 140 corresponding to the first viewing angle V1 for each micro-lens can be as shown in the sub-image 611. Similarly, the display results of the multiple pixels in the display panel 140 corresponding to the second to fifth viewing angles V2-V5 for each micro-lens can be as shown in the sub-images 612-615. As such, the sub-images 611-615 can be superimposed to form the actual display image 610 as shown in Figure 6B Thus, the viewer can view the stereoscopic display image having the stereoscopic object image 601 and the stereoscopic object image 602 through the actual display image 610 displayed by the display panel 140. That is, the two-dimensional actual display image 610 can be imaged in the human eye to form a three-dimensional image having the stereoscopic object image 601 and the stereoscopic object image 602.

[0075] Figure 7A is a display diagram of a two-dimensional image according to an embodiment of the disclosure. Figure 7B is a diagram of a display image corresponding to the two-dimensional image according to an embodiment of the disclosure. For reference Figure 7A and Figure 7B , Figure 7A and Figure 7B is a diagram of an actual display image displayed by a display panel according to an embodiment of the disclosure. For reference Figure 1 and Figure 7A For example, the image data S1 is the image data of a two-dimensional display image. The processing circuit 110 can adjust the image data S1 of the two-dimensional display image according to the switching signal S2 so as to perform a display operation of the two-dimensional display image.

[0076] In this embodiment, the processing circuit 110 can cause the display panel 500 to display the actual display image 710 (the actual result of displaying a two-dimensional image on a flat display screen) according to the corrected image data. For example, as shown in Figure 7A The two-dimensional object image 701 and the two-dimensional object image 702 in the two-dimensional image 700 can be displayed, for example, at different corresponding positions of the actual display image 710, respectively. For reference Figure 1 and Figure 7B The display panel 140 can display the result of the actual display image 710 as shown in Figure 7B The display result of the display panel 140 can be as shown in the image 711. The image 711 is the actual display image 710. Thus, the viewer can view the two-dimensional display image having 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.

[0077] Figure 8FIG. 1 is a schematic diagram of pixel brightness adjustment according to an embodiment of the present disclosure. Figure 1 as well as Figure 8 The pixel array 800 (a portion of the array) of the display panel 140 may include a plurality of red pixels (R), a plurality of green pixels (G), and a plurality of blue pixels (B). For example, when displaying a two-dimensional image, the brightness of pixel 802 (i.e., a green pixel (G)) in the pixel array 800 of the display panel 140 is adjusted. When the processing circuit 110 drives the display panel 140 to display the two-dimensional image according to the switching signal S2, the processing circuit 110 may switch the first brightness of pixel 802 in the pixel array 800 of the display panel 140 to a second brightness. The second brightness of pixel 802 may be determined based on the brightness values ​​of two same-colored pixels 801 and 803 (both green pixels (G)) adjacent to pixel 802 in the horizontal direction in the image data S1 and the weight values ​​of the correction algorithm 111. In this embodiment, the processing circuit 110 may multiply the brightness values ​​(or grayscale values) of pixels 801-803 by their corresponding weight values ​​and then add them together to obtain a new brightness value for pixel 802. The correction algorithm 111 may, for example, store the plurality of weight values ​​in the form of the following matrix (1).

[0078] [WA WB WC]............Matrix (1)

[0079] For example, pixels 801 to 803 may have brightness values ​​A, B, and C, respectively. Matrix (1) may include, for example, weight values ​​WA, weight values ​​WB, and weight values ​​WC. The sum of weight values ​​WA, weight values ​​WB, and weight values ​​WC is equal to 1. In one embodiment, weight value WB may be greater than or equal to weight value WA and weight value WC, but this is not disclosed herein. The magnitude of the weight value may be negatively correlated with the distance from pixel 802. Therefore, the brightness value (B') of pixel 802 after correction may be calculated as shown in the following equation (1).

[0080] B′=A*WA+B*WB+C*WC............Formula (1)

[0081] However, in one embodiment of the present disclosure, the second brightness of the pixel 802 may also be determined based on the brightness values ​​of a plurality of same-color pixels (not limited to two, and the matrix (1) may also be a 1×5 matrix or a 1×7 matrix, etc.) adjacent to the pixel 802 in the horizontal direction in the image data S1 and the weight values ​​of the correction algorithm 111. Alternatively, in another embodiment of the present disclosure, the second brightness of the pixel 802 may also be determined based on the brightness values ​​of a plurality of same-color pixels (not limited to two) adjacent to the pixel 802 in the vertical direction in the image data S1 and the weight values ​​of the correction algorithm 111.

[0082] In addition, it is worth noting that the brightness of each pixel (or sub-pixel) in the image 800 can be corrected based on the corresponding multiple brightness values ​​in the original image data S1 and the weight distribution that is the same as the above-mentioned matrix (1) or the corresponding multiple weight values ​​with different weight distributions, so that the two-dimensional image actually displayed by the display panel 140 seen by the human eye can have a good display effect.

[0083] Figure 9 FIG. 1 is a schematic diagram of pixel brightness adjustment according to an embodiment of the present disclosure. Figure 1 as well as Figure 9 , the pixel array 900 (partial array range) of the display panel 140 may include a plurality of red pixels (R), a plurality of green pixels (G), and a plurality of blue pixels (B). For example, when displaying a two-dimensional image, the brightness of a pixel 905 (i.e., a green pixel (G)) in the pixel array 900 of the display panel 140 is adjusted. When the processing circuit 110 drives the display panel 140 to display the two-dimensional image according to 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 brightness of the pixel 905 may be determined based on the brightness values ​​of a plurality of same-color pixels 901-904, 906-909 (all green pixels (G)) adjacent to the pixel 905 in the predetermined area 910 in the image data S1 and the weight values ​​of the correction algorithm 111. In this embodiment, the processing circuit 110 may multiply the brightness values ​​(or grayscale values) of pixels 901-909 by the corresponding weight values ​​and then add them together to obtain a new brightness value for pixel 905. The correction algorithm 111 may, for example, store the plurality of weight values ​​in the form of the following matrix (2).

[0084]

[0085] For example, pixels 901 to 909 may have brightness values ​​A to I, respectively. Matrix (2) may include, 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 value WB and weight value WH. Weight value WB and weight value WH may be greater than weight value WA and weight value WI. Weight value WA and weight value WI may be greater than weight value WD and weight value WF. Weight value WD and weight value WF may be greater than weight value WC and weight value WG. In one embodiment, the magnitude of the weight value may be negatively correlated with the distance from pixel 905. Therefore, the brightness value (E') of pixel 902 after correction may be calculated as shown in the following formula (2).

[0086] E′=A*WA+B*WB+C*WC+D*WD+E*WE+F*WF+G*WG+H*WH+I*WI......Formula (2)

[0087] However, in one embodiment of the present disclosure, the predetermined area 910 may also include a range of 5×5 or 7×7 pixels of the same color, and is not limited to Figure 9 shown.

[0088] In addition, it is worth noting that the brightness of each pixel (or sub-pixel) in the image 900 can be corrected based on the corresponding multiple brightness values ​​in the original image data S1 and the weight distribution that is the same as the above-mentioned matrix (2) or the corresponding multiple weight values ​​with different weight distributions, so that the two-dimensional image actually displayed by the display panel 140 seen by the human eye can have a good display effect.

[0089] Figure 10 FIG. 1 is a schematic diagram of pixel brightness adjustment according to an embodiment of the present disclosure. Figure 1 as well as Figure 10 In this embodiment, the pixel array 1000 (partial array range) of the 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, the lens array of the display panel 140 may include lenticular lenses 1011-1014. An angle θ is formed between the zero-power axes L1 of the lenticular lenses 1011-1014 and the vertical axis L2 of the pixel array 1000. In this embodiment, the plurality of pixels of the pixel array 1000 may be divided into a plurality of groups according to the different light emission angles corresponding to the lenticular lenses 1011-1014.

[0090] Taking the display of a two-dimensional image and the different light emission angles of lenticular lenses 1011 and 1012 as an example, a portion of the multiple pixels of pixel array 1000 may correspond to multiple groups 1001_1 to 1001_N, where N is a positive integer. In this embodiment, processing circuit 110 may perform brightness adjustment on pixels belonging to group 1001_1, determining the brightness based on the brightness values ​​of multiple adjacent same-color pixels in image data S1 and multiple weight values ​​in correction algorithm 111. Furthermore, processing circuit 110 may perform brightness adjustment on pixels belonging to group 1001_2, determining the brightness based on another brightness value of another adjacent same-color pixel in image data S1 and another weight value in correction algorithm 111. Therefore, the weight distribution of the multiple weight values ​​used to correct the pixels belonging to group 1001_1 may be different from the weight distribution of the other weight values ​​used to correct the pixels belonging to group 1001_2. In other words, the brightness correction method for different pixels in pixel array 1000 can be determined based on the corresponding light emission angles.

[0091] In summary, the switchable display system and the switching method thereof can switch to display a three-dimensional image or a two-dimensional image. When displaying a two-dimensional image, the display system can automatically adjust the image data to correct the brightness of 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.
