Display device and method of operating same

The present invention relates to the field of display devices, and more particularly to a display device and method of operation thereof.

The autosterescopic three-dimensional image display apparatus allows the user to see the advantages of the three-dimensional image without the need for the three-dimensional stereoscopic glasses, and becomes a three-dimensional image display product developed by various display device manufacturers.

However, the naked eye three-dimensional image display device also has its disadvantages, which are illustrated in FIGS. 1 to 4. FIG. 1 is a schematic diagram of a naked-eye three-dimensional image display device and a view angle of the three-dimensional image displayed thereon. In FIG. 1, reference numeral 100 denotes the naked-eye three-dimensional image display device, and the naked-eye three-dimensional image display device 100 is used to generate a three-dimensional image having four different viewing angles. In addition, the reference numeral 102 indicates a display surface of the naked eye three-dimensional image display device 100, the indications 104, 106, and 108 respectively indicate a certain three angular ranges in front of the display surface 102, and the indications V1 to V4 respectively indicate four of the displayed three-dimensional images. The images of different viewing angles are sequentially the image of the first view, the image of the second view, the image of the third view and the image of the fourth view. FIG. 2 is a schematic diagram of images of four different viewing angles shown in FIG. 1. In FIG. 2, the indications V1 to V4 sequentially represent the images of the above four different viewing angles.

Referring to FIG. 1 and FIG. 2 together, in any angular range in front of the display surface 102 of the naked-eye three-dimensional image display device 100, the user is at any angle. In the range, you will see two images of different perspectives. Therefore, the user's brain will form a stereoscopic image according to the images of two different viewing angles seen by the user. Taking the user in the angle range 104 as an example, the user's left eye will see the image of the first view (ie, the image indicated by V1), and the user's right eye will see the image of the second view ( That is, the image shown by V2 is indicated). The same is true for users in other angle ranges. When the user's left eye sees the image with the smaller angle of view, and the user's right eye sees the image with the larger angle of view, the user's left eye system sees the angle of view that would otherwise be seen by the left eye. The image of the user's right eye is the image of the viewing angle that is supposed to be seen by the right eye, so that the user's brain can form a correct stereoscopic image. At this time, the angle range of the user is said to be a sweet zone.

However, when the user is in the range of angles 106 or 108, the user's left eye will see the image with the larger number of views, and the user's right eye will see the image with the smaller number of views, because of the use at this time. The left eye of the person sees an image of the angle of view originally intended to be seen by the right eye, and the right eye of the user sees an image of the angle of view originally intended to be seen by the left eye, so that the user's brain cannot form a correct stereoscopic image. At this time, the angle range in which the user is said is a dead zone. In Fig. 1, each of the areas formed by the oblique lines is a dead zone. Each dead zone can determine the degree of visual difference according to the difference between the numbers of the two viewing angles seen by the user, and the degree of visual difference determines the visual comfort of the user. FIG. 3 is the degree of visual difference when the number difference of the angle of view is 3, and FIG. 4 is the degree of visual difference when the number difference of the angle of view is 1. As can be seen from FIG. 3 and FIG. 4, the higher the degree of visual difference, the more uncomfortable the user is visually.

Please refer to Figure 1 again. In addition to the dead zone, another factor that determines the user's visual comfort is the transition zone between the sweet zone and the dead zone (indicated by four triangles in Figure 1). The difference between the degree of visual difference between the sweet spot and the visual difference of the dead zone also determines the visual comfort of the user. The greater the difference between the visual difference between the sweet zone and the visual difference of the dead zone, the more visually the user is uncomfortable. suitable. Generally speaking, this effect is a jump effect. The larger the jump effect, the greater the difference between the degree of visual difference between the sweet spot and the visual difference of the dead zone.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a display device in which the jump effect is relatively small and the degree of visual difference in the dead zone can be adjusted, thereby improving the visual comfort of the user.

The display device includes a display panel, and the operation method includes the steps of: receiving image data of at least one two-dimensional image; and generating two-dimensional images of different viewing angles according to the image data of the received two-dimensional image. Image data; sequentially arranging the received two-dimensional images according to a cyclic sequence formed by a predetermined number of columns, and in the preset number of columns Each adjacent two numbers represents two adjacent viewing angles; the two-dimensional image of the viewing angle corresponding to at least one of the preset number columns is replaced by a mixed image of two-dimensional images including at least two different viewing angles, And synthesizing the image data of the three-dimensional image, wherein the image data of each mixed image comprises part of the image data of the two-dimensional image having the angle of view corresponding to at least two of the preset series; and the image according to the three-dimensional image The data is used to control the display panel to display the above three-dimensional image.

The invention further provides a display device comprising a display panel and a display panel control module. The display panel control module is electrically connected to the display panel. The display panel control module is configured to receive image data of at least one two-dimensional image, and the display panel control module further generates image data of the two-dimensional image of different viewing angles according to the image data of the received two-dimensional image, and according to The received two-dimensional image is sequentially arranged by a cyclic sequence formed by a predetermined sequence, and each adjacent two numbers in the preset sequence represents two adjacent viewing angles. In addition, the display panel control module further replaces the two-dimensional image of the viewing angle corresponding to at least one of the preset number columns with a mixed image of the two-dimensional image including at least two different viewing angles, and synthesizes a three-dimensional image accordingly. The image data of the image is controlled by the display panel to display the three-dimensional image according to the image data of the three-dimensional image. The interaction of a portion of the image data of each of the mixed images and a portion of the image data of at least one of the two adjacent images temporally adjacent thereto causes the three-dimensional image to visually present a flat region.

The present invention further proposes an operation method corresponding to the above-described other display device.

In addition, the display panel control module replaces the two-dimensional image of the viewing angle corresponding to at least one of the preset series with a mixed image of the two-dimensional image including at least two different viewing angles, and synthesizes the three-dimensional image accordingly. The image data is used to control the display panel to display the three-dimensional image according to the image data of the three-dimensional image, wherein the image data of each mixed image includes a partial image data of the two-dimensional image with the angle of view corresponding to at least two numbers in the preset sequence. Since the image data of each mixed image contains part of the image data of the two-dimensional image with the angle of view corresponding to at least two numbers in the preset sequence, the jumping effect can be slowed down. In addition, the degree of visual difference in the dead zone can be further reduced by mixing the image data of the appropriate two-dimensional image.

In another aspect, each of the image data of each mixed image used by each display panel control module of the present invention and a portion of the image data of at least one of the two adjacent images temporally adjacent to each other interact with each other.

For convenience of comparison with the prior art, the following embodiments will also be assumed to be exemplified by the use of the display devices of the present invention for generating three-dimensional images having four different viewing angles, but the invention is not limited thereto.

In addition, the present invention can solve the general view as shown in FIG. In addition to the problem of dead zone and jumping effect in the naked-eye three-dimensional image display device of the angular sequential arrangement mode, it can also be applied to other naked-eye three-dimensional image display devices arranged in different viewing angles, for example, in another application. A naked-eye three-dimensional image display device with a soft dead zone view sequential arrangement method, because the same problem occurs in such a naked-eye three-dimensional image display device. FIG. 5 is a schematic diagram of another naked eye 3D image display device and a view angle of the displayed 3D image. In Fig. 5, each of the areas formed by the oblique lines is also a dead zone, and each transition area is also indicated by a triangle. Next, various embodiments of the present invention will be described.

6 is a schematic diagram of a display device in accordance with an embodiment of the present invention. Referring to FIG. 6 , the display device 600 includes a display panel control module 610 and a display panel 620 . The display panel control module 610 is electrically connected to the display panel 620 . In this example, the display panel control module 610 further includes an image data processing device 612, a timing control circuit 614, a data driving circuit 616, and a scan driving circuit 618. The data driving circuit 616 and the scan driving circuit 618 are electrically connected to each other. The panel 620, the timing control circuit 614 is electrically connected to the data driving circuit 616 and the scan driving circuit 618, and the image data processing device 612 is electrically connected to the timing control circuit 614. In this example, the image data processing device 612 further includes a video content generating circuit 612-1, a data reforming circuit 612-2, and a video material supply circuit 612-3.

The image content generating circuit 612-1 is configured to receive the image data IN of the two-dimensional image, and generate image data of the two-dimensional image of different viewing angles according to the image data of the received two-dimensional image. It is assumed that the image content generating circuit 612-1 receives only the image data of one two-dimensional image. Since the two-dimensional image has only one viewing angle, the image content generating circuit 612-1 generates the other three according to the image data of the two-dimensional image. Image data of two-dimensional images of different viewing angles (ie, image data of two-dimensional images required by a naked-eye display device arranged in a general viewing order), or image data of two-dimensional images to generate two other different viewing angles The image data of the two-dimensional image (that is, in the order of the slow dead zone view) The naked eye displays the image data of the two-dimensional image required by the device, so that the subsequent circuit can synthesize the image data of the three-dimensional image with four different viewing angles. After the image data of each two-dimensional image required by the display device 600 is generated, the image content generating circuit 612-1 outputs the image data of each of the two-dimensional images.

The data reforming circuit 612-2 is configured to receive the image data of the two-dimensional image output by the image content generating circuit 612-1, and to sequentially arrange the received data according to a cyclic sequence formed by a predetermined number of columns. In a two-dimensional image, each adjacent two digits in the predetermined sequence represents two adjacent viewing angles. Assuming that the display device 600 is a display device in a general view order, the preset sequence may be a sequence consisting of 1, 2, 3, and 4 in sequence, and thus the cycle sequence formed by the preset number of columns It is 1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4, 1... It can be seen from the above that each adjacent two digits in the preset sequence represents two adjacent viewing angles. Further, as can be seen from the above, the above-described cyclic sequence is one cycle for every four numbers. The data reforming circuit 612-2 sequentially arranges the two-dimensional images of the angle of view corresponding to each of the numbers in accordance with each of the numbers in the above-mentioned cyclic sequence.

Next, the data reforming circuit 612-2 further replaces the two-dimensional image of the viewing angle corresponding to at least one of the preset number columns with a mixed image of the two-dimensional image including at least two different viewing angles, as shown in FIG. 7 to 9 to illustrate. Figure 7 shows one of the mixed images and is used to illustrate one of the alternatives. In FIG. 7, the diagram above the dashed line 702 represents a two-dimensional image ordering method in which one of the two-dimensional images is replaced by a mixed image 704, which is sorted according to the above-mentioned cyclic sequence. The mixed image 704 is a partial image data of a two-dimensional image corresponding to the two numbers 4 and 3 in the preset sequence, and the data amount is half of each. That is to say, the mixed image 704 is formed by combining half of the image data of the two-dimensional image of the third viewing angle and half of the image data of the two-dimensional image of the fourth viewing angle. In a preferred hybrid mode, the image data of each pixel in the mixed image 704 (ie, the image data represented by any number in the figure) is taken from the original two-dimensional image. Image data of pixels in the same row and column position in the image. The mixed image 704 is used to replace the original two-dimensional image of the third viewing angle.

In addition, in FIG. 7, each number in the drawing below the broken line 702 indicates the degree of visual difference of the image data of two corresponding pixels in the two adjacent two-dimensional images above the broken line 702. In addition, in the drawing below the dotted line 702, the lattice formed by the punctual pattern indicates that the displayed three-dimensional image is located in the sweet area; the lattice formed by the diagonal pattern indicates that the displayed three-dimensional image is visually presented. A flat area is formed, and the flat area does not exhibit a three-dimensional effect; in addition, the lattice formed by the cross line pattern indicates that the displayed three-dimensional image is located in the dead zone. From the pattern below the dotted line 702 in Fig. 7, it can be seen that when transitioning from the sweet zone to the dead zone, there is a flat zone for buffering, thereby smoothing the degree of visual difference between the sweet zone and the dead zone. The difference between them slows down the jump effect.

Figure 8 illustrates another hybrid image and illustrates another alternative. In FIG. 8, the diagram above the dashed line 802 represents a two-dimensional image ordering method in which one of the two-dimensional images is replaced by a mixed image 804, which is sorted according to the above-mentioned cyclic sequence. The mixed image 804 includes partial image data of the two-dimensional image corresponding to the three numbers of 2, 3, and 4 in the preset sequence, and the data amount is one-third. That is to say, the mixed image 804 is one-third of the image data of the two-dimensional image of the second viewing angle, one-third of the image data of the two-dimensional image of the third viewing angle, and the image of the two-dimensional image of the fourth viewing angle. One-third of the data is combined. The preferred mode of mixing is also the same as described above. The mixed image 804 is used to replace the original two-dimensional image of the fourth angle of view.

In addition, in FIG. 8, each number in the figure below the dotted line 802 represents the degree of visual difference of the image data of two corresponding pixels in the two adjacent two-dimensional images above the dotted line 802. In addition, in the drawing below the dotted line 802, the lattice formed by the punctual pattern indicates that the displayed three-dimensional image is located in the sweet area; the lattice formed by the diagonal pattern indicates that the displayed three-dimensional image is visually presented. Out of a flat area, and this The flat zone does not exhibit a three-dimensional effect; in addition, the lattice formed by the cross-hatching indicates that the displayed three-dimensional image is located in the dead zone. As can be seen from the pattern below the dotted line 802 of Fig. 8, when transitioning from the second sweet zone on the left to the rightmost dead zone, there will be a small dead zone, a small flat zone and a small sweet zone for buffering. Thus, the difference between the degree of visual difference between the left sweet spot and the rightmost dead zone is smoothed, thereby slowing down the jump effect. In addition, as can be seen from the pattern below the dotted line 802 of FIG. 8, the value of the visual difference degree of up to two-thirds of the rightmost dead zone becomes smaller, thereby slowing down the degree of visual difference of the dead zone.

Figure 9 shows three mixed images and is used to illustrate another alternative. In FIG. 9, the pattern above the dotted line 902 is sorted according to the above-mentioned cyclic sequence, and two-dimensional images of three three-dimensional images are replaced by three mixed images (labeled by 904, 906, and 908, respectively). Sort by. In addition, in FIG. 9, each number in the figure below the dotted line 902 indicates the degree of visual difference of the image data of two corresponding pixels in the two adjacent two-dimensional images above the dotted line 902. In addition, in the drawing below the dotted line 902, the lattice formed by the punctual pattern indicates that the displayed three-dimensional image is located in the sweet area; the lattice formed by the diagonal pattern indicates that the displayed three-dimensional image is visually presented. A flat area is formed, and the flat area does not exhibit a three-dimensional effect; in addition, the lattice formed by the cross line pattern indicates that the displayed three-dimensional image is located in the dead zone. The principle shown in FIG. 9 is similar to the principle shown in FIG. 7 and FIG. 8, and will not be described again here. From the figure below the dotted line 902 of Fig. 9, it is known that not only the jumping effect is slowed down, but also the degree of visual difference in the dead zone is slowed down.

Referring to FIG. 6 again, the data reforming circuit 612-2 replaces the two-dimensional image of the viewing angle corresponding to at least one of the preset number columns with a mixed image of the two-dimensional image including at least two different viewing angles. The image data of each 2D image is output. The image data supply circuit 612-3 is configured to receive the output of the data reforming circuit 612-2, and synthesize the image data of the three-dimensional image, that is, to synthesize three images having four different viewing angles. Image data of the dimensional image. The timing control circuit 614 is configured to control the display panel 620 to display the three-dimensional image through the data driving circuit 616 and the scan driving circuit 618 according to the image data of the three-dimensional image output by the data reforming circuit 612-2.

In addition, assuming that the display device 600 is a display device arranged in a slow dead zone view order, the preset sequence may be a sequence consisting of 1, 2, 3, and 2 in sequence, thus presetting the sequence The cycle sequence formed is 1, 2, 3, 2, 1, 2, 3, 2, 1, 2, 3, 2, 1... This pre-set number is only an example and is not intended to limit the invention. As can be seen from the above, each adjacent two digits in the preset sequence represents two adjacent viewing angles. Further, as can be seen from the above, the above-described cyclic sequence is one cycle for every four numbers. The data reforming circuit 612-2 sequentially arranges the two-dimensional images of the angle of view corresponding to each of the numbers in accordance with each of the numbers in the above-mentioned cyclic sequence.

Next, the data reforming circuit 612-2 further replaces the two-dimensional image of the viewing angle corresponding to at least one of the preset number columns with a mixed image of the two-dimensional image including at least two different viewing angles, as shown in FIG. 10 12 to illustrate. Figure 10 shows one of the mixed images and is used to illustrate one of the alternatives. In FIG. 10, the pattern above the dotted line 1002 represents a two-dimensional image sorting method in which one of the two-dimensional images is replaced by a mixed image 1004. In addition, in FIG. 10, each number in the figure below the dotted line 1002 indicates the degree of visual difference of the image data of two corresponding pixels in the two adjacent two-dimensional images above the dotted line 1002. In addition, in the drawing below the dotted line 1002, the lattice formed by the punctual pattern indicates that the displayed three-dimensional image is located in the sweet spot; the lattice formed by the diagonal pattern indicates that the displayed three-dimensional image is visually presented. A flat area is formed, and the flat area does not exhibit a three-dimensional effect; in addition, the lattice formed by the cross line pattern indicates that the displayed three-dimensional image is located in the dead zone. From the figure below the dotted line 1002 in Fig. 10, not only the jump effect is slowed down, but also the degree of visual difference in the dead zone is slowed down.

Figure 11 shows another hybrid image and is used to illustrate another Generation method. In FIG. 11, the diagram above the dashed line 1102 represents a two-dimensional image ordering method in which one of the two-dimensional images is replaced by a mixed image 1104, which is sorted according to the above-mentioned cyclic sequence. In addition, in FIG. 11, each number in the drawing below the broken line 1102 indicates the degree of visual difference of the image data of two corresponding pixels in the two adjacent two-dimensional images above the broken line 1102. In addition, in the drawing below the broken line 1102, the lattice formed by the punctual pattern indicates that the displayed three-dimensional image is located in the sweet area; the lattice formed by the diagonal pattern indicates that the displayed three-dimensional image is visually presented. A flat area is formed, and the flat area does not exhibit a three-dimensional effect; in addition, the lattice formed by the cross line pattern indicates that the displayed three-dimensional image is located in the dead zone. From the pattern below the dotted line 1102 of Fig. 11, it is known that not only the jumping effect is slowed down, but also the degree of visual difference in the dead zone is slowed down.

Figure 12 shows three mixed images and is used to illustrate another alternative. In FIG. 12, the pattern above the dotted line 1202 is sorted according to the above-mentioned cyclic sequence, and two-dimensional images of three three-dimensional images are replaced by three mixed images (labeled by 1204, 1206 and 1208, respectively). Sort by. In addition, in FIG. 12, each number in the figure below the dotted line 1202 indicates the degree of visual difference of the image data of two corresponding pixels in the two adjacent two-dimensional images above the dotted line 1202. In addition, in the drawing below the dotted line 1202, the lattice formed by the punctual pattern indicates that the displayed three-dimensional image is located in the sweet area; the lattice formed by the diagonal pattern indicates that the displayed three-dimensional image is visually presented. A flat area is formed, and the flat area does not exhibit a three-dimensional effect; in addition, the lattice formed by the cross line pattern indicates that the displayed three-dimensional image is located in the dead zone. It can be seen from the pattern below the dotted line 1202 of Fig. 12 that not only the jumping effect is slowed down, but also the degree of visual difference in the dead zone is slowed down.

FIG. 13 is a schematic diagram of a display device in accordance with another embodiment of the present invention. Referring to FIG. 13 , the display device 1300 includes a display panel control module 1310 and a display panel 1320 . The display panel control module 1310 is electrically connected to the display panel 1320 . In this example, the display panel control module 1310 further includes the image data processing device 1312.

The display device 1300 is different from the aforementioned display device 600 in that the display device 1300 includes a front end circuit 1312-1. The front end circuit 1312-1 is configured to receive image data IN of at least one two-dimensional image, and perform at least one of image scaling processing, screen update rate control processing, and image processing on the received two-dimensional image.
