Description

Stereoscopic display device and stereoscopic display method

The present invention relates to a display device and a display method, and in particular to a stereoscopic display device and a stereoscopic display method.

Currently, autosterescopy displays send left-eye images and right-eye images to the user's left eye and right eye respectively, so that the user's eyes can see three-dimensional images without the need for additional hardware (such as three-dimensional glasses).

However, the above method will cause overlapping images (or afterimages) to be seen at the edge of the image, which will cause users to feel tired or uncomfortable when viewing the image. Therefore, the current state of the above technology is a problem that the industry urgently needs to invest time in research and development and obtain a solution.

The content of the invention is intended to provide a simplified summary of the disclosure so that readers can have a basic understanding of the disclosure. This content of the invention is not a complete overview of the disclosure, and it is not intended to point out the important/key elements of the embodiments of the present case or to define the scope of the present case.

The three-dimensional display panel includes a plurality of visual areas. The plurality of visual areas are used to output a plurality of visual images. A portion of the plurality of visual areas constitutes a left eye block, and another portion of the plurality of visual areas constitutes a right eye block. The memory is used to store a plurality of instructions. The processor is used to execute the following steps according to the plurality of instructions in the memory: divide the left eye block into a first sub-block, a second sub-block and a third sub-block according to the plurality of first visual area numbers of the left eye block, and one of the eyes of the user corresponds to the second sub-block; output a first visual image through the first visual area of the first sub-block; output the first visual image through the second visual area of the second sub-block; output the second visual image through the third visual area of the second sub-block; and output the second visual image through the fourth visual area of the third sub-block. The first visual image differs from the second visual image by a first offset. The plurality of visual areas include the first visual area, the second visual area, the third visual area and the fourth visual area, and the plurality of visual images include the first visual image and the second visual image.

Another technical aspect of the present invention is a stereoscopic display method. The stereoscopic display method includes the following steps: using an eye tracker to divide a plurality of visual areas into a left eye block and a right eye block according to the user's eyes; dividing the left eye block into a first sub-block, a second sub-block and a third sub-block according to a plurality of first visual area numbers of the left eye block, and one of the eyes corresponds to the second sub-block; outputting a first visual image through the first visual area of the first sub-block; outputting a first visual image through the second visual area of the second sub-block; outputting a second visual image through the third visual area of the second sub-block; and outputting a second visual image through the fourth visual area of the third sub-block. The first visual image differs from the second visual image by a first offset. The plurality of viewing areas include a first viewing area, a second viewing area, a third viewing area, and a fourth viewing area, and the plurality of viewing images include a first viewing image and a second viewing image.

Therefore, according to the technical content of this case, the stereoscopic display device and the stereoscopic display method shown in the embodiment of this case can achieve the effect of making the user feel comfortable when viewing the stereoscopic image by adjusting the output between the display area and the display screen.

For example, the left eye block L1 in FIG. 1B may correspond to the left eye block L1A in FIG. 4 , but the present invention is not limited thereto.

Then, the memory 121 is used to store a plurality of instructions. The processor 122 is used to execute the following steps according to the plurality of instructions of the memory 121: divide the left eye block L1A into a first sub-block A1, a second sub-block A2 and a third sub-block A3 according to a plurality of first visual area numbers (e.g., visual area numbers 1 to 16) of the left eye block L1 or L1A, and one of the user's eyes (e.g., eye E1A) corresponds to the second sub-block A2; output an initial visual image (e.g., a visual image corresponding to visual signal number 2) through the initial visual area of the first sub-block A1 (e.g., a visual area corresponding to visual area number 1); output an initial visual image (e.g., a visual image corresponding to visual signal number 2) through the first visual area of the first sub-block A1 (e.g., a visual area corresponding to visual area number 1); The first visual image (e.g., the visual image corresponding to the visual signal number 8) is outputted through the second visual area of the second sub-block A2 (e.g., the visual area corresponding to the visual area number 4); the first visual image (e.g., the visual image corresponding to the visual signal number 8) is outputted through the second visual area of the second sub-block A2 (e.g., the visual area corresponding to the visual area number 8); the second visual image (e.g., the visual image corresponding to the visual signal number 11) is outputted through the third visual area of the second sub-block A2 (e.g., the visual area corresponding to the visual area number 11); and the second visual image (e.g., the visual image corresponding to the visual signal number 11) is outputted through the fourth visual area of the third sub-block A3 (e.g., the visual area corresponding to the visual area number 14).

Next, the initial image (e.g., the image corresponding to the image number 2) and the first image (e.g., the image corresponding to the image number 8) differ by an initial offset. The first image (e.g., the image corresponding to the image number 8) and the second image (e.g., the image corresponding to the image number 11) differ by a first offset.

For example, the initial visual image of FIG. 4 (e.g., the visual image corresponding to the visual signal number 2) may correspond to the image V11 of FIG. 2C, the first visual image of FIG. 4 (e.g., the visual image corresponding to the visual signal number 8) may correspond to the image V12 of FIG. 2C, the second visual image of FIG. 4 (e.g., the visual image corresponding to the visual signal number 11) may correspond to the image V13 of FIG. 2C, and the object B11 of the image V11 may have an initial angle G0 (for example: 0 degrees), object B12 in screen V12 may have an offset angle G1 (for example: 5 degrees), and object B13 in screen V13 may have an offset angle G2 (for example: 10 degrees). Therefore, the initial offset of Figure 4 may correspond to the offset g1 of Figure 2C (for example: 5 degrees), and the first offset of Figure 4 may correspond to the difference between the offset angle G2 and the offset angle G1 of Figure 2C (for example: 5 degrees), but the present case is not limited to this.

For example, the initial visual image of Figure 4 (e.g., the visual image corresponding to the visual signal number 2) may correspond to the screen V21 of Figure 2D, the first visual image of Figure 4 (e.g., the visual image corresponding to the visual signal number 8) may correspond to the screen V22 of Figure 2D, the second visual image of Figure 4 (e.g., the visual image corresponding to the visual signal number 11) may correspond to the screen V23 of Figure 2D, and the object B21 of the screen V21 may have an initial position X0 (e.g., X-axis is 0), object B22 in screen V22 may have position X1 (e.g., position 1 on the X-axis), and object B23 in screen V23 may have position X2 (e.g., position 2 on the X-axis). Therefore, the initial offset of FIG. 4 may correspond to the difference between position X1 and initial position X0 in FIG. 2D (e.g., 5 mm), and the first offset of FIG. 4 may correspond to the difference between position X2 and position X1 in FIG. 2D (e.g., 5 mm), but the present invention is not limited thereto.

The first number, the second number, the third number, and the fourth number are positive integers greater than or equal to 1, the first number is equal to the sum of the second number and the third number, and the sum of the second number and the third number is equal to the fourth number.

For example, the first viewing area may be the viewing area corresponding to viewing area numbers 1 to 6, and the first number may be 6. The second viewing area may be the viewing area corresponding to viewing area numbers 6 to 8, and the second number may be 3. The third viewing area may be the viewing area corresponding to viewing area numbers 9 to 11, and the third number may be 3.

FIG. 5 is a diagram showing a usage scenario of a stereoscopic display device according to an embodiment of the present invention. As shown in FIG. 5 , in some embodiments, the normal mode of FIG. 5 may correspond to the multi-view reverse mode of FIG. 3 , and the reverse mode of FIG. 5 may correspond to the multi-view reverse mode-2 of FIG. 3 .

For example, the correlation between the visual area number and the visual signal number in the normal mode (Normal mode) of Figure 5 can be similar to the correlation between the visual area number and the visual signal number in the multi-view reverse mode of Figure 3, and the reverse mode (Reverse mode) of Figure 5 can be similar to the correlation between the visual area number and the visual signal number in the multi-view reverse mode-2 of Figure 3. In order to simplify the content of the specification, it will not be repeated here, but the present case is not limited to this.

Please refer to FIG. 1A, FIG. 1B, FIG. 3 and FIG. 5 together. In one embodiment, the processor 122 (as shown in FIG. 1A) is further used to execute the following steps according to a plurality of instructions of the memory 121: according to a plurality of second visual area numbers (for example, visual area numbers 17 to 32) of the right eye block R1A, the right eye block R1A is divided into a fourth sub-block A4, a fifth sub-block A5 and a sixth sub-block A6, and the other eye of the user (for example, eye E2A) corresponds to the fifth sub-block A5; by outputting the fifth visual area of the fourth sub-block A4 (for example, the visual area corresponding to the visual area number 20) A third visual image (e.g., a visual image corresponding to visual signal number 24); outputting the third visual image (e.g., a visual image corresponding to visual signal number 24) through the sixth visual area of the fifth sub-block A5 (e.g., a visual area corresponding to visual area number 24); outputting the fourth visual image (e.g., a visual image corresponding to visual signal number 25) through the seventh visual area of the fifth sub-block A5 (e.g., a visual area corresponding to visual area number 25); and outputting the fourth visual image (e.g., a visual image corresponding to visual signal number 25) through the eighth visual area of the sixth sub-block A6 (e.g., a visual area corresponding to visual area number 29).

Next, the third visual image (eg, the visual image corresponding to the visual signal number 24) and the fourth visual image (eg, the visual image corresponding to the visual signal number 25) differ by a second offset.

The object B21 of the screen V21 can have an initial position X0 (for example, the position 0 on the X-axis), and the object B23 of the screen V23 can have a position X2 (for example, the position 2 on the X-axis). Therefore, the second offset of Figure 4 can correspond to the offset of Figure 2D (for example, the difference between the initial position X0 and the position X2, and the above difference can be 10 mm), but the present case is not limited to this.

Then, the plurality of viewing areas include a fifth viewing area (e.g., a viewing area corresponding to viewing area number 20), a sixth viewing area (e.g., a viewing area corresponding to viewing area number 24), a seventh viewing area (e.g., a viewing area corresponding to viewing area number 25), and an eighth viewing area (e.g., a viewing area corresponding to viewing area number 29), and the plurality of visual images include a third visual image (e.g., a visual image corresponding to visual signal number 24) and a fourth visual image (e.g., a visual image corresponding to visual signal number 25).
