[0004] A stereoscopic image display device can generate an image with a three-dimensional (3D) effect by presenting to a user an image or multiple images that simulate the way the user perceives depth in the real world. For example, a stereoscopic image display device can use binocular parallax between the left eye and the right eye to provide different images to the left eye and the right eye of the user so that the user can perceive the 3D effect.

[0035] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that a person skilled in the art can easily implement the present invention. The present invention can be implemented in various forms and is not limited to the embodiments described herein.

[0036] In order to clearly describe the present invention, parts irrelevant to the description may be omitted, and the same or similar elements are designated by the same reference numerals throughout the specification. Therefore, the above reference numerals may also be used in other drawings.

[0037] In addition, for the convenience of description, the size and thickness of each component shown in the drawings can be arbitrarily shown, so the present invention is not necessarily limited to the contents shown in the drawings. In the drawings, the thickness can be exaggerated to clearly express layers and regions.

[0038] Furthermore, in the description, the expression "same" may mean "substantially the same". That is, it may be sufficiently identical to allow a person of ordinary skill in the art to believe that it is the same. In other expressions, "substantially" may be omitted.

[0039] Figure 1 It is a diagram for explaining a lens array type stereoscopic image display device.

[0040] Reference Figure 1 The display device (or lens array type stereoscopic image display device) 10 may include a display panel DP and a lens array LSA.

[0041] The display panel DP may include sub-pixels SPX that can emit light to display an image. Different sub-pixels SPX may output light of different colors. In an embodiment, each of the sub-pixels SPX may output light of a first color (e.g., red), light of a second color (e.g., green), or light of a third color (e.g., blue). However, this is merely an example, and the color of light emitted from the sub-pixel SPX is not limited thereto. In addition, the number of colors is not limited thereto. Light of various colors for realizing a color gamut may be output. The display panel DP may include an organic light emitting display panel, a liquid crystal display panel, a quantum dot display panel, and the like.

[0042] The lens array LSA may be disposed on the display panel DP. The lens array LSA may include lenses LS that refract light incident from the sub-pixels SPX. For example, the lens array LSA may be implemented as a lenticular lens array, a micro lens array, or the like.

[0043] A light field display may be a 3D display device that implements a stereoscopic image. A light field display may implement a stereoscopic image by using a flat panel display and an optical element (e.g., a lens array LSA) to form a light field expressed as a vector distribution (intensity, direction) of light in space. Because the viewer can perceive the depth and side of an object in a stereoscopic image, a light field display may implement a natural stereoscopic image. A light field display may be a display technology used in various ways by merging with AR (augmented reality) technology and the like.

[0044] The light field can be implemented in a variety of ways. For example, a light field can be formed by a method of creating a multi-directional light field using multiple projectors, a method of controlling the direction of light using a diffraction grating, a method of adjusting the direction and intensity (illuminance) of light according to a combination of individual pixels using two or more panels, a method of controlling the direction of light using a pinhole or a barrier, a method of controlling the direction of light refraction through a lens array, and the like.

[0045] In an embodiment, Figure 1 As shown in , the lens array type stereoscopic image display device 10 can display a stereoscopic image (3D image) by forming a light field.

[0046] A plurality of sub-pixels SPX may be arranged to correspond to each lens LS. Light emitted from the sub-pixel SPX may be refracted by the corresponding lens LS and travel in a specific direction. Light emitted from each of the sub-pixels SPX may be refracted in different directions by the lens LS to form a light field expressed by light intensity and direction. When a viewer views the display device 10 within the light field formed as described above, the viewer may perceive a three-dimensional effect of the corresponding image.

[0047] Image information according to the viewer's viewpoint within the light field can be defined and processed in units of voxels. A voxel can be understood as graphic information that defines a predetermined point (or pixel) in 3D space.

[0048] The resolution of a 2D image may be determined by the number (e.g., density) of pixels in the same area. For example, when the number of pixels (or sub-pixels SPX) in the same area increases, the resolution of the 2D image may increase. That is, a display panel DP having a high pixel density may display a high-resolution image. Similarly, when the number of voxels at the same viewpoint through the lens array LSA increases, the resolution of a stereoscopic image may increase.

[0049] Figure 2It is a diagram for explaining the relationship between the lens array and the display panel.

[0050] The display panel DP may include sub-pixels SPX arranged in a first direction DR1 and a second direction DR2 perpendicular to the first direction DR1. The sub-pixels SPX may include light emitting surfaces in a third direction DR3 perpendicular to the first direction DR1 and the second direction DR2. The third direction DR3 may be perpendicular to a plane formed by the first direction DR1 and the second direction DR2.

[0051] The lens array LSA may include a plurality of lenses LS1, LS2, ... The lenses LS1, LS2, ... may overlap with the sub-pixel SPX in the third direction DR3. The lenses LS1, LS2, ... may have long sides intersecting with the sub-pixel SPX. The lenses LS1, LS2, ... may be arranged so that their long sides have an angle SAG greater than 0 degrees relative to the second direction DR2. For example, the lenses LS1, LS2, ... may be inclined biconvex lenses. For example, the first lens LS1 may include a first long side LS1s1 and a second long side LS1s2 parallel to each other. In addition, the second lens LS2 may include a first long side LS2s1 and a second long side LS2s2 parallel to each other. The lenses LS1, LS2, ... may be arranged in the first direction DR1. However, in an embodiment, the angle SAG may be 0 degrees. When the angle SAG is 0 degrees, the long sides LS1s1, LS1s2, LS2s1, LS2s2, ... of the lenses LS1, LS2, ... may extend in the second direction DR2.

[0052] The lower surface (surface facing the sub-pixel SPX) of each of the lenses LS1, LS2, ... may be divided into a plurality of viewpoint areas V1 to V39. The plurality of viewpoint areas V1 to V39 may not be physically divided but may be virtual areas, and may be defined in various ways according to the resolution of the display panel DP, the specifications of the lenses LS1, LS2, ..., the number of viewpoints to be provided to the viewer, etc. Each of the lenses LS1, LS2, ... may distribute light corresponding to each of the viewpoint areas V1 to V39 in different directions (different viewpoints), so that the viewer may visually recognize a multi-view image in which the image changes according to the position.

[0053] The sub-pixel SPX may overlap one or more of the plurality of viewpoint regions V1 to V39. For example, the sub-pixel SPX may be positioned to correspond to the plurality of viewpoint regions V1 to V39. The sub-pixels SPX corresponding to the same viewpoint region may display an image of the same viewpoint. For example, due to Figure 2 There are 39 viewpoint areas V1 to V39, so the display panel DP can display 39 images simultaneously.

[0054] The display device 10 can display a stereoscopic image by displaying a left eye image using a sub-pixel SPX overlapping with the viewpoint areas V1 to V20 and displaying a right eye image using a sub-pixel SPX overlapping with the viewpoint areas V21 to V39. In this case, the viewer can be positioned so that the left eye image is visually recognized by the left eye and the right eye image is visually recognized by the right eye.

[0055] Sub-pixels SPX can be used in various formats such as RGB stripes, diamond PENTILE ® , S-stripes, Real RGB or regular PENTILE ® Various structural arrangements such as the following:

[0056] Figure 3 It is a diagram for explaining a display panel according to an embodiment of the present invention.

[0057] Reference Figure 3 , the display panel DPa according to an embodiment of the present utility model may include a plurality of pixels PX1, PX2, PX3, .... Each of the plurality of pixels PX1, PX2, PX3, ... may include a first sub-pixel (e.g., indicated by pattern C1), a second sub-pixel (e.g., indicated by pattern C2), and a third sub-pixel (e.g., indicated by pattern C3). The positions and shapes of the pixels PX1, PX2, PX3, ..., the first sub-pixels R11 to R43, the second sub-pixels G11 to G43, and the third sub-pixels B11 to B43 are described based on the light emitting surface of the light emitting element. That is, the pixel circuit may be arranged independently of the pixel or sub-pixel.

[0058] The pixels PX1, PX2, PX3, ... may be arranged in a first direction DR1 and a second direction DR2 perpendicular to the first direction DR1. The pixels PX1, PX2, PX3, ... may include a light emitting surface in a third direction DR3 perpendicular to the first and second directions DR1 and DR2.

[0059] The lens may overlap with the pixels PX1, PX2, PX3, ... The lens may overlap with the pixels PX1, PX2, PX3, ... substantially in the third direction DR3. The lens may overlap with the pixels PX1, PX2, PX3, ... and may be arranged such that their long sides have a first angle SAG with respect to the second direction DR2. The shape of the lens may refer to Figure 2 .

[0060] Each of the pixels PX1, PX2, PX3, ... may include a first sub-pixel emitting light of a first color, a second sub-pixel emitting light of a second color, and a third sub-pixel emitting light of a third color. The first color may be one of red, green, and blue. The second color may be one of red, green, and blue other than the first color. The third color may be one of red, green, and blue other than the first color and the second color. In an embodiment, additional and / or other colors of light may be emitted. For example, magenta, cyan, and yellow may be used instead of red, green, and blue as the first to third colors.

[0061] The sub-pixels R11 to R43, G11 to G43, B11 to B43, ... may be arranged in an S-striped structure. For example, referring to the first pixel PX1, the length of the third sub-pixel B11 in the second direction DR2 may be greater than the length of the first sub-pixel R11 in the second direction DR2 and the length of the second sub-pixel G11 in the second direction DR2. The third sub-pixel B11 may be positioned from the first sub-pixel R11 and the second sub-pixel G11 in the first direction DR1. According to an embodiment, the length of the third sub-pixel B11 in the second direction DR2 may be greater than the sum of the length of the first sub-pixel R11 in the second direction DR2 and the length of the second sub-pixel G11 in the second direction DR2.

[0062] With reference to the first direction DR1 as a row direction and the second direction DR2 as a column direction, the pixels PX1, PX2, PX3, ... may be arranged in a matrix form. The first sub-pixels R11 to R43, ... may be arranged in a matrix form. The second sub-pixels G11 to G43, ... may be arranged in a matrix form. The third sub-pixels B11 to B43, ... may be arranged in a matrix form.

[0063] The first reference line RFL1 may be an imaginary reference line parallel to the long side of the lens. Therefore, the first reference line RFL1 may have a first angle SAG relative to the second direction DR2. The first reference line RFL1 may be positioned to pass through a vertex (e.g., a lower left vertex) of a first subpixel R11 of the first pixel PX1. The first subpixel R11 may be a subpixel at a position where crosstalk with other viewpoints is reduced or minimized (or crosstalk with other viewpoints does not occur).

[0064] In this case, the vertex of the first subpixel constituting the same viewpoint as the first subpixel R11 may be positioned on the first reference line RFL1. For example, since the vertex of the first subpixel R43 overlaps the first reference line RFL1, the first subpixel R11 of the first pixel PX1 and the first subpixel R43 of the third pixel PX3 may implement an image of the same viewpoint with reduced or minimized crosstalk.

[0065] The vertex of the first sub-pixel R32 of the second pixel PX2 may not overlap with the first reference line RFL1. The first reference line RFL1 may be positioned to intersect with the light emitting surface of the first sub-pixel R32. Therefore, if the first sub-pixel R32 displays an image of the same viewpoint as the first sub-pixels R11 and R43, crosstalk with other viewpoints may be increased. For example, if the first sub-pixel R32 displays an image of the same viewpoint as the first sub-pixels R11 and R43, crosstalk with other viewpoints may occur significantly.

[0066] The second reference line RFL2 may be an imaginary reference line parallel to the long side of the lens. Therefore, the second reference line RFL2 may have a first angle SAG relative to the second direction DR2. The second reference line RFL2 may be positioned to pass through a vertex (e.g., a lower left vertex) of the second subpixel G11 of the first pixel PX1. The second subpixel G11 may be a subpixel at a position where crosstalk with other viewpoints is reduced or minimized (or crosstalk with other viewpoints does not occur).

[0067] In this case, the vertices of the second subpixel constituting the same viewpoint as the second subpixel G11 can be positioned on the second reference line RFL2. For example, since the vertices of the second subpixel G43 overlap the second reference line RFL2, the second subpixel G11 of the first pixel PX1 and the second subpixel G43 of the third pixel PX3 can realize an image of the same viewpoint with reduced or minimized crosstalk.

[0068] The vertex of the second sub-pixel G32 of the second pixel PX2 may not overlap with the second reference line RFL2. The second reference line RFL2 may be positioned to intersect with the light emitting surface of the second sub-pixel G32. Therefore, if the second sub-pixel G32 displays an image of the same viewpoint as the second sub-pixels G11 and G43, crosstalk with other viewpoints may be increased. For example, if the second sub-pixel G32 displays an image of the same viewpoint as the second sub-pixels G11 and G43, crosstalk with other viewpoints may occur significantly.

[0069] Figure 4 and Figure 5 is a diagram for explaining a display panel according to an embodiment of the present disclosure.

[0070] Reference Figure 4 , the display panel DPb may include a plurality of pixels PX1, PX2, PX3, .... Each of the plurality of pixels PX1, PX2, PX3, ... may include an arrangement of sub-pixels. In the display panel DPb, the arrangement of sub-pixels in different pixels may be different. For example, the positions of the first sub-pixels R11 to R43, ... and the second sub-pixels G11 to G43, ... may be different relative to the third sub-pixels B11 to B43, ....

[0071] In the display panel DPb, the first subpixel R11 of the first pixel PX1 and the first subpixel R32 of the second pixel PX2 may be aligned along an imaginary first reference line RFL1 parallel to the long side of the lens. For example, the first subpixel R11 of the first pixel PX1 and the first subpixel R32 of the second pixel PX2 may be aligned along the first reference line RFL1 parallel to the long side of the lens. In addition, the first subpixel R43 of the third pixel PX3 may be aligned along the first reference line RFL1. The alignment of the first subpixels R11, R32, and R43 along the first reference line RFL1 may mean that the same point (e.g., the lower left vertex) of the first subpixels R11, R32, and R43 overlaps the first reference line RFL1.

[0072] In addition, the second subpixel G11 of the first pixel PX1 and the second subpixel G32 of the second pixel PX2 may be aligned along an imaginary second reference line RFL2 parallel to the long side of the lens. For example, the second subpixel G11 of the first pixel PX1 and the second subpixel G32 of the second pixel PX2 may be aligned along the second reference line RFL2 parallel to the long side of the lens. In addition, the second subpixel G43 of the third pixel PX3 may be aligned along the imaginary second reference line RFL2.

[0073] like Figure 3 and Figure 4 As shown in , the third sub-pixels B11 to B43, ... may be arranged in a matrix form. In this case, the direction in which the third sub-pixel B11 of the first pixel PX1 and the third sub-pixel B32 of the second pixel PX2 are aligned may not be parallel to the long side. For example, the third sub-pixel B11 of the first pixel PX1 and the third sub-pixel B32 of the second pixel PX2 may be aligned with each other on the third line in a direction not parallel to the long side. In addition, the direction in which the third sub-pixel B11 of the first pixel PX1 and the third sub-pixel B43 of the third pixel PX3 are aligned may be parallel to the long side. In addition, the direction in which the third sub-pixel B11 of the first pixel PX1 and the third sub-pixel B32 of the second pixel PX2 are aligned may not be parallel to the long side. In addition, the direction in which the third sub-pixel B32 of the second pixel PX2 and the third sub-pixel B43 of the third pixel PX3 are aligned may not be parallel to the long side.

[0074] According to the present embodiment, the first sub-pixels R11, R32 and R43 constituting the same viewpoint can display an image with reduced or minimized crosstalk. Meanwhile, the second sub-pixels G11, G32 and G43 constituting the same viewpoint can display an image with reduced or minimized crosstalk.

[0075] According to an embodiment, the contour shapes of the first subpixel R11, the second subpixel G11, and the third subpixel B11 surrounding the first pixel PX1 and the contour shapes of the first subpixel R32, the second subpixel G32, and the third subpixel B32 surrounding the second pixel PX2 may be different from each other. For example, when the contour shape of the first pixel PX1 is a rectangle, the contour shape of the second pixel PX2 may not be a rectangle. For example, the first subpixel R32 of the second pixel PX2 may protrude (e.g., a protruding shape) in a direction opposite to the second direction DR2 relative to the third subpixel B32.

[0076] The outline shape of the first subpixel R11, the second subpixel G11 and the third subpixel B11 surrounding the first pixel PX1 may be the same as the outline shape of the first subpixel R21, the second subpixel G21 and the third subpixel B21 surrounding the pixels positioned in the second direction DR2 from the first pixel PX1 (e.g., a rectangular shape).

[0077] The contour shape of the first subpixel R32, the second subpixel G32 and the third subpixel B32 surrounding the second pixel PX2 may be the same as the contour shape of the first subpixel R42, the second subpixel G42 and the third subpixel B42 surrounding the pixels positioned in the second direction DR2 from the second pixel PX2 (e.g., a protruding shape).

[0078] According to an embodiment, at least some of the first sub-pixels R31, R32, and R33 of the pixels ..., PX2, ... arranged in the first direction DR1 among the pixels PX1, PX2, PX3, ... may have different coordinates in the second direction DR2. For example, although the coordinates of the first sub-pixels R31 and R33 in the second direction DR2 are the same, the first sub-pixel R32 may be positioned in a direction opposite to the second direction DR2 with respect to the first sub-pixels R31 and R33.

[0079] At least some of the second sub-pixels G31, G32, and G33 of the pixels ..., PX2, ... arranged in the first direction DR1 among the pixels PX1, PX2, PX3, ... may have different coordinates in the second direction DR2. For example, although the coordinates of the second sub-pixels G31 and G33 in the second direction DR2 are the same, the second sub-pixel G32 may be positioned in a direction opposite to the second direction DR2 relative to the second sub-pixels G31 and G33.

[0080] The third subpixels B31, B32, and B33 of the pixels ..., PX2, ... arranged in the first direction DR1 among the pixels PX1, PX2, PX3, ... may have the same coordinates as each other in the second direction DR2. More generally, the third subpixels of the pixels arranged in the first direction DR1 among the pixels PX1, PX2, PX3, ... may have the same coordinates as each other in the second direction DR2.

[0081] Reference Figure 5 , the alignment of the first sub-pixels R11 and R32 and the second sub-pixels G11 and G32 will be mathematically described. The first direction DR1 may be defined as the X-axis direction, and the second direction DR2 may be defined as the Y-axis direction. The coordinates of the upper left vertex of the first sub-pixel R11 may be defined as (0, 0). In this case, the Y-axis coordinate of the lower left vertex pr32 of the first sub-pixel R32 may be defined by the following equation 1. Since the X-axis coordinate of the lower left vertex pr32 of the first sub-pixel R32 is the same as that of the conventional S-stripe structure, further description thereof will be omitted.

[0082] [Equation 1]

[0083] R32y=Ry+PPP / tan(SAG)

[0084] Referring to Equation 1, R32y may be the Y-axis coordinate of the lower left vertex pr32 of the first subpixel R32, Ry may be the length of the first subpixel R11 in the Y-axis direction, PPP may be a pitch of one pixel (e.g., the X-axis distance from the left edge of the first pixel PX1 to the left edge of the second pixel PX2), and tan(SAG) may be the tangent value of the first angle SAG. Here, the first angle SAG is the angle formed between the first reference line RFL1 and the Y-axis direction.

[0085] In addition, the Y-axis coordinate of the lower left vertex pg32 of the second subpixel G32 may be defined by the following Equation 2. The X-axis coordinate of the lower left vertex pg32 of the second subpixel G32 is the same as that of the conventional S-stripe structure, and thus a description thereof will be omitted.

[0086] [Equation 2]

[0087] G32y=Ry+Gy+PDLG+PPP / tan(SAG)

[0088] Referring to Equation 2, G32y may be the Y-axis coordinate of the lower left vertex pg32 of the second subpixel G32, Ry may be the length of the first subpixel R11 in the Y-axis direction, Gy may be the length of the second subpixel G11 in the Y-axis direction, PDLG may be the distance between the first subpixel R11 and the second subpixel G11, PPP may be the pitch of one pixel (for example, the X-axis distance from the left edge of the first pixel PX1 to the left edge of the second pixel PX2), and tan(SAG) may be the tangent value of the first angle SAG.

[0089] In an embodiment, the distance between the first subpixel R11 and the second subpixel G11 of the first pixel PX1 may be the same as the distance between the first subpixel R32 and the second subpixel G32 of the second pixel PX2. In this case, since the distance PDLG between the first subpixel and the second subpixel may be maintained, the distance between the first subpixel R32 and the second subpixel G32 may be greater than or equal to a process limit value (e.g., a manufacturing process limit value).

[0091] Reference Figure 6 , the display panel DPc may include a plurality of pixels PX1, PX2, PX3, .... Each of the plurality of pixels PX1, PX2, PX3, ... includes an arrangement of sub-pixels. In the display panel DPc, the arrangement of sub-pixels in different pixels may be different. For example, the positions of the first sub-pixels R11 to R43, ... and the second sub-pixels G11 to G43, ... may be different relative to the third sub-pixels B11 to B43.

[0092] In the display panel DPc, the second subpixel G11 of the first pixel PX1 may be positioned in the second direction DR2 from the first subpixel R11. In this case, the first subpixel R32 of the second pixel PX2 may be positioned in the second direction DR2 from the second subpixel G32. That is, the arrangements of the first subpixel and the second subpixel of the first pixel PX1 and the second pixel PX2 may be opposite to each other. Meanwhile, the second subpixel G43 of the third pixel PX3 may be positioned in the second direction DR2 from the first subpixel R43.

[0093] According to the embodiment, crosstalk of the first sub-pixels R11, R22, and R43 emitting light of the same viewpoint may be reduced. At the same time, crosstalk of the second sub-pixels G11, G32, and G43 emitting light of the same viewpoint may be reduced.

[0094] In an embodiment, the distance between the first subpixel R11 and the second subpixel G11 of the first pixel PX1 may be the same as the distance between the first subpixel R32 and the second subpixel G32 of the second pixel PX2. In this case, since the distance between the first subpixel and the second subpixel can be maintained, the distance between the first subpixel R32 and the second subpixel G32 may be greater than or equal to the process limit value.

[0095] According to an embodiment, the outline shape of the first subpixel R11, the second subpixel G11 and the third subpixel B11 surrounding the first pixel PX1 and the outline shape of the first subpixel R32, the second subpixel G32 and the third subpixel B32 surrounding the second pixel PX2 may be the same (eg, a rectangular shape).

[0096] The second subpixel G21 of the pixel located in the second direction DR2 from the first pixel PX1 may be located in the second direction DR2 from the first subpixel R21 .

[0097] The first subpixel R42 of the pixel located in the second direction DR2 from the second pixel PX2 may be located in the second direction DR2 from the second subpixel G42.

[0098] According to an embodiment, at least some of the first sub-pixels R31, R32, and R33 of the pixels ..., PX2, ... arranged in the first direction DR1 among the pixels PX1, PX2, PX3, ... may have different coordinates in the second direction DR2. For example, although the coordinates of the first sub-pixels R31 and R33 in the second direction DR2 are the same, the first sub-pixel R32 may be positioned relative to the first sub-pixels R31 and R33 in the second direction DR2.

[0099] At least some of the second sub-pixels G31, G32, and G33 of the pixels ..., PX2, ... arranged in the first direction DR1 among the pixels PX1, PX2, PX3, ... may have different coordinates in the second direction DR2. For example, although the coordinates of the second sub-pixels G31 and G33 in the second direction DR2 are the same, the second sub-pixel G32 may be positioned in a direction opposite to the second direction DR2 relative to the second sub-pixels G31 and G33.

[0100] The third sub-pixels B31, B32, and B33 of the pixels ..., PX2, ... arranged in the first direction DR1 among the pixels PX1, PX2, PX3, ... may have the same coordinates as each other in the second direction DR2. More generally, the third sub-pixels of the pixels PX1, PX2, PX3, ... arranged in the first direction DR1 among the pixels PX1, PX2, PX3, ... may have the same coordinates as each other in the second direction DR2.
