Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
The present invention provides a display device, as shown in fig. 2 and fig. 3, wherein the display device includes a display panel 100 and a grating 200 cooperating with the display panel 100, and the display panel 100 may be a display panel capable of implementing a virtual display, that is, the visual resolution of the display panel 100 is higher than the physical resolution of the display panel.
In the present invention, the position of the grating 200 is not particularly limited, and may be used in combination with the display panel 100 to realize autostereoscopic display. For example, when the display panel 100 is an active light emitting display panel (e.g., an organic light emitting diode display panel), the grating 200 should be disposed at the light emitting side of the display panel 100; when the display panel 100 is a liquid crystal display panel, the light barrier 200 may be disposed on the light-emitting side of the display panel, or the light barrier 200 may be disposed between the light-emitting side of the display panel and the backlight of the display device.
Specifically, the actual resolution of the display panel can be made larger than the physical resolution of the display panel in two ways.
First, as shown in fig. 4, the display panel 100 includes a plurality of sub-pixels, which may be sub-pixels of three colors of red, green, and blue (i.e., a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B), wherein two sub-pixels of different colors constitute a pixel unit, and the colors of three sub-pixels sequentially arranged in the same row are different from each other. As shown in fig. 4, the first pixel unit from left to right includes a red subpixel R and a green subpixel G, the second pixel unit from left to right includes a blue subpixel B and a red subpixel R, the third pixel unit from left to right includes a green subpixel G and a blue subpixel B, and the fourth pixel unit from left to right includes a red subpixel R and a green subpixel G. When displaying, the first pixel unit from left to right borrows the blue sub-pixel B of the second pixel unit from left to right, and similarly, the second pixel unit from left to right can borrow the green sub-pixel G of the third pixel unit from left to right. Since each pixel cell includes only two sub-pixels, a display panel including the pixel cell shown in fig. 4 may have a higher PPI and a higher visual resolution by pixel borrowing between adjacent pixel cells. In such an embodiment, the color of each sub-pixel in the same column may be the same, i.e., the arrangement of sub-pixels of different colors in each row is the same; the color of each sub-pixel in the same column may also be different, i.e., the arrangement of the sub-pixels in different colors in each row is different.
Second, as shown in fig. 5 to 12, the plurality of sub-pixels may be sub-pixels of four colors of red, green, blue and supplementary colors (i.e., a red sub-pixel R, a green sub-pixel G, a blue sub-pixel B and a supplementary color sub-pixel), and the four sub-pixels of different colors are arranged in two rows and two columns to form a pixel unit, wherein the colors of any four sub-pixels sequentially arranged in the same row are different from each other, and/or the colors of the four sub-pixels located in two adjacent rows are different from each other in any two adjacent columns of sub-pixels. Similar to the first embodiment shown in fig. 2, the sub-pixels in one pixel unit and the sub-pixels in the adjacent pixel units may borrow each other to realize that the colors of the adjacent four sub-pixels in the same row are different from each other, and the colors of the four sub-pixels in the two adjacent rows are different from each other in any two adjacent columns of sub-pixels, so that the visual resolution of the display panel can be made larger than the physical resolution of the display panel.
The display panel of the second aspect has a higher visual resolution than the physical resolution of the display panel, and therefore, when the display device is used for autostereoscopic display, an image having a higher visual resolution can be obtained, that is, the resolution of the display device can be improved.
In the display panel of the second embodiment, as a specific embodiment, in adjacent pixel units located in the same row, the sub-pixel of the first row of the pixel unit in the previous column is the same as the sub-pixel of the second row of the pixel unit in the next column, and the sub-pixel of the second row of the pixel unit in the previous column is the same as the sub-pixel of the first row of the pixel unit in the next column. For example, as shown in fig. 5, the first row of sub-pixels of the previous column of pixel units are the red sub-pixel R and the green sub-pixel G, the second row of sub-pixels are the complementary color sub-pixel and the blue sub-pixel B, while the first row of sub-pixels of the same row of the next column of pixel units are the complementary color sub-pixel and the blue sub-pixel B, and the second row of sub-pixels are the red sub-pixel R and the green sub-pixel G. As can be seen from the figure, the four sub-pixels arranged in any order in the same plane are different in color from each other. And in the two adjacent columns of sub-pixels, any two adjacent rows of sub-pixels comprise four sub-pixels with complementary and same colors. In this embodiment, the color of each sub-pixel in the same column is not particularly limited. The arrangement of the pixel units in different rows may be the same or different.
In the present invention, the display panel of the second aspect is not particularly limited to the complementary color, and the complementary color may be any one of white, yellow, and the like, for example. To improve the color gamut of the display panel, the supplemental color may preferably be yellow, and the supplemental color subpixel may be a yellow subpixel Y.
When the complementary color sub-pixel is a yellow sub-pixel, as a specific embodiment of the present invention, in each of the pixel units, the red sub-pixel and the green sub-pixel are located in the same row, and the yellow sub-pixel and the blue sub-pixel are located in the same row. Several pixel borrowing methods for pixels in a display panel are described below.
Fig. 5 shows a first borrowing relationship between sub-pixels in a display panel of the display device provided by the present invention. As shown in the figure, in displaying, the red sub-pixel R and the green sub-pixel G in the dashed line box may be borrowed from the yellow sub-pixel Y and the blue sub-pixel B in the previous line of sub-pixels, the yellow sub-pixel Y and the blue sub-pixel B in the next line of sub-pixels, the blue sub-pixel B and the yellow sub-pixel Y in the same line and on the left side of the red sub-pixel R and the green sub-pixel G in the dashed line box, and the yellow sub-pixel Y and the blue sub-pixel B in the same line and on the right side of the red sub-pixel R and the green sub-pixel G in the dashed line box. The visual resolution of the display panel can be improved by this borrowing.
Fig. 6 shows a second borrowing relationship between sub-pixels in a display panel of the display device according to the present invention. As shown in the figure, the red sub-pixel R and the green sub-pixel G in the dotted triangle borrow the yellow sub-pixel Y and the blue sub-pixel B in the previous row, the yellow sub-pixel Y and the blue sub-pixel B in the next row, and the yellow sub-pixel Y and the blue sub-pixel B in the pixel unit of the previous column when displaying.
Fig. 7 shows a third borrowing relationship between sub-pixels in a display panel of the display device provided by the present invention. As shown in the figure, in displaying, the red sub-pixel R and the green sub-pixel G located in the overlapping portion of the two dotted line frames borrow the yellow sub-pixel Y and the blue sub-pixel B in the previous row of sub-pixels and the yellow sub-pixel Y and the blue sub-pixel B in the next row of sub-pixels.
Fig. 8 shows a fourth borrowing relationship between sub-pixels in the display panel of the display device provided by the present invention. In displaying, the red sub-pixel B and the green sub-pixel G in the overlapping part of the two dashed boxes can borrow the yellow sub-pixel Y and the blue sub-pixel B in the next column of pixel units in the same row and the yellow sub-pixel Y and the blue sub-pixel B in the next row of sub-pixels.
The specific structure of the grating in the present invention is not particularly limited, as long as the grating can be matched with the display panel 100 to realize naked eye stereoscopic display. In order to enable the display device to be switchable between a autostereoscopic display mode and a flat display mode, the grating may preferably be a liquid crystal grating. Specifically, as shown in fig. 2 and 3, the grating 200 includes a first substrate 210, a plurality of first electrode bars 211 disposed on the first substrate 210, a second substrate 220 disposed opposite to the first substrate 210, a plate electrode 221 disposed on the second substrate 220, a liquid crystal layer 230 filled between the first substrate 210 and the second substrate 220, and a grating control circuit (not shown) for supplying a first signal to the first electrode bars 211 and a second signal to the plate electrode 221, the plurality of first electrode bars 211 are disposed at intervals (i.e., there is no electrical connection between adjacent two first electrode bars 211 as shown in the figure), and each of the first electrode bars 211 and the plate electrode 221 is made of a transparent electrode material (e.g., an indium tin oxide material).
When the display device is in the flat display mode, light can transmit through the liquid crystal molecules in the liquid crystal layer 230, and the light-transmitting and light-impermeable stripes are not formed on the grating 200, so that the display device can realize flat display. When the display device is in a naked eye stereoscopic display mode, light-transmitting and light-tight stripes are formed on the grating 200 at intervals, so that the display device realizes naked eye stereoscopic display.
The grating may be controlled in two ways according to the initial arrangement of the liquid crystal molecules in the liquid crystal layer 230.
First, when the initial alignment of the liquid crystal layer 230 is such that it can transmit light: in order to realize the flat display of the display device, the grating control circuit does not provide signals to the first electrode strips 211 and does not provide signals to the second electrode strips 212, so that the liquid crystal molecules in the liquid crystal layer 230 are not deflected, light can penetrate through the grating 200, and the display device can realize the flat display; in order to enable the display device to be in a naked eye stereoscopic display mode, the grating control circuit provides a first signal to the first electrode stripes 211 and provides a second signal to the plate electrodes 221, so that an electric field is formed between the first electrode stripes 211 and the plate electrodes 221, and liquid crystal molecules corresponding to the first electrode stripes 211 are deflected, so that regions corresponding to the first electrode stripes 211 are opaque regions, and liquid crystal molecules not corresponding to the first electrode stripes 211 are not deflected, so that regions not corresponding to the first electrode stripes 211 (i.e., regions between two adjacent first electrode stripes 211) are transparent regions, so that light-transmitting and light-opaque stripes are formed on the grating 200 at intervals, and the display device realizes naked eye stereoscopic display.
Second, when the initial alignment of the liquid crystal layer 230 is not transmissive: in order to realize the flat display of the display device, the grating control circuit provides signals to the first electrode strips 211 and the second electrode strips 212 to deflect the liquid crystal molecules in the liquid crystal layer 230, so that light can penetrate through the grating 200, and the display device can realize the flat display; in order to enable the display device to be in a naked eye stereoscopic display mode, the grating control circuit provides a first signal to the first electrode strips 211 and provides a second signal to the plate electrodes 221, so that an electric field is formed between the first electrode strips 211 and the plate electrodes 221, and liquid crystal molecules corresponding to the first electrode strips 211 are deflected, therefore, regions corresponding to the first electrode strips 211 are light-transmitting regions, liquid crystal molecules corresponding to the second electrode strips 212 are not deflected and are light-opaque regions, and alternate light-transmitting and light-opaque stripes are formed on the grating 200, so that the display device can achieve naked eye stereoscopic display.
In order to ensure that only the liquid crystal molecules corresponding to the first electrode stripes 211 are deflected when the display device is in the autostereoscopic display mode, preferably, as shown in fig. 3, the grating 200 may further include at least one second electrode stripe 212 disposed on the first substrate 210, one side of the first electrode stripe 211 is the second electrode stripe 212, the other side of the first electrode stripe 211 is a boundary of the grating 200 or the second electrode stripe 212, and the second electrode stripe 212 is made of a transparent electrode material (e.g., an indium tin oxide material), and the grating control circuit may provide the second signal to the second electrode stripe 212.
When the display device is in a autostereoscopic display mode, the raster control circuit provides a first signal to the first electrode stripes 211, while the raster control circuit provides a second signal to the second electrode stripes 212 and the plate electrodes 221. There is no voltage difference between the second electrode stripes 212 and the plate electrodes 221, and therefore there is no electric field between the second electrode stripes 212 and the plate electrodes, and therefore, the liquid crystal molecules at the positions corresponding to the second electrode stripes 212 are not deflected. Therefore, after the second electrode strips 212 are arranged, the liquid crystal molecules at the positions corresponding to the second electrode strips 212 are ensured not to deflect, so that light can be ensured to penetrate through the areas corresponding to the second electrode strips 212, and the display effect when naked eye three-dimensional display is realized by using the display device is ensured.
In the present invention, the specific number of the second electrode stripes 212 is not specifically shown, for example, the number of the second electrode stripes 212 may be the same as the number of the first electrode stripes 211, and of course, the number of the second electrode stripes 212 may be different from the number of the first electrode stripes 211. In order to ensure that the area between two adjacent first electrode stripes 21 can better pass through light when the display device is used for naked eye stereoscopic display, preferably, the second electrode stripes 212 may be multiple, and the first electrode stripes 211 and the second electrode stripes 212 are alternately arranged.
In order to increase the light transmittance of the grating, so as to improve the display effect of the display device in the flat display mode and the display resolution in the autostereoscopic display mode, as shown in fig. 3, the grating 200 may further include a retardation plate 240 disposed on the light incident surface of the second substrate 220, and the retardation plate 240 may convert the linearly polarized light incident into the retardation plate 240 into a direction in which the vibration direction coincides with the light transmission axis of the liquid crystal molecules in the initial alignment state in the liquid crystal layer 230.
In the present invention, the specific arrangement and size of the first electrode stripes 211 are not particularly limited, and it is preferable that the plurality of pixel cells in the regions corresponding to the first electrode stripes on the display panel satisfy a borrowing relationship when the display device performs display, and the plurality of pixel cells in the regions corresponding to the second electrode stripes on the display panel satisfy the borrowing relationship when the display device performs display. It is easy to understand that all the images displayed on the regions of the display panel corresponding to the first electrode bars enter one eye of an observer, and all the images displayed on the regions of the display panel corresponding to the second electrode bars enter the other eye of the observer, so that naked-eye stereoscopic display can be realized. Since the pixel cells in the region corresponding to the first electrode bar satisfy the borrowing relationship during display and the pixel cells in the region corresponding to the second electrode bar also satisfy the borrowing relationship during display, the visual resolution of an image displayed in the region corresponding to the first electrode bar is higher than the physical resolution of the region, and the visual resolution of an image displayed in the region corresponding to the second electrode bar is higher than the physical resolution of the region. Therefore, when the display device provided by the invention is used for naked eye stereoscopic display, higher visual resolution can be obtained.
As an embodiment of the present invention, as shown in fig. 9, 12 and 13, one first electrode stripe 211 and one second electrode stripe (not shown in fig. 9) each correspond to two columns of pixel units on the display panel.
When the display panel is driven in the subpixel borrowing manner shown in fig. 9, subpixels in a region between two first electrode stripes 211 (i.e., a region corresponding to a second electrode stripe) satisfy a subpixel borrowing relationship shown by a dotted triangle. Similarly, the sub-pixels in the region corresponding to the first electrode stripes 211 also satisfy the same sub-pixel borrowing relationship.
When the display panel is driven in the subpixel borrowing manner shown in fig. 12, subpixels in a region between two first electrode stripes 211 (i.e., a region corresponding to a second electrode stripe) satisfy a subpixel borrowing relationship shown by a dotted square frame or satisfy a subpixel borrowing relationship shown by a dotted rectangular frame. Similarly, the sub-pixels in the region corresponding to the first electrode stripes 211 also satisfy the same sub-pixel borrowing relationship.
When the display panel is driven in the subpixel borrowing manner shown in fig. 13, subpixels in the region between the two first electrode stripes 211 (i.e., the region corresponding to the second electrode stripe) satisfy the subpixel borrowing relationship shown by the dotted line frame. Similarly, the sub-pixels in the region corresponding to the first electrode stripes also satisfy the same sub-pixel borrowing relationship.
Alternatively, as shown in fig. 11, the first electrode bars 211 and the second electrode bars (not shown in fig. 10) each correspond to three columns of pixels on the display panel. It should be noted that the sub-pixels in the region corresponding to the first electrode stripes 211 satisfy the sub-pixel borrowing relationship when the display panel is driven, and the sub-pixels in the region corresponding to the second electrode stripes also satisfy the sub-pixel borrowing relationship when the display panel is driven.
Alternatively, the first electrode stripes 211 may be arranged according to the embodiment shown in fig. 10, the first electrode stripes 211 being arranged obliquely to the edge of the first substrate, and the second electrode stripes (not shown in fig. 10) being parallel to the first electrode stripes 211. It should be noted that the sub-pixels in the region corresponding to the first electrode stripes 211 satisfy the sub-pixel borrowing relationship when the display panel is driven, and the sub-pixels in the region corresponding to the second electrode stripes also satisfy the sub-pixel borrowing relationship when the display panel is driven.
In the present invention, there is no particular limitation on the specific structure of the display panel 100, and for example, the display panel may be a liquid crystal display panel or an OLED display panel. The display panel 100 shown in fig. 2 and 3 is a liquid crystal display panel. As shown in fig. 3, the display panel 100 includes a polarizer 121 disposed on a light incident surface of the display panel, an array substrate 120, a liquid crystal layer 130, a color film layer 113, a pair of cell substrates 112, and a polarizer 111 disposed on a light emergent surface of the display panel.
When the liquid crystal molecules in the liquid crystal layer 230 are initially arranged in a manner that they can transmit light, the polarization direction of the polarizer 213 of the grating 200 is the same as the polarization direction of the polarizer 111 disposed on the light-emitting surface of the display panel. When the initial arrangement of the liquid crystal molecules in the liquid crystal layer 230 is opaque, the polarization direction of the polarizer 213 of the grating 200 is perpendicular to the polarization direction of the polarizer 111 disposed at the light emitting surface of the display panel. In this case, when the first electrode stripes 211 and the second electrode stripes 212 are simultaneously energized, liquid crystal molecules in the liquid crystal layer 230 are deflected, thereby achieving a transparent state.
It is easily understood that the polarizing plate 213 of the grating 200 is disposed on the light exit surface of the grating 200. The color film layer 113 is provided with a plurality of sub-pixels, and the arrangement of the sub-pixels satisfies the arrangement of the present invention described above.

For example, the grating 200 may be fixed on the light emitting surface of the display panel 100 by a connector such as a snap, a clip, or the like. In order to simplify the structure of the display device, preferably, as shown in fig. 2 and 3, the display device may include a first adhesive member 300, the first adhesive member 300 being disposed around the barrier 200 to adhere the barrier 200 and the display panel 100 together.
In order to increase the connection strength between the display panel 100 and the optical grating 200, preferably, the display device may include a transparent second adhesive member disposed on the light emitting surface of the display panel to adhere the optical grating and the display panel together. The second adhesive member may be disposed over the entire light emitting surface of the display panel, or may be disposed on only a portion of the light emitting surface of the display panel.
