For ease of understanding, a multi-layer display device according to an embodiment of the present invention will be briefly described below:
as described above, the conventional RGB display is more commonly used as a combination of the conventional RGB display, in which the sub-pixels of the upper layer and the sub-pixels of the lower layer are arranged in one-to-one correspondence, that is, the R sub-pixels of the upper layer and the R sub-pixels of the lower layer are arranged in correspondence, and the R sub-pixels of the upper layer display color (red), so that the transmittance is lower when the light transmitted through the R sub-pixels of the lower layer passes through the R sub-pixels of the upper layer again, which affects the display brightness of the multi-layer display device. In addition, the light transmitted through the lower R sub-pixel will be emitted to the R sub-pixel of the upper R sub-pixel, and to the G sub-pixel and the B sub-pixel adjacent to the upper R sub-pixel, so that the light transmitted through the upper G sub-pixel and the B sub-pixel is doped with red light, which causes color shift phenomenon, and affects the display quality of the multi-layer display device.
According to an embodiment of the present invention, the multi-layer display device includes a plurality of display units, each of the pixel units in the display units includes a first sub-pixel and a second sub-pixel, the first sub-pixel is white, the second sub-pixel includes a plurality of colors, and the second sub-pixel in any one of the display units, in front projection in the other display units, covers the first sub-pixel in the other display units, that is, in a direction in which the plurality of display units are stacked, the first sub-pixel corresponds to the second sub-pixel, so that, when the multi-layer display device is in operation, light transmitted through the second sub-pixel can transmit the first sub-pixel corresponding to the second sub-pixel to represent the color of the second sub-pixel, or light transmitted through the first sub-pixel can transmit the second sub-pixel to represent the color of the second sub-pixel, thereby significantly improving the transmittance of light, improving the display brightness of the multi-layer display device, and the light transmitted through the second sub-pixel in the lower display unit will be transmitted to the first sub-pixel in the upper display unit and transmitted to the sub-pixel adjacent to the first sub-pixel in the upper display unit, for example, referring to fig. 1, the first second sub-pixel 20 in the lower display unit 100C may be an R sub-pixel, the light transmitted through the R sub-pixel in the display unit 100C is transmitted to the corresponding white (W) sub-pixel in the display unit 100B, and the light transmitted through the W sub-pixel is continuously transmitted to the corresponding W sub-pixel in the display unit 100A, so as to finally display red, effectively reduce color shift, improve the display quality of the multi-layer display device, and multiple display units may display different images, through superposition, display mixed image effects, the multi-layer display device has rich display effect.
The following describes in detail the respective structures of the multi-layer display device according to the embodiments of the present invention:
the specific color and number of the second sub-pixels in each pixel unit are not particularly limited, and those skilled in the art can design according to the actual color. For example, according to an embodiment of the present invention, the color of the second sub-pixel 20 may include red, green, or blue, that is, the pixel unit in each display unit 100 may include R, G, B and W four sub-pixels. Therefore, the red, green and blue sub-pixels can display different colors so as to enable the display unit to display different images, and the white sub-pixels are used for enabling the white sub-pixels corresponding to the red, green and blue sub-pixels to be white in the direction of stacking the display units, so that the light transmittance of the red, green and blue sub-pixels can be increased, the color shift can be reduced, and the display brightness and the display quality of the multi-layer display device can be improved.
According to an embodiment of the present invention, a plurality of sub-pixels in a pixel unit in each display unit may be arranged in a row, and an arrangement order of second sub-pixels in each pixel unit in the plurality of display units is identical. It should be noted that "the arrangement order of the second sub-pixels in each pixel unit in the plurality of display units is identical" only refers to the arrangement order of the second sub-pixels of the plurality of different colors, and does not relate to the arrangement of the first sub-pixels. Specifically, taking the case where the color of the second sub-pixel includes red, green, and blue as an example, if the second sub-pixel in one display unit is arranged in the order of RGB, the second sub-pixels in the other display units are also arranged in the order of RGB, and in the direction in which the plurality of display units are stacked, the W sub-pixels correspond to the R, G, B sub-pixels. Therefore, the multi-layer display device can simultaneously display images displayed by a plurality of display units, and light rays transmitted through the second sub-pixels on the lower layer can be emitted from the first sub-pixels on the upper layer, so that the light transmittance is increased, the color shift is reduced, and the brightness and the display quality of the multi-layer display device are improved.
The arrangement order of the sub-pixels in each display unit is not particularly limited as long as the first sub-pixel corresponds to the second sub-pixel in the direction in which the plurality of display units are stacked. For example, according to an embodiment of the present invention, the multi-layer display device may be a dual-layer display device, that is, the multi-layer display device may include two display units, the sub-pixels in the first display unit may be arranged according to RGBWWW, the sub-pixels in the second display unit may be arranged according to WWWRGB, that is, the arrangement order of the second sub-pixels in the upper and lower display units is identical (both are the order of RGB), and in the direction in which the two display units are stacked, the first sub-pixels correspond to the second sub-pixels, and the above pixel design may significantly improve the light transmittance and effectively reduce the color shift.
Specifically, the light transmitted through the R sub-pixel in the second display unit will be emitted to the corresponding W sub-pixel in the first display unit, and to the B sub-pixel and the W sub-pixel adjacent to the W sub-pixel in the first display unit. In the mode of combining the RGB display with the RGB display in the prior art, the light transmitted through the R sub-pixel of the lower layer is emitted to the R sub-pixel of the upper layer, and is emitted to the G sub-pixel and the B sub-pixel of the upper layer adjacent to the R sub-pixel. It should be noted that the pixel design of the present embodiment may be applied to a dual-layer display device with higher resolution.
According to the preferred embodiment of the present invention, the arrangement of the sub-pixels in the pixel units in the plurality of display units 100 is consistent, and the adjacent two second sub-pixels 20 in each display unit 100 may be separated by the first sub-pixel 10 and located between two pixel units in the adjacent two display units 100 with a position shifted by one sub-pixel. Therefore, the second sub-pixels on the upper layer and the lower layer can be staggered, so that the multi-layer display device can simultaneously display images displayed by a plurality of display units, light rays passing through the second sub-pixels on the lower layer can be emitted from the first sub-pixels on the upper layer, the light transmittance is increased, the color cast is reduced, and the brightness and the display quality of the multi-layer display device are improved. The "position shifted by one sub-pixel between two pixel units in two adjacent display units 100" means that the distance between the front projection of the pixel unit in the first display unit on the second display unit and the pixel unit corresponding to the pixel unit in the second display unit is one sub-pixel. Therefore, the staggered arrangement of the sub-pixels in the upper and lower display units can be realized, so that the light transmitted through the sub-pixels in the lower layer can transmit through the sub-pixels in the upper layer with high transmittance.
Specifically, referring to fig. 2, taking a dual-layer display device as an example, the multi-layer display device may include two display units 100, where sub-pixels in pixel units of the two display units 100 are arranged uniformly, and each of the two second sub-pixels (R, G, B sub-pixels) located in the same pixel unit and adjacent to each other in each display unit 100 are separated by a first sub-pixel (W sub-pixel): the arrangement of the subpixels in the pixel units in the display unit 100B and the display unit 100A may be identical, and in the above pixel design, two adjacent second subpixels, for example, between R and G, or between G and B, are all separated by one W subpixel, and the RWGWBW pixel units in the display unit 100A and the RWGWBW pixel units in the display unit 100B are staggered by one W subpixel, so that the R, G, B subpixels in the pixel units in the display unit 100A and the R, G, B subpixels in the pixel units in the display unit 100B are staggered by one W subpixel, so that the first subpixels corresponding to the second subpixels are realized in the direction in which the multiple display units are stacked, and the dual-layer display device has higher display brightness and higher display quality.
Specifically, the light transmitted through the R sub-pixel in the display unit 100B may be emitted to the corresponding W sub-pixel in the display unit 100A, and to the R sub-pixel and the B sub-pixel adjacent to the W sub-pixel in the display unit 100A, which not only significantly improves the light transmittance, but also effectively reduces the color shift, thereby improving the display brightness and the display quality of the dual-layer display device.
According to an embodiment of the present invention, all the data lines connected to the first sub-pixel 10 in each display unit 100 are connected to the same port. Therefore, in each display unit, voltages can be simultaneously applied to all the first sub-pixels to drive the first sub-pixels together, so that power can be saved, driving ICs (integrated circuits) can be reduced, and cost can be reduced. Specifically, referring to fig. 3, taking a dual-layer display device as an example, the data lines for controlling the sub-pixels in each display unit are disposed on the array substrate 110, the data lines of all the W sub-pixels in each display unit are connected together, and the data lines S4 simultaneously input voltages to all the W sub-pixels to realize the common driving of all the W sub-pixels, the R, G, B sub-pixels in each display unit are respectively input voltages by separate data lines, for example, the R sub-pixels are connected with the data lines S1, the G sub-pixels are connected with the data lines S2, the B sub-pixels are connected with the data lines S3, that is, the R, G, B sub-pixels in each display unit can be driven by adopting the existing data line connection mode, and the data lines of all the W sub-pixels are connected together to commonly drive, so that the power is saved, the cost is reduced, and the compatibility is good.
According to the embodiment of the invention, in the multi-layer display device, a rubber frame is arranged between two adjacent display units. That is, two adjacent display units can be connected through the rubber frame, and two adjacent display units are overhead and fixed through the rubber frame, so that the lamination setting of a plurality of display units is realized, air is arranged between two adjacent display units, and light rays penetrating through the lower display unit can directly penetrate through the air to enter the upper display unit. According to the embodiment of the invention, a certain distance exists between two adjacent display units, so that a certain depth of field exists between images displayed by different display units, and a 3D display effect can be realized. The inventor finds that when the distance between two adjacent display units is too large, a color cast phenomenon can be generated, when the distance between the two adjacent display units is too small, the 3D display effect can be unobvious, and the specific distance between the two adjacent display units can be designed according to the requirements of different products on the visual effect. For example, according to an embodiment of the present invention, the distance between two adjacent display units may be 10-20mm, and thus, the distance between two adjacent display units is moderate, an image having a 3D display effect may be presented, and color shift may be effectively reduced.
According to the embodiment of the invention, in order to further reduce color cast, the light guide plate can be arranged between two adjacent display units, the light guide plate is attached to the two display units through optical bonding glue, the light emitting side of the light guide plate is provided with the light guide units which are arranged in an array, and the light guide units can comprise a concave structure. Therefore, when the light transmitted through the lower layer display unit passes through the light guide plate, the light guide unit with the concave structure can be used for gathering the light, so that the light transmitted through the lower layer pixel unit is directly transmitted into the pixel unit corresponding to the upper layer pixel unit, thereby further reducing color cast and further improving the display quality of the multi-layer display device.

The specific kind of the optical adhesive is not particularly limited as long as it is transparent and has good adhesion, and may be selected by those skilled in the art according to the specific circumstances. For example, according to an embodiment of the present invention, the optical bonding paste may be an optically clear resin paste (OCR) or an optical paste (OCA).
According to an embodiment of the present invention, the thickness of the light guide plate 300 may be designed according to the requirements of different products for visual effects. For example, according to an embodiment of the present invention, the thickness of the light guide plate 300 may be 5-20mm, and thus, the thickness of the light guide plate is moderate, an image having a 3D display effect may be displayed, and color shift may be effectively reduced.
According to an embodiment of the present invention, the light guide unit 310 may include one pit, which corresponds to the pixel unit one by one, and the cross-sectional area of the pit is the same as the cross-sectional area of the pixel unit. Therefore, the light passing through the light guide plate can be gathered to the size of one pixel unit and emitted, so that the light passing through the lower pixel unit is not scattered and directly passes through the upper pixel unit, the color shift is further reduced, and the display quality of the multi-layer display device is improved.
