Description

TECHNICAL FIELD

[0001] The present application relates to a display device, and in particular to a display device capable of switching between two-dimensional (2D) and three-dimensional (3D) display modes. BACKGROUND

[0002] Generally, the generation of stereoscopic vision is based on the principle of binocular disparity, that is, when two eyes see slightly different images, the brain will perceive the distance and position of the object according to the differences. Since the left eye and the right eye see different views, the brain will try to combine these images to generate stereoscopic vision.

[0003] The prior art 3D display divides the pixels of a liquid crystal panel into image pairs of odd and even pixels, the odd pixel image pair provides an image for one eye of the viewer, and the even pixel image pair provides an image for the other eye of the viewer. The light is split by a lenticular lens to project the images of the odd and even pixels to the two eyes of the viewer.

[0004] Since the light source of the electronic paper comes from ambient light, if the light is split by a lenticular lens, the incidence and reflection of ambient light will be refracted by the lens, which is easy to generate Moire waves due to the superposition of the pitch between the lens and the pixels, or 3D crosstalk due to the image of one eye being seen by the other eye, and the stereoscopic vision cannot meet most of the viewing angle conditions. Therefore, the electronic paper with 3D display function has not been commercialized in the industry.

[0005] Therefore, there is a lack of a display device with 3D display function and capable of switching between two-dimensional and three-dimensional display modes in the current market, and relevant industries are seeking solutions. SUMMARY

[0006] Therefore, the purpose of the present application is to provide a display device that can present a three-dimensional visual experience by stacking multiple layers of Cholesteric Liquid Crystal Display (ChLCD) monochrome sheets without the need for external lens, and can effectively control the ChLCD to operate in two-dimensional display mode or three-dimensional display mode, to solve the problem of wave or display interference caused by the need for external lens in the prior art.

[0054] Several embodiments of the present disclosure will be described with reference to the drawings. For the purpose of explanation, numerous specific details will be set forth in the description. It should be noted, however, that such details are not to be construed as limiting the present disclosure. Rather, the present disclosure is intended to encompass all modifications and alterations of the disclosed embodiments that are within the scope of the present disclosure. Moreover, for the purpose of clarity, certain conventional aspects of the disclosed embodiments will not be described in detail or will be omitted inasmuch as such aspects are appreciated by one of ordinary skill in the art.

[0055] Furthermore, as used herein, the term "connected" can mean directly connected, and can also mean indirectly connected via one or more other devices or connections. Where the context permits, "connected" can also refer to being "directly connected", i.e. with no other devices or connections interposed therebetween. The term "coupled" can mean directly connected, and can also mean indirectly connected via one or more other devices or connections. Where the context permits, "coupled" can also refer to being "directly coupled", i.e. with no other devices or connections interposed therebetween.

[0056] Cholesterol liquid crystal electronic paper has similar characteristics to electronic ink (e-ink), such as low energy consumption and non-emitting font, making long-time reading more comfortable for the eyes, but unlike existing electronic ink, cholesterol liquid crystal can provide richer color performance, making it more advantageous in displaying color content, becoming an ideal screen choice for e-readers and other electronic devices. The new type utilizes external ambient light and through the superposition of multiple layers of ChLCD monochrome sheets, it can present a three-dimensional visual experience without the need for external lens. The embodiments can be divided into two architectures, namely glasses-type architecture and naked-eye architecture. The glasses-type architecture can display a left-view image and a right-view image, respectively, which enter the left eye and the right eye through circularly polarized glasses to produce stereoscopic vision. The naked-eye architecture can display a foreground image and a background image, respectively, and the focal points of the viewer's two eyes naturally fall on the image position and feel the depth of field to produce a three-dimensional effect. Therefore, the transmitted image information can control the ChLCD to operate in a two-dimensional display mode or a three-dimensional display mode. If the red, green, or / and blue (RGB) upper and lower layers display the same image, it is a two-dimensional display mode, and the three-dimensional display mode is that the upper and lower ChLCDs display (foreground image / back image) or (left view / right view) images, respectively. The details of each embodiment will be described below.

[0057] Please refer to Figure 1 , Figure 1 is a schematic diagram illustrating a display device 100 of a first embodiment of the present application. The display device 100 includes a plurality of display panels, including a first display panel 110, a second display panel 120, a third display panel 130, a fourth display panel 140, a fifth display panel 150, and a sixth display panel 160. The first display panel 110, the second display panel 120, the third display panel 130, the fourth display panel 140, the fifth display panel 150, and the sixth display panel 160 are sequentially stacked (spaced apart from each other). The first display panel 110 displays a first color; the second display panel 120 displays a second color; the third display panel 130 displays a third color; the fourth display panel 140 displays a fourth color; the fifth display panel 150 displays a fifth color; and the sixth display panel 160 displays a sixth color. The first color, the second color, the third color, the fourth color, the fifth color, and the sixth color form a color combination in order, and the color combination does not include the first color, the second color, the third color, the fourth color, the fifth color, and the sixth color being blue, blue, green, green, red, and red, respectively.

[0058] In detail, in the embodiment, the color combination includes the first color, the second color, the third color, the fourth color, the fifth color and the sixth color being blue, green, red, blue, green and red respectively, but the present application is not limited thereto. As known from the color combination, two of the display panels (e.g. the first display panel 110 and the fourth display panel 140) display the same color, and the two of the display panels display the foreground image and the background image respectively, so that the display device 100 operates in the three-dimensional display mode. The two of the display panels are a left-handed cholesteric liquid crystal display panel (CLC Panel) and a right-handed cholesteric liquid crystal display panel respectively. The first display panel 110, the second display panel 120 and the third display panel 130 are right-handed cholesteric liquid crystal display panels; the fourth display panel 140, the fifth display panel 150 and the sixth display panel 160 are left-handed cholesteric liquid crystal display panels. Since the polarization light rotation of the CLC is opposite, the reflected light of the lower CLC can mostly penetrate the upper layer. In this way, the display device 100 of the present application can be applied to the naked-eye electronic paper, and the foreground image and the background image (i.e. the foreground image and the background image) of the image are displayed by setting the RGB left-handed and right-handed CLC respectively, so that the focal point of the line of sight of the viewer's two eyes (right eye and left eye) naturally falls on the image position, and the depth of field is felt.

[0059] Further, the first display panel 110 includes a first liquid crystal layer 112 and two glass layers GL, and the first liquid crystal layer 112 is connected between the two glass layers GL. The second display panel 120 includes a second liquid crystal layer 122 and two glass layers GL, and the second liquid crystal layer 122 is connected between the two glass layers GL. The third display panel 130 includes a third liquid crystal layer 132 and two glass layers GL, and the third liquid crystal layer 132 is connected between the two glass layers GL. The fourth display panel 140 includes a fourth liquid crystal layer 142 and two glass layers GL, and the fourth liquid crystal layer 142 is connected between the two glass layers GL. The fifth display panel 150 includes a fifth liquid crystal layer 152 and two glass layers GL, and the fifth liquid crystal layer 152 is connected between the two glass layers GL. The sixth display panel 160 includes a sixth liquid crystal layer 162 and two glass layers GL, and the sixth liquid crystal layer 162 is connected between the two glass layers GL. In addition, the display device 100 further includes a light absorbing layer 170 (Black) and a plurality of adhesive layers 180. The light absorbing layer 170 is arranged at the lowermost layer of the entire structure and is connected to the sixth display panel 160. The adhesive layer 180 can include an optically clear adhesive (OCA), and is arranged between two adjacent display panels.

[0060] Please refer to Figure 1 and Figure 2 wherein Figure 2is a schematic diagram illustrating a display device 100a of a second embodiment of the present disclosure. The display device 100a includes a plurality of display panels and a light absorption layer 170, the display panels including a first display panel 110, a second display panel 120, a third display panel 130, a fourth display panel 140, a fifth display panel 150, and a sixth display panel 160. Figure 2 The structures of the display panels and the light absorption layer 170 of the display device 100a are the same as those of the display device 100 of the first embodiment of the present disclosure, and are not described again. Figure 1 The structures of the display panels and the light absorption layer 170 of the display device 100a are the same as those of the display device 100 of the first embodiment of the present disclosure, and are not described again. Figure 1 The difference between the display device 100a and the display device 100 of the first embodiment of the present disclosure is that the display device 100a does not have the adhesive layer 180, and two adjacent display panels of the display device 100a are separated by a distance D. Each display panel has a structure (not shown in the figure) that connects other structures to maintain a certain distance D between two adjacent display panels. In an embodiment, the distance D can be greater than 0 cm and less than or equal to 5 cm, but the present disclosure is not limited thereto. In this way, the display device 100a of the present disclosure can be applied to naked-eye electronic paper, and two adjacent display panels can be separated by air instead of being combined by OCA, which can increase the depth of field of imaging and further deepen the three-dimensional visual effect.

[0061] Please refer to Figure 1 and Figure 3 , wherein Figure 3 is a schematic diagram illustrating a display device 100b and a controller 300 of a third embodiment of the present disclosure. The display device 100b includes a plurality of display panels. The display panels are sequentially stacked (spaced apart from each other) and include a first display panel 110b, a second display panel 120b, a third display panel 130b, a fourth display panel 140b, a fifth display panel 150b, and a sixth display panel 160b. The first display panel 110b displays a first color; the second display panel 120b displays a second color; the third display panel 130b displays a third color; the fourth display panel 140b displays a fourth color; the fifth display panel 150b displays a fifth color; and the sixth display panel 160b displays a sixth color. Any one of the first color, the second color, the third color, the fourth color, the fifth color, and the sixth color is one of blue, green, and red, and two of the display panels display the same color. The display device 100b is switched to a two-dimensional display mode or a three-dimensional display mode. When the display device 100b is switched to the two-dimensional display mode, the two display panels display the same image; otherwise, when the display device 100b is switched to the three-dimensional display mode, the two display panels display two images, respectively, and the two images are different from each other.

[0062] In detail, the display device 100b further comprises a circular polarized glasses 200, a light absorption layer 170 and a plurality of adhesive layers 180. The circular polarized glasses 200 faces the first display panel 110b and receives a left-handed polarized light and a right-handed polarized light from the display panel, and comprises two quarter wavelength wave plates 210 (1 / 4 λ retarder) and two linear polarizers 220 (Linear Polarizer). The linear polarizers 220 are stacked with the quarter wavelength wave plates 210, and the two images are a left view angle image and a right view angle image. The left-handed polarized light and the right-handed polarized light pass through the circular polarized glasses 200 at the same time, the right-handed polarized light passes through the quarter wavelength wave plates 210 and is converted into linear polarized light parallel to the fast axis, the left-handed polarized light passes through the quarter wavelength wave plates 210 and is converted into linear polarized light parallel to the slow axis, and the two linear polarizers 220 are parallel to the fast axis and the slow axis, respectively, so as to filter out polarized light of different handedness. The structures of the light absorption layer 170 and the adhesive layers 180 are the same as those of the light absorption layer 170 and the adhesive layers 180 of the display device 100a, and are not described again. Figure 1 The structures of the light absorption layer 170 and the adhesive layers 180 are the same as those of the light absorption layer 170 and the adhesive layers 180 of the display device 100a, and are not described again.

[0063] The display device 100b is electrically connected to the controller 300, and the controller 300 controls the display device 100b to switch between the two-dimensional display mode and the three-dimensional display mode. In addition, the first display panel 110b, the third display panel 130b and the fifth display panel 150b are right-handed cholesteric liquid crystal display panels, and the second display panel 120b, the fourth display panel 140b and the sixth display panel 160b are left-handed cholesteric liquid crystal display panels. Since the polarized light handedness of the CLC is opposite, the reflected light of the lower layer CLC can mostly penetrate the upper layer.

[0064] The first display panel 110b comprises a first liquid crystal layer 112b, the second display panel 120b comprises a second liquid crystal layer 122b, the third display panel 130b comprises a third liquid crystal layer 132b, the fourth display panel 140b comprises a fourth liquid crystal layer 142b, the fifth display panel 150b comprises a fifth liquid crystal layer 152b, and the sixth display panel 160b comprises a sixth liquid crystal layer 162b. The first liquid crystal layer 112b, the second liquid crystal layer 122b, the third liquid crystal layer 132b, the fourth liquid crystal layer 142b, the fifth liquid crystal layer 152b and the sixth liquid crystal layer 162b are electrically connected to the controller 300, and each of them has a glass layer GL on the upper and lower sides. In an embodiment, the first color, the second color, the third color, the fourth color, the fifth color and the sixth color are blue, blue, green, green, red and red, respectively, but the present application is not limited thereto. In this way, the display device 100b of the present application can be applied to glasses-type electronic paper, and the right eye can only see the right view angle image and the left eye can only see the left view angle image, thereby simulating the parallax of the two eyes to generate a stereoscopic effect.

[0065] Please see Figure 3 and Figure 4 ,in Figure 4 This is a schematic diagram illustrating a display device 100c and a controller 300 according to a fourth embodiment of the present invention. The display device 100c includes a plurality of display panels, a light-absorbing layer 170, and a plurality of adhesive layers 180. These display panels are stacked sequentially (spaced apart from each other) and include a first display panel 110c, a second display panel 120c, a third display panel 130c, a fourth display panel 140c, a fifth display panel 150c, and a sixth display panel 160c. The structure of the display panels, light-absorbing layer 170, and adhesive layer 180 of the display device 100c is similar to... Figure 3 The display panel, light-absorbing layer 170, and adhesive layer 180 of the display device 100b have the same structure and will not be described again. Furthermore, the display device 100c is electrically connected to the controller 300, which controls the display device 100c to switch between two-dimensional and three-dimensional display modes. Both display panels display the same color, and the controller 300 controls these two display panels to display a foreground image and a background image respectively, enabling the display device 100c to operate in three-dimensional display mode. Thus, the novel display device 100c, in conjunction with the controller 300, can control whether to operate in three-dimensional or two-dimensional display mode by transmitting different image data. When operating in three-dimensional display mode, the upper and lower ChLCD layers display images of (front image / rear image) or (left viewing angle / right viewing angle) respectively; when operating in two-dimensional display mode, the upper and lower RGB same-color ChLCD layers display the same image. Therefore, the novel display device 100c can be applied to naked-eye electronic paper, and compared with the existing three-layer ChLCD structure, the novel has a higher reflectivity (R%).

[0066] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in Figure 5 This is a flowchart illustrating a display method S0 of a display device according to a fifth embodiment of the present invention. Display method S0 can be applied to the aforementioned display devices 100, 100a, 100b, and 100c. Display method S0 includes steps S02 and S04. Step S02 includes providing a display device 100, 100a, 100b, and 100c. Step S04 includes controlling the display devices 100, 100a, 100b, and 100c via a controller 300, causing the display devices 100, 100a, 100b, and 100c to switch to a two-dimensional display mode or a three-dimensional display mode. Furthermore, for applications... Figure 3The display device 100b structure (glasses type architecture), the display method S0 can also contain providing a circularly polarized glasses 200 facing the first display panel 110b, so that the circularly polarized glasses 200 receives a left-handed polarized light and a right-handed polarized light from the display panel. By this, the display method S0 of the new type of display device 100, 100a, 100b, 100c containing the superposition of multiple layers of ChLCD monochrome sheet, without the need for external lens, can present a three-dimensional visual experience, and can effectively control the ChLCD to operate in two-dimensional display mode or three-dimensional display mode, to solve the problem of the prior art that the external lens is easy to produce ripple or display interference.

[0067] Please refer to Figure 3 and Figure 6 , wherein Figure 6 is a schematic diagram illustrating the display device 100d of the sixth embodiment of the new type. The display device 100d contains a plurality of display panels, a light absorption layer 170, an adhesive layer 180 and a circularly polarized glasses 200. Among them, the display panels are sequentially stacked (spaced apart from each other), and contain a first display panel 110d and a second display panel 120d. The first display panel 110d displays a first color. The second display panel 120d displays a second color, and the second color is the same as the first color (for example: blue). The display device 100d is switched to a two-dimensional display mode or a three-dimensional display mode. When the display device 100d is switched to the two-dimensional display mode, the first display panel 110d and the second display panel 120d display the same image; on the contrary, when the display device 100d is switched to the three-dimensional display mode, the first display panel 110d and the second display panel 120d respectively display two images, and the two images are different from each other. The structure of the first display panel 110d, the second display panel 120d, the light absorption layer 170, the adhesive layer 180 and the circularly polarized glasses 200 is the same as that of the first display panel 110b, the second display panel 120b, the light absorption layer 170, the adhesive layer 180 and the circularly polarized glasses 200 of Figure 3 .
