In an embodiment, the light emitting member 102 has a light emitting side, and the light emitting side of the light emitting member 102 is disposed toward the top wall of the device housing.

Thus, the arrangement position and the installation stability of the polarizer 104 are ensured, and more importantly, the polarizer 104 can be directly arranged on the touch layer 128, so that the polarizer 104 is supported by the touch layer 128, and the polarizer 104 and the touch layer 128 can be integrated, thereby greatly reducing the thickness of the polarizer 104 and further realizing the light and thin design of the optical element.
In a specific application, the polarizer 104 may be formed by evaporating a metal layer on the touch layer 128, then coating an imprint resist, and then performing nanoimprint and etching.
As a possible embodiment, as shown in fig. 5, the element housing includes a cover 124. The polarizer 104 is integrally disposed on an end surface of the cover 124 facing the light emitting element 102, so as to ensure the installation position and installation stability of the polarizer 104. More particularly, the polarizer 104 can be directly disposed on the cover 124, so that the polarizer 104 is supported by the cover 124, and the polarizer 104 and the cover 124 can be designed as a whole, thereby reducing the thickness of the polarizer 104 and further realizing the light and thin design of the optical element. Specifically, the cover 124 is a top wall of the component housing.
In a specific application, the polarizer 104 may be formed by first depositing a layer of metal on an end surface of the cover 124 facing the light emitting element 102, then coating an imprint resist, and then performing nanoimprint and etching.
As a possible embodiment, as shown in fig. 3, 4 and 5, the polarizing member 104 is a polarizing layer. And the thickness of the polarizing layer is L, and L is more than or equal to 10nm and less than or equal to 1 um. That is, in the embodiment of the present application, the polarizing layer is directly disposed on the carrier 138 or the cover 124 of the device housing, and the polarizing plate is attached to the carrier 138 or the cover 124 (the carrier 138 is the aforementioned encapsulation layer 126 or the touch layer 128). Therefore, the thickness of the polarizing layer in the embodiment of the present application can reach a nanometer level, and compared with a polarizing film or a liquid crystal cell used in the related art, the embodiment of the present application greatly reduces the thickness of the polarizing piece 104, realizes the light and thin design of an optical element, and conforms to the light and thin technical trend of current smart phones and other electronic devices.
Specifically, the thickness L of the polarizing layer may be 10nm, 20nm, 30nm, 50nm, 70nm, 100nm, 200nm, 300nm, 400nm, 500nm, or the like, which is not limited herein. However, no matter what the specific value of the thickness L of the polarizing layer is, the nanoscale thickness of the polarizer can be realized, and compared with the related art, the thickness of the polarizing layer is greatly reduced, so that the light and thin design of the optical element is realized (the thickness of the polarizing plate or the liquid crystal box in the related art is about 100 um).
As one possible embodiment, as shown in fig. 3, 4 and 5, the light emitting member 102 includes a plurality of display units (a first display unit 106 and a second display unit 108), and any one of the display units includes a plurality of pixel portions (a first pixel portion 114, a second pixel portion 116 and a third pixel portion 118); the polarizer 104 includes a plurality of polarizers (a first polarizer 110 and a second polarizer 112) respectively covering the plurality of pixel portions.
In particular, as shown in fig. 3, 4 and 5, the light emitting member 102 includes a plurality of display units, each of which has a plurality of pixel portions therein, and the plurality of pixel portions can emit light of different colors, so that a variegated light effect is formed by the plurality of display units; the polarizing piece 104 comprises a plurality of polarizing parts, the polarizing parts respectively cover the plurality of pixel parts, the pixel level setting of the polarizing parts is realized, the polarizing parts enable light emitted by the pixels to be emitted after polarizing, and then the display units are matched with one another, so that the naked eye 3D visual effect is realized. In addition, the plurality of polarizing parts can be correspondingly designed and matched according to different shapes and arrangement modes of the plurality of pixel parts, so that the flexibility of the optical element is improved.
In particular, as shown in fig. 1 and 2, the light emitted from each display unit 204' in the related art can only be emitted into one eye of the user, which causes the pixel density in the horizontal and vertical directions to be inconsistent, and the maximum pixel density in the vertical direction is half of the pixel density in the horizontal direction, thereby forming the display effect of stripe phase difference
In particular, since the polarization portions in the embodiments of the present application are designed corresponding to the pixel portions, a plurality of pixel portions are provided in the same display unit, and thus, light emitted from different pixel portions in the same display unit has different polarization directions. Therefore, when the optical element is used, light emitted from the same display unit can enter the left eye and the right eye of a user at the same time, the uniform distribution of pixel density is ensured, the display effect of strip-shaped phase difference existing when a right eye diagram is displayed in one line and a left eye diagram is displayed in one line in the related art can be improved, and the visual effect of the user is further improved.
In a specific embodiment, as can be clearly seen from fig. 3, 4 and 5, the light emitted from the first display unit 106 can be simultaneously incident to the left eye and the right eye of the user, and the light emitted from the second display unit 108 can be simultaneously incident to the left eye and the right eye of the user, so as to ensure the uniform distribution of the pixel density.
It should be noted that, taking the first display unit 106 and the second display unit 108 as an example, the inventive concepts of the embodiments of the present application are merely illustrated, and the plurality of display units are not limited to the first display unit 106 and the second display unit 108.
As a possible embodiment, the plurality of light polarizing portions are distributed in one or more rows in the element case, and the polarization angles of two adjacent light polarizing portions are different in any row. Thus, for the same display unit, the light emitted by two adjacent light-emitting parts has different polarization directions, so that the light emitted by the light-emitting parts in the same display unit can be alternately emitted into the left eye and the right eye of a user, and the uniformity of pixels which can be seen by one eye is improved; and a plurality of display element use mutually supporting like this, can make the user obtain even pixel effect, avoided the phase difference that exists among the correlation technique, and then promoted the homogeneity of showing.
In practical applications, as shown in fig. 6, the left eye of the user is disposed with the first polarized lens 134, and the right eye of the user is disposed with the second polarized lens 136, and the polarization angle of the first polarized lens 134 is ensured to be the same as the first polarization angle of the first polarized part 110, and the polarization angle of the second polarized lens 136 is ensured to be the same as the second polarization angle of the second polarized part 112. Thus, the polarized light passing through the first polarizer 110 may be incident on the left eye of the user, and the polarized light passing through the second polarizer 112 may be incident on the right eye of the user, thereby obtaining a 3D visual effect. Because the first polarized light part 110 and the second polarized light part 112 are simultaneously arranged in the first display unit, and the first polarized light part 110 and the second polarized light part 112 are simultaneously arranged in the second display unit, a user can simultaneously observe the light rays emitted by the first display unit and the second display unit, the uniform distribution of pixels is ensured, and the uniform light and shadow effect is ensured.
Specifically, the first polarization angle of the first polarizer 110 may be 45 °, and the second polarization angle of the second polarizer 112 may be 135 °. Like this, 45 polarized lens can be worn to user's left eye, and 135 polarized lens can be worn to user's right eye, and then obtain 3D's visual effect, guaranteed pixel evenly distributed simultaneously.
As one possible embodiment, as shown in fig. 3, 4 and 5, the plurality of pixel portions include a first pixel portion 114, a second pixel portion 116 and a third pixel portion 118 in the same display unit. The first pixel portion 114 can emit red light, the second pixel portion 116 can emit green light, and the third pixel portion 118 can emit blue light. Thus, when the luminous element works, colorful light and shadow effects can be formed through the cooperation of the red light, the green light and the blue light.
Moreover, since the first pixel portion 114, the second pixel portion 116 and the third pixel portion 118 are respectively covered with the polarizing portion, light of different colors emitted from two adjacent display units are mutually mixed, and then through mutual matching among the plurality of display units, the uniform light emitting effect of the light emitting member 102 is ensured, especially, the light quantity of the left eye and the right eye of the user is equal, the light is uniformly distributed, and the uniform light and shadow effect is ensured.
As a possible embodiment, the optical element further comprises an anode layer 120 and a cathode layer 122, as shown in fig. 3, 4 and 5. Wherein the anode layer 120 and the cathode layer 122 are disposed on opposite sides of the light emitting member 102 and cooperate to cause the light emitting member 102 to emit light. Furthermore, the polarizer 104 is disposed between the cathode layer 122 and the cover 124, so that the cover 124 can also protect the polarizer 104.
As a possible embodiment, as shown in fig. 3, 4 and 5, the element housing further includes a substrate 132. The substrate 132 may be made of metal, such as iron, magnesium, aluminum, magnesium-aluminum alloy, and the like, so as to improve the reliability and strength of the substrate 132; the substrate 132 may be made of plastic, rubber, or fiber to improve the flexibility and ductility of the substrate 132. In addition, the cover 124 is a transparent cover.
As a possible implementation manner, as shown in fig. 3, 4 and 5, the optical element further includes a connection layer 130, and the connection layer 130 is connected to the cover 124 and the cathode layer 122, so as to ensure stable connection between the cover 124 and the cathode layer 122.
As one possible implementation manner, the optical element proposed in the embodiment of the present application is an OLED (Organic Light-Emitting Diode display, Organic Light-Emitting semiconductor).
As shown in fig. 3, 4 and 5, in the embodiment of the present application, the polarizer 104 is disposed inside the optical element, and the polarizer 104 is disposed by relying on the carrier 138 or the cover 124 (the carrier 138 may be the encapsulation layer 126, the touch layer 128, etc.), and a target thickness of the polarizer 104 may be as low as about 30nm, which greatly reduces the thickness of the optical element compared to a polarizer or a liquid crystal cell in the related art (the polarizer or the liquid crystal cell exists independently, and the thickness is generally about 100 um).
In addition, the pixel part in the embodiment of the application can adopt a nanoimprint technology, so that a pixel-level polarizing part can be realized, the pixel-level polarizing part can just correspond to the pixel part in the display unit, and the display effect of the strip-shaped phase difference plate polarizing plate formed by displaying the right eye diagram in one line and the left eye diagram in one line in the related technology can be improved. In addition, for the pixel parts arranged in other shapes, the design and matching of the polarization unit can be carried out according to the shape of the display unit.
The first embodiment is as follows: as shown in fig. 3, the light emitting member includes the light emitting member 102, an anode layer 120, a cathode layer 122, a cover 124, an encapsulation layer 126, a touch layer 128, a connection layer 130, and a substrate 132. Wherein the first pixel portion 114 and the second pixel portion 116 of the polarizer 104 are integrally disposed under the encapsulation layer 126; this integration can be achieved by way of a post-nanoimprint etch. After light is emitted from the display unit, the light passes through the second pixel portion 116 and the third pixel portion 118, and then passes through the connecting layer 130 and the cover 124 to irradiate the first polarized lens 134 and the second polarized lens 136; the light passing through the first polarized lens 134 is incident to the left eye, and the light passing through the second polarized lens 136 is incident to the right eye, and since different parallax images are played by different polarized pixels, a 3D effect is generated.
The second embodiment is as follows: as shown in fig. 4, the light emitting member includes the light emitting member 102, an anode layer 120, a cathode layer 122, a cover 124, an encapsulation layer 126, a touch layer 128, a connection layer 130, and a substrate 132. The first pixel portion 114 and the second pixel portion 116 of the polarizer 104 are integrally disposed above the touch layer 128; the integration can be achieved by first depositing a layer of metal on the passivation layer (SixNy) of the touch layer 128, then coating the imprint resist, and then nanoimprinting and etching. After light is emitted from the display unit, the light passes through the second pixel portion 116 and the third pixel portion 118, and then passes through the connecting layer 130 and the cover 124 to irradiate the first polarized lens 134 and the second polarized lens 136; the light passing through the first polarized lens 134 is incident to the left eye, and the light passing through the second polarized lens 136 is incident to the right eye, and since different parallax images are played by different polarized pixels, a 3D effect is generated.
The third concrete implementation mode: as shown in fig. 5, the light emitting member includes the light emitting member 102, an anode layer 120, a cathode layer 122, a cover 124, an encapsulation layer 126, a touch layer 128, a connection layer 130, and a substrate 132. Wherein, the first pixel portion 114 and the second pixel portion 116 of the polarizer 104 are integrally disposed under the cover 124; the integration can be achieved by first depositing a layer of metal under the cover 124, then coating the imprint resist, and then nanoimprinting and etching. After light is emitted from the display unit, the light passes through the second pixel portion 116 and the third pixel portion 118, and then passes through the connecting layer 130 and the cover 124 to irradiate the first polarized lens 134 and the second polarized lens 136; the light passing through the first polarized lens 134 is incident to the left eye, and the light passing through the second polarized lens 136 is incident to the right eye, and since different parallax images are played by different polarized pixels, a 3D effect is generated.
As shown in fig. 6, in the embodiment of the present application, the specific structure and polarization principle of the polarizer 104 are as follows: the method includes the steps of plating a layer of complete metal on the upper layer or the lower layer of the carrier 138, then coating the stamping glue, then performing nanoimprint and etching, and then performing the second pixel part 116 and the third pixel part 118 by means of etching after nanoimprint, wherein black lines represent metal conductive wire grids, metal of white parts is etched away, and the distance between the conductive wire grids is smaller than the wavelength of visible light (400nm to 760 nm). The light vibration directions generated by the pixel parts are uniformly distributed along all directions, when the light vibration directions pass through the metal conductive wire grids, the vibration of light wave electric vectors in the direction of the metal wire can be absorbed by the metal wire grids, the electric vectors perpendicular to the direction of the metal wire grids can pass through, only photons along the longitudinal direction of the lead are absorbed, and transverse photons are not absorbed, so that linearly polarized light is obtained.
In a specific embodiment, as shown in fig. 6, for example, a first pixel portion 114 and a second pixel portion 116 in the same display unit are covered with a first polarizer portion 110 (the wire grid direction is 135 °, and the polarization direction of light emitted therethrough is 45 °) above the first pixel portion 114, and a second polarizer portion 112 (the wire grid direction is 45 °, and the polarization direction of light emitted therethrough is 135 °) above the second pixel portion 116. In the same display unit, the light emitted from the first polarizer 110 can pass through the first polarized lens 134 (with a polarization direction of 45 °) and enter the left eye; the light emitted from the first polarizing part 110 can be incident to the right eye through the second polarizing lens 136 (with a polarization direction of 135 °), and a 3D effect is achieved.
In fig. 6, the left side indicates light emitted from the first pixel portion 114, and the right side indicates light emitted from the second pixel portion 116.
The polarizer 104 is integrated inside the optical element (the lower surface of the packaging layer 126), the thickness of the polarizer 104 can be as low as 30nm, and compared with the thickness of about 100um which is increased by an external polarizer on the upper end of the optical element in the prior art, the polarizer has great technical advantages.
In the embodiment of the present application, the first polarizing part 110 and the second polarizing part 112 may adopt a nanoimprint technology to implement a pixel-level polarizing unit, which may improve the display effect of a strip-shaped retardation film polarizer formed by displaying a right eye diagram in one line and a left eye diagram in one line in the prior art; in addition, for pixels arranged in other shapes, the design and matching of the polarizing unit can be performed according to the shape of the display unit.
