Wherein the wearable device may be smart glasses, e.g., contact lenses, ordinary glasses, and the like. The following description will be made in detail by taking a smart contact lens as an example.
Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of a wearable electronic device according to an embodiment of the present application, and fig. 2 is a schematic structural diagram of a first decomposition of the wearable electronic device shown in fig. 1. The wearable electronic device 10 includes a contact lens 100 and a display device 300.
The contact lens 100 has a convex surface, and the contact lens 100 can be matched with an eyeball of a human body, so that the lens body 100 can be attached to the eyeball of the human body, thereby wearing the wearable electronic device 10 on the eye of the human body.
The contact lens 100 may be made of hard material, such as polymethyl methacrylate (PMMA), commonly known as plexiglass, or soft material, such as polymethyl methacrylate, having a lens body diameter of about 8.0-11 mm and a thickness of about 0.1-0.8 mm. The soft material adopts poly (2 hydroxymethacrylate) HEMA.
The contact lens 100 may include a first lens and a second lens, wherein the first lens may be a left lens and the second lens may be a right lens, and the left lens is adapted to the left eye of the user and the right lens is adapted to the right eye of the user. It is understood that the first lens may be a right lens and the second lens may be a left lens.
It should be noted that the contact lens 100 may be a cosmetic pupil lens or a vision correction lens, that is, the contact lens 100 may be a flat mirror for wearing by users with normal vision, and the contact lens 100 may be a convex mirror for wearing by users with abnormal vision. Wherein the normal vision is 1.0-2.0, and the abnormal vision is lower than 1.0 or higher than 2.0.
The display device 300 is disposed on one side of the contact lens 100, and the display device 300 can be used to display information such as images and text. The display device 300 may be an Organic Light-Emitting Diode (OLED) display device.
The shape of the display device 300 may be the same as the shape of the contact lens 100, for example, the display device 300 may have a convex surface to make the display device 300 better fit on the contact lens 100. The display device 300 may be attached to the contact lens by an adhesive material.

The display device 300 may be located in the middle of the contact lens 100, and the display device 300 may also be located at the edge of the contact lens 100, because the curved surface area of the display device 300 is smaller than that of the contact lens, not only the normal eyesight function of the user may be realized, but also the AR function of the wearable electronic device 10 may be realized.
Referring to fig. 4, fig. 4 is a second schematic view of the contact lens and the display device shown in fig. 2, it can be understood that the size of the display device 300 can be equal to the size of the contact lens 100, that is, the convex surface (curved surface) area of the display device 300 is equal to the convex surface (curved surface) area of the contact lens 100, or alternatively, the display device 300 is coincident with the contact lens 100.
When the size of the display device 300 can be equal to the size of the contact lens 100, the display device 300 has a high light transmittance, which does not affect the normal eyesight function of the user, and can increase the display area of the display device 300 to improve the AR function of the wearable electronic device 10.
The wearable electronic device 10 provided by the embodiment of the application can reduce the size of the wearable electronic device 10 by integrating the display device 300 with the display function on the contact lens 100, so that the wearable electronic device is convenient for a user to carry, and the user experience is improved.

The wearable electronic device 10 further includes an optical filter 500, the optical filter 500 is disposed on the lens body 100, and the optical filter 500 may be a fresnel zone plate, that is, a band-pass optical filter; the Fresnel zone plate has the functions of a converging lens and a diverging lens, and consists of transparent and non-transparent circular rings alternately. The Fresnel zone plate is characterized in that equidistant insections are formed on one side of the Fresnel zone plate, and the insections can achieve the effect of light band pass reflection or refraction in a specified spectral range, so that the focusing function can be realized.
Wherein, one side of the display device 300 facing the optical filter 500 is provided with a tooth socket, and the tooth socket is matched with the tooth pattern of the optical filter 500, so as to realize the mutual connection of the display device 300 and the optical filter 500.

Referring to fig. 6, fig. 6 is a first schematic view of the display device shown in fig. 5. The display device 300 includes a first display area 310 and a second display area 320. The second display area 320 and the first display area 310 are adjacent to each other. The second display area 320 may be disposed around the first display area 310, and the second display area 320 may also be disposed partially around the first display area 310.
The first display area 310 and the second display area 320 are used for displaying images, and the first display area 310 and the second display area 320 may display the same image or different images. When the first display area 310 and the second display area 320 display different screens, the first display area 310 is used to display a function screen, for example, time, date, and the like.
The area of the second display area 320 may be larger than the area of the first display area 310, and the area of the second display area 320 may also be smaller than or equal to the area of the first display area 310.
Wherein, first display area 310 is greater than the luminousness of second display area 320, and external light can kick into through first display area 310, can not influence user's normal eyesight function, moreover, because the luminousness of second display area 320 is greater than the luminousness of first display area 310, can improve display device 300's display effect, improves the AR function.
It should be noted that in the embodiment of the present disclosure, the second display area 320 may serve as a main display area of the display device 300, the first display area 310 may serve as an auxiliary display area of the display device 200, the second display area 320 may be an active matrix driving (AMOLED) display area, and the first display area 310 may be an active matrix driving (AMOLED) display area or a passive matrix driving (PMOLED) display area. Although the display effect of the PMOLED is lower than that of the AMOLED, the PMOLED may be used in the first display region 310 because the area of the first display region 310 is small, the displayed content is also small, and the importance of the displayed content is low because the first display region 310 is located at the edge of the display device 300. The passively-driven first display region 310 only needs one Thin Film Transistor (TFT) for driving, and the number of opaque thin film transistors is very small, so that the light transmittance of the first display region 310 can be greatly improved.
It is to be understood that, in the description of the present application, terms such as "first", "second", and the like are used merely to distinguish similar objects and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated.
The first display area 310 is located in the middle of the display device 300, and the pixel density of the first display area 310 is less than the pixel density of the second display area 320, so that the light transmittance of the first display area 310 can be improved, and the first display area 310 is disposed in the middle position, which does not interfere with the normal visual function of the eyes.

The size of the first pixel 312 is greater than the size of the second pixel 322, for example, the size of the first pixel 312 is four times the size of the second pixel 322, and as the size of the first pixel 312 is greater than the size of the second pixel 322, the number of the first pixels 312 can be reduced on the basis of maintaining the original pixel brightness, and further the pixel density of the first pixel 312 can be reduced, for example, the pixel density of the first pixel 312 is 200ppi, the pixel density of the second pixel 322 is 400ppi, and the light transmittance of the first display region 310 can be improved.
It is understood that the first pixel 312 can be a transparent pixel, and the first pixel 312 is made of a transparent material, for example, transparent Indium Tin Oxide (ITO), which can further improve the light transmittance of the first display region 310.
Please refer to fig. 8, which is a third schematic diagram of the display apparatus of fig. 5. The display device 300 further includes a display layer and a driving layer, the driving layer being located at a side of the display layer facing the inside of the display device 300. The driving layer includes a plurality of first driving units 314 and a plurality of second driving units 324.
It is understood that the driving unit may adopt one of the driving circuits using 2T1C, 5T1C, 7T1C, etc. For example, the first driving unit 314 may adopt one of 2T1C, 5T1C, and 7T1C, and the second driving unit 324 may adopt one of 2T1C, 5T1C, and 7T 1C. Where T denotes a thin film transistor, and C denotes a capacitance. In order to improve the light transmittance of the first display region 310, the first driving unit 314 disposed in the first display region 310 may be a simpler driving circuit than the second display region 320 and the main driving unit of the first display region 310, for example, the first driving unit 314 includes a smaller number of thin film transistors than the second driving unit 324. For example, the first driving unit 314 may adopt one of 2T1C and 5T1C, and the second driving unit 324 adopts 7T 1C. The number of the opaque tfts in the first driving unit 314 is less, and the portion of the first display region 310 that is opaque is less, so that the transmittance of the first display region 310 can be improved.
The plurality of first driving units 314 are disposed in the first display region 310, and the first driving units 314 are used for driving the first pixels 312, for example, one first driving unit 314 may be electrically connected to one first pixel 312, and one first driving unit 314 may also be connected to a plurality of first pixels 312, for example, two, four, or six.

It is understood that one first driving unit 314 may also drive at least a plurality of parallel-connected first pixels 322, for example, two, four or six, and by driving a plurality of parallel-connected first pixels 312 through one first driving unit 314, the number of first driving units 314 may be reduced, so that the light transmittance of the first display region 310 may be improved.
It is understood that the first driving unit 314 may also be disposed in the second display area 320, for example, the first driving unit 314 may be disposed below the second pixels 322, that is, a projection of the first driving unit 314 in the second display area 320 is located in one second pixel 322.
It is to be understood that, in order to save space in the second display area 320, a plurality of first driving units 314 may also be located below the second pixels 322, for example, two first driving units 314 are located below one second pixel 322, that is, the projection of two first driving units 314 on the second display area 320 is located in one second pixel 322. The light transmittance of the first display area 310 can be improved on the basis of saving the occupied area of the first driving unit 314 in the horizontal direction of the second display area 320, so that the normal visual function of human eyes can be better ensured.

The third display area 330 is used for displaying a screen, and the screen displayed in the third display area 330 may be the same as or different from the first display area 310 and the second display area 320. The third display area 330 may be an active driving (AMOLED) display area.
The third display region 330 includes a third display layer 303, the third display layer 303 includes a plurality of third pixels 332, and the physical structure of the third pixels 332 may be the same as that of the second pixels 322, for example, the size of the third pixels 332 is the same as that of the second pixels 332.
It is understood that the pixel size of the third pixel 332 may be different from the size of the second pixel 322, for example, the pixel size of the third pixel 332 is larger than the size of the second pixel 322, and the pixel density of the third pixel 332 may be reduced, for example, the pixel density of the third pixel 332 is half of the pixel density of the second pixel 322, and since the pixel density of the third pixel 332 in the third display region 330 is smaller, the number of required driving units may be reduced, so that enough space may be reserved for arranging the driving units in the first display region 310, which is helpful for increasing the light transmittance of the first display region 310.
The third display region 330 further includes a plurality of third driving units 334, and the third driving units 334 are configured to drive the third pixels 332, where one third driving unit 334 may drive one third pixel 332, and the third driving unit may also drive a plurality of third pixels 332, for example, two, three, four, and so on.

It is understood that the first driving unit 314 may also be located at a different layer from the third driving unit 334, for example, the first driving unit 314 may be disposed below the third pixels 332, that is, the projection of the first driving unit 314 on the third display area 330 is located in one third pixel 332.
It is to be understood that, in order to save space in the third display area 330, a plurality of first driving units 314 may also be located below the third pixels 332, for example, two first driving units 314 are located below one third pixel 332, that is, the projections of the two first driving units 314 on the third display area 330 are located in one third pixel 332. The light transmittance of the first display region 310 can be improved on the basis of saving the occupied area of the first driving unit 314 in the horizontal direction of the third display region 330, so that the normal visual function of human eyes can be better ensured.
It can be understood that a plurality of the first driving units 314 may also be partially disposed in the second display area 320, and another portion is disposed in the third display area 330, so as to save the occupied space of the first driving units 314 in the horizontal direction of the third display area 330.

The non-display area 340 is located at the periphery of the illustrated second display area 320, and the non-display area 340 does not display information. The plurality of first driving units 314 of the first display region 310 may be partially located in the second display region 320, and another portion may be located in the non-display region 340, so that on one hand, the light transmittance of the first display region 310 may be improved, and on the other hand, the normal visual function of human eyes may not be affected.
It can be understood that the plurality of first driving units 314 and the plurality of third driving units 334 may be all located in the non-display area 340, and since there is no opaque driving circuit in the first display area 310 and the third display area 330, the light transmittance of the first display area 310 and the third display area 330 may be improved, and the area of the light-transmitting area may be enlarged, so as to improve the range of the normal visual function of human eyes.
It is understood that the plurality of first driving units 314 may be entirely located in the second display region 320, and the plurality of third driving units 334 may be entirely located in the non-display region 340.

Specifically, the first driving unit 314 is used for driving a plurality of first pixels 312 connected in parallel, the second driving unit 324 is used for driving a plurality of second pixels 322 connected in parallel, and the third driving unit 334 is used for driving a plurality of third pixels 332 connected in parallel, so as to reduce the number of the first driving unit 314, the second driving unit 324, and the third driving unit 334, and thus the occupied space of the first driving unit 314, the second driving unit 324, and the third driving unit 334 in the non-display area 340 can be saved.
The display device 300 further includes a plurality of first driving lines disposed in the first display area 310, a plurality of second driving lines disposed in the second display area 320, and a plurality of third driving lines disposed in the third display area 330, wherein the first driving circuit 314 is electrically connected to the first pixel 312 through the first driving lines, the second driving circuit 324 is electrically connected to the second pixel 322 through the second driving lines, and the third driving circuit 334 is electrically connected to the third pixel 332 through the third driving lines.

Referring to fig. 5 again, the shape of the first pixel 312 may be circular or elliptical, the first pixel 312 may block light with the first wavelength, and the diameter of the cross section of the first pixel 312 may be a non-integral multiple of half of the first wavelength.
It is understood that the first pixel 312 may block light within a certain wavelength band, and the light of the first wavelength may be a light within the certain wavelength band. For example, the first pixel 312 may block light in the visible light band (380 nm to 750 nm band), so that the first pixel 312 may block red light of 700 nm, or blue light of 480 nm, or green light of 520 nm. At this time, the cross-sectional diameter of the first pixel 312 may be a non-integral multiple of one half of any wavelength in the entire wavelength band, that is, the cross-sectional diameter of the first pixel 312 may avoid one half of the integral multiple of any wavelength in the entire wavelength band.
It is understood that when the shape of the first pixels 312 is circular, the non-integer multiple of one half of the first wavelength means that the diameter of the cross section of the first pixels 312 is not an integer multiple of one half of the first wavelength, i.e. the diameter D ≠ n · 1/2 · λ (first wavelength), n being a positive integer.
It is understood that when the cross-section of the first pixel 312 is circular, that is, the first pixel 312 is a spherical pixel, the diameter between any two points passing through the center on the surface of the first pixel 312 can be a non-integer multiple of half of the first wavelength. The center of the first pixel 312 may be the center of the circular cross-section of the first pixel 312.
It is understood that when the cross-section of the first pixel 312 is elliptical, i.e., the first pixel 312 is an ellipsoidal pixel, the diameter between any two points on the surface of the first pixel 312 passing through the center can also be a non-integer multiple of half the first wavelength. The center of the first pixel 312 may be the intersection of the upper major axis and the half axis of the elliptical cross-section of the first pixel 312.
Based on the optical principle, when light outside the display device 300 passes through the first pixel 312, since the transmittance of the first pixel 312 is different from the transmittance of the air and the pixel spacing region, the first pixel 312 is an obstacle relative to the air and the pixel spacing region, and the light deviates from the original straight propagation track when passing through the first pixel 312 of the obstacle, thereby forming a diffraction phenomenon. In the display device 300 of the embodiment of the application, the cross section of the first pixel 312 is a circular or elliptical pixel, and when the first pixel 312 blocks the light with the first wavelength, because the diameter of the cross section of the first pixel 312 is a non-integral multiple of half of the first wavelength, the energy can be more concentrated in the primary diffraction fringes, the energy of each secondary diffraction fringe is lower, and each secondary diffraction fringe is less, so that the diffraction phenomenon can be reduced.
To further mitigate the diffraction interference, please refer to fig. 12, fig. 12 is a first distribution diagram of the first pixel shown in fig. 6. In the display device 300 of the embodiment of the application, each first pixel 312 may include the main body portion 3121 and the edge portion 3122 connected to each other. The cross section of the main body portion 3121 may be circular or elliptical. The rim portion 3121 may be approximately annular in cross-section, which may include an outer contour that surrounds and conforms to the outer periphery of the body portion 3121 and an inner contour, which may be a closed circular or elliptical curve; the outer profile may include a plurality of curves of different curvatures that may be interconnected to form a closed curve around the body portion 3121.
It will be appreciated that the plurality of curves of different curvature may form an irregular closed curve around the body portion 3121. The irregular closed curve can mean that the curve is not a regular polygon such as a regular triangle, a regular quadrangle and the like; the irregular closed curve is not common triangle, square, rectangle or parallelogram; the irregular closed curve is not regular round or oval; the irregular curve is not a curve formed by connecting a plurality of identical arcs.
It is to be understood that, as shown in fig. 12, the edge portion 3122 formed of a plurality of curved lines having different curvatures may form a plurality of protrusions, each of which may extend from an outer edge of the main body portion 3121 toward a direction away from the main body portion 3121. At this time, the outer circumference of the first pixel 312 may include a plurality of protrusions.
It is understood that the number of the protrusions may be about 20 to 30, in this case, the outer circumference of the edge portion 3122 may include 20 to 30 curves connected to each other first, and the outer circumference of the first pixel 312 may have an irregular curve.
In the display device 300 of the embodiment of the application, when the first pixel 3122 includes the edge portion 3122 formed by the curves with different curvatures, the first pixel 3122 is affected by the curves with different curvatures, and when the external light passes through the edge portion 3122 of the first pixel 312, diffraction phenomena formed at different positions on the edge portion 3122 are mutually offset, so that formation of diffraction fringes can be reduced, and diffraction interference can be reduced.
Wherein, when the outer contour of the edge portion 3122 includes a plurality of curves, the curvature of any two adjacent curves may be different. Furthermore, when the light passes through any two adjacent curves, the formed diffraction phenomena are more easily counteracted, so that the probability of diffraction when the light passes through the whole edge portion 3122 is greatly reduced, and the diffraction phenomena can be greatly reduced.
Referring to fig. 13, fig. 13 is a second distribution diagram of the first pixel shown in fig. 6. In the display device 300 of the embodiment of the application, the first display area 310 may include a plurality of first pixels 312 arranged at intervals, that is, the plurality of first pixels 312 are arranged at intervals in the first display layer. Here, the diameter d of the cross section of the first pixel 312 may not be one half of the distance a between two adjacent first pixels 312, that is, the diameter of the cross section of the first pixel 312 may be greater than or less than one half of the distance a between two adjacent first pixels 312.
It is understood that the diameter of the cross section of the first pixel 312 can be referred to the above description, and is not described herein.
It is understood that, as shown in fig. 13, the distance a between two adjacent first pixels 312 may be a distance between two points located on the edges of the two first pixels 312, wherein a connecting line of the two points on the edges of the two first pixels 312 passes through the centers of the two first pixels 312 respectively.
It is understood that the two first pixels 312 of the embodiment of the present application may be both elliptical pixels, both circular pixels, and both circular pixels and elliptical pixels. Of course, the two first pixels 312 in the embodiment of the present application may also have other shapes, and the embodiment of the present application does not limit the specific shape thereof.
It can be understood that it is assumed thatThe refractive index of the inter-pixel region of the first display region 210 is n1Thickness d1The refractive index of the first pixel 312 is n2Thickness d2The distance between two adjacent first pixels 312 is a, the diameter of the first pixel 312 is d, and the distance between the light source and the first display region 310 is n0Then, the transmittance function of the light passing through the first display area 310 can be expressed as:
Figure BDA0002724458700000121
different diffraction patterns can be obtained by changing the values of a and d, respectively. For example, please refer to fig. 14 to 16, wherein fig. 14 is a first diffraction pattern of the first display area of the embodiment of the present application, fig. 15 is a second diffraction pattern of the first display area of the embodiment of the present application, and fig. 16 is a third diffraction pattern of the first display area of the embodiment of the present application. In fig. 14 to 16, the diffraction intensity envelope of the first display area 310 is shown on the left, and the diffraction order distribution of the first display area 310 is shown on the right.
In fig. 14, the pitch a of two adjacent first pixels 312 is 18 micrometers, and the diameter d of the first pixels 312 is 23 micrometers. In fig. 10, the pitch a of two adjacent first pixels 312 is 18 micrometers, and the diameter d of the first pixels 312 is 33 micrometers. In fig. 14, the pitch a of two adjacent first pixels 312 is 18 micrometers, and the diameter d of the first pixels 312 is 63 micrometers.
As can be seen from comparing fig. 14 to 16, the diffraction order spacing and d are in inverse proportion, and the diffraction order spacing is gradually reduced as d increases, and the ± 1 st order diffraction light intensity is strongest when the ratio of a to d is close to 0.5 d.
Based on this, in the display device 300 of the embodiment of the present application, the diameter of the cross section of the first pixel 312 may not be half of the distance a between two adjacent first pixels 312, and when light passes through the first display region 310, the intensity of secondary diffraction light may be weak, so that diffraction may be reduced.
