Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to German application 10 2022 116 210.9, filed on June 29, 2022, the entire contents of which are incorporated herein by reference. Technical Field

[0003] Various aspects of the present disclosure generally relate to organic light emitting diodes (OLEDs) and light projection through light transmissive regions between OLEDs. Background Art

[0004] OLED-based displays are widely used in a variety of portable electronic devices (e.g., smart phones, tablet computers, etc.). Many such devices perform various 3D sensing operations, in which the device projects a pattern onto an object, captures an image of the object with the projected pattern, and generates 3D information about the object based at least on a distortion of the projected pattern on the surface of the object. For example, many smart phones and tablet computers include facial recognition capabilities, in which a pattern (e.g., in a non-visible light spectrum) is projected onto a user's face, and the corresponding pattern distortion allows depth information to be generated. Because the 3D information (e.g., depth information) associated with a user's face may be unique to that user, such a facial recognition process can enhance security by allowing authentication of the user.

[0005] Typically, a user device utilizing such pattern recognition technology (e.g., facial recognition technology) places its light source for projecting its pattern in a designated area of ​​the display adjacent to the OLED pixels. In many devices, the display may include a recessed (e.g., cutout) area to accommodate the light source for projecting the image. This is particularly useful in Figure 1 Depicted in Figure 1 A smartphone is shown in which the available area of ​​the display is depicted as 102, and the display includes a cutout 104 in which a projector 106 is placed. This results in reduced functionality for the overall display size and can reduce user satisfaction.

[0006] Projection through OLED displays (e.g. projection of patterns for 3D recognition) would eliminate the need for Figure 1 The need for cutout 104 is depicted; however, many aspects of the OLED display are functionally opaque to block most of the light projected from behind the OLED display.

[0022] The following detailed description refers to the accompanying drawings that show, by way of illustration, exemplary details and embodiments in which aspects of the disclosure may be practiced.

[0023] The word “exemplary” is used herein to mean “serving as an example, instance, or illustration.” Any implementation or design described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other implementations or designs.

[0024] Throughout the drawings, it should be noted that unless otherwise described, the same reference numbers are used to depict the same or similar elements, features, and structures.

[0025] The phrases "at least one" and "one or more" may be understood to include numerical quantities greater than or equal to one (e.g., one, two, three, four, ... etc.). Phrases with respect to a group of elements: "at least one" may be used herein to mean at least one element selected from the group consisting of the elements. For example, the phrase "at least one" with respect to a group of elements may be used herein to mean a selection from: one of the listed elements, a plurality of the listed elements, a plurality of individually listed elements, or a plurality of a plurality of individually listed elements.

[0026] The words "plurality" and "multiple" in the specification and claims clearly refer to quantities greater than one. Therefore, any phrase that explicitly refers to the aforementioned words (e.g., "plurality [elements]," "multiple [elements]") referring to quantities of elements clearly refers to more than one of the elements. For example, the phrase "plurality" can be understood to include numerical quantities greater than or equal to two (e.g., two, three, four, five..., etc.).

[0027] The phrases "group", "set", "collection", "series", "sequence", "grouping", etc. in the specification and claims, if any, refer to a quantity equal to or greater than one, i.e., one or more. The terms "proper subset", "reduced subset", and "smaller subset" refer to a subset of a set that is not equal to the set, illustratively, to a subset of a set that contains fewer elements than the set.

[0028] The term "data" as used herein may be understood to include information in any suitable analog or digital form, for example, information provided as a file, a portion of a file, a set of files, a signal or stream, a portion of a signal or stream, a group of signals or streams, etc. In addition, the term "data" may also be used to represent a reference to information, for example, a reference to information in the form of a pointer. However, the term "data" is not limited to the above examples, and may take various forms and represent any information understood in the art.

[0029] For example, the term "processor" or "controller" used herein may be understood as any kind of technical entity that enables processing of data. Data may be processed according to one or more specific functions performed by a processor or controller. In addition, a processor or controller used herein may be understood as any kind of circuit, for example, any kind of analog circuit or digital circuit. A processor or controller may therefore be or include an analog circuit, a digital circuit, a mixed signal circuit, a logic circuit, a processor, a microprocessor, a central processing unit (CPU), a graphics processing unit (GPU), a digital signal processor (DSP), a field programmable gate array (FPGA), an integrated circuit, an application specific integrated circuit (ASIC), etc., or any combination thereof. Any other type of implementation of each function described in more detail below may also be understood as a processor, a controller or a logic circuit. It should be understood that any two (or more) of the processors, controllers or logic circuits described in detail herein may be implemented as a single entity with equivalent functionality, etc., and conversely, any single processor, controller or logic circuit described in detail herein may be implemented as two (or more) separate entities with equivalent functionality, etc.

[0030] Various aspects of the present disclosure relate to organic light emitting diodes (OLEDs). An OLED is a light emitting diode (LED) that uses an organic compound to emit light in an electroluminescent process. Each OLED element may be located between two electrodes that may provide a current or voltage to drive the OLED and excite the organic compound to emit light. An OLED may be formed using any of a variety of organic compounds. In some implementations, some of the OLED structures may be transparent. OLEDs are generally known in the art, and the principles and methods disclosed herein are believed to be able to be implemented using most or all OLED configurations.

[0031] Figure 2A portion of a display is depicted, which includes a plurality of first light sources 202 arranged in a first zone 204. The first zone 204 can be understood as a plane along the x-axis and the y-axis. Alternatively or additionally, the first zone 204 can be understood as also including a height or thickness along the z-axis. The display also includes a plurality of lenses 206, which are arranged in a second zone 208 above the first zone 204. Similar to the first zone 204, the second zone 208 can be understood as a plane along the x-axis and the y-axis. Alternatively or additionally, the second zone 208 can be understood as also including a height or thickness along the z-axis. The second zone 208 can be parallel to or substantially parallel to the first zone 204. The distance between the plurality of first light sources 202 and the lens 206 (or the distance between the first zone 204 and the second zone 208, respectively) can be selected or determined to ensure that a far-field high contrast pattern is formed (e.g., a dot pattern is generated as needed without using a second MLA). The display may also include a plurality of opaque regions 210 and a plurality of light-transmitting regions 212, which are arranged in a third region 214 above the second region 208. The light-transmitting region may include a region where an OLED structure / lattice of an organic compound is not present (e.g., a gap between regions of an organic compound), a region with a transparent electrode, or other region. The plurality of opaque regions may include: regions including organic compounds, opaque electrodes, and the like. The third region 214 may also be along the x-axis and the y-axis with an optional z-axis height. The third region 214 may be parallel or substantially parallel to the first region 204 and the second region 208. Each of the plurality of first light sources 202 may be configured to direct light to a lens in the plurality of lenses 206. Each of the plurality of lenses 206 may be configured to receive light from a first light source in the plurality of first light sources 202 and direct the light through a light-transmitting region in the plurality of light-transmitting regions 212.

[0032] Figure 3 A pixel structure of a portion of a display is depicted, including an OLED layer and a thin film transistor (TFT) layer. The display may include a plurality of pixels 302 (which may also be referred to herein as a "second light source"), wherein each pixel 302 includes at least a pixel light blocking electrode 304, one or more interlayer materials 306, and a TFT light blocking electrode 308. The TFT region may include a photosensitive region 310. Any of the pixel light blocking electrodes and / or the TFT light blocking electrodes may be covered by light absorbing materials 312a, 312b.

[0033] Figure 4An additional representation of a pixel structure is depicted. In this figure, a pixel includes a TFT plane 402, a pixel electrode plane 404, and a best focus plane 406 between the TFT plane 402 and the pixel electrode plane 404. Light from the first light source 202 passes through one or more lenses 206 of the lens array and is focused so that its focus is at the best focus plane 406, and therefore its beam is focused narrowly enough so that most or all of the beam passes through the opening of the TFT plane 402 and also passes through the opening in the pixel electrode plane 404. In other words, the opening in the TFT plane 402 may not have the same size as the opening in the pixel electrode plane 404 (e.g., may have different widths and / or lengths, such as along the x-axis and / or y-axis). The relative height of the best focus plane 406 (e.g., the distance of the light focusing plane from the TFT plane and / or the distance of the light focusing plane from the pixel electrode plane) can be selected to ensure that the maximum light travels through both the opening in the TFT plane 402 and the opening in the pixel electrode plane 404. For example, the relative height of the light focusing plane 406 may be controlled by the distance between the first light source 202 and the one or more lenses 206 .

[0034] Figure 5 An optional aspect of the present disclosure is depicted, in which an optical via 502 is placed along the z-axis (e.g., substantially perpendicular to the pixel electrode plane 404). The optical via may be or include an optical waveguide configured to guide light through one or more layers of a device (e.g., a semiconductor or integrated circuit). In this way, the lens 206 can focus light from the first light source 202 onto the receiving area of ​​the optical via 502, thereby causing the light to be guided through the optical via and to exit from the opposite side of the optical via. In this way, light can be conveniently guided through the pixel electrode plane 404. Alternatively or additionally, the optical via may not be a waveguide itself, but may be or include a high optical quality material. In this configuration, the high optical quality material may extend from the TFT plane 402 through the pixel electrode plane 404.

[0035] Figure 6 An optional configuration according to one aspect of the present disclosure is depicted, wherein the plurality of lenses 206 is a first plurality of lenses, and wherein the display includes a second plurality of lenses 602. The second plurality of lenses 602 may be or include, for example, a lens array (e.g., a microlens array). Depending on the distance between the second plurality of lenses 602 and the light focusing plane 406, each lens in the second plurality of lenses 602 may be configured to receive light from one or more lenses in the first plurality of lenses 206. In this configuration, the first plurality of lenses 206 may form light from the first light source 202 into a plane of optimal focus, which may increase the overall transmittance through the third region 214. As described above with respect to Figure 2As described above, the distance between the light focal plane 406 and the second plurality of lenses 602 may be selected to ensure that a far field pattern is formed or controlled.

[0036] Figure 7 An optional configuration according to one aspect of the present disclosure is depicted in which light passing through the third zone 214 is received in one or more optical through-holes 502 and passes through one or more optical relays. In addition to the dot projectors otherwise disclosed herein, this aspect of the present disclosure may relate to lighting, such as behind-the-display flood lighting, which may not require the plurality of lenses 206 to be a particular distance from the source plane (e.g., the first zone 204). That is, the illumination field may be changed by changing the focal plane distance and position of the first light source 202 and the plurality of lenses 206. In this configuration, the first plurality of lenses 206 may be located in close proximity to the source plane (e.g., the first zone 204), where, for example, the first plurality of lenses 206 are located directly on the first light source 202, or very close to the first light source 202. In configurations where there is a gap between the first light source 202 and the first plurality of lenses 206, the gap may be configured such that only light from one first light source 202 enters a lens of the plurality of lenses 206. This configuration may have the advantage of resulting in a particularly compact design. Alternatively or additionally, a compact form factor may also be achieved by limiting the length of the optical vias such that they are limited to the length required for light from the first light source to propagate through the pixel electrode.

[0037] Figure 8 An optional configuration according to one aspect of the present disclosure is depicted in which the light source is configured for flood lighting. In this configuration and after the light from the plurality of lenses 206 passes through the third zone 214, the light can be transmitted via a plurality of high numerical aperture (NA) optical vias (e.g., optical waveguides) 802. These high NA optical vias 802 can be configured to transmit most or all of the light received from the first end to the second end, and transmit the light, for example, by means of total internal reflection. The high NA optical vias 802 can optionally be coated, for example, to increase internal reflection.

[0038] Fig. 9A display configured as a heterogeneous display is depicted. In this configuration, the heterogeneous display includes a first resolution region 902 and a second resolution region 904, wherein the second resolution region 904 has a lower display resolution than the first resolution region 902. Display technology is rapidly advancing, and the spacing of display pixels and the amount of light-transmissive regions (e.g., 212, not shown in this image) adjacent to the pixels can vary significantly, such as between different resolutions, display production and manufacturing precisions. For certain high resolution displays, it is contemplated that the amount of light that can be focused and directed through the light-transmissive regions between pixels as described herein may not be sufficient for a particular purpose. In such a case, or in other cases where desired, it may be beneficial to implement a display having two or more resolution regions. In Fig. 9 , wherein a high-resolution region 902 occupies some or most of the display, but a low-resolution region (a region having a lower resolution than the high-resolution region) 904 is used for portions of the display through which light generated by a first light source 202 (not depicted in this figure) is directed in accordance with the principles and methods disclosed herein. That is, in many configurations where it is desirable or advantageous to direct light from the first light source 202 through a third region 214, it may only be necessary to do so in a small portion of the display. Thus, a small portion of the display may be dedicated to this purpose and may be given a lower resolution than the rest of the display, wherein the lower resolution has a larger spacing between pixels and, therefore, a larger light-transmissive region 212 through which light may be directed. This may result in a greater amount of light being directed through a pixel using the principles and methods disclosed herein and / or looser manufacturing tolerances.

[0039] Fig.10 A method of manufacturing a display is described, comprising: providing a plurality of first light sources 1002 arranged in a first zone; providing a plurality of lenses 1004 arranged in a second zone above the first zone; providing a plurality of opaque areas and a plurality of light-transmitting areas 1006 arranged in a third zone above the second zone; wherein each of the plurality of first light sources is configured to direct light onto a lens of the plurality of lenses 1008; and wherein each of the plurality of lenses is configured to receive light from a first light source of the plurality of first light sources and direct the light through a light-transmitting area of ​​the plurality of light-transmitting areas 1010.

[0040] According to one aspect of the present disclosure, the structure disclosed herein can be configured as a display 102, wherein the display 102 includes a plurality of first light sources 202 arranged in a first zone 204. The plurality of first light sources 202 can be or include any light generating element. According to one aspect of the present disclosure, the plurality of first light sources 202 can be vertical cavity surface emitting lasers.

[0041] The display may also include a plurality of lenses 206, which may be arranged in a second zone 208 above the first zone 204. The plurality of lenses 206 may be configured to receive light from the plurality of first light sources 202 and direct the light to the third zone 214. The plurality of lenses 206 may optionally be a microlens array. The microlens array may include a plurality of microlenses arranged in a periodic pattern (e.g., a square pattern, a hexagonal pattern, etc.). The microlens array may be configured to have a particularly small spacing between the microlenses. According to one aspect of the present disclosure, the spacing may optionally be less than 500 μm; the spacing may optionally be less than 200 μm; the spacing may optionally be less than 100 μm; the spacing may optionally be less than 50 μm; or, the spacing may optionally be less than 10 μm.

[0042] Each lens in the plurality of lenses 206 may be configured to receive light from one or more than one of the first light sources 202. That is, in some cases, it may be desirable to configure the plurality of lenses 206 such that they receive light from multiple light sources in the plurality of first light sources 202. Alternatively, the plurality of lenses 206 may be configured such that each lens in the plurality of lenses 206 receives light from a single first light source in the plurality of first light sources 202.

[0043] The display may include a plurality of opaque regions 210 and a plurality of light-transmitting regions 212, which are arranged in a third region 214 above the second region 208. The plurality of opaque regions 210 and the plurality of light-transmitting regions 212 may be opaque regions and light-transmitting regions of a plurality of pixels 302. In this manner, the opaque regions 210 may correspond to one or more light-emitting diodes (e.g., electrodes, organic compounds, semiconductors, etc.) of the pixel, and the light-transmitting regions 212 may correspond to spaces between the light-emitting diodes.

[0044] The light emitting diode may typically be an organic light emitting diode. Alternatively, in some configurations, a plurality of inorganic light emitting diodes may be optionally used to implement the concepts disclosed herein. The principles and methods disclosed herein should be understood to be applicable to both organic light emitting diodes and inorganic light emitting diodes.

[0045] Each of the plurality of lenses 206 may be configured to receive light from at least one of the plurality of first light sources 202 and direct the light through a light-transmitting region of the plurality of light-transmitting regions 212 within the third zone 214. The plurality of light-transmitting regions 212 may be regions between the second light sources 302. Each of the plurality of lenses 206 may have a refractive property and a distance to a light-transmitting region of the plurality of light-transmitting regions 212, such that each of the plurality of lenses 206 refracts light from a first light source of the plurality of first light sources 202 to have a focus in a light-transmitting region 212 of the plurality of light-transmitting regions 212 based on the refractive property and the distance to the light-transmitting region 212.

[0046] The display may further include a controller that may be configured to control the plurality of second light sources 302 to emit an image on the display. The controller may be any one or more processors that may be capable of controlling at least the plurality of second light sources 302.

[0047] The plurality of first light sources 202 may optionally be arranged to project a test pattern onto a surface outside the display. This may be particularly useful when determining three-dimensional information about an object based on an image. Using this technique, a pattern is projected onto an object, and an image of the pattern projected onto the object is taken. Based on the distance between the light source used for projection and the instantaneous portion of the object onto which the pattern is projected, the pattern will become distorted. By analyzing the distortion in the pattern, information about the depth of a given portion of the object relative to the projection source may be obtained. For example, this may be a valuable technique for facial recognition. According to one aspect of the present disclosure, the principles and methods disclosed herein may be used in facial recognition processing.

[0048] The display may optionally include one or more optical through holes. In such a configuration, each of the plurality of optical through holes may be arranged within a light-transmitting region of the plurality of light-transmitting regions. Illustratively, the plurality of second light sources may be arranged along an x-axis and a y-axis, and the optical through holes may be arranged along a z-axis such that the optical through holes are substantially perpendicular to a plane including the second light sources. Each of the plurality of optical through holes may include a first end and a second end opposite the first end. The optical through holes may be configured to receive light emitted from one or more of the first plurality of lenses at their first ends, and to emit light from their second ends.

[0049] Each of the plurality of second light sources may be described by a first side and a second side opposite to the first side. In an implementation where there are a second plurality of lenses, the first side may face the second plurality of lenses. As an alternative description method, the second side may be understood as a side facing the first plurality of lenses. The second side may include a plurality of light absorbing regions surrounding the light-transmitting region, wherein the plurality of light absorbing regions are configured to absorb light from the plurality of first light sources.

[0050] In some configurations, there can be an optional second lens array above the second light source. In this way, the output of the second light source can be collimated by the third set of lenses. The collimated light propagates from the collimating lens above the second light source and reaches the second lens array. In this way, the second lens array acts as a diffuser.

[0051] Additional aspects of the disclosure will be described by way of example.
