- Claim: 1. A display comprising: a display layer including an array, grid or matrix of spaced pixels and an array, grid, or matrix of spaced transmission spaces, wherein each pixel includes a plurality of spaced subpixels and each transmission space is defined by a spacing between: a subset of the spaced pixels, a subset of the spaced subpixels, or some combination of the subset of the spaced pixels and the subset of the spaced subpixels; a micro-lens array (MLA) layer including an array, grid or matrix of micro-lenses, wherein the display layer and the MLA layer are positioned whereupon each micro-lens is positioned in alignment with a corresponding one of the transmission spaces of the display layer and each micro-lens includes a surface that is curved, rounded, or convex facing away from the corresponding transmission space; and a laser light emitting (LLE) layer comprising an array, grid or matrix of laser diodes, wherein each laser diode is positioned in alignment with one micro-lens of the MLA layer and the corresponding transmission space of the display layer, wherein the LLE layer is positioned on a side of the MLA layer opposite the display layer with the curved, rounded, or convex surfaces of the micro-lenses facing the LLE layer.
- Claim: 2. The display of claim 1 , wherein each transmission space is defined by the spacing between at least two, or three, or four of the pixels.
- Claim: 3. The display of claim 1 , wherein an axis of each transmission space is positioned in alignment with an axis of the corresponding one of the transmission spaces of the display layer.
- Claim: 4. The display of claim 1 , wherein the spaced pixels, the spaced subpixels, or both are arranged in rows and columns.
- Claim: 5. The display of claim 1 , wherein each pixel includes at least one of the following: a blue subpixel, a red subpixel, and/or a green subpixel.
- Claim: 6. The display of claim 1 , wherein each laser diode is a vertical-cavity surface-emitting laser.
- Claim: 7. The display of claim 1 , wherein laser light projected by each laser passes through the micro-lens in alignment with the laser whereupon the curved, rounded, or convex surface of said micro-lens causes the laser light to converge and pass through the corresponding transmission space.
- Claim: 8. The display of claim 1 , wherein laser light projected by each laser passes through the micro-lens in alignment with the laser and micro-lenses proximate or adjacent to the micro-lens in alignment with the laser whereupon the diffractive properties of the laser light combined with a pitch of the micro-lens array and the spacing between the laser and micro-lens array causes the laser light to create a reimaging of the convergence of the light that passes through the corresponding transmission space.
- Claim: 9. The display of claim 1 , wherein: the laser light projected by each laser projects in a cone shape; the cone shape laser light projected by each laser passes through the micro-lens in alignment with the laser and one or more micro-lenses proximate or immediately adjacent the micro-lens in alignment with the laser, whereupon the curved, rounded, or convex surface of the micro-lens in alignment with the laser causes the laser light to converge and pass through the corresponding transmission space and each micro-lens proximate or immediately adjacent the micro-lens in alignment with the laser causes the laser light to converge and pass through its corresponding transmission space.
- Claim: 10. The display of claim 1 , wherein: each subpixel is comprised of a light emitting diode (LED); and the display layer includes thin-film-transistors (TFTs) connected to the subpixels by conductive traces for selectively controlling the on-off state of each LED in response to control signals output by a controller to the TFTs.
- Claim: 11. The display of claim 10 , further including: a cover layer, wherein: the subpixels are disposed on a surface of the display layer that faces away from the MLA layer; and the subpixels are positioned between the cover layer and the surface of the display layer that faces away from the MLA layer.
- Claim: 12. The display of claim 11 , wherein the cover layer, the display layer, and the micro-lenses of the MLA layer are each at least partially transmissive of a wavelength of laser light output by each laser diode.
- Claim: 13. The display of claim 12 , wherein the display layer includes a substrate layer positioned between the MLA layer and the array, grid or matrix of spaced pixels and the array, grid or matrix of spaced transmission spaces.
- Claim: 14. A method of using the display of claim 1 with a computer controlled device, comprising: (a) causing a subset of the laser diodes of the LLE layer to project laser light through a subset of the micro-lenses of the MLA layer to an object, whereupon each of said subset of the micro-lenses causes rays of the laser light being projected therethrough to converge and pass through a corresponding transmission space in alignment with the micro-lens; (b) viewing by a camera of a computer controlled device reflections of the laser light from the object; (c) processing by a controller of the computer controlled device the reflections of the laser light on the object viewed by the camera in step (b) to determine a feature of the object; and (d) causing by the controller of the computer controlled device to perform a predetermined function based on the feature of the object determined in step (c).
