Abstract: A display device includes a display panel, a light source on a substrate, and an adjacent light source. The adjacent light source is spaced apart from the light source by a predetermined distance. The light source emits light to irradiate an interface between the substrate and a member of the display panel via a lens. Light emitted from the light source irradiates a spot on the interface via the lens with luminance below a darkness level. The spot is aligned with the adjacent light source in a direction perpendicular to the substrate.

Abstract: A display device includes a display panel, a first light source, and second light source. The first and second light sources are respectively aligned with a first spot and second spot in a direction perpendicular to a substrate. The first light source irradiates the first spot and a third spot with luminance of a first value, respectively. The first light source irradiates a midpoint between the first and second spots with a luminance value that is half of the first value.

Abstract: A display device (100) includes a display panel (110), a first light source (E), and second light source (F). The first and second light sources (E, F) are respectively aligned with a first spot (5) and second spot (6) in a direction perpendicular to a substrate (310).

The first light source (E) irradiates a midpoint (N?) between the first and second spots with a luminance value that is half of the addition of the first value and second value.

Abstract: The present invention discloses a pattern projector based on VCSEL array. The VCSEL array has a plurality of VCSELs configured in a regular pattern on a VCSEL chip. A certain number but not all of the VCSELs are selected for two groups. In one operational mode, VCSELs of one group are powered on to form a low-density irregular pattern. A lens system projects an image of the low-density irregular pattern on a diffractive optical element (DOE). The DOE multiplies a replica of the image and generates a matrix of the replicas on a target surface. In another operational mode, VCSELs of the two groups are powered on simultaneously or the second group is powered on alone to form a high-density irregular pattern. An image of the high-density irregular pattern is projected on the DOE. Thus, the pattern projector may provide irregular light patterns for low-resolution and high-resolution 3D sensing.

Abstract: Nuclear magnetic resonance (NMR) simulations of a porous medium are provided based on physical data such as CT images. A method of evaluating the surface relaxation of the porous medium based on random-walk NMR simulations includes a novel algorithm to derive the absorption probabilities of the random walkers, and algorithms that can evaluate more accurately the surface area and reduce the voxel discretization effect. The methods can be applied to conventional porous media as well as unconventional porous media such as reservoir rocks with high surface-to-volume ratios, for example tight sandstones or shale.
