    Abstract: A display apparatus for detecting three-dimensional (3D) spatial information. The display apparatus includes a display panel having a plurality of active subpixels in a display area configured with multiple gaps respectively between at least some active subpixels, the display panel including a counter substrate at front and a backplane substrate at back; an optical layer at a back side of the backplane substrate; multiple light sensors attached discretely on a back side of the optical layer and substantially aligned with the multiple gaps in the display area; and a light source on the backplane substrate and configured to provide an infrared light signal in a direction toward a field of view beyond the counter substrate. The multiple light sensors are configured to detect respective infrared light signals reflected from multiple different regions of an object in the field of view for collectively deducing 3D spatial information of the object.

    Abstract: A drive method for a texture recognition device and a texture recognition device. The texture recognition device includes a light source array and an image sensor array. The image sensor array includes a plurality of image sensors, the plurality of image sensors are configured to receive light emitted from the plurality of sub-light sources and then reflected by a texture to the plurality of image sensors for a texture collection; the drive method includes: at a first moment, the light source array operating to provide a first photosensitive light source, and at the first moment or a second moment different from the first moment, the light source array operating to provide a second photosensitive light source. A first imaging range of the first photosensitive light source on the image sensor array partially overlaps a second imaging range of the second photosensitive light source on the image sensor array.
