摘要： A fingerprint sensing module includes a first substrate, an active device, a photosensitive element layer, a collimation structure layer, a second substrate, a plurality of micro lenses, and a spacer pattern. The active device is disposed on the first substrate. The photosensitive element layer is disposed on the first substrate and is electrically connected to the active device. The collimation structure layer is disposed on the photosensitive element layer. The second substrate is disposed on the collimation structure layer. The micro lenses are disposed on a surface of the collimation structure layer facing away from the photosensitive element layer, and overlap the photosensitive element layer. The micro lenses are divided into a plurality of microlens groups, and the microlens groups are respectively located in a plurality of sensing pixel areas of the fingerprint sensing module. The spacer pattern extends between the microlens groups.

摘要： A fingerprint sensing module, including a photosensitive element layer and a color filter layer, is provided. The photosensitive element layer has multiple photosensitive regions, and includes a substrate and multiple photosensitive pixels. The photosensitive pixels have multiple photosensitive patterns overlapping the photosensitive regions. The photosensitive pixels include multiple first photosensitive pixels overlapping multiple first photosensitive regions and multiple second photosensitive pixels overlapping multiple second photosensitive regions. A percentage value of a number of the second photosensitive pixels to a number of the photosensitive pixels is less than 30%. An orthographic projection area of each of the first photosensitive regions is different from an orthographic projection area of each of the second photosensitive regions. The color filter layer has multiple openings overlapping the first photosensitive pixels and multiple first color filter patterns overlapping the second photosensitive pixels.

摘要： A touch apparatus includes a substrate, a plurality of pixel structures, a first touch electrode, a second touch electrode, a third touch electrode and a first conductive pattern. The first touch electrode and the second touch electrode are located at a first side of a transparent window. The third touch electrode is located at a second side of the transparent window. The first touch electrode, the second touch electrode and the third touch electrode are sequentially arranged in a first direction. A main portion of the first conductive pattern is electrically connected to the first touch electrode. The main portion of the first conductive pattern overlaps with the second touch electrode and is electrically isolated from the second touch electrode. A dummy portion of the first conductive pattern is electrically connected to the third touch electrode and structurally separated from the main portion of the first conductive pattern.
