Abstract: A display apparatus which is also able to receive and identify fingerprints comprises a first substrate, a second substrate, a liquid crystal layer, a plurality of dummy pixel units located in a non-display region, a fingerprint identification module, and a plurality of data extending lines. Each of the dummy units comprises first and second auxiliary electrodes. The fingerprint identification module comprises signal transmitting layer and signal receiving components on the signal transmitting layer. The signal receiving component receives reflected ultrasonic wave and converts the received waves into fingerprint signal. The data extending line is electrically connected with the dummy pixel unit. The signal receiving component transmits the fingerprint signals to the at least one first auxiliary electrode and the data extending line thus receives the fingerprint signal.

Abstract: A touch device includes a display panel with a plurality of pixel regions in a matrix, and a touch panel disposed on the display panel. The touch panel detects touch operations. The touch panel includes a substrate, a first conduction layer disposed on a surface of the substrate, and a second conduction layer disposed on a surface of the substrate. The first conduction layer includes a plurality of first conduction units arranged along a first direction. The second conduction layer includes a plurality of second conduction units arranged along a second direction perpendicular to the first direction. The first conduction units and the second conduction units are respectively formed by a plurality of randomized metal meshes connected with each other. The randomized metal mesh is formed based on a virtual randomized mesh shifted by a virtual regular mesh shift.

Abstract: An autostereoscopic display apparatus is provided. The autostereoscopic display apparatus includes a liquid-crystal panel and a barrier cell. The barrier cell includes a first substrate, a second substrate, and a liquid-crystal layer. The first substrate includes a first electrode. The second substrate includes a second electrode and a third electrode, wherein the second and third electrodes are separated from each other. The liquid-crystal layer is disposed between the first and second substrates. A black region between the first and third electrodes is formed when a first voltage is applied to the first and second electrodes and a second voltage is applied to the third electrode.
