Abstract: A display apparatus includes a display panel, a mirror switching screen, a first photosensitive sensor, a first flexible circuit board and a driver board. The mirror switching screen is disposed on a light-exit side of the display panel. The first photosensitive sensor is configured to sense a light intensity of ambient light at a side of the mirror switching screen away from the display panel. The first flexible circuit board includes a bonding portion, a component portion and a wiring portion. The bonding portion is electrically connected to the mirror switching screen. The first photosensitive sensor is disposed on a side of the component portion proximate to the mirror switching portion.
The wiring portion has lines electrically connected to the first photosensitive sensor and bonding pads of the bonding portion. The driver board is electrically connected to the wiring portion of the first flexible circuit board.

Abstract: An optical device is disclosed. The optical device includes a plurality of reflective pillars extending in a first direction, and the plurality of reflective pillars are arranged in a plurality of rows and a plurality of columns. The first direction is perpendicular to both a row direction and a column direction. Every at least three adjacent reflective pillars define an optical channel extending in the first direction. Each optical channel includes a plurality of reflective surfaces arranged in a circumferential direction of the optical channel, and the plurality of reflective surfaces include two reflective surfaces that are adjacent and perpendicular to each other. A plurality of reflective surfaces defining the optical channel are respectively located on different reflective pillars.
