Abstract: Provided is a display panel, including: a base substrate, a display structure, a black matrix pattern, and a cylindrical lens structure layer. The black matrix pattern includes a plurality of first openings. The display panel is provided with a plurality of sub-pixel regions arranged in rows and columns. The first openings are disposed in the sub-pixel regions. The cylindrical lens structure layer includes a plurality of strip-shaped cylindrical lens structure and has a plurality of focal lines in an orthographic projection on the black matrix pattern. The focal lines are parallel to the length direction of the cylindrical lens structures. The focal lines partition each sub-pixel region into a plurality of regions. One of the plurality of regions is a non-crosstalk region. The black matrix pattern further includes second openings in the non-crosstalk regions. The second openings are disposed outside regions where the first openings are disposed.

Abstract: The present disclosure relates to a display device, a door body and a cabinet body. The display device includes: an information collecting assembly configured to collect environment information; a communication module configured to perform wireless-communication linking to an Internet-of-Things device, to transmit the environment information to the Internet-of-Things device, and receive multimedia information sent by the Internet-of-Things device; and a display module configured to display the multimedia information, wherein the multimedia information includes audio-video advertisement information.

Abstract: The present disclosure provides a voice interaction system, a voice interaction method, and a smart device. The system includes: a voice interaction unit, a photoelectric sensing unit, and an instruction control unit configured to determine whether the voice interaction unit is in an on state, determine, when the voice interaction unit is in the on state, whether the voice interaction unit receives a target voice instruction within a predetermined time; control, when the target voice instruction is received within the predetermined time, a smart device to perform an action corresponding to the target voice instruction according to the target voice instruction of the user received and identified by the voice interaction unit; and send, when the voice instruction is not received within the predetermined time, a standby instruction to the voice interaction unit.

Abstract: A time-of-flight camera module and a display device are provided. The time-of-flight module includes: a first carrier board, a second carrier board, a structure support, an infrared laser emission unit, a lens and a time-of-flight sensor. The first carrier board, the structure support and the second carrier board are stacked, and the first carrier board and the second carrier board are fixed on both sides of the structure support, respectively. The infrared laser emission unit is arranged on a side of the first carrier board away from the structure support, and the first carrier board includes a lens via hole located on a side of the infrared laser emission unit, the structure support includes a support via hole corresponding to the lens via hole, and the lens passes through the support via hole. The time-of-flight sensor is arranged on the second carrier board and is configured to sense infrared light collected by the lens to generate depth information.
