  • Patent number: 11973260
    Abstract: A light-transmitting antenna includes a substrate, a first and a second conductive pattern. The first and the second conductive pattern is disposed on a first and a second surface of the substrate respectively. The first conductive pattern includes a first feeder unit, a first and a second radiation unit, a first and a second coupling unit and a first parasitic unit. The first feeder unit is connected to the second radiation unit. The first and the second radiation unit are located between the first and the second coupling unit. One side and the other side of the first parasitic unit is connected to the second coupling unit and adjacent to the first coupling unit respectively. The second conductive pattern includes a second feeder unit, a third coupling unit, a second parasitic unit, and a fourth coupling unit.

  • Publication number: 20240120656
    Abstract: A light-transmitting antenna includes a substrate, a first conductive pattern, and a second conductive pattern. The first conductive pattern has a first feeder unit, a first radiation unit, a second radiation unit, and a first connection unit. The first feeder unit and the first connection unit are connected to two sides of the first radiation unit. The first connection unit connects the first radiation unit and the second radiation unit. The second conductive pattern has a second feeder unit, a third radiation unit, a fourth radiation unit, and a second connection unit. The second feeder unit and the second connection unit are connected to two sides of the third radiation unit. The second connection unit connects the third radiation unit and the fourth radiation unit. An orthogonal projection of the second feeder unit on a first surface of the substrate at least partially overlaps the first feeder unit.

  • Patent number: 9978298
    Abstract: A display panel including a plurality of digital code display units is provided. The digital code display units respectively display digital codes. Each of the digital code display units includes a plurality of display segments. The display segments are at least grouped into a first group and a second group. A signal waveform of at least one of a plurality of common voltage signals that drive the first group is the same as a signal waveform of at least one of a plurality of common voltage signals that drive the second group. Furthermore, a driving method of the display panel is also provided.
