  • 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: 11467400
    Abstract: An information display method and an information display system are provided. The method is adapted to the information display system including a first image capturing device and a transparent display, and the method includes the following steps. A pattern image is obtained by shooting a pattern placed on a real object through the first image capturing device, wherein the real object is located on one side of the transparent display. Relative position information between the transparent display and the pattern is obtained according to the pattern image. Augmented image data is obtained according to the relative position information. The augmented image data is displayed through the transparent display, wherein the augmented image data include a virtual object augmented based on the real object.

  • Publication number: 20220165808
    Abstract: An electronic device includes a transparent substrate, a number of pixel structures and a first trace structure. The transparent substrate includes a transparent region and a trace region. Each of the pixel structures has a sub-pixel structure of first color and a sub-pixel structure of second color. The sub-pixel structure of first color has a light emitting element of first color. The sub-pixel structure of second color has a light emitting element of second color. The first trace structure includes a first main trace, a first auxiliary trace and a second auxiliary trace. The first main trace is disposed in the trace region and surrounds a portion of the transparent region. The first auxiliary trace and the second auxiliary trace are electrically connected to the first main trace, and are electrically connected to the corresponding sub-pixel structure of first color and the corresponding sub-pixel structure of second color, respectively.

  • Publication number: 20060147968
    Abstract: The present invention provides a biochip substrate used for immobilizing biomaterials, which has a matrix and at least one metal oxide thread-like nano-object formed vertically on a surface of the matrix. The metal oxide thread-like nano-object is employed for immobilizing the biomaterial onto the matrix of the chip substrate directly, without complicated immobilizing processes by using cross-linking agents or curing agents, and thereby simplifying the process of fabrication. Arrangement as such makes it suitable for purification of a biomaterial. On the other hand, the metal oxide thread-like nano-object characterized by having an enormous surface area is suitable for fabricating immunosensor chip and capable of maintaining high activity and reactivity of biomaterials, so as to increase speed and yield of reactions.
