  • Publication number: 20240086005
    Abstract: A touch display device includes a driving substrate, a display medium layer, a conductive film, a touch panel, a circuit board and a reinforcing structure layer. The driving substrate includes a first portion, a second portion and a bending portion connecting the first portion and the second portion. The display medium layer is disposed on the first portion of the driving structure. The conductive film is disposed on the first portion of the driving structure and located on the display medium layer. The touch panel is disposed on the first portion of the driving substrate and located on the conductive film. The circuit board is disposed on the second portion of the driving substrate. The reinforcing structure layer is disposed on the bending portion of the driving substrate and extends to the first portion to seal the space.

  • Patent number: 11916155
    Abstract: An optoelectronic package and a method for producing the optoelectronic package are provided. The optoelectronic package includes a carrier, a photonic device, a first encapsulant and a second encapsulant. The photonic device is disposed on the carrier. The first encapsulant covers the carrier and is disposed around the photonic device. The second encapsulant covers the first encapsulant and the photonic device. The first encapsulant has a topmost position and a bottommost position, and the topmost position is not higher than a surface of the photonic device.

  • Publication number: 20240045300
    Abstract: A touch display device includes a driving substrate, a display medium layer, an electrode substrate, a touch panel, a flexible circuit board, a water-blocking adhesive layer, and a sealant layer. The touch panel is disposed on the electrode substrate and has a bonding area. The flexible circuit board is bonded to the bonding area of the touch panel and extends to outside of the touch panel. The water-blocking adhesive layer is directly connected between a bottom surface of the flexible circuit board outside the touch panel and a top surface of the driving substrate. The sealant layer is disposed on the driving substrate and seals an edge of the display medium layer, an edge of the electrode substrate, and an edge of the touch panel. In a cross-sectional view, the sealant layer is located between the water-blocking adhesive layer and the edge of the display medium layer.

  • Publication number: 20230320012
    Abstract: A display device includes a display area and a periphery area. The display device includes a display panel and a touch module located on the display panel. The display panel includes a driving substrate, a display medium layer located on the driving substrate, a top electrode located on the display medium layer, and a sealant surrounding the display medium layer and the top electrode. The sealant includes a first section and at least one second section connected with the first section. The first section is located between the top electrode and the driving substrate. A thickness of the second section is greater than a thickness of the first section. The touch module includes a bonding region located in the periphery region. An orthogonal projection of the bonding region on the driving substrate overlaps an orthogonal projection of the first section on the driving substrate.
