  • Patent number: 12044930
    Abstract: An electronic paper device includes a touch cover plate module, a front lighting module and an electronic paper display module. The touch cover plate module has a top plate, a touch sensor and a bottom plate. The top plate is disposed with a black bezel. The bottom plate is disposed with a transparent conductive film with a low refractive index. The front lighting module has a light guide plate. An outer edge portion of the light guide plate is disposed with a point light source. The point light source emits light from a side of the light guide plate to convert the emitted light into a surface light source. An upper surface of the light guide plate is attached on the transparent conductive film to form a total reflection interface on the light guide plate and an electromagnetic mask layer between the touch sensor and the electronic paper display module.

  • Publication number: 20230373441
    Abstract: A heating sticker includes a protective layer, a thermogenic layer, an electrode layer, a cover layer and an adhesive layer, which are superposed in order. The thermogenic layer is a conductive film with transparent carbon nanobuds and defined with a heating area and a non-heating area. The heating area is disposed with insulative grooves. The non-heating area is distributed with micro blocks which are arranged insulatively. The electrode layer has a conductive wire and a ground wire. The conductive wire surrounds the heating area in a non-closed shape. The ground wire is located between the front end and the rear end of the conductive wire and connected to a periphery of the heating area. Conductivity of each of the conductive wire and the ground wire is higher than conductivity of the thermogenic layer. An outer surface of the cover layer is a modified surface which is treated with plasma.

  • Patent number: 11215923
    Abstract: The method includes the steps of: a) dividing a large-scale touch sensing pattern to be manufactured into multiple divisional patterns and producing multiple photomasks corresponding to the multiple divisional patterns; b) providing a substrate with a conductive layer; c) disposing a photoresist layer on the conductive layer; d) a first exposure process: forming an exposing divisional pattern and multiple first targets the photoresist layer; e) an adjacent exposure process: forming an adjacent exposing divisional pattern and multiple second targets, and adjacently connecting the adjacent exposing divisional pattern and the exposing divisional pattern originally on the photoresist layer; f) repeating the adjacent exposure process to form multiple adjacent exposing divisional patterns until a complete exposing pattern has been assembled; g) performing a developing process to the photoresist layer; and h) etching the conductive layer to form the large-scale touch sensing pattern on the conductive layer.
