    Abstract: The present invention discloses a touch panel structure, a method for forming the same and a touch device having the same. A touch panel structure of the present invention comprises a substrate, a color layer, an inorganic layer, and a photoresist layer. The color layer is disposed on a surface of the substrate. The inorganic layer is disposed on a surface of the color layer which is opposite to the substrate. The photoresist layer is disposed on a surface of the inorganic layer which is opposite to the substrate, wherein the color layer and the photoresist layer have different surface tensions. For electronic products that rely on the Colorful OGS (One Glass Solution) technology, by providing an inorganic layer between the color layer and the photoresist layer, problems related to different surface tensions when the layers are stacked during the manufacturing process of a touch panel can be solved.

  • Patent number: 8237683
    Abstract: For solving the defect that a hardware clock of a serial peripheral interface bus has to cooperate with slower software-simulated clocks used by a microprocessor while applying serial peripheral interface buses on a large-scale touch panel, a programmable logic device is used as a bridge of communicating information between the micro processor and sensors. Therefore, the microprocessor no longer has to take execution time to simulate serial peripheral interface buses by software, and is able to program hardware clocks of each of the serial peripheral interface buses according to speed requirements of different sensors, so that sensing signals of a plurality of sensors may be integrated on a touch device having the large-scale touch panel, and a processing speed of the touch device in processing the sensing signals may be optimized as a result.
