  • Patent number: 10451659
    Abstract: A detection circuit of an electronic device includes a resistance detecting circuit and a voltage supplying circuit, wherein the detecting circuit is coupled to an input circuit which is coupled to the electronic device and comprises a plurality of resistors respectively coupled to a plurality of switches, wherein the resistance detecting circuit is arranged to detect whether the input circuit has a resistance variation and generate a detecting signal indicative of the resistance variation; and the voltage supplying circuit is coupled to the resistance detecting circuit to supply a first voltage signal, wherein the voltage supplying circuit receives the detecting signal, and selectively switches the first voltage signal to a second voltage signal according to the detecting signal; wherein the resistance detecting circuit determines whether at least one of the plurality of switches is closed according to the second voltage signal.

  • Patent number: 10035461
    Abstract: An electronic device includes a first substrate, a first electrode, a second substrate, a second electrode, an electrochromic material layer, a sealant, and a light shielding pattern layer. The first electrode is disposed on the first substrate. The second electrode is disposed on the second substrate. The electrochromic material layer is disposed between the first electrode and the second electrode. The sealant is disposed between the first substrate and the second substrate and surrounds the electrochromic material layer. The light shielding pattern layer is disposed on the first substrate. The light shielding pattern layer shields the sealant and a little portion of the electrochromic material layer near the sealant. The first electrode disposed on the first substrate and the second electrode disposed on the second substrate are not electrically connected to each other.
