Patent number: 10035461Abstract: 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.Type: GrantFiled: January 4, 2017Date of Patent: July 31, 2018Assignee: UNIDISPLAY INC.Inventors: Sheng-Hsien Lin, Leng-Chieh Lin, Wei-Chieh Wang, Meng-Chia Chan, Ming-Yuan Hsu
