Abstract: According to an embodiment of the present disclosure, an electrical device may include a substrate, an electrical element, a first barrier structure and a gas barrier layer. The substrate includes an active region and a periphery region surrounding the active region. The electrical element is disposed in the active region. The first barrier structure is disposed in the periphery region and surrounds the electrical element, wherein the first barrier structure includes a first conductive layer. The gas barrier layer covers the electrical element and the first barrier structure.

Abstract: A display including a plurality of display units and a plurality of holes is provided. Each of the display units includes a transparent area. Each of the holes is formed by a part of the transparent areas. At least one of the holes satisfies 2 ? ? ? ? A ? S < 8 3 ? 3 ? ? A , wherein A is an area of each of the holes and the S is a perimeter of each of the holes, and the at least one of the holes is a hole of a non-quadrilateral-type shape. These holes are arranged along a first direction in staggered arrangement, parts of projections of the holes along a second direction are overlapped with one another, and the first direction is different from the second direction.

Abstract: The disclosure provides an electrowetting display device. The electrowetting display device includes a first substrate and a second substrate disposed to each other. A first electrode layer may dispose on the first substrate. A second electrode layer may dispose on the second substrate. A hydrophobic dielectric layer is disposed on the first electrode layer. A first pixel rib is disposed on the first substrate. A second pixel rib is disposed on the first pixel rib. A water contact angle of the second pixel rib may be larger than that of the first pixel rib. A first liquid and a second liquid may be disposed in between the first substrate and the second substrate.

Abstract: An aliphatic polyester polymer compositions and preparation method thereof. The invention provides a bioresorbable aliphatic polyester copolymer, comprising the reaction product of a first polyester, a second polyester, and a coupling agent. Specifically, the first polyester and second polyester have the same repeat units, but different weight average molecular weights. Methods for preparing the aliphatic polyester copolymer are provided, in which the first polyester reacts with the second polyester in the presence of the coupling agent, undergoing copolymerization.
