摘要:
A multi-rod mechanism includes at least one ternary link and a plurality of binary links. The ternary link and the binary links are connected between a first fixing pivot point and a second fixing pivot point to form a combination of the ternary link and the binary links. The combination of the ternary link and the binary links is designed to provide a first movable pivot point and a second movable pivot point between the first fixing pivot point and the second fixing pivot point. In operation, the ternary link and the binary links are rotated to move the first movable pivot point and the second movable pivot point toward or away from each other in opposite directions.

摘要:
An image-forming lens set includes a positive power first lens, an aperture stop, a negative power second lens and a positive power third lens, which are arranged from an object side in order. The first lens has a convex surface facing the object side, and at least one surface thereof is a non-spherical surface. The second lens is a convex-concave lens having a concave surface facing the object side, and at least one surface thereof is a non-spherical surface. The third lens has two non-spherical opposite surfaces including a convex surface facing the object side. At least one of the first, second and third lenses is coated with a layer of optical film for filtering light. By means of the lenses having non-spherical surfaces, the image-forming lens set has a simple structure. By means of the optical film, the image formed in a better quality can achieve.
摘要:
A reflective and a transflective liquid crystal display device and a manufacturing method thereof are provided. The manufacturing method includes the following steps. First, a substrate structure of a reflective or a transflective liquid crystal display device is provided. Next, a reflection layer is formed over the substrate structure, a protection layer is formed over the reflection layer, and a photoresist layer is formed over the protection layer. Then, the photoresist layer is patterned to form a patterned photoresist layer, the protection layer is patterned to form a patterned protection layer, and the reflection layer is patterned to form a patterned reflection layer. Thereafter, the patterned photoresist layer is removed.
