Abstract: A double-layer cholesteric liquid crystal display and its manufacturing method are disclosed. The double-layer cholesteric liquid crystal display includes three transparent substrates, two opposing electrode layers, two cholesteric liquid crystal layers, and a first light-absorbing layer. Additionally, the double-layer cholesteric liquid crystal display incorporates two drive ICs and a second light-absorbing layer. The two drive ICs can be positioned either on the same side or on opposite sides within the non-display area of the double-layer cholesteric liquid crystal display. Furthermore, the first cholesteric liquid crystal layer exhibits a first color light, and the second cholesteric liquid crystal layer exhibits a second color light, where the colors are selected as contrasting colors. Additionally, the two cholesteric liquid crystal layers possess mutually opposite optical rotary properties.

Abstract: A silicon interconnect die includes through-substrate via (TSV) structures extending through a silicon substrate; an insulating spacer layer including a horizontally-extending portion overlying a top surface of the silicon substrate and a plurality of tubular insulating material portions laterally surrounding a respective one of the TSV structures; and a front metallic shield layer including a horizontally-extending metallic shield portion and at least one tubular metallic shield portion laterally surrounding a respective one of the tubular insulating material portions.

Abstract: A spliced reflective display includes multiple display devices, a front light guide plate, and at least one light source. Among the multiple display devices, one display device is joined side-by-side with another to form an adjacent joint. The front light guide plate is affixed above the multiple display devices and is close to the display side. It has a top surface near the display side and includes an optical structure. The at least one light source is positioned at the side of the front light guide plate, and light therefrom reflects off the top surface of the front light guide plate onto the multiple display devices, and the reflected light from the display devices forms image light that is directed towards the display side to produce an image. The optical structure directs the path of the image light to obscure the adjacent joint from being visible on the display side.

Abstract: A ZIF socket assembly used with an integrated circuit package (6) comprises a ZIF socket (5) and a protector (7). The socket comprises a base (51) and a sliding cover (53). The base comprises a recess (514) at an end thereof. The sliding cover is moveably assembled on the base for mounting the package and comprises a slot (533) in alignment with the recess. The protector is placed upon the package and comprises a number of legs (71) extending downwardly for pressing against edges of the package. A contacting portion (73) extends outwardly from an edge of the protector. An actuating tool is inserted into the recess through the slot and drives the cover, the package and the protector to move with respect to the base, thereby achieving an electrical connection between the package and the socket.

Abstract: A conductive contact for an electrical connector is disclosed. The conductive contact comprises a lower inserting section for inserting into an external circuit board, an upper contacting section for engaging a mating lead pin of a chip, a middle fixing section for fixing onto a cooperating housing for an electrical connector, and anti-wicking means for prevention of wicking during wave soldering procedure. The anti-wicking means can be an inverted V-shaped groove formed on the fixing section or a horizontal plate stamped from the fixing section. The conductive contact can be formed by stamping and bending.

Abstract: A ZIF PGA socket (20) includes a base (22) having a plurality of passageways (24) extending vertically therethrough for receiving a corresponding number of contacts (26) therein, and a cover (28) having a corresponding number of holes (30) extending therethrough in alignment with the corresponding passageways (24) in the base (22) for allowing a corresponding number of pins extending from the PGA component. A lever (44) includes a cam shaft (48) embedded within a channel (50) formed adjacent the rear region of the socket (20) wherein cover (28) includes a retention device (54) and the base includes a restriction plane (64) to cooperate with the retention device (54) of the cover (28), and both of the retention device (54) and the restriction plane (64) are disposed adjacent the cam shaft (48) for efficiently fastening the cover (28) and the base (22) together to resist the larger resistance force occurring thereabout during the socket (20) in a closed state.
