Abstract: A waterproof structure for a portable terminal including a flexible printed circuit (FPC) extending outside of a first housing of a pair of housings from inside the first housing and arranged inside of a second housing of the pair of housings. A wiring hole is formed in each housing to provide a path allowing passage of the FPC therethrough. A waterproof member provided in the wiring hole substantially contacts at least inner walls of the housings and an outer circumferential surface of the FPC to prevent movement of the FPC. An outer circumferential surface of the waterproof member substantially contacts a circumference of an inlet of the wiring hole or an inner wall of the wiring hole. The waterproof member is provided between the housing of the portable terminal and the FPC improving a waterproof function and preventing moisture or water from being introduced into the housing of the terminal.

Abstract: Provided are a method of manufacturing a flexible piezoelectric energy harvesting device using a piezoelectric composite, and a flexible piezoelectric energy harvesting device manufactured by the same. The method of manufacturing the flexible piezoelectric energy harvesting device includes: forming a first electrode layer on a first flexible substrate; spin-coating a piezoelectric composite layer on the first electrode layer, wherein the piezoelectric composite layer is produced by mixing piezoelectric powder with polymer; performing heat treatment on the piezoelectric composite layer to harden the piezoelectric composite layer; and bonding a second flexible substrate with a second electrode layer on the hardened piezoelectric composite layer. Therefore, it is possible to simplify a manufacturing process and manufacture a high-performance flexible piezoelectric energy harvesting device having various sizes and patterns.

Abstract: Provided is a method of fabricating an oxide thin film device using laser lift-off and an oxide thin film device fabricated by the same. The method includes: forming an oxide thin film on a growth substrate; bonding a temporary substrate on the oxide thin film; irradiating laser onto the growth substrate to separate the oxide thin film on which the temporary substrate has been bonded from the growth substrate; bonding a device substrate on the oxide thin film on which the temporary substrate has been bonded; and forming an upper electrode film on the oxide thin film. Therefore, it is possible to overcome problems caused by a defective layer by transferring an oxide thin film transferred on a polymer-based temporary substrate onto a device substrate, without using an interface on which a defective layer formed due to oxygen diffusion upon laser lift-off is formed.

Abstract: Provided are a thin film condenser for high-density packaging, a method for manufacturing the same and a high-density package substrate. The thin film condenser for high-density packaging, includes: a support substrate; a lower electrode formed on the support substrate; a dielectric thin film formed on the lower electrode; and an upper electrode formed on the dielectric thin film. Provided also is a method for manufacturing the same. The high-density package substrate, includes: at least two stacked substrates; thin film condensers embedded in the stacked substrates; an internal connection electrode formed in the stacked substrates and connecting the thin film condensers in series or in parallel; a surface electrode formed on the surface of the outermost substrate among the stacked substrates and connected to the internal connection electrode; and an integrated circuit connected to the surface electrode via a bump.

Abstract: A portable terminal including a body, a front deco positioned along a periphery of the body, a main battery cover positioned on a rear surface of the body to cover a battery, and a waterproofing cover interchangeable with the front deco and the main battery cover so that when substituted for the main battery cover and front deco all water intrusion paths on the portable terminal are sealed.

Abstract: A hinge apparatus for a folder-type portable communication device, wherein a body portion and a folder portion can be coupled or separated by applying a force to a hinge cap or moving a hinge dummy laterally. The device includes a body portion and a folder portion coupled to the body portion to pivot around a hinge axis, and a center hinge arm provided in the body portion. First and second side hinge arms are provided in the folder portion, and a hinge cap is provided in the first side hinge is pushed with an external force. A hinge shaft is coupled with or separated from the first side hinge arm by retracting or protruding via pushing the hinge cap, and a hinge dummy provided in the center hinge arm is coupled with or separated from the second side hinge arm by moving laterally along the hinge axis.

Abstract: A display device for an electronic appliance includes: a touch screen panel; an LCD panel; and an intermediate member provided between the touch screen panel and the LCD panel. The intermediate member has an air passage for allowing air to flow into and out of an interior space defined by the intermediate member between the touch screen panel and the LCD panel. The air passage has a plurality of paths oriented in different directions.

Abstract: Disclosed is a portable electronic device having an interceptor for cutting off foreign substances such as water, dust or the like from being entered between the coupling surfaces thereof.
