摘要:
The present invention provides a Light Emitting Diode (LED) array module for providing backlight, which can be used as an independent device with a plurality of LEDs being integrally packaged, and which can be universally used regardless of a screen size, and a backlight unit having the same. The LED array module used as a light source of backlight includes a bar-shaped Printed Circuit Board (PCB) on which conductive patterns for transmitting power are formed, a base formed on the PCB and made of a heat conductive material, a plurality of LED chips mounted on the base in a line and electrically connected to the conductive patterns of the PCB, a reflector formed to surround the plurality of the LED chips and adapted to reflect light radiated from the plurality of LED chips upward, and a lens formed above the plurality of LED chips and reflector to have a bar shape and adapted to diffuse the light radiated from the plurality of LED chips and reflector in a horizontal direction.

Disclosed herein is an MEMS variable capacitor and its driving method, the MEMS variable capacitor including, a first electrode, a second electrode floating over the first electrode upper part, a fixed electrode separated at the second electrode side surface, and a drifting electrode placed between the second electrode and the fixed electrode, connected to the second electrode, and physically contacting the fixed electrode by a voltage applied to the fixed electrode.
摘要:
Disclosed is an impedance matching device. Variable devices of the impedance matching device installed in a mobile terminal, such as a portable terminal, are configured to have a MEMS structure. The MEMS structure and other components are integrated as one package, so the manufacturing cost is reduced and the manufacturing efficiency is improved.

摘要:
Disclosed is a drawer structure for storing condensed water generated during the drying procedure. The drawer prevents the condensed water form being leaked out of the dryer though the condensed water is fully filled in the drawer and overflowed from the drawer. Thus, a user may not throw away the condensed water whenever the laundry is dried.
