Abstract: A pressure sensor is provided that uses an electric field effect. The pressure sensor includes a first electrode extending in a vertical direction and defining a core region, a second electrode disposed to entirely surround the first electrode, a first insulating layer interposed between the first and second electrodes, a ground electrode electrically insulated from the second electrode, the ground electrode being disposed to surround the second electrode and a membrane connected to the ground electrode and positioned to cover the first and second electrodes, and the membrane being provided to generate an electric field in an adjacent region together with the first and second electrodes. The particular arrangements described herein are configured to make the electric field distort when an object approaches thereto, enhancing sensitivity by measuring change in capacitance, pressure, and impedance.

Abstract: A backlight unit capable of preventing a degradation in luminance, while achieving a reduction in heat generation and a reduction in manufacturing costs by adjusting the arrangement of the light sources while reducing the number of the light sources is disclosed. The disclosed backlight unit includes a bottom cover formed with a plurality of light source groups each including a plurality of light sources arranged in one direction. The spacing of the adjacent light source groups increases gradually from a central portion of the bottom cover to opposite edges of the bottom cover.

Abstract: A backlight unit for an LCD device produces a more uniform brightness by reducing or preventing bright lines occurring at the location of each LED device. The backlight unit includes a plurality of light guide plates which are arranged to overlap with an incident portion of adjacent light guide plate to at least partially cover the LED array. Accordingly, the backlight unit can prevent the generation of bright lines and hot spots caused when the light guide plate does not cover the LED array. As a result, the LCD device may improve images of uniform brightness.

Abstract: A backlight assembly has a lamp driving device for driving external electrode fluorescent lamps (EEFLs) parallel connected each other. The lamp driving device includes a power switch transistor, a diode, an inverter and a PWM controller. The transistor converts external DC power signal into pulse power signal based on switching signal, the diode prevents rush current from flowing into the transistor. The inverter converts the pulse power signal into AC power signal, raises voltage level of the AC power signal, and provides the lamps with the raised AC power signal. The PWM controller is activated by external on/off signal to provide the transistor with the switching signal so as to regulate voltage level of the AC power signal. The EEFLs can maintain a constant current level, and the backlight assembly can have characteristics of uniform luminance, high luminance and high heat efficiency.
