Abstract:
A monolithic light guiding and dispersing plate is provided in a backlighted display panel for receiving input light from one or more edge sources and for guiding the received light throughout the plate for substantially uniform reflection upwardly and substantially uniform dispersal toward an image forming plane located above the light guiding and dispersing plate. In one embodiment, the light guiding and dispersing plate has a light receiving surface upon which the light generated by an edge light source is incident, a top major surface which is adjacent to the light receiving surface and on which a plurality of first protrusions are formed and elongated in a first direction, wherein the first protrusions have cross-sections in the shapes of partial ellipses. The plate further has a bottom major surface in which light reflecting recesses are defined to reflect light upwardly towards the top major surface.

An apparatus and method for controlling noise caused by vibration in a camera module for a mobile device are provided. The method includes transmitting a vibration signal sensed by a vibration sensor to a Choice Coil Motor (VCM) driver based on the vibration signal, applying, by the VCM driver, a reverse bias to a VCM upon receiving, by the VCM driver, the vibration signal from the vibration sensor, and exerting, by the VCM to which the reverse bias is applied, an electromagnetic force in a reverse direction in order to fix and halt an actuator.
Abstract:
Disclosed herein is a photoresist composition suitable for coating onto a large substrate and having improved coating uniformity to prevent occurrence of stains, a coating method thereof, a method of forming an organic film pattern using the same, and a display device fabricated thereby. The present invention thus provides a photoresist composition comprising a polymeric resin with an incorporated polysiloxane resin, a photosensitive compound, and an organic solvent. Accordingly, the photoresist composition can be coated onto a large substrate by a spinless coating method, and thereby coating uniformity can be improved, the occurrence of stains such as cumulous stains and resin streaks can be prevented, and the coating rate and quality of a final product prepared using the photoresist composition can also thereby be enhanced.

A complementary metal-oxide-semiconductor image sensor may include: a semiconductor substrate; a photodiode formed on a first portion of the semiconductor substrate; a transfer gate formed on the semiconductor substrate, near the photodiode, to transfer optical charges accumulated in the photodiode; a floating diffusion area formed on a second portion of the semiconductor substrate, on an opposite side of the transfer gate from the photodiode, to accommodate the optical charges; and/or a channel area formed under the transfer gate and contacting a side of the photodiode to transfer the optical charges. The transfer gate may be formed, at least in part, of transparent material. A method of manufacturing a complimentary metal-oxide-semiconductor image sensor may include: forming the photodiode; forming the floating diffusion area, separate from the photodiode; and/or forming the transfer gate, near the photodiode, to transfer optical charges accumulated in the photodiode.
Abstract:
An apparatus for driving a plasma display panel includes a first driver and a second driver and a first power supplier and a second power supplier for generating sustain discharge pulses having no negative (−) level. The first driver includes a first capacitor charged to a first voltage and is coupled to a power source for supplying a voltage Vs and a ground voltage. The first driver, coupled to one terminal of a panel capacitor, operates to alternately apply double the voltage Vs formed by the power source and the first capacitor and the ground voltage to the one terminal of the panel capacitor. The second power supplier, coupled to the power source and the ground voltage, includes a second capacitor charged to Vs. The second driver coupled to the other terminal of the panel capacitor operates to alternately apply double the voltage Vs formed by the power source and the second capacitor and the ground voltage to the other terminal of the panel capacitor. Here, one of the first driver and the second driver applies the ground voltage to the panel capacitor, while the other applies double the voltage Vs to the panel capacitor.
