  • Light source unit, manufacturing method thereof, and display device having the same
    Patent number: 8152354
    Abstract: A light source unit includes; a first base layer, a plurality of conductive pads disposed on the first base layer, a second base layer disposed on the first base layer and including a plurality of openings therein exposing the plurality of conductive pads, a wiring portion disposed on the second base layer, and a plurality of light source elements disposed on the plurality of conductive pads exposed by the plurality of openings in the second base layer.
    Type: Grant
    Filed: October 31, 2008
    Date of Patent: April 10, 2012
    Assignee: Samsung Electronics Co., Ltd.
    Inventors: Ki-Hyun Hong, Hee-Won Ko, Sang-Kil Lee
  • Driving apparatus for display device and display device including the same and method of driving the same
    Patent number: 7764265
    Abstract: The present invention relates to a driving apparatus for a display device and a display device including the same, as well as a method of driving a display device. The driving apparatus for a display device including a plurality of pixels each with a switching element has a driving voltage generator for generating a first driving voltage at a temperature higher than a reference temperature relative to a predetermined ambient temperature and a second driving voltage higher than the first driving voltage at a temperature lower than the reference temperature, and a gate signal generator for generating a plurality of gate voltages based on the driving voltage. In this manner, power consumption can be reduced by increasing a driving voltage only at a temperature that requires low temperature driving.
