| 20110157494 | DISPLAY APPARATUS AND METHOD FOR DRIVING THE SAME - A display apparatus and a method of driving the same are provided. The display apparatus includes a backlight module, a liquid crystal panel and a controller. The backlight module has a plurality of light emitting regions capable of emitting light individually. The liquid crystal panel is disposed at a side of the backlight module. The controller is electrically coupled to the backlight module and the liquid crystal panel. When the liquid crystal panel updates a left-eye image to a right-eye image row by row along a column-direction, the controller sequentially turns on and off the light emitting regions along the column-direction, such that a whole region of the liquid crystal panel lighted by light emitting region displays the left-eye image or the right-eye image. | 06-30-2011 |

| 20090212720 | LIGHT EMITTING DIODE DRIVING SYSTEM - An exemplary light emitting diode driving system includes a protective circuit, a rectifying circuit, a driving circuit, a light emitting diode module and a detecting circuit. The protective circuit, the rectifying circuit, the driving circuit and the light emitting diode module are connected in series. The driving circuit is configured for driving the light emitting diode to emit light. The detecting circuit has predetermined voltages or current values stored therein. The detecting circuit detects the respective voltage or current of the protective circuit, the rectifying circuit and the driving circuit, and compares the respective voltage or current with the predetermined voltages or currents. | 08-27-2009 |
| 20100308736 | STREET LAMP SYSTEM - An exemplary street lamp system includes a monitoring center, a first street lamp, a first sensor, a first signal receiving unit, a first signal sending unit, and a first power management unit. The monitoring center is configured for sending a monitoring signal. The first sensor is configured for detecting an operating state of the first street lamp and generating a first detection signal. The first signal receiving unit is configured for receiving the monitoring signal. The first signal sending unit selectively operates in a power-on state where the first signal sending unit sends a feedback signal to the monitoring center based on the monitoring signal, or a power-off state where the first signal sending unit does not send the feedback signal to the monitoring center. The first power management unit is configured for switching the first signal sending unit to the power-off state in response to the first detection signal. | 12-09-2010 |
