| 20090096736 | DRIVING APPARATUS AND DISPLAY DEVICE INCLUDING THE SAME - The present invention relates to a driving circuit for a liquid crystal display and a driving method thereof. A signal controller of the driving circuit generates a data signal according to an input image signal input to the display device, generates a clock signal according to the input control signal, and generates a differential pair image signal by modulating the clock signal to the data signal. Here, a data signal period of the differential pair image signal and a clock signal period are converted with a different level and are output. A data driver of the driving device receives the differential pair image signal, divides the data signal and the clock signal from the differential pair image signal, and generates a data voltage by sampling a data signal by using the clock signal. | 04-16-2009 |

| 20100110097 | DRIVING DEVICE OF A LIGHT SOURCE MODULE, LIGHT SOURCE MODULE HAVING THE DRIVING DEVICE, DRIVING METHOD OF THE LIGHT SOURCE MODULE, AND DISPLAY DEVICE HAVING THE DRIVING DEVICE - A light source module includes a plurality of light-emitting blocks. A local-dimming driver drives the light-emitting blocks based on a received clock signal (first reference clock) and received dimming levels. The clock signal is input to a liquid crystal display panel and is also input to the local-dimming driver but is delayed within the local-dimming driver by fixed propagation delay. A delay modeling part performs modeling of the fixed propagation delay amount. The clock signal input to the local-dimming driver is first phase-compensated (delayed) by a phase compensation amount to synchronize the driving signals output by the local-dimming driver with the clock signal. The sum of the modeled propagation delay amount and the phase compensation amount is equal to an integral multiple of the period of the clock signal. The driving signal of the light-emitting blocks are synchronized and in phase with the clock signal. | 05-06-2010 |
