A unit pixel of a liquid crystal display panel is made up of a first sub-pixel adapted to allow only any two of red, green and blue lights to pass therethrough, and a second sub-pixel adapted to allow only a remaining one of the red, green and blue lights to pass therethrough, wherein one frame of image is time-divided into n pieces (wherein n is an integer of two or more), and respective image information about the two lights are applied to the first sub-pixel during every duration of the 1/n frame, while applying image information about the remaining one light to the second sub-pixel during a duration of the one frame of image. Further, the respective two lights are emitted during every duration of the 1/n frame in synchronization with applying the respective image information about the two lights, while continuously emitting the remaining one light during the duration of the one frame of image. | 07-01-2010 |

| 20110199405 | DIGITAL GRAY SCALE METHODS AND DEVICES - Methods and devices for generating grayscale using digital pulse width modulation between optical states. Grayscale may be generated for each component color using multiple algorithm cycles per display field. Subsets of binary weighted bit values for data values of each component color may be split across algorithm cycles to reduce the number of data comparisons per color per display field. The total number of data comparisons per color per display field may be reduced by half or more. | 08-18-2011 |
| 20120218323 | MITIGATION OF ARTIFACTS IN PWM ILLUMINATION IMAGING - A system and method for reducing pulse width modulation contouring artifacts. Each input intensity value is translated to at least one non-binary bit pattern for display. Many of the input intensity values are translated to at least two alternate non-binary bit patterns. The alternate codes are used to smooth the transition between intensity codes as major bits are turned on. The smoothing occurs by the gradual transition from codes that do not use the major bit to codes that do use the major bit. Typically the alternate codes are selected based on the location of the pixel in a spatial pattern ( | 08-30-2012 |
