| 20090085937 | Shared Buffer Display Panel Drive Methods and Systems - Methods of driving source lines and/or circuits/systems for driving source lines are provided. Source lines of a display device are driven by comparing first data for driving a first buffer associated with a first source line of the display device and second data for driving a second buffer associated with a second source line of the display device and selectively disabling the second buffer and driving the second source line of the display device with the first buffer based on the comparison of the first and second data. | 04-02-2009 |
| 20100001984 | GAMMA VOLTAGE CONTROLLER, GRADATION VOLTAGE GENERATOR AND DISPLAY DEVICE HAVING THE SAME - A gamma voltage controller includes a gamma distribution unit that generates a plurality of voltages by performing voltage divisions between a first gradation voltage and a N(th) gradation voltage, a gamma selection unit having first through M(th) gamma selectors that respectively select first through M(th) gamma voltages among the plurality of voltages, a gamma buffer unit that changes inflection points of the gamma curve, and buffers the first through M(th) gamma voltages to output buffered first through M(th) gamma voltages, and a gradation distribution unit that generates second through N−1(th) gradation voltages by performing voltage divisions among the buffered first through M(th) gamma voltages. Each of the buffers includes a feedback loop, and some of the buffers change inflection points of the gamma curve. | 01-07-2010 |
| 20110210791 | INTEGRATED CIRCUIT DEVICES HAVING A DATA CONTROLLED AMPLIFIER AND METHODS OF OPERATING THE SAME - An integrated circuit device includes an amplifier circuit that includes first and second differential transistor pairs that are selectively operable responsive to at least one bit of a multi-bit data signal. | 09-01-2011 |

| 20110187755 | Single-Chip Display-Driving Circuit, Display Device and Display System Having the Same - Display devices include a display driving circuit, which is configured to generate a source driving signal and a gate driving signal in response to image data and horizontal and vertical sync signals. This display driving circuit includes a resolution-type generator, a timing controller, a source driving circuit and a gate driving circuit. The resolution-type generator is configured to generate a resolution-type signal in response to a resolution selecting code and the timing controller is configured to generate first image data, a source driver control signal and a gate driver control signal in response to the resolution-type signal, the image data and the horizontal and vertical sync signals. The source driving circuit is configured to generate the source driving signal in response to grayscale voltages, the first image data and the source driver control signal. The gate driving circuit is configured to generate the gate driving signal in response to the gate driver control signal. | 08-04-2011 |
