| titleOfInvention | Auto-calibrated digital-to-analog converter for a video display |
| abstract | Each of N current summation type digital-to-analog (D/A) converters of a liquid crystal display driver generates an analog signal which provides pixel video information. In an error sampling interval of the D/A converter, the output signal of the D/A converter developed when the data to be converted is at full scale is compared in a comparator with a reference voltage. An error signal is sampled and is used for varying a control voltage developed in a capacitor. The control voltage controls the current sources of the D/A converter in a current mirror manner. The reference voltage is coupled in common to each of the comparators of the D/A converters. In this way, matching among the D/A converters and the accuracy of each are enhanced. |
