摘要 |
The present application relates to a display apparatus having a panel including sub-pixels, data lines, and horizontal lines; a sensing circuit to collect sensing data by sensing for external compensation in the horizontal lines; a calculator to determine a characteristic change of each of the sub-pixels using the sensing data to calculate an external compensation value; a data aligner to receive input image data, and when the input image data corresponds to a horizontal line where the sensing is performed, to convert the input image data into compensation image data based on a compensation value; and a data driver to output a compensation data voltage corresponding to the compensation image data to a data line corresponding to the sensed horizontal line before and after the sensing is performed, and output a sensing data voltage to the data line while the sensing is performed. |

1. A display apparatus comprising:
a panel including a plurality of sub-pixels, a plurality of data lines, and a plurality of horizontal lines; a sensing circuit configured to collect sensing data by sensing for external compensation in each of the horizontal lines; a calculator configured to determine a characteristic change of each of the sub-pixels using the sensing data to calculate an external compensation value; a data aligner configured to
receive input image data, andwhen the input image data corresponds to a horizontal line where the sensing is performed, to convert the input image data into compensation image data based on a compensation value; and a data driver configured to output a compensation data voltage corresponding to the compensation image data to a data line corresponding to the sensed horizontal line before and after the sensing is performed, and output a sensing data voltage to the data line while the sensing is performed. |
