Abstract: A display apparatus includes a display panel, a driving controller and a data driver. The display panel includes a low deterioration region and a high deterioration region. The driving controller generates a data signal based on input image data. The data driver converts the data signal to a data voltage and outputs the data voltage to the display panel. The driving controller includes a deterioration compensator which generates the data signal based on a deterioration ratio. The deterioration ratios may be a ratio between a sensing current of the low deterioration region and a sensing current of the high deterioration region.

Abstract: A method of providing a biomarker on a display device includes displaying an initial guidance image that guides a user to place a finger on a sensing region of the display device. A first photoplethysmography (PPG) signal is generated by performing a PPG sensing operation when the finger is located in the sensing region. At least one tilt guidance image is displayed that requests to tilt the finger in at least one direction. At least one second PPG signal is generated by performing the PPG sensing operation when the finger is tilted in the at least one direction. An optimal PPG signal having a highest signal quality is selected among the first PPG signal and the at least one second PPG signal. The display device then displays a biomarker of the user determined based on the optimal PPG signal.
