Abstract
A display device for measuring biometric information such as blood pressure by utilizing both display pixels and light sensing pixels within a display panel. The display device includes a main driving circuit that dynamically sets and adjusts light emission conditions, including emission color and luminance based on the user's touch area and shape, thereby optimizing the detection of biosignals such as pulse waves. The system enhances the signal-to-noise ratio (SNR) and improves the accuracy of biometric measurements.
