Abstract: A display device is provided that includes a plurality of pixels, a plurality of optical sensors, an emission line connected to the pixels, and an emission driver connected to the emission line. The emission driver outputs a first emission signal to the emission line having a first frame frequency in a first mode for displaying an image using the pixels and outputs a second emission signal to the emission line having a second frame frequency in a second mode for sensing light using the optical sensors. The second frame frequency is different from the first frame frequency.

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.
