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.

Abstract: A blood pressure measurement method using a display device including: a display panel including first sub-pixels and second sub-pixels; a pressure sensor to sense a pressure applied from the outside; and a photo-sensor to sense light, includes: generating a first pulse wave signal according to light emitted by the first sub-pixels and sensed by the photo-sensor; generating a second pulse wave signal according to light emitted by the second sub-pixels and sensed by the photo-sensor; generating a third pulse wave signal by removing noise from the second pulse wave signal based on the first pulse wave signal, the second pulse wave signal, and a maximum value of the first pulse wave signal; and calculating blood pressure information based on the third pulse wave signal and a pressure measurement value sensed by the pressure sensor. The blood pressure information is displayed on the display panel.

Abstract: Provided is a display device including a plurality of normal display pixel, one boost display pixel having a higher maximum luminance than the plurality of normal display pixels, and one light-receiving pixel disposed adjacent to the boost display pixel. Each of the normal display pixel, the boost display pixel, and the light-receiving pixel includes a first electrode, a second electrode, and an active layer, which is interposed between the first and second electrodes. The first electrodes of the normal display pixel, the boost display pixel, and the light-receiving pixel are disposed in the same layer. The second electrodes of the normal display pixel, the boost display pixel, and the light-receiving pixel are integrally connected to one another.
