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 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.
