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: A display device is provided. The display device includes a display panel including a pixel configured to display an image and a photo-sensor configured to sense incident light, a pressure sensor disposed on one surface of the display panel and configured to sense a pressure applied via a portion of a user’s body, and a processor. The processor is configured to generate a pulse wave signal according to an amount of incident light sensed by the photo-sensor and an optical signal corresponding to the amount of incident light in response to determining that a pressure measurement value corresponding to the pressure is within a pressure request range corresponding to a pressure interval, and calculate blood pressure information based on the pulse wave signal.

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.
