Abstract: A display device includes a display panel, a first measurement enabling unit, a second measurement enabling unit, and a processor. The display panel may display an image. The display panel includes a first non-folding part, a second non-folding part, and a first folding part. The first non-folding part is connected through the folding part to the second non-folding part. The first measurement enabling unit is disposed in or overlaps with the first non-folding part and may emit first light. The second measurement enabling unit is disposed in or overlaps with the second non-folding part and may output a first signal in response to at least one of a received force and received light. The processor is connected to the second measurement enabling unit and may use the first signal to determine a blood pressure value.
