    Abstract: A display apparatus includes a first display substrate, a second display substrate, pixels, a scan line, a sensing line, a first driver, a second driver, and a coordinate calculator. The pixels include pixel rows and pixel columns. The scan line surrounds at least one pixel row of the pixel rows. The sensing line is insulated from the scan line and surrounds at least one pixel column of the pixel columns. The first driver applies a scan signal to the scan line and the second driver outputs a sensing signal provided from the sensing line. The coordinate calculator receives the sensing signal to calculate coordinate information. Each of the scan line and the sensing line is disposed on different layers from each other.

    Abstract: Embodiments provide a light-emitting device and an electronic apparatus including the same. The light-emitting device includes a first electrode, a second electrode facing the first electrode, m light-emitting units stacked between the first electrode and the second electrode, and m-1 charge generation layers between adjacent ones of the light-emitting. Each light-emitting unit includes an emission layer; the m light-emitting units include a first light-emitting unit, a second light-emitting unit, a third light-emitting unit, a fourth light-emitting unit, and a fifth light-emitting unit; the m−1 charge generation layers include a first charge generation layer, a second charge generation layer, a third charge generation layer, and a fourth charge generation layer; the first light-emitting unit and the second light-emitting unit each emit green light; and the third light-emitting unit, the fourth light-emitting unit, and the fifth light-emitting unit each emit blue light.

    Abstract: A tandem light-emitting device including a first electrode, a second electrode facing the first electrode, m light-emitting units stacked between the first electrode and the second electrode, the m light-emitting units each including an emission layer, and m−1 charge generation layers between two adjacent light-emitting units of the m light-emitting units. M is an integer of 5 or more. The m light-emitting units include first to fifth light-emitting units, in order of proximity to the first electrode. The m−1 charge generation layers include first to fourth charge generation layers, in order of proximity to the first electrode. At least one of the first to fifth light-emitting units emits blue light. At least one of the first to fifth light-emitting units emits green light. The formula 3≤D/(2*λb)≤ 4 is satisfied.
