A luminance difference correction method and a light emitting display apparatus using the same is discussed. The luminance difference correction method can include receiving by an camera an image, which is output from a camera region of a light emitting display panel and is reflected by at least one of a reflector or a cover glass associated with the apparatus. The method can further include analyzing by a controller the image received by the camera, and varying a level of at least one of (i) a gamma voltage used to generate a data voltage to be output to data lines included in the light emitting display panel, and (ii) one or more of driving voltages supplied to pixels included in the light emitting display panel.

Discussed is a display device including a first substrate; a display panel including first and second electrodes disposed on the first substrate, and a light-emitting layer located between the first electrode and the second electrode; an encapsulation layer disposed on the second electrode of the display panel; a first touch electrode unit disposed on the encapsulation layer and extending in one of a first direction and a second direction intersecting with the first direction; and a first passivation layer disposed on the first touch electrode unit.

Touch display device and method for manufacturing touch display device

A display device includes a flexible display panel, an ultrasonic fingerprint sensor which is disposed below a rear surface of an active area of the flexible display panel and has a first thickness and a first width, a cushion structure which is disposed below the rear surface of the flexible display panel, surrounds the periphery of the ultrasonic fingerprint sensor, and has a second thickness larger than the first thickness, and a circuit board which is electrically connected to the ultrasonic fingerprint sensor and has a second width larger than the first width.
