Abstract: An organic light-emitting display device comprises a display panel having a transmission area through which external light passes, and a non-transmission area having transmittance lower than that of the transmission area; a data driver supplying a data signal to the display panel; a gate driver supplying a gate signal to the display panel; a timing controller controlling the data driver and the gate driver; and a sensor package module disposed on a rear surface of the display panel and disposed to correspond to the transmission area, wherein the number of conductive films stacked in the transmission area is smaller than that of conductive films stacked in the non-transmission area.

Abstract: Disclosed is an organic light emitting display device including an encapsulation layer covering a pixel array layer provided on a substrate and a cover window coupled to a touch sensing layer. The touch sensing layer may include a first touch electrode layer provided on the encapsulation layer, a second touch electrode layer provided on the first touch electrode layer, and a pressure reaction member provided between the first touch electrode layer and the second touch electrode layer. Electrical characteristic of the pressure reaction member may be changed according to force applied to the pressure reaction member.

Abstract: An electronic device has a force touch function. The electronic device includes an image display module having a touch electrode. A cover window attaches to a front surface of the image display module. A housing receives the image display module therein, and supports the cover window. A panel moving part is between the housing and the image display module. A driving circuit senses a touch force based on a distance between the image display module and the housing which are spaced from each other with the panel moving part interposed in-between.
