Abstract: A display module includes a display area and a non-display area disposed outside the display area on a plane. The display module includes a base layer, a circuit device layer, a display device layer, a thin film encapsulation layer, and a touch sensing layer. An inorganic layer of the touch sensing layer contacts an inorganic layer of the circuit device layer exposed by an organic layer of the circuit device layer. An inorganic layer of the thin film encapsulation layer is disposed between the inorganic layer of the touch sensing layer and the inorganic layer of the circuit device layer to block a moisture penetration path which causes delamination of the thin film encapsulation layer.

Abstract: Provided is an organic light emitting display module including an active area, a pad area, and a boundary area between the active area and the pad area. Unlike the active area and the pad area, since the boundary area does not include an inorganic layer, less stress is applied to the boundary area when the boundary area is bent. Display panel pads and touch sensing member pads are disposed at the same height without having a height difference therebetween. Thus, a dummy pad may be added to remove the height difference between the display panel pads and the touch sensing member pads.

Abstract: An electronic device includes: a display layer; a sensor layer to operate in a first mode for detecting a first input by a touch, and a second mode different from the first mode and including a plurality of frames; and a sensor controller to control the sensor layer. Each of the plurality of frames includes a downlink signal including information used to detect a second input by an input device, and a sensing signal including information used to detect the first input. When the first input is detected in the second mode, the sensor controller is to: output first coordinates of the first input based on the sensing signal of at least one frame in which the first input is detected; and correct second coordinates of the second input based on the first coordinates during a period of at least two frames including the at least one frame.
