The metal layer is disposed on one of the first side and the second side of the rollable panel and outside the rollable panel. In a rolled mode, at least a part of the metal layer is positioned between the first portion and the second portion of the rollable panel.

Abstract: A display device includes a display panel including a rollable portion and a non-rollable portion. The display panel includes a supporting structure including a groove disposed on a first side of the supporting structure, a substrate disposed on a second side of the supporting structure and the first side opposite to the second side, and a circuit board fixed onto a back of the display panel. The non-rollable portion has a first region. A first region of the circuit board is joined to the first region of the non-rollable portion. The non-rollable portion has a first end and a second end. The first end is connected to the rollable portion. The second end is connected to the circuit board.

Abstract: The disclosure provides a transparent display device including a display panel. The display panel includes a display area, a non-display area, and a plurality of pixels. The non-display area is adjacent to the display area. The plurality of pixels are disposed in the display area. A difference between a transmittance of the display area and a transmittance of the non-display area is less than 30% of the transmittance of the display area.

Abstract: Disclosed is a bio sensing device including a medium layer, a light emitting element and an optical sensor. The light emitting element is configured to emit a light toward a user's skin layer, in which the light passes through the medium layer and has a maximum intensity in a first wavelength. The optical sensor is configured to receive a reflected part of the light from the user's skin layer, in which the reflected part of the light passes through the medium layer, and the medium layer has a first transmittance greater than 60% with respect to the first wavelength.

Abstract: An electronic device and an electronic device operation method are disposed. The electronic device includes a flexible element and a controller.
