A display apparatus includes a display panel. A cover window covers the display panel. A first film is arranged over the cover window. The first film has a first rate of change of a storage modulus at frequencies due to external impacts that are below a reference frequency and a second rate of change of the storage modulus at frequencies due to external impacts that are above the reference frequency.

Display apparatus

An electronic device includes a display panel including non-folding areas and a folding area disposed between the non-folding areas, a lower protective film disposed below the display panel, an external light reflective member disposed below the lower protective film, a lower member disposed below the external light reflective member, and cushion members disposed below the lower member. The display panel is foldable along a folding axis. The cushion members are spaced apart from each other and define a cushion hole in the folding area.

Electronic device

An electronic device includes a display panel including a folding area and a non-folding area which is adjacent to the folding area along a first direction, and a support member facing the display panel. The support member includes in order from the display panel, an upper plate which faces the folding area and the non-folding area, has a thickness and in which are defined a plurality of openings corresponding to the folding area, and a lower plate having a thickness which is greater than the thickness of the upper plate and including a first lower plate and a second lower plate each corresponding to the folding area and the non-folding area. At the folding area, the second lower plate is spaced apart from the first lower plate by a gap along the first direction.

A display device includes a first non-folding area, a second non-folding area, and a folding area, which are disposed in a first direction includes a display panel including first to third pixel areas, which are spaced apart from each other on a plane defined in the first direction and a second direction crossing the first direction and a window layer disposed on the display panel. The window layer includes a first rigid part, a second rigid part, and a first soft part, a first interface and a second interface overlaps at least one area of first to third pixel areas on the plane, and an absolute value of a difference in refractive index between the first rigid part and the first soft part is 0.02 or less, and an absolute value of a difference in refractive index between the second rigid part and the first soft part is 0.02 or less.

Display device

A display device according to an embodiment includes a digitizer, a display module disposed on the digitizer, and a support plate disposed between the digitizer and the display module, the support plate including an amorphous nickel alloy, and a range of about 50 wt % to about 95 wt % of nickel is included in the amorphous nickel alloy based on a total weight of the amorphous nickel alloy. The support plate has a non-magnetic property and a flexible property.

A display device includes a display panel which displays an image, an anti-reflection film disposed on a display surface of the display panel, and a plurality of retardation films disposed on the anti-reflection film. Each of the plurality of retardation films has an in-plane retardation of about 1000 nanometers to about 7000 nanometers.

A display device includes a rollable display panel having a first end portion and a second end portion spaced apart from the first end portion, a first roller configured to roll the first end portion, and a second roller configured to roll the second end portion. The second end portion of the rollable display panel may include a transmissive region which external light may pass through. An operation method of the display device includes determining an operation mode, rolling the rollable display panel in a first rotation direction so that the transmissive region is not exposed outside in a first display mode, rolling the rollable display panel in a second rotation direction so that the transmissive region is exposed outside in a second display mode, and displaying an image in a display region exposed outside.

Display device with rollable display panel and operation method thereof

A flexible display device includes: a display panel capable of being bent with respect to a folding line; and a metal plate disposed on the display panel and capable of being bent with respect to the folding line. The metal plate has a plurality of holes disposed on each side of the folding line, the plurality of holes being formed in a zigzag pattern with respect to the folding line.

Flexible display device

An method of attaching a polarizing plate to a liquid crystal display panel includes inspecting an alignment axis of the liquid crystal display panel using an optical axis inspector; controlling a position of the liquid crystal display panel with respect to a reference alignment axis, according to a result of the inspecting the alignment axis of the liquid crystal display panel; providing the polarizing plate to the liquid crystal display panel at the controlled position thereof; and attaching the polarizing plate to the liquid crystal panel at the controlled position thereof.
