An electrophoretic display including a low-modulus adhesive foam. The electrophoretic display additionally includes a conductive integrated barrier layer including a light-transmissive electrode and a moisture barrier. In some embodiments, the resulting electrophoretic display may include touch sensing, a front light, color, and a digitizing layer to record interactions with a stylus. In some embodiments, the display includes a color filter array.

An optical path control member according to an embodiment comprises: a first substrate; a first electrode disposed on the upper part of the first substrate; a second substrate disposed on the first substrate; a second electrode disposed on the lower part of the second substrate; and a light conversion unit disposed between the first electrode and the second electrode. The light conversion unit includes a partition wall portion and a receiving portion that are alternately disposed. The receiving portion changes light transmittance according to the application of voltage. The partition wall portion includes a base partition wall portion and a separating partition wall portion. A plurality of pores are disposed in at least one of the base partition wall portion or the separating partition wall portion. The density per unit area of partition material in the separating partition wall portion is less than the density per unit area of partition material in the base partition wall portion.

An electronic apparatus includes a flexible display device and a roller. The flexible display device includes a driving substrate, a display layer on the driving substrate, and a front protective layer covering the display layer. The flexible display device has an end portion fixed to the roller. The roller includes a holding groove, a receiving slot, and a retraction assembly. The holding groove is recessed from an external surface of the roller. The end portion is in the holding groove. The flexible display device further includes a main body portion outside the holding groove. A thickness of the end portion is less than a thickness of the main body portion. The receiving slot is recessed from the external surface. The retraction assembly is disposed in the receiving slot. When the retraction assembly abuts against the flexible display device, the retraction assembly is pressed into the receiving slot.

A display device includes a flexible display panel, a sealant, and a first reinforcing structure. The flexible display panel includes a lower substrate, an upper substrate, and a display medium layer disposed between the lower substrate and the upper substrate. Each of the lower substrate and the upper substrate has an edge region. A centerline of the flexible display panel is parallel to a short side of the flexible display panel. The sealant is disposed between the edge region of the lower substrate and the edge region of the upper substrate. The first reinforcing structure is disposed among the sealant, the edge region of the lower substrate, and the edge region of the upper substrate. The centerline of the flexible display panel passes through the first reinforcing structure, and the elastic modulus of the first reinforcing structure is greater than that of the sealant.

A vehicular display that ensures no cooped-up feeling is felt by an occupant providing limited visibility arranged on a transparent outer panel of a vehicle is an electronic paper that displays a video on a vehicle exterior. The electronic paper is provided with a plurality of hole portions to have a light transmission region through which a light is transmitted in the electronic paper. In a state where the electronic paper is viewed in a thickness direction, a hole occupancy as a ratio of an area of the plurality of hole portions to a whole area of the light transmission region falls within a range of 40% or more and 80% or less, and a maximum length that connects two points on a peripheral edge of each of the hole portions falls within a range of 0.5 mm or more and 8.0 mm or less.

Some embodiments are directed to a light modulator comprising transparent or reflective substrates, multiple electrodes being applied to the substrates in a pattern across the substrate. A controller may apply an electric potential to the electrodes to obtain an electro-magnetic field between the electrodes providing electrophoretic movement of the particles towards or from an electrode.
