A display device including a display area and a non-display area disposed outside the display area, the display device including a first display substrate, a second display substrate opposite to the first display substrate, and a sealing member disposed between the first display substrate and the second display substrate in the non-display area and coupling the first display substrate to the second display substrate, in which the first display substrate includes a first substrate and an organic layer disposed on the first substrate, the organic layer includes a plurality of dam patterns disposed in the non-display area, and the dam patterns include a first dam pattern not overlapping the sealing member and having a first trench formed on a surface of the first dam pattern, and a second dam pattern overlapping the sealing member.

The invention is notably directed to a transflective display device. The device comprises a set of pixels, wherein each of the pixels comprises a portion of bi-stable, phase change material, hereafter a PCM portion, having at least two reversibly switchable states, in which it has two different values of refractive index and/or optical absorption. The device further comprises one or more spacers, optically transmissive, and extending under PCM portions of the set of pixels. One or more reflectors extend under the one or more spacers. An energization structure is in thermal or electrical communication with the PCM portions, via the one or more spacers. Moreover, a display controller is configured to selectively energize, via the energization structure, PCM portions of the pixels, so as to reversibly switch a state of a PCM portion of any of the pixels from one of its reversibly switchable states to the other. A backlight unit is furthermore configured, in the device, to allow illumination of the PCM portions through the one or more spacers. The backlight unit is controlled by a backlight unit controller, which is configured for modulating one or more physical properties of light emitted from the backlight unit. The invention is further directed to related devices and methods of operation.

A display panel, a touch display device, and a method for manufacturing a touch display device are provided in the present disclosure. The display panel includes a display area and a non-display area adjacent to the display area. The display panel includes a first substrate and a second substrate disposed opposite to each other; a first narrow border sealant located in the non-display area, and a liquid crystal layer located in the display area disposed between the first substrate and the second substrate; and a first reflective layer disposed on at least one side of the first narrow border sealant.

A method for fabricating a liquid crystal phase modulation device is provided. The method includes detecting thicknesses of a plurality of portions of a reference liquid crystal layer of a reference liquid crystal phase modulation sample; determining a distribution according to the thicknesses of the portions of the reference liquid crystal layer; forming a plurality of spacers over a first substrate in the determined distribution; and combining the first substrate with a second substrate and a liquid crystal layer to form the liquid crystal phase modulation device.

Smart windows, on which the level of visible light transmission can be electrically switched, are produced by laminating a special switchable film between the two layers of a glass laminate The film is made by sandwiching an emulsion containing the switchable variable light transmission active material between a set of electrodes. One of the challenges of producing said laminates is preventing the migration of plasticizers and moisture from the plastic bonding layer of the laminate into the emulsion where it can degrade performance. By applying a sealing member to each electrode layer along the periphery the emulsion is protected and in a manner that facilitates automation of the process.

A display panel comprising a display region, a non-display region around the display region, and a transition display region located between the display region and the non-display region, wherein the display panel comprises: a display base plate; an encapsulation cover plate located on the display base plate and configured to seal the display base plate; a support column disposed between the display base plate and the encapsulation cover plate, and configured to support the encapsulation cover plate. In the transition display region, a surface of the encapsulation cover plate close to the display base plate is provided with a first groove, and/or a surface of the display base plate close to the encapsulation cover plate is provided with a second groove.

To provide a technique for suppressing brightness non-uniformity of an area illuminated by a light source and also suppressing a decline in contrast between areas caused by incidence of a luminous flux of the area to another area. Provided is a light guide plate including: a diverging portion which is provided on an opposite side of a light exit surface from which light is emitted, the diverging portion causing a luminous flux emitted from a light emitting element to diverge; and a restricting portion which is provided, when a prescribed range from the light emitting element on the light exit surface is defined as an illuminated area illuminated by the light emitting element, in at least a periphery of the illuminated area on the light exit surface and which deflects or shields light traveling from inside toward outside of the illuminated area to restrict traveling, toward a side of the light exit surface, of light traveling toward the outside of the illuminated area.
