Abstract: A support assembly includes a left support frame, a right support frame, and a bracket. The left support frame and the right support frame are both slidably connected to the bracket. The bracket defines receiving grooves. The left support frame includes a first tooth portion. The right support frame includes a second tooth portion. When the support assembly is in a folded state, teeth of the first tooth portion and teeth of the second tooth portion are received in the receiving grooves to support the screen assembly in a retracted state; when the support assembly is in an unfolded state, the teeth of the first tooth portion and the teeth of the second tooth portion extend out of the receiving grooves to support the screen assembly in an extension state. A dial plate and a smart bracelet are further provided.

Abstract: Provided is a display device. The display device includes: a flexible display panel, a roller fixed to a lower edge of the display panel, a plurality of links having one end connected to an upper edge of the display panel, a driving unit which is disposed proximate the roller and configured to rotate the roller, and an elastic member which is connected to the other end of each of the plurality of links and disposed outside of the roller. Accordingly, the force of the driving unit is directly transmitted to the roller and the force of the elastic member is directly transmitted to the links, such that the configuration and operation of manipulating the display device between a rolled configuration and an unrolled configuration is simplified.

Abstract: The display device includes a housing, a first roller portion, a second roller portion, a rail portion, and a flexible display panel. The housing includes a support plate. The first roller portion is disposed at a first side of the support plate and is connected to the housing by a first sliding portion. The second roller portion is disposed at a second side of the support plate and is connected to the housing by a second sliding portion. The rail portion includes fixing rails affixed to the support plate, first moving rails connected to the first roller portion and engaged with the fixing rails, and second moving rails connected to the second roller portion and engaged with the fixing rails. The flexible display panel covers the rail portion. The flexible display panel has ends respectively connected to the first roller portion and the second roller portion.

Abstract: A display device according to an exemplary embodiment of the present invention includes: a display panel configured to display an image; a first supporting plate positioned to support the display panel thereon, the first supporting plate being rotatable based on a first rotation axis extending in a first direction; a second supporting plate positioned to support the display panel thereon, the second supporting plate being rotatable based on a second rotation axis extending in the first direction so that the first and second supporting plates then face each other with the display panel folded therebetween; and a first tension application unit disposed at the first supporting plate and configured to apply tension to the display panel in a second direction crossing the first direction.

Abstract: Embodiments of the present invention provide methods and apparatuses that can control rigidity of a flexible display. Embodiments of the present invention enable a user of the flexible display to control rigidity of the flexible display based on user preference, sensing information, program instruction, or combinations thereof. Embodiments of the present invention provide several ways to control rigidity of the flexible display by manipulating one or more rigidity control members disposed on the flexible display. Accordingly, embodiments of the present invention provide a way to allow the flexible display to have varying rigidity throughout portions of the flexible display.

Abstract: A window panel for a display apparatus is provided comprising a first reinforced layer formed at a first predetermined depth from entire upper and lower surfaces, a second reinforced layer formed at a second predetermined depth from a side surface connecting an edge of the upper surface and an edge of the lower surface, and a non-reinforced portion formed at least a portion of the side surface.

Abstract: A display device (1) has an extendible screen (2) and at least one extendible side member (3). The extendible screen (2) is extendible in an extension direction from a relatively compact form to an extended form. The screen (2) in the extended form has opposed edges (17) that are substantially parallel to the extension direction. An extendible side member (3) is provided for at least one of said opposed edges (17). The or each extendible side member (3) is extendible to provide support to and structural rigidity to the screen (2) when the screen (2) is in the extended form. The display device (1) provides an extendible rigid screen (2) suitable for example for creating a rigid collapsible tablet computer, or enabling a compact portable display to support a rigid touch-screen, or for incorporation into a mobile phone or remote control unit.

Abstract: A safety barrier comprising a support, a partition frame hingedly connected to the support, and a retractable membrane attached to one end of the partition frame. The partition frame and the support can be extended across an opening, such as a doorway, to securely position the barrier within the opening. The partition frame includes a first member hingedly connected to the support and a second member slidingly engaged to the first member. The retractable member may be deployed toward an opposite end of the partition frame to close off the opening.

Abstract: A collapsible security grille is provided comprising two conventional face-to-face sets of rigid grille bars (2, 9) pivotally interconnected at their intersections, wherein all the pivotal connectors (4) are uniformly and non-adjustably spaced apart along their respective grille bars in one said sets, but are free, as far as the second set is concerned, to undergo small sliding displacements along the grille bars of that set. In this way the stresses that ordinarily lead to jamming, jerky action and noise are automatically compensated at the point and instant of their origin. It is preferred that the pivotal connectors around the periphery of the second set are likewise non-adjustably spaced apart, so that every such connector at a grille bar meeting point (6) (as distinct from a crossing point 8) is spaced from both of the two next adjacent crossing-point connectors (8).

Abstract: The application relates to a convertible automobile with a windscreen which is arranged behind a row of seats and which extends vertically upwards and beyond the top of the seats and which extends for the entire interior width of the vehicle. In order to develop a windscreen of this type in such a way that annoying draft phenomena are prevented while the typical "convertible feel" is maintained, the windscreen is formed by a stretched elastically deformable net which causes a deceleration of the air flow impinging from the rear of the vehicle towards the front.

Abstract: A cold frame for providing an environment conducive to the growing of plants having walls and a flexible, light-transmitting cover member which is flexed to form a ventilation opening. The cover member is flexed manually or by means responsive to the temperature of the interior of the cold frame.
