Definitions

• the present disclosure relates to a display device comprising a display cover plate, and in particular a glass display cover plate wherein edge portions of the glass display cover plate are protected by a bracket that minimizes fracture at the edges of the display cover plate.
• the term display device is intended to encompass all electronic devices capable of displaying visual content, including but not limited to computers, including but not limited to laptop, notebook, tablet and desktop computing devices; mobile telephones, cameras (both movie and still) and; televisions (TV).
• Each of the foregoing devices includes many component parts including the physical case or cabinet in which individual components may reside, circuit boards, power supplies, circuit elements such as integrated electronic components, and of course the display panel itself.
• these display panels are flat display panels comprising liquid crystal display elements, organic light emitting diode (OLED) display elements, or plasma display elements, and of course the glass or plastic substrates on which many of these elements are disposed and/or enclosed by.
• a protective display cover plate may be positioned between an observer and the display panel.
• the display cover plate not only protects the display panel from mechanical damage, but may in some instances be used to conceal edge bezels used to house the edge portions of the display panel and components associated therewith.
• the display cover plate itself may be susceptible to damage, principally because operations performed to shape the display cover plate, such as cutting and/or grinding, may leave flaws at the edges of the display cover plate that may serve as sources for cracks if subject to tensile stress.
• the bezel may also protect the edges of the glass components of the display panel, including the protective display cover plate positioned in front of the display panel relative to an observer of the displayed image produced by the display panel.
• display cover plates were often formed of plastic sheet in the early days of hand-held electronic devices, a growing trend has been toward chemically strengthened glass.
• Such chemically strengthened glass has superior scratch resistance when compared to plastic materials. This scratch resistance offers a particularly advantage for cell phones that are often carried in pockets, along with keys, loose coins and other small hard objects that can contact the display cover plate.
• the edges of the glass cover plates can be susceptible to failure arising from fractures originating at these edge flaws.
• glass fracture occurs when existing flaws experience tensile stress. Such tensile stress can come from flexing of the glass. Accordingly, as the glass cover plate becomes thinner, it can be more susceptible to flexure.
• reducing the size of, or completely eliminating the edge bezel formerly serving to protect and/or support the glass cover plate edges only heightens the danger of failure.
• the inventors herein have found that such thin bezel, or bezel-less device designs may benefit when a supporting structure as disclosed herein is positioned behind the glass cover plate, and in particular behind at least the edge portions of the display cover plate relative to an image observer. That is, when a suitable supporting structure is positioned at the back side of the display cover plate. Further benefit can be derived if the supporting structure includes one or more members that provide a cushion or bumper at the perimeter edge surfaces of the display cover plate. While designs using an edge bumper are not precisely bezel-less in the sense that a structure other than the glass cover plate extends beyond the perimeter of the glass cover plate, such bumper structures can be made suitably thin that the edge bumper is visually unobtrusive.
• a display device comprising: a cabinet; a display panel; a display cover plate having a first planar major surface, a second planar major surface, and an edge surface connected to the first and second major surfaces; and an edge bracket comprising a first portion positioned adjacent to the first major surface of the display cover plate.
• the edge bracket may further comprise a second portion forming a closed loop around a perimeter of the display cover plate. A surface of the second portion may be perpendicular to a surface of the first portion.
• the display cover plate comprises a chemically strengthened glass, such as an ion-exchanged glass.
• the display device may comprise an adhesive positioned between the edge bracket and the display cover plate.
• the adhesive can be, for example, a resilient material such as a silicone material.
• the display cover plate can be affixed to the display panel with an epoxy having an index of refraction substantially matching an index of refraction of the display panel.
• the edge bracket comprises a first portion substantially parallel with the first major surface.
• the edge bracket comprises a second portion perpendicular to the first major surface.
• the edge bracket comprises a second portion connected to the first portion, and the second portion comprises a curved surface.

• a resilient material is disposed between the display cover plate and the bracket.
• a foam material may be positioned between the display cover plate and the bracket.
• a display device comprising: a cabinet; a display panel; a glass display cover plate having a first major surface, a second major surface, and an edge surface substantially perpendicular to the first and second major surfaces; and an edge bracket comprising a first portion positioned adjacent to the first major surface of the display cover plate and a second portion forming a closed loop around a perimeter of the display cover plate, the second portion comprising a curved surface.
• the second portion may include a hollow interior channel that extends parallel with the edge surface of the display cover plate.
• the display cover plate can be attached to the display panel with an adhesive.
• a resilient material is disposed between the display cover plate and the edge bracket.
• the resilient material can be an adhesive material such as a silicone material, a foam material, or an adhesive material can be used on conjunction with an adhesive material.
• the edge bracket itself may comprises a resilient material.
• a display device comprising: a cabinet; a display panel mounted in the cabinet; a display cover plate having a first major surface, a second major surface, and an edge surface substantially perpendicular to the first and second major surfaces, the display cover plate being attached to the display panel with an adhesive; and an edge bracket comprising a first portion positioned adjacent to the first major surface of the display cover plate and a second portion forming a closed loop around a perimeter of the display cover plate.
• the display panel can comprise, for example, an organic material or a liquid crystal material.
• the edge bracket can include a hollow channel extending parallel with the edge surface. In some embodiments a resilient material is positioned between the edge bracket and the display plate.

• the aesthetics of display devices are affected by the size and appearance of a bezel that typically exists around a perimeter of such display devices, and in particular around a perimeter of the display panel portion that forms the viewed image.
• the bezel of a display device is often used to house electronics for driving the pixels of the display panel, as well as, in certain instances, to provide backlighting for the display device if the display panel is edge lighted.
• an LCD television display panel may include a plurality of backlighting light emitting diodes (LEDs) maintained within the bezel region of the display device.
• a display cover plate is positioned between the display panel and the observer, wherein the display cover plate is fixed to the display device in some fashion.
• the display cover plate may serve multiple purposes.
• the display cover plate may be purely aesthetic in that it provides an essentially edge-to-edge surface that is sleeker and uninterrupted by discontinuities that might be caused by a bezel.
• the display cover plate may be edge lighted so that the cover plate guides light along the edges. In the dark, the display cover plate edges may then glow according to the color of the light. Glowing edges may be activated, for example, when the television is turned off.
• the display cover plate may be configured to stretch the displayed image through the use of prisms or other optic elements so that the display panel bezel is concealed behind the image.
• the display cover plate may be configured to respond to touch in order to activate certain functions of the electronic device. For example, while such touch functionality was previously restricted to computing devices, the line between computing devices and telecommunication devices has blurred, so that many telecommunication devices (e.g. cell phones) include powerful processors, and are structured to run any one or more of thousands of available software applications with the touch of a finger.
• the display cover plate may also serve a protective function by providing a degree of impact resistance to the display panel positioned behind it.
• a liquid crystal or organic light emitting diode (OLED) display panel may be less than 1.5 mm in thickness, and is therefore easily susceptible to impact damage. Consequently, a display cover plate may be positioned in front of the display panel, between the display panel and the observer/user of the device.
• the display cover plate protects the display panel from both impact damage and more cosmetic damage, such as scratching.
• the display cover plate may be plastic.
• a tempered (strengthened) glass such as a chemically (e.g. ion-exchanged) or thermally strengthened glass, as such glass not only serves to protect the device (e.g. display panel) from impact damage, but is quite scratch resistant in and of itself, therefore extending the perceived useful life of the device.
• Glass that may be used to form a display cover plate is typically processed to provide a glass having the requisite dimensions for the device.
• the display cover plate having certain predetermined dimensions may have been cut from a much larger original glass sheet.
• the display cover plate is typically equal to or less than about 1 mm.
• suitable display cover plate thicknesses include equal to or less than about 0.7 mm, equal to or less than about 0.5 mm, or equal to or less than about 0.3 mm.
• a thickness of the display cover plate may be equal to or less than about 100 ⁇ .
• the cutting process may leave flaws at the edges of the display cover plate. Grinding or shaping of the edges of the glass display cover plate may eliminate some of these flaws.

• a curved edge face, wherein the edge face gradually transitions to the major surfaces of the display cover plate avoids the formation of sharp corners than can be easily damaged.
• Display cover plate 18 is positioned between display panel 14 and the viewer or observer O of the image formed by display panel 14. In some instances display cover plate 18 may be adhered to display panel 14 via an adhesive layer 31 such as a refractive index-matched epoxy.
• display cover plate 18 may have a refractive index that matches or nearly matches the refractive index of the observer-side portion of display panel 14 (i.e. the surface of display panel 14 facing display cover plate 18) such that the display cover plate appears to be homogeneous with the display panel.
• Display cover plate 18 may be, for example, a chemically strengthened glass sheet, such as an ion- exchanged glass.

• a hollow second portion 46 may be more resilient than a solid second portion 46, in effect forming a buckle zone where impact with second portion 46 may cause second portion 46 to collapse into the hollow channel and absorb the impact energy.
