CROSS-REFERENCE TO OTHER APPLICATIONS 
     The present application is a continuation of U.S. application Ser. No. 13/246,707, filed Sep. 27, 2011, entitled “HOUSING FOR PORTABLE ELECTRONIC DEVICE WITH REDUCED BORDER REGION,” which claims the benefit of U.S. Provisional Application No. 61/482,513 filed May 4, 2011 of the same title, the contents of which are incorporated herein by reference in their entirety for all purposes. 
    
    
     BACKGROUND 
     Conventionally, a portable electronic device has a housing that encases the various electrical components of the portable electronic device. Often, the portable electronic device has a display arrangement that includes various layers. The various layers usually include at least a display technology layer, and may additionally include a sensing arrangement (e.g., touch sensors or touch screen) and/or a cover window disposed over the display technology layer. The cover window can be a plastic or glass cover that provides a protective outer surface that protects the display technology layer. The cover window can form part of an outer surface for the housing of the portable electronic device. Conventionally, supporting or securing the cover window to other portions of the housing tends to impede usage of a peripheral area of the cover window. 
     Nevertheless, as portable electronic device continue to be made smaller, thinner and/or more powerful, there remains a continuing need to provide improved techniques and structures for supporting cover windows of portable electronic device housings. 
     SUMMARY 
     The invention pertains to an electronic device having a housing structure that is configured to receive at least one glass cover. The glass cover serves to cover a display assembly provided within the electronic device. The glass cover can be secured to the housing structure so as to facilitate providing a narrow border between an active display area and an outer edge of the housing structure. The enclosure for the electronic device can be thin yet be sufficiently strong to be suitable for use in electronic devices, such as portable electronic devices.

     DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION 
     Embodiments are described herein in the context of a housing for an electronic device. The housing can make use of an outer member, which can be formed of glass. The outer member can be aligned, protected and/or secured with respect to other portions of the housing for the electronic device. The electronic device can be portable and in some cases handheld. 
     According to one aspect, the invention pertains to an electronic device having a housing structure that is configured to receive at least one glass cover. The glass cover serves to cover a display assembly provided within the electronic device. The glass cover can be secured to the housing structure so as to facilitate providing a narrow border between an active display area and an outer edge of the housing structure. The enclosure for the electronic device can be thin yet be sufficiently strong to be suitable for use in electronic devices, such as portable electronic devices. 
     The following detailed description is illustrative only, and is not intended to be in any way limiting. Other embodiments will readily suggest themselves to skilled persons having the benefit of this disclosure. Reference will now be made in detail to implementations as illustrated in the accompanying drawings. The same reference indicators will generally be used throughout the drawings and the following detailed description to refer to the same or like parts. It should be appreciated that the drawings are generally not drawn to scale, and at least some features of the drawings have been exaggerated for ease of illustration. 
     Embodiments of the invention can relate to apparatus, systems and methods for forming a housing having a thin glass member for an electronic device. In one example, the glass member may be an outer surface of an electronic device. The glass member may for example correspond to a glass cover that helps form part of a display area of an electronic device (i.e., situated in front of a display either as a separate part or integrated within the display). Alternatively or additionally, the glass member may form a part of the housing. For example, it may form an outer surface other than in the display area. 
     The apparatus, systems and methods for improving strength of thin glass are especially suitable for glass covers, or displays (e.g., LCD displays), assembled in small form factor electronic devices such as handheld electronic devices (e.g., mobile phones, media players, personal digital assistants, remote controls, etc.). The glass can be thin in these small form factor embodiments, such as less than 3 mm, or more particularly between 0.5 and 2.5 mm, or even more particularly between 0.3 and 1.0 mm. The apparatus, systems and methods can also be used for glass covers or displays for other devices including, but not limited to including, relatively larger form factor electronic devices (e.g., portable computers, tablet computers, displays, monitors, televisions, etc.). The glass can also be thin in these larger form factor embodiments, such as less than 5 mm, or more particularly between 0.5 and 3 mm, or even more particularly between 0.3 and 2.0 mm. 
     Embodiments are discussed below with reference to  FIGS. 1-11 . However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these figures is for explanatory purposes as the invention extends beyond these limited embodiments. 
       FIG. 1  a flow diagram of a housing formation process  100  according to one embodiment. The housing formation process  100  can operate to produce a housing for an electronic device, or at least a portion of such a housing. 
     The housing formation process  100  can initially obtain  102  a glass member. A top surface of the glass member can represent an outer surface for the housing, and the bottom surface of the glass member is an inner surface that is not exposed. The glass member can serve as a significant outer surface for the housing. For example, the glass member can correspond to a top surface for the housing. Alternatively or additionally, the glass member can correspond to a bottom surface for the housing. The glass member is typically thin, particularly when used with portable electronic devices. In one embodiment, the glass member has a thickness of less than 5 mm, or more particularly less than 1 mm. 
     After the glass member has been obtained  102 , mounting brackets can be attached  104  to a peripheral region on the bottom surface of the glass member. The mounting brackets can be attached to the bottom surface of the glass member using an adhesive. The adhesive can, for example, by provided as a film or layer. Also, the manner by which the adhesive is deposited can vary. In one implementation, the adhesive can be deposited by forming a peripheral pattern of adhesive that can be placed on the bottom surface of the glass member so as to provide adhesive at the regions on the bottom surface of the glass member where the mounting brackets are to be placed. In another implementation, the adhesive can be screen printed on appropriate peripheral portions on the bottom surface of the glass member. In still another embodiment, the adhesive can be applied to the surface of the mounting brackets that is to be secured to the bottom surface of the glass member. 
     After the mounting brackets have been attached  104 , a touch screen assembly can be attached  106  to a central region of the bottom surface of the glass member. The touch screen assembly can include a plurality of touch and display components that are laminated together to implement a touch screen. The touch and display components can, for example, include a display technology layer (e.g., LCD panel), a sensing layer (e.g., touch sensors) and/or a back light component. 
     The touch screen assembly can be attached  106  using an adhesive. The adhesive can, for example, by provided as film or layer. Also, the manner by which the adhesive is deposited can vary. In one implementation, the adhesive can be deposited by forming a pattern of adhesive (e.g., translucent adhesive) that can be placed on the bottom surface of the glass member so as to provide adhesive at the bottom surface of the glass member where the touch screen assembly is to be placed. The adhesive can additionally or alternatively be deposited on the top surface of the touch screen assembly. In another implementation, the adhesive can be screen printed or sprayed on appropriate portion of the bottom surface of the glass member and/or a top surface of the touch screen assembly. 
     Next, after the touch screen assembly has been attached  106 , a frame can be attached  108  such that the frame is adjacent to the bottom surface of the touch screen assembly. The frame being attached  108  can serve to protect the touch screen assembly from damage and can provide structural stiffness to the housing for the electronic device. The frame can be attached  108  to the mounting brackets or side members of the housing for the electronic device. In one embodiment, the frame can be attached  108  using any of a variety of means, such as adhesive, screws, snaps or welds. In some embodiment, the frame need not be included. 
     After the frame has been attached  108 , the resulting display assembly, including the glass member, the mounting brackets, the touch screen assembly and the frame can be secured to the housing of the electronic device. For example, the resulting display assembly can be secured  110  to the housing of the electronic device by way of the mounting brackets and/or the frame. Following the block  110 , the housing formation process  100  can end. 
       FIG. 2A  is a cross-sectional view of an electronic device housing  200  according to one embodiment.

The touch and display components can, for example, include a display technology layer (e.g. LCD panel), a sensing layer (e.g. touch sensors) and/or a back light component. 
     The touch screen assembly can be attached  506  using an adhesive. The adhesive can, for example, by provided as film or layer. Also, the manner by which the adhesive is deposited can vary. In one implementation, the adhesive can be deposited by forming a pattern of adhesive (e.g. translucent adhesive) that can be placed on the bottom surface of the glass member so as to provide adhesive at the bottom surface of the glass member where the touch screen assembly is to be placed. The adhesive can additionally or alternatively be deposited on the top surface of the touch screen assembly. In another implementation, the adhesive can be screen printed or sprayed on appropriate portion of the bottom surface of the glass member and/or a top surface of the touch screen assembly. 
     Next, after the touch screen assembly has been attached  506 , mounting brackets can be attached  508  to the frame. In one embodiment, the frame can be attached  508  to the frame using any of a variety of means, such as adhesive, screws, snaps or welds. 
     After the mounting brackets have been attached  508 , the resulting display assembly, including the glass member, the mounting brackets, the touch screen assembly and the frame can be secured  550  to the housing of the electronic device. For example, the resulting display assembly can be secured to the housing of the electronic device by way of the mounting brackets and/or the frame.

In one implementation, the adhesive can be deposited by forming a peripheral pattern of adhesive that can be placed on the bottom surface of the glass member so as to provide adhesive at the regions on the bottom surface of the display screen assembly where the mounting brackets are to be placed. In another implementation, the adhesive can be screen printed on appropriate peripheral portions on the bottom surface of the glass member. In still another embodiment, the adhesive can be applied to the surface of the mounting brackets that is to be secured to the bottom surface of the display screen assembly. 
     After the mounting brackets have been attached  706 , a frame can be attached  708  such that the frame is adjacent to the bottom surface of the display screen assembly. The frame being attached  708  can serve to protect the display screen assembly from damage and can provide structural stiffness to the housing for the electronic device. The frame can be attached  708  to the mounting brackets or side members of the housing for the electronic device. In one embodiment, the frame can be attached  708  using any of a variety of means, such as adhesive, screws, snaps or welds. In some embodiment, the frame need not be included. 
     After the frame has been attached  708 , the resulting display assembly, including the glass member, the display screen assembly, the mounting brackets and the frame can be secured to the housing of the electronic device. For example, the resulting display assembly can be secured  710  to the housing of the electronic device by way of the mounting brackets and/or the frame. Following the block  710 , the housing formation process  700  can end.
