Several definitions that apply throughout this disclosure will now be presented.
The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “outside” refers to a region that is beyond the outermost confines of a physical object. The term “inside” indicates that at least a portion of a region is partially contained within a boundary formed by the object. The term “substantially” is defined to be essentially conforming to the particular dimension, shape or other word that substantially modifies, such that the component need not be exact. For example, substantially cylindrical means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising”, when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like.

The third receiving portion 423 can be smaller than the second receiving portion 422, configured to receive the back light module 30 (shown in
In assembly, the lamp plate 34 can be installed on the third bent portion 417, and the reflective sheet 33 can be attached to the support portion 411 between the second bent portion 416 and the third bent portion 417. Then, the light guiding plate 32 and the optical film 31 can be positioned above the reflective sheet 33 in order, and the first protrusion portions 3111 (shown in
As the housing 40 can include the metal element 41 and the plastic portion 42 integrally formed with the metal element 41 by the method of insert molding, the housing 40 can have a low average density and light weight. Additionally, the metal element 41 can include the closed sidewall 414 and the first bent portion 415 connected to the closed sidewall 414 by the connecting portion 418, which can enhance the mechanical properties of the housing 40. Thus, the housing 40 and the portable device 100 having the housing 40 can have the reserved mechanical properties. Further more, the display panel 20, optical panel 31, and the light guiding plate 32 can be directly accommodated in the housing 40 to form an integrated unity. Therefore, the portable device 100 having the housing 40 does not need an extra frame holding the display module 20 or an extra metal plate fastening the backlight module 30, so that portable device 100 can have low production cost and thin profile.
