FIELD OF THE INVENTION
The present invention generally relates to a structure of the display module of a portable computer, more particularly to an enhanced structure for a large display module of a portable computer.
BACKGROUND OF THE INVENTION
In recent years, electronics and information industries are blooming, and related products becomes more precise day after day. In addition to the pursuance of a computing unit with faster and more powerful computing functions and various peripherals to satisfy user requirements in the personal computer area, a lightweight, thin, short and compact portable computer is also a key developing area in the industry.
Since a portable computer emphasizes on its portability, therefore the portable computer may be impacted by objects in the external environment during its transportation and use or compressed excessively due to the negligence of users, and thus resulting cracks or damages to a flat display module.
In R.O.C. Patent Application No. 90212717 entitled “Portable computer and its collision buffer device” filed on Jul. 26, 2001, a collision buffer device is installed at the edges and corners of the casing of a display of a portable computer. If the portable computer is collided by accident, the buffer device will provide a buffer function to the portable computer and protect the display and its internal components, and thus preventing the display from being damaged or cracked by the collision. However, the technology disclosed in such prior art only emphasizes on the design for protecting the edges and corners of the display panel, but does not provide a solution for protecting the display from being damaged by external forces coming from other directions.
In R.O.C. Patent Application No. 90204109 entitled “Enhanced frame structure of flat display” filed on Dec. 4, 2000, a metal frame is mounted onto the periphery of a liquid crystal display module to fix the components of the liquid crystal display. The metal frame according to such prior art usually adds a scraggy groove thereon by a sheet metal manufacturing method to enhance its structure strength. However, such metal frame tends to have a thin design to cope with the lightweight requirement, and thus lowering the strength and weakening the protection effect of the display panel.
Present consumers have high requirements on the size of a display panel of a portable computer, and the display panel is getting larger and larger. With the consideration of thin and lightweight characteristics of portable computers, the installation of a large display panel model of a portable computer has a much stricter requirement on the structural strength than that of a small display panel.
SUMMARY OF THE INVENTION
Therefore, it is a primary objective of the present invention to provide a structure for the display panel of a portable computer, particularly an enhanced structure for the large display panel of a portable computer, which installs a hard frame around the periphery of a large screen of a portable computer to improve the structural strength of the screen and prevent the display panel from being damage or deformed caused by an external force or a torque of the hinge.
Another objective of the present invention is to use a hard frame to provide reinforcements and protections to the display module and overcome the shortcomings of the insufficient structural strength for the prior art large display module of a notebook computer.
A further objective of the present invention is to connect the frame with the screen hinge so as to diversify the torque and stress of a prior art hinge and extend the longevity of the hinge of a notebook computer. Since the prior arts generally emphasize on a solution for the computer hinge, the effect is insignificant and cannot be compared with the effect of the present invention that directly transfers the stress of the hinge onto an additional hard frame.
Another further objective of the present invention is to install an arm on the sides of the hard frame without ruining the external appearance of the computer display.

In FIGS. 4 and 7, the hard frame fixing section 231 of the first hinge 23 and the hard frame fixing section 331 of the second hinge 33 are through slots. In FIG. 2, the first hinge fixing section 114 and the second hinge fixing section 124 of the hard frame 1 separately have a groove hole with a spiral groove, and thus the first hinge fixing section 114 of the hard frame 1 and the hard frame fixing section 231 of the first hinge 23 are secured by screws; and the second hinge fixing section 124 of the hard frame 1 and the hard frame fixing section 331 of the second hinge 33 are also secured by screws.
Compared with the prior arts, the structure of the present invention connects the hard frame 1 with the first hinge 23 and the second hinge 33 to directly and effectively diversify the torque and stress of the hinge and extend the longevity of the hinge of a notebook computer. Most prior arts emphasize on the hinge, but the effect is very limited, which cannot achieve the effect of spreading the stress of the hinge directly onto an external hard frame 1 as the present invention does.
In FIG. 1, the first arm fixing sections 111, 112, 113 and the second fixing section 114, 115, 116 of the hard frame are protruded components. In FIGS. 4 and 7, the hard frame fixing section 211, 212, 213 of the first arm 21 and the hard frame fixing sections 311, 312, 313 of the second arm 31 are latch groove components, such that the protruded components and the latch groove components can be latched with each other.
Referring to FIG. 3, a cross-sectional view of Section X1-X1 is illustrated. In FIG. 3, the protruded component includes a root section 131, a neck section 132 and a blocking section 133. The root section 131 is embedded into the slot 130 at the internal side of the hard frame 1; the neck section 132 is latched into the latch groove components of the hard frame fixing sections 211, 212, 213 of the first arm 21 and the hard frame fixing sections 311, 312, 313 of the second arm 31; and the blocking section 133 maintains the latch condition between the protruded components and the latch groove components. Preferably, the root section 131 of the protruded components is surrounded by a spiral groove that can be embedded spirally into the hard frame slot 130.
In FIGS. 10 and 11, the structure of the present invention completely hides the fixing sections and components without ruining the external appearance by connecting the hard frame 1 with the first arm 21 and second arm 31 as well as installing an upper panel 5 of the panel module.
Further, the hard frame 1 is preferably made of an aluminum alloy, an aluminum-magnesium alloy or a titanium alloy. Although the invention focuses on the design of a large display module for notebook computers, yet it is not limited to the large display module, but also provides a strong structure for display modules other than the large ones.
While the invention has been described by way of example and in terms of a preferred embodiment, it is to be understood that the invention is not limited thereto. To the contrary, it is intended to cover various modifications and similar arrangements and procedures, and the scope of the appended claims therefore should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements and procedures.
