[0004] 2. Description of the Related Art

[0005] A conventional portable computer has a display module, and a main computer module connected directly to the display module to form a single unit for outdoor use. However, when the conventional portable computer is used indoors, the relative position between the display module and the main computer module is severely limited due to the single unit configuration, thereby resulting in inconvenience during use. In addition, when the display module is to be replaced with a larger one or when the main computer module is to be upgraded, the entire portable computer may have to be replaced, thereby resulting in unnecessary waste.

[0006] Therefore, the main object of the present invention is to provide a portable computer that has a detachable display module so as to facilitate replacement.

[0007] Another object of the present invention is to provide a computer display assembly that can be easily connected to a main computer module of a desktop computer or a portable computer so as to result in increased convenience.

The top surface is formed with an inwardly and longitudinally extending insert groove adjacent to the first side surface. The first side surface is formed with a slot communicated with the insert groove. The main computer module further includes a first connector mounted on the main housing.

[0010] The liquid crystal display module includes a display housing, a second connector, a pivot retainer and an anchoring post. The second connector is mounted on the display housing, and is connected electrically and removably to the first connector. The pivot retainer has a first pivot portion secured to the display housing, and a second pivot portion coupled rotatably and co-axially to the first pivot portion. The anchoring post extends radially from the second pivot portion. The anchoring post is inserted removably into the insert groove from the top surface of the main housing, thereby coupling rotatably the display housing to the main housing.

[0011] The latch unit is movably disposed in the insert groove and is accessible via the slot in the main housing so as to be operable for movement between a latching position, where the latch unit engages the anchoring post to prevent removal of the anchoring post from the insert groove, and a releasing position, where the latch unit disengages the anchoring post to permit removal of the anchoring post from the insert groove.

[0012] According to another aspect of the present invention, a computer display assembly is adapted for use with a main computer module, and includes a display stand and a liquid crystal display module.

[0013] The display stand includes a stand housing formed with an insert groove, and first and second connectors mounted on the stand housing. The first connector is adapted to be connected electrically to the main computer module.

[0014] The liquid crystal display module includes a display housing, a third connector, a pivot retainer and an anchoring post. The third connector is mounted on the display housing, and is connected electrically and removably to the second connector. The pivot retainer has a first pivot portion secured to the display housing, and a second pivot portion coupled rotatably and co-axially to the first pivot portion.
