Patent ID: 7088589

Claim:
A mechanical and automatic liquid crystal display device comprising a case, an extendable deck, a coupling mechanism, a display panel holding mechanism and an upward folding adjustment device, wherein: the case is hollow and has a window and a first channeling mechanism and a second channeling mechanism located respectively on two sides corresponding to each other to guide the extendable deck to retract inwards or extend outwards at desired locations; the extendable deck has a front side pivotally engaged with the display panel holding mechanism and is coupled with the first channeling mechanism and the second channeling mechanism for positioning; the coupling mechanism is located on one side of the extendable deck to control folding, latching and releasing of the display panel holding mechanism; the display panel holding mechanism has a panel to hold a LCD panel; and the upward folding adjustment device is located in the display panel holding mechanism and connected to the extendable deck and has an upward folding actuation assembly guiding the display panel holding mechanism for folding upwards and storing, the upward folding adjustment device selectively adjusting the display panel holding mechanism to one of a plurality of turning elevation angles and returning the display panel holding mechanism to a previously selected turning elevation angle selected from the plurality of turning elevation angles; wherein the LCD panel is foldable upwards and storable in the case; wherein the upward folding actuation assembly includes two dampers, two sliding members, and an elevation angle push plate.
