Portable display apparatus

Abstract

Stacked panel housings are stretched to join displays to each other to form a single screen, the stacked panel housings are stretched and two displays are jointed to each other to form a single screen. Horizontal sliding means and vertical moving means can be provided so as to displace the stacked displays to be flush with each other. A portable display device is provided which has at least two panel housings vertically stacked and displays mounted on the panel housings, respectively, in which the displays horizontally slide and then vertically move so as for the displays of the panel housings to be contiguous to each other. When the displays are contiguous to each other, the distance between the displays is in the range of 0.1 mm to 5 mm and a joint between the displays is provided with a lid.

         4 . The portable display device according to  claim 2 , wherein when the two panel housings are similar to each other in thickness, a battery and a main controller are mounted on the different panel housings. 
     
     
         5 . The portable display device according to  claim 1 , wherein when a part of the input units to which information is input is defined as an active area, the active area is formed closer to a joint than the other side of the joint. 
     
     
         6 . The portable display device according to  claim 5 , wherein the distance between the active area of the input units and the boundary of the input units in the joint is in the range of 2.5 mm to 3.5 mm. 
     
     
         7 . The portable display device according to  claim 1 , wherein a protrusion is formed between the displays and the corresponding input units to support the corresponding input units. 
     
     
         8 . The portable display device according to  claim 1 , wherein an intermediate plate is disposed between the displays and the corresponding input units to support the corresponding input units. 
     
     
         9 . The portable display device according to  claim 1 , further comprising a driver that drives the displays, wherein when the joint of the respective displays is located on the right side, the driver is located on the upper side or lower side thereof. 
     
     
         10 . The portable display device according to  claim 9 , further comprising supply lines that connect the driver and electrodes in the respective displays, wherein more of the supply lines are disposed on the side opposite to the joint than the side of the joint. 
     
     
         11 . The portable display device according to  claim 9 , further comprising supply lines that connect the driver and electrodes in the respective displays, wherein the supply lines are disposed on the side opposite to the joint. 
     
     
         12 . The portable display device according to  claim 9 , further comprising a connector that connects the displays, wherein the connector is disposed on the side opposite to the joint. 
     
     
         13 . The portable display device according to  claim 9 , wherein a first input unit outputs a control signal corresponding to a first display and a second input unit outputs a control signal corresponding to a second display so as to use the two input units as a single input unit. 
     
     
         14 . The portable display device according to  claim 2 , wherein a button image is displayed on the display mounted on the upper panel housing in a state where the two panel housings are stacked. 
     
     
         15 . The portable display device according to  claim 14 , wherein when the two panel housings are stretched, an input keyboard image is displayed on one display. 
     
     
         16 . The portable display device according to  claim 1 , wherein when the panel housings slide, a plate-like structure formed of metal or alloy supports the panel housings to slide.
