<p>PURPOSE:To provide the multi-display device whose display screen can be seen by a person other than an operator. CONSTITUTION:A character 'B' is displayed on a 1st flat plate type display and a character 'A' is displayed on a 2nd flat plate type display. When the 2nd flat plate type display is fallen to the back side and the character 'A' is inverted. So that the character and a picture on the 2nd flat plate type display can be seen in an erect state, a sensor detects the angle between the 1st flat plate type display and 2nd flat plate type display and if the display is fallen to the back side, pixel data D0, D1...Dn are written in addresses (n), (n-1)...0, but when the display is not fallen to the back side, on the other hand, the pixel data D0, D1...Dn are written in the addresses 0, 1...(n). Read addresses are generated in the order of 0, 1...(n).</p> |
