Abstract
Disclosed is an erasable display apparatus including a heat-sensitive medium 1 having a hysteresis effect relative to temperature change. This display apparatus comprises an endless broad-width heat-sensitive display medium 1, driving means 2 for rotating and transferring the heat-sensitive display medium 1, a first heating member 3 for thermally recording information to be displayed on the heat sensitive display medium 1, a plane transparent panel heater 4 disposed on the back of the display surface contiguously to the heat-sensitive display medium 1, lighting means 5 disposed on the back of the transparent heat-insulating member 4 to illuminate the display surface, a color filter 6 disposed in front of the display surface and cooling means 7 for erasing the information recorded on the heat-sensitive display medium 1 after display. By this display apparatus, a display can be accomplished at a high density and the displayed picture quality can be enhanced. This display apparatus can be used repeatedly at a high frequency.
