A display unit has a flexible display section, a detection section for detecting a deflection amount and a deflection direction of the display section, a determination section for determining a visible portion and a non-visible portion of the display section based on the deflection amount and the deflection direction, and a control section for controlling display contents of the display section. The control section either prevents an image display on the non-visible portion or displays one of a fixed image or a pre-set moving image on the non-visible portion. The display unit also includes a displacement sensor located in the same region as the display section.
1. A display unit, comprising:
a display section that has flexibility; and
a plurality of sensors configured to:
detect a deflection amount and a deflection direction that corresponds to the flexibility of the display section;
a central processing unit (CPU) configured to:
determine a visible portion and a non-visible portion of the display section based on the deflection amount and the deflection direction, wherein the deflection direction is detected by at least three displacement sensors of the plurality of sensors, respectively disposed at both end locations and a center location on an X-axis on a rear side of the display section, wherein the CPU is further configured to recognize a projection area, based on a distance between two or more displacement sensors of the at least three displacement sensors, as the visible portion; and
reduce a frequency to rewrite display contents of the non-visible portion of the display section.
2. The display unit according to claim 1 ,
wherein the CPU is configured to one of prevent an image display on the non-visible portion or display one of a fixed image or a pre-set moving image on the non-visible portion.
3. The display unit according to claim 1 ,
wherein the CPU is configured to display one of a fixed image or a pre-set moving image on the non-visible portion.
4. The display unit according to claim 1 , further comprising an A/D conversion section configured to:
convert the deflection amount into a digital value, and
a storage section configured to store a set value and the digital value.
5. The display unit according to claim 1 , wherein the at least three displacement sensors are located in the same region as the display section.
6. The display unit according to claim 5 ,
wherein the at least three displacement sensors comprise a resistance sensor configured to detect a position of a curve that divides the display section into the visible portion and the non-visible portion.
7. The display unit according to claim 5 ,
wherein the at least three displacement sensors comprise at least three acceleration sensors.
8. The display unit according to claim 5 ,
wherein the at least three displacement sensors comprise one or more of a photosensor, a temperature sensor, or a pressure sensor.
