Abstract
An information terminal capable of switching display and non-display of images by strain. The information terminal includes a display portion and a strain sensor. The display portion includes a liquid crystal element, a light-emitting element, and a first and a second transistors. The strain sensor includes a strain sensor element and a resistor. The first transistor has a function of controlling current flowing into the light-emitting element. The strain sensor element has a function as a variable resistor. A first terminal of the strain sensor element is electrically connected to a first terminal of the resistor. A gate of the first transistor is electrically connected to a first terminal of the strain sensor element via the second transistor.
Claims28
An information terminal comprising:
- a touch sensor;
- and
- a display panel capable of display information input via the touch sensor, the display panel comprising:
- a reflection-type liquid crystal element;
- a light-emitting element;
- and
- a strain sensor;
- and
- wherein the information terminal is configured so that light emitted by the light-emitting element is sighted by a user of the information terminal when the strain sensor does not sense strain whereas light reflected by the reflection-type liquid crystal element is sighted by the user of the information terminal when the strain sensor senses strain.
An information terminal comprising:
- a touch sensor;
- and
- a display panel capable of display information input via the touch sensor, the display panel comprising:
