Abstract
A mobile terminal includes a display unit configured to display an image and comprising an OLED pixel module emitting light and a light non-transmitting layer formed therebelow; a fingerprint recognition sensor configured to recognize a fingerprint by receiving, when the light emitted from the OLED pixel module is reflected by a finger, the reflected light; a sensor insertion space formed by perforating a part of the light non-transmitting layer, the fingerprint recognition sensor being inserted into the sensor insertion space; and a force sensor disposed at a side surface of the fingerprint recognition sensor and configured to measure a magnitude of pressure applied to the force sensor.
Claims22
A mobile terminal comprising:
- a display unit configured to display an image and comprising an OLED pixel module emitting light and a light non-transmitting layer formed therebelow;
- a fingerprint recognition sensor configured to recognize a fingerprint by receiving, when the light emitted from the OLED pixel module is reflected from a finger, the reflected light, the fingerprint recognition sensor including an upper surface facing the display unit, a lower surface opposite to the upper surface, and a side surface extending between the upper surface and the lower surface, the side surface being oriented not parallel to the display unit;
- a sensor insertion space formed by perforating a part of the light non-transmitting layer, the fingerprint recognition sensor being inserted into the sensor insertion space;
- and
- a force sensor disposed to face and surround the side surface of the fingerprint recognition sensor in a first plane, wherein the force sensor is configured to measure pressure applied to the force sensor in a second plane perpendicular to the first plane,
- wherein the force sensor comprises:
- a flexible printed circuit board having a shape transformable by the applied pressure;
- and
- strain gauges attached to each of upper and lower surfaces of the flexible printed circuit board, and
- wherein the force sensor is configured to measure the applied pressure through change in resistance of the strain gauges.
