Abstract
An electronic device including an input sensing module including a sensing surface to which a palm is input, the sensing surface having a three-dimensional shape, and a control module comparing user palm information with input palm information sensed by the input sensing module to output an authentication signal when a number of data points of the user palm information consistent with the stored input palm information is equal to or greater than a predetermined number.
Claims15
An input sensing module comprising:
- a flexible base member comprising a three-dimensional base surface;
- and
- a plurality of sensing electrodes disposed on the flexible base member;
- wherein:
- the flexible base member comprises a first base portion having a first non-flat average curvature and a second base portion having a second non-flat average curvature smaller than the first average curvature;
- the plurality of sensing electrodes comprise first sensing electrodes disposed on the first base portion and second sensing electrodes disposed on the second base portion, the first sensing electrodes having a first pitch, and the second sensing electrodes having a second pitch greater than the first pitch;
- the first pitch is defined by a sum of a first width of an electrode of the first sensing electrodes and a first distance between the first sensing electrodes adjacent to each other;
- and
- the second pitch is defined by a sum of a second width of an electrode of the second sensing electrodes and a second distance between the second sensing electrodes adjacent to each other.
