Abstract
A method of manufacturing a digitizer includes forming a circuit layer that detects an input, forming a magnetic field shielding layer that contains disoriented magnetic powder, disposing an adhesive between the circuit layer and the magnetic field shielding layer, and hot pressing the circuit layer and the magnetic field shielding layer so as to orient the magnetic powder.
Claims11
An electronic device comprising:
- a magnetic field sensor configured to detect first input based on a magnetic field;
- a display disposed on a top of the magnetic field sensor, wherein the display is configured to display a screen;
- and
- a capacitive sensor layer disposed on a top of the display, wherein the capacitive sensor layer is configured to detect a second input based on a change in a capacitance,
- wherein the magnetic field sensor comprises:
- a first conductive layers a magnetic field shielding layer formed between the first conductive layer and a first cover layer, wherein the magnetic field shielding layer is configured to reduce an intensity of a magnetic field reaching the first conductive layer, and the first cover layer in contact with the magnetic field shielding layer, and
- wherein the magnetic field shielding layer is formed by hot pressing the first cover layer onto the first conductive layer while a mixture of an adhesive resin and a disoriented magnetic powder is disposed between the first cover layer and the first conductive layer, wherein the hot pressing causes the disoriented magnetic powder to be oriented and attaches the first cover layer to the first conductive layer, and wherein the magnetic field shielding layer is the mixture including oriented magnetic powder.
