Abstract
The present disclosure relates to an electronic device and a method capable of allowing a pressure sensor to accurately sense a pressure value regardless of environmental factors, a change in elasticity of an elastic layer, and a change in an inter-electrode layer gap, wherein the method may include determining, using the pressure sensor, a pressure level while there is no external pressure against the front plate and adjusting at least one threshold level for the electronic device to use when there is an external pressure against the front plate, based at least in part on the determined pressure level.
Claims20
An electronic device, comprising:
- a housing including a front plate and a back plate facing a direction opposite the front plate;
- a display panel interposed between the front plate and the back plate, and exposed through the front plate;
- a mid-plate interposed between the display panel and the back plate;
- a pressure sensor including a first conductive plate interposed between the display panel and the mid-plate, and a second conductive plate interposed between the first conductive plate and the mid-plate and spaced from the first conductive plate;
- an elastic member comprising an elastic material interposed between the second conductive plate and the mid-plate, and attached to the mid-plate;
- a processor disposed in the housing and electrically connected to the display panel and the pressure sensor;
- and
- a memory disposed in the housing and electrically connected to the processor, wherein the memory stores instructions that, when executed by the processor, cause the electronic device to:
- determine, using the pressure sensor, a pressure level while there is no external pressure against the front plate;
- and
- adjust at least one threshold level for the electronic device to use when there is an external pressure against the front plate, based at least in part on the determined pressure level.
A method for sensing, by an electronic device, a pressure, the electronic device including a display panel interposed between a front plate and a back plate and exposed through the front plate, a mid-plate interposed between the display panel and the back plate, a pressure sensor including a first conductive plate interposed between the display panel and the mid-plate and a second conductive plate interposed between the first conductive plate and the mid-plate and spaced from the first conductive plate, and an elastic member comprising an elastic material interposed between the second conductive plate and the mid-plate and attached to the mid-plate, the method comprising:
- determining a pressure level, using the pressure sensor while there is no external pressure against the front plate;
- and
- adjusting at least one threshold level for the electronic device to use when there is an external pressure against the front plate, based at least in part on the determined pressure level.
A non-transitory computer-readable recording medium having stored thereon instructions that, when executed by at least one processor of an electronic device, cause the electronic device to perform at least one operation, the electronic device including a display panel interposed between a front plate and a back plate and exposed through the front plate, a mid-plate interposed between the display panel and the rear plate, a pressure sensor including a first conductive plate interposed between the display panel and the mid-plate and a second conductive plate interposed between the first conductive plate and the mid-plate and spaced from the first conductive plate, an elastic member comprising an elastic material interposed between the second conductive plate and the mid-plate and attached to the mid-plate, and a processor electrically connected to the display panel and the pressure sensor,
- the at least one operation comprising:
- determining, using the pressure sensor, a pressure level while there is no external pressure against the front plate;
- and
- adjusting at least one threshold level for the electronic device to use when there is an external pressure against the front plate, based at least in part on the determined pressure level.
