ELECTRONIC DEVICE AND COORDINATE DETECTION METHOD |
| 摘要 |
An electronic device includes a housing, a planar display section, a planar transparent member, a touch panel layer which detects two-dimensional coordinates of an indicator having a predetermined conductivity along a surface of the display section and a vertical distance to the indicator, and an acceleration detection section which detects at least one of an acceleration of the housing and an acceleration of the transparent member. The two-dimensional coordinates are determined as effective coordinates when the vertical distance is equal to or smaller than a first value. The two-dimensional coordinates are determined as the effective coordinates when the vertical distance is more than the first value and is equal to or smaller than a second value more than the first value, and the acceleration detection section detects a predetermined acceleration. |

1. An electronic device comprising:
a housing; a planar display section disposed in the housing; a planar transparent member having a predetermined transmittance, disposed so as to overlap the display section, and having a part exposed from the housing; a touch panel layer disposed so as to overlap the display section and disposed between the display section and the transparent member, and configured to detect two-dimensional coordinates of an indicator having a predetermined conductivity along a surface of the display section and a vertical distance to the indicator from the surface of the display section; and an acceleration detection section configured to detect at least one of an acceleration of the housing and an acceleration of the transparent member, wherein the two-dimensional coordinates are determined as effective coordinates when the vertical distance is equal to or smaller than a first value; and wherein the two-dimensional coordinates are determined as the effective coordinates when the vertical distance is more than the first value and is equal to or smaller than a second value more than the first value, and the acceleration detection section detects a predetermined acceleration. |
