Abrégé
(EN)

A user input system (1), comprising a coil (44) for generating an alternating magnetic field, a cordless pen (9), and a capacitive current measuring arrangement or an electric field sensing arrangement. The cordless pen (9) comprises a resonant circuit (34), a conductive housing (28) and a conducting tip (36). The alternating magnetic field induces an alternating voltage in the resonant circuit (34), which is coupled to the conducting tip (36). The capacitive current measuring arrangement comprises a resistive sheet (40) and current measuring means (42) arranged to measure a capacitive current flowing from the conducting tip (36) to the resistive sheet (40). The electric field sensing arrangement comprises an electric field sensing reception electrode (47) and current sensing circuitry (48) for determining a current excited in the electric field sensing reception electrode (47) by an electric field generated by the conducting tip (36). In each case the currents are sensed at plural locations and the differing magnitudes compared to determine a position of the conducting tip (36) relative to the plural locations. The system may also be adapted to sense a user's finger (8). The user input system (1) may be incorporated in a display device, for example an active matrix liquid crystal display device (4).

(KO) 본 발명은 사용자 입력 시스템(1)에 관한 것으로서, 이 시스템은 교류 자계를 생성하는 수단(44)과, 무선 펜(9)과, 용량성 전류 측정 장치 또는 전계 감지 장치를 포함한다. 이 무선 펜(9)은 공진 회로(34), 도전성 하우징(28) 및 도전성 팁(36)을 포함한다. 교류 자계가 도전성 팁(36)에 접속된 공진 회로(34) 내에 교류 전압을 유도한다. 용량성 전류 측정 장치는 저항 시트(40) 및 도전성 팁(36)에서 저항 시트(40)로 흐르는 용량성 전류를 측정하는 전류 측정 수단(42)을 포함한다. 전계 감지 장치는 전계 감지 수신 전극(47)과 도전성 팁(36)에 의해 생성된 전계에 의해 전계 감지 수신 전극(47) 내에 유도된 전류 값을 결정하는 전류 감지 회로(48)를 포함한다. 각 경우에 전류는 다수의 위치에서 감지되며 이로써 감지된 상이한 전류 크기가 비교되어 다수의 위치에 대한 도전성 팁(36)의 위치를 결정한다. 이 시스템은 또한 사용자의 손가락(8)을 감지하도록 적응된다. 사용자 입력 시스템(1)은 가령 액티브 매트릭스 액정 디스플레이 디바이스(4)와 같은 디스플레이 디바이스 내에 내장될 수 있다.
