TABLETTE DOTÉE D'UNE ANTENNE DE LIGNE À STRUCTURE AMÉLIORÉE
(KO)
개선된 구조의 라인 안테나를 갖는 타블렛
Abstract:
(EN)
A tablet of the present invention comprises: a loop antenna having a closed loop shape forming a circumference of an electronic pen sensing region; a plurality of line antennas arranged in parallel with each other into the teeth of a comb shape; a line selection circuit to which the other ends of the plurality of line antennas are coupled; and a coordinate sensing circuit for controlling the selecting operation of the line selection circuit and determining the position of the electronic pen based on the selected line antenna using the induced voltage presented in a differential output by the magnetic force emitted from the electronic pen. Here, the plurality of line antennas arranged in parallel with each other are divided into at least two groups, wherein a first group has one end connected to the loop antenna and the other end coupled to the line selection circuit, and a second group has one end coupled to the line selection circuit and the other end connected to the loop antenna.
(FR)
La présente invention porte sur une tablette qui comprend : une antenne cadre présentant une forme de boucle fermée formant une circonférence d'une région de détection de stylo électronique ; une pluralité d'antennes de ligne agencées en parallèle l'une à l'autre dans les dents d'une forme de peigne ; un circuit de sélection de ligne auquel les autres extrémités de la pluralité d'antennes de ligne sont couplées ; et un circuit de détection de coordonnée pour commander l'opération de sélection du circuit de sélection de ligne et déterminer la position du stylo électronique sur la base de l'antenne de ligne sélectionnée à l'aide de la tension induite présentée dans une sortie différentielle par la force magnétique émise par le stylo électronique. Ici, la pluralité d'antennes de ligne agencées en parallèle l'une à l'autre sont divisées en au moins deux groupes, un premier groupe ayant une extrémité reliée à l'antenne cadre et l'autre extrémité couplée au circuit de sélection de ligne, et un second groupe ayant une extrémité couplée au circuit de sélection de ligne et l'autre extrémité reliée à l'antenne cadre.

본 발명에 따른 타블렛은, 전자펜 감지 영역의 둘레를 형성하는 폐루프 형태의 루프 안테나와; 빗살 모양으로 서로 평행하게 배치된 복수의 라인 안테나와; 상기 복수의 라인 안테나의 타단들이 결합되어 있는 라인 선택 회로와; 상기 라인 선택 회로의 선택 동작을 제어하고 상기 전자펜에서 방출하는 전자기력에 의해 상기 차동 출력에서 나타나는 유도 전압을 이용하여 상기 선택된 라인 안테나를 기준으로 상기 전자펜의 위치를 판정하는 좌표 감지 회로를 포함한다. 이때, 서로 평행한 상기 복수의 라인 안테나는 적어도 2개의 군으로 분할되고, 제1군은 일단측이 상기 루프 안테나와 연결되고 타단측이 상기 라인 선택 회로에 결합되고, 제2군은 일단측이 상기 라인 선택 회로에 결합되고 타단측이 상기 루프 안테나와 연결된 것을 특징으로 한다.
