    • PURPOSE: A touch screen device is provided to ignore ghost points when at least two touch points exist in a touch area, thereby determining the coordinates of an accurate touch point. CONSTITUTION: A first light transceiving unit(131) and a second light transceiving unit(132) emits light onto a touch area. The first light transceiving unit and the second light transceiving unit detect light reflected by a mirror part and a retro reflective part. An angle extracting unit(14) calculates light emitting angles about a location where reflected light is not received by at least one of the first and second light transceiving units. A coordinate generating unit(15) calculates the coordinates of a location where light routes cross each other. The light routes correspond to light emitting angles.
    • 目的:提供触摸屏设备,以便在触摸区域中至少存在两个触摸点时忽略虚拟点,从而确定准确的触摸点的坐标。 构成:第一光收发单元(131)和第二光收发单元(132)将光发射到触摸区域上。 第一光收发单元和第二光收发单元检测由镜部反射的光和复古反射部。 角度提取单元(14)计算关于第一和第二光收发单元中的至少一个没有接收到反射光的位置的发光角度。 坐标生成单元(15)计算光路彼此交叉的位置的坐标。 光线对应于发光角度。
