光学触摸输入系统和在该系统中建立参考的方法
摘要：
本发明提供一种光学触摸输入系统和在该系统中建立参考的方法，该方法包括以下步骤：由位于显示面板的第一角部、第二角部和第三角部处的相应发射器发出光，并由位于所述显示面板的第四角部处的检测器接收直射光；所述位于第四角部处的检测器对位于第一角部、第二角部和第三角部处的相应发射器的直射光所产生的相应的第一脉冲信号、第二脉冲信号和第三脉冲信号进行检测；相应的第一脉冲信号、第二脉冲信号和第三脉冲信号对应于位于第四角部处的检测器的像素位置；以及将相应的第一脉冲信号、第二脉冲信号和第三脉冲信号的相应的像素位置与所述显示面板的相应的预定第一参考角度、预定第二参考角度和预定第三参考角度相关联。
摘要（英）：

A method of establishing an optical touch input system and a reference in the same, includes emitting light by emitters located at respective first, second, and third corners of the display panel, and receiving direct light by a detector located at a fourth corner of the display panel, the detector at the fourth corner detecting respective first, second, and third impulse signals generated by the direct light of the emitters located at the respective first, second, and third corners, the respective first, second, and third impulse signals corresponding to pixel positions of the detectors located at the fourth corner and correlating the respective pixel positions of the respective first, second, and third impulse signals with respective predetermined first, second, and third reference angles of the display panel.
