    • A plasma display device that enables a reduction of costs in implementing a touch panel function using infrared rays generated when displaying an image, which are emitted in a substantially uniform dispersion from a display area. One embodiment includes a plasma display panel (PDP) for displaying the image and a pair of infrared sensor cameras at two corners of the PDP. The infrared sensor cameras are either on the front or rear side of the PDP, and are utilized to detect changes in the amount of infrared rays emitted from the PDP. A controller determines a position where the amount of infrared rays is changed, which corresponds to a touch position, and transmits a detection signal indicating the location of the change in the amount of infrared rays. The infrared sensor camera has a lens with a view angle in the range of 90° to 180°.
    • 一种等离子体显示装置,其能够在使用从显示区域以基本均匀的色散发出的显示图像时产生的红外线降低实现触摸面板功能的成本。 一个实施例包括用于在PDP的两个角部显示图像的等离子体显示面板(PDP)和一对红外传感器相机。 红外传感器摄像机位于PDP的前侧或后侧,用于检测从PDP发射的红外线的量的变化。 控制器确定对应于触摸位置的红外线量改变的位置,并发送指示红外线量变化位置的检测信号。 红外传感器相机具有视角在90°至180°范围内的透镜。
