[0003] 然而,已知技术中的显示装置1,需于显示面板的后方设置红外线发光二极管以及光学传感器,才能感测使用者与显示装置I的距离,如此一来,必需增加材料成本的支出。 [0003] However, the display device 1 is known in the art, to be provided in rear of the display panel, an infrared light emitting diode and an optical sensor sensing the distance to the user and the display device I is, thus, necessary to increase the material cost expenditure . 而且,在制程上,还必须于保护玻璃对应红外线感测元件11的地方,增设红外线油墨,不仅耗费更多的材料成本,且须经过额外的制程及时间来达成此设计。 Further, in the manufacturing process, the cover glass must correspond to the place of the infrared sensing element 11, additional infrared ink, not only consume more material cost, and subject to an additional process time and to achieve this design.

[0004] 因此,如何提供一种触控显示系统、显示装置及其画面关闭方法,可减少材料成本,更可简化制程,以达到节省能源消耗,且避免于执行通话功能时误触触控面板。 [0004] Therefore, how to provide a touch display system, a display device and a method of closing a screen, you can reduce material costs, simplifies the process, in order to achieve energy consumption saving, and to avoid inadvertently calling the implementation of the touch panel .
