<p>Provided are a touch display device and a touch location detection method. The touch display device provided in the embodiments of the present invention comprises a display, a light guide assembly and a detection unit, wherein the light guide assembly is arranged opposite to the surfaces of the display, other than an out-light surface, and is used for guiding light rays reflected by the surface of a touched object and light rays emitted from the out-light surface of the display at that moment into the detection unit when the touched object comes into contact with the out-light surface of the display. The detection unit is arranged opposite to a bottom surface of the display and is used for generating a touch image which contains the touch location of the touched object on the out-light surface of the display in accordance with the obtained light rays. The embodiments of the present invention solve the problems of the distortion of image colours and image blurring which exist when an existing capacitive touch display device is used.</p> |
