This disclosure relates to a touch display panel and more specifically to a borderless touch display panel. The touch display panel includes a Fresnel lens, a touch-sensing panel and a coordinate transforming module, wherein the flat display panel and the Fresnel lens are spaced apart by a distance. The flat display panel outputs an original image having an original coordinate system. The Fresnel lens is used to transform the original image into a display image to be viewed by the user, wherein the display image has a display coordinate system. The touch sensing panel will sense the user's touch and output a touch coordinate of a touch and the coordinate transforming module will transform the touch coordinate into an action coordinate based on a transformation parameter set. The transformation parameter set includes a magnification parameter and a shift parameter for compensating for the positional difference between the touch coordinate and the action coordinate due to the distance between the flat display panel and the Fresnel lens.
