Abstract
The present disclosure provides a touch display having a force touch function. The touch display includes a backlight module, a liquid display panel and a force touch sensing circuit. The backlight module is configured to output light and includes a metal layer and a sensing layer. The liquid display panel includes a plurality of data lines and a plurality of gate lines. The force touch sensing circuit is electrically connected to a plurality of first sensing lines to sense a force of the touch of the user through the sensing layer, in which the first sensing lines are the data lines or the gate lines. In some cases, the sensing layer can be omitted, and the metal layer is used to replace the sensing layer.
