TOUCH DISPLAY DEVICE

摘要

The touch display device includes a cover plate, a touch sensor unit, a display unit and a pressure sensor unit. The touch sensor unit is configured to sense a touch signal applied to the cover plate, the display unit includes a liquid crystal function layer and a backlight module. The pressure sensor unit includes an upper conductive electrode layer and a lower conductive electrode layer, which cooperative forming a capacitance sensor to sense a pressure signal applied to the cover plate. The upper conductive electrode layer is positioned between the liquid crystal function layer and the backlight module. The lower conductive electrode layer is positioned beneath a side of a reflector of the backlight module away from the light guide plate.
