Abstract
The present invention discloses a touch control device, which is addressed to the rimple problem resulting from the full-lamination design of the touch control panel and the liquid crystal display module. The present invention compensates for the elevation drop of the slightly lower control circuit region of the liquid crystal display module in a thickness-increasing way to make the entire liquid crystal display module have an identical elevation. In some embodiments, the present invention increases the thickness of a portion of a ground tape or an optical adhesion layer to compensate for the elevation drop of the liquid crystal display module with respect to the touch control panel. Thereby, the rimple problem is effectively solved.
