Abstract

In a touch panel and display panel structure or an integrated touch display panel structure, an antenna pattern is disposed on a touch module, a display module or an integrated touch display module for an increased distance between the antenna pattern and electronic components below the structure, reducing electromagnetic effect caused by the electronic components and improving the antenna performance. The antenna pattern is arranged at two opposite edges of a top surface of the touch and display module or the integrated touch display module, and also at side surfaces of a housing non-coplanar to the top surface such that the antenna pattern is located outside the displaying area of the display module. Maintaining the effective antenna area and enhancing the working bandwidth of the antenna, the side width of surface of the touch panel and display panel structure or the integrated touch display panel structure is significantly reduced.
