A display apparatus includes a display having an array of pixels formed in rows and columns. The rows of pixels are separated by row inter-pixel gaps and the columns of pixels separated by column inter-pixel gaps. A touch-screen includes a transparent dielectric layer having a row side and an opposed column side located over the display, the touch screen having row electrodes spaced apart by row inter-electrode gaps located on the row side of the transparent dielectric layer and column electrodes spaced apart by column inter-electrode gaps located on the column side of the transparent dielectric layer. The row and column electrodes are separated by the transparent dielectric layer. Ground lines are located on the row side between neighboring row electrodes in the row inter-electrode gaps and between the pixels in a row inter-pixel gap.
