We demonstrated a metal-mesh electrode based touch screen panel that does not have back surface touch error (BTE) due to panel bending. It was fabricated with a 7-inch double layer structure using the roll-to-roll process. Samples with various mesh pitch ratios for the sensing (Rx) and driving (Tx) electrodes were prepared and tested. BTE removal was ensured at touch pressures below 650 gf with mesh pitch ratios of less than 0.25 for the Tx/Rx electrodes. The linewidth of the fabricated electrode was 3 µm, and the transmittance was 87.51% at 550 nm. At this time, the mesh pitch of the Tx was set to 220 µm, and the Rx was 880 µm.
