Abstract
In a flat panel display, two direction sensing electrodes, respectively representing an X-axis sensor and a Y-axis sensor, are disposed on both sides of a substrate of a color filter of the flat panel display. One direction sensing electrode is disposed in the black matrix on one side of the substrate and the other direction sensing electrode is disposed on the other side of the substrate locating farther from the black matrix. The configuration provides a much thinner dimension for the flat panel display with touch function while the touch function is less interfered by the display panel.
