Abstract
A touch-sensitive apparatus comprising a panel defining a touch surface; a first set of opposite and essentially parallel rows of components, and a second set of opposite and essentially parallel rows of components. The second set of opposite and parallel rows being essentially orthogonal to the first set of opposite and parallel rows. The components include emitters and detectors, each emitter being operable for propagating an energy beam across the touch surface inside the panel, and each detector being operable for detecting transmitted energy from at least one emitter. Two of the rows of the first and second set are interleaved rows each having an interleaved distribution of emitters and detectors, and the further two rows of the first and second set are base rows each having a distribution of components comprising at least 70% emitters or detectors.
