Abstract
A touch-sensitive apparatus is configured to define a touch surface on a panel by propagating diverging energy beams (e.g. of radiation) across the touch surface inside the panel. Two rows (A,B) of components () of a first type that emits energy as a diverging beam and a second type that detects energy are functionally connected to the panel at opposite ends of the touch surface. The rows (A,B) are defined by consecutive component blocks (B) that each contain only components () of one type and are defined by type and number of included components. Each row (A,B) comprises a respective sequence (S) of two component blocks (B) of different types and is defined by systematically repeating the sequence (S) along the respective opposite end. To achieve an improved spatial resolution of the touch-sensitive apparatus for a given number of components, at least one of the sequences (S) is selected to consist of two component blocks (B) with different number of components, and the sequences (S) are selected such that at least one component block (B) differs between the sequences (S).
