<p>A touch-sensitive apparatus is configured to define a touch surface on a panel by propagating diverging energy beams across the touch surface inside the panel. Two rows (20A, 20B) of components (2, 3) 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 (20A, 20B) are defined by consecutive component blocks (B) that each contain only components (2, 3) of one type and are defined by type and number of included components. Each row (20A, 20B) is defined to have consecutive component blocks (B) of alternating type. To achieve an improved spatial resolution of the touch-sensitive apparatus for a given number of components, at least one of the rows (20A, 20B) is designed to include at least three different component blocks (B) which differ with respect to at least one of number and type.</p> |
