The invention relates to an electronic touch sensitive screen device 100 which may be an integral part of electronic data handling equipment which may be portable as by being hand held for example. The device 100 comprises a circuit including two electronic paths or leads 1 and 2, adapted to be connected with a source 3 for providing a pulse train of identical desired form (in the embodiment a square wave pulse train), an electronic comparator device 4 such as in the embodiment a D-type Flip-Flop connected with the two paths 1 and 2 and adapted to receive input signals 5 and 6 respectively from the path 1 and 2 and to provide an output 7 commensurate therewith, and a touch contact 8 of the ohmic kind along one of the paths 1. The path 1 is earthed or grounded at 9.
