Abstract: A touch display (100) is disclosed. In the invention, a touch connection (271) is provided between the touch measurement node (205) and the segment display electrode (107), arranged to provide a touch measurement signal (205s) for touch detection to the segment display electrode (107). The touch connection (271) comprises an isolator (272) arranged to isolate the segment driving signal (215s) of the segment display electrode (107) from the touch measurement unit (200). The touch display (100) also comprises a shield connection (187) between the shield signal node (206) of the touch measurement unit (200) and the driving electronics ground node (110) of the driving electronics unit (210) arranged to connect the shielding voltage signal (206s) to the driving electronics ground node (110).

Abstract: A method for driving an electroluminescent touch display (10) is disclosed. The electroluminescent touch display comprises a thin film element (100a) with one or more segment electrodes (107), one or more common electrodes (106), and two or more touch electrodes (101, 101a, 101b). The method comprises a light excitation step (300, 300a, 300b), a touch indication step (320, 320a, 320b), the touch indication step (320, 320a, 320b) comprising detecting if any of the touch electrodes (101, 101a, 101b) is touched, and a touch determination step (310, 310a, 310b), the touch determination step (310, 310a, 310b) comprising determining which of the touch electrodes (101, 101a, 101b) is touched. If none of the touch electrodes (101, 101a, 101b) is touched, the touch determination step (310, 310a, 310b) is left unexecuted. An electroluminescent touch display (10) is also disclosed.

Abstract: A touch display (100) is disclosed. It comprises a transparent thin film display element (100a) comprising a first and a second patterned conductor layer (100b, 100c) with common and segment display electrodes (106, 107) and touch electrodes (101). The touch display also comprises a driving electronics unit (210) comprising driving circuit nodes (110, 215, 216), and a touch measurement unit (200). The touch display (100) comprises an electric connection (251) between the shield signal node (206) of the touch measurement unit (200) and a driving circuit node (110, 215, 216) of the driving electronics unit (210) arranged to couple the shielding voltage signal (206s) to the driving circuit node (110, 215, 216).
