  • Publication number: 20240118759
    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).

  • Publication number: 20240061526
    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.

  • Patent number: 11578944
    Abstract: A transparent thin film electroluminescent display device includes a first transparent thin film electroluminescent display having a substrate and a first active layer capable of emitting a spectrum of light in a wavelength of visible light. The transparent thin film electroluminescent display device further includes a second transparent thin film electroluminescent display having a substrate and a second active layer, the first and second transparent thin film electroluminescent displays being arranged in a superposed manner such that the first and second active layers are spaced apart from each other for forming the transparent thin film electroluminescent display device with a superposed structure.

  • Patent number: 11335766
    Abstract: A transparent thin film display element (100) with a display region(101), and a transition region (105) having a first edge (106) bordering the display region and a second edge (107) opposite to the first edge, the transparent display element having a layer stack (103) comprises:a first conductor layer (110); a second conductor layer (120); and an emissive layer (130) superposed between the first and the second conductor layers and configured to emit light upon electrical current flowing through the emissive layer between the first and the second conductor layers. At least one layer (120) of a group comprising the first and the second conductor layers and the emissive layer has, in the transition region (105), a first coverage at the first edge (106), a second coverage lower than the first coverage at the second edge (107), and an intermediate coverage lying between the first and the second coverage.
