Zusammenfassung: | The invention discloses a capacitive touch electroluminescence display screen which combines an electroluminescence display panel and a capacitive touch panel; wherein, the electroluminescence display panel is electrically connected with a driving circuit to receive voltage generated by the driving circuit; the periodic waveform of the voltage comprises a relatively high voltage zone and a relatively low voltage zone, and the relatively high voltage zone drives the electroluminescence display panel for luminescence; the capacitive touch panel is positioned on the surface of the electroluminescence display panel and is electrically connected with a controller; when the electroluminescence display panel is positioned in the relatively low voltage zone, the controller measures the capacity change of the capacitive touch panel. The capacitive touch electroluminescence display screen utilizes time difference to avoid electric field interference to the capacitive touch panel by the relatively high voltage zone. |
