Abstract
An organic light-emitting device (OLED) display is provided. The OLED display includes a thin-film transistor (TFT) substrate having a plurality of TFTs and a plurality of data lines that control the plurality of TFTs. The OLED display also includes a conductive shielding layer disposed over the TFT substrate and an OLED layer disposed over the conductive shielding layer. The OLED layer includes a plurality of OLEDs that are driven by the plurality of TFTs. The OLED layer also includes a touch panel layer disposed over the OLED layer. The conductive shielding layer is configured to reduce noise coupling between the TFT substrate and the touch panel layer.
