Abstract:
An electronic display panel comprising a plastic substrate; a bottom shield metal (BSM) on the plastic substrate; a thin-film transistor (TFT) on the BSM, the TFT and the BSM at least partially overlapping each other; and an active buffer layer between the TFT and the BSM, wherein the BSM is connected to one of a gate electrode, a source electrode, and a drain electrode of the TFT. A bottom shield metal (BSM) on the plastic substrate, the BSM located to minimize formation of a back channel in a pixel circuit by trapped charges of the plastic substrate, the pixel circuit in a pixel area defined by a gate line and a data line on the plastic substrate, the pixel circuit on the active buffer layer including a plurality of TFTs and a plurality of component interconnecting nodes.
