  • Visible sensing transistor, display panel and manufacturing method thereof
    Patent number: 8735893
    Abstract: A display device includes an infrared sensing transistor and a visible sensing transistor. The visible sensing transistor includes a semiconductor on a substrate; an ohmic contact on the semiconductor; an etch stopping layer on the ohmic contact; a source electrode and a drain electrode on the etch stopping layer; a passivation layer on the source electrode and the drain electrode; and a gate electrode on the passivation layer. The etch stopping layer may be composed of the same material as the source electrode and the drain electrode. The infrared sensing transistor is similar to the visible sensing transistor except the etch stopping layer is absent.
    Type: Grant
