DISPLAY DEVICE

摘要

The invention relates to a display device having under-gate emitters, i.e. emitters where the gates (203) are arranged under the cathodes (205), beneath an insulating layer (204). In order to protect the emitters from a high electric field from an anode (A), an electron guidance element (207) is placed between the emitters and the anode. This allows a relatively low voltage swing to be used for controlling the electron emission from the emitters from the on-state to the off-state.
