  • Field emission display and driving device thereof
    Patent number: 7122967
    Abstract: A field emission display with a first substrate and a second substrate which are arranged opposite to each other and have a specific distance between them. At least one first electrode is formed on the first substrate and at least one second electrode is formed on the second substrate. At least one third electrode is insulated from the first electrode and an electron emission source is connected to the third electrode. A fourth electrode controls the electrons emitted from the electron emission source so that they reach the second electrode. A driver detects a current flowing through the fourth electrode and controls a driving voltage applied to the fourth electrode based on the detected current.
    Type: Grant
