Thermal electron emitting backlight unit |
摘要 |
A thermal electron emission backlight unit includes: first and second substrates arranged parallel to each other; first and second anode electrodes respectively arranged on inner surfaces between the first and second substrates; wall frames adapted to seal an inner space between the first and second substrates; a movable spacer holder and a fixed spacer holder arranged inside the wall frames to face each other; a plurality of spacers arranged between the first and second substrates and adapted to maintain a gap therebetween, wherein ends of the spacers are coupled to the movable and fixed spacer holders; a plurality of cathode electrodes arranged across the spacers between the first and second substrates; and a phosphor layer arranged on the second anode electrode. The spacers include tension spacers adapted to provide tension between the movable and fixed spacer holders by pushing the movable spacer holder away from the fixed spacer holder. The first substrate is adapted to pass white light therethrough.
