Abstract
A display device uses electron accelerating layers in conjunction with electrodes at different voltages to emit electron beams with energy levels sufficient to excite a gas, which emits ultraviolet rays that in turn excite a light emitting layer to emit visible light. The use of electron accelerating layers makes it possible to excite the gas using a lower driving voltage and achieve improved luminous efficiency.
Claims34
A display device, comprising:
- a first substrate and a second substrate opposing each other and having a space between them;
- a cell positioned between the first substrate and the second substrate;
- a first electrode positioned to correspond to the cell;
- a second electrode positioned to correspond to the cell;
- a first electron accelerating layer positioned on the first electrode and being capable of emitting a first electron beam into the cell;
- a gas inside the cell and being capable of generating ultraviolet rays when excited by the first electron beam;
- and
- a light emitting layer positioned inside the cell and being capable of generating visible light when excited by the ultraviolet rays.
