  • Patent number: 7586253
    Abstract: An enhanced plane light source has a luminescent layer independently disposed in each recess formed on a light-transmittable substrate, so that field emission electrons directly impact the luminescent layer to produce light, which is not shielded by the cathode. The enhanced plane light source also includes a substrate forming a bottom structure thereof. The bottom substrate has a metal reflection surface to increase the reflectivity and upgrade light-emitting efficiency and luminous intensity. The recesses on the light-transmittable substrate have an approximate semi-circular or semi-parabolic cross section to increase the high field region at the cathode and the effective luminescent area at the anode, so that the luminous intensity and evenness are also largely increased.

  • Publication number: 20090167144
    Abstract: A surface light source apparatus with dual-side emitting light includes a transparent cathode structure, a transparent anode structure, a fluorescent layer and a low-pressure gas layer. The transparent cathode structure and the transparent anode structure are opposite to each other and respectively a surface structure. The fluorescent layer is located between the transparent cathode structure and the transparent anode structure. The low-pressure gas layer fills a space between the transparent cathode structure and the transparent anode structure and functions to induce the cathode for evenly emitting electrons. In addition, the electron mean free path of the low-pressure gas layer allows at least sufficient electrons to directly impact the fluorescent layer under an operation voltage.

  • Publication number: 20070132363
    Abstract: A light source for projection system is installed on a projector and employs the field emission property between a cathode and an anode to stimulate a fluorescent powder layer for the same to emit light. The projection light source has sufficient brightness without the problems of producing high amount of heat and short service life. The high brightness of the light source enhances the quality of images projected by the projector and largely increases the economic effects of the projector.

  • Publication number: 20070114913
    Abstract: A field emission backlight module has a field emission structure with cathode and anode provided on the same plane, so that electrons directly penetrate an independently provided fluorescent powder layer to produce light. The light is emitted uniformly without the need of the conventional optical membrane. Since the light produced by the fluorescent powder layer is not blocked by the anode, the problem of charge accumulation on the fluorescent powder layer is avoided, and it is not necessary to use expensive light-transmittable conducting glass as the anode. With the cathode and the anode located at the same plane, it is not necessary to use a precision spacer to adjust the distance between the cathode and the anode, enabling the module to be manufactured at reduced cost and high good yield. When the color sequential displaying method is adopted, expensive color filters required in the conventional LCD may be omitted.
