Abstract:
This invention provides a method for maintaining vacuum of a panel module and a structure of the panel module. A sealing material is suspended inside the panel module right above an exhaust opening of the panel module connecting with an exhaust tube. After exhausting the inside of the panel module, the sealing material is heated and molten so as to drop down to seal the exhaust tube. As such, the panel module becomes vacuum-tight. During a subsequent annealing process to heat the exhaust tube to its melting temperature, ambient air is prohibited from flowing into the panel module.
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.
