Title:
FLUORESCENT LAMP AND IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/043088
Kind Code:
A1
Abstract:
In order to obtain effective luminance and light-emission efficiency while avoiding electric discharge, it is required to sufficiently increase the current luminance efficiency of gas and the electron use efficiency of an electron source. In a fluorescent lamp, an anode electric field is increased by setting the pressure of a filled rare gas or molecular gas to 10 kPa or more, the anode voltage to 240 V or less, and the substrate interval to 0.4 mm or less. Further, the effect of the current luminance efficiency correspondingly increasing in proportion to the electric field is used. Also, by using an MIM electron source having an electron use efficiency exceeding 10% as the electron source, a zero-discharge fluorescent lamp having a light emission luminance of 104 [cd/m2] or more and a light emission efficiency of 120 lm/W or more is implemented.
