Problems solved by technology

[0005] However, the cold cathode lamp 10 in the backlight module 1 will be gradually consumed due to the bombardment of ions and electrons due to the sealed metal electrode 103, thereby affecting the life of the cold cathode lamp 10, and the deterioration of the metal electrode 103 is currently used for The demand for high brightness of the cold-cathode lamp 10 becomes more significant. Therefore, the technology of external electrode cold-cathode lamps with different structures is being actively developed to avoid the loss of the internal metal electrode 103, and it is expected to effectively prolong the life of the cold-cathode lamp 10.

Abstract

Module of cold cathode lamp includes a basal plate, at least a pair of electrode, and at least a cold cathode lamp. The pair of electrode includes a first electrode, and a second electrode interleaved each other setup on the basal plate. The cold cathode lamp is setup on the basal plate.

Description

technical field [0001] The present invention relates to a cold cathode lamp module, in particular to a cold cathode lamp module with an external electrode structure. Background technique [0002] A backlight module is a key component widely used in flat panel displays, especially in liquid crystal displays. The backlight module is generally installed on the back of the display panel of the liquid crystal display, and according to the different functional requirements of the liquid crystal display, the backlight module can be mainly divided into two types: the direct type backlight module and the edge type backlight module. The light utilization rate of the module is better than that of the edge-lit backlight module, so it is mostly used in liquid crystal display panels with higher brightness requirements or larger sizes, such as LCD TVs. [0003] Currently, a cold cathode fluorescent lamp (CCFL) is generally used as the light source of the backlight module, please refer to ...
