Problems solved by technology

[0004] Generally speaking, in order to improve the brightness of the liquid crystal display, the metal lamp frame used to support the cold cathode fluorescent lamp in the backlight assembly is usually designed to have high reflectivity, but the result of using the metal lamp frame of this material is that it causes a high reflectivity in the cold. An equivalent capacitance is generated between the cathode fluorescent lamp and the metal lamp holder
When the cold-cathode fluorescent lamp is knocked, if its grounding design is poor, it will not be able to lead out too much current in the cold-cathode fluorescent lamp, and it will be in an unstable state, resulting in flickering of the cold-cathode fluorescent lamp, which will cause the liquid crystal display. Displayed image quality is unstable

Embodiment Construction

[0032] As shown in FIG. 1 and FIG. 2 , the CCFL tube assembly according to the present invention includes: a metal lamp frame 10 , a conductive member 20 and a CCFL tube 30 .

[0033] The metal lamp holder 10 has high reflectivity, and the metal lamp holder 10 has an accommodating space 11 , and the accommodating space 11 has an emitting end 12 (see FIG. 3 ).

[0034] The conductive member 20 is arranged in the accommodating space 11 and contacts the metal lamp holder 10. Of course, the shape of the conductive member 20 can be designed as a ring, and it can be sleeved on the cold cathode fluorescent lamp 30, or its shape can be designed as shown in FIG. 3 As shown, the conductive member 20 has a notch 21 for receiving the CCFL 30 . Of course, the conductive member 20 can be made of transparent rubber to avoid blocking the light from traveling.

[0035] The cold cathode fluorescent lamp 30 is filled with mercury molecules and gas, and is arranged in the accommodation space 11,...

Abstract

A cold cathode fluorescent lamp assembly contains metal lamp stand, conductive piece and cold cathode fluorescent lamp which are in metal lamp stand, the conductive piece contacted with metal lamp stand and cold cathode fluorescent lamp which is coated with conductive layer on outer surface, in lighting process the overcurrent is led to metal lamp stand by conductive piece and conductive layer, then led to outer side by metal lamp stand.

Description

technical field [0001] The invention relates to a cold cathode fluorescent lamp assembly, which is applied to a liquid crystal display, in particular to a non-flickering cold cathode fluorescent lamp assembly, which stabilizes the picture quality displayed by the liquid crystal display. Background technique [0002] Liquid crystal display can be roughly divided into three types: transmissive liquid crystal display, reflective liquid crystal display and transflective liquid crystal display. The transmissive liquid crystal display is provided with a backlight module (Backlight Module) to provide a light source. [0003] The backlight assembly is mainly composed of a light source, a Light Guide Panel (LGP) for guiding the direction of light, a diffuser (Diffuser), and a plastic frame (Frame). The light sources used in backlight components can be roughly divided into cold cathode fluorescent lamps (Cold Cathode Fluorescent Lamp; CCFL), hot cathode fluorescent lamps, light-emitti...
