technical field

The invention relates to a lamp tube clamping and electrical connection device and a lamp tube loading and unloading method, in particular to a lamp tube clamping and electrical connection that can quickly replace the lamp tube and does not require the steps of welding and unsoldering the lamp tube Device and lamp tube loading and unloading method.

Background technique

With the rapid progress of liquid crystal display (liquid crystal display, LCD) production technology, and its advantages of thinness, lightness, power saving and radiation-free, liquid crystal displays are widely used in personal digital assistants (PDAs) ), notebook computers, digital cameras, digital video recorders, mobile phones, computer screens and LCD TVs and other electronic products. Coupled with the industry's active investment in research and development and the adoption of large-scale production equipment, the quality of liquid crystal displays has been continuously improved, and the price has been continuously reduced, thus rapidly expanding the application field of liquid crystal displays. However, since the liquid crystal display panel in the liquid crystal display is a non-self-illuminating display panel, it needs the light provided by the backlight module to produce the display function.

A traditional liquid crystal display at least includes a liquid crystal display panel and a backlight module. The traditional backlight module includes a backplane, a reflector, at least one lamp tube, a diffusion plate and an optical film group. The optical film group includes, for example, a rhombus sheet and Diffusers, etc. The reflective sheet is flatly attached to the backboard, and the lamp tube is arranged on the reflective sheet. The diffusion plate is arranged on the lamp tube, the optical film group is arranged on the diffusion plate, and the liquid crystal display panel is arranged on the optical film group. In addition, the electrode end of the lamp tube is welded and electrically connected to one end of the wire through the soldering step, and the other end of the wire is electrically connected to a lamp inverter. The lamp voltage regulator will receive a power source to drive the lamp tube, so that the lamp tube emits light. In addition, the light emitted by the lamp will directly strike the liquid crystal display panel after passing through the reflection sheet, the diffuser plate and the optical film group.

However, when the lamp tube is damaged and the lamp tube needs to be replaced, because the electrode end of the lamp tube is welded to the wire, at first, the old lamp tube and the wire must be separated through a desoldering step. Then, after the new lamp tube is placed on the back plate, the new lamp tube and wires must be connected through soldering steps. As a result, the entire lamp tube loading and unloading process is quite complicated and time-consuming. For large-size LCD TVs, an LCD TV usually has dozens of lamp tubes. If more new and old lamp tubes are to be replaced according to the above-mentioned traditional lamp tube loading and unloading process, the entire lamp tube loading and unloading process will be more complicated. And the loading and unloading work hours of the whole lamp tube will be more tedious, which is quite uneconomical.
