Description

technical field [0001] The invention relates to a backlight panel module, in particular to a backlight module with easy assembly and disassembly of lamp tubes. Background technique [0002] With the gradual popularization of liquid crystal panels, more and more users are using liquid crystal panels, and at the same time, the price of liquid crystal panels is also getting lower and lower. Generally speaking, after a period of use, the lamp tube of the backlight module is easily damaged or burnt and needs to be replaced. However, in today's era of low panel prices and compressed profit margins, it is not easy to provide good service quality. For easily damaged parts such as backlight modules and lamp tubes, if consumers can disassemble them in a very simple way, they will surely It can save the time and money of both manufacturers and consumers, and achieve win-win benefits. Therefore, the present invention is to provide a backlight panel module that is convenient for users ...
