Abstract

The invention discloses a backlight module, which comprises a plurality of lamp tubes, a first circuit board and a second circuit board. Each lamp has a first electrode and a second electrode. The first circuit board has a plurality of first openings and first conductive clips, wherein the first electrode passes through the first holes and is clamped by the first conductive clips. In addition, a plurality of lamp current adjustment elements are arranged on the first circuit board, and the current adjustment elements are electrically connected to the first electrode through the first conductive clip. In the above-mentioned backlight module, using the first conductive clip or the clamping pin of the current adjustment element to fix the electrode of the lamp tube helps to speed up the assembly process of the backlight module.

Description

technical field

[0001] The present invention relates to a backlight module, and in particular to a backlight module which utilizes a conductive clip or a clamp pin of a current adjustment element to fix lamp tube electrodes. Background technique

[0002] Liquid Crystal Displays (LCDs) are widely used in daily life, and more and more attention has been paid to the stability of the optical performance and the lightness and thinness of the appearance design of the LCDs. Liquid crystal displays usually use cold cathode fluorescent lamps (Cold Cathode Fluorescent Lamp, CCFL) as the backlight source. When the size of the liquid crystal display becomes larger, the number of lamp tubes used will also increase. Therefore, multiple lamp tubes are connected in parallel (for example, mutually Arranged in parallel) the technology used came into being.

[0003] However, since the difference of each lamp tube cannot be ignored, and the leakage current of each lamp tube is also different d...
