Abstract

The present invention relates to a backlight module. It includes a backplate, a positioning structure and a component to be positioned. Said backplate possesses back surface and front surface, and a positioning hole which is passed through said front surface and back surface. Said positioning structure possesses a first positioning portion, said first positioning portion is passed through said positioning hole from front surface and projected from said back surface. Said component to be positioned can be positioned on said back surface by means of first positioning portion.

Description

technical field [0001] The present invention relates to a backlight module and a display device using the same, and in particular to a backlight module with a multi-reset structure and a display device using the same. Background technique [0002] With the progress of the flat-panel display industry, although the cost of the flat-panel display is reduced, the profit of the product is also reduced as the production technology matures and leads to mass production. Therefore, we must strive to simplify the design of each part of the product, and omit components while maintaining the proper functions to reduce costs. [0003] Traditionally, a backlight module in a liquid crystal display has many components, such as a lamp tube, a diffuser, a circuit board, an inverter, a cover, and the like. These components must be correctly positioned and fixed on the backlight module, so an appropriate positioning structure must be designed to position and fix each component. Usually, diffe...
