Abstract
A method for making a heatsink device to be incorporated into a backlight module of a liquid crystal display device is provided and the method comprises the steps of: a) providing a hollowed tube having a substantially rectangular cross section, and the tube including a first support portion, a second supporting, a first vertical section, and a second vertical section interlinked with each other; and b) cutting the hollowed tube along the first and second vertical sections along a longitudinal direction such that first heatsink unit configured with the first supporting portion and the first vertical section, and a second heatsink unit configured with the second supporting portion and the second vertical section are created. The disclosure of the present invention can readily reduce material cost, while promotes the design of light, slim and compact of the product.
