Problems solved by technology
[0004] However, the above structure will encounter a great difficulty in the manufacture of thin light guide plates
In terms of injection molding, the thickness of the current injection technology is limited to 0.3mm, and the size of the thickness less than 0.3mm cannot be molded
In addition, if rolling or extrusion is used, it is obviously impossible to achieve a finished product with a relatively thin flat plate on one side and a wedge-shaped structure on the other.

Embodiment Construction
[0039] The invention relates to a backlight module and a light source structure thereof with a thin optical plate and capable of improving the utilization rate of light energy. In a preferred embodiment, the light-emitting element of the light source structure is a light-emitting diode. In particular, the light-emitting diodes are preferably arranged in a light-incident manner inclined at an angle to the surface of the optical plate. In other words, the light-emitting diodes are preferably arranged adjacent to the optical plate and the lens body, respectively. In addition, the additional lens is preferably arranged between the optical plate and the light-emitting element by coating. However, in other different embodiments, the lens body can also be manufactured by computer numerical control (CNC) or other methods. The specific embodiments and steps of the present invention will be further described below in conjunction with the accompanying drawings:
[0040] As shown in FIGS. 2 a...

Abstract
The invention discloses an aphototropism mode and its light source structure, which comprises the following parts: optical board piece, luminous element and lens, wherein the luminous element is set on the surface of optical board piece, which has a light ejection direction; the light ejection direction and the surface of optical board piece display a separation angle at thita; the luminous element also contains luminous body and packing material to cover the luminous body; the lens is set on the surface to connect the optical board piece and luminous element, which has a slope with one end connecting the luminous element and the other end connecting the optical board piece; the luminous body adjoins the optical board piece and lens. The invention overcomes the defect of present technique, which using luminous diode to lighten the conductive structure and thin the aphototropism mode and its light source structure.
Description
Technical field [0001] The present invention relates to a backlight module and its light source structure, and more particularly to a backlight module and its light source structure using light emitting diodes (LED, Light Emitting Diode) to make light guide plate structures lighter and thinner. Background technique [0002] Since the light guide plate occupies a large proportion of the thickness and weight of the entire backlight module, facing the current demand for thinner and lighter panel market, the thinning of the light guide plate is an inevitable trend. However, with the current technology, the backlight module that uses LEDs as the light source cannot keep up with the speed of the thinning of the light guide plate, that is, the thickness of the current light guide plate can be as thin as 0.3mm, and the thinnest light emitting device has been developed. The thickness of the diode is 0.4mm. Particularly, when the thin light guide plate adopts the side light input mode, the...
