Embodiment Construction

[0052] see Figure 1(a) and 1(b) , which is a schematic diagram of the first embodiment of the present invention. The backlight module 100 of the liquid crystal display has a light emitting unit 110, a light guide plate 120, a back plate 130 and an air gap layer 140, wherein the light guide plate 120 has a plurality of microstructures 121, a light incident surface 122, a light output surface 123 and a bottom surface 124, and the back plate 130 has a back plate main body 131 , a reflective material 132 and a peripheral frame 133 .

[0053] The light emitting unit 110 is configured to provide light to the light guide plate 120, and the light emitted by the light emitting unit 110 reaches the liquid crystal display panel (not shown) through the reflective material 132 of the light guide plate 120 and the back plate 130, thereby providing a surface light source. to the LCD display. The light emitting unit 110 may be a light emitting diode (light-emitting diode, LED), a cold cath...

Abstract

The invention provides a backlight module of a liquid crystal display. The backlight module includes a light guiding plate and a back plate. The light guiding plate has a bottom surface and a plurality of micro-structures formed on the bottom surface, and the back plate has a main body and a reflecting material, wherein the main body has an inner surface being a flat plane and an outer surface, the reflecting material is formed on the inner surface and the inner surface of the back plate is configured opposite the bottom surface of the light guiding plate. The invention further provides a manufacturing method of the backlight module of a liquid crystal display. The manufacturing method includes: providing a back plate having a plate main body with an inner surface being a flat plane and anouter surface; forming a reflecting material on the inner surface; providing a light guiding plate having a first surface, a second surface and micro-structures; and configuring the light guiding plate and the back plate to make the inner surface opposite to the second surface.

Description

technical field [0001] The invention relates to a backlight module of a liquid crystal display and a manufacturing method thereof, in particular to a backlight module including a backplane main body with reflective material and a manufacturing method thereof. Background technique [0002] Commonly used liquid crystal display backlight modules mainly include a light source, a light guide plate, optical glue, a reflector and a back plate, wherein the reflector is bonded to the light guide plate by means of optical glue. In order to allow most of the light emitted from the light source to reach the LCD panel, there will be multiple dot microstructures formed on one side of the light guide plate, and the side of the light guide plate with dot microstructures will be bonded through optical glue and reflective sheet , the pattern design on the dot microstructure can destroy the total reflection in the light guide plate. The light emitted by the light source will enter the light g...
