Embodiment Construction

[0013] see figure 2 , is a three-dimensional schematic view of the backlight module of the present invention. The backlight module 2 of the present invention includes a light source 21 and a light guide plate 22. The light guide plate 22 is flat and includes a light incident surface 221 and a light exit surface 222 connected to the light incident surface 221. The light guide plate 22 For guiding and transmitting the light emitted by the light source 21, the light source is a light emitting diode.

[0014] The backlight module 2 includes a tube cover 23, which is located on the light incident surface 221 side of the light guide plate 22. The tube cover 23 is fixed on a rotating shaft support 30, and the rotating shaft support 30 can rotate and drive the tube. The cover 23 rotates. The tube cover 23 has a light outlet 231, the light source 21 is arranged in the tube cover 23 relative to the light outlet 231, the circuit driving device 211 of the light source 21 is arranged on...

Abstract

A backlight module used in digital video product consists of a light source, a light guiding plate and a rotating barrel - type cover. It is featured as having a light incoming surface on light guiding plate, setting barrel - type cover at light incoming surface side of light guiding plate, having a light outgoing opening on barrel - type cover and setting light source opposite to said opening in barrel - type cover.

Description

【Technical field】 [0001] The invention relates to a backlight module, in particular to a backlight module used in digital video products. 【Background technique】 [0002] Since the liquid crystal in the panel of the liquid crystal display device does not emit light itself, in order to achieve the display effect, it is necessary to provide the panel of the liquid crystal display device with a light source device, such as a backlight module, whose function is to provide the panel of the liquid crystal display device with sufficient brightness and uniform distribution. Planar light enables it to display images normally, so it becomes one of the key components of liquid crystal display devices. [0003] With the continuous expansion of the application field of liquid crystal display devices, especially the application of digital imaging products, such as digital cameras for mobile phones, digital video cameras, etc., the requirements for the backlight module of liquid crystal dis...
