Abstract

The invention relates to a light conducting device and phototropism module of light conducting device, which consists of light conducting plate and integral-form template frame, wherein the light conducting plate contains a light-in face, a light-out face adjacent to the light-in face and multiple openings in the combination part of light conductivity plate and template frame with an arc corner in each opening.

Description

【Technical field】 [0001] The invention relates to a light guide device and a backlight module, in particular to a light guide device and a backlight module with uniform light output. 【Background technique】 [0002] Backlight modules are widely used in display devices, such as liquid crystal displays, mobile phones, etc., but many display devices are non-self-luminous displays, which are mainly realized by controlling the passage or non-passage of light emitted by external light sources, so corresponding backlight or front light modules are required. The backlight or front light module can guide the light emitted by the external light source to the display panel to realize the display function. In addition, in order to save costs and reduce the number of parts, the integrated design of the light guide plate and mechanical components of the backlight module has been gradually adopted by designers. [0003] Please also refer to figure 1 and figure 2 , a prior art backlight ...
