<p>A liquid crystal module, at least comprising a light source (1) and a light guiding device (3). The light guiding device (3) is fixed at a light-emitting side of the light source (1) and keeps a certain distance therefrom. The liquid crystal module also comprises a light-coupling device (9). The light-coupling device (9) is mounted between the light source (1) and the light guiding device (3), for controlling a light-coupling distance between the light source (1) and the light guiding device (3). As the light-coupling device (9) is mounted between the light source (1) and the light guiding device (3), the liquid crystal module can keep a light-coupling distance between a light guiding plate and the light source (1) at a designed value, which can avoid change in the light-coupling distance caused by differences in and thermal expansion of the light guiding plate or an LED product, further increasing the light-coupling efficiency of the liquid crystal module, and improving the quality of the product.</p> |
