Problems solved by technology
However, when the existing double-sided backlight module is used in a liquid crystal display module, there will be an obvious defect-the light will always pass through the two liquid crystal display panels of the liquid crystal display module, that is, it cannot emit light on one side.
When the user wants one of the LCD panels to display images while the other LCD panel does not display images, because the LEDs in the existing design cannot be turned off, half of the light will be wasted on the LCD that does not need to be displayed. panel, wasting energy

Embodiment Construction
[0018] The purpose of the embodiment of the present invention is that the light source can be moved on one side of the light incident surface of the two light guide plates to adjust the relative position of the light source and the light incident surface of the two light guide plates, so as to realize: when two liquid crystal display panels need to work When the light source is adjusted, it is located at the center of the two light guide plates, and the light emitted by the light source can be evenly incident on the two light guide plates to achieve double-sided lighting effects; when only one LCD panel is required to work, the light source is adjusted to be located at the center of one of the light guide plates. position, all the light emitted by the light source is incident on the light guide plate to achieve a single-sided luminous effect. At this time, the driving current of the light source can be lowered to achieve the purpose of saving energy consumption.

The invention discloses a double-faced backlight module and a liquid crystal display module. A light source and a sliding assembly are connected. The light source can slide along a preset direction, so that relative locations between the light source and light incident surfaces of two light guide boards can be adjusted. When two liquid crystal display panels need to work, the light source is adjusted to a center location between the two light guide boards. The light emitted by the light source can be imported into the two light guide boards uniformly, thereby realizing a double-faced light emitting effect. When only one liquid crystal display panel needs to work, the light source is adjusted to a location of one light guide board. The light emitted by the light source can be fully imported into the light guide board. At this time, the drive current of the light source can be reduced, thereby saving the energy.
Description
technical field [0001] The embodiments of the present invention relate to the field of liquid crystal display technology, and in particular to a double-sided backlight module and a liquid crystal display module having the double-sided backlight module. Background technique [0002] Existing double-sided backlight modules usually use one or a group of LEDs (Light Emitting Diode, light emitting diode) as the light source, and the light emitted by the light source is emitted from the front and back sides of the light guide plate through a light guide plate, thereby realizing double-sided backlight modules. glow effect. However, when the existing double-sided backlight module is used in a liquid crystal display module, there will be an obvious defect-the light will always pass through the two liquid crystal display panels of the liquid crystal display module, that is, it cannot emit light on one side. When the user wants one of the LCD panels to display images while the other L...
