Backlight module and display device provided with backlight module

Abstract

The invention discloses a backlight module and a display device provided with the backlight module. The backlight module comprises a light guiding plate, a light source and a rubber frame, wherein thelight guiding plate is provided with at least one gap, the rubber frame accommodates the light guiding plate and the light source, the face, close to the light guiding plate and the light source, ofthe rubber frame is a rubber frame inner wall, a light incidence side is arranged at the rubber frame inner wall close to the light source, a light emergency side is arranged at the rubber frame innerwall close to the gaps, the rubber frame part from the unidirectional light incidence side of the rubber frame to the light emergency side of the rubber frame is the first part of the rubber frame, and the residual part of the rubber frame is the second part of the rubber frame. The first part of the rubber frame is made of a light-transmitting material, the outer surface of the first part of therubber frame is provided with a reflection layer, and the light incidence side of the rubber frame and the light emergency side of the rubber frame are light-transmittable. A backlight source is reused to serve as a compensative light source, and the inherent rubber frame serves as a light path, so that the space occupied by the device is decreased, the area of a display zone is increased, the border at each gap can be made narrower, the structure is also simpler, and the cost is saved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module and a display device with the backlight module. Background technique [0002] In liquid crystal display, such as some mobile phones, the display screen needs a backlight module to provide a light source. The light source of the backlight module is generally provided by an LED light bar, and then the light guide plate and optical film are used to make the brightness of the backlight uniform. [0003] For some special-shaped backlight modules with cutouts and notches, the brightness of the edge area is uneven due to the uneven brightness received by the light source at the edge of the notch area. Therefore, in the prior art, in order to ensure the brightness of the notch area, a separate The auxiliary light source controls the brightness of the main light source and the auxiliary light source through the main board to display the content of the corresponding are...

Problems solved by technology

However, the sub-light source is set at the gap position of the backlight module. Considering the placement and wiring of the sub-light source at this position, it is necessary to additionally set up a shading area to block the sub-light source and related control circuits at the gap position, and the display area at this position cannot be used. Large, and the size of the gap cannot be made small, and the frame cannot be made small, which will affect the realization of the narrow frame. In addition, the control circuit must be set separately at the position of the secondary light source, which makes the main board circuit of the display device more complicated and increases the cost.
