Abstract

The invention discloses a backlight module and a display module. The backlight module comprises a backlight source, a light guide plate and a light guide plate, the light guide plate comprises a side light incoming surface, a top light outgoing surface, a bottom reflecting surface and a side reflecting surface, and the side light incoming surface is arranged corresponding to the backlight source; wherein an ink layer is arranged on the side reflecting surface, the ink layer comprises a white ink layer and a black ink layer, and the black ink layer is arranged on the side, away from the side reflecting surface, of the white ink layer. The white ink layer can enable the light from the light guide plate to be reflected back into the light guide plate on the side reflecting surface, so that the light utilization rate of the light guide plate is improved; the black ink layer 132 can absorb light, reduce light leakage from the edge of the light guide plate, improve the problem of poor optics of bright lines on the edge, and achieve good visual effect and product quality.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a backlight module and a display module including the backlight module. Background technique [0002] At this stage, the development trend of medium and large-size LCD displays is still the demand for narrow bezels, light and thin, high brightness, and low power consumption. In response to the trend of narrow bezels, the current traditional liquid crystal displays mainly use side-type backlight module structures as the basis. Mainly, the side of the light guide plate is made of ordinary white reflective structure or silver reflective structure, which is easy to leak light and cause a relatively large loss of brightness. The main reason is that the reflectivity of the side reflective material is not high enough, and the reflective layer will have light transmission. , The reflective material will transmit light and cause light loss, which will reduce the display brightn...
