Abstract

The invention discloses a backlight module, a display panel and a display device. The backlight module comprises a first light-transmitting base plate, a first reflector surface and a second reflector surface, wherein the first light-transmitting base plate is projected and coincided on a light emitting surface; the first reflector surface and the second reflector surface are arranged on the first light-transmitting base plate and are oppositely arranged at an interval; the first reflector surface is coincided with the projection of a shading adhesive tape; the second reflector surface is used for totally reflecting and then emitting the vertical emergent light from the light emitting surface to the first reflector surface; the first reflector surface is used for emitting, totally reflecting and then emitting the light reflected by the second reflector surface; a plurality of light holes are uniformly distributed in the second reflector surface; the extending directions of the light holes are vertical to the light emitting surface. According to the invention, the lighting path on an edge position of the light emitting surface of the backlight module is changed, the frame-free illuminating effect is achieved and the display effect is promoted.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module, a display panel, and a display device. Background technique [0002] The LCD display itself does not emit light. In order to clearly see the content displayed on the LCD display, it needs the support of the backlight module to obtain color rendering. The backlight module is an optical component that exists inside the liquid crystal display. It is composed of necessary optical components such as a light source, a film, a reflector, and a back plate, and is packaged by a plastic frame. [0003] During the process of realizing the present invention, the inventors found that there are at least the following technical problems in the prior art: the existing backlight module cannot achieve the effect of lighting without borders. Contents of the invention [0004] In view of this, the object of the present invention is to provide a backlight module, a display pan...
