Problems solved by technology

Due to the requirements of the assembly sequence, the optical films 16 and the plastic frame 12 cannot be completely sealed, but there must be a very small opening 100, and the light may leak from the opening 100 without sufficient excitation times. , so that the edge positions of the optical films 16 produce chromatic aberration

Abstract

The embodiment of the invention discloses a backlight module. The embodiment of the invention comprises a housing unit which is provided with at least one reflecting surface and forms an accommodating space in a surrounding manner, a light source arranged in the accommodating space, a light guide plate installed in the accommodating space, and a quantum dot enhancement film arranged one the light guide plate in an overlapping manner and located in the accommodating space. The light guide plate comprises a light ingoing edge facing to the light source and a surrounding edge being connected with the light ingoing edge and forming an edge of the light guide plate in a surrounding manner together with the light ingoing edge. A reflecting surface of the housing unit faces to the light guide plate to increase the passing number of light passing through the quantum dot enhancement film, sufficient correction light is inspired, and a chromatic aberration of an edge position of a display is thus improved.

Description

Technical field [0001] The present invention relates to a backlight module, and particularly relates to a backlight module that can improve the edge chromatic aberration phenomenon of the display. Background technique [0002] Quantum Dot Enhancement Film (QDEF) is an optical component currently used in backlight modules to make the color of the display more accurate. The principle is to set a considerable number of two kinds of quantum dots on the film, and use blue light as the backlight source. When the blue light is irradiated on the two kinds of quantum dots, it will be converted into red light and green light. The red and green light generated will be It is mixed with blue light into white light. By changing the ratio of converting blue light into red light and green light, the color mixing effect can be closer to the actual color, thus making the display color more accurate. [0003] Refer to figure 1 , Is a prior art backlight module 1 equipped with a quantum dot enhanceme...
