Problems solved by technology

[0004] However, since the upper polarizer and the lower polarizer are used in the existing transparent liquid crystal display module, this makes the overall transmittance of the transparent liquid crystal display module relatively low, and, in order to increase the uniformity of light output, the existing The light guide plate in the transparent liquid crystal display module is also provided with a film layer (for example, a prism film, a scattering film, a reflector, etc.), which will further reduce the overall transmittance of the transparent liquid crystal display module, resulting in the transparent liquid crystal The transparent display effect of the display module is poor

Abstract

The invention discloses a backlight source and a liquid crystal display module and relates to the technical field of display. The technical problem that the conventional transparent liquid crystal display module is poor in transparent display effect is solved. The backlight source comprises a light guide plate, wherein a light source component is arranged on the side face of the light guide plate; and a plurality of collimation light extraction components are arranged on a light-exiting surface of the light guide plate or a bottom surface opposite to the light-exiting surface. The backlight source provided by the invention is applied to the liquid crystal display module.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight source and a liquid crystal display module. Background technique [0002] Transparent display module refers to a display module that can form a transparent display state so that the viewer can see the scene behind it. More commonly, it can be used in department store display windows, refrigerator door perspectives, car front windshields, vending machines, etc. Various fields have synergistic effects such as display, interaction, and advertising. Moreover, due to its unique use scenarios and intelligent scene switching, transparent display modules have attracted more and more attention in the application of special display fields. [0003] At present, a more common transparent display module is a transparent liquid crystal display module. A light source for providing light is provided. When the transparent liquid crystal display module displays the picture, the ligh...
