Background technique

With the development of informatization, communication and networking, thin, light and small portable mobile products have become important electronic products in daily life, and liquid crystal flat panel displays (Liquid Crystal Display, LCD) in products have become important components. Since the liquid crystal display itself does not emit light, it needs an external surface light source to provide a uniform and high-brightness display effect. According to the light source mechanism, the liquid crystal display in the prior art can be divided into two types, please refer to Figure 1 and Figure 2, respectively It is a backlight module and a front light module. Among them, the backlight module 1a is mainly used in transmissive or semi-transparent panels, providing a light source 10a for the liquid crystal panel, usually a point or linear light source, and a reflector 11a, which enters the light guide plate 13a through the reflector 12a, and transforms the distribution of the light source into The surface light source with uniform brightness, and then through the uniform light effect of the diffuser sheet 14a and the light collection effect of the rhombic sheet 15a to improve the brightness and uniformity of the light source; the front light source module 2a is mainly used for the reflective LCD panel 24a, and its principle is to The point or linear light source 20a enters the light guide plate 22a through the reflector 21a, and uses the once-formed microstructure 23a such as a triangular prism on the front surface of the light guide plate 22a to transform the light source into a uniformly bright surface light source.
