Abstract

The invention provides a light guide plate assembly, a lateral-entrance backlight source module and a display device, relating to the technical field of display. Local dynamic light modulation can be realized in different areas of a backlight source via the light guide plate assembly, and the image display contrast is improved. The light guide plate assembly comprises a first substrate, a second substrate opposite to the first substrate, and light modulation units between the first and second substrates; each light modulation unit comprises a first electrode, a second electrode and an electrophoretic capsule layer, the first and second electrodes are arranged close to the first and second substrates respectively, an electric field is formed between the first and second electrodes, the electrophoretic capsule layer is composed of electrophoretic capsules, each electrophoretic capsule comprises white electrophoretic particles and black electrophoretic particles, the white and black electrophoretic particles are dispersed in a transparent disperse medium, and the charge carried by the white electrophoretic particles is opposite to that carried by the black electrophoretic particles; and the first substrate is placed in the light extraction side of the light guide plate assembly, and the first substrate and the first electrode are transparent.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a light guide plate assembly, a side-entry backlight source module, and a display device. Background technique [0002] The backlight module is an indispensable component in an LCD (Liquid Crystal Display, liquid crystal display device), and one of its core structures is a light guide plate. Such as figure 1 As shown, the light emitted by the point light source or line light source located on the side of the light guide plate (as shown by the dotted arrow in the figure) enters the light guide plate, and then irradiates the scattering network points on the bottom surface of the light guide plate for scattering, and then the point light source or The surface light source is converted to an upward emitting surface light source, thus providing a uniform backlight for the LCD. [0003] In the prior art, the dots on the bottom of the light guide plate are usually formed by dotting t...
