Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] The liquid crystal display itself does not emit light, and generally realizes display through a backlight module. In order to understand the backlight module provided by the embodiment of the present invention more clearly, the types and basic structures of the existing backlight module are firstly introduced.

[0027] In the prior art, backlight modules are divided into two types, side-type backlight modules and direct-type backlight modules, according...

Abstract

The invention provides a backlight module, a manufacturing method thereof and a display device, relates to the technical field of display, and solves the problems that an existing display device can only rely on power provided by other power supply devices, and the display device is not integrated with a power generating unit. The backlight module comprises a light guide plate and at least one power generating unit. Each power generating unit comprises a first electrode, a second electrode and a power generating layer located between the first electrode and the second electrode. Each power generating unit is disposed on one side opposite to the light emitting direction of the light guide plate. The first electrode of at least one of the power generating unit is in direct contact with the light guide plate. Each first electrode can reflect light, and one side, facing the light guide plate, of the first electrode is a reflecting surface.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module, a manufacturing method thereof, and a display device. Background technique [0002] The existing display devices all provide electric energy through an external power supply device. For example, a TV mainly provides electrical signals through an external power supply. Another example is a mobile phone, although it itself includes a battery for storing electric energy, it must be charged to the battery by an external power source before use, and when the battery power is exhausted, it must be charged by an external power source to continue to use. [0003] It can be seen that the existing display devices must rely on external power supply devices to achieve display, especially for mobile display devices such as mobile phones, which brings problems such as inconvenient use. Contents of the invention [0004] Embodiments of the present invention provide a ba...
