Embodiment 1

[0040] In the embodiment of the present application, a backlight module is provided.

[0041] Further, the backlight module is applied to a liquid crystal display device. The liquid crystal display device is composed of a liquid crystal panel and a backlight module in an embodiment of the present invention.

[0042] In the embodiment of the present application, the liquid crystal display device can be applied to various electronic products, such as mobile phones, notebook computers, or PADs.

[0043] Furthermore, the liquid crystal panel includes the following parts: upper and lower polarizers, upper and lower glass substrates, thin film transistor (thin film transistor, TFT), liquid crystal, color filter, ITO transparent conductive layer, frame glue and other one or more parts .

[0044] In subsequent embodiments, the functions of each part of the liquid crystal panel will be described in detail, but the embodiment of the present application only introduces the backlight mo...

Embodiment 2

[0059] In the embodiment of the present application, a dual display screen structure is introduced.

[0060] Further, please see Figure 5 , the dual-screen display structure consists of three parts: a first backlight module 1 , a second backlight module 2 , and a liquid crystal panel 3 .

[0061] exist Figure 5 Among them, the second backlight module 2 is arranged under the first backlight module 1 , and the liquid crystal panel 3 is arranged between the first backlight module 1 and the second backlight module 2 .

[0062] Wherein, the first backlight module 1 and the second backlight module 2 cannot work at the same time.

[0063] Furthermore, when the first backlight module 1 is in the working state, the second backlight module 2 is in the non-working state. At this time, the liquid crystal panel 3 receives and utilizes the first white light source emitted by the first backlight module 1 .

[0064] When the second backlight module 2 is in the working state, the first ba...

Abstract

The invention discloses backlight modules, a double-display-screen structure and electronic equipment. The double-display-screen structure comprises the first backlight module, the second backlight module and a liquid crystal panel, the second backlight module is overlaid below the first backlight module, the liquid crystal panel is arranged between the first backlight module and the second backlight module, and when the first backlight module is in the work state and the second backlight module is in the nonworking state, the liquid crystal panel receives and utilizes a first white light source emitted by the first backlight module. Or, when the second backlight module is in the work state and the first backlight module is in the nonworking state, the liquid crystal panel receives and utilizes a second white light source emitted by the second backlight module.

Description

technical field [0001] The invention relates to liquid crystal display technology, in particular to a backlight module, a double display screen structure and electronic equipment. Background technique [0002] At present, in order to increase the functions of electronic products, many electronic products on the market are equipped with a second display screen in addition to a main display screen, so as to provide users with more convenient operations. For example, a general foldable mobile phone usually has inner and outer screens, wherein the inner screen is used as the main information screen during operation, and the outer screen obtains part of the information in real time. With the rapid development of mobile Internet technology, many mobile Internet devices such as tablet computers have gradually adopted a dual-screen display design to obtain a better user experience. [0003] The existing dual-screen display design is to connect two display screens back to back. Suc...
