Problems solved by technology

[0005] In the side-type backlight module of the prior art, in order to convert the point light source emitted by the LED light-emitting chip into a surface light source after passing through the light guide plate, so as to provide sufficient backlight source for the display panel to be bonded, the area of ​​the light guide plate Usually equal to the area of ​​the display panel; but when the area of ​​the display panel is larger, the area of ​​the light guide plate is also larger, which is not conducive to the manufacture of the light guide plate. At the same time, because the overall thickness of the light guide plate is usually thinner, the area of ​​the light guide plate is smaller The larger the size, the easier it is to bend, which will affect the light guiding effect of the light guide plate

Abstract

An embodiment of the invention provides a backlight source module and a display device and relates to the technical field of display. The backlight source module comprises a back panel, at least two light guide strips and at least one LED luminous chip. The light guide strips are parallelly arranged at an interval on the same side of the back panel, and the LED luminous chips are arranged near incident surfaces of the light guide strips. The embodiment of the invention further provides production methods of the backlight source module and the display device comprising the same.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 201410025907.3 and the invention title "a backlight module and display device" submitted to the China Patent Office on January 20, 2014, the entire contents of which are incorporated herein by reference. Applying. technical field [0002] The invention relates to the field of display technology, in particular to a backlight source module and a display device. Background technique [0003] At present, LED light-emitting diodes are the backlight light source of mainstream liquid crystal display devices. [0004] The backlight module can be divided into direct-type and side-type. Compared with the direct-type backlight module, the side-type backlight module has a light bar with multiple LED light-emitting chips arranged on one side of the light guide plate or On both sides, the light is incident from the side of the light guide plate, and the point light source emitted by ...
