Document Type and Number:
WIPO Patent Application WO/2014/029141
Kind Code:
A1
Abstract:
A side light backlight module (200) comprises a back panel (201), a heat sink (202) arranged on the back panel (201), and a light bar (205) mounted on the heat sink (202). A light guide plate (208) is arranged above the back panel (201). A plurality of back panel clamping hooks (203) is arranged on the back panel (201); and the heat sink (202) is hooked and pressed by the back panel clamping hooks (203). An elastic body (207) is arranged between the back panel (201) and the heat sink (202). The elastic body (207) applies, to the heat sink (202), a horizontal elastic force towards the back panel clamping hooks (203), so as to position the heat sink (202) in the width direction of the heat sink (202). The side light backlight module (200) can avoid warpage of the light guide plate (208) caused by expansion, and ensure optical coupling efficiency.
