背光模组及显示装置Backlight module and display device

技术领域technical field

本申请涉及显示技术领域,具体涉及一种背光模组及显示装置。The present application relates to the field of display technology, in particular to a backlight module and a display device.

背景技术Background technique

目前,客户往往要求背光源具有高亮度、低功耗的特点。然而,现有常规的背光源往往不能满足客户要求。特别是,窄边框机种等背光源在经过模组老化(Aging Mode)后,也就是在出货前发生较为严重的变形。这一变形将直接导致导光板(Light Guide Plate,LGP)与发光二极管(Light Emitting Diode,LED)的发光面之间出现0.1mm左右的间隙。上述0.1mm左右的间隙将使得发光二极管的出光亮度降低10%左右,最终背光源的亮度也将无法满足客户的要求。At present, customers often require the backlight to have the characteristics of high brightness and low power consumption. However, existing conventional backlight sources often cannot meet customer requirements. In particular, backlights such as narrow bezel models undergo serious deformation after module aging (Aging Mode), that is, before shipment. This deformation will directly lead to a gap of about 0.1 mm between the light guide plate (Light Guide Plate, LGP) and the light emitting surface of the light emitting diode (Light Emitting Diode, LED). The aforementioned gap of about 0.1 mm will reduce the brightness of the light emitting diode by about 10%, and finally the brightness of the backlight source will not be able to meet the requirements of customers.
