Abstract: A supporting column fixed on a light bar, the light bar and a backlight module are provided. The supporting column includes: a base plate; a supporting sheet arranged on a side of the base plate, wherein one end of the supporting sheet is connected with the base plate and the supporting sheet is configured to be rotatable in a direction towards the base plate and a direction away from the base plate, so that the supporting sheet has a first state and a second state, and an included angle between the supporting sheet and the base plate in the first state is smaller than that in the second state; and a clamping part configured to be clamp-fitted with the supporting sheet upon the supporting sheet being in the second state so as to fix the supporting sheet.

Abstract: Provided are a backlight module, a display panel and a display apparatus. The backlight module includes a back plate, including a bottom plate and a frame surrounding the bottom plate; at least one light bar, fixed on an inner sidewall of the frame, wherein a gap is formed between an end portion of the light bar and the inner sidewall of the frame in an extension direction of the light bar; and a reflector sheet, disposed in the frame and on the bottom plate, wherein at least one first sidewall of the reflector sheet is provided with at least one first protrusion, the first protrusion being extended from the first sidewall on which the first protrusion is disposed towards an inner sidewall of the frame opposite to the first sidewall on which the first protrusion is disposed, and the first protrusion being disposed in the gap.

Abstract: A backlight module and a displaying device. The backlight module comprises a backplane, a reflector plate and a light guide plate that are disposed in sequence, a light strip disposed on a first side of the light guide plate, and a plurality of positioning assemblies disposed at two ends of the first side of the light guide plate respectively, wherein each light guide assembly comprises a positioning element disposed on the backplane and a guide surface disposed at a corner of the first side of the light guide plate. The positioning assemblies are disposed on the first side, where the light strip is located, of the light guide plate, such that the light guide plate will be driven to move away from support members under a reactive force of the positioning elements when expanding.
