Fixing method for removing abnormal sound of backlight light tube

Abstract

The invention provides a fixing method for removing the abnormal sound of a backlight light tube, which comprises the following steps of: externally arranging a photo-permeable adhesive tape or an adhesive strip in a winding way at a clamping part of the backlight light tube, wherein the outer wall of the backlight light tube and the clamping part are separated from each other through the photo-permeable adhesive tape or the adhesive strip. The fixing method for removing the abnormal sound of the backlight light tube is relatively simple, can realize the volume production of the backlight module, can avoid the direct contact between the backlight light tube and the clamping part which are two rigid components since the photo-permeable adhesive tape, or the adhesive strip and the elastic glue are flexible bodies, and can avoid the abnormal sound even with small-quantity vibrating friction.

Description

technical field [0001] The invention belongs to the fixing technology of a backlight lamp tube, and in particular relates to a fixing method capable of eliminating the resonance abnormal sound of the backlight lamp tube of a liquid crystal panel. Background technique [0002] The liquid crystal display system is mainly assembled by a liquid crystal panel, a signal board, a circuit board, a speaker and a housing with a frame. Since the liquid crystal panel is composed of various parts made of different materials, considering the influence of assembly tolerance and thermal expansion and contraction, there is inevitably a certain gap at the combination interface of each part. When the speakers of the liquid crystal display system emit sounds of different frequency bands, it is likely to cause resonance of the liquid crystal panel components, and the vibration and friction of adjacent components will cause abnormal sounds. Inside the direct-lit liquid crystal panel, the lamp tu...

Problems solved by technology

like figure 1 as shown, figure 1 It is a schematic diagram of the fixing structure of the backlight tube in the prior art. The backlight tube 110 is fixed by a set of buckle parts, and the two buckle parts are distributed and fixed on the backboard 130. The buckle parts include a column and a hook. The hooks 122, 124 of the two fasteners and the columns 121, 123 jointly fix the backlight tube 110 on the backboard 130. This method will cause extrusion stress on the fixing part of the backlight tube by the hooks and columns. Due to the stress and the possible gap between the lamp holder and the lamp holder, this part is prone to resonant abnormal sound, which may even cause the lamp tube to jump off and break
