Problems solved by technology

Therefore, it is easy to break the lamp tube or cause deformation of the clamping arm due to improper assembly force
And when the offset of the size causes the entrance of the lamp tube to be too large, it is difficult to hold the lamp tube well, and it is easy to loosen due to vibration or movement, resulting in damage or position shift of the lamp tube
[0007]The above situations will cause inconvenience in the assembly of the backlight module and damage to the components, which will result in increased assembly man-hours and production costs, and may lead to a shortened lamp life. reduced, resulting in poor product quality

Abstract

The invention provides a light tube positioning device and a backlight module using the positioning device for holding the light tube. The positioning device comprises an upper branch part and a lower branch part, wherein, a holding mouth is formed between the upper branch part and the lower branch part for holding the light tube. Besides, at least one of the upper branch part and the lower branch part is elastic to offer buffer effect to the light tube and reduce the inertia impact on and the cracking possibility of the light tube.

Description

technical field [0001] The invention relates to a lamp tube positioning device and a backlight module using the lamp tube positioning device; in particular, it relates to a lamp tube positioning device for a liquid crystal display and a backlight module using the lamp tube positioning device. Background technique [0002] In recent years, liquid crystal displays (Liquid Crystal Displays) have become the mainstream of various display devices. Liquid crystal display devices are used in a large number of electronic products, such as televisions, monitors for personal computers and laptops, mobile phones and digital cameras, etc. In a liquid crystal display device, a backlight module (Backlight Module) is used to supply bright and evenly distributed light sources so that the liquid crystal display device can display images normally. Backlight modules can be divided into edge-lighting backlight modules and bottom-lighting backlight modules, each of which is suitable for liquid c...
