Direct type led backlight light-bar fixing method

Abstract

The invention discloses a straight down type LED backlight LB (Light Bar) fixing way. The fixing way comprises the following steps: firstly, arranging a folding piece at the edge of a backing plate where an LB is mounted, forming a plurality of single-clamp groove bayonets inside the backing plate, and forming one double-clamp groove bayonet at the edge opposite to the folding piece on the backing plate, wherein the folding piece, the single-clamp groove bayonets and the double-clamp groove bayonet are located on one straight line vertical to the length direction of the LB; secondly, locating and mounting the LB on the backing plate; and thirdly, sheathing one end of a double-strand rope on the folding piece at the edge of the backing plate, and enabling the rope to pass through a plurality of single-pin locating pins, wherein the quantity of the single-pin locating pins is consistent with the quantity of the single-clamp groove bayonets, and the single-pin locating pins are inserted into the single-clamp groove bayonets; the other end of the rope is fixed on a handle of a double-pin locating pin; the single-pin locating pins can be inserted and combined with the single-clamp groove bayonets; and the double-pin locating pin can be inserted and combined with the double-clamp groove bayonet, and the double-pin locating pins can rotate around the axis of the handle for 360 degrees to tension the rope. The fixing way disclosed by the invention has the advantages that the rope is used for fixing, time and labor are saved during operation of a production line, and quickness and convenience are realized.

Description

technical field [0001] The invention belongs to the field of liquid crystal electronics, and in particular relates to a Light-Bar fixing method. Background technique [0002] The LEDs in the backlight of the direct-lit liquid crystal display are arranged in a matrix. Usually, several LEDs form a strip-shaped Light-Bar (LB), and the Light-Bar is installed on the backplane of the display. At present, the installation of the direct-lit LED backlight Light-Bar is mainly screw-locked, such as figure 1 and figure 2 shown. Taking a 55-inch LCD monitor as an example, 150 screws are needed to fix the LED Light-Bar, which consumes a lot of man-hours and manpower, and it is easy to miss due to too many tasks. What's more important is that screw locking and other compression point fixing methods are used, and the local deformation of the LED Light-Bar substrate is relatively large after being heated.
