Problems solved by technology

[0002] The liquid crystal display device uses liquid crystal to provide image display. It is usually composed of a liquid crystal panel, a backlight module, related digital circuits, and a power supply. To prevent light leakage, the LED light bar in the backlight module is close to the LCD panel. It will crush the LED lamp beads on the LED light bar, affect the light emission of the LED lamp beads, thereby affecting the backlight effect and the quality of the liquid crystal display device

Embodiment Construction

[0013] refer to figure 1 , a backlight module, comprising a cooling block 1 and an LED light bar 2, the LED light bar 2 is provided with LED lamp beads 22, the cooling block 1 is provided with a groove 11 matching with the LED light bar 2, and the LED light bar 2 is provided with There is a protrusion 21 whose end surface is higher than the LED lamp bead 22 .

[0014] Insert the LED light strip 2 into the groove 11 in the heat dissipation block 1, and fix the LED light strip 2 on the heat dissipation block 1. The upper end surface of the LED light strip 2 is higher than the protrusion 21 of the LED to protect the LED light beads 22. , preventing the LED light bar from being squeezed, thereby effectively ensuring the luminous effect of the LED lamp bead 22, the backlight effect and the quality of the liquid crystal display device.

[0015] In this embodiment, preferably, the heat dissipation block 1 is provided with a heat dissipation plate 12, and the heat dissipation plate 1...

Abstract

The invention discloses a backlight module which comprises a heat dissipation block and an LED light bar. The LED light bar is provided with an LED light bead, the heat dissipation block is provided with a groove matched with the LED light bar, and the LED light bar is provided with a protrusion with the end face higher than that of the LED light bead. The LED light bar is inserted into the groove of the heat dissipation block, the LED light bar is stably fixed on the heat dissipation block, the upper end face of the LED light bar is higher than the protrusion of an LED, the function of protecting the LED light bead is achieved, the LED light bar is prevented from being extruded, and therefore the lighting effect of the LED light bead, the backlighting effect and the quality of a liquid crystal display device are effectively guaranteed.

Description

technical field [0001] The invention relates to a backlight module. Background technique [0002] The liquid crystal display device uses liquid crystal to provide image display. It is usually composed of a liquid crystal panel, a backlight module, related digital circuits, and a power supply. To prevent light leakage, the LED light bar in the backlight module is close to the LCD panel. It will crush the LED lamp beads on the LED light bar, affect the light emission of the LED lamp beads, thereby affecting the backlight effect and the quality of the liquid crystal display device. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a backlight module with a simple structure, and protrusions are provided on the LED light bar, which can prevent the LED light beads from being squeezed. [0004] The technical solution adopted by the present invention to solve its technical problems: [0005] A backlight modu...
