Problems solved by technology

[0005] In the prior art, the trend of full screen has become the mainstream trend in the development of display devices, and the corner positions of many display devices and the corner positions of the corresponding display areas have also begun to use rounded corners. When the light bar is installed, due to the limitation of the rounded edge, it is difficult for the light bar to extend to the edge of the display device. Close to both sides of the light guide plate, resulting in dark shadows in the backlight module near the edge of the irregular shape, resulting in shadow problems in the backlight module, resulting in poor display effect of the display device

Embodiment Construction

[0052] In order to improve the light-emitting angle of the light-emitting diode, reduce the dark shadow of the backlight module, and improve the display effect of the display device, an embodiment of the present invention provides a light-emitting diode, a backlight module and a display device. In order to make the purpose, technical solution and advantages of the present invention clearer, the following examples are given to further describe the present invention in detail.

[0053] Such as figure 1 as shown, figure 1 It is a schematic diagram of a partial cross-sectional structure of a backlight module according to an embodiment of the prior art, showing a backlight module in the prior art. In the prior art, with the development of the narrow frame of the mobile terminal, the edge of the backlight module begins to have a special-shaped edge 01. More commonly, the corners of the backlight module are rounded edges. When setting the light bar 02 of the backlight module Due to...

Abstract

The disclosure provides a light emitting diode, a backlight device and a display device. The light emitting diode includes a bracket and a light emitting diode chip. The bracket includes two first side plates arranged opposite to each other, two second side plates arranged opposite to each other, and a base plate, where at least one of the two first side plates is a light-transmitting side plate. The light emitting diode chip is arranged in a receptacle, where the receptacle is formed by the two first side plates arranged opposite to each other, the two second side plates arranged opposite to each other, and the base plate.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a light emitting diode, a backlight module and a display device. Background technique [0002] A liquid crystal display device is a flat panel display device. Its working principle is to use the liquid crystal material to modulate light under the action of an electric field to produce various light and dark changes to form images. Since the liquid crystal material itself does not emit light, all liquid crystal display devices require a special backlight module. [0003] The backlight module is one of the key components of the liquid crystal display device. The main function of the backlight module is to provide uniform and high-brightness backlight for the liquid crystal panel. The basic principle of the backlight module is to convert the commonly used point or line illuminants into high-brightness and uniform gray-scale surface illuminants through an effective light mechanism,...
