Problems solved by technology

[0002] Existing breathing display backlights generally include a light guide plate and at least one LED light bar, and the light guide plate includes a light-emitting surface and a light-incoming surface. Usually, the light-emitting surface and the light-incoming surface are located on opposite sides. Therefore, generally, the light-guiding plate One side is used as the light-incoming surface, and the other side is used as the light-emitting surface. The light emitted by the LED elements of the LED light bar enters the inside of the light guide plate through the light-incoming surface of one side, and then is exported from the light-emitting surface on the other side. The light it exports is prone to dazzling visual effects

Embodiment Construction

[0034] Please refer to Figure 1 to Figure 5 As shown, it shows the specific structure of a preferred embodiment of the present invention, which is a soft light TV breathing display backlight, including a light guide plate 10 and an LED strip 20 detachably connected to the light guide plate 10 ,in:

[0035] The light guide plate 10 is an atomized light guide plate. In this embodiment, the light guide plate 10 is formed by mixing and preparing PC and a light diffusing agent, and then injection molding, so as to improve the scattering effect of light entering the light guide plate 10 . It should be noted that the mass percentage of the light diffusing agent is 2.5-3.5%, preferably, 3% of the light diffusing agent is used. The light guide plate 10 has an L-shaped structure. The light guide plate 10 has a vertical portion 11 and a horizontal portion 12 integrally extending forward along the bottom end of the vertical portion 11. The vertical portion 11 and the horizontal portion...

Abstract

The invention discloses a respiration type display backlight of a soft light television. The respiration type display backlight comprises a light guide plate and an LED light strip connected to the light guide plate detachably. The light guide plate has an L-shaped structure and has a vertical portion and a horizontal portion extending forward along the bottom of the vertical portion in an integrated manner; and the vertical portion and the horizontal portion extend horizontally in a left-right direction. The LED strip includes an FPC board and a plurality of LED elements arranged on the FPC board; the FPC board is disposed at the front side and / or rear side of the vertical portion; light emitted by the LED elements enter downwardly from the vertical portion, is transmitted forward throughthe rear end of the horizontal portion, and then is emitted outward from the front end surface of the horizontal portion. Since the light emitted by the LED elements enter from the vertical portion and is emitted through the horizontal portion, light entering the light guide plate changes gradually and thus one type of brightness is converted into another type of brightness to generate a soft visual effect.

Description

technical field [0001] The present invention relates to the technology in the field of backlights, in particular to a soft-light TV breathing display backlight. Background technique [0002] Existing breathing display backlights generally include a light guide plate and at least one LED light bar, and the light guide plate includes a light-emitting surface and a light-incoming surface. Usually, the light-emitting surface and the light-incoming surface are located on opposite sides. Therefore, generally, the light-guiding plate One side is used as the light-incoming surface, and the other side is used as the light-emitting surface. The light emitted by the LED elements of the LED light bar enters the inside of the light guide plate through the light-incoming surface of one side, and then is exported from the light-emitting surface on the other side. The light it exports is prone to dazzling visual effects. [0003] Therefore, a new technical solution needs to be developed to...
