Embodiment Construction

[0029] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0030] The edge-lit LED backlight of the present invention includes a plurality of LED particles arranged along the sides of the display screen, and only three of the four sides of the display screen 1 are respectively provided with a plurality of the LED particles. In this embodiment, by selecting any three sides of the display screen 1 to set LED particles according to the brightness requirements of the display screen, this side-light LED backlight design method can be called a U-shaped light incident method. The side-lit LED backlight with U-shape light incident mode satisfies the brightness quality of the display screen, and at the same time effectively controls the number of LED particles ...

Abstract

The invention discloses a side light type LED backlight source and a display device, wherein the side light type LED backlight source is characterized in that a plurality of LED beads are respectively arranged on only three side edges of the peripheral side edges of a display screen. The invention enables the light incident mode of the side light type LED backlight source to be more reasonable, and improves the brightness quality effect of the display screen. The side light type LED backlight source is beneficial to the cost saving under the condition of ensuring the display quality of the display screen and simultaneously improving the brightness uniformity of the LED backlight source.

Description

technical field [0001] The invention relates to the field of televisions, in particular to a side-light LED backlight source and a display device. Background technique [0002] The side-lit LED backlight includes a backlight cavity, the front of the backlight cavity is an optical module, and the back is a fixed plate, on which multiple LED particles are installed, that is, LED lights. In actual design, the LED backlight is arranged on the LCD screen The surrounding edges of the display screen are combined with a light guide plate, which is located on the back of the display screen. When the LED backlight module emits light, the light emitted from the edge of the display screen is transported to the central area of ​​the screen through the light guide plate, so that the whole has enough The amount of backlight that allows the LCD screen to display images. There are two advantages of adopting edge-lit LED backlight. One is to use a smaller number of LED particle light sources...
