Problems solved by technology

The backlight of this structure can make the uniformity of backlight brightness better, but the disadvantage is that due to the requirement of light mixing distance, the thickness of the backlight is relatively large, and the energy consumption is relatively high
[0005] Therefore, in the prior art TFT-LCD display, there is still a lack of a backlight with uniform brightness and light and thin structure.

Embodiment Construction

[0022] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] The backlight source according to the specific embodiment of the present invention includes:

[0024] A plurality of light sources and at least one light guide plate. The light sources are embedded in the light guide plate and are separately arranged at different positions of the light guide plate for guiding the emitted light into the light guide plate from different positions.

[0025] Using the backlight source according to the specific embodiment of the present invention, the light source can be separately arranged on different positions of the light guide plate, thereby dividing the light guide plate into a plurality of areas, each area includes a light source, and the light source is embedded in the light guide plate. The divergent light ...

Abstract

The invention provides a backlight source and a display device. The backlight source comprises multiple light sources and at least one light guide plate, wherein the light sources are embedded into the light guide plate and further arranged in various positions of the light guide plate respectively for the conduction of light emitted by the light sources into the light guide plate from various positions; the light sources can be arranged in the various positions of the light guide plate, so that the light guide plate is divided into multiple areas; as each area of the backlight source comprises one light source, multiple side incidence type backlight sources are formed; and the brightness can be adjusted according to the areas. Therefore, the backlight source not only can guarantee the brightness evenness of a whole backlight source system, but also has the advantages of lightness and thinness like a side incidence type backlight source structure.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a backlight source and a display device. Background technique [0002] In recent years, LED backlights have gradually become the mainstream of TFT-LCD (Thin Film Field Effect Transistor-Liquid Crystal Display) displays. The most common ones include edge-lit backlights and direct-lit backlights. The two types of backlights have their own advantages and disadvantages. [0003] Such as figure 1 It is a schematic diagram of the structure of a side-lit backlight in the prior art, including a light guide plate 1 and an LED lamp 2. The LED lamp 2 is arranged on the side of the light guide plate 1, so that the emitted light enters the light guide plate 1 from the side and is converted into a planar shape light source. The LED lamp 2 is located on the side of the light guide plate 1. The advantage is that the thickness of the backlight source is small and the weight is light. As the s...
