Example Embodiment

[0043] The present invention is further detailed in conjunction with the accompanying drawings and examples. It will be appreciated that the specific embodiments described herein are merely illustrative of the invention and are not limited thereto. It will also be noted that in order to facilitate the description, only the parts associated with the present invention are shown in the drawings rather than all structures.

[0044] figure 1 It is a structural diagram of the backlight module proposed in the prior art. figure 2 It is a schematic diagram of the light intensity distribution of the light emitting diode in the prior art backlight module. Combine figure 1 with figure 2 Distance figure 1 The backlight module group includes diffusion plate 1, light-emitting diode 2 and reflection sheet 3 of different colors, wherein the light-emitting diode 2 of different colors is disposed on the reflection sheet 3. Since the conventional light-emitting diode 2 is the strongest in the direct...

Abstract

The invention discloses a backlight module and a display panel, the backlight module comprises a reflector plate, a diffusion plate and a plurality of light-emitting units, each light-emitting unit is arranged between the reflector plate and the diffusion plate, each light-emitting unit comprises a top light-emitting surface, a bottom surface and a plurality of side light-emitting surfaces which are approximately parallel to the diffusion plate, the vertical projection of each top light-emitting surface on the diffusion plate is smaller than the vertical projection of each bottom surface on the diffusion plate, a gap or contact exists between each top light-emitting surface and the diffusion plate, and the included angle between at least one side light-emitting surface and the bottom surface is an acute angle, so that good brightness uniformity and better image quality effect can be realized; and the thickness of a liquid crystal display product is thinner.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular to a backlight module and a display panel. Background technique [0002] As consumers have higher requirements for the image quality and product form of LCD products, ultra-thin and high-quality images have gradually become the standard configuration of high-end LCD products. Among them, the number of partitions is currently increased through the direct-down scheme to achieve high-quality images, and further in order to make the display effect better, quantum dot membranes will be used, but the quantum dot membranes have a certain thickness, which will increase the thickness of liquid crystal display products; in addition , in order to achieve a better picture quality effect, the backlight is changed from the original white LED to red LED, green LED and blue LED, but due to the LED characteristic problem, the color uniformity is poor. [0003] Furthermore...
