Abstract
The present invention relates to the technical field of display devices, and provides a light guide structure and a backlight module. The light guide structure includes a light incident portion for incident light of external light sources, a light guide portion for guiding light, and a lattice point unit for reflecting and scattering light; incident light grooves for receiving light sources are formed in the light incident portion; the light guide portion includes a first light guide region and a second light guide region which are integrally formed; the light incident portion is arranged on one side of the first light guide region; the lattice point unit includes a plurality of lattice points arranged in the first light guide region and the second light guide region; the density of the lattice points is increasing with increase in the distance from the light guide portion to the light incident portion, and the size of the lattice points is increasing; optical characteristics such as the light emission uniformity of the light guide portion are uniform everywhere, and changes of optical effects of the light guide portion are uniform everywhere in use, and in this way, the uniformityof outgoing light of the first light guide region and the second light guide region is ensured; and when the light guide structure is used in a display device, display effects of various display regions of the display device are more even, and a good use experience is achieved.
Description
technical field [0001] The present invention relates to the technical field of display devices, more specifically, to a light guide structure and a backlight module. Background technique [0002] At present, liquid crystal display devices are widely used in various electronic products as display components of electronic equipment. Due to their non-self-luminous characteristics, liquid crystal displays require backlight modules to display their brightness. Therefore, backlight modules are a must in liquid crystal display devices. It is an indispensable and important component, and the luminous characteristics of the backlight module are closely related to the light guide structure. [0003] Backlight modules are divided into side-type backlight modules and direct-type backlight modules according to the position of the light source. In the direct type backlight module, the light source is arranged behind the display panel, and the display panel is provided with a backlight th...
