Embodiment 1

[0030] Such as Figure 1 to Figure 5 As shown, this embodiment provides a display device, including:

[0031] at least one display structure 1;

[0032] The backlight structure is used to provide a light source 2 for the display structure 1. The backlight structure includes: a light source 2 (such as an LED light bar), a first light guide plate 3, and at least one optical structure layer 4. The light source 2 passes through the incident light of the first light guide plate 3 The surface 31 transmits the light into the first light guide plate 3, the optical structure layer 4 is located between the first light guide plate 3 and the display structure 1, the optical structure layer 4 is provided with scattering particles 44, and the light emitting surface of the first light guide plate 3 The light emitted from 32 uniformly goes to the display structure 1 through the optical structure layer 4 .

Abstract

The invention provides a display device, belongs to the technical field of display, and can at least partially solve the problem that an existing display device has different display brightness at different angles. The display device comprises at least one display structure; the backlight structure is used for providing a light source for the display structure, the backlight structure comprises the light source, a first light guide plate and at least one optical structure layer, the light source transmits light rays into the first light guide plate through a light incident surface of the first light guide plate, the optical structure layer is located between the first light guide plate and the display structure, and scattering particles are arranged in the optical structure layer; and light emitted from the light emitting surface of the first light guide plate is uniformly emitted to the display structure through the optical structure layer.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display device. Background technique [0002] With the development of display technology, the types of display devices are also increasing, such as transparent display devices, double-sided display devices, and the like. [0003] A display device in the prior art at least includes a display panel, a light guide plate, a glass protection backplane, a light source, an optical film layer, and the like. However, due to the structural defects of the display device in the prior art, the display device has the problem that the display brightness is different between the display surface and the non-facing display surface, such as the problem of insufficient brightness at the front viewing angle and high brightness at the side viewing angle. Contents of the invention [0004] The present invention at least partly solves the problem of different display brightness at diff...
