The invention discloses an optical module and a display device. The optical module comprises a light guide plate, a refraction substrate and at least one luminous element, the light guide plate is provided with a first in-light face, an out-light face and at least one second in-light face, the first in-light face and the out-light face are opposite, the second in-light faces are arranged between the first in-light face and the out-light face, the second in-light faces are correspondingly provided with the luminous elements, and the refraction substrate is opposite to the out-light face. The luminous elements selectively face the second in-light faces corresponding to the luminous elements and emit first light rays, moreover, and the light guide plate can reflect the first light rays which at least partly irradiate the second in-light faces of the light guide plate, so that the first light rays emit from the light guide plate and enter the refraction substrate, wherein the refractive index of the refraction substrate is larger than or equal to that of the light guide plate. By means of the optical module, switching between a peep-proof mode and a normal mode can be achieved, and the peep-proof effect is improved.

A light guide plate, a method of fabricating a light guide plate, a backlight module and a display device are disclosed. The light guide plate includes a light guide layer and a grating layer. The light guide layer includes a light incident surface, a light exit surface, and a bottom surface opposite to the light exit surface. The grating layer is disposed on a side of the light guide layer with the light exit surface being on the side and including a plurality of grating strips. The bottom surface is provided with a plurality of optical dots. The plurality of optical dots are configured to deflect light rays from the light incident surface toward the grating strips. The plurality of grating strips are configured to deflect light rays emitted from the light exit surface toward a normal line of the light exit surface.

The invention relates to a display module which comprises a backlight module and a display module body.The display module further comprises a light ray conversion module located between the backlight module and the display module body.The light ray conversion module comprises a first transparent conductive membrane, a second transparent conductive membrane and a peep-prevention structure.The first transparent conductive membrane is attached to the backlight module.The second transparent conductive membrane is attached to the display module body.The peed-prevention structure is arranged between the first transparent conductive membrane and the second transparent conductive membrane and fixed on the first transparent conductive membrane, and is perpendicular to the backlight module.The light ray conversion module further comprises liquid crystals, wherein the part between the first transparent conductive membrane and the second transparent conductive membrane is filled with the liquid crystals.The display module can be converted between the visual sharing function and the peep-prevention function and is small in thickness.The invention further relates to a convertible peep-prevention displayer.

The invention discloses a peep-proof display device. According to one embodiment of the invention, the device comprises a display screen; a diffusion film which is disposed at a display side of the display screen; and an adjustment apparatus which is used for enabling the diffusion film and / or display screen to move in a direction intersected with the plane of the display screen, so as to enable the relative distance between the diffusion film and the display screen to change. According to the embodiment of the invention, the device achieves a peep-proof function under the condition that the display brightness of a vertical view angle is not affected, and facilitates the reduction of the power consumption.

The invention discloses a display device and a display method, which belong to the field of display technology. The display device includes: a display panel and a grating structure. The display panel includes: a pixel layer including alternately arranged first pixel groups and second pixel groups; the grating structure includes: alternately arranged opening regions and light-shielding regions. Wherein, the orthographic projection of the opening area on the display panel is located in the first pixel group, and the orthographic projection of the light-shielding area on the display panel covers the second pixel group. When the display device is in the anti-peeping display mode, a plurality of first pixel groups display a target image, and a plurality of second pixel groups display an interference image different from the target image; when the display device is in a shared display mode, a plurality of first pixel groups display The target image is displayed, and the plurality of second pixel groups display the same shared image as the target image. The display mode of the display device is effectively enriched.
