The light-directing structure 30 includes a plurality of stripe-shaped electrochromic cells 310, and when a part of the electrochromic cells 310 change color from a transparent state under the action of a driving voltage, the peep-proof angle of the display panel may change.

Optionally, the distance D1 between two adjacent electrochromic cells 310 satisfies the condition that D1 is greater than or equal to 0.02mm and less than or equal to 0.1 mm.
For example, the distance D1 between two adjacent electrochromic cells 310 may be set to satisfy that D1 is greater than or equal to 0.02mm and less than or equal to 0.1mm, so as to ensure that the display device realizes the display panel with adjustable peeping-proof angle through the electrochromic cells and ensure the display effect of the display screen of the display panel.

When the distance between two adjacent electrochromic units 310 is too wide, the electrochromic units 310 arranged in an array are connected to a driving voltage, and at the moment, the electrochromic units 310 are all switched from a transparent state to a black state, but because the distance between two adjacent electrochromic units 310 is too wide, the electrochromic units in the black state cannot shield the light ray with a large emergent angle of the backlight module, so that the peeping-proof angle-adjustable range of the display panel can be influenced.
Optionally, on the basis of the above embodiment, fig. 6 is a schematic diagram of a film structure of a light directing structure provided in the embodiment of the present invention, as shown in fig. 6, the light directing structure 30 includes a first electrode layer 31, an electrochromic layer 32 and a second electrode layer 33 stacked in sequence, when a driving voltage is applied to the first electrode layer 31 and the second electrode layer 33, the electrochromic layer 32 is changed from a transparent state to a non-transparent state, and when the driving voltage is not applied to the first electrode layer 31 and the second electrode layer 33, the electrochromic layer 32 is changed from the non-transparent state to the transparent state.
Illustratively, as shown in fig. 6, the light-directing structure 30 includes a first electrode layer 31, an electrochromic layer 32, and a second electrode layer 33, which are sequentially stacked, wherein the electrochromic layer 32 is capable of generating a stable and reversible color shade change under the action of an applied electric field. The electrochromic layer may be formed on the glass substrate by magnetron sputtering, vacuum evaporation. When a certain voltage is applied between the first electrode layer 31 and the second electrode layer 33 of the light-directing structure 30, the material of the electrochromic layer 32 undergoes an oxidation-reduction reaction under the voltage, and thus undergoes a color change.
For example, the electrochromic layer 32 may change from a transparent color to red when a voltage applied between the first electrode layer 31 and the second electrode layer 33 of the light-directing structure 30 changes from 0V to 1V. The electrochromic layer 32 may change from a transparent color to black when a voltage applied between the first electrode layer 31 and the second electrode layer 33 of the light-directing structure 30 is changed from 0V to 5V. When the voltage applied between the first electrode layer 31 and the second electrode layer 33 of the light-directing structure 30 is changed from 5V to 0V, the electrochromic layer 32 may change from black back to a transparent color, and so on.
As can be seen from the above, the material of the electrochromic layer 32 has a transparent state and a colored state. Wherein the transparent state can be the configuration of the light directing structure 30 when not energized and the colored state can be the configuration of the light directing structure 30 when energized. In the non-energized transparent state, the electrochromic layer 32 may be transparent to light. While in the energized, colored state, the electrochromic layer 32 may block the passage of light. The first electrode layer 31, the second electrode layer 33 and the electrochromic layer 32 in the light-directing structure 30 are all in a transparent state when not energized, i.e. the light-directing structure 30 as a whole is in a transparent state when not energized.
Optionally, on the basis of the foregoing embodiment, fig. 7 is a schematic diagram of a film structure of another light directing structure provided in the embodiment of the present invention, and as shown in fig. 7, the light directing structure further includes a first protection layer 34 and a second protection layer 35, the first protection layer 34 is located on the side of the first electrode layer 31 away from the electrochromic layer 32, and the second protection layer 35 is located on the side of the second electrode layer 33 away from the electrochromic layer 32.
Illustratively, as shown in fig. 7, the first electrode layer 31 and the second electrode layer 33 of the photo-alignment structure 30 are protected by the first protective layer 34 and the second protective layer 35 by disposing the first protective layer 34 on the side of the first electrode layer 31 of the photo-alignment structure 30 away from the electrochromic layer 32 and disposing the second protective layer 35 on the side of the second electrode layer 33 of the photo-alignment structure 30 away from the electrochromic layer 32.
Optionally, the first electrode layer 31 includes a plurality of first electrode strips 311 arranged in parallel along the first direction X, the second electrode layer 33 includes a plurality of second electrode strips 331 arranged in parallel along the first direction X, the electrochromic layer 32 includes a plurality of electrochromic structures 321 arranged in parallel along the first direction X, in each electrochromic unit 310, a vertical projection of the first electrode strip 311 on the array substrate 210 overlaps a vertical projection of the second electrode strip 331 on the array substrate 210, and a vertical projection of the electrochromic structure 321 on the array substrate 210 overlaps a vertical projection of the first electrode strip 311 on the array substrate 210.
In the embodiment of the present disclosure, the electric field formed between the first electrode layer 31 and the second electrode layer 32 of the light directing structure 30 is used to control whether the electrochromic layer 32 is in a transparent state or a black state, that is, the electrochromic layer 32 is a transparent region or a non-transparent region, and the division of the transparent region and the non-transparent region is related to the structure of the first electrode layer 31 and the second electrode layer 33 and the power-on condition. Therefore, by setting the vertical projection of the first electrode bar 311 on the array substrate 210 of each electrochromic unit 310 in the light-directing structure 30 to overlap the vertical projection of the second electrode bar 331 on the array substrate 210, the vertical projection of the electrochromic structure 321 on the array substrate 210 overlaps the vertical projection of the first electrode bar 311 on the array substrate 210, and by controlling whether an electric field is formed between the first electrode bar 311 and the second electrode bar 331 corresponding to a certain electrochromic unit 310, the electrochromic structure 321 is controlled to be in a transparent state or a black state.
For convenience of explanation of technical solutions in the embodiments of the present disclosure, an X-Y coordinate system as in fig. 6 is established with a plane of a surface on which the light-directing structures 30 are located, and in the following embodiments of the present disclosure, after the first electrode layer 31 and the second electrode layer 33 are configured to apply a voltage to the electrochromic layer 32 with a direction perpendicular to the Y axis as a first direction, the electrochromic layer 32 forms a plurality of alternately arranged non-light-transmitting regions and light-transmitting regions in a stripe shape according to an arrangement of the first electrode stripes 311 and the second electrode stripes 331, and the non-light-transmitting regions and the light-transmitting regions are distributed along the first direction X. In this manner, the viewing angle of the light directing structure is narrowed in the direction parallel to the X axis, and the display device can narrow the viewing angle of the displayed image in the direction parallel to the X axis.
Optionally, on the basis of the above embodiment, fig. 8 is a schematic structural diagram of another display device provided in the embodiment of the present invention, as shown in fig. 8, the light directing structure 30 is located between the backlight module 10 and the array substrate 210, one side of the array substrate 210 close to the liquid crystal layer 230 is sequentially provided with a pixel circuit layer 240, a light adjusting layer 250 and a planarization layer 260, and a refractive index of the light adjusting layer 250 is different from a refractive index of the planarization layer 260.
Optionally, the light adjusting layer 250 includes a plurality of protruding structures 251 arranged in an array on a side thereof close to the planarization layer 260.
For example, as shown in fig. 8, a pixel circuit layer 240, a light adjusting layer 250 and a planarization layer 260 are sequentially disposed on a side of the array substrate 210 close to the liquid crystal layer 230, and a refractive index of the light adjusting layer 250 is different from a refractive index of the planarization layer 260, and light incident on the liquid crystal layer 230 is adjusted by the light adjusting layer 250, wherein the side of the light adjusting layer 250 close to the planarization layer 260 includes a plurality of protruding structures 251 arranged in an array, and since an included angle is formed between at least a portion of contact surfaces of the protruding structures 251 and the planarization layer 260, when light passes through the light adjusting layer 250 after passing through the light-directing structure 30, an incident angle of the light passing through the light adjusting layer 250 to the planarization layer 260 is changed due to the difference between the refractive index of the light adjusting layer 250 and the refractive index of the planarization layer 260. For example, when the refractive index of the light adjustment layer 250 is smaller than the refractive index of the planarization layer 260, the angle of the light emitted from the light adjustment layer 250 after passing through the planarization layer 260 is larger, so that the image display at a large viewing angle is improved, and the effect of a wide viewing angle is ensured. On the contrary, when the refractive index of the light adjustment layer 250 is larger than that of the planarization layer 260, the angle of the light emitted from the light adjustment layer 250 after passing through the planarization layer 260 is small, the peeping prevention effect of the narrow viewing angle is improved, and the personal privacy is ensured.
It should be noted that the illustration exemplarily shows a plurality of protruding structures 251 arranged in an array on a side of the light adjustment layer 250 close to the planarization layer 260, and the embodiment of the invention does not limit the specific shape of the protruding structures 251.
Optionally, the first electrode layer is electrically connected to a common electrode layer of the display panel, or the second electrode layer is electrically connected to a common electrode layer of the display panel.
The electrochromic layer 32 may change from a transparent color to black color due to a voltage applied between the first electrode layer 31 and the second electrode layer 33 of the light-directing structure 30 changing from 0V to 5V. When the voltage applied between the first electrode layer 31 and the second electrode layer 33 of the light-directing structure 30 is changed from 5V to 0V, the electrochromic layer 32 can be changed from black to transparent, so that the first electrode layer 31 can be electrically connected with the common electrode layer of the display panel 20, when the display panel 20 is in a display state, the first electrode layer 31 is at a fixed potential signal, and the voltage difference between the first electrode layer 31 and the second electrode layer 33 is changed from 0V to 5V by controlling the voltage signal of the second electrode layer 33, thereby changing the color of the electrochromic layer 32. Since the first electrode layer 31 is electrically connected to the common electrode layer of the display panel 20, a signal line can be reduced to supply a voltage signal to the first electrode layer 31.
In other embodiments, the second electrode layer 33 may be electrically connected to a common electrode layer of the display panel 20, and the common electrode layer may be used to provide a common voltage signal to the second electrode layer 33.
Optionally, the width of the pixel electrode of the display panel along the first direction is a1, a1> D2.
By setting the width a1 of the pixel electrode of the display panel along the first direction to be greater than the width D2 of the electrochromic cell 310, the distortion phenomenon of the display picture of the display panel is avoided.
