Specifically, the display screen 1 includes a pixel structure 10 and a privacy structure 11. The pixel structure 10 includes a plurality of pixel units 100 arranged in an array and at intervals, each pixel unit 100 includes a central region 100a and an edge region 100b located at the periphery of the central region 100a, a spacing region 101 is provided between two edge regions 100b of two adjacent pixel units 100, the peep-proof structure 11 is disposed at one side of the pixel structure 10, the peep-proof structure 11 includes a driving electrode 110 and a plurality of charged light-shielding particles 111, the driving electrode 110 is used for driving the plurality of charged light-shielding particles 111 to switch between a first state corresponding to the spacing region 101 and a second state corresponding to the spacing region 101 and the edge region 100b of the plurality of pixel units 100. Referring to fig. 1, fig. 2 and fig. 4, in the first state, the peep-proof structure 11 forms a plurality of first light-transmitting regions 11a corresponding to the central regions 100a and the edge regions 100b of the plurality of pixel units 100, respectively, and the light of each pixel unit 100 is emitted through each corresponding first light-transmitting region 11 a. Referring to fig. 2, 3 and 5 together, in the second state, the peep preventing structure 11 forms a plurality of second light transmitting regions 11b corresponding to the central regions 100a of the plurality of pixel units 100, respectively, and light of each pixel unit 100 is emitted through each corresponding second light transmitting region 11b, wherein fig. 1 shows that the peep preventing structure 11 is in the first state, fig. 2 shows that the peep preventing structure 11 includes a plurality of charged light shielding particles 111, a part of the charged light shielding particles 111 is in the first state, and the rest of the charged light shielding particles 111 is in the second state, fig. 1 shows that the peep preventing structure 11 is in the second state, fig. 4 shows that the plurality of charged light shielding particles 111 is in the first state, and light paths of several light rays are exemplarily shown by thick solid lines and arrows, and fig. 5 shows that the plurality of charged light shielding particles 111 is in the second state, and light paths of several light rays are exemplarily shown by thick solid lines and arrows.

It should be noted that the aforementioned "state of the plurality of charged light-shielding particles 111 corresponding to the spacing region 101" refers to a state in which the projections of the plurality of charged light-shielding particles 111 on the pixel structure 10 are all located in the spacing region 101 along the direction from the peep-proof structure 11 to the pixel structure 10, and the aforementioned "state of the charged light-shielding particles 111 corresponding to the spacing region 101 and the edge region 100b of the plurality of pixel units 100" refers to a state in which the projections of the plurality of charged light-shielding particles 111 on the pixel structure 10 are located in the spacing region 101 and the edge region 100b along the direction from the peep-proof structure 11 to the pixel structure 10, and the aforementioned "light of the pixel unit 100" includes light emitted from the pixel unit 100 or light emitted to the pixel unit 100.

As shown in fig. 6, the inventors have found that, since most of the light paths of the large-angle outgoing light rays of the light rays of each pixel unit 100 pass through the position corresponding to the edge region 100b, and most of the light paths of the small-angle outgoing light rays do not pass through the position corresponding to the edge region 100b, the display panel 1 includes the peep preventing structure 11 having the first state and the second state, in the first state, the charged light shielding particles 111 correspond to the spacing regions 101, so that the peep preventing structure 11 forms the first light transmitting regions 11a corresponding to the central regions 100a and the edge regions 100b of the plurality of pixel units 100, so that the charged light shielding particles 111 can avoid most of the light rays of the pixel units 100, the influence of the peep preventing structure 11 on the display effect of the display panel 1 is small, so that the display panel 1 is in the normal display mode, in the second state, the charged light shielding particles 111 correspond to the edge regions 100b of the spacing regions 101 and the plurality of pixel units 100, so that the peep preventing structure 11 forms the second light transmitting regions 100a light path corresponding to the central regions 100a thick line of the plurality of pixel units 100, and the light rays of the display panel 100 are reduced in the display angle display mode, so that the light rays of the display panel 1 are absorbed by the light path, and the light rays of the light rays absorbed by the light shielding particles 11, and the light shielding bar is reduced angle of the display panel 1, thereby the display panel 1, and the light rays, and the display panel 1.

In actual use, according to specific use conditions and use requirements, a user may control the driving electrode 110 of the display screen 1 through a key, software, an instruction, or the like, or the display screen 1 may automatically control the driving electrode 110, so that the driving electrode 110 drives the charged light-shielding particles 111 to switch between the first state and the second state, and the display screen 1 can be switched between the normal display mode and the peep-proof display mode.

It should be noted that the "large-angle light" and the "small-angle light" described above are specifically determined according to the viewing angle of the display screen 1 in the peep-proof display mode. Specifically, the pixel unit 100 has a main light emitting direction P perpendicular to a side surface thereof, an included angle θ is formed between a propagation direction of the light and the main light emitting direction P, when θ is less than or equal to a visible angle and is equal to or greater than 0 °, the light is a small-angle light, and when θ is greater than the visible angle, the light is a large-angle light.

In addition, because the peep-proof structure 11 provided by the embodiment can form the second light-transmitting area 11b for each pixel unit 100 in the second state, compared with the mode of attaching the peep-proof film adopted in the related art, the peep-proof structure 11 provided by the application has the advantages that the transmittance of small-angle light of each pixel unit 100 is higher in the second state, so that the light utilization rate of the display screen in the peep-proof display mode is higher, the display brightness is higher, and the display picture effect is better.

Alternatively, the charged light-shielding particles 111 may perform the function of shielding light in different ways.

As shown in fig. 5, in an alternative embodiment, the charged light-shielding particles 111 may include light-absorbing particles, for example, dark particles such as charged black, dark gray, dark brown, etc., so that the charged light-shielding particles 111 can achieve the function of blocking light from passing through by absorbing light, and since the absorbed light does not become stray light and continues to emit to other places, light crosstalk can be reduced, so as to improve the display effect of the display panel 1.

As shown in fig. 7, in another alternative embodiment, the charged light-shielding particles 111 may include reflective particles, for example, light-colored particles such as charged white, light gray, light yellow, and the like, so that the charged light-shielding particles 111 can reflect light to block light from passing through, and thus in the second state, large-angle light can be reflected multiple times by the charged light-shielding particles 111, so that part of the large-angle light is adjusted to be small-angle light and emitted through the second light-transmitting area 11b, thereby improving the utilization rate of light, so as to improve the display brightness of the display screen 1 in the peep-proof display mode, and further improve the display effect of the display screen 1, where the light paths of several light rays are exemplarily shown by thick solid lines and arrows in fig. 7.

In some embodiments, the driving electrode 110 may include a transparent electrode to reduce the influence of the driving electrode 110 on light, so as to reduce the influence of the driving motor on the display effect of the display screen 1.

Specifically, the driving electrode 110 may be energized to generate an electric field to generate an attractive force or a repulsive force to the charged light-shielding particles 111 to perform a function of driving the charged light-shielding particles 111 to move to different positions.

Referring to fig. 1, 5 and 8, for example, the driving electrode 110 may include a first electrode 110a, a plurality of second electrodes 110b and a third electrode 110c, each of the first electrode 110a, the plurality of second electrodes 110b and the third electrode 110c may be a transparent electrode, the first electrode 110a and the second electrode 110b are disposed on the same side and the third electrode 110c is disposed on the other side along the direction from the pixel structure 10 to the peep-proof structure 11, the first electrode 110a is disposed corresponding to the spacing region 101, the plurality of second electrodes 110b are disposed corresponding to the edge regions 100b of the plurality of pixel units 100, the second electrode 110b is spaced apart from the first electrode 110a, the third electrode 110c is disposed corresponding to at least the first electrode 110a and the second electrode 110b, in the first state, the first electrode 110a and the third electrode 110c are used for energizing, so that the surface of the first electrode 110a adsorbs the charged particles 111, in the second state, the first electrode 110a and the second electrode 110b are used for energizing the pixel structure along the direction from the pixel structure 10, wherein the pixel structure is shown in the first state.

It should be noted that, the aforementioned "first electrodes 110a are disposed corresponding to the spacing regions 101", which means that the projections of the first electrodes 110a on the pixel structure 10 are all located in the spacing regions 101 along the direction from the privacy protecting structure 11 to the pixel structure 10, and the aforementioned "second electrodes 110b are disposed corresponding to the edge regions 100b of the pixel units 100", which means that the second electrodes 110b correspond to the pixel units 100, respectively, and the projections of the second electrodes 110b on the pixel structure 10 along the direction from the privacy protecting structure 11 to the pixel structure 10 are at least partially located in the edge regions 100b of the pixel units 100.

Alternatively, the first electrode 110a and the second electrode 110b of the peep-proof structure 11 are located at a side close to the pixel structure 10, and the third electrode 110c of the peep-proof structure 11 is located at a side far from the pixel structure 10, so that the charged light-shielding particles 111 are closer to the pixel structure 10, and in the second state, the charged light-shielding particles 111 shield light from a position closer to the edge region 100b, so as to more accurately block light with a large angle.

In a direction from the central region 100a to the edge region 100b, the second electrode 110b has a dimension a, which may be larger in order to enable the charged light-shielding particles 111 adsorbed on the surface of the second electrode 110b to effectively block light rays with large angles, and in order to avoid that the charged light-shielding particles 111 adsorbed on the surface of the second electrode 110b block light rays with too many small angles to affect the display effect of the display screen 1 in the privacy display mode, the dimension a may not be too large, and based on this, optionally, the dimension a may satisfy: 5um ≦ a ≦ 10um, for example, dimension a may be: 5um, 5.5um, 6um, 6.5um, 7um, 7.5um, 8um, 8.5um, 9um, 9.5um or 10um, etc.

In order to form the entire peep-proof structure 11 as a stable structure, the peep-proof structure 11 may further include other connecting and sealant structures.

In addition, by doping the charged light-shielding particles 111 into the filling medium, the resistance of the charged light-shielding particles 111 in the accommodating space 115 can be increased, so that the charged light-shielding particles 111 are not easy to move without additional electric field force, the driving electrode 110 is not required to be powered on, the charged light-shielding particles 111 can be maintained in the current state, the energy consumption of the peep-proof structure 11 is low, and the overall energy consumption of the display screen 1 is also low.

Optionally, the first cover plate 112 and the second cover plate 113 may be transparent cover plates, so as to reduce the influence of the first cover plate 112 and the second cover plate 113 on the light, thereby reducing the influence of the first cover plate 112 and the second cover plate 113 on the display effect of the display screen 1.
