Description

Technical Field

[0001] This application relates to the field of displays, and in particular, to a device with adjustable viewing range, a driving method, a display module, and a device. Background Art

[0002] Panel display technology has been widely used, and the wide viewing angle of the display panel meets people's requirements for viewing effects. At the same time, the wide viewing angle of the display panel is also likely to lead to the leakage of private display information. Therefore, in order to protect the privacy of users, it is necessary to perform anti-peeping design on the display panel, such as: externally attaching an anti-peeping film, electro-optic birefringence technology, and dual-backlight viewing angle control technology, etc.

[0003] However, currently, whether it is passive anti-peeping or active anti-peeping in anti-peeping display technology, when the display panel is in the anti-peeping display mode, the viewing angle is fixed and unchanged. At this time, if the user's viewing angle changes and is in the anti-peeping angle, the user himself cannot observe the display content, thereby reducing the user experience. For example, in the anti-peeping mode, when the user's viewing angle is adjusted from the display area to the anti-peeping area (i.e., the area where the display content cannot be viewed normally), the user cannot view the display content.

[0004] Although in the related art, the anti-peeping mode of some display panels can be adjusted, when the user's viewing angle is adjusted from the display area to the anti-peeping area, if you want to view the real content, you need to adjust the anti-peeping mode, which still reduces the user experience and is not intelligent enough.

Detailed implementation manners

[0057] For a better understanding of the technical solution of the present application, the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0058] It should be clear that the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts belong to the scope of protection of the present application.

[0059] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms of "a", "the" and "said" used in the embodiments of the present application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0060] It should be understood that the term " / and / " used herein is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, a and / or b may represent: a exists alone, a and b exist simultaneously, and b exists alone. In addition, the character " / " herein generally represents an "or" relationship between the associated objects before and after.

[0061] In order to enable the visible range to change with the change of the user's viewing angle, thereby improving the user experience and intelligence, an embodiment of the present application proposes a visible range adjustable device, a driving method, a display module, and a device.

[0062] An embodiment of the present application provides a visible range adjustable device. The visible range adjustable device includes a first state. In a possible implementation, the first state may be an anti-peeping state. When the visible range adjustable device is in the first state, the visible range of the visible range adjustable device changes with the change of the area where the target recognition feature of the target user is located. That is: when the visible range adjustable device is in the first state, when the area where the target recognition feature of the target user changes, the visible range of the visible range adjustable device will change. Among them, the target recognition feature of the target user includes at least one of the target facial feature and the target eye feature.

[0063] In the embodiment of the present application, the target user refers to a user who meets the preset conditions. For example, the target user may be the owner of the device or other individuals or groups authorized by the owner to use the device. The target recognition feature refers to a recognition feature that meets the preset conditions. The target recognition feature may be a relevant feature for receiving display information. For example, the target recognition feature may be a facial feature and / or an eye feature. It should be noted that the facial feature and the eye feature mentioned above are only illustrative and not limiting. That is, in addition to the facial feature and the eye feature mentioned above, the target recognition feature may also be other forms of features, such as a head feature, a gesture, a fingerprint feature, etc. Therefore, the target recognition feature of the target user may also include at least one of the target head feature, the target gesture feature, and the target fingerprint feature.

[0064] In this embodiment, when the visible range adjustable device is in the first state, the visible range adjustable device can achieve an adaptive change in the visible range, that is, it can make its visible range change with the change of the target recognition feature of the target customer. When the visible range adjustable device is used in combination with a display panel, the anti-peeping range can be adjusted: when the area where the line of sight of the permitted observer changes, the display angle of the display panel can be changed, so as to achieve the purpose of adjusting the anti-peeping range.

[0065] As Figure 1 shown, in a possible implementation, the visible range adjustable device 100 includes: a first substrate 101, a first visible range adjustment unit 130, and a second visible range adjustment unit 140.

[0066] The first visible range adjustment unit 130 is located on one side of the first substrate 101, and the first visible adjustment unit is perpendicular to the first substrate 101. The first visible range adjustment unit 130 includes a visible state and a light-shielding state. When the first visible range adjustment unit 130 is in the light-shielding state, the visible range of the visible range adjustable device 100 is the first range. In this implementation, since the first visible adjustment unit is perpendicular to the first substrate 101, when the first visible adjustment unit is in the light-shielding state, the line of sight or display light perpendicular to the first substrate 101 is within the first range, and part of the line of sight will be blocked by the first visible range adjustment unit 130, so that this part of the line of sight cannot receive the display light and is in a dark area. Therefore, the area outside the first range is a non-visible area, that is, the anti-peeping area. At this time, an observer located outside the first range cannot receive the display light and thus cannot view the display content of the display panel 201.

[0067] The second visible range adjustment unit 140 is located on the side of the first substrate 101 facing the first visible range adjustment unit 130, that is, the first visible range adjustment unit 130 and the second visible range adjustment unit 140 are on the same side of the first substrate 101. The included angle between the second visible range adjustment unit 140 and the first substrate 101 is an acute angle or an obtuse angle, that is, the second visible range adjustment unit 140 is not perpendicular to the first substrate 101. The second visible range adjustment unit 140 includes a visible state and a light-shielding state. When the second visible range adjustment unit 140 is in the light-shielding state, the visible range of the visible range adjustable device 100 is the second range, and the first range is different from the second range. The difference between the second range and the first range means that the visible range of the visible range adjustable device 100 is different and has changed.

[0068] In this implementation, when the second visible range adjustment unit 140 is in the light-shielding state, it will block part of the line of sight (the line of sight outside the second range). This part of the line of sight cannot receive the display light because it is blocked by the second visible range adjustment unit 140, so that this part of the line of sight is non-visible and the display content cannot be seen. Similarly, when the second visible range adjustment unit 140 is in the light-shielding state, it can ensure that the line of sight within the second range can receive the display light and is thus visible. The difference between the first range and the second range means that by controlling the light-shielding state and visible state of both the first visible range adjustment unit 130 and the second visible range adjustment unit 140, the adjustment of the visible range can be achieved.

[0069] In a possible implementation, when the visible range adjustable device 100 is in the first state, the visible range of the visible range adjustable device 100 changes with the change of the area where the target recognition feature of the target user is located, including:

[0070] Such as Figure 2aAs shown, when the visible range adjustable device 100 is in the first state and the target recognition feature of the target user is within the first range, the first visible range adjustment unit 130 is in a light-shielding state, and the second visible range adjustment unit 140 is in a visible state. When the first visible range adjustment unit 130 is in a light-shielding state and the second visible range adjustment unit 140 is in a visible state, the visible range of the visible range adjustable device 100 is the first range α.

[0071] As Figure 2b Or Figure 2c As shown, when the visible range adjustable device 100 is in the first state and the target recognition feature of the target user is within the first area A1, the second visible range adjustment unit 140 is in a light-shielding state, and the first visible range adjustment unit 130 is in a visible state. The first area A1 is within the second range and outside the first range. When the second visible range adjustment unit 140 is in a light-shielding state and the first visible range adjustment unit 130 is in a visible state, the visible range of the visible range adjustable device 100 is the second range.

[0072] In this implementation, since in some embodiments, there is an overlapping area between the first range and the second range. The so-called overlapping area refers to the area that is both within the first range and within the second range. For example, the area M shown in the figure is the overlapping area. For the convenience of control, when the target recognition feature of the target user is within this overlapping range, the first visible range adjustment unit 130 is in a light-shielding state, and the second visible range adjustment unit 140 is in a visible state; when the target recognition feature of the target user is within the first area, the second visible range adjustment unit 140 is in a light-shielding state, and the first visible range adjustment unit 130 is in a visible state.

[0073] As Figure 1As shown, in a possible implementation, the visible range adjustable device 100 includes a first electrode layer 110 and a second electrode layer 120. The first electrode layer 110 is located on one side of the first substrate 101, and the second electrode layer 120 is located on the side of the first electrode layer 110 facing away from the first substrate 101. The first visible range adjustment part 130 includes: a first electrode 111, a second electrode 121, and a plurality of first electrochromic bodies 131. The first electrode 111 is located on the first electrode layer 110. The second electrode 121 is located on the second electrode layer 120. An insulating layer 102 is included between the first electrode layer 110 and the second electrode layer 120. In a possible implementation, the insulating layer includes an insulating part and a plurality of first channels. Among them, the number of the first channels corresponds one-to-one to the number of the first electrochromic bodies 131, and the first electrochromic bodies 131 are located in the first channels. It should be understood that the insulating part refers to the part of the insulating layer except the channels. The plurality of first channels are parallel to each other, and the first channels are perpendicular to the first substrate 101. The plurality of first electrochromic bodies 131 are parallel to each other, and the first electrochromic bodies 131 are perpendicular to the first substrate 101. The first end of the first electrochromic body 131 is electrically connected to the first electrode 111, and the second end of the first electrochromic body 131 is electrically connected to the second electrode 121.

[0074] One of the first electrode 111 and the second electrode 121 is a positive electrode, and the other is a negative electrode. The first electrode 111 and the second electrode 121 are respectively connected to a power supply circuit. The power supply circuit is used to supply electrical energy to the electrochromic body and control the conduction and cut-off of the circuit between the first electrode 111 and the second electrode 121. The first electrochromic body 131 is a current-induced electrochromic body. When the circuit between the first electrode 111 and the second electrode 121 is in a conducting state, the current flowing through the first electrochromic body 131 causes it to change color, that is, to change the light transmission state of the first electrochromic body 131. Among them, the light transmission state of the first electrochromic body 131 includes a light-shielding state and a light-transmitting state. When the first electrochromic body 131 is in the light-shielding state, the first visible range adjustment part 130 is in the light-shielding state; when the first electrochromic body 131 is in the light-transmitting state, the first visible range adjustment part 130 is in the visible state.

[0075] In a possible implementation, the first electrode 111 is a positive electrode and the second electrode 121 is a negative electrode. The first electrode 111 is a patterned electrode, and its patterned shape corresponds to the end pattern of the first electrochromic body 131 electrically connected to it.

[0076] As Figure 2bAs shown, in a possible implementation, the second range β includes the first sub-range β1. The second visual range adjustment unit 140 includes: a third electrode 122 and a plurality of second electrochromic bodies 141. The third electrode 122 is located in the second electrode layer 120, and the third electrode 122 is electrically insulated from the second electrode 121. The insulating layer further includes a plurality of second channels. The number of second channels is equal to the number of second electrochromic bodies 141. One second electrochromic body 141 is disposed in each second channel. The plurality of second channels are parallel to each other. The plurality of second electrochromic bodies 141 are parallel to each other. The extending direction of the second channels intersects with the extending direction of the first channels, and the intersection angle is non-right angle. The extending direction of the second electrochromic bodies 141 intersects with the extending direction of the first electrochromic bodies 131. The first end of the second electrochromic body 141 is electrically connected to the first electrode 111, and the second end of the second electrochromic body 141 is electrically connected to the third electrode 122. Wherein, the second visual range adjustment unit 140 being in the light-shielding state includes the second electrochromic bodies 141 being in the light-shielding state. When the second electrochromic bodies 141 are in the light-shielding state, the visual range of the visual range adjustable device 100 is the first sub-range.

[0077] One of the first electrode 111 and the third electrode 122 is the positive electrode, and the other is the negative electrode. The first electrode 111 and the third electrode 122 are respectively connected to a power supply circuit. The power supply circuit is used to supply electrical energy to the electrochromic body and control the conduction and cut-off of the circuit between the first electrode 111 and the third electrode 122. The second electrochromic body 141 is a current-induced electrochromic body. When the circuit between the first electrode 111 and the third electrode 122 is in the conduction state, the current flowing through the second electrochromic body 141 causes it to change color, that is, changes the light-transmitting state of the second electrochromic body 141. Wherein, the light-transmitting state of the second electrochromic body 141 includes a light-shielding state and a light-transmitting state. When the second electrochromic body 141 is in the light-shielding state, the second visual range adjustment unit 140 is in the light-shielding state; when the second electrochromic body 141 is in the light-transmitting state, the second visual range adjustment unit 140 is in the visible state.

[0078] In this implementation, sharing the first electrode 111 by the first electrochromic body 131 and the second electrochromic body 141 can save one electrode, reduce the wiring difficulty, and thus help reduce the cost.

[0079] As Figure 2cAs shown, in a possible implementation, the second range β includes a second sub-range β2. The first sub-range β1 is different from the second sub-range β2. The second visual range adjustment unit 140 includes: a first independent electrode 123 and a plurality of third electrochromic bodies 142. The first independent electrode 123 is located in the second electrode layer 120 and is electrically insulated from the second electrode 121 and the third electrode 122 respectively. The insulating layer includes a plurality of third channels. The number of the third channels is equal to the number of the third electrochromic bodies 142. Each third channel includes one third electrochromic body 142. The plurality of third channels are parallel to each other. The plurality of third electrochromic bodies 142 are parallel to each other. The extending directions of the third channels intersect the extending directions of the first channel and the second channel respectively. The extending direction of the third electrochromic body 142 intersects the extending direction of the second electrochromic body 141 and also intersects the extending direction of the first electrochromic body 131. The first end of the third electrochromic body 142 is electrically connected to the first electrode 111, and the second end of the third electrochromic body 142 is electrically connected to the first independent electrode 123. Wherein, the second visual range adjustment unit 140 being in the light-shielding state includes the third electrochromic body 142 being in the light-shielding state. When the third electrochromic body 142 is in the light-shielding state, the visual range of the visual range adjustable device 100 is the second sub-range.

[0080] The light-transmitting state of the third electrochromic body 142 includes a light-shielding state and a light-transmitting state. When the third electrochromic body 142 is in the light-shielding state, the second visual range adjustment unit 140 is in the light-shielding state; when the third electrochromic body 142 is in the light-transmitting state, the second visual range adjustment unit 140 is in the visible state.

[0081] In a specific embodiment of this implementation, as Figure 3 shown, the first electrochromic body 131, the second electrochromic body 141, and the third electrochromic body 142 partially intersect with each other, and the intersection area contacts the first electrode 111. Along the direction perpendicular to the arrangement of the plurality of first electrochromic bodies 131 and along the direction perpendicular to the stacking direction of the first electrode layer 110 and the second electrode layer 120, the projection of the second electrochromic body 141 except the part intersecting with the first electrochromic body 131 does not overlap with the projection of the third electrochromic body 142. At the same time, along the direction perpendicular to the arrangement of the plurality of first electrochromic bodies 131 and along the direction perpendicular to the stacking direction of the first electrode layer 110 and the second electrode layer 120, the projection of the third electrochromic body 142 except the part intersecting with the first electrochromic body 131 does not overlap with the projection of the second electrochromic body 141.

[0082] In a specific embodiment of this implementation, as Figure 4aAs shown, along the direction perpendicular to the arrangement of several first electrochromic bodies 131 and along the direction perpendicular to the stacking direction of the first electrode layer 110 and the second electrode layer 120, the projections of the second electrochromic body 141 and the third electrochromic body 142 do not overlap.

[0083] In this implementation, the first electrochromic body 131, the second electrochromic body 141, and the third electrochromic body 142 share the first electrode 111. Therefore, the first electrode 111 can be Figure 4a as shown, with a full-surface structure and without the need for patterning, which simplifies the process flow and reduces the production cost. However, it should be noted that considering the factor of saving wiring materials, the first electrode 111 can still be Figure 3 or Figure 4b as shown for patterning. Since the first electrode 111 is shared, after patterning, the space of the hollow part of the first electrode 111 is large, which reduces the patterning accuracy and is also beneficial to cost reduction.

[0084] As Figure 1 , Figure 3 or Figure 4a shown, in a possible implementation, the orthographic projection of the second end of the second electrochromic body 141 on the first substrate 101 is in the first direction of the first end of the second electrochromic body 141, and the orthographic projection of the second end of the third electrochromic body 142 on the first substrate 101 is in the second direction of the first end of the third electrochromic body 142, and the first direction is opposite to the second direction.

[0085] In this implementation, relative to the first electrochromic body 131, the tilting directions of the second electrochromic body 141 and the third electrochromic body 142 are opposite, so that the first sub-range and the second sub-range are respectively the left and right side viewing ranges, thereby realizing the adjustment of the visible range when moving on different sides, and further improving the experience.

[0086] As Figure 5 shown, in a possible implementation, the orthographic projection of the second end of the second electrochromic body 141 on the first substrate 101 is in the first direction of the first end of the second electrochromic body 141, and the orthographic projection of the second end of the third electrochromic body 142 on the first substrate 101 is in the second direction of the first end of the third electrochromic body 142, and the first direction is the same as the second direction. The second electrochromic body 141 and the third electrochromic body 142 do not intersect and there is no overlapping area between them. The second channel and the third channel in the insulating layer are disconnected and not connected.

[0087] In this implementation manner, the first direction is the same as the second direction, which means that the adjustment of different visible ranges is achieved from the left or right perspective. On the one hand, it can better play the role of anti-peeping, and on the other hand, it can achieve the intelligent adjustment of the viewing range of the device owner, improving the experience.

[0088] Based on the foregoing embodiments, in a possible implementation manner, when the visible range adjustable device 100 is in the first state and the target recognition feature of the target user is within the first range, the first visible range adjustment unit 130 is in a light-shielding state, and the second visible range adjustment unit 140 is in a visible state, including:

[0089] As Figure 2a shown, when the visible range adjustable device 100 is in the first state and the target recognition feature of the target user is within the first range, the first electrochromic body 131 is in a light-shielding state, the second electrochromic body 141 is in a light-transmitting state, and the third electrochromic body 142 is in a light-transmitting state.

[0090] Combined with Figure 2b and Figure 2c , the first region A1 includes a first sub-region β11 and a second sub-region β21, where the first sub-region β11 is located in the first sub-range β1 and the second sub-region β21 is located in the second sub-range β2. When the visible range adjustable device 100 is in the first state and the target recognition feature of the target user is within the first region, the second visible range adjustment unit 140 is in a light-shielding state, and the first visible range adjustment unit 130 is in a visible state, including:

[0091] As Figure 2b shown, when the visible range adjustable device 100 is in the first state and the target recognition feature of the target user is within the first sub-region β11, the second electrochromic body 141 is in a light-shielding state, the first electrochromic body 131 is in a light-transmitting state, and the third electrochromic body 142 is in a light-transmitting state;

[0092] As Figure 2c shown, when the visible range adjustable device 100 is in the first state and the target recognition feature of the target user is within the second sub-region β21, the third electrochromic body 142 is in a light-shielding state, the first electrochromic body 131 is in a light-transmitting state, and the second electrochromic body 141 is in a light-transmitting state.

[0093] In a possible implementation manner, the first sub-range β1 and the second sub-range β2 do not overlap. In a possible implementation manner, when the visible range adjustable device 100 is in the first state, the visible range of the visible range adjustable device 100 changes with the change of the region where the target recognition feature of the target user is located, including:

[0094] When the visible range adjustable device 100 is in the first state and the target recognition feature of the target user is in the first sub-range β1, the second electrochromic body 141 is in a light-shielding state, and the first electrochromic body 131 is in a light-transmitting state and the third electrochromic body 142 is in a light-transmitting state;

[0095] When the visible range adjustable device 100 is in the first state and the target recognition feature of the target user is in the second region, the first electrochromic body 131 is in a light-shielding state, the second electrochromic body 141 is in a light-transmitting state, and the third electrochromic body 142 is in a light-transmitting state. In the present implementation manner, the second region is located outside the first sub-range and within the first range.

[0096] When the visible range adjustable device 100 is in the first state and the target recognition feature of the target user is in the second sub-region β21, the third electrochromic body 142 is in a light-shielding state, and the first electrochromic body 131 is in a light-transmitting state and the second electrochromic body 141 is in a light-transmitting state.

[0097] In a possible implementation manner, the first sub-range β1 and the second sub-range β2 do not overlap. In a possible implementation manner, when the visible range adjustable device 100 is in the first state, the visible range of the visible range adjustable device 100 changes with the change of the region where the target recognition feature of the target user is located, including:

[0098] When the visible range adjustable device 100 is in the first state and the target recognition feature of the target user is in the first sub-region β11, the second electrochromic body 141 is in a light-shielding state, and the first electrochromic body 131 is in a light-transmitting state and the third electrochromic body 142 is in a light-transmitting state;

[0099] When the visible range adjustable device 100 is in the first state and the target recognition feature of the target user is in the second region, the first electrochromic body 131 is in a light-shielding state, the second electrochromic body 141 is in a light-transmitting state, and the third electrochromic body 142 is in a light-transmitting state. In the present implementation manner, the second region is located outside the second sub-range and within the first range.

[0100] When the visible range adjustable device 100 is in the first state and the target recognition feature of the target user is in the second sub-range β2, the third electrochromic body 142 is in a light-shielding state, and the first electrochromic body 131 is in a light-transmitting state and the second electrochromic body 141 is in a light-transmitting state.

[0101] With Figure 5For example, in a possible implementation, the first sub-range overlaps with the second sub-range. The first sub-range includes a third region, and the third region is located outside the first region. The second sub-range includes a fourth region, and the fourth region is located outside the first sub-range and outside the first region.

[0102] In a possible implementation, when the visible range adjustable device 100 is in the first state, the visible range of the visible range adjustable device 100 changes with the change of the region where the target recognition feature of the target user is located, including:

[0103] When the visible range adjustable device 100 is in the first state and the target recognition feature of the target user is within the first range, the first electrochromic body 131 is in a light-shielding state, the second electrochromic body 141 is in a light-transmitting state, and the third electrochromic body 142 is in a light-transmitting state.

[0104] When the visible range adjustable device 100 is in the first state and the target recognition feature of the target user is within the third region, the second electrochromic body 141 is in a light-shielding state, the first electrochromic body 131 is in a light-transmitting state, and the third electrochromic body 142 is in a light-transmitting state.

[0105] When the visible range adjustable device 100 is in the first state and the target recognition feature of the target user is within the fourth region, the third electrochromic body 142 is in a light-shielding state, the first electrochromic body 131 is in a light-transmitting state, and the second electrochromic body 141 is in a light-transmitting state.

[0106] In a possible implementation, the overlapping region of the first range and the second range includes a first overlapping region, and the first sub-range includes the first overlapping region; the first region includes a first sub-region, and the first sub-region is located within the first sub-range. When the visible range adjustable device 100 is in the first state, the visible range of the visible range adjustable device 100 changes with the change of the region where the target recognition feature of the target user is located, including:

[0107] When the visible range adjustable device 100 is in the first state and the target recognition feature of the target user is within the first overlapping region, the states of the first visible range adjustment unit 130 and the second visible range adjustment unit 140 are the same as the corresponding states when the target recognition feature of the target user is within the previous region. The previous region refers to the region where the target recognition feature of the target user was located when the target recognition feature was collected last time.

[0108] That is, when the visible range adjustable device 100 is in the first state and the target recognition feature of the target user is in the first overlapping area, the states of the first electrochromic body 131, the second electrochromic body 141, and the third electrochromic body 142 are the same as the corresponding states when the target recognition feature of the target user is in the prior area.

[0109] For example, when the target recognition feature of the target user is in the second area (outside the first sub-range and within the first range), the first visible adjustment part is in a light-shielding state, and the second visible range adjustment part 140 is in a visible state (at this time, the second electrochromic body 141 is in a visible state, and the third electrochromic body 142 is in a visible state). When the target recognition feature of the target user moves from the second area to the first overlapping area, the states of the first visible range adjustment part 130 and the second visible adjustment part do not change, that is, the first visible adjustment part is in a light-shielding state, and the second visible range adjustment part 140 is in a visible state. When the target recognition feature of the target user moves from the first overlapping area to the first sub-area, the states of the first visible range adjustment part 130 and the second visible adjustment part change, that is, the first visible adjustment part is in a visible state (at this time, the first electrochromic body 131 is in a light-transmitting state), and the second visible range adjustment part 140 is in a light-shielding state (at this time, the second electrochromic body 141 is in a light-shielding state and the third electrochromic body 142 is in a light-transmitting state). When the target recognition feature of the target user moves from the first sub-area to the first overlapping area, the states of the first visible range adjustment part 130 and the second visible adjustment part do not change (that is, the states of the first electrochromic body 131, the second electrochromic body 141, and the third electrochromic body do not change), that is, the first visible adjustment part is in a visible state (that is, the first electrochromic body 131 is in a light-transmitting state), and the second visible range adjustment part 140 is in a light-shielding state (that is, the second electrochromic body 141 is in a light-shielding state and the third electrochromic body 142 is in a light-transmitting state). This state switching mechanism avoids unnecessary state changes of the first visible range adjustment part 130 and the second visible range adjustment part, thereby simplifying the complexity of control and facilitating cost reduction.

[0110] Such as Figure 6As shown, in a possible implementation, the second range includes: a first side view range. The second visual range adjustment unit 140 includes: a third electrode 122, a fourth electrode 113, and a plurality of second electrochromic bodies 141. The third electrode 122 is located in the second electrode layer 120 and is electrically insulated from the second electrode 121. The fourth electrode 113 is located in the first electrode layer 110 and is electrically insulated from the first electrode 111. The insulating layer further includes a plurality of second channels. The number of second channels is equal to the number of second electrochromic bodies 141. One second electrochromic body 141 is disposed in each second channel. The plurality of second channels are parallel to each other. The plurality of second electrochromic bodies 141 are parallel to each other. The extending direction of the second electrochromic body 141 intersects the extending direction of the first electrochromic body 131. The first end of the second electrochromic body 141 is electrically connected to the fourth electrode 113, and the second end of the second electrochromic body 141 is electrically connected to the third electrode 122. Wherein, the second visual range adjustment unit 140 being in a light-shielding state includes the second electrochromic body 141 being in a light-shielding state. When the second electrochromic body 141 is in a light-shielding state, the visual range of the visual range adjustable device 100 is the first side view range.

[0111] The light-transmitting state of the second electrochromic body 141 includes a light-shielding state and a light-transmitting state. When the second electrochromic body 141 is in a light-shielding state, the second visual range adjustment unit 140 is in a light-shielding state; when the second electrochromic body 141 is in a light-transmitting state, the second visual range adjustment unit 140 is in a visible state.

[0112] In this implementation, the second electrochromic body 141 and the first electrochromic body 131 use their respective independent electrodes, which is conducive to control. Moreover, this design realizes the independence of the electrodes. Therefore, when one electrode fails, the other electrodes are not affected, increasing the fault resistance of the overall adjustment component.

[0113] Such as Figure 1As shown in FIG. 5 or FIG. 6, in a possible implementation, the second range includes: a second side view range. The second visual range adjusting unit 140 includes: a first independent electrode 123, a second independent electrode 112, and a plurality of third electrochromic bodies 142. The first independent electrode 123 is located in the second electrode layer 120 and is electrically insulated from the second electrode 121 and the third electrode 122 respectively. The second independent electrode 112 is located in the first electrode layer 110 and is electrically insulated from the first electrode 111. The insulating layer includes a plurality of third channels. The number of the third channels is equal to the number of the third electrochromic bodies 142. Each third channel includes a third electrochromic body 142. The plurality of third channels are parallel to each other. The plurality of third electrochromic bodies 142 are parallel to each other. The extending directions of the third channels intersect with the extending direction of the first channel and the extending direction of the second channel respectively. The plurality of third electrochromic bodies 142 are parallel to each other. The extending direction of the third electrochromic body 142 intersects with the extending direction of the second electrochromic body 141 and intersects with the extending direction of the first electrochromic body 131. The first end of the third electrochromic body 142 is electrically connected to the second independent electrode 112, and the second end of the third electrochromic body 142 is electrically connected to the first independent electrode 123. Wherein, the second visual range adjusting unit 140 being in a light-shielding state includes the third electrochromic body 142 being in a light-shielding state. When the third electrochromic body 142 is in the light-shielding state, the visual range of the visual range adjustable device 100 is the second side view range.

[0114] The light-transmitting state of the third electrochromic body 142 includes a light-shielding state and a light-transmitting state. When the third electrochromic body 142 is in the light-shielding state, the second visual range adjusting unit 140 is in the light-shielding state; when the third electrochromic body 142 is in the light-transmitting state, the second visual range adjusting unit 140 is in the visible state.

[0115] In this implementation, the third electrochromic body 142 independently uses the first independent electrode 123 and the second independent electrode 112, thereby realizing the independent control of the third electrochromic body.

[0116] As Figure 1 or Figure 6 shown, in a possible implementation, the second electrochromic body 141 intersects with the third electrochromic body 142, and the intersecting part of the second electrochromic body 141 and the third electrochromic body is located between the first end and the second end of the second electrochromic body 141.

[0117] In this implementation, the intersection of the second electrochromic body 141 and the third electrochromic body 142 is beneficial to saving the layout space and reducing the thickness of the visual range adjustable device 100.

[0118] As Figure 6As shown, in a possible implementation, the third electrode 122 is located in the third direction of the second independent electrode 112, and the first independent electrode 123 is located in the third direction of the fourth electrode 113. The third direction is perpendicular to the first substrate 101.

[0119] In this implementation, the electrode distribution of the first electrode layer 110 and the electrode distribution pattern of the second electrode layer 120 are the same. Therefore, the first electrode layer 110 and the second electrode layer 120 use the same mask to implement the patterning process, which helps to reduce the production cost.

[0120] In a possible implementation, the visible range adjustable device 100 further includes a second state. The second state can be a shared state, that is, a non-privacy state. When the visible range adjustable device 100 is in the second state, both the first visible range adjustment unit 130 and the second visible range adjustment unit 140 are in a visible state.

[0121] When the visible range adjustable device 100 is in the second state, no privacy protection is performed. The visible range adjustable device 100 includes a first state and a second state, so that the visible range adjustable device 100 has both a privacy protection function and a sharing function, increasing the practicality.

[0122] As Figure 5 or Figure 7a Or Figure 7b As shown, in a possible implementation, the insulating layer further includes a fourth channel and a fifth channel. The fourth channel intersects with the second channel and the third channel respectively, and the fifth channel intersects with the second channel and the third channel respectively. The second visible range adjustment unit 140 further includes a third independent electrode 124, a fourth independent electrode 114, a fifth independent electrode 125, a sixth independent electrode 115, a plurality of fourth electrochromic bodies 143 and a plurality of fifth electrochromic bodies 144. The fourth electrochromic bodies 143 are located in the fourth channel, and the fourth electrochromic bodies 143 correspond to the fourth channel one by one. The fifth electrochromic bodies 144 are located in the fifth channel, and the fifth electrochromic bodies 144 correspond to the fifth channel one by one. The third independent electrode 124 and the fifth independent electrode 125 are respectively located in the first electrode layer 110, and the fourth independent electrode 114 and the sixth independent electrode 115 are respectively located in the second electrode layer 120. Two ends of the fourth electrochromic bodies 143 are correspondingly electrically connected to the third independent electrode 124 and the fourth independent electrode 114. Two ends of the fifth electrochromic bodies 144 are correspondingly electrically connected to the fifth independent electrode 125 and the sixth independent electrode 115. The working principle and process of the fifth electrochromic bodies 144 and the sixth electrochromic bodies can refer to the third electrochromic body 142 or the second electrochromic body 141, which will not be elaborated here.

[0123] In this implementation manner, adding the fourth electrochromic body 143 and the sixth electrochromic body can increase the adjustable precision of the anti-peeping angle and the adjustable precision of the visible range.

[0124] In this implementation manner, Figure 5 each electrochromic body in Figure 5 has its own independent electrode. At the same time Figure 5 the electrode pattern of the first electrode layer in Figure 7a is inconsistent with the electrode pattern of the second electrode layer. It should be noted that, based on the anti-peeping angle requirement or design, the Figure 7a electrode patterns of the first electrode layer and the second electrode layer in Figure 7b can be made into the same pattern to meet the requirement of cost reduction. It can be only used as the same pattern. Therefore, the patterning process of the first electrode layer and the patterning process of the first electrode layer can use the same mask, thereby reducing the production cost. Figure 7b the first electrochromic body and the second electrochromic body in Figure 7a share the first electrode, and in this implementation manner Figure 7b the electrode pattern of the first electrode layer in Figure 7c is inconsistent with the electrode pattern of the second electrode layer.

[0125] It should be noted that when the first visible range adjustment unit 130 provided in the embodiment of the present application is in the visible state, it means that all the electrochromic bodies included therein are in the light-transmitting state; when the second visible range adjustment unit 140 is in the visible state, it means that all the electrochromic bodies included therein are in the light-transmitting state. When the first visible range adjustment unit 130 is in the light-shielding state, it means that all the electrochromic bodies included therein are in the light-shielding state; when the second visible range adjustment unit 140 is in the light-shielding state, it means that a certain type of electrochromic body (such as the second electrochromic body 141 or the third electrochromic body 142) among all the electrochromic bodies included therein is in the light-shielding state, and the remaining types of electrochromic bodies are in the light-transmitting state.

[0126] The working principle of the visible range adjustable device provided by the embodiment of the present application is as Figures 8 to 12 . Among them, Figures 8 to 10 it is for the case including the first electrochromic body, the second electrochromic body, and the third electrochromic body. Figure 8 Corresponding to Figure 1 and Figure 9 corresponding to Figure 3or Figure 4a correspondingly Figure 10 with Figure 6 correspondingly Figure 11 with Figure 7a correspondingly Figure 12 with Figure 7b or Figure 7c correspondingly Figure 13 with Figure 5 correspondingly

[0127] Taking Figure 10 as an example, with Figure 6 time-sharing control can be performed by controlling the switches of the branches where the first electrochromic body, the second electrochromic body, and the third electrochromic body are located, so as to realize the adjustment of the visible range. For example, when the visible range adjustable device 100 is in the first state and the target recognition feature of the target user is in the first range, the switch of the branch where the first electrochromic body is located is turned on, and the first electrochromic body 131 is in the light-shielding state. The switches of the branches where the second electrochromic body and the third electrochromic body are located are turned off, the second electrochromic body 141 is in the light-transmitting state, and the third electrochromic body 142 is in the light-transmitting state.

[0128] When the visible range adjustable device 100 is in the first state and the target recognition feature of the target user is in the first sub-region β11, the switch of the branch where the second electrochromic body 141 is located is turned on, and the second electrochromic body 141 is in the light-shielding state. The switches of the branches where the first electrochromic body 131 and the third electrochromic body are located are turned off respectively, the first electrochromic body 131 is in the light-transmitting state, and the third electrochromic body 142 is in the light-transmitting state.

[0129] When the visible range adjustable device 100 is in the first state and the target recognition feature of the target user is in the second sub-region β21, the switch of the branch where the third electrochromic body 142 is located is turned on, and the third electrochromic body 142 is in the light-shielding state. The switches of the branches where the first electrochromic body 131 and the second electrochromic body 141 are located are turned off, and the first electrochromic body 131 is in the light-transmitting state and the second electrochromic body 141 is in the light-transmitting state.

[0130] The embodiment of the present application also provides a driving method for the visible range adjustable device 100, including:

[0131] S100, determining the working state of the visible range adjustable device 100.

[0132] The operating state of the visible range adjustable device 100 can be determined by a flag bit or flag information. The operating state of the visible range adjustable device 100 includes a first state and a second state. When the determination result of the operating state of the visible range adjustable device 100 is the first state, step S200 is executed. When the determination result of the operating state of the visible range adjustable device 100 is the second state, step S400 is executed.

[0133] S200. Based on the visible range adjustable device 100 being in the first state, obtain the target recognition features of the user.

[0134] When the visible range adjustable device 100 is in the first state, it means it is in the anti-peeping state. In the anti-peeping state, it is necessary to detect the area where the target recognition features of the target user are located in order to adjust the visible range. Therefore, it is necessary to obtain the target recognition features of the user, such as obtaining the facial features and / or eye features of the user, etc.

[0135] After obtaining the target recognition features of the user, they will be recognized or judged to determine whether the user is the target user. For example, to recognize whether the user includes the owner or an individual or group permitted by the owner. When the user includes the target user, step S300 is executed. It should be noted that the user is only a term and does not refer to the individual or group using the device. The user can be all individuals or groups within the range of recognition feature collection; for example, by acquiring the target recognition features of the user through image acquisition, then the user can be all individuals within the image acquisition range. When the user does not include the target user, step S500 is executed.
