The application is further described below with reference to the drawings and alternative embodiments.
As shown in fig. 1, the embodiment of the application discloses a display device, wherein the display device 10 includes a driving circuit 300 and a display panel 100, the driving circuit 300 drives a light emitting unit 180 in the display panel 100, that is, controls the display panel 100 to emit light and display images, the driving circuit 300 also controls an electrode assembly 140 in the display panel 100, and controls the electrode assembly 140 to be powered off or powered on according to a user requirement, so as to realize switching between a sharing mode and a peep-proof mode of the display panel 100. The display panel 100 is a liquid crystal panel, and the following specific embodiments are referred to for the detailed design of the display panel 100.
As shown in fig. 2 and 3, as one implementation of the electrode assembly in the embodiment of the present application, fig. 2 is a schematic view of the electrode assembly in the display panel when not energized, and fig. 3 is a schematic view of the electrode assembly in the display panel when energized. As an embodiment of the present application, the display panel 100 includes a first substrate 110 and a second substrate 120 that are disposed opposite to each other, and a liquid crystal cell 190 disposed between the first substrate 110 and the second substrate 120, where a plurality of light emitting units 180 are disposed on the first substrate 110 or the second substrate 120 and are distributed at intervals, the first substrate 110 is a color film substrate or an array substrate, and the second substrate 120 is a corresponding array substrate or a color film substrate; the light emitting unit 180 may be disposed on the color film substrate, or may be disposed on the array substrate by COA (Color Filter On Array, color filter on array substrate) technology.
The display panel 100 further includes a support column 130, an electrode assembly 140, and magnetic light shielding particles 150, where the support column 130 is made of a transparent material, one end of the support column 130 is connected to the first substrate 110, and the other end of the support column 130 faces the second substrate 120, and may be in contact with the second substrate 120 or may have a gap with the second substrate; also, the support columns 130 are disposed between adjacent light emitting units 180. The electrode assemblies 140 are arranged in one-to-one correspondence with the support columns 130; the magnetic shading particles 150 are arranged in the liquid crystal box 190 and distributed in the area corresponding to the support columns 130; the side surface of the support column 130 is an inclined surface, and an included angle between the side surface of the support column 130 and the first substrate 110 is an acute angle; when the electrode assembly 140 is energized, the electrode assembly 140 generates a magnetic field perpendicular to the first substrate 110, and the magnetic shielding particles 150 are attracted to the surface of the support columns 130 by the magnetic field.
According to the embodiment of the application, the support columns 130, the electrode assemblies 140 and the magnetic shading particles 150 are arranged in the display panel 100, when the display panel 100 needs to be switched to the peep-proof state, the electrode assemblies 140 are electrified, so that the electrode assemblies 140 generate a magnetic field, the magnetic shading particles 150 move towards the support columns 130 under the action of the magnetic field because the magnetic shading particles 150 are magnetic and light-proof, and the side surfaces of the support columns 130 are inclined surfaces, so that the magnetic shading particles 150 can be adsorbed on the surfaces of the support columns 130 under the action of the magnetic field, and light emitted by the light emitting units 180 cannot penetrate through the support columns 130, so that the peep-proof effect is realized; when the display panel 100 needs to be switched to the sharing mode, the electrode assembly 140 is powered off, and the electrode assembly 140 cannot generate a magnetic field, the magnetic shielding particles 150 are dispersed in the liquid crystal cell 190 and are not attached to the surface of the support column 130, and the light emitted by the light emitting unit 180 can pass through the support column 130, so as to achieve the display sharing effect. Moreover, since the additional support columns 130, the electrode assemblies 140, and the magnetic light shielding particles 150 are disposed within the display panel 100, an increase in thickness of the display panel 100 is not caused.
In this embodiment, the electrode assembly 140 is configured by a pair of opposite electrodes, and the electrode assembly 140 is configured by a first electrode 141 and a second electrode 142, wherein the first electrode 141 is disposed on a side of the first substrate 110 facing the second substrate 120, and the second electrode 142 is disposed on a side of the second substrate 120 facing the first substrate 110 and is disposed opposite to the first electrode 141.
When the first electrode 141 and the second electrode 142 are energized, a magnetic field is generated between the first electrode 141 and the second electrode 142, and the magnetic shielding particles 150 move toward the first substrate 110 under the action of the magnetic field; because the support column 130 is in the range of the magnetic field, the magnetic shading particles 150 are finally attached to the surface of the support column 130, which is equivalent to forming a shading layer on the surface of the support column 130, so that the light emitted to the side of the light emitting unit 180 is blocked, and the peep-proof effect is achieved.
Specifically, the first electrode 141 and the second electrode 142 may both adopt a planar coil structure, may both be an electromagnet, an electromagnetic plate, or may both be an energizing coil, or one of them is an electromagnet, and the other is an energizing coil, and when energized, the two generate opposite electric properties to form a magnetic field, and the magnetism of the magnetic shielding particles 150 is opposite to that generated by energizing the first electrode 141, so that when energizing the first electrode 141 and the second electrode 142, the magnetic shielding particles 150 can move in the direction of the first electrode 141.
Alternatively, when the first electrode 141 and the second electrode 142 are both powered by the power coil, the magnetism is immediately lost when the power coil is powered off, and the magnetic shielding particles 150 immediately fall off from the surface of the support column 130, so that the problem of delay of switching modes does not occur; moreover, the energizing coil is a planar vortex-like structure, the smaller the distance between the wirings is, the stronger the generated magnetic field is, so the magnetic fields generated by the first electrode 141 and the second electrode 142 are gradually enhanced from outside to inside, the acting force applied by the magnetic shading particles 150 is inclined towards the center of the energizing coil, and a larger included angle is generated between the acting force direction and the side surface of the support column 130, so that the acting force of the magnetic shading particles 150 on the side surface of the support baffle column can be increased, and the magnetic shading particles 150 can be stably attached to the side surface of the support column 130 under the action of the magnetic field.
In this embodiment, the side surface of the support column 130 may be designed as an inclined surface, a step shape, or a wavy line shape; the magnetic shielding particles 150 can be attracted to the side surfaces of the support columns 130 by the action of the magnetic field; particularly, when the side surface of the support column 130 is in a step shape, when the first electrode 141 and the second electrode 142 are electrified, the magnetic shading particles 150 are distributed on the inclined surface and the step surface of the support column under the action of a magnetic field, so that the shading area is larger, and the shading effect is better; secondly, the buffer effect can be provided for the magnetic shading particles 150, so that the magnetic shading particles are prevented from crowding towards one place, and the magnetic shading particles 150 are unevenly distributed on the side surfaces of the support columns 130.
In addition, in the present embodiment, all the first electrodes 141 and all the second electrodes 142 in the display panel 100 are connected to the same control line, and the power-on condition of all the first electrodes 141 and all the second electrodes 142 is controlled simultaneously by the control line, so as to realize switching between the peep-proof mode and the sharing mode.
In this embodiment, the orthographic projections of the first electrode 141 and the second electrode 142 on the first substrate 110 overlap, and when the first electrode 141 and the second electrode 142 are energized, the first electrode 141 and the second electrode 142 can generate a uniform magnetic field. Moreover, the front projection area of the support column 130 on the first substrate 110 is smaller than the front projection area of the first electrode 141 on the first substrate 110, at this time, the areas of the first electrode 141 and the second electrode 142 are both larger than the maximum cross-sectional area of the support column 130, so that the whole support column 130 is in the magnetic field range, and the support column 130 is subjected to uniform magnetic field effect everywhere, thereby avoiding the problem of poor shading effect caused by the fact that the support column 130 locally adsorbs less magnetic shading particles 150.
As shown in fig. 4, as one implementation of the electrode assembly in the embodiment of the present application, the difference from the above-described implementation is that the electrode assembly 140 in this embodiment adopts a spiral coil design, that is, the electrode assembly 140 is an electromagnetic coil, and the electromagnetic coil is wound around the corresponding support column 130.
When the electrode assembly 140 is energized, the magnetic shading particles 150 are attached to the surface of the support columns 130 under the action of the magnetic field by controlling the current direction of the spiral coil and thus controlling the magnetic field reversal according to the right-hand spiral rule.
Further, in this embodiment, the side surface of the support column 130 is a step surface, specifically may be a spiral step surface, and the spiral coil is wound along the step surface, so that the spiral coil is wound on the support column 130 without falling off due to gravity or external force.
For the magnetic shading particles 150 in the embodiment of the present application, each magnetic shading particle 150 may have an integral structure, that is, the magnetic shading particle 150 is entirely made of a material having both magnetism and shading, or is made of a mixture of a material having magnetism and a material having shading.
Still alternatively, as shown in fig. 5, the magnetic shading particles 150 adopt a composite layer structure, specifically including a magnetic sphere core 151 and a shading shell 152, wherein the shading shell 152 wraps the magnetic sphere core 151, that is, the interior of the magnetic shading particles 150 is made of a magnetic material, and the outer surface of the magnetic shading particles 150 is made of a shading material.
In order to improve the aggregation of the magnetic shielding particles 150, the embodiment of the application seals the magnetic shielding particles 150 in the liquid crystal cell 190 in a cavity 200.
As a mode of the cavity in the embodiment of the present application, as shown in fig. 6, the display panel 100 includes a first partition wall 171 and a second partition wall 172 made of transparent materials, both ends of the first partition wall 171 are respectively connected to the first substrate 110 and the second substrate 120, both ends of the second partition wall 172 are respectively connected to the first substrate 110 and the second substrate 120, the first partition wall 171 and the second partition wall 172 are disposed between adjacent light emitting units 180 in parallel, and the support columns 130 are disposed between the first partition wall 171 and the second partition wall 172; a cavity 200 is formed between the first partition wall 171 and the second partition wall 172, and the magnetic light shielding particles 150 are disposed in the cavity 200.
In the present embodiment, the cavity 200 is located between the adjacent light emitting units 180, and after the magnetic shading particles 150 are disposed in the cavity 200, the magnetic shading particles 150 will not diffuse into the liquid crystal area corresponding to the light emitting units 180, so that the problem of darkening the display screen caused by light blocking will not occur; further, since the black matrix is disposed between the adjacent light emitting units 180, the cavity 200 and the black matrix are in the same vertical space, and thus neither the peep-proof mode nor the sharing mode may result in a decrease in the aperture ratio of the display panel 100.
In this embodiment, since the support columns 130 are located in the cavity 200, the magnetic light shielding particles 150 are distributed on two sides of the support columns 130, when the electrode assembly 140 is powered on, the magnetic light shielding particles 150 are adsorbed to one surface of the support columns 130 close to the first partition wall 171 and one surface of the support columns 130 close to the second partition wall 172, so that both surfaces of the support columns 130 can be shielded, and the dual shielding design ensures blocking of light, so that the peep preventing effect is better; when the electrode assembly 140 is powered off, the magnetic shielding particles 150 are separated from the both side surfaces of the support column 130 and are scattered in the cavity 200.
Optionally, a gap is provided between the support pillars 130 and the second substrate 120, and the magnetic shielding particles 150 may diffuse from one side of the support pillars 130 to the other side; along with the switching of the peep-proof mode and the sharing mode, if the abnormal condition of the electrode assembly 140 causes the uneven magnetic field, the magnetic shielding particles 150 can be diffused to the side with stronger magnetic field in the support column 130, so that when the electrode assembly 140 is electrified, the magnetic shielding particles 150 can move more rapidly to switch the peep-proof mode. Of course, in the present embodiment, the support columns 130 may directly contact the second substrate 120, so as to prevent the magnetic light shielding particles 150 from diffusing from one side to the other side of the support columns 130.
As a cavity implementation manner in the embodiment of the present application, as shown in fig. 7, the support column 130 abuts against the second substrate 120, the display panel 100 includes a third partition wall 173 made of a transparent material, the third partition wall 173 is disposed between the light emitting unit 180 and one of adjacent support columns 130, a cavity 200 is formed between the third partition wall 173 and the support column 130, and the magnetic light shielding particles 150 are disposed in the cavity 200.
In this embodiment, the number of the partition walls is less, the space of the cavity 200 is smaller, so that the distribution of the magnetic shading particles 150 is more concentrated, and the magnetic shading particles 150 in the cavity 200 only need to be attached to one side of the support column 130 under the action of the magnetic field, so that the aggregation density of the magnetic shading particles 150 on one side of the support column 130 is improved, and the shading effect is improved.
As shown in fig. 8 and 9, the support columns 130 are abutted against the second substrate 120, the support columns 130 on two sides of the light emitting unit 180 adopt two opposite C-shaped or gate-shaped structures, and two sides of the two support columns 130 are mutually attached, so that the support columns 130 on two sides of the light emitting unit 180 are combined to form an annular structure surrounding the light emitting unit 180; a cavity 200 is formed between the support columns 130 at both sides of the light emitting unit 180, and the magnetic shading particles 150 are disposed in the cavity 200.
In this embodiment, the cavity 200 is directly formed by using the support columns 130 on both sides of the light emitting unit 180 without adding additional partition walls, thereby simplifying the structural design. In this case, each light emitting unit 180 is surrounded by an annular support member, and the front projection of the support member on the first substrate 110 may be circular, square, or other shapes. In addition, after the electrode assembly 140 is electrically conductive, since the two sidewalls of the supporting structure are provided between the adjacent two light emitting units 180, which corresponds to two light blocking layers, the peep preventing effect can be greatly ensured.
In addition, for the specific design of the support column 130 in the embodiment of the present application, as shown in fig. 10, the support column 130 may be a whole structure, that is, the support column 130 is a continuous structure surrounding one side, two sides, three sides or four sides of the light emitting unit 180; moreover, when the support column 130 is configured to surround at least two sides of the light emitting unit 180, the electrode assemblies 140 on each side of the light emitting unit 180 can be driven respectively, so that different peep-proof switching modes can be controlled as required, and switching of left-right side peep-proof, upper-lower side peep-proof, three-side peep-proof and four-side peep-proof modes can be realized. Of course, a plurality of support columns 130 may be disposed at one side of the light emitting unit 180, and the plurality of support columns 130 may be arranged at least at two sides.
In addition, the inventive concept of the present application can form a very large number of embodiments, but the application documents are limited in size and cannot be listed one by one, so that on the premise of no conflict, new examples can be formed between the above-described embodiments or between the technical features, and the original technical effects will be enhanced after the embodiments or the technical features are combined.
