In order to more clearly illustrate the invention, the invention is further described below with reference to preferred embodiments and the accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. It is to be understood by persons skilled in the art that the following detailed description is illustrative and not restrictive, and is not to be taken as limiting the scope of the invention.
As shown in fig. 1, an embodiment of the present invention provides a display device, including a controller (not shown in the figure), a display panel 30, and a photonic crystal 10 with an adjustable forbidden band width, wherein the photonic crystal 10, located on a light-emitting side of the display panel 30, includes a first electrode 16 and a second electrode 11 that are oppositely disposed, and a photonic structure located between the first electrode 16 and the second electrode 11; the controller is configured to control voltages applied to the first electrode 16 and the second electrode 11 of the photonic crystal 10 in response to an external signal, such that the photonic structure changes a forbidden band width in response to the applied voltages to adjust a color of light emitted by the display panel 30.
In the present embodiment, the photonic crystal refers to an artificial periodic dielectric structure having photonic band gap characteristics. A photonic band gap is a periodic structure in which a wave in a certain frequency range cannot propagate, i.e., the structure itself has a "forbidden band". The photonic crystal with the adjustable forbidden band width refers to a photonic crystal of which the position and the width of the photonic band gap can be changed along with the change of the external environment. In this embodiment, the photonic crystal 10 includes a first electrode 16, a photonic structure and a second electrode 11 arranged in a stack, i.e., the photonic structure changes the optical properties of the photonic crystal in response to loading at the first and second electrodes. Meanwhile, the photonic crystal 10 is arranged on the light-emitting side of the display panel 30, light emitted by the display panel 30 enters the photonic crystal 10 through the transparent glass substrate 20 for connecting the display panel 30 and the photonic crystal 10, and the color of the light emitted by the display panel is adjusted by blocking the light through the photonic crystal or by part of the color of the light, so that the problem of thickness and cost in the prior art is solved, and the display panel has wide application value.
In an optional embodiment, further comprising a configuration table, the controller is configured to: inquiring the configuration table in response to a first external signal, determining a first light allowable band and a first voltage and a second voltage corresponding to the first light allowable band according to a first display mode corresponding to the first external signal, and respectively applying the first voltage and the second voltage to the first electrode and the second electrode; or responding to a second external signal to query the configuration table, determining a second light allowable wave band and a third voltage and a fourth voltage corresponding to the second light allowable wave band according to a second display mode corresponding to the second external signal, and respectively loading the third voltage and the fourth voltage to the first electrode and the second electrode; or in response to a third external signal, querying the configuration table, determining a third light-allowed band and a fifth voltage and a sixth voltage corresponding to the third light-allowed band according to a third display mode corresponding to the third external signal, and applying the fifth voltage and the sixth voltage to the first electrode and the second electrode, respectively; or responding to a fourth external signal to query the configuration table, and stopping applying the voltage to the first electrode and the second electrode according to a fourth display mode corresponding to the fourth signal.
In this embodiment, the configuration table is stored in the controller or other memory, the configuration table includes a display mode, a light-allowed wavelength band and two corresponding voltage values, and the controller reads the configuration table to obtain the display mode, the light-allowed wavelength band and the two corresponding voltage values corresponding to the received external signal. Wherein the display mode is a color tone of light emitted by the display panel, and the embodiment includes a warm yellow color tone, a cool white color tone and a positive white color tone. Corresponding to the display mode is a light-allowed band that allows light to pass: for example, the warm yellow hue is warm yellow light with a color temperature of 4500-5500 k, and the corresponding wave band is 490-700 nm; for example, the cold white color tone is 6500-7500K cold white light, the corresponding wave band is 460-600 nm, for example, the positive white color tone is 5500-6500K natural light, and the corresponding wave band is 380-700 nm. Meanwhile, the two voltage values respectively correspond to voltages loaded on the first electrode and the second electrode of the photonic crystal.
Specifically, the first external signal corresponds to a first display mode (warm yellow tone) corresponding to a first light allowable band (490nm to 700nm) and first and second voltages corresponding to the first light allowable band; the second external signal corresponds to a second display mode (a cold white tone) corresponding to a second light allowable band (460nm to 600nm) and third and fourth voltages corresponding to the second light allowable band; the third external signal corresponds to a third display mode (positive white tone) corresponding to a third light allowable band (380nm to 700nm) and fifth and sixth voltages corresponding to the third light allowable band.
It is worth mentioning that the present embodiment also provides a common color tone, that is, the color tone of the light emitted by the display panel is not changed, in other words, the controller does not apply a voltage to the first electrode and the second electrode of the photonic crystal, and the light emitted by the display device is the light emitted by the display panel. Specifically, the fourth signal corresponds to a fourth display mode (ordinary tone), and no voltage is applied to the first electrode and the second electrode of the photonic crystal.
In this embodiment, the controller queries, according to the configuration table, a display mode matched with an external signal from the configuration table in response to the external signal, determines a wavelength band allowing light to pass through according to the display mode, and adjusts the forbidden band width of the photonic crystal to a voltage required to be applied to the first electrode and the second electrode for the forbidden band width suitable for the wavelength band, and then the controller applies the voltage queried in the configuration table to the first electrode and the second electrode of the photonic crystal, thereby adjusting the color of light emitted by the display panel in response to the external signal.
In an alternative embodiment, as shown in fig. 1, the photonic structure includes an electroactive layer 15, an electrolyte 17, and a plurality of microspheres 14 uniformly distributed in the electroactive layer 15, wherein the electrolyte 17 dissolves in or precipitates out of the electroactive layer 15 in response to voltages applied to the first electrode 16 and the second electrode 11 so as to change a spatial density of the plurality of microspheres 14 to change a forbidden bandwidth of the photonic crystal 10.
In this embodiment, as shown in fig. 2, when no voltage is applied to the first electrode and the second electrode of the photonic crystal, the spatial distribution of the microspheres in the photonic crystal is shown in the left diagram. When the voltage difference loaded on the first electrode and the second electrode of the photonic crystal is E1, an electric field is formed, part of electrolyte is dissolved in the electroactive layer, the space distribution of a plurality of microspheres of the photonic crystal is shown in a middle diagram, the space density of the microspheres is increased, and the forbidden bandwidth of the photonic crystal is changed. When the voltage difference loaded on the first electrode and the second electrode of the photonic crystal is further increased to E2, an electric field is formed, more electrolyte is dissolved into the electroactive layer, the spatial distribution of a plurality of microspheres of the photonic crystal is shown in the right diagram, the spatial density of the microspheres is further increased, and the forbidden bandwidth of the photonic crystal is changed accordingly. At this time, the voltage applied to the first electrode and the second electrode of the photonic crystal is cut off, that is, the voltage is not applied to the first electrode and the second electrode, so that no electric field exists between the first electrode and the second electrode, the electrolyte is separated out from the electroactive layer, the spatial distribution of the microspheres of the photonic crystal is restored to be shown in the left figure, and the forbidden bandwidth of the photonic crystal is restored to be in an initial state. The photonic structure adopted in this embodiment changes the lattice parameter of the photonic crystal in the electric field formed by the voltages applied to the first electrode and the second electrode, and realizes the adjustment of the weight ratio of the color component of the light emitted by the display panel, thereby adjusting the color of the light.
Specifically, in this embodiment, the first electrode and the second electrode are indium tin oxide, so as to ensure the overall transmittance in the normal display mode. The electrolyte is organic acid salt or inorganic acid salt, and does not react with other layers when the first electrode and the second electrode are loaded with voltage to form an electric field. The first packaging layer and the second packaging layer are made of epoxy resin. The electroactive layer comprises a plurality of microspheres, which are polystyrene microspheres with a high surface charge content, which are core components of photonic crystals, including both multi-site Opal (Opal) type or Inverse Opal (Inverse Opal) type. The microstructure of the opal is face-centered cubic, is a three-dimensional photonic crystal, can generate selective Bragg reflection, and can present different colors when observed from different angles; inverse opals are porous structures formed by filling certain electrically active materials in the interstices of opal crystals and then removing the raw material of the opal crystals by calcination, dissolution or chemical etching.
It should be noted that, the present application does not limit the specific structure of the photonic crystal controlled in response to the electric field, and those skilled in the art should select an appropriate photonic structure according to the actual application requirement to implement the design rule of changing the forbidden band width under the control of the electric field, and details are not repeated herein.

In this embodiment, when no voltage is applied to the first electrode and the second electrode of the photonic crystal, the electrolyte is located in the accommodating space; when voltage is loaded on the first electrode and the second electrode of the photonic crystal, part of electrolyte is dissolved into the electroactive layer, and the spatial density of the microspheres is increased; when the first electrode and the second electrode of the photonic crystal are disconnected with the loaded voltage, part of electrolyte dissolved into the electroactive layer is separated out from the electroactive layer, the space density of the microspheres is reduced, and the photonic crystal is restored to the initial state.
In an optional embodiment, the display panel is an electroluminescent display panel, and the display panel includes a substrate, and a driving circuit layer, an electroluminescent device layer, and an encapsulation layer sequentially formed in a direction away from the substrate.
