Referring to fig. 1, fig. 1 is a schematic structural diagram of a light emitting device 100 according to an embodiment of the present disclosure.
A light emitting device 100 includes a substrate 110, a plurality of light emitting pixel sites 120, and a filter 130. The plurality of light emitting sub-pixels are disposed on the substrate 110. The filter film 130 covers the surface of the at least one light-emitting photon pixel point 120, and is configured to modify the color of the emitted light spectrum of the at least one light-emitting photon pixel point 120, so as to selectively adjust the wavelength range. The filling layer 140 is formed on the substrate 110 and covers the plurality of light-emitting sub-pixels 120, so that the light-emitting device 100 is planarized.
In this embodiment, the filter film 130 can narrow the light spectrum of the light-emitting sub-pixel 120, so that the wavelength range of the light emitted from the filter film 130 is different from the wavelength range of the light incident into the filter film 130, so as to filter the short wavelength range in the light spectrum of the light-emitting sub-pixel 120, and the color coordinate of the light emitted from the light-emitting sub-pixel is adjusted by modifying the light spectrum, thereby changing the color gamut of the light-emitting device 100.
The substrate 110 is used to support a plurality of light emitting sub-pixel points and the filling layer 140, and it can also be used to conduct heat. The substrate 110 may be made of a ceramic material having good insulation properties. The ceramic material can be selected from aluminum oxide (Al)2O3) Magnesium oxide (MgO), aluminum nitride (AlN), Boron Nitride (BN), silicon oxide (SiO)2) Beryllium oxide (BeO), etc. The substrate 110 is located under the light emitting member 100.
The filling layer 140 may be used to planarize the upper side of the light emitting member 100. The filling layer 140 may have a function of suppressing exposure of the light-emitting sub-pixel and the like to moisture or to air. The filling layer 140 may be made of a light-transmissive material. The filling layer 140 may be made of epoxy resin (epoxy) or silicone resin (silicone), silicon nitride (SiN), silicon oxynitride (SiON), or the like.
In this embodiment, the filter film 130 may be a quantum dot material. As shown in fig. 2, the filter film 130 can release light by absorbing the light emitted from the light-emitting sub-pixel 120 covered by the filter film. The wavelength range of the light emitted from the filter film 130 is within the wavelength range of the emission spectrum of the light-emitting sub-pixel 120 covered by the filter film 130, so that the wavelength range of the light emitted from the filter film 130 is within the wavelength range of the emission spectrum of the light-emitting sub-pixel 120The long range is narrower than the wavelength range of the light entering the filter film 130, i.e. the light spectrum of the light emitting sub-pixel 120 is narrowed. The quantum dot material can be CdSe/ZnS quantum dot, CdSe/CdS quantum dot, InAlAs/AlGaAs quantum dot, InP quantum dot, PbSe/PbS quantum dot, ZnGa2S4At least one of Cu/CaS quantum dots, CdTe/CdS/ZnS quantum dots, CuInS quantum dots, carbon quantum dots, graphene quantum dots, pure inorganic or organic inorganic doped perovskite quantum dots and alloy quantum dots. And the quantum dot material can be single-structure quantum dots and core-shell structure quantum dots.
In other embodiments, the filter film 130 can also be a band-stop filter or one of a plurality of dielectric films. As shown in fig. 3, the filter film 130 can prevent light rays in a partial wavelength range within the spectral wavelength range emitted by the light-emitting sub-pixel 120 covered by the filter film 130 from passing through, so that the wavelength range of the light rays emitted from the filter film 130 is narrower than the wavelength range of the light rays incident into the filter film 130, that is, the light-emitting spectrum of the light-emitting sub-pixel 120 is narrowed. The filter film 130 may be a multi-layer dielectric film including a plurality of dielectric layers. Wherein, the refractive indexes of two adjacent dielectric layers are different. The number of dielectric films may be 2, 3, 4, 5 layers … …
In this embodiment, the light emitting color of the light emitting sub-pixel 120 may be one of red, blue, green, purple, magenta, yellow, amber, and other light colors. The light emitting sub-pixel 120 may be a light emitting diode chip or other light emitting unit. The light emitting sub-pixel points 120 may be arranged in an array on the substrate 110. It is understood that in other embodiments, the filter film 130 can cover one or more of the light-emitting sub-pixels 120. The wavelength range adjustment of the light-emitting colors of the plurality of light-emitting sub-pixel points is realized.
In this embodiment, as shown in fig. 4, the light emitting element includes a first light emitting sub-pixel 121, a second light emitting sub-pixel 122 and a third light emitting sub-pixel 123, wherein the first light emitting sub-pixel is used for emitting red light, the second light emitting sub-pixel is used for emitting green light, and the third light emitting sub-pixel is used for emitting blue light; the filter film 130 covers the surface of the second sub-pixel, that is, the light-emitting surface of the led emitting the green light, and the filter film 130 can narrow the light-emitting spectrum of the green sub-pixel 122, so that the wavelength range of the green light emitted from the filter film 130 is different from the wavelength range of the green light emitted into the filter film 130, and the color coordinate of the emitted green light is adjusted by color-modifying the green light spectrum, so that the light-emitting device 100 including the filter film 130 has a different color gamut from the light-emitting device 100 without the filter film 130, that is, the color gamut of the light-emitting device 100 is changed, so that the color gamut of the light-emitting device 100 with the filter film 130 is increased, which not only covers a predetermined color gamut, but also improves the color gamut of the light-emitting device 100 without the filter film 130. As shown in fig. 5, the color coordinate point of the green light can be changed from point a to point B by disposing the filter film 130, that is, the color coordinate of the green light is changed, and the light emitting gamut of the light emitting member 100 is changed from the first color gamut 1 to the second color gamut 2, and the light emitting gamut (i.e., the second color gamut 2) of the light emitting member 100 can cover the predetermined color gamut 3. Among them, the predetermined color gamut 3 may be an sRGB color gamut, an Adobe RGB color gamut, a DCI-P3 color gamut, an NTSC color gamut, or the like.
Alternatively, as shown in fig. 6, the light intensity of the green light can be increased by increasing the light emitting area of the green light emitting sub-pixel 122, so as to compensate the light intensity loss of the green light caused by the filter film 130, and thus the green light, the red light, and the blue light irradiated by the filter film 130 can reach a white balance under a certain condition. The light emitting area of the green light emitting sub-pixel 122 is larger than that of the red light emitting sub-pixel 121, and the light emitting area of the green light emitting sub-pixel 122 is larger than that of the blue light emitting sub-pixel 123.
Alternatively, the light intensity of the green light can be increased by increasing the light intensity of the green light-emitting sub-pixel 122, so as to compensate the light intensity loss of the green light caused by the filter film 130. As shown in fig. 7, the light emitting intensity of the green light emitting sub-pixel 122 can be increased by increasing the current driving the green light emitting sub-pixel 122. That is, the current driving the green light-emitting sub-pixel 122 to emit light is n times of the preset current of the green light-emitting sub-pixel 122, where n is equal to the ratio of the green light intensity required for achieving white balance to the light intensity of the light emitted by the green light-emitting sub-pixel 122111 after passing through the filter film 130.
Alternatively, the light intensity loss of the green light caused by the filter film 130 can be compensated by increasing the light emitting intensity and the light emitting area of the green light emitting sub-pixel 122. Referring to fig. 7, when the current for driving the green light-emitting sub-pixel 122 to emit light exceeds the set current threshold, the display area of the green light-emitting sub-pixel 122 may be increased, and then the driving current of the green light-emitting sub-pixel 122 is adjusted according to the ratio of the green light intensity required for achieving white balance to the light intensity of the light emitted by the green light-emitting sub-pixel 122 after passing through the filter film 130 until the driving current is less than or equal to the set current threshold. That is to say, the light emitting areas of the red light emitting sub-pixel 121 and the blue light emitting sub-pixel 123 may be smaller than the light emitting area of the green light emitting sub-pixel 122, and the current for driving the green light emitting sub-pixel 122 to emit light is n times of the preset current of the green light emitting sub-pixel 122, where n is equal to the ratio of the green light intensity required for achieving white balance to the light intensity of the light emitted by the green light emitting sub-pixel 122 after passing through the filter film 130. Therefore, the light emitting area and the driving current of the green light emitting sub-pixel 122 can be flexibly regulated, the driving current is not more than the set current threshold, and the stability of the light emitting element 100 is ensured.
Referring to fig. 8, fig. 8 is a schematic structural diagram of a light emitting element 200 according to an embodiment of the present application.
A light emitting device 200 includes a substrate 210, a group of light emitting pixels 220, a filling layer 240, and absorbing colored particles 2301 disposed in the filling layer. The plurality of light-emitting sub-pixel points 220 are disposed on the substrate 210. The filling layer 240 is formed on the substrate 210 and covers the light-emitting sub-pixel 220, so that the light-emitting element 200 is planarized. The absorption type colored particles are used for selectively absorbing the light emitted by the light emitting sub-pixel points 220, so that the wavelength range of the emitted light is narrowed, and the color coordinate adjustment of the emitted light is realized.
Specifically, the absorption type colored particles of the present embodiment are colored glass frit, and include a metal compound (generally, metal oxide) that can selectively absorb light incident on the colored glass frit 2301, and the type of the metal compound can be selected according to a wavelength band that needs to be filtered out in actual circumstances. Taking the present case as an example, when the color coordinate of the emitted green light needs to be adjusted, the colored glass powder that absorbs the wavelengths of 490nm to 505nm can be selected, and the dominant wavelength of the green light is adjusted to be 544nm by selective absorption of the wavelength range, so as to cover a larger color gamut range.
Referring to fig. 9, fig. 9 is a schematic structural diagram of a display panel 300 according to an embodiment of the present application. As shown in fig. 9, the display panel 300 includes a light emitting panel 310. The light emitting panel 310 includes one or more light emitting members 311. The light emitting element 311 may be the light emitting element provided in any of the above embodiments, and has corresponding technical features and technical effects, which are not described herein again.
In the present embodiment, as shown in fig. 9, the display panel 300 further includes a light blocking frame 320 and a diffusion film 330. The light shielding frame 320 may be disposed on the light emitting surface of the light emitting panel 310. As shown in fig. 10, the light shielding frame 320 may include a plurality of light guiding frames 321. Each light guiding frame 321 corresponds to a light emitting element 311. The light guide frame 321 forms a light path space 322. The light emitted from the light emitting members 311 is emitted through the light path space 322, so that the light crosstalk between different light emitting members 311 can be prevented.
In addition, the angle range of the light emitted from the light shielding frame 320 can be estimated by the height of the inner wall of the light path space 322, the position of the light emitting element 311, and the size of the light emitting surface of the light path space 322. For example, as shown in fig. 11, the inner wall of the light path space 322 may be perpendicular to the diffuser 330, and when viewed in a clockwise direction, the light emitted from the light shielding frame 320 may have an angle range
Where d is the size of the light emitting member 311 (e.g., when the light emitting member 311 is rectangular, one of the diagonal line, length, and width of the light emitting member 311; when the light emitting member 311 is circular, the diameter of the light emitting member 311, etc.), p is the size of the top surface of the light path space 322 (when the top surface of the light path space 322 is circular, the size of the top surface of the light path space 322 is circular, and when the top surface of the light path space 322 is rectangular, the size of the top surface of the light path space 322 is rectangular)Length/width/diagonal length), l is the closest distance of the light emitting member 311 to the inner wall of the light path space 322, and h is the vertical distance of the top of the light emitting member 311 to the top surface of the light path space 322. For another example, as shown in fig. 12, when the light emitting element 311 is located at the center of the surface of the light path space 322 opposite to the diffusion layer 330, the angle range of the light incident on the diffusion layer 330 may be
The angle range of the light incident on the diffusion layer 330 at this time may also be
Where d is the size of the light emitting element 311, h is the vertical distance from the light emitting element 311 to the top surface of the light path space 322 (the connecting surface of the light guiding frame 321 and the diffusion layer 330), p is the size of the top surface of the light path space 322 (when the top surface of the light path space 322 is circular, the size of the top surface of the light path space 322 is the diameter of the circle; when the top surface of the light path space 322 is rectangular, the size of the top surface of the light path space 322 is the length/width/diagonal length of the rectangle), and e is the wall thickness of the top end of the light guiding frame 321 (the connecting end of the light guiding frame 321 and the.
In this embodiment, the light guiding frame 321 may be formed such that the inner wall of the light path space 322 has a light absorbing surface. The light emitting member 311 may be located at a center of a side of the light path space 322 facing away from the diffusion layer 330.
In other embodiments, as shown in fig. 13, the light guide frame 321 may be formed such that the inner wall of the light path space 322 has a light reflecting surface. By reflecting the light emitted from the light emitting member 311 on the light reflecting surface a plurality of times, the color and intensity of the light emitted from the light blocking frame 320 are more uniform, and color differences at different viewing angles can be eliminated. The light blocking frame 320 having the light reflecting surface reflects only light and does not absorb light, and thus, the light intensity loss of the light emitted from the light emitting member 311 can be reduced. The light emitting element 311 may be located at a central position or a peripheral position of a surface of the light path space 322 facing away from the diffusion layer 330.
As shown in fig. 14, by disposing the diffusion film 330 on the light shielding frame 320, the light emitted from the light shielding frame 320 can be diffused and the light emitted from the display panel 300 can be more uniform. By providing the diffusion layer 330, light incident on the diffusion layer 330 is sufficiently diffused, so that the intensity and color of light output by the display panel 300 can be more uniform at different viewing angles, and color differences at different viewing angles can be eliminated.
The diffusion film 330 can be adhered to the light shielding frame 320 by an adhesive 340. A gap is formed between the light shielding frame 320 and the diffusion film 330, and light can be emitted from the adhesive 340 after being refracted, which is beneficial to improving the pixel filling rate of the display panel 300.
Alternatively, the diffuser film 330 may alternatively be a surface microstructured diffuser film. The light shielding frame 320 can be attached to the base surface of the diffusion film 330, so that the attaching effect is good, and the microstructure of the diffusion film 330 is not influenced.
Further, the surface microstructure diffuser film may employ a 80 ° gaussian scattering diffuser film 330. As shown in fig. 15, fig. 15 is a schematic diagram of the diffusion result of light incident on the surface microstructure diffusion film from different surfaces, and it can be seen that light can only obtain a 50% diffusion angle of 80 degrees from the microstructure surface, and can only obtain a 50% diffusion angle of 38 degrees from the base surface, so that the light shielding frame 320 is connected to the microstructure surface of the diffusion film 330 scattering at 80 ° of gaussian, and can obtain a 50% diffusion angle with a larger angle, which is more beneficial to the diffusion of light incident on the diffusion film 330, so that the light emitted by the diffusion film 330 is more uniform.
However, it is considered that the adhesion of the light shielding frame 320 to the microstructure surface affects the microstructure of the surface of the diffusion film 330. For this reason, the diffusion film 330 may be attached to the light shielding frame 320 in a non-full-surface attachment manner. For example, as shown in fig. 16, the adhesive 340 may be coated on the light shielding frame 320 or the diffusion film 330 by dispensing, so as to attach the light shielding frame 320 and the diffusion film 330. And the speed and the flow rate of dispensing can be adjusted in the dispensing process. For another example, as shown in fig. 17, the adhesive 340 may be continuously coated on the light shielding frame 320 or the diffusion film 330, or the coating of the adhesive 340 may be realized by a stamp transfer or an exposure development, so as to realize the attachment of the light shielding frame 320 and the diffusion film 330.
In other embodiments, the diffusion membrane 330 may also be a particle diffusion membrane.
Referring to fig. 18, fig. 18 is a schematic structural diagram of a display device 400 according to an embodiment of the present application. The display device 400 includes a display panel 410. The display panel 410 is the display panel 300 provided in any of the above embodiments, and has corresponding technical features and technical effects, which are not described herein again. The display device 400 shown in fig. 18 is only a schematic illustration, and the display device 400 may be any electronic device having a display function and including a display panel 410, such as a monitor, a mobile phone, a tablet computer, a notebook computer, an electronic book, or a television.
The above embodiments are merely examples, and not intended to limit the scope of the present application, and all modifications, equivalents, and flow charts using the contents of the specification and drawings of the present application, or those directly or indirectly applied to other related arts, are included in the scope of the present application.
