The invention provides a quantum dot substrate, a liquid crystal display panel and a double-sided liquid crystal display panel, wherein the quantum dot substrate comprises a substrate, a quantum dot layer and a frame glue, wherein the quantum dot layer is formed on the substrate, and the frame glue is coated on the quantum dot layer and the periphery of the quantum dot layer and used for supporting a film layer to form an air layer.

Description
Technical Field
The invention relates to the technical field of display, in particular to a quantum dot substrate, a liquid crystal display panel and a double-sided liquid crystal display panel, wherein the quantum dot substrate is used for improving the visual angle and the brightness of the liquid crystal display panel and improving the brightness uniformity.
Background
Since the viewing angle of the lcd tv is only about 60 ° to 80 ° in mass production, the consumer's demand for large viewing angle is not satisfied. Therefore, the manufacturers have found that if the quantum dot layer is directly attached to the side of the Polarizer (POL), the viewing angle can be effectively increased to 140 ° or more, but this also results in more loss of optical brightness. In addition, if the quantum dot layer is directly attached to the Light Guide Plate (LGP), the Light incident into the Light Guide Plate cannot be uniformly diffused due to the small difference in refractive index between the quantum dot layer and the Light Guide Plate, resulting in a problem of concentrated Light emission inside the Light Guide Plate. No matter the quantum dot layer is attached to the polarizer or the light guide plate, the quantum dot layer is prevented from directly contacting the polarizer or the light guide plate, and the ideal light effect can be achieved.
In order to solve the problem of optical brightness loss caused by direct attachment of the quantum dot layer to the polarizer, the national republic of China grant No. CN109581572A discloses a display panel in which a low refractive index layer is disposed between the quantum dot layer and the polarizer, thereby improving the color gamut and the overall light transmittance of the display panel.
However, the above-mentioned techniques require the preparation of an additional film layer (low refractive index layer) which causes a burden on the cost, and the low refractive index layer still causes a loss of optical brightness. Therefore, in order to improve the brightness of the display panel and improve the brightness uniformity, it is necessary to provide a quantum dot substrate to solve the problems in the prior art.

The following description of the various embodiments refers to the accompanying drawings, which illustrate embodiments of the invention and which are set forth in part in the description. Directional phrases used in connection with the present invention, such as "upper" or "lower", etc., refer only to the orientation of the appended drawings. Accordingly, the directional terms used are used for explanation and understanding of the present invention, and are not used for limiting the present invention.
Referring to fig. 1, fig. 1 is a schematic view of a quantum dot substrate 10 according to a first embodiment of the invention. The first embodiment of the present invention provides a quantum dot substrate 10, which includes a substrate 12, and a quantum dot layer 14 and a sealant 16 are sequentially formed on the substrate 12, wherein the substrate 12 may be a glass substrate or a flexible substrate.
In the present embodiment, the material of the quantum dot layer 14 includes a polymer transparent resin (not shown, as described below) and quantum dots (not shown, as described below) dispersed in the polymer transparent resin, wherein the polymer transparent resin can be used as a carrier of the quantum dots, so that the quantum dots are dispersed and fixed to form the quantum dot layer 14. Furthermore, the high molecular transparent resin can shield external oxygen and moisture, so that the quantum dots are encapsulated and protected, and the service life of the quantum dots is prolonged.
In the present embodiment, the quantum dot layer 14 may include a composite quantum dot layer structure having high stability, such as loading with hydrogel or CdSe — SiO2The quantum dot layer 14. It can be seen that the present invention is applicable to a variety of quantum dot layers 14.
In the present embodiment, the quantum dots have a particle diameter of 20 nanometers (nm) to 1 micrometer (μm), and are formed of II-VIA、III-VA、II-VAThe nano-particles composed of the material can even be perovskite quantum dots with high stability. It can be seen that the present invention is applicable to a variety of quantum dots. Specifically, the quantum dots comprise red light quantum dots and green light quantum dots, wherein each quantum dot comprises a luminescent core and an inorganic material wrapped outside the luminescent coreAnd protecting the shell layer. The red light material of the luminescent core comprises CdSe and Cd2SeTe and InAs, etc., the green material of the luminescent core comprises ZnCdSe2InP and Cd2Sse, etc., the inorganic protective shell layer comprises CdS, ZnSe and ZnCdS2One or more of ZnS and ZnO.
Further, referring to fig. 2, fig. 2 is a schematic diagram of a quantum dot substrate 20 including a red quantum dot layer 242 and a green quantum dot layer 246 according to a second embodiment of the present invention. The red and green quantum dots may be mixed in a polymer transparent resin to form the quantum dot layer 14 shown in fig. 1. The red light quantum dots and the green light quantum dots can also be mixed in the polymer transparent resin respectively to form a red light quantum dot layer 242 and a green light quantum dot layer 244 which are sequentially disposed above the substrate 22. In another embodiment, the order of the red quantum dot layer 242 and the green quantum dot layer 244 can be reversed to form the green quantum dot layer 244 and the red quantum dot layer 242 sequentially disposed over the substrate 22. For convenience of explanation, the quantum dot layer 24 is the case including the red quantum dot layer 242 and the green quantum dot layer 244 unless explicitly stated otherwise below.
In conjunction with the above description and fig. 3, fig. 3 is a top view of a quantum dot substrate 30 according to a first embodiment of the present invention. In order to solve the problem of optical brightness loss and brightness non-uniformity caused by the quantum dot layer 34 directly attached to a Polarizer (POL) or a Light Guide Plate (LGP) in the prior art, the invention coats the sealant 36 on and around the quantum dot layer 34, so that the sealant 36 can support the film layer (including the Polarizer or the Light guide plate) thereon and form an air layer therebetween, instead of the low refractive index layer in the prior art. Furthermore, the sealant 36 not only prevents the quantum dot layer 34 from directly contacting the polarizer or the light guide plate, but also does not cause the light efficiency of the display region to be reduced because the sealant 36 is formed in the non-display region. In another embodiment, the sealant 36 may also span the non-display region and the display region.
In conjunction with the above description and fig. 4 to 6, fig. 4 is a schematic view of a quantum dot substrate 40 having a light diffusion particle layer 48 according to a third embodiment of the present invention, fig. 5 is a schematic view of a quantum dot substrate 50 having a light diffusion particle layer 58 according to a fourth embodiment of the present invention, and fig. 6 is a schematic view of a quantum dot substrate 60 having a light diffusion particle layer 68 according to a fifth embodiment of the present invention. The quantum dot substrate of the present invention may further include light diffusion particles (not shown), which are inorganic nanoparticles having a refractive index of 2 or more and a particle diameter of 20nm to 1 μm, such as titanium dioxide, zirconium dioxide, and the like. The light diffusing particles are intended to spread incident light in all directions, thereby increasing the contact of light with quantum dots or helping to improve viewing angle. The light diffusion particles may be mixed with quantum dots in the polymer transparent resin and formed on a substrate to form a quantum dot layer 14 as shown in fig. 1. In another embodiment, the light diffusing particles may form the film layer alone. Specifically, the light diffusion particle layer 48 may be disposed and attached to a side of the substrate 42 away from the quantum dot layer 44 (as shown in fig. 4), the light diffusion particle layer 58 may be disposed between the substrate 52 and the quantum dot layer 54 (as shown in fig. 5), and the light diffusion particle layer 68 may also be disposed between the quantum dot layer 64 and the sealant 66 (as shown in fig. 6).
Further, if the quantum dot layer is divided into a red quantum dot layer and a green quantum dot layer, the light diffusion particles can be mixed in the red quantum dot layer and the green quantum dot layer, respectively. The light diffusing particle layer may also be formed between the red quantum dot layer and the green quantum dot layer.
In summary, if the quantum dot layer is on the uppermost layer, a water-oxygen barrier layer can be evaporated or attached on the quantum dot layer, so as to prevent oxygen and moisture from entering and prolong the service life of the quantum dot.
Referring to fig. 7, fig. 7 is a schematic diagram of a liquid crystal display panel 702 with a quantum dot substrate 70 according to a sixth embodiment of the invention. The lcd panel 702 includes a quantum dot substrate 70, a first polarizer 7022, and a lcd region 7024 and a second polarizer 7026 sequentially formed on the first polarizer 7022, wherein the quantum dot substrate 70 is disposed below the first polarizer 7022 and includes a substrate 72, a quantum dot layer 74, and a sealant 76 according to the first to fifth embodiments of the present invention. In this optical system, the quantum dot layer 74, if directly bonded to the first polarizer 7022, results in about a 75% loss in overall brightness, including a 50% polarization loss and 25% other losses. By arranging the sealant 76 between the quantum dot layer 74 and the first polarizer 7022 and forming an air layer therebetween, the present invention can avoid optical loss other than polarization loss, reduce brightness loss to 50%, and improve light efficiency.
Referring to fig. 8, fig. 8 is a schematic view illustrating a quantum dot substrate 80 attached to a light guide 8022 according to a seventh embodiment of the present invention. The quantum dot substrate 80 includes a substrate 82, a quantum dot layer 84, and a sealant 86 according to the first to fifth embodiments of the present invention. In this optical system, since the light guide plate 8022 is disposed at the lowermost portion of the liquid crystal display panel, the quantum dot layer 84 is formed below the substrate 82, and the sealant 86 is formed below the quantum dot layer 84. It should be understood that this is by way of directional terms used to illustrate the present embodiments and should not be used to limit the present invention. Since the quantum dot layer 84 has a small difference in refractive index between the quantum dot layer 84 and the light guide plate 8022 if the quantum dot layer 84 is directly attached to the light guide plate 8022, when incident light (not shown) enters the light guide plate, the light cannot be diffused to the entire light guide plate and is scattered. According to the invention, the sealant 86 is arranged between the quantum dot layer 84 and the light guide plate 8022, and an air layer (with a refractive index of 1) is formed between the quantum dot layer 84 and the light guide plate 8022, so that the difference of the refractive indexes of the quantum dot layer 84 and the light guide plate 8022 is increased, light can be totally reflected in the light guide plate, and incident light is diffused into the whole light guide plate, thereby improving the uniformity of the scattered brightness.
Referring to fig. 9, fig. 9 is a schematic view of a double-sided liquid crystal display panel (Dual Cell) with a quantum dot substrate 90 according to an eighth embodiment of the invention. The double-sided liquid crystal display panel includes a first polarizer 9021, and a first liquid crystal display region 9022, a second polarizer 9023, a quantum dot substrate 90, a third polarizer 9024, a second liquid crystal display region 9025, and a fourth polarizer 9026 sequentially formed on the first polarizer 9021, wherein the quantum dot substrate 90 includes a substrate 92, a quantum dot layer 94, and a sealant 96 according to the first to fifth embodiments of the present invention. In the optical system, if the quantum dot layer 94 is directly attached to the third polarizer 9024, optical loss similar to that described in the sixth embodiment of the present invention may be caused, and thus, is not described herein again. According to the invention, the frame glue 96 is arranged between the quantum dot layer 94 and the third polarizer 9024, and an air layer is formed between the frame glue 96 and the quantum dot layer, so that optical loss except polarization loss is avoided, and the light efficiency is improved. In addition, the second polarizer 9026 is directly attached to the side of the substrate 92 away from the quantum dot layer 94. In another embodiment, the quantum dot substrate 90 may also be located below the first polarizer 9021, such that a sealant 96 is disposed between the quantum dot layer 94 and the first polarizer 9021, and an air layer is formed therebetween, such that the quantum dot substrate 90 is closer to the backlight (not shown).
Although the present invention has been described with reference to the preferred embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, and that various changes and modifications may be effected therein by one skilled in the art without departing from the scope of the invention as defined by the appended claims.
