EMBODIMENTS OF THE INVENTION

Detailed Description of the Preferred Embodiments

The technical solutions in some embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in some embodiments of the present application. It should be understood, the described embodiments are only some of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of this application.

Referring to FIG. 1, FIG. 1 is a schematic structural diagram of a display panel according to some embodiments of the present application. Some embodiments of the present application provide a display panel 100, which includes a display substrate 10 and a color filter substrate 20 disposed oppositely.

The display substrate 10 includes a TFT substrate 11, a plurality of light-emitting devices 13 and a light-absorbing layer 14, wherein the plurality of light-emitting devices 13 and the light-absorbing layer 14 provided on a side of the TFT substrate 11. The light-absorbing layer 14 is provided in the spacing area in each of the plurality of light-emitting devices 13 and around each of the plurality of light-emitting devices 13 (That is, the light-absorbing layer 14 is provided between two adjacent light-emitting devices 13, and the light-absorbing layer 14 is also provided at the edge position outside the light-emitting device 13).

The color filter substrate 20 includes a first substrate 21, a plurality of color filters 22 and a black matrix 23, wherein the plurality of color filters 22 and the black matrix 23 provided on a side of the first substrate 21. The black matrix 23 is provided with a plurality of hollow areas, each of the plurality of color filters 22 is disposed in a corresponding one of the plurality of hollow areas, and the color filter 22 is disposed relative with a corresponding one of the plurality of light-emitting devices 13; the color filter substrate 20 also includes a plurality of color conversion layers 24 and a plurality of reflective blocking walls 25, the color conversion layers 24 are provided on a side of the color filter 22 away from the first substrate 21, and the reflective blocking wall 25 is provided on a side of the black matrix 23 away from the first substrate 21.

The side of the display substrate 10 provided which the plurality of light-emitting devices 13 and the light-absorbing layer 14 faces the side of the color filter substrate 20 on which the plurality of color conversion layers 24 and the reflective blocking wall 25 are located.

In some embodiments, the side of the display substrate 10 on which the plurality of light-emitting devices 13 and the light-absorbing layer 14 are disposed is connected with the side of the color filter substrate 20 provided with the plurality of color conversion layers 24 and the reflective blocking wall 25 through an adhesive layer 30.

It should be understood that in the display panel 100 provided by the embodiment of the present application, it can be defined that in the vertical direction, one light-emitting device 13, one color conversion layer 24, and one color filter 22 correspond to each other to form one pixel. When the display panel 100 displays a picture and requires the light-emitting device 13 in a certain pixel to emit light, the reflective effect on the surface of the spacing area in light-emitting device 13 on the display substrate 10 may lead the light reflected from the spacing area to pass through the adhesive layer 30 and enter the color conversion layer 24 and color filter 22 of adjacent pixels to cause interference to adjacent pixels. Especially, the crosstalk of reflected light may accidently light up the adjacent pixels which are not need to be lit, resulting in poor display. This application provides a light-absorbing layer 14 on the surface of the spacing area in the light-emitting device 13 on the display substrate 10, which can effectively solve the problem of light crosstalk caused by reflection and improve the display effect of the display panel 100.

In the display panel 100 provided by the embodiment of the present application, a light-absorbing layer 14 is provided in the display substrate 10, a plurality of light-emitting devices 13 is corresponding disposed in a plurality of hollow areas on the light-absorbing layer 14, and the color filter 22 and the color conversion layer 24 in the color filter substrate 20 are disposed correspondingly with the light-emitting devices 13. The light-absorbing layer 14 can be used to absorb the light emitted to the spacing area in the light-emitting device 13 on the display substrate 10 to avoid interference caused by reflecting light emitted by light-emitting devices 13 through the surface of the spacing area onto the color conversion layer 24 and the color filter 22 of the adjacent pixels. Thus, the problem of poor display performance caused by light crosstalk between adjacent pixels is avoided, and the display effect of the display panel 100 is improved.

Referring to FIG. 1. The TFT substrate 11 includes a stacked second substrate 111 and a TFT device layer 112, wherein the plurality of light-emitting devices 13 and the light-absorbing layer 14 are provided on a side of the TFT device layer 112 away from the second substrate 111, and the plurality of light-emitting devices 13 are electrically connected to the TFT device layer 112.

In some embodiments, a material of the light absorbing layer 14 is black metal oxide. In some embodiments, the black metal oxide is molybdenum oxide.

Referring to FIG. 2, FIG. 2 is a schematic structural diagram of the light-absorbing layer according to some embodiments of the present application. In some embodiments, the light-absorbing layer 14 includes a first metal layer 141, a light-transmitting medium layer 143, and a second metal layer 142 stacked in sequence. The first metal layer 141 is disposed adjacent to the TFT substrate 11. The first metal layer 141 includes one or more of copper (Cu), silver (Ag) and aluminum (AL); the second metal layer 142 includes one or more of molybdenum (Mo) and titanium (Ti); and the light-transmitting medium layer 143 includes one or more of metal oxide, silicon oxide (SiOx), and silicon nitride (SiNx).

It should be noted that by arranging the light-absorbing layer 14 into a structure in which the first metal layer 141, the light-transmitting medium layer 143 and the second metal layer 142 are stacked in sequence; the first metal layer 141, the light-transmitting medium layer 143 and the second metal layer 142 can form a resonant cavity. Since the material of the second metal layer 142 (molybdenum, titanium) has better light absorption properties, part of the light entering the second metal layer 142 is absorbed, and the other part of the light passes through the second metal layer 142 and enters the resonant cavity. After entering the resonant cavity, the light can be reflected back and forth between the second metal layer 142 and the first metal layer 141, but can no longer be emitted from the second metal layer 142, thereby achieving the light absorption effect. In addition, compared with the solution in which all materials of the light-absorbing layer 14 are made of molybdenum and/or titanium, this stacked structure costs relatively lower on material.

In other embodiments, the material of the light absorbing layer 14 includes organic black materials. In some embodiments, the organic black material is a mixture of organic resin material and black pigment.

It should be understood that the function of the reflective blocking wall 25 is to separate adjacent pixels and prevent the emitted light of the light-emitting device 13 and the emitted light of the color conversion layer 24 in one pixel from entering the color conversion layer 24 and color filter 22 in the adjacent pixel, thereby preventing interference to adjacent pixels. In some embodiments, the reflectivity of the reflective blocking wall 25 is above 85%, such as 85%, 90%, 95%, 100%, etc.

In some embodiments, a material of the reflective blocking wall 25 includes an organic material and an inorganic material, wherein the organic material includes one or more of BT resin, silica gel, methyl methacrylate (MMA), and polyimide (PI). The BT (Bismaleimide triazine) resin is prepared by using bismaleimide (BMI) and triazine as the main resin components, and adding epoxy resin, polyphenylene ether resin (PPE) or allyl compounds as modified components, to form a thermosetting resin. The inorganic material includes one or more of titanium dioxide (TiO2) and tantalum pentoxide (Ta2O5).

In some embodiments, the color of the reflective blocking wall 25 is white.

In some embodiments, the height of the reflective blocking wall 25 is greater than the height of the color conversion layer 24, so that the emitted light of the color conversion layer 24 in adjacent pixels can be prevented from interfering with each other.

In some embodiments, the height difference between the reflective blocking wall 25 and the color conversion layer 24 is between 1/10 and ½ of the height of the light emitting device 13 (for example, 1/10, 1/9, ⅛, 1/7, ⅙, ⅕, ¼, ⅓, ½, etc.).

In some embodiments, the height of the reflective blocking wall 25 is 20 μm or more (for example, 20 μm, 23 μm, 25 μm, 28 μm, 30 μm, etc.).

In some embodiments, the material of the reflective blocking wall 25 is a hydrophilic material, and the material of the color conversion layer 24 is a hydrophobic material. In this case, the polarities of the materials of the reflective blocking wall 25 and the material of the color conversion layer 24 are mutually exclusive. Therefore, the reflective blocking wall 25 can be manufactured by spraying. When the polarities of the materials are mutually exclusive, the material of the reflective blocking wall 25 cannot be adsorbed on the color conversion layer 24 thereby avoiding a pollution. In addition, in some embodiments of the present application, due to the low cost of the spraying process, the manufacturing cost of the reflective blocking wall 25 is low.

Specifically, the material of the color conversion layer 24 includes one or more of quantum dot materials, phosphor materials, and phosphorescent photoluminescent materials. In some embodiments, the quantum dot material includes one or more of CdS/CdSe, InP, and perovskite quantum dots, and wherein the phosphor material includes one or more of YAG phosphor, silicate phosphor, and nitride phosphor. The phosphorescent photoluminescence materials include KSF.

In some embodiments, the color conversion layer 24 may convert the light emitted by the light-emitting device 13 into light with a wavelength ranging from 500 nm to 660 nm.

In some embodiments, the light converted by the color conversion layer 24 can be a combination of green light (G) and red light (R), yellow light (Y); a combination of yellow light (Y) and red light (R); and a combination of green light (G) and orange light (O), etc.

In some embodiments, the plurality of light-emitting devices 13 can all be blue light-emitting devices, and the light converted by the color conversion layer 24 can be a combination of green light and red light. In this case, the color conversion layer 24 generates green excitation light and red excitation light under the excitation of blue light emitted by the light-emitting device 13, wherein the green excitation light, red excitation light and remaining unexcited blue light are mixed to form white light.

In some embodiments, the light-emitting device 13 is an LED chip. It should be understood that compared with the technical solutions of transferring red light Micro LED chips, green light Micro LED chips, and blue light Micro LED chips together, the plurality of light-emitting devices 13 are all blue-light light-emitting devices of the present application, and only a single-color chip (here is the blue Micro LED chip) needs to be transferred, which can increase the transfer efficiency of the LED chip by 3 times and reduce the transfer cost. In addition, because the cost of the blue Micro LED chip is cheaper than the red Micro LED chip and the green Micro LED chip, so the cost of LED chips can be further reduced.

In some embodiments, the pixel structure of the display panel 100 is RGBW, RGB, RGBC, RGBY, RGBC, RGBYC, RGBYM, RGBCM, RGBYC, WYCM and other pixel structure designs; where R is red, G is green, and B is blue, W is white, M is magenta (including B and R colors), Y is yellow (including G and R colors), and C is cyan (including B and G colors).
