[0032] The present invention provides a display panel.

[0033] In the embodiments of the present invention, as Figure 1 shown, the display panel includes an array substrate 100, a counter substrate 200, and liquid crystal 400. The array substrate 100 and the counter substrate 200 are disposed opposite to each other. The liquid crystal 400 is disposed between the array substrate 100 and the counter substrate 200. The counter substrate 200 includes a plurality of color filter units 210. Each color filter unit 210 includes at least two color filter blocks. The display panel further includes a reflective filter 220 and a semi-reflective semi-transmissive lens group 300. The reflective filter 220 is disposed on the side of the color filter block facing the array substrate 100 and is used to filter at least one color of light and can reflect at least one other color of light; the color of at least one kind of light filtered by the reflective filter 220 is the same as the color of the light transmitted through the opposite color filter block; the semi-reflective semi-transmissive lens group 300 is used to transmit the light from the array substrate 100 to the counter substrate 200 direction and is used to reflect the light reflected by the reflective filter 220; the semi-reflective semi-transmissive lens group 300 is disposed on the array substrate 100; or, the semi-reflective semi-transmissive lens group 300 is disposed on the counter substrate 200 and on the side of the reflective filter 220 facing the array substrate 100.

[0034] The opposing substrate 200 includes a plurality of color-resist units 210, and each color-resist unit 210 includes at least two color-resist blocks. In one example, each color-resist unit 210 includes at least two of a red color-resist block 211, a blue color-resist block 213, and a green color-resist block 212; in another example, each color-resist unit 210 may further include color-resist blocks of other colors, such as yellow, white, etc. When light passes through the red color-resist block 211, red light is emitted; when light passes through the blue color-resist block 213, blue light is emitted; when light passes through the green color-resist block 212, green light is emitted. In the technical solution of the present invention, by providing a reflection filter 220 on the side of the color-resist block facing the array substrate 100, the reflection filter 220 can filter at least one color of light and can also reflect at least one other color of light, and at least one color of the light filtered by the reflection filter 220 is the same as the color of the light filtered by the opposing color-resist block. Thus, it can be ensured that when light passes through the color-resist block, at least the corresponding color of light can be emitted, and at least one other color of light is reflected and directed towards other color-resist blocks for secondary penetration, thereby improving the display brightness of the display panel. For example, the reflection filter 220 provided below the red color-resist block 211 can only allow red light to pass through and can reflect other colors of light other than red light (such as blue light and green light). Similarly, the reflection filter 220 provided below the blue color-resist block 213 can only allow blue light to pass through and can reflect other colors of light other than blue light (such as red light and green light). The reflection filter 220 provided below the green color-resist block 212 can only allow green light to pass through and can reflect other colors of light other than green light (such as blue light and red light). Or, the reflection filter 220 provided below the red color-resist block 211 can allow red light to pass through, can also allow one of blue light and green light to pass through, and can reflect the other one of blue light and green light. Similarly, the reflection filter 220 provided below the blue color-resist block 213 can allow blue light to pass through, can also allow one of red light and green light to pass through, and can reflect the other one of red light and green light. The reflection filter 220 provided below the green color-resist block 212 can only allow green light to pass through, can also allow one of blue light and red light to pass through, and can reflect the other one of blue light and red light.

[0035] The display panel in the technical solution of the present invention further includes a semi-reflective semi-transmissive lens group 300. The semi-reflective semi-transmissive lens group 300 transmits the light in the direction from the array substrate 100 to the counter substrate 200, so as to ensure that normal light can pass through the color resistance blocks and avoid the semi-reflective semi-transmissive lens group 300 from blocking the incident light. In addition, the semi-reflective semi-transmissive lens group 300 can also reflect the light reflected by the reflection filter 220, so that the light not filtered by the reflection filter 220 is reflected again by the semi-reflective semi-transmissive lens group 300 and then directed to adjacent or similar color resistance blocks of other colors. Furthermore, the reflected light can have the same color as the color resistance blocks of other colors it is directed to, so as to pass through the adjacent or similar color resistance blocks of other colors, thereby improving the light utilization rate and achieving the display effect of a high-brightness picture without increasing power consumption. For example, one of the reflection filters 220 can filter red light and reflect blue light and green light. Then the reflected blue light and green light are directed to the semi-reflective semi-transmissive lens group 300, and the semi-reflective semi-transmissive lens group 300 further reflects the blue light and green light again, thereby changing the propagation direction of the light, so that the blue light reflected again by the semi-reflective semi-transmissive lens group 300 can be directed to adjacent or similar blue color resistance blocks 213, and the green light reflected again by the semi-reflective semi-transmissive lens group 300 can be directed to adjacent or similar green color resistance blocks 212, thus improving the light utilization rate and increasing the display brightness of the display panel. Similarly, another reflection filter 220 can filter blue light and reflect red light and green light. Then the reflected red light and green light are directed to the semi-reflective semi-transmissive lens group 300, and the semi-reflective semi-transmissive lens group 300 further reflects the red light and green light again, thereby changing the propagation direction of the light, so that the red light reflected again by the semi-reflective semi-transmissive lens group 300 can be directed to adjacent or similar red color resistance blocks 211, and the green light reflected again by the semi-reflective semi-transmissive lens group 300 can be directed to adjacent or similar green color resistance blocks 212, thus improving the light utilization rate and increasing the display brightness of the display panel. Similarly, another reflection filter 220 can filter green light and reflect red light and blue light. Then the reflected red light and blue light are directed to the semi-reflective semi-transmissive lens group 300, and the semi-reflective semi-transmissive lens group 300 further reflects the red light and blue light again, thereby changing the propagation direction of the light, so that the red light reflected again by the semi-reflective semi-transmissive lens group 300 can be directed to adjacent or similar red color resistance blocks 211, and the blue light reflected again by the semi-reflective semi-transmissive lens group 300 can be directed to adjacent or similar blue color resistance blocks 213, thus improving the light utilization rate and increasing the display brightness of the display panel.

[0036] Specifically, the semi-reflective and semi-transmissive lens group 300 can be disposed on the array substrate 100, that is, the semi-reflective and semi-transmissive lens group 300 belongs to a part of the array substrate 100; or the semi-reflective and semi-transmissive lens group 300 is disposed on the counter substrate 200 and on the side of the reflective filter 220 facing the array substrate 100. In both cases, the light emitted from the array substrate 100 towards the counter substrate 200 can pass through the semi-reflective and semi-transmissive lens group 300, and the light reflected by the reflective filter 220 can be reflected by the semi-reflective and semi-transmissive lens group 300, thereby improving the light utilization rate.

[0037] In the technical solution of the present invention, a reflective filter 220 is disposed on the side of the color resist block facing the array substrate 100. The reflective filter 220 can filter at least one color of light, and at least one color of the light is the same as the color of the light filtered by the color resist block corresponding to the reflective filter 220, and can reflect at least one other color of light. Thus, the light emitted from the array substrate 100 towards the counter substrate 200 can ensure that the light of the color corresponding to the color resist block is filtered, and can reflect at least one of the other colors of light for reuse of the reflected light. In addition, by disposing the semi-reflective and semi-transmissive lens group 300 on the side of the array substrate 100 or the counter substrate 200 where the reflective filter 220 faces the array substrate 100, the semi-reflective and semi-transmissive lens group 300 can transmit the light emitted from the array substrate 100 towards the counter substrate 200, and can reflect the light reflected by the reflective filter 220. Thus, the light reflected by the reflective filter 220 can be secondarily reflected and emitted towards adjacent or similar color resist blocks, so as to improve the light utilization rate through the adjacent or similar color resist blocks, and increase the display brightness of the display panel without increasing power consumption.

[0038] In one embodiment, as Figure 1 shown, each color resist unit 210 includes at least three color resist blocks, where the three color resist blocks are a red color resist block 211, a green color resist block 212, and a blue color resist block 213 respectively; the reflective filter 220 includes a first reflective filter 221, a second reflective filter 222, and a third reflective filter 223. The first reflective filter 221 is disposed on the side of the red color resist block 211 facing the array substrate 100 to filter red light and reflect light of other colors; the second reflective filter 222 is disposed on the side of the green color resist block 212 facing the array substrate 100 to filter green light and reflect light of other colors; the third reflective filter 223 is disposed on the side of the blue color resist block 213 facing the array substrate 100 to filter blue light and reflect light of other colors.

[0039] By setting at least three color filter blocks, where the three color filter blocks are a red color filter block 211, a blue color filter block 213, and a green color filter block 212 respectively, the light passing through these three color filter blocks can be mixed to produce a variety of colors, and these three color filter blocks can be used as a color filter unit 210. The reflective filter 220 includes a first reflective filter 221, a second reflective filter 222, and a third reflective filter 223. The first reflective filter 221 is disposed on the side of the red color filter block 211 facing the array substrate 100, and is used to filter red light and reflect light of other colors, so as to ensure that red light can pass through the reflective filter 220 and the red color filter, ensure that red light is emitted from the position corresponding to the red color filter, and also ensure that light of other colors (such as green light and blue light) can be reflected by the first reflective filter 221 to the semi-reflective semi-transmissive lens group 300, and then reflected to the adjacent color filter block through the secondary reflection of the semi-reflective semi-transmissive lens group 300, so that the adjacent blue color filter block 213 can absorb the blue light that has undergone the secondary reflection of the semi-reflective semi-transmissive lens group 300 again, or so that the adjacent green color filter block 212 can absorb the green light that has undergone the secondary reflection of the semi-reflective semi-transmissive lens group 300 again, thereby improving the utilization rate of each color of light. Similarly, the second reflective filter 222 is disposed on the side of the green color filter block 212 facing the array substrate 100, and is used to filter green light and reflect light of other colors, so as to ensure that green light can pass through the reflective filter 220 and the green color filter, ensure that green light is emitted from the position corresponding to the green color filter, and also ensure that light of other colors (such as red light and blue light) can be reflected by the second reflective filter 222 to the semi-reflective semi-transmissive lens group 300, and then reflected to the adjacent color filter block through the secondary reflection of the semi-reflective semi-transmissive lens group 300, so that the adjacent blue color filter block 213 can absorb the blue light that has undergone the secondary reflection of the semi-reflective semi-transmissive lens group 300 again, or so that the adjacent red color filter block 211 can absorb the red light that has undergone the secondary reflection of the semi-reflective semi-transmissive lens group 300 again, thereby improving the utilization rate of each color of light. Similarly, the third reflective filter 223 is disposed on the side of the blue color filter block 213 facing the array substrate 100, and is used to filter blue light and reflect light of other colors, so as to ensure that blue light can pass through the reflective filter 220 and the blue color filter, ensure that blue light is emitted from the position corresponding to the blue color filter, and also ensure that light of other colors (such as red light and green light) can be reflected by the third reflective filter 223 to the semi-reflective semi-transmissive lens group 300, and then reflected to the adjacent color filter block through the secondary reflection of the semi-reflective semi-transmissive lens group 300, so that the adjacent green color filter block 212 can absorb the green light that has undergone the secondary reflection of the semi-reflective semi-transmissive lens group 300 again, or so that the adjacent red color filter block 211 can absorb the red light that has undergone the secondary reflection of the semi-reflective semi-transmissive lens group 300 again, thereby improving the utilization rate of each color of light.

[0040] In one embodiment, please refer to Figure 1 and Figure 2 , the semi-reflective and semi-transmissive lens group 300 includes a convex lens 310 and a semi-reflective and semi-transmissive film 320. The convex lens 310 has at least a convex surface protruding in a direction away from the reflective filter 220; the semi-reflective and semi-transmissive film 320 is disposed on a side of the convex surface away from the reflective filter 220.

[0041] By providing the convex lens 310, and the convex lens 310 has at least a convex surface protruding in a direction away from the reflective filter 220, and the semi-reflective and semi-transmissive film 320 is disposed on a side of the convex surface away from the reflective filter 220, the light reflected by the reflective filter 220 can pass through the convex lens 310 and irradiate onto the semi-reflective and semi-transmissive film 320, and the light passing through the convex lens 310 has a converging effect, avoiding the risk that part of the light is directed to other areas outside the opening area due to excessive divergence of the light.

[0042] Furthermore, as Figure 2 shown, the surface of the convex lens 310 facing the reflective filter 220 is a plane.

[0043] By setting the surface of the convex lens 310 facing the reflective filter 220 as a plane, at least one side of the semi-reflective and semi-transmissive lens group 300 is a plane, which facilitates the setting of other film layers on the semi-reflective and semi-transmissive lens group 300 and ensures good flatness of the whole. In addition, it can ensure that the light emitted from the array substrate 100 to the counter substrate 200 has a collimation effect and ensure a good display effect.

[0044] Furthermore, as Figure 2 shown, the semi-reflective and semi-transmissive lens group 300 further includes a concave lens 330. The concave lens 330 is disposed on a side of the semi-reflective and semi-transmissive film 320 away from the reflective filter 220, and the concave lens 330 has a concave surface facing the convex lens 310.

[0045] The semi-reflective and semi-transmissive lens group 300 further includes a concave lens 330, and the concave lens 330 is disposed on a side of the semi-reflective and semi-transmissive film 320 away from the reflective filter 220, so that the concave lens 330 is disposed on a side close to the convex surface of the convex lens 310. And because the concave lens 330 has a concave surface facing the convex lens 310, the concave lens 330 and the convex lens 310 can be fitted together, that is, the convex surface of the convex lens 310 can be matched with the concave surface of the concave lens 330. Thus, when the two are provided together, the risk that the convex lens 310 is unstable due to its convex surface can be avoided. At this time, the semi-reflective and semi-transmissive film 320 is disposed between the convex surface of the convex lens 310 and the concave surface of the concave lens 330. Specifically, the semi-reflective and semi-transmissive film 320 can be attached or plated on the convex surface of the convex lens 310, or can be attached or plated on the concave surface of the concave lens 330, or there can be a gap between the semi-reflective and semi-transmissive film 320 and both the convex surface of the convex lens 310 and the concave surface of the concave lens 330.

[0046] Further, as Figure 2 shown, the semi-transmissive and semi-reflective film 320 is attached to the concave surface of the concave lens 330 facing the convex lens 310, and the curved radian of the semi-transmissive and semi-reflective film 320 is adapted to the concave radian of the concave lens 330.

[0047] With such a setting, on the one hand, it can ensure that the light reflected by the reflection filter 220 can be converged by the convex lens 310 and then reflected by the semi-transmissive and semi-reflective film 320. On the other hand, it can make the combination process of the components in the semi-transmissive and semi-reflective lens group 300 simpler and the assembled structure more compact, and the stability of the semi-transmissive and semi-reflective film 320 can be ensured during the installation process.

[0048] Further, as Figure 2 shown, the surface of the concave lens 330 away from the convex lens 310 is a plane.

[0049] By setting the surface of the concave lens 330 away from the convex lens 310 as a plane, the side of the semi-transmissive and semi-reflective lens group 300 facing away from the reflection filter 220 is a plane, so that it is convenient to set the whole semi-transmissive and semi-reflective lens group 300 on the array substrate 100 and ensure the stability of the installation of the semi-transmissive and semi-reflective lens group 300.

[0050] Further, as Figure 1 shown, the convex lens 310 and the concave lens 330 are attached to each other.

[0051] By attaching the convex lens 310 and the concave lens 330 to each other, on the one hand, it can ensure the stability of the installation of the convex lens 310 and the concave lens 330, ensure the firmness of the whole semi-transmissive and semi-reflective lens group 300, make the concave lens 330 and the convex lens 310 support each other, and reduce the setting of other support components. On the other hand, it can make the whole thickness of the semi-transmissive and semi-reflective lens group 300 smaller, and further make the thickness of the whole display panel smaller.

[0052] In an example, as Figure 1 shown, the semi-transmissive and semi-reflective lens group 300 is arranged on the array substrate 100.

[0053] By arranging the semi-transmissive and semi-reflective lens group 300 on the array substrate 100, it can ensure that there is enough distance between the semi-transmissive and semi-reflective lens group 300 and the reflection filter 220, so as to ensure that the light reflected by the reflection filter 220 can effectively pass through the secondary reflection of the semi-transmissive and semi-reflective lens group 300 and enter the adjacent or similar color resistance blocks, thereby improving the utilization rate of light.

[0054] In one example, the light reflected by the first reflection filter 221 can be scattered to the green color filter block 212 and the blue color filter block 213 which are adjacent to the red color filter block 211 after being reflected again by the semi-reflective semi-transmissive lens group 300; the light reflected by the second reflection filter 222 can be scattered to the blue color filter block 213 and the red color filter block 211 which are adjacent to the green color filter block 212 after being reflected again by the semi-reflective semi-transmissive lens group 300; the light reflected by the third reflection filter 223 can be scattered to the green color filter block 212 and the red color filter block 211 which are adjacent to the blue color filter block 213 after being reflected again by the semi-reflective semi-transmissive lens group 300.

[0055] With such a setting, it can ensure that the light is fully utilized, improve the display brightness of the display panel, and reduce power consumption. In addition, with such a setting, it can also ensure that most of the light reflected by the semi-reflective semi-transmissive lens group 300 is located in the opening area, reducing the risk that the light enters the non-opening area and affects its utilization rate. Specifically, in order to ensure that the reflected light can enter the adjacent color filter blocks, it can be achieved by adjusting the curvature radius of the semi-reflective semi-transmissive lens group 300. In addition, it can also change the refractive index by changing the material of the semi-reflective semi-transmissive lens group 300, thereby changing the reflection direction of the light so that the reflected light is directed into the adjacent color filter blocks; or, it can also ensure that the reflected light can be directed to the adjacent color filter blocks for further utilization by changing the width size and spacing of each color filter block.

[0056] The present invention also provides a display device, as Figure 3 shown. The display device includes a backlight module 500 and a display panel. The specific structure of the display panel refers to the above embodiments. Since the present display device adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.
