[0056] Please refer to Figure 5 , Figure 5 For Figure 4A cross-sectional view of the display panel along the IV-IV direction is shown. In the embodiment, the display panel 30 includes an array substrate 31, a liquid crystal layer 32, and a color film substrate 33, the array substrate 31 and the color film substrate 33 are oppositely and spacedly arranged, and the liquid crystal layer 32 is arranged between the array substrate 31 and the color film substrate 33, i.e., the color film substrate 33 is arranged on the side of the liquid crystal layer 32 away from the array substrate 31. Part of the array substrate 31 is located in the display area 30a, and part of the array substrate 31 is located in the non-display area 30b. The liquid crystal layer 32 is located in the display area 30a, part of the color film substrate 33 is located in the display area 30a, and part of the color film substrate 33 is located in the non-display area 30b.

[0057] In the embodiment, the display panel 30 further includes a first liquid crystal polarizing component 34 and a second liquid crystal polarizing component 35, the first liquid crystal polarizing component 34 is arranged on the side of the array substrate 31 away from the liquid crystal layer 32, and the second liquid crystal polarizing component 35 is arranged on the side of the color film substrate 33 away from the liquid crystal layer 32. Part of the first liquid crystal polarizing component 34 can be located in the display area 30a, and part of the first liquid crystal polarizing component 34 can be located in the non-display area 30b. Part of the second liquid crystal polarizing component 35 can be located in the display area 30a, and part of the second liquid crystal polarizing component 35 can be located in the non-display area 30b. The first liquid crystal polarizing component 34 and the second liquid crystal polarizing component 35 are used to control the polarization direction of the backlight light, and convert the backlight light provided by the backlight module 10 into polarized light backlight to realize image display.
[0058] In an embodiment of the present application, the first liquid crystal polarizing component 34 and the second liquid crystal polarizing component 35 can be a coated liquid crystal polarizing plate, which mainly consists of liquid crystal molecules and dichroic dye, and the liquid crystal material and the dye are combined by coating process to form a thin film with polarization function, allowing polarized light in a specific direction to pass through, thereby forming linearly polarized light required for liquid crystal display, and controlling the transmission direction of light to achieve image display. In the prior art, due to the low transmittance of the polarizing plate and the reflection of light on the surface of the polarizing plate, the light loss is large and the light brightness is insufficient, which is difficult to meet the effect and demand of transparent display. Therefore, the first liquid crystal polarizing component 34 and the second liquid crystal polarizing component 35 can accurately control the transmission direction of light, balance the degree of polarization and transmittance, improve the brightness and contrast of the display panel 30, and enhance the light and dark contrast of the screen.

The dye liquid crystal layer can be formed of dichroic dye liquid crystal, which realizes color display through dichroism. The alignment layer can be made of polyimide (PI), which can control the arrangement direction of liquid crystal molecules. Therefore, by making the dye liquid crystal layer on the alignment layer, the liquid crystal molecules are arranged in a specific direction under the action of the alignment layer, and the dye molecules are distributed in a specific direction with the liquid crystal molecules, which not only realizes the polarization function, but also improves the transmittance of light, thereby improving the brightness and contrast of the display panel 30 and enhancing the light and dark contrast of the screen. Moreover, the first liquid crystal polarizing component 34 and the second liquid crystal polarizing component 35 do not need the stretching process of the traditional polarizing plate, but can form a polarization structure through coating and orientation treatment, solving the problems of insufficient brightness of the transmitted light and poor contrast caused by the low transmittance and large light loss of the traditional polarizing plate.

The display panel 30 further includes a color resistance layer 36, which is arranged between the liquid crystal layer 32 and the color film substrate 33, i.e. the color resistance layer 36 is arranged on the side of the color film substrate 33 away from the second liquid crystal polarizing component 35. As shown in Figure 6As shown, the color resist layer 36 includes a plurality of color resist units arranged in an array, that is, the plurality of color resist units 361 are arranged in a multi-row, multi-column array, and the plurality of color resist units 361 are arranged along a first direction (e.g., Figure 6 The multiple color resist units 361 are arranged adjacent to each other along the second direction (e.g., the X direction). Figure 6 The Y-direction of the first direction is arranged adjacent to each other, wherein the first direction is perpendicular to the second direction.
[0061] In this embodiment, each color resist unit 361 includes a transparent region T and a color resist region P. The transparent region T surrounds the periphery of the color resist region P, and the area of the transparent region T is 1 to 3 times the area of the color resist region P, for example, 1, 1.2, 1.5, 2, 2.2, 2.5, 2.8, 3, or other values. This application does not impose specific limitations on this. That is, the ratio of the area of the transparent region T to the area of the color resist region P is any value from 1 to 3, for example, 1, 1.2, 1.5, 2, 2.2, 2.5, 2.8, 3, or other values. This application does not impose specific limitations on this. The transparent regions T of adjacent color resist units 361 are adjacent to each other.
[0062] In this embodiment, the color resist region P is provided with k color resist elements P1, P2, ..., Pk that display different colors. Here, k, referring to the number of color resist elements included in one color resist unit 361, can be three or four, and this application does not specifically limit this. Within one color resist unit 361, the color resist elements P1, P2, ..., Pk can be arranged adjacent to each other along the first direction. Therefore, each of the plurality of color resist units 361 includes a transparent region T, and thus, each color resist unit 361 can include a transparent display structure. Due to such a transparent display structure, the transparent display panel and transparent display device of this application are realized.
[0063] like Figure 6As shown, in the embodiment of the present application, three color resist elements showing different colors are arranged in each color resist region P, i.e., a first color resist element P1, a second color resist element P2 and a third color resist element P3 are arranged in each color resist region P, and the first color resist element P1, the second color resist element P2 and the third color resist element P3 in one color resist unit 361 are arranged adjacent to each other along the first direction and show different colors. That is, in one color resist unit 361, the transparent region T is arranged around the first color resist element P1, the second color resist element P2 and the third color resist element P3, and the area of the transparent region T is greater than or equal to the sum of the areas of the first color resist element P1, the second color resist element P2 and the third color resist element P3.
[0064] In the embodiment of the present application, the first color resist element P1 is used to convert part of the backlight into first color light, the second color resist element P2 is used to convert part of the backlight into second color light, and the third color resist element P3 is used to convert part of the backlight into third color light. Wherein, the first color resist element P1 can be a red color resist, the second color resist element P2 can be a green color resist, the third color resist element P3 can be a blue color resist, the backlight can be white light, the first color light can be red light, the second color light can be green light, and the third color light can be blue light, i.e., the first color can be red, the second color can be green, and the third color can be blue.
[0065] It can be understood that the transparent region T of each color resist unit 361 of the display panel 30 is arranged around the color resist region P, and the area of the transparent region T is greater than or equal to the area of the color resist region P. That is, in one color resist unit 361, the transparent region T is arranged around the first color resist element P1, the second color resist element P2 and the third color resist element P3, and the area of the transparent region T is greater than or equal to the sum of the areas of the first color resist element P1, the second color resist element P2 and the third color resist element P3. Therefore, the transparency of the color resist unit 361 can be increased (e.g., the transparency can be greater than 50%), and based on such a transparent display structure, not only the transparent display function of the display panel 30 is realized, but also the aperture ratio of the transparent display panel can be further increased.
[0066] Please refer to Figure 5 , Figure 7 and Figure 8 , Figure 7 for Figure 5 the second arrangement diagram of the color resist unit in the color resist layer, Figure 8 Figure 7 The diagram shows the structure of the color resist unit. Figure 7 The second arrangement of the color resist units shown is similar to Figure 6 The difference in the first arrangement of the color resist units shown is that the color resist elements within the color resist unit 361 are arranged differently from those in the transparent region T. Specifically, the transparent region T includes multiple sub-transparent regions, and the color resist region P contains multiple color resist elements that display different colors. Within each color resist unit 361, the multiple sub-transparent regions and the multiple color resist elements are arranged alternately along the first direction. For a description of the similarities between the second and first arrangements of the color resist units 361, please refer to the above description of the first arrangement of the color resist units 361; it will not be repeated here.
[0067] In one embodiment of this application, as Figure 7 and Figure 8 As shown, the transparent area T includes a first sub-transparent area T1, a second sub-transparent area T2, and a third sub-transparent area T3. Each color resist area P is provided with a first color resist element P1, a second color resist element P2, and a third color resist element P3. Within a color resist unit 361, the first color resist element P1, the third color resist element P3, and the second color resist element P2 can be arranged to be spaced apart from each other along the first direction and display different colors. The first color resist element P1, the first sub-transparent region T1, the third color resist element P3, the second sub-transparent region T2, the second color resist element P2, and the third sub-transparent region T3 are arranged sequentially. That is, within one color resist unit 361, the first sub-transparent region T1 is located between the first color resist element P1 and the third color resist element P3, the second sub-transparent region T2 is located between the third color resist element P3 and the second color resist element P2, and the third sub-transparent region T3 is located on the side of the second color resist element P2 that is opposite to the second sub-transparent region T2. In other words, the third sub-transparent region T3 is located between the second color resist element P2 and the first color resist element P1 of another color resist unit 361 adjacent in the first direction.
[0068] In the embodiments of the present application, the sum of the areas of the first, second and third sub-transparent regions T1, T2 and T3 is 1 to 3 times, for example, 1 times, 1.2 times, 1.5 times, 2 times, 2.2 times, 2.5 times, 2.8 times, 3 times, or other values, the sum of the areas of the first, second and third color-resistance elements P1, P2 and P3, and the present application does not make a specific limitation on this. That is, the ratio of the sum of the areas of the first, second and third sub-transparent regions T1, T2 and T3 to the sum of the areas of the first, second and third color-resistance elements P1, P2 and P3 is any value in the range of 1 to 3, for example, 1, 1.2, 1.5, 2, 2.2, 2.5, 2.8, 3, or other values, and the present application does not make a specific limitation on this. It can also be described that the area of the transparent region T is 1 to 3 times the area of the color-resistance region P, or the ratio of the area of the transparent region T to the area of the color-resistance region P is any value in the range of 1 to 3.
[0069] In the embodiments of the present application, the sub-transparent regions and the color-resistance elements are all rectangular, that is, the first, second and third sub-transparent regions T1, T2 and T3 are all rectangular, and the first, second and third color-resistance elements P1, P2 and P3 are also all rectangular, but the present application does not make a specific limitation on this.
[0070] In a specific embodiment of the present application, the area of the first color-resistance element P1 is equal to the area of the first sub-transparent region T1, the area of the third color-resistance element P3 is equal to the area of the second sub-transparent region T2, and the area of the second color-resistance element P2 is equal to the area of the third sub-transparent region T3. That is, the sum of the areas of the first, second and third sub-transparent regions T1, T2 and T3 is equal to the sum of the areas of the first, second and third color-resistance elements P1, P2 and P3.
[0071] In the embodiments of the present application, the first color-resistance element P1 is used to convert part of the backlight into first color light, the second color-resistance element P2 is used to convert part of the backlight into second color light, and the third color-resistance element P3 is used to convert part of the backlight into third color light. Wherein, the first color-resistance element P1 can be a red color-resistance, the second color-resistance element P2 can be a green color-resistance, the third color-resistance element P3 can be a blue color-resistance, the backlight can be white light, the first color light can be red light, the second color light can be green light, and the third color light can be blue light, that is, the first color can be red, the second color can be green, and the third color can be blue.
[0072] It can be understood that the plurality of sub-transparent regions in each of the color resistance units 361 of the display panel 30 are arranged alternately with the plurality of color resistance elements, and the area of the transparent region T is greater than or equal to the area of the color resistance region P. That is, in one of the color resistance units 361, the first color resistance element P1, the first sub-transparent region T1, the third color resistance element P3, the second sub-transparent region T2, the second color resistance element P2, and the third sub-transparent region T3 are arranged in sequence, and the sum of the areas of the first sub-transparent region T1, the second sub-transparent region T2, and the third sub-transparent region T3 is greater than or equal to the sum of the areas of the first color resistance element P1, the second color resistance element P2, and the third color resistance element P3. Therefore, by uniformly spacing the color resistance elements and the transparent regions in the color resistance unit 361, not only can the image display effect of the display panel 30 be improved to be more uniform, but also the transparency of the color resistance unit 361 can be increased (for example, the transparency can be greater than 50%). Moreover, based on such a transparent display structure, not only is the transparent display function of the display panel 30 realized, but also the aperture ratio of the transparent display panel can be further increased.
[0073] It can be understood that in the embodiments of the present application, the transparent region T refers to a non-light-emitting area, and the film layer of the transparent region T has high light transmittance, for example, the transparent region T can be a transparent pixel region. The transparent display panel and the transparent display device composed of the transparent display panel of the present application are not limited to the above-mentioned embodiments. In addition, the number, arrangement manner, and shape of the transparent region T and the color resistance region P, and the sub-transparent region and the color resistance element in each color resistance unit in each embodiment or the variant embodiment of the present application are only examples for illustrating the spirit of the present application, and are not intended to limit the content of the present application.
