[0022] Please refer to Figures 1 to 3 , Figure 1 is a schematic diagram of a first embodiment of a projection device 100 of the present invention, Figure 2 is a partial schematic diagram of the first metal layer in the projection device 100 of the present invention, Figure 3 The projection device 100 of the present invention comprises a light source 10 , a liquid crystal panel 20 and a lens 30 . The light emitted by the light source 10 passes through the liquid crystal panel 20 and then is transmitted to the lens 30 .

[0023] Combination Figure 2 and Figure 3As shown, the liquid crystal panel 20 includes an array substrate 210, a color filter substrate 220 and a liquid crystal molecule layer 230. The array substrate 210 and the color filter substrate 220 are arranged opposite to each other. The liquid crystal molecule layer 230 is sandwiched between the array substrate 210 and the color filter substrate 220. The color filter substrate 220 is located between the array substrate 210 and the light source 10, so that the light emitted by the light source 10 first passes through the color filter substrate 220 and then enters the array substrate 210. The base material 201 of the color filter substrate 220 has a first surface s1 and a second surface s2 opposite to each other. The first surface s1 faces the light source 10 (i.e., away from the array substrate 210), and the second surface s2 faces the array substrate 210. The first surface s1 is provided with an APCF (Advanced polarization conversion film) layer 221 and a first polarizing layer 222. The APCF layer 221 is located between the light source 10 and the first polarizing layer 222, and the transmission axes of the APCF layer 221 and the first polarizing layer 222 are consistent. The second surface s2 is provided with a first metal layer M1 and a plurality of color resist blocks 223 . The first metal layer M1 has a plurality of hollow regions h arranged in an array. The plurality of color resist blocks 223 are correspondingly located in the plurality of hollow regions h.

[0024] In one embodiment, an example is given in which the first polarizing layer 222 allows P polarized light to pass through but prevents S polarized light from passing through. The light source 10 emits natural light containing P polarized light and S polarized light. If the APCF layer 221 is not provided, after the light emitted from the light source 10 passes through the first polarizing layer 222, only the P polarized light therein can reach the substrate 201 of the color filter substrate 200. However, in the present invention, in which the APCF layer 221 and the first polarizing layer 222 are provided and the transmission axis of the APCF layer 221 is consistent with the transmission axis of the first polarizing layer 222, after the natural light reaches the APCF layer 221, only the P polarized light can pass through the APCF layer 221. Since the transmission axis of the first polarizing layer 222 is consistent with the transmission axis of the APCF layer 221, the P polarized light passing through the APCF layer 221 continues to pass through the first polarizing layer 222 and reaches the substrate 201 of the color filter substrate 220. The S polarized light cannot pass through the APCF layer 221 and is reflected back. The reflected light returns to the area where the light source 10 is located, and is reflected by the light source 10 and emitted again in the form of natural light. In the natural light emitted again, the P polarized light can pass through the APCF layer 221 and the first polarizing layer 222 and reach the base material 201 of the color film substrate 220, while the S polarized light is still reflected back by the APCF layer 221, and is reflected by the light source 10 again and emitted again in the form of natural light. This cycle repeats itself, and each time the S polarized light is reflected back by the APCF layer 221, it will turn back into natural light and be emitted to the APCF layer 221 again, so that part of the P polarized light is emitted, so that the light reaching the base material 201 of the color film substrate 220 can theoretically be close to the amount of light emitted by the light source 10, thereby improving the transmittance of the light emitted by the light source 10 reaching the base material 201 of the color film substrate 220 after passing through the first polarizing layer 222.

[0025] The substrate 201 of the color filter substrate 220 is a light-transmitting substrate. The light reaching the substrate 201 of the color filter substrate 220 can pass through the substrate 201 of the color filter substrate 220. If the first metal layer M1 is not provided but the black matrix layer of the prior art is used, only part of the light reaching the substrate 201 of the color filter substrate 220 can pass through the area where the multiple color blocks 223 are located, and the light irradiated to the black matrix layer will be absorbed by the black matrix layer. In the case where the first metal layer M1 is provided in the present invention, the light incident to the multiple hollow areas h of the first metal layer M1 can directly pass through the multiple hollow areas h and be incident to the multiple color blocks 223, and continue to be transmitted toward the array substrate 210 after passing through the multiple color blocks 223. The light incident on the first metal layer M1 is blocked by the first metal layer M1 and reflected back. The reflected light passes through the first polarizing layer 222 and the APCF layer 221 in sequence and returns to the area where the light source 10 is located. After being reflected by the light source 10, it is emitted again in the form of natural light. In the re-emitted natural light, the P polarized light can pass through the APCF layer 221 and the first polarizing layer 222 to reach the base material 201 of the color film substrate 220. The light incident on the multiple hollow areas h can directly pass through the multiple hollow areas h and be incident on the multiple color blocking blocks 223. The light from the first metal layer M1 is blocked by the first metal layer M1 and reflected back, and this cycle repeats. Each time the light reflected back by the first metal layer M1 will turn into natural light again and then be emitted to the APCF layer 221, the first polarizing layer 222, the base material 201 of the color film substrate 220 and the first metal M1. Part of the light can be emitted from the multiple hollow areas h of the first metal layer M1, thereby increasing the amount of light emitted by the light source 10 that enters the color resist layer CF after reaching the base material 201 of the color film substrate 220, thereby increasing the transmittance of the light.

[0026] In the present embodiment, an APCF polarizing functional layer (i.e., a combination of an APCF layer 221 and a first polarizing layer 222) is arranged on the surface of the color film substrate 220 facing the light source 10, and a first metal layer M1 is arranged on the surface of the color film substrate 220 facing the array substrate 210. The APCF polarizing functional layer is used to increase the transmittance of the light emitted by the light source 10 reaching the base material 201 of the color film substrate 220, and the first metal layer M1 is used to increase the transmittance of the light after reaching the base material 201 of the color film substrate 220 and entering the color resist layer CF, thereby increasing the overall transmittance of the liquid crystal panel 10 in the projection device 100 and improving the user experience.

[0027] In the above embodiment, the APCF layer 221 and the first polarizing layer 222 are used as an example to illustrate that the P polarized light can pass through and the S polarized light cannot pass through, but the present invention is not limited thereto. In another embodiment, the first polarizing layer 222 is used to allow the S polarized light to pass through and the P polarized light cannot pass through.

[0028] like Figure 2As shown, the first metal layer M1 includes a plurality of first metal strips l1 extending along a first direction F1 and a plurality of second metal strips l2 extending along a second direction F2, the first direction F1 intersects with the second direction F2, each first metal strip l1 has a first width w1, each second metal strip l2 has a second width w2, and the first width w1 is smaller than the second width w2. In this embodiment, the first direction F2 is perpendicular to the second direction F2, but the invention is not limited thereto. In one embodiment, a plurality of data lines may be arranged on the array substrate 210 corresponding to the plurality of first metal strips l1, and a plurality of gate lines may be arranged corresponding to the plurality of second metal strips l2, but the invention is not limited thereto.

[0029] like Figure 1 and Figure 3 As shown, the substrate of the array substrate 210 has a third surface s3 , which faces away from the color filter substrate 220 . A second polarizer 211 is disposed on the third surface s3 , and a transmission axis of the second polarizer 211 is perpendicular to a transmission axis of the first polarizing layer 222 .

[0030] In one embodiment, the light source 10 is a white light LED or a combination of red, green and blue light LEDs to provide the aforementioned natural light. Figure 1 As shown, the projection device 100 further includes a first Fresnel lens 40 and a second Fresnel lens 50. The first Fresnel lens 40 is located between the light source 10 and the APCF layer 221, and the second Fresnel lens 50 is located between the array substrate 210 and the lens 30. The light source 10 can be arranged at the focus of the first Fresnel lens 40, and the lens 30 can be arranged at the focus of the second Fresnel lens 50. The light emitted by the light source 10 is collimated by the first Fresnel lens 40 and then incident on the APCF layer 221, the first polarizing layer 222, the substrate of the color filter substrate 220, the color resist layer CF, the liquid crystal molecule layer 230, the substrate of the array substrate 210, and the second polarizing layer 211. The light emitted from the liquid crystal panel 20 can be a light beam carrying image information, and then is focused by the second Fresnel lens 40 onto the lens 30, amplified, and projected onto the target projection surface for imaging.

[0031] like Figure 1 As shown, the projection device 100 may further include a through-hole reflector cup 60 to further improve the utilization rate of light. The reflector cup 60 is in a truncated cone shape, and the inner surface of the reflector cup 60 may have a high reflectivity, for example, coated with an aluminum film layer. The reflector cup 60 has a first bottom 61 and a second bottom 62 opposite to each other, and the cross-sectional area of ​​the first bottom 61 is smaller than the cross-sectional area of ​​the second bottom 62. The first bottom 61 is sleeved on the light source 10, and the second bottom 62 is sleeved on the first Fresnel lens 40.

[0032] In one embodiment, the first metal layer M1 is a molybdenum layer, but is not limited thereto. Figure 3As shown, the first metal layer M1 has a first thickness, and the plurality of color blocks 223 have a second thickness. The first thickness is not greater than the second thickness, for example, the first thickness is less than one-half, one-third, or even one-fifth of the second thickness. The first metal layer M1 is mainly used to reflect the light directed toward it back to the light source 10. By setting the thickness of the first metal layer M1 to be less than (or even much less than) the thickness of the plurality of color blocks 223, the manufacturing cost of the liquid crystal panel 20 can be effectively controlled. Please refer to Figure 4 , Figure 4 FIG. 2 is a partial schematic diagram of another embodiment of a liquid crystal panel in a projection device of the present invention. Figure 4 As shown, in this embodiment, a black matrix layer BM is further provided on the color filter substrate 220, and the black matrix layer BM covers the first metal layer M1. The black matrix layer BM overlaps with the projection of the first metal layer M1 on the color filter substrate 220, so that the black matrix layer BM and the first metal layer M1 can have the same hollow area h. By providing the black matrix layer BM, the overall thickness of the composite structure composed of the first metal layer M1 and the black matrix layer BM can be ensured when the first metal layer M1 is relatively thin, so as to ensure that the hollow area h plays an effective guiding / blocking function in the process of forming the color resist layer CF.

[0033] Further, such as Figure 4 As shown, in this embodiment, in addition to the first metal layer M1 and the black matrix layer BM, a second metal layer M2 may be further provided on the color film substrate 220, and the second metal layer M2 covers the black matrix layer BM. The second metal layer M2 overlaps with the projection of the black matrix layer BM on the color film substrate 220, so that the first metal layer M1, the black matrix layer BM and the second metal layer M2 may have the same hollow area h.

[0034] A driving circuit is usually provided on the surface of the array substrate 210 facing the color filter substrate 220, and the driving circuit includes an opaque metal layer. After passing through the color resist layer CF, the light is incident on the array substrate 210, and a part of the light passes through the area where the opaque metal layer is not provided and then is emitted to the lens 30, and another part of the light is incident on the area where the opaque metal layer is provided and then is blocked by the opaque metal layer and is reflected back. In the prior art, only a black matrix layer is provided on the color filter substrate 220, and if the light reflected back by the opaque metal layer reaches the black matrix layer, it is absorbed by the black matrix layer. In this embodiment, by providing the second metal layer M2, if the light reflected back by the opaque metal layer reaches the second metal layer M2, it can be reflected by the second metal layer M2, change direction and then be re-emitted to the array substrate 220. In this way, the amount of light passing through the array substrate 210 can be increased, and the transmittance of the light can be increased. In addition, by means of the sandwich stacking structure of the first metal layer M1 , the black matrix layer BM and the second metal layer M3 , the first metal layer M1 and the second metal layer M2 are controlled to have a thinner thickness, thereby controlling the production cost while improving the light transmittance.

[0035] Figure 1 In the projection device 100 shown, the surface of the color filter substrate 220 facing the light source 10 is provided with an APCF layer 221 and a first polarizing layer 222 as an APCF polarizing functional layer. In actual operation, the APCF polarizing functional layer can also be a single component, that is, the APCF layer and the polarizing layer can be integrated into an APCF polarizing plate. Figure 5 , Figure 5 FIG. 2 is a schematic diagram of a second embodiment of the projection device of the present utility model. Figure 5 As shown, the projection device 100' comprises a light source 10, a liquid crystal panel 20' and a lens 30. The light emitted by the light source 10 passes through the liquid crystal panel 20 and is transmitted to the lens 30. The liquid crystal panel 20' comprises an array substrate 210, a color filter substrate 220' and a liquid crystal molecule layer 230. The array substrate 210 and the color filter substrate 220' are arranged opposite to each other. The liquid crystal molecule layer 230 is sandwiched between the color filter substrate 220' and the array substrate 210. The color filter substrate 220' is located between the array substrate 210 and the light source 10. The base material 201 of the color film substrate 220' has a first surface and a second surface relative to each other, the first surface faces the light source 10, and the second surface faces the array substrate 210. The first surface is provided with an APCF polarizing plate 221', and the second surface s2 is provided with a first metal layer M1 and a color resist layer (not shown). The color resist layer includes a plurality of color resist blocks. The first metal layer M1 has a plurality of hollow areas (not shown) arranged in an array, and the plurality of color resist blocks are correspondingly located in the plurality of hollow areas.

[0036] The APCF polarizing plate 221' allows P polarized light to pass through but prevents S polarized light from passing through. Similar to the principle of the first embodiment, the light source 10 emits natural light, and after the natural light reaches the APCF polarizing plate 221', only the P polarized light can pass through the APCF polarizing plate 221' and reach the base material 201 of the color filter substrate 220. The S polarized light cannot pass through the APCF polarizing plate 221' and is reflected back. The reflected light returns to the area where the light source 10 is located, and is reflected by the light source 10 and emitted again in the form of natural light. In the re-emitted natural light, the P polarized light can pass through the APCF polarizing plate 221' and reach the base material 201 of the color film substrate 220, while the S polarized light is still reflected back by the APCF polarizing plate 221' and is emitted again in the form of natural light after being reflected by the light source 10. This goes on and on. Each time the S polarized light reflected back by the APCF polarizing plate 221' is converted back into natural light and emitted to the APCF polarizing plate 221' again, a portion of the P polarized light is emitted, thereby increasing the transmittance of the light emitted by the light source 10 to the base material 201 of the color film substrate 220. It should be noted that the other component arrangements of the projection device 100' are similar to those of the projection device 100 in the first embodiment and are not described in detail.

[0037] In the utility model, an APCF polarizing functional layer is arranged on the surface of the color film substrate facing the light source, and a metal layer is arranged on the surface of the color film substrate facing the array substrate. The APCF polarizing functional layer is used to improve the transmittance of the light emitted by the light source reaching the base material of the color film substrate, and the metal layer is used to improve the transmittance of the light after reaching the base material of the color film substrate and entering the color resistance layer. Therefore, the transmittance of the liquid crystal panel in the projection device is improved, and the user experience is improved.

[0038] The above detailed description of the preferred embodiments is intended to more clearly describe the features and spirit of the present invention, rather than to limit the scope of protection of the present invention by the preferred embodiments disclosed above. On the contrary, the purpose is to include various changes and arrangements with equivalents within the scope of protection of the claims to be applied for the present invention. Therefore, the scope of protection of the claims of the present invention should be interpreted in the broadest sense based on the above description, so as to include all possible changes and arrangements with equivalents.
