The present application is described in detail below with reference to the figures and alternative embodiments.

Fig. 1 is a schematic structural diagram of a liquid crystal display panel according to a first embodiment of the present application; as shown in fig. 1, as a first embodiment of the present application, a liquid crystal display panel 100 is disclosed, where the display panel includes an array substrate 110, a color filter substrate 120, and a liquid crystal layer 130 disposed between the array substrate 110 and the color filter substrate 120, and a polarizer 150 is disposed on a surface of the color filter substrate 120 away from the array substrate 110, and considering that a transmittance of blue light is lower than that of red light and green light, a box thickness of the region is increased after liquid crystal is collected, which leads to a lower transmittance of blue light, and in a light mixing stage, a ratio of red light to green light is larger, which leads to yellow light mixed out, thereby affecting a display effect, a filter film 140 prepared by using a yellow dye is disposed between the color filter substrate and the polarized light, and the filter film 140 absorbs red light and green light, and effectively weakens red light and green light, so as to achieve a normal effect of color and brightness display of the liquid crystal display panel 100.

The liquid crystal display panel further includes a shift structure 160, the filter 140 and the shift structure 160 are both disposed between the polarizer 150 and the color filter substrate 120, and the shift structure 160 is movably connected to the filter 140; the color filter substrate 120 includes a substrate 121, a color resist layer 122 formed on the substrate 121, and a color resist trace 123 formed on the substrate 121 and connected to the color resist layer 122, wherein the filter 140 is disposed corresponding to the color resist trace; the filter 140 is made of a yellow dye-doped transparent glass film layer, when the liquid crystal display panel 100 is placed horizontally to be erected, the shift structure 160 shifts the filter 140 according to a component force change of gravity borne by the filter 140 in a direction parallel to the shift structure 160, and when a resistance of the shift structure 160 to the filter 140 is equal to a component force of gravity borne by the filter 140 in a direction parallel to the shift structure 160, the filter 140 moves from a position corresponding to the color resist routing line 123 to a position corresponding to the color resist layer 122.

Generally, when the liquid crystal display panel 100 is laid flat, since the gravity generated by the filter 140 is balanced with the resistance between the filter 140 and the displacement structure 160, the filter 140 is partially located on the color-resistance trace 123 structure, and there is no filtering effect, which is a normal display status; in the process that the liquid crystal display panel 100 is gradually and vertically placed, as the inclination angle increases, after the component force of the gravity borne by the filter film 140 in the direction of the displacement structure overcomes the resistance of the air below, the filter film 140 gradually descends, when the component force of the gravity borne by the filter film 140 in the direction of the displacement structure is reduced to the corresponding position of the color resistance layer 122, the displacement structure 160 and the filter film 140 compress the air until the component force of the filter film 140 in the direction of the displacement structure 160 is balanced with the resistance of the air below, the filter film 140 keeps stable and does not move any more, and at the moment, the light passes through the color resistance layer 122 and reaches the filter film 140, the filter film 140 doped with the yellow dye can absorb the red light and the green light, has no blocking effect on the red light and the green light, thereby actually reducing the ratio of the red light and the green light in the light, reducing the transmittance of the red light and the green light, further enabling the ratio of the transmitted red light and green light to be close to the blue light, thereby solving the problem that the blue light is yellowish in color due to the reduced blue light due to the weak self-penetrating ability, and improving the display effect.

As a second embodiment of the present application, which is a further refinement of the first embodiment, referring to fig. 1 to 3, the liquid crystal display panel 100 includes a display area 200 and a non-display area 300, the non-display area 300 is disposed around the display area 200, the display area 200 includes a first area 210 and a second area 220, when the liquid crystal display panel 100 is vertically placed, the first area 210 is above, and the second area 220 is below; the filter 140 is disposed only in the second region 220, and a projection area of the filter 140 is smaller than or equal to a projection area of the color resist 122 in a direction in which the polarizer 150 faces the color resist 122.

After the liquid crystal is influenced by gravity, the second area 220 below the first area 210 is easy to collect the liquid crystal after falling, the box thickness of the collection position is increased after the liquid crystal after falling is collected, the color is yellow, the filter film 140 is mainly arranged in the second area 220 of the display area 200 and does not need to be arranged in the first area 210, the preparation material and the preparation time are reduced, the cost is further saved under the condition of solving the problem that the liquid crystal panel is yellow, and the yield is improved.

Furthermore, through the detection of the yellowing area, the yellowing area of the liquid crystal display panel is mainly concentrated at about 5cm of the lower end of the liquid crystal panel, and the yellowing problem in the range can be clearly seen by naked eyes, so that the watching experience of a user is greatly influenced, and the product sale is not facilitated; in other areas, yellowing is hard to be found by naked eyes and is also within an allowable range, for this, referring to fig. 4, a second area 220 in a display area 200 is further refined, wherein the second area 220 comprises a first sub-area 221 and a second sub-area 222, the first sub-area 221 is located between the first area 210 and the second sub-area 222, when a liquid crystal display panel is erected, the width d of the second sub-area 222 is 3-5cm along the gravity direction, and the width of the second sub-area 222 is the distance from the side of the second sub-area 222 far from the first sub-area 221 to the side of the second sub-area 222 close to the first sub-area 221; the filter 140 is only located in the first sub-region 221; precise improvement is made for severe areas of yellowing problems, avoiding waste of materials and reducing the time required for the preparation of relevant films and structures.

As shown in fig. 5, as a third embodiment of the present application, which is a further refinement of the second embodiment, the displacement structure 160 includes a rectangular frame 161 and a micro gas spring 162 disposed on the rectangular frame 161, the micro gas spring is movably connected to the rectangular frame, and two ends of the filter film 140 are respectively fixedly connected to the micro gas spring 162; when the liquid crystal display panel 100 is laid flat, the gas pressure inside the micro gas spring 162 is balanced, and the filter film 140 is partially positioned on the color-resistance routing structure, so that the filter effect is not generated, and the display state is normal; in the process that the liquid crystal display panel 100 is gradually vertically placed, as the inclination angle increases, after the component force of the gravity of the filter film 140 in the direction of the micro gas spring overcomes the resistance of the gas below the filter film 140, the filter film 140 gradually descends along the gravity direction, when the filter film 140 corresponds to the position of the color resistance layer, the compressed gas below the micro gas spring 162 is stable when being balanced with the resistance of the gas below the micro gas spring, and at the moment, the red light and the green light in the light passing through the color resistance layer are greatly absorbed by the filter film formed by preparing yellow dye, so that the proportion of the red light and the green light in the light is reduced, the transmittance of the red light and the green light is reduced, the proportion of the transmitted red light and the green light and the blue light is close, and the problem that the color of the lower end of the liquid crystal display panel is yellow is solved.

The rectangular frame 161 comprises a first frame 1611, a second frame 1612, a third frame 1613 and a fourth frame 1614 which are fixedly connected end to end in sequence, wherein the first frame 1611 and the third frame 1613 are equal in length, and the second frame 1612 and the fourth frame 1614 are equal in length; the same segment of the micro gas spring 162 is fixed on the second frame 1612 and the fourth frame 1614 respectively; in the direction in which the polarizer faces the color filter substrate, the thicknesses of the first frame 1611 and the third frame 1613 are equal, the thicknesses of the second frame 1612 and the fourth frame 1614 are equal, and the thickness of the first frame 1611 is greater than the thickness of the second frame 1612, so that a sufficient space is reserved for the up-and-down movement of the filter film 140.

The color filter substrate 120 includes an edge region 124 and a middle region 125, the edge region 124 is disposed around the middle region 125, the rectangular frame 161 is disposed corresponding to the edge region 124 of the color filter substrate 120, and in a direction along the polarizer toward the color filter substrate 120, the non-display region covers the edge region 124, and the edge region 124 covers the rectangular frame 161.

The edge region 124 covers the rectangular frame 161, so that the first region 210 is prevented from having no supporting structure, and the polarizer is prevented from inclining toward the first region 210 due to the existing gap, which is easy to cause fragments, and the rectangular frame 161 is arranged corresponding to the whole color film substrate 120, so that the stability between the polarizer and the color film substrate can be improved. Of course, the rectangular frame may also be disposed corresponding to the second region 220 or the first sub-region 221 in the second region 220, and in the first region 210 or the second sub-region 222, other transparent materials may be used to fill between the polarizer and the color filter substrate, so as to ensure uniformity of a film layer in the liquid crystal display panel.

As shown in fig. 6, as a fourth embodiment of the present application, which is a further refinement of the above-mentioned embodiments, the filter film includes a plurality of light filtering bars 141, and a ratio of the yellow dye in each light filtering bar 141 to the material of the whole light filtering bar 141 gradually increases from two sides to the middle of the liquid crystal display panel.

The yellow dye is of a granular structure, the granular structure comprises cadmium yellow, oxygen yellow, silver colloid and the like, the particle size of the granular structure is 10-500 nm, the small molecular dye is uniformly dispersed in the glass, the yellow depth is adjusted by adjusting the proportion of the dye, and the absorption intensity of red light and green light is further changed.

The filter strip can be generally a whole made of cadmium yellow (CdS), oxygen yellow (CdO), bismuth vanadate (BiVO 4), lead silicate (PbSiO 3), iron oxide (Fe 2O 3), silver colloidal particle doped transparent glass layer; referring to fig. 1, 5 and 6, the light-filtering strip 141, under the influence of gravity, slides down to the position of the color-resisting layer 122 from the color-resisting wire 123 following the micro-gas spring 162, and faces the color-resisting layer 122 in the second area 220, so as to effectively absorb part of red light and green light, thereby reducing the red light and the green light, further keeping uniform with the blue light which penetrates through the light, and avoiding the yellow color after light mixing. Of course, the sub-shading strips are not integral, and can be formed by combining structures with different proportions of multi-segment yellow dyes.

Further, for each of the light filtering bars 141, the proportion of the yellow dye in the light filtering bar 141 on the side close to the input end of the gate line of the liquid crystal display panel 100 is greater than the proportion of the yellow dye in the light filtering bar 141 on the side far away from the input end of the gate line of the liquid crystal display panel, considering the loss problem of the gate signal, the loss on the side close to the input end of the gate line is smaller, so the pixel is charged more sufficiently, the actual brightness is closer to the target brightness, if the yellowing problem occurs here, the yellowing problem is observed by naked eyes more, the yellowing problem needs a sub-filter film segment with a higher yellow dye ratio to improve, and the corresponding sub-filter film segment is far away from the input end of the gate line, the actual brightness is greater than the target brightness, the darkening may occur, the yellowing problem here is not easily perceived by the naked eyes, and the light passing through the color blocking layer is also reduced here, so the sub-filter film segment with a lower color dye ratio is selected to improve; similarly, considering the problem of data voltage loss of the data line, the yellow dye ratio of the sub-filter can be controlled and improved at different positions away from the input end of the data line.

As shown in fig. 7, as a fifth embodiment of the present application, a further refinement of the foregoing embodiment is provided, where the filter film includes a plurality of light filtering bars 141, the plurality of light filtering bars 141 are arranged in a row in the first sub-region 221, and when the liquid crystal display panel is erected, along a gravity direction, a proportion of yellow dye in the light filtering bar 141 close to the first region 210 toward the light filtering bar 141 far from the first region 210 in the material of the whole light filtering bar 141 increases sequentially; the proportion of the yellow dye in the plurality of light filtering strips 141 to the material of the whole light filtering strip 141 is sequentially increased, and the width is kept unchanged, that is, the widths of all the light filtering strips 141 are equal to each other and are t; when the liquid crystal display panel is erected, along the direction of gravity, the proportion of the yellow dye in the first light filtering strip 141 in the corresponding first sub-region 221 to the material of the whole light filtering strip is the smallest, and the proportion of the yellow dye in the last light filtering strip 141 to the material of the whole light filtering strip is the largest; since the closer to the second sub-region 222, the more the liquid crystal is gathered, the thicker the liquid crystal is, the weaker the blue light is penetrating, and the more severe the yellowing is, the more yellow dye is in the corresponding filter stripe, and thus the more red and green light is absorbed.

Further, as shown in fig. 8, as a sixth embodiment of the present application, unlike the fifth embodiment, the widths of the plurality of light filtering bars 141 in the gravity direction are sequentially increased; specifically, in the direction of gravity, by way of example, three filter bars, a width t1 of the first filter bar 141 in the corresponding first sub-area 221 is smallest with respect to the other filter bars 141, for example, a width t2 of the second filter bar and a width t3 of the third filter bar, a width t3 of the last filter bar 141 is largest with respect to the other filter bars 141, the width of the three filter bars from top to bottom is in a relationship of t1 < t2 < t3, and the widths of the three filter bars may be sequentially increased by a fixed value, for example, t2-t1= t3-t2=1cm; or not at a fixed value, t2-t1=1cm, t3-t2=1.2cm; while increasing the yellow dye ratio, the width of the sub-filter strip 141 is further increased, so that the yellow dye ratio is wider than the larger filter strip 141, thereby further blocking the red light and the green light, and reducing the problem of yellow color bias.

As a seventh embodiment of the present application, as shown in fig. 9, considering that the most accumulated liquid crystal is near the middle of the second sub-area 222 in the first sub-area 221, the ratio of the yellow dye in the light filter strip to the material of the whole light filter strip in the first sub-area 221 sequentially increases from two sides of the first sub-area 221 to the middle, and correspondingly, the widths of the plurality of light filter strips sequentially increase from two sides of the first sub-area 221 to the middle.

Further, as shown in fig. 10, as an eighth embodiment of the present application, in consideration that the second sub-area 222 may also have a problem of liquid crystal aggregation, a light-filtering bar 141 may be disposed corresponding to the second sub-area 222, a ratio of the yellow dye in the light-filtering bar 141 to the material of the whole light-filtering bar increases from two sides of the second sub-area 222 to the middle, while a width of the light-filtering bar 141 in the corresponding first sub-area 221 remains unchanged, and a ratio of the yellow dye in the light-filtering bar 141 to the material of the whole light-filtering bar increases from two sides of the first sub-area 221 to the middle.

For any of the above embodiments, the width of the filter or the ratio of yellow dyes is mainly related to the number of liquid crystal aggregates and the corresponding cell thickness, and a filter with a high ratio of yellow dyes is required to be arranged in a place with a large cell thickness due to the large amount of liquid crystal aggregates in the display region, but the ratio of yellow dyes in the filter is not arranged from top to bottom and from two sides to the middle.

It should be noted that the inventive concept of the present application can form many embodiments, but the present application has a limited space and cannot be listed one by one, so that, on the premise of no conflict, any combination between the above-described embodiments or technical features can form a new embodiment, and after the embodiments or technical features are combined, the original technical effect will be enhanced.
