Detailed Description
In the following description, for purposes of explanation, numerous implementation details are set forth in order to provide a thorough understanding of the various embodiments of the present invention. It should be understood, however, that these implementation details are not to be interpreted as limiting the invention. That is, in some embodiments of the invention, such implementation details are not necessary.
In addition, for the sake of simplicity, some conventional structures and elements are shown in the drawings. Also, unless otherwise indicated, like reference numerals may be used to identify corresponding elements in the various drawings. The drawings are for clarity of understanding, and do not show actual dimensions of the elements.
Referring to fig. 1 to 3, fig. 1 is a cross-sectional view of a display panel according to the present invention, and fig. 2 and 3 are schematic structural views of a color filter before and after being cut.
As shown in fig. 1, the display panel 10 of the present invention includes a color filter 100, a tft array substrate 200 and a sealant 300, wherein the sealant 300 is disposed between the color filter 100 and the tft array substrate 200. The thin film transistor array substrate 200 includes an array substrate body 210 and a thin film transistor layer 220 attached to the array substrate body 210.
Before cutting, as shown in FIG. 2, a plurality of color filters 100 are formed on a whole plate. Referring to fig. 1 again, the color filter 100 includes a substrate body 110, a black matrix layer 120, a first color layer 130, a second color layer 140, a third color layer 150, a protection layer 160, and a cut alignment mark 170 (see fig. 2). During cutting, alignment is performed according to the cutting alignment mark 170 to ensure cutting accuracy. By cutting the alignment mark 170 to align, a single color filter 100 as shown in FIG. 3 is formed after cutting along the cutting line (dotted line in FIG. 2) shown in FIG. 2.
The black matrix layer 120 is disposed on the substrate body 110, and the substrate body 110 has a display region 110a and a peripheral region 110b (as shown in fig. 3). In the present embodiment, the first color layer 130 is located in the display area 110a and the peripheral area 110b of the substrate body 110, the second color layer 140 and the third color layer 150 are respectively located in the display area 110a of the substrate body 110, and the protection layer 160 covers the black matrix layer 120, the first color layer 130, the second color layer 140 and the third color layer 150 located in the display area 110a of the substrate body 110. The dicing alignment mark 170 is located in the peripheral region 110b of the substrate body 110.
In the present embodiment, the first color layer 130, the second color layer 140, and the third color layer 150 are a blue color layer, a red color layer, or a green color layer, respectively, but the invention is not limited thereto, and different colors can be used to match according to different display requirements.
As shown in fig. 3, the color filter 100 of the embodiment of the invention further includes a blocking structure 180, and the blocking structure 180 is disposed in the peripheral region 110b of the substrate body 110. Referring to fig. 4a and 4b, fig. 4a and 4b are schematic diagrams illustrating a blocking structure of a color filter according to a first embodiment of the present invention. The blocking structure 180 includes a first layer structure 181 and a second layer structure 182, and the first layer structure 181 is located between the peripheral region 110b of the substrate body 110 and the second layer structure 182, in other words, the first layer structure 181 is disposed on the peripheral region 110b of the substrate body 110, and the second layer structure 182 is stacked on the first layer structure 181. In the embodiment, the barrier structure 180 formed by the first layer structure 181 and the second layer structure 182 has a step shape with a certain thickness.
In detail, since the first layer structure 181 is disposed on the peripheral region 110b of the substrate body 110, and the second layer structure 182 is stacked on the first layer structure 181, that is, the cross sections of the layers are not in the same horizontal plane, the blocking structure 180 composed of the first layer structure 181 and the second layer structure 182 has a certain height difference with respect to the surface S of the peripheral region 110b of the substrate body 110, so as to have a certain thickness. In addition, the first layer structure 181 and the second layer structure 182 have different areas, and thus form a "step shape".
Referring to fig. 4a and 4b, the dicing alignment mark 170 is disposed on the surface of the blocking structure 180, that is, the dicing alignment mark 170 is disposed on the second layer 182 of the blocking structure 180.
As shown in fig. 1 and 2, after the glue frame 300 is coated, the glue frame 300 is a boundary between the display area 110a and the peripheral area 110b of the substrate body 110. Since the overflow phenomenon of the rubber frame 300 occurs at the corner of the rubber frame 300 (e.g., a position in fig. 2) during the pressing process, the cut alignment mark 170 and the blocking structure 180 are also disposed at the corner of the substrate body 110 of the color filter substrate 100 (e.g., a position B in fig. 2). Because the blocking structure 180 is in a step shape with a certain thickness, the blocking structure 180 can prevent the overflowing glue frame 300 from shielding the cutting alignment mark 170, thereby ensuring the cutting precision during cutting, being beneficial to increasing the qualification rate of the display panel, and avoiding the subsequent process of overflowing glue.
Specifically, with reference to fig. 2, fig. 3, fig. 4a and fig. 4b, the blocking structure 180 composed of the first layer structure 181 and the second layer structure 182 has a certain thickness D, and can block the overflow of the rubber frame 300 at the position a during pressing, and the first layer structure 181 and the second layer structure 182 form a step topography SP due to different areas, so that the rubber frame 300 is easy to stay at the step topography SP during pressing or be accommodated at the step topography SP, thereby further preventing the overflow of the rubber frame 300.
Preferably, the height of the blocking structure 180 is 5um to 10um, so that it reaches a certain thickness to prevent the rubber frame 300 from overflowing. In detail, the height of the top surface of the matrix structure 180 from the surface S of the substrate body 110 is 5um to 10um, that is, the cutting alignment mark 170 is 5um to 10um from the surface S of the substrate body 110 (as shown in fig. 1).
In the first embodiment, the first layer structure 181 of the barrier structure 180 is made of the same material as the black matrix layer 120, and the second layer structure 182 is made of the same material as the first color layer 130.
That is, when the color filter 100 is manufactured, the black matrix layer 120 is formed in the display region 110a of the substrate body 110, and the first layer structure 181 of the blocking structure 180 is formed in the peripheral region 110b of the substrate body 110 by the black matrix layer 120. When the color filter 100 forms the first color layer 130 in the display region 110a of the substrate body 110, the first color layer 130 forms the second layer structure 182 stacked on the first layer structure 181 of the blocking structure 180 in the peripheral region 110b of the substrate body 110. As such, in the first embodiment, the barrier structure 180 is formed by stacking two layers.
As shown in fig. 5a and 5b, fig. 5a and 5b are structural diagrams of a blocking structure of a color filter according to a second embodiment of the present invention. In the second embodiment, the barrier structure 180' further includes a third layer structure 183 besides the first layer structure 181 and the second layer structure 182, and the second layer structure 182 is located between the first layer structure 181 and the third layer structure 183.

When the color filter 100 forms the first color layer 130 in the display region 110a of the substrate body 110, the first color layer 130 forms the second layer 182 stacked on the first layer 181 of the blocking structure 180' in the peripheral region 110b of the substrate body 110. When the color filter 100 forms the second color layer 140 in the display region 110a of the substrate body 110, the second color layer 140 forms the third layer 183 stacked on the second layer 182 of the blocking structure 180' in the peripheral region 110b of the substrate body 110. As such, in the second embodiment, the blocking structure 180' is formed by stacking three layers.
As shown in fig. 6a and 6b, fig. 6a and 6b are structural diagrams of a blocking structure of a color filter according to a third embodiment of the present invention. In the third embodiment, the barrier structure 180 ″ further includes a fourth layer structure 184 in addition to the first layer structure 181, the second layer structure 182, and the third layer structure 183 is located between the second layer structure 182 and the fourth layer structure 184. In the present embodiment, the material of the first layer structure 181 of the blocking structure 180 ″ is the same as that of the black matrix layer 120, the material of the second layer structure 182 is the same as that of the first color layer 130, the material of the third layer structure 183 is the same as that of the second color layer 140, and the material of the fourth layer structure 184 is the same as that of the third color layer 150.

When the color filter 100 forms the first color layer 130 in the display region 110a of the substrate body 110, the first color layer 130 forms the second layer 182 stacked on the first layer 181 of the blocking structure 180 ″ in the peripheral region 110b of the substrate body 110. When the color filter 100 forms the second color layer 140 in the display region 110a of the substrate body 110, the second color layer 140 forms the third layer 183 stacked on the second layer 182 of the blocking structure 180 ″ in the peripheral region 110b of the substrate body 110. When the color filter 100 forms the third color layer 150 in the display region 110a of the substrate body 110, the third color layer 150 forms a fourth layer 184 stacked on the third layer 183 of the blocking structure 180 ″ in the peripheral region 110b of the substrate body 110. Thus, in the third embodiment, the barrier structure 180 ″ is formed by stacking four layers.
As shown in fig. 3, 7a and 7b, fig. 7a and 7b are structural diagrams of a fourth embodiment of a blocking structure of a color filter of the present invention, and fig. 3 shows a top view of the fourth embodiment of the blocking structure applied to the color filter. In the fourth embodiment, the barrier structure 180' ″ further includes a fifth layer structure 185 in addition to the first layer structure 181, the second layer structure 182, the third layer structure 183, and the fourth layer structure 184 is located between the third layer structure 183 and the fifth layer structure 185. In the present embodiment, the material of the first layer structure 181 of the blocking structure 180' ″ is the same as that of the black matrix layer 120, the material of the second layer structure 182 is the same as that of the first color layer 130, the material of the third layer structure 183 is the same as that of the second color layer 140, the material of the fourth layer structure 184 is the same as that of the third color layer 150, and the material of the fifth layer structure 185 is the same as that of the protection layer 160.
That is, when the color filter 100 is manufactured, the black matrix layer 120 is formed in the display region 110a of the substrate body 110, and the first layer structure 181 of the blocking structure 180' ″ is formed in the peripheral region 110b of the substrate body 110 by the black matrix layer 120. When the color filter 100 forms the first color layer 130 in the display region 110a of the substrate body 110, the first color layer 130 forms the second layer 182 stacked on the first layer 181 of the blocking structure 180' ″ in the peripheral region 110b of the substrate body 110. When the color filter 100 forms the second color layer 140 in the display region 110a of the substrate body 110, the second color layer 140 forms a third layer structure 183 stacked on the second layer structure 182 of the blocking structure 180' ″ in the peripheral region 110b of the substrate body 110. When the color filter 100 forms the third color layer 150 in the display region 110a of the substrate body 110, the third color layer 150 forms a fourth layer 184 stacked on the third layer 183 of the blocking structure 180' ″ in the peripheral region 110b of the substrate body 110. When the color filter 100 forms the protection layer 160 in the display region 110a of the substrate body 110, the protection layer 160 forms a fifth layer structure 185 stacked on the fourth layer structure 184 of the blocking structure 180' ″ in the peripheral region 110b of the substrate body 110. As such, in the fourth embodiment, the barrier structure 180' ″ is formed by stacking five layers.
In the above embodiments, the structures of the respective layer structures may be the same. Preferably, the layers of the barrier structure 180(180 ', 180 "') have a cross-sectional area larger than that of the former layer in the order from the near to the far from the substrate body 110, i.e., in the order of the first layer structure 181, the second layer structure 182, the third layer structure 183, the fourth layer structure 184, and the fifth layer structure 185. It can also be said that the orthographic projection of the latter layer of structures lies entirely within the cross-section of the former layer of structures.
In the above embodiments, the dicing alignment mark 170 is located on the layer structure of the barrier structure 180 farthest from the substrate body 110. The cutting alignment mark 170 may be a groove structure or a protrusion structure formed on the surface of the barrier structure 180, or may be a planar structure having a marking function. Since the color filter 100 is at a right angle, the dicing alignment marks 170 at the corners are also at a right angle (the cross shape is shown by splicing with the adjacent dicing alignment marks before dicing).
In the above embodiments, each layer of the barrier structure 180 is in a right-angle structure, in other words, the barrier structure 180 includes the first barrier structure portion 180a and the second barrier structure portion 180b, and as an example, in the fourth embodiment shown in fig. 3, fig. 7a and fig. 7b, the first barrier structure portion 180a extends along a first direction D1, and the second barrier structure portion 180b extends along a second direction D2. Wherein the first blocking structure portion 180a and the second blocking structure portion 180b intersect and form an anti-spill corner 180 c. The first direction D1 is substantially perpendicular to the second direction D2. The anti-overflow corner 180c is located at the position a where the glue frame 300 is easy to overflow and scatter, and can effectively prevent the glue frame 300 from overflowing and shielding the cutting alignment mark 170.
The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
