Then, the substrates 110 and 120 are cut by using the cutting wheel 210 illustrated in
The method for cutting the mother panel 100 in the direction of the X axis is as follows. The cutting wheel 210 has different dispositions and ways of cutting at the non-aligned sides 310A and the aligned sides 310B. At the non-aligned sides 310A, two cutting wheels 210 which are disposed in a staggered way are used at the same time for cutting the substrates 110 and 120. Herein a set of cutting wheels 210 which are vertically staggered is used for respectively cutting the substrates 120 and 110 at the same time along the cutting lines 310A1 and 310A2. In addition, at the aligned sides 310B, a set of cutting wheels 210 which are also vertically staggered is used for cutting the substrates 110 and 120 at the same time along the aligned sides 310B. As shown in
The method for cutting the mother panel in the direction of the Y axis is as follows. The vertical cutting directions 320 are also categorized into non-aligned sides 320A and aligned-sides 320B. In the direction of the Y axis, the substrates 110 and 120 are cut at the same time along the vertical cutting directions 320. To be specific, at the non-aligned sides 320A, two sets of cutting wheels 210 which are disposed in a staggered way are used at the same time for cutting the mother panel 100. Herein a set of cutting wheels 210 which are vertically staggered is used for cutting the substrates 120 and 110 at the same time along the cutting lines 320A1 and 320A2. In addition, at the aligned-sides 320B, a set of cutting wheels 210 which are vertically staggered is used for cutting the substrates 110 and 120 at the same time along the aligned-sides 320B. As shown in
After the cutting process is complete, as shown in
Even though less residual material RE is left by arranging the panels 130 by the method described above, the removal regions R on the color filter substrate 110 are set in the mother panel 100a therefore are difficult to remove. Because the removal regions R cannot be detected precisely, it is difficult to remove them by using a suction device. As a result, a problem of an abnormal edge appearance is caused during a subsequent edge grinding process. In addition, when the color filter substrate 110 is moved before the removal regions R are removed, the removal regions R may drop onto the mother panel 100a and accordingly fragments of the removal regions R may be produced.
Accordingly, the present disclosure is directed to a panel fabricating method, wherein residual materials and removal regions on a color filter substrate can be removed at the same time.
The present disclosure is also directed to a panel fabricated by the aforementioned panel fabricating method, wherein the use efficiency of a material and the fabrication yield of the panel are both improved.

Then, a second substrate 420 is provided. The second substrate 420 has at least two second units 422 that are also arranged along the first direction D1, wherein each of the second units 422 has a second display region 422a and a removal region 422b sequentially arranged along the first direction D1. The second substrate 420 may be a color filter substrate.
Next, referring to both
After that, referring to
The cutting process is explained below in detail as follows. It should be noted that in
Referring to
In particular, the second substrate 420 is discontinuously cut along the cutting line CY3 by jump cutting, so as to form the discontinuous cut portion RS. Meanwhile, the first substrate 410 is continuously cut. The discontinuous cut portion RS is overlapped and connected with the removal region 422b of the second substrate 420 (the portion not indicated by bold lines).
Accordingly, the removal region 422b is connected with the residual material RE by the discontinuous cut portion RS. The removal region 422b connected with the discontinuous cut portion RS can be easily removed at the same time when the residual material RE is removed. In other words, because the removal region 422b of the second substrate 420 is not set between two adjoining panels 400 by itself, the problem of abnormal edge appearance in subsequent edge grinding process caused by un-removed removal region 422b is resolved.
Referring to
As described above, the panel fabricating method increases the material use efficiency and can be adopted for cutting more panels 410. In particular, because the removal region 422b is connected to the residual material RE by the discontinuous cut portion RS, the removal region 422b on the second substrate 420 can be easily removed by the residual material RE. Thus, related problems (for example, chippings and torn edges) caused by the difficult removal of the removal region 422b on the second substrate 420 can be resolved.
To be specific, besides performing a continuous cutting along the cutting lines CY1-CY3 and CX2 using a double-sided feed, in the present embodiment, the second substrate 420 is cut by jump cutting along the cutting line CX1 to form the discontinuous cut portion RS. The portions that are cut along the cutting line CX1 are indicated by the bold lines in
Referring to
Similarly, the extension length LX of the discontinuous cut portion RS is between 100 μm and 1,000 μm. Similar to that described in the first embodiment, the panel 400 can be effectively separated without being damaged at the discontinuous cut portion RS by the setting of the extension length LX.
The extension length LY of the discontinuous cut portion RS1 in the first direction D1 is between 100 μm and 1,000 μm, and the extension length LX of the discontinuous cut portion RS2 in the second direction D2 is between 100 μm and 1,000 μm. The panel 400 can be effectively separated without being damaged at the discontinuous cut portions RS1 and RS2.
In summary, the discontinuous cut portions RS, RS1, and RS2 are formed on the second substrate 420 by jump cutting, so that the removal region 422b on the second substrate 420 can be removed by the discontinuous cut portions RS, RS1, and RS2. The arrangement of the panels 400 in the first, second, and third embodiments described above is only an example but not intended to limit the present disclosure. The panels 400 may also be closely disposed along the horizontal direction X (not shown), and two adjacent rows of panels 400 are separated by the residual material RE in the vertical direction Y. The arrangement, cutting direction, and transmitting direction of the panels 400 may be determined by those having knowledge in the art according to the actual requirement of an actual application. It is within the scope of the present disclosure as long as the discontinuous cut portion RS is formed by jump cutting.

However, when the mother panel is cut by the method provided by the present disclosure to obtain the panels 400, a jump cutting operation is performed at the discontinuous cut portions RS, RS1, and RS2. Thus, the cutting surface S2 has no rib mark M at the discontinuous cut portions RS, RS1, and RS2.
To be specific, referring to
The area on the panel 400 that has no rib mark M varies with different dispositions of the discontinuous cut portions RS, RS1, and RS2 as illustrated in
The first substrate 510 may be an active device array substrate, and the active device array substrate includes a scan line and a data line (not shown), a plurality of active devices (not shown), and a plurality of pixel electrodes (not shown). The active devices are electrically connected to the scan line and the data line. The pixel electrodes are electrically connected to the drains of the active devices. The active devices may be thin film transistors (TFTs). The active device array substrate is well known by those having ordinary knowledge in the art and, therefore, is not described herein.
The second substrate 520 may be a color filter substrate, and the color filter substrate includes a transparent substrate (not shown), a color filter layer (not shown), and a common electrode (not shown). The color filter layer is disposed on the transparent substrate. The common electrode is disposed on the color filter layer. Because the color filter substrate is well known by those having ordinary knowledge in the art the color filter substrate is not described herein. In addition, the display panel structure 500 may further include a liquid crystal layer 530 disposed between the first substrate 510 and the second substrate 520.
The display panel structure 500 may adopt a panel 400 fabricated by a method provided by foregoing first, second, or third embodiments. It should be noted that only a part of the second side 520a of the display panel structure 500 has rib marks M, and the part having no rib mark M corresponds to the discontinuous cut portions RS, RS1, and RS2 in the first, second, or third embodiments. It can be determined that the panel adopted by the display panel structure 500 is fabricated by the panel fabricating method in the present disclosure when only a part of the display panel structure 500 has the rib marks M.
In summary, the panel fabricating method, panel, and display panel structure provided by the present disclosure have at least the following advantages.
Discontinuous cut portions are formed on the second substrate by jump cutting, and the removal region on the second substrate between two adjacent panels is removed by the discontinuous cut portions. Thus, problems in subsequent process caused by un-removed removal regions on the second substrate can be resolved. By fabricating panels and display panel structures by the panel fabricating method described above, the material cost is reduced, the use efficiency of the mother panel is improved, and the fabrication yield of the panels is increased.

In view of the foregoing, it is intended that the present disclosure cover modifications and variations of this disclosure provided they fall within the scope of the following claims and their equivalents.
