Description of the Invention: [Technical Field] The present invention relates to a display device, and more particularly to a display device having a repair circuit layout. [Prior Art] With the development of technology, electronic products have been filled with people's daily lives, and display devices have become an important medium for people to obtain information. Generally, a display device has a display panel for displaying information and a driving circuit for controlling the display panel. The driving circuit provides a data signal to the Pixel of the display panel through the data line, so that the display panel is in a plane. However, in the process of manufacturing the display device, the problem of data line disconnection often occurs, so that the display device is good. The rate drops. In order to solve the problem of data line disconnection, the prior art proposes a technique for repairing a broken line. Figure 丨 is a schematic diagram of a conventional display device with a repair circuit layout. Referring to FIG. 1, the display device 100 includes a first substrate Π0 and a second substrate 120, and the second substrate 120 has an amplifier 126. The first substrate no is, for example, a display panel. The second substrate 120 is, for example, a drive circuit board. The first substrate 11() includes a plurality of pixels 112. The second substrate 120 is provided with a data signal Vin to the pixel 112 of the first substrate 11 through a plurality of data lines (indicated by data lines 122 and 124). Assuming that the data line 122 is disconnected (in the figure i, χ, indicating the position of the broken line), the data line 122 can be divided into data lines 122Α and 122Β, 6 200834491 FU60434SEZ1TW 22S76twf.doc/n and the data signal Vin is only It can be transmitted to the data line 122A. In other words, the data line 122B cannot receive the data signal Vin. In order to enable the data line 122B to receive the data signal Vin, the prior art uses laser technology to provide another signal transmission path. The welding point M1 and the welding point M3 are respectively welded by the laser technology. Thus, the data signal vin can be sequentially transmitted to the data line 122B through the wire 122A, the fusion point M1, the amplifier 126, and the fusion point M3 to make the data The data (not shown) coupled to the line 122B can also present data. Fig. 2 is a schematic diagram of an equivalent circuit according to Fig. 1. Referring to Fig. 1 and Fig. 2, the terminal A can receive the data signal Vin. Since the two inputs of the amplifier 126 can be regarded as a virtual short, the end point b will also receive the data signal Vin. In addition, since the impedance between the end point b and the end point c is relatively small, the end point C The data signal Vout can be regarded as the same as the data signal Vin of the endpoint B. The data signal Vout=VinxZs/(Zr+Zs) of the endpoint D can be derived from the above, wherein the impedance Zr is between the endpoint c and the endpoint D. The wire impedance, impedance Zs is the impedance of the wire between the end point D and the wire break position, X". It is worth noting that although the prior art solves the disconnection problem, the impedance between the endpoint C and the endpoint D causes the signal to decay. The signal attenuation will make the signal (not shown) connected to the data line 122B unable to obtain the signal of sufficient intensity, so that the brightness and the ideal value displayed by the pixel (not shown) connected to the data line 122B will be There is a big gap, causing distortion in the face. If the signal V〇ut of the endpoint D can be more approximated to the signal of the endpoint a, the pixel π of the data line 122B can be greatly improved. 7 200834491 ^ut) U434b£ZlTW 22876twf.doc/n Brightness and The problem of inconsistent ideal values. In view of this, related manufacturers of display devices are not eager to find a suitable solution to overcome the above problems. FIELD OF THE INVENTION The present invention includes a first substrate 'second substrate, a first amplifier, and the present invention provides a display device having a repair circuit layout, which does not solve the problem of disconnection of the panel, and further reduces the signal due to attenuation. Distortion: The present invention is a display device having a repair circuit layout. With two ends. At the first end of the first feedback line, the flute is a green one. The second end of the first return line is coupled to the first input of the first finger, the green end of the first circuit.

For example, in another embodiment the number of drive circuits 330 can be one. Figure 3B is a schematic illustration of a pixel in accordance with a first embodiment of the present invention. Referring to FIG. 3A and FIG. 3B simultaneously, in the embodiment, the driving circuit 34 is exemplified by a scan driving circuit (Scan Drive Circuit), and the driving circuit 340 is transmitted through a plurality of scanning lines (here represented by scanning lines 342 and 344). A scan signal is provided to the Alizarin 302. Each of the halogens 302 includes, for example, a transistor 304, a storage capacitor 306, and a halogen capacitor 3〇8, as shown in Fig. 3B. The gate of the transistor 304 is coupled to the scan line 342, and the first source of the transistor 304 is coupled to the data line 332. One end of the storage capacitor is coupled to the second source drain of the transistor 304, and the second end of the storage capacitor 3〇6 is coupled to the first voltage. The first end of the halogen capacitor 3〇8 is coupled to the second source drain of the transistor 304, and the second end of the halogen capacitor 3〇8 is coupled to the second voltage. In short, the driver circuit 34 is used to provide a scan signal to the pixel 302. The embodiment of Fig. 3A is described with three drive circuits 34, but in other embodiments, the number of drive circuits 34 can be arbitrarily adjusted as needed. For example, the number of driving circuits 34A may be one. Referring to FIG. 3A, when the data line 334 is disconnected (the position of the disconnection is indicated by 'V in FIG. 3A), the data signal provided by the driving circuit 33〇 cannot be sent to the lower half of the data line 334. Lightly connected to each element 302. In order to enable the data signal to be transmitted to the respective elements 3G2 coupled to the lower half of the data line 334, this embodiment provides another path for transmitting data signals. For example, after confirming that the data line 334 is disconnected, the welding point M10 is first fused by the laser, and the preliminary line BU and the data line 11 200834491 rwu^^foEZlTW 22876twf.doc/n are mutually fused at the position where the teeth are connected. Thereby, the standby line and the data line 334 can be "passed" to each other, and the data signal provided by the driving circuit 33 can be sequentially input, the data f 334, the fusion point M10 and the preparatory line are input to the amplification 350. Input (positive input). In this embodiment, the laser beam technology is used as an example to weld the standby line Bk1 and the data line 334. However, those skilled in the art can change the implementation manner according to their needs. In other words, when the feed line 334 is broken, the first end of the data line 334 can be lightly connected to the first input of the amplifier 350 in any manner. In the above, the fusion splice point M12 is then welded to couple the repair line Ri〇 to the lower half of the bead line 334, but other suitable means may be used to couple the repair line R10 with the lower half of the data line 334. Pick up. In this way, the data signal provided by the driving circuit 330 can pass through the data line 334, the fusion point M10, the standby line Bk1, the amplifier 35〇, the repair line R1〇, the feedback line F10 and the fusion point M12 to reach the data line 334. Half of the problem solves the problem of the disconnection of the caution line. Referring again to FIG. 3A, the face-to-face relationship between the repair line R1 〇 and the feedback line F10 can be clearly seen from FIG. 3A. The first end of the repair line Ri is lightly connected to the output of the amplifier 350. The first end of the feedback line F10 is coupled to an input (negative input) of the amplifier 35〇. The second end of the feedback line F10 repairs the connection point of the line R10! ) is located on the first substrate 310. Those skilled in the art can also view their needs, and in accordance with the teachings of the present invention and the teachings of the foregoing embodiments, change the position of the connection point D1 so that the feedback signal of the amplifier 350 can be from the bottom half of the data line 334. The location of the department is returned. In this way, the advantage of reducing the attenuation of the signal can be obtained. 12 200834491 FU〇U4J4b£ZlTW 22876twf.doc/n In view of the above, FIG. 4 is a schematic diagram of the equivalent circuit of FIG. 3A. Please refer to FIG. 3A and FIG. 4 at the same time, and the terminal A1 in FIG. 4 can receive the data signal Vin. Since the two inputs of the amplifier 350 are virtual short circuits, the terminal Bi can also receive the data signal Vin. The impedance Zr represents the impedance of the repair line R1, the impedance Zf represents the impedance of the feedback line F10, the impedance Zs represents the impedance of the data line 334 from the fusion point M12 to the disconnection position, and x". It is assumed that the end point C1 The data signal is Vout, the data number passing through the connection point D1 is Vout, the current passing through the terminal C1 is ir, the current from the connection point D1 to the impedance Zs is Is, and the current from the connection point D1 to the impedance Zf is If. From the above, the pressure difference of the feedback line F10 (that is, the voltage difference of the impedance zf) Δ V=Vout-Vin=IfxZf can be derived, so v〇ut=Vin+IfxZf, and because the input end of the amplifier 350 is high impedance. Therefore, the current if is close to 〇, that is, Vout=Vin. In other words, in this embodiment, the position of the connection point D1 of the feedback line F1 〇 and the repair line R10 is disposed on the first substrate 31 采用. Therefore, the attenuation of the data signal can be greatly reduced. In this way, the signal attenuation can be avoided, and the disconnection position "x", the brightness of the pixel 302 connected to the lower data line 334 is insufficient. Those skilled in the art can also modify the number of amplifiers according to the spirit of the present invention and the teachings of the foregoing embodiments, and adjust the coupling relationship appropriately to repair a plurality of disconnection problems. For example, Figure 5 is a schematic illustration of a display device having a repair circuit layout in accordance with a second embodiment of the present invention. Referring to FIG. 5, the first substrate 310, the second substrate 32, the driving circuit 330, the driving circuit 340, the repair line R10, the feedback line F10, the data lines 332 to 336, the scan lines 342 and 344, the pixel 302, and the amplifier 13 200834491 FU6U434SEZ1TW 22 S7 6twf.doc/n 350 is the same as the above embodiment, and will not be described again here. It is worth noting that the amplifier 352, the standby line Bk3, the repair line and the feedback line F12 of this embodiment. When the above-mentioned guest wire 336 is also broken (in the figure of $, χ, , indicating the position of the wire break), the data signal provided by the drive circuit 33 盏 is sent to the lower half of the data line 336. The respective pixels coupled are 3〇2. In order to enable the data signal to be transmitted to the individual elements 302 coupled to the lower half of the data line 336, the present embodiment provides another path for transmitting data signals. For example, after the data line 336 is disconnected, the fusion point Μ 14 is fused by the laser, that is, the preliminary line Bk3 and the data line 336 are welded to each other at the floating position. Thereby, the standby line Bk3 and the data line 336 can be electrically connected to each other, and the data signal provided by the driving circuit 330 can be sequentially input to the first input end of the amplifier 352 via the data line 336, the fusion point M14 and the standby line Bk3. (positive input). In the above, the fusion splice point M16 is then melted to couple the repair line R12 and the lower half of the data line 336 to each other. In this way, the data signal provided by the driving circuit 330 can be passed to the lower half of the data line 336 via the data line 336, the fusion point M14, the preparation line Bk3, the amplifier 352, the repair line R12, and the feedback ρ6. The domain 2 = line 336 has a problem of disconnection, so that the pixel 302 coupled to the lower half of the data line 336 receives the data signal. Referring again to FIG. 5, the coupling relationship between the repair line R12 and the feedback line F12 can be clearly seen from FIG. The first end of the repair line R12 is coupled to the output of the amplifier 352. The first end of the feedback line F12 is coupled to the first input (negative input) of the amplifier 352 200834491 ruou^f^^EZlTW 22876twf.doc/n. The connection point D3 of the second end of the feedback line F12 and the repair line R12 is located on the first substrate 31A. It is worth noting that the closer the connection point D3 is to the data line where the disconnection occurs, the less the signal attenuation will be. Therefore, in this embodiment, the connection point D3 is designed on the first substrate 310 to reduce the attenuation of the data signal. Those skilled in the art can also change the coupling path of the repair line and the feedback line according to the spirit of the present invention and the teachings of the foregoing embodiments, and can appropriately change the arrangement position of the driving circuit. For example, Figure 6 is a schematic illustration of a display device having a repair circuit layout in accordance with a third embodiment of the present invention. Referring to FIG. 6, the first substrate 310, the second substrate 320, the driving circuit 330, the data lines 332 to 336, the scanning lines 342 and 344, the pixels 302, and the amplifier 350 are the same as those in the above embodiment, and are not described herein again. It is worth noting that the repair line R14, the feedback line F14, the driving circuit 340 and the third substrate 360 of this embodiment. In the above, the third substrate 360 will be described by taking a printed circuit board as an example. In other embodiments, the third substrate 360 can also be a flexible circuit board or other suitable substrate. In the present embodiment, the driving circuit 340 is disposed on a flexible circuit board that is connected between the first substrate 310 and the third substrate 360. The driving circuit 340 is configured to provide scanning signals to the scan lines 342 and 344 of the first substrate 310. In another embodiment, the drive circuit 340 can also be directly disposed on the third substrate 360. Moreover, the number of drive circuits 340 can also vary depending on their needs. For example, in another embodiment, the number of drive circuits 340 can be one. The impedance of the line formed on the printed circuit board (third substrate 360) 15 200834491 ruou^^oEZlTW 22876twf.doc/n will be smaller than the impedance of the line formed on the glass substrate (first substrate 310). Therefore, in order to improve the signal attenuation, the repair line R14 of the embodiment sequentially passes through the second substrate 320 and the third substrate 360 from the output end of the amplifier 350 to the first substrate 310. The feedback line fh sequentially passes through the second substrate 320 and the third substrate 360 from the negative input end of the amplifier 35〇 to the first substrate 310, and simultaneously fixes the connection point of the line ^^ and the feedback line ^^ On a substrate 310. In this way, the impedance of the repair line R14 and the feedback line F14 can be further reduced, thereby improving the data signal attenuation. Those skilled in the art can also change the configuration position of the amplifiers according to the teachings of the present invention and the teachings of the foregoing embodiments and adjust the light path of the standby line, the feedback line and the repair line as appropriate. For example, the amplifier 350 of the embodiment of Fig. 6 can be disposed on the third substrate 36A. For another example, the amplifier 350 of each embodiment can be integrated into the drive circuit 33A or the drive circuit 340. In summary, in the display device with the repair circuit layout of the embodiments of the present invention described above, the following advantages are obtained: I provide an alternate signal transmission path for transmitting data signals through the signal when the data line is disconnected. The transmission path is transmitted to the halogen element coupled below the data line break line to solve the problem of disconnection of the data line of the display device. 2. Arrange the feedback point of the amplifier on the substrate where the disconnection occurs, which reduces the distortion caused by the attenuation of the data signal. 3. The feedback line connected to the repair line of the amplifier output and the negative input of the amplifier should be formed as far as possible on the line of low-impedance material.
