BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a probe sheet for inspecting a liquid crystal display panel, and more particularly to a device such as a liquid crystal display panel that must repeatedly apply the same signal in several wiring units. The present invention relates to a probe sheet for inspecting a liquid crystal display panel that can be applied to a panel, a probe unit having the same, and a method for manufacturing a probe sheet for inspecting a liquid crystal display panel.

Generally, the process of manufacturing a liquid crystal display includes the inspection process which sorts the good goods of a liquid crystal display panel.

The drive module is attached to the panel determined as good in the inspection process. The inspection process is a process of monitoring an operating state of a panel by transmitting an electrical signal to a portion to which the driving module is attached. In this case, a probe unit electrically connected to the panel is installed.

In order to inspect the pixels of the panel during the inspection process, a pattern of six color signals of the same R, G, B, R ', G', and B 'is repeatedly applied to the input part of the panel to inspect the pixels of the panel. There is a way. To this end, as shown in FIG. 1, the above six color signals are transmitted as a set for every six patterns 11 of the panel 10 at the portion where the driving module (not shown) is attached. Get the output status and check it.

In the inspection process of this method, referring to FIG. 1, the probe unit used to inspect the pixels of the panel 10 is manufactured for the purpose of transmitting six color signals to the panel. 1 is a conceptual diagram illustrating a concept of transmitting six color signals to a panel 10 in the related art. In order to transmit six color signals to a large number of patterns 11 of the panel 10, FIG. As shown, a large number of transmission lines must be formed in each of the patterns 11 from six color signals. And, until now, as a way to solve this problem by forming a cross wiring through the film 20 having a double-sided wiring as shown in Figure 2 using a needle or blade type probe unit as the contact means 30 color A method of transmitting signals to the panel was used.

As shown in FIG. 2, conventionally, the contact means 30 has a blade-like structure, one end of which is in contact with the pattern 11 of the panel 10 and the other of which the color signals R, G formed in the film 20. It is in contact with a transmission line (pattern) for transmitting signals such as B, R ', G', and B '. Here, the color signal to the film 20 is transmitted from the flexible circuit board FPCB connected to the film 20 oppositely to which the contact means 30 is attached.

In addition, since the contact means 30 and the shorting sheet 20 are made of a contact rather than an adhesive, the probability of an error occurring between the contact means 30 and the shorting sheet 20 is increased, and the LCD display panel 10 is inspected. There is a problem that many inspection errors occur

When the first wiring sets 510 are formed on one surface of the sheet body 110, an insulating material may be applied to one surface of the sheet body 110 except for the predetermined region, or the insulating cover tape may be adhered thereto. It may be.

[Formation of Output 230]

The output unit 230 is formed by exposing one end of the first wiring sets 510 positioned at one side of the seat body 110 to the outside. Since the output unit 230 is a portion in direct contact with the pattern formed on the panel to be tested, the output unit 230 is formed at one end of the first wiring region 200 of the sheet body 110.

The output unit 230 may also be formed to expose the outside by forming a predetermined area to have the same pitch as the pattern of the panel to be inspected, and in this case, the first wiring sets 510.

That is, in a state where the sheet body 110 forms a plane, the wiring connection area 400 is folded based on the folding boundary F so that the second junction part 310 is joined to the first junction part 210. Thus, the seat body 110 according to the present invention can achieve the state shown in FIGS. 4 and 5.

In this case, while the wiring connection area 400 according to the present invention is folded about the folding boundary F, the third wiring sets 530 in the wiring connection area 400 cross each other but are covered by a film. Therefore, it is insulated from each other.

Therefore, in the probe sheet 100 manufactured as described above, the color of the wiring set of any one of the first wiring sets 510 exposed to the outside through the input unit 220 formed in the first wiring region 200. When the signal is input, the color signal is transmitted to the second wiring set 520 of the second wiring region 300 through the third wiring set 530 of the wiring connection region 400. In addition, the six color signals transmitted are electrically connected to the second junction 220 of the second wiring set 520 by being bonded to the first junction 210, and thus, the first wiring again through the first junction 210.

Referring to the drawings, in FIG. 3, six color signals from the upper part of the first wiring set 510 to the input part 220 of the first wiring set 510 are formed from the top of the first wiring region 200. When 6 is inputted, the six wires included in the second second wiring set 520 from the upper portion of the second wiring region 300 through the third wiring set 530 connected to the first first wiring set 510. Four color signals are transmitted.

At this time, when the second wiring region 300 is folded based on the folding boundary F, the wirings of the second second wiring set 520 from the top are electrically connected to the wirings of the second first wiring set 510 from the top. do. Then, six color signals are also transmitted to the second first wiring set 510 from above. In this manner, six color signals are repeatedly input to each of the first wiring sets 510 existing in the first wiring region 200. Six color signals repeated through the output unit 230 formed at one end of the first wiring region 200 are output to the outside. The input of the color signals may be input by the flexible circuit board 150 (shown in FIG. 6) connected to the input unit 220.

3 and 5, when the number of sets of the first and second wiring sets 510 and 520 is n (the natural number), the number of sets of the third wiring sets 530 is n−1.

Accordingly, the first, second, third, fourth, fifth, fifth, and fifth of the first set of wirings 510, the first set of wirings 510 of the first wiring region 200 exposed to the outside through the input unit 220, are exposed. When the six color signals R, G, B, R ', G', and B 'signals are sequentially input to the six wires, the R color signal input to the first wire is set to No. 1 third wire set 530. R color signal transmitted through the first 'wiring' and the first 'wiring' are transmitted through the first " wiring of the second set of second wirings 520, and the R color transmitted through the first " wiring The signal is transmitted from the first junction 210 coupled to the second junction 310 to the first interconnection of the second wiring set 510 arranged at the lower end of the uppermost end to be externally connected through the output 230. Can be output as

The R color signal transmitted to the first wiring of the second wiring set 510 is the first wiring of the first wiring set 510 that is arranged below the second wiring set 510. It can be transmitted in the above manner.

In addition, the remaining G, B, R ', G', B 'signals may be transmitted in the same manner as described above and output to the outside through the output unit 230 as shown in FIG.

As described above, in the present invention, the first and

second wiring regions

200 and 300 and the wiring connection region 400 connecting the first and

second wiring regions

200 and 300 are formed in the sheet body 110 in the same layer. In addition, the second connection part 310 formed at the end of the second wiring area 300 by folding the wiring connection area 400 is bonded to the first connection part 210 formed in the first wiring area 200 and electrically connected thereto. When a color signal is input to any one of the plurality of first wiring sets 510, it may be output to the outside through an output unit 230 formed at one end of all the first wiring sets 510. Can be.

Here, the bonding between the first junction 210 and the second junction 310 includes physical contact, and a method such as ultrasonic welding may be used.
