Although not illustrated in the drawing, the TFT panel 231 includes a plurality of pixels, and each pixel includes a photodiode and a thin film transistor to detect incident light and convert the visible light into an electrical signal. do.

The scintillator panel 232 includes an aluminum plate 232b and a scintillator layer 232a provided on the aluminum plate 232b so that the photodiode can detect X-rays incident from the outside. It converts to.

In this case, the aluminum plate 232b functions as a reflecting plate for directing the visible light converted from the scintillator layer 232a toward the TFT panel 231, and the scintillator layer 232a may be a CsI or the like. It is made of a material that converts X-rays into visible light.

At this time, the large area digital sensor panel 230 is manufactured by bonding the TFT panel 231 and the scintillator panel 232.

The manufacturing method of the large-area digital sensor panel 230 will be briefly described. A curable sealant 260 is applied to an edge of the TFT panel 231 or the scintillator panel 232, and the TFT panel 231 and the scintilla After bonding the radar panel 232, the large area digital sensor panel 230 is manufactured by curing the curable sealant 260 with ultraviolet or heat.

In this case, in the related art, an adhesive layer is provided between the TFT panel 231 and the scintillator panel 232, but in the first embodiment of the present invention, an adhesive is formed between the TFT panel 231 and the scintillator panel 232. No layer is formed which forms the layer.

The carbon black plate 240 blocks visible light incident from the outside while transmitting X-rays incident from the outside, such that only visible light converted by the scintillator panel 232 is incident on the TFT panel 231. Play a role.

3A illustrates a large area digital sensor panel according to a second embodiment of the present invention.

In the second embodiment of the present invention, the scintillator panel 332 including the TFT panel 331, the scintillator layer 332a, and the aluminum plate 332b includes the TFT panel 231 described in the first embodiment of the present invention. Since it is the same as the scintillator panel 232 which consists of the scintillator layer 232a and the aluminum plate 232b, the overlapping description is abbreviate | omitted below.

Referring to FIG. 3A, a large area digital sensor panel 330 according to a second embodiment of the present invention includes a TFT panel 331, a scintillator panel 332, and an adhesive layer 333.

The adhesive layer 333 serves to bond the TFT panel 331 and the scintillator panel 332.

In addition, the adhesive layer 333 is formed of an adhesive layer 333 having a uniform thickness by spraying a portion of the adhesive layer 333 with a liquid or gel adhesive 360 on the front surface of the TFT panel 331 instead of being sprayed on a portion thereof.

3B and 3C illustrate a method of manufacturing the large-area digital sensor panel 330 according to the second embodiment of the present invention.

Referring to FIG. 3B, the manufacturing method of the large area digital sensor panel 330 according to the second exemplary embodiment of the present invention is first provided so that the front surface of the TFT panel 331 forms a constant angle with a horizontal plane in space.

In the second embodiment of the present invention, the adhesive 360 is provided vertically so that the adhesive 360 flows down well from the top of the front of the TFT panel 331.

Subsequently, the adhesive 360 is sprayed onto the front surface of the TFT panel 331 by using the adhesive injector 350. In addition, the front edge of the TFT panel 331 is provided with a bonding portion protection jaw 340 so that the adhesive 360 is not applied to the edge.

The reason is that the general TFT panel 331 has an outer bonding portion (Outline bonding) for connecting external substrates (not shown) to a predetermined portion of the front edge, when the adhesive 360 is applied to the bonding portion, This is because connection or replacement of external substrates (not shown) is not easy.

In addition, although the bonding portion protection jaw 340 is illustrated to cover the entire front edge of the TFT panel 331, the bonding portion protection jaw 340 may be provided to cover only the portion where the bonding portion is formed.

Subsequently, the adhesive 360 sprayed on the top of the front of the TFT panel 331 flows down to the bottom of the front of the TFT panel 331 by gravity so that the adhesive 360 is formed on the front of the TFT panel 331. It is formed of an adhesive layer 333 of a constant thickness.

That is, the process is simpler than the conventional method of moving the adhesive injector 350 and applying the adhesive 360 to the front of the TFT panel 331, and uniformity because the adhesive 360 flows down by gravity. It is easy to form the adhesive layer 333 of one thickness.

At this time, the adhesive layer 333 is sprayed with the adhesive 360 to have a thickness of 10 ㎛ to 40 ㎛.

Subsequently, the TFT panel 331 is laid on the inside of the vacuum chamber with the adhesive layer 333 upward, and one side lower portion of the scintillator panel 332 is in contact with an upper portion of the adhesive layer 333. The roller 370 is positioned on an upper side of the scintillator panel 332.

In this case, the lower surface of the scintillator panel 332 is in close contact with the upper surface of the adhesive layer 333 by rotating and moving the roller 370 while being in contact with the upper portion of the scintillator panel 332.

Subsequently, the adhesive layer 333 is cured and the TFT panel 331 and the scintillator panel 332 are adhered by the adhesive layer 333 to manufacture a large area digital sensor panel 330.

In the above-described manufacturing method of the large-area digital sensor panel 330, the step of bonding the scintillator panel 332 onto the TFT panel 331 on which the adhesive layer 333 is formed may be performed in the vacuum chamber ( 380 may be carried out by a vacuum compression method.

Referring to FIG. 3C, first, a TFT panel 331 having an adhesive layer 333 is placed on a first support table 381 provided in the vacuum chamber 380 with the adhesive layer 333 upward, and the scintillator panel Reference numeral 332 is positioned above the TFT panel 331 using the second support table 382.

The second support table 382 has a hole for transmitting pressure in a lower portion thereof, and a cavity connected to the hole in the lower portion of the second support table 382. A vacuum chuck capable of sucking the scintillator panel 332 is provided.

However, the second support table 382 may be provided as an electrostatic chuck pulling the scintillator panel 332 due to an electrostatic phenomenon.

Subsequently, the inside of the vacuum chamber 380 is vacuumed using a second vacuum pump (not shown).

Then, the second support table 382 is lowered until the distance between the TFT panel 331 and the scintillator panel 332 becomes a constant distance.

At this time, the second support table 382 is lowered until the distance between the TFT panel 331 and the scintillator panel 332 is between 5 mm and 10 mm. The reason is to freely drop the scintillator panel 332 in a vacuum so that the scintillator panel 332 is in uniform contact with the adhesive layer 333.

On the other hand, the second support table 382 is lowered by using a moving bar 384, which is formed with a screw on the outside of the motor 383 and moves up and down by the rotation of the motor.

However, the motor 383 can be any means as long as it can move the second support table 382 up and down, such as a hydraulic actuator, a pneumatic actuator.

Subsequently, the pressure inside the second support table 382 is released, and the scintillator panel 332 freely falls to contact the scintillator panel 332 with the adhesive layer 333.

The second support table 382 is lowered to physically apply pressure to the scintillator panel 332 so that the scintillator panel 332 is in uniform contact with the adhesive layer 333.

Subsequently, the vacuum inside the vacuum chamber 380 is released by a purging means so that the TFT panel 331 and the scintillator panel 332 are vacuum compressed.

In addition, the purging means (not shown) is nitrogen purging means for increasing the internal pressure of the vacuum chamber 380 by introducing nitrogen into the vacuum chamber 380.

At this time, the step of physically applying pressure to the scintillator panel 332 by lowering the second support table 382 may be reversed.

Therefore, since the second support table 382 is lowered and the pressure is applied once, and the pressure is applied again by nitrogen purging, the adhesion between the TFT panel 331 and the scintillator panel 332 can be improved. There is.

Example 3

4A and 4B are cross-sectional views and a plan view illustrating a large area digital sensor panel 230 according to a third embodiment of the present invention.

In the third embodiment of the present invention, the scintillator panel 432 including the TFT panel 431 and the scintillator layer 432a and the aluminum plate 432b is the TFT panel 231 described in the first embodiment of the present invention. And the same as the scintillator panel 232 formed of the scintillator layer 232a and the aluminum plate 232b, and thus redundant description thereof will be omitted below.

Referring to FIGS. 4A and 4B, the large-area digital sensor panel 430 includes a scintillator panel 432, a TFT panel 431, and an edge portion at which visible light cannot be sensed by the TFT panel 431. And a bonding layer 433b formed in the dam 433a and the dam 433a to bond the scintillator panel 432 to the TFT panel 431.

The dam 433a is formed of a first thermosetting material such as a first thermosetting material or a first UV-curable material having a high viscosity at an edge portion of the TFT panel 431 which cannot sense visible light, and is formed by heat or UV. After curing, the scintillator layer 432a of the scintillator panel 432 is protected from moisture in the air.

In addition, the adhesive layer 433b should be uniformly formed so as not to generate bubbles on the surface. For example, the manufacturing process of the large area digital sensor panel 430 according to the third embodiment of the present invention is preferably performed in a vacuum chamber.

Hereinafter, a method of manufacturing a large area digital sensor panel according to a third embodiment of the present invention will be described with reference to FIG. 4C.

4C is a flowchart illustrating a manufacturing method of a large area digital sensor panel 430 according to a third embodiment of the present invention.

Referring to FIG. 4C, in the manufacturing method of the large-area digital sensor panel 430 according to the third embodiment of the present invention, the TFT panel 431 is first mounted and fixed on a flat surface, and the first dispensing apparatus ( The dam 433a is formed using the 440.

In this case, the first dispensing device 440 moves along the edge of the TFT panel 431 on the TFT panel 431 to apply the first curable material to form a dam 433a.

In this case, since the first hardenable material does not flow well due to its high viscosity, the first hardenable material may be adhered to an unintended place to compensate for a conventional defect that caused a problem.

The dam 433a is formed to assist in making the adhesive layer 433b bonding the TFT panel 431 and the scintillator panel 432 uniform, and after curing, the TFT panel 431 and the scintillator panel. By adhering the periphery of 432 to prevent the deterioration of the scintillator panel 432 by the moisture in the air.

That is, the dam 433a may be formed in a frame shape having a constant height to protect the inside from the outside at the edge portion of the TFT panel 431.

Subsequently, in the manufacturing method of the large-area digital sensor panel 430 according to the third embodiment of the present invention, the second curable material is prepared in the second dispensing apparatus 450. In addition, the second dispensing device 450 dispenses the second curable material into the dam 433a by filling the second curable material while moving up and down or left and right on the TFT panel 431. As a result, an adhesive layer 433b for bonding the TFT panel 431 and the scintillator panel 432 is formed.

In this case, it is preferable to use a higher viscosity than the second curable material, and the first curable material may be a thermosetting material or a UV curable material. Meanwhile, liquid silicon may be used as the second curable material, and the adhesive layer 433b having a uniform surface is formed by applying the liquid silicon to the TFT panel 431.

The dam 433a is molded and adhered to the edge of the scintillator panel 432 by mounting the scintillator panel 432 on the adhesive layer 433b. Therefore, the scintillator layer 432a of the scintillator panel 432 may be protected from water vapor in the atmosphere.

In addition, the process of adhering the scintillator panel 432 onto the TFT panel 431 on which the adhesive layer 433b is formed during the manufacturing of the large-area digital sensor panel 430 described above is as described in the second embodiment of the present invention. Likewise, it can be carried out by a vacuum compression method inside the vacuum chamber.

In addition, the TFT panel 531 is provided with a plurality of holes so that the other surface is adsorbed by the support table 540 capable of vacuum-adsorbing the panel.

At this time, when the TFT panel 531 is adsorbed to the support table 540, one surface with the photodiode is directed downward. In addition, among the surfaces of the TFT panel 531, the other surface adsorbed to the support table 50 is a surface without a photodiode.
