Apparatus and method for arranging a spacer
View Patent ↗An apparatus for arranging a spacer includes a substrate, a roller, and an adhesion unit. The substrate includes a recessed portion. A spacer, which maintains a cell gap of a display panel and has an adhesive member formed thereon, is received in the recessed portion. The roller corresponds to the spacer. The roller makes contact with an exposed portion of the adhesive member. The adhesion unit provides for an adhesive strength between the exposed portion of the adhesive member and the roller that exceeds an adhesive strength between the received portion of the adhesive member and the recessed portion of the substrate so that the spacer may be printed on the roller. Therefore, a cell gap uniformity of a display device may be improved.
1. A method for arranging a spacer, comprising:
aligning a spacer having an adhesive member formed thereon on a substrate that comprises a recessed portion;
providing an adhesive strength between an exposed portion of the adhesive member and a roller that is stronger than an adhesive strength between a received portion of the adhesive member and the recessed portion of the substrate;
printing the spacer and the adhesive member on the roller; and
attaching the received portion of the adhesive member to a display substrate to print the spacer on the display substrate.
2. The method of claim 1 , wherein providing the adhesive strength between the exposed portion of the adhesive member and the roller that is stronger than the adhesive strength between the received portion of the adhesive member and the recessed portion of the substrate comprises spraying a coolant on the roller.
3. The method of claim 2 , further comprising heating the recessed portion of the substrate.
4. The method of claim 1 , wherein providing the adhesive strength between the exposed portion of the adhesive member and the roller that is stronger than the adhesive strength between the received portion of the adhesive member and the recessed portion of the substrate comprises spraying a coolant on the exposed portion.
5. The method of claim 4 , further comprising heating the recessed portion of the substrate.
6. The method of claim 1 , further comprising removing a remaining spacer that remains in the recessed portion from the recessed portion after attaching the spacer and the adhesive member on the roller.
7. The method of claim 6 , wherein removing the remaining spacer comprises spraying a fluid in the recessed portion.
8. The method of claim 1 , wherein providing the adhesive strength between the exposed portion of the adhesive member and the roller that is stronger than the adhesive strength between the received portion of the adhesive member and the recessed portion of the substrate comprises irradiating a sonic wave on the recessed portion.
9. The method of claim 1 , wherein the printing of the spacer on the display substrate further comprises heating the roller so that a temperature of the roller is greater than a temperature of the display substrate.
10. The method of claim 9 , wherein the roller is heated by a fluid that has a greater temperature than the temperature of the display substrate.
11. The method of claim 1 , wherein the printing of the spacer on the display substrate further comprises irradiating a sonic wave on the roller.
