Abstract
A method of repairing organic light-emitting element pixels for repairing an organic light-emitting element having a substantial short circuit portion or portions. The method includes an electrical testing step and an insulator-forming step. The organic light-emitting element includes an anode substrate, an organic functional layer and a cathode. In this case, a current or voltage is applied to the anode substrate and the cathode of the organic light-emitting element respectively in the electrical testing step, so that the short circuit portion or portions of the organic light-emitting element are transformed to an open circuit portion or portions. In the insulator-forming step, an insulator is formed at the open circuit portion or portions of the organic light-emitting element. The invention also discloses a method of repairing organic light-emitting element pixels, which further includes an electrical detection step. A short-circuit level of the organic light-emitting element is detected in the electrical detection step. When the ratio of the amount of the short circuit portions to the amount of the open circuit portions is less than a predetermined value, the insulator is formed on the open circuit portions in the subsequent insulator-forming step.
