IMAGE DISPLAY DEVICE AND DRIVING METHOD OF THE SAME |
摘要 |
An image display device including a light-emitting element configured to emit light corresponding to a current flowing therethrough; a driving element that is connected to the light-emitting element and configured to control light emission of the light-emitting element; and a control unit configured to apply a reverse bias voltage to a first n-type driving element whose the threshold voltage determined at a specific time is equal to or higher than a positive predetermined voltage level for shifting the threshold voltage of the first n-type driving element in a negative direction, and not apply the reverse bias voltage to a second n-type driving element whose the threshold voltage determined at the specific time is lower than the positive predetermined voltage level for shifting the threshold voltage of the second n-type driving element in a positive direction when the light-emitting element does not emit light. |

1. An image display device comprising:
a light-emitting element configured to emit light corresponding to a current flowing therethrough; a driving element that is connected to the light-emitting element and configured to control light emission of the light-emitting element; and a control unit configured to:
apply a reverse bias voltage to a first n-type driving element whose the threshold voltage determined at a specific time is equal to or higher than a positive predetermined voltage level for shifting the threshold voltage of the first n-type driving element in a negative direction, andnot apply the reverse bias voltage to a second n-type driving element whose the threshold voltage determined at the specific time is lower than the positive predetermined voltage level for shifting the threshold voltage of the second n-type driving element in a positive direction when the light-emitting element does not emit light. |
