Organic light emitting diode display device and method of driving the same
First Claim
1. An organic light emitting diode display device, comprising:
- a first substrate;
a second substrate;
a sealing material sealing a space between the first and second substrates and applied along an edge of the second substrate;
an interconnection disposed inside the sealing material; and
a test unit connected to both ends of the interconnection and configured to measure a preset voltage applied to the interconnection, to compare the measured voltage with a reference voltage, and to determine whether or not a crack occurred in the sealing material.

Abstract
An organic light emitting diode display device and a method for driving the same.
The organic light emitting diode display device includes a first substrate, a second substrate, a sealing material sealing a space between the first and second substrates and applied along an edge of the second substrate, an interconnection disposed inside the sealing material, and a test unit connected to both ends of the interconnection and configured to measure a preset voltage applied to the interconnection and compare the measured voltage with a reference voltage to determine whether a crack occurred in the sealing material or not. Further, the same effect can be obtained by measuring and comparing currents instead of the voltages.
