DISPLAY DEVICE AND METHOD OF DETECTING DETERIORATION OF THE SAME
First Claim
1. A display device comprising:
- a display panel;
a power supply unit configured to provide a power supply voltage to the display panel;
a first current measuring unit connected to a first path for providing the power supply voltage from the power supply unit to the display panel, the first current measuring unit configured to measure a first current flowing through the first path; and
an overcurrent preventing switch connected in parallel with the first current measuring unit, the overcurrent preventing switch configured to selectively form a detour path for the first path according to an amount of the first current such that at least a portion of the first current flows through the detour path.

Abstract
A display device includes a display panel, a power supply unit, a first current measuring unit, and an overcurrent preventing switch. The power supply unit provides a power supply voltage to the display panel. The first current measuring unit is connected to a first path for providing the power supply voltage from the power supply unit to the display panel and measures a first current flowing through the first path. The overcurrent preventing switch is connected in parallel with the first current measuring unit and selectively forms a detour path for the first path according to an amount of the first current such that at least a portion of the first current flows through the detour path.
