DISPLAY DEVICE AND METHOD OF MEASURING CONTACT RESISTANCE THEREOF |
| 摘要 |
Provided are a display device and a method for measuring contact resistance thereof. A plurality of dummy bumps disposed on a driving circuit or a flexible circuit board are connected to shorting pads disposed on the display panel, and bonding resistance is measured by comparing an input voltage of a comparator input through bonding resistance between dummy bumps and shorting pads with a variable reference voltage. |
