Display device and driving method thereof |
摘要 |
A display device includes: a control board on which a timing controller (TCON) and a power management integrated circuit (PMIC) are installed; a first source board on which a driving integrated circuit (IC) is installed; and a first connection cable that connects the control board and the first source board. The control board includes a first sensing line that connects the PMIC to the first connection cable and a third feedback line that connects the first connection cable to the TCON, the first connection cable includes a second sensing line that connects the first sensing line to the first source board and a second feedback line that connects the third feedback line to the first source board, and the first source board includes a third sensing line connected to the second sensing line and a first feedback line connected to the second feedback line. |

1. A display device, comprising:
a control board on which a timing controller (TCON) and a power management integrated circuit (PMIC) are installed; a first source board on which a driving integrated circuit (IC) is installed; and a first connection cable that connects the control board and the first source board, wherein the control board includes a first sensing line that connects the PMIC to the first connection cable and a third feedback line that connects the first connection cable to the TCON, the first connection cable includes a second sensing line that connects the first sensing line to the first source board and a second feedback line that connects the third feedback line to the first source board, and the first source board includes a third sensing line connected to the second sensing line, and a first feedback line connected to the second feedback line, wherein the PMIC outputs a sensing signal to the first sensing line, and the TCON determines a connection state of the control board and the first source board from a signal received from the third feedback line. |
