Abstract
A tiling display apparatus includes a plurality of display modules connected to one another through a first interface circuit and a second interface circuit and a set board receiving a defect occurrence and position signal, generated in a broken-down module of the plurality of display modules, from the broken module through the first interface circuit in a first period, generating a defect recognition completion signal in a second period succeeding the first period, and transferring the defect recognition completion signal to the broken-down module through the second interface circuit in the second period.
Claims11
A tiling display apparatus comprising:
- a plurality of display modules connected to one another through a first interface circuit and a second interface circuit, the plurality of display modules including a broken-down module having a timing controller configured to determine that the broken-down module is broken and output a defect occurrence and position signal responsive to the determination;
- and
- a set board receiving the defect occurrence and position signal output from the broken-down module through the first interface circuit in a first period, generating a defect recognition completion signal in a second period succeeding the first period that acknowledges a receipt of the defect occurrence and position signal responsive to receiving the defect occurrence and position signal, and transferring the defect recognition completion signal to the broken-down module through the second interface circuit in the second period,
- wherein each of the defect occurrence and position signal and the defect recognition completion signal is a pulse signal which swings between a high logic voltage and a low logic voltage, and
- wherein the set board further receives a defect history signal of the broken-down module from the broken-down module through the first interface circuit in a third period succeeding the second period.
A tiling display apparatus comprising:
- a set board;
- and
- a plurality of display modules connected to one another through a first interface circuit and a second interface circuit,
- wherein at least one of the plurality of display modules comprises:
- a timing controller configured to:
- determine that the display module is broken, generate a defect occurrence and position signal responsive to determining that the display module is broken, and output the defect occurrence and position signal to the set board through the first interface circuit in a first period, and receive, from the set board, a defect recognition completion signal that is generated by the set board and acknowledges a receipt of the defect occurrence and position signal by the set board responsive to receiving the defect occurrence and position signal through the second interface circuit in a second period succeeding the first period,
- wherein each of the defect occurrence and position signal and the defect recognition completion signal is a pulse signal which swings between a high logic voltage and a low logic voltage, and
- wherein the timing controller is further configured to generate a defect history signal of the display module and transfer the defect history signal to the set board through the first interface circuit in a third period succeeding the second period.
