Abstract
This invention discloses a splicing display device, comprising: a plurality of display modules interconnected via a first interface circuit and a second interface circuit, each display module including a timing controller configured to determine whether a corresponding display module is faulty and output a defect occurrence and location signal in response to determining that the corresponding display module is a faulty module; and a setting board configured to: receive the defect occurrence and location signal output from the faulty module via the first interface circuit during a first time period, generate a defect identification completion signal in response to receiving the defect occurrence and location signal, transmit the defect identification completion signal via the second interface circuit during a second time period after the first time period, and receive a defect history signal of the faulty module from the faulty module via the first interface circuit during a third time period after the second time period.
