摘要： A driver chip, a driver board and a test method thereof, and a display device. The driver chip includes a first internal interface, a second internal interface and a test circuit for performing a short-circuit detection on the internal interfaces, including an input unit and a test unit. The input unit is connected to a test signal input terminal and the first internal interface for transmitting a test signal inputted to the test unit and the first internal interface when in an ON state. The test unit is connected with the second internal interface and a test signal output terminal used for preventing a signal outputted by the input unit from being outputted from the test unit when in an OFF state. The test method detects whether a short-circuit has occurred to interfaces on the driver chip.

摘要： A signal correcting method and a signal correcting device. The signal correcting method includes sampling a signal to be corrected at different sampling times, and comparing a signal value at each of the sampling times in one signal period with a preset signal value corresponding to the sampling time. When the signal value at the sampling time is equal to the corresponding preset signal value, the signal value at the sampling time is kept unchanged. When the signal value at the sampling time is not equal to the corresponding preset signal value, the signal value at the sampling time is corrected to be the preset signal value corresponding to the sampling time.
