DRIVE CONTROL DEVICE, DISPLAY DEVICE EQUIPPED WITH THE SAME, AND DRIVE CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide a drive control device which prevents an increase in power consumption and breakage of a circuit element caused by abnormality in a gate start pulse signal in a display device including a gate driver consisting of a plurality of cascade connected ICs.SOLUTION: In a drive control device, a gate start pulse signal output from each IC (GDR1-GDR4) is input into a subsequent IC and also applied to a timing controller IC 100. The timing controller IC 100 compares a value of the gate start pulse signal output from each IC with an expectation value of the gate start pulse signal so as to determine presence/absence of abnormality. When there is the abnormality in the gate start pulse signal, the timing controller IC 100 executes a processing to stop the gate output from the IC to which the abnormal gate pulse signal is input.
