PIXEL DRIVE DEVICE, LUMINESCENCE DEVICE, DISPLAY DEVICE, AND METHOD OF CONNECTING CONNECTION UNIT IN PIXEL DRIVE DEVICE

摘要

PROBLEM TO BE SOLVED: To suppress a difference between input and output terminal potentials measured when the connection of a TFT panel and a current source unit is switched.

SOLUTION: Having the terminal number p of the current source unit 161 as one block, a switching unit 163 connects the input/output terminals D((b-1)×p+k) of the TFT panel 11 to the connection terminals P161(k) of a current source unit 161 if the block number b is odd. The switching unit 163 connects each input/output terminal D((b-l)×p+k) of the TFT panel 11 to the connection terminal P161(p-k+l) of the current source unit 161 if the block number b is even. A measuring unit 162 measures the potentials Vs(1) to Vs(m) of the input output terminals D(1) to D(m) for each block.
