CURRENT FEEDBACK TYPE AMOLED DRIVING CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide a compact current feedback type AMOLED driving circuit whose cost is reducible.

SOLUTION: The current feedback type AMOLED driving circuit includes a driving IC (100) and first and second columns (100a, 100b). Each column includes a plurality of pixel circuits and one data line and each of the pixel circuits has a data terminal connected to a corresponding data line and a sense terminal for transmitting a pixel current to the driving IC. A sense terminal of each pixel circuit of the first column is connected to the data line of the second column and a sense terminal of each pixel circuit of the second column is connected to the data line of the first column. The first and second columns are program in a time-division manner; when the first column is driven, the data line of the second column is used as a feedback line of the first column and when the second column is driven, the data line of the first column is used as a current feedback line of the second column.
