发明名称 Current feedback-type amoled driving circuit
摘要 A current feedback-type AMOLED driving circuit. The current feedback-type AMOLED driving circuit includes a plurality of pixel circuits each having a data terminal for receiving a pixel current command, and a sense terminal for transmitting pixel current to a driver Integrated Circuit (IC), and a plurality of data lines provided such that a single data line is provided for a single column formed by a plurality of pixel circuits, thus data terminals of the pixel circuits, forming the column, are connected to the data line. In the AMOLED driving circuit, two columns are paired, sense terminals of pixel circuits, forming a first column of the two columns, are connected to a data line for a second column, and sense terminals of pixel circuits, forming the second column, are connected to the data line for the first column. The AMOLED driving circuit is operated such that, when the first column is driven, the data line for the second column is used as a current feedback line for the first column, and when the second column is driven, the data line for the first column is used as a current feedback line for the second column. Accordingly, the number of pads of the driver IC is limited to one per column, and price competitiveness of the driver IC is improved.
