EL display panel with gate driver circuits mounted on flexible board including terminal connection lines connecting connection parts and control terminals

摘要

The number of control lines to be formed on a COF in serial connection is reduced. An EL display includes a flexible board including: a plurality of connection terminals arranged at one side for connection with panel lines formed on a panel board; terminal connection lines for connecting points inside the flexible board with the connection terminals; serial connection lines for connecting between two or more of the connection terminals. On the flexible board: driver output terminals of each of gate driver ICs are connected to terminal connection lines; driver input terminals of the gate driver IC are connected to either terminal connection lines or the serial connection lines; and control terminals for performing logic setting of the gate driver IC are each arranged between connection terminals and driver input terminals to which the serial connection lines are connected.
