Patent ID: 7791701

Claim:
A circuit film, comprising: a film substrate; a first circuit formed on the film substrate for outputting a driving signal to a display device, the display device including at least a display panel which has at least a first signal line and a second signal line, a second-circuit film which has a second circuit for outputting a driving signal to the second signal line, a wire board which has a second-circuit line for inputting a control signal to the second circuit, a control board for controlling at least the first and second circuits; and a plurality of input lines formed on the film substrate, wherein one end of the second-circuit film is connected to the wire board, and the other end of the second-circuit film is connected to the display panel, the film substrate has a first region arranged to be connected to the control board, a second region arranged to be connected to the wire board, and a third region arranged to be connected to the display panel, the plurality of input lines include at least a first input line for inputting a control signal to the first circuit and a second input line for inputting a control signal to the second-circuit line, and the film substrate is directly connected through an anisotropic conductive film to each of the display panel, the wire board, and the control board such that a control signal is input from the control board to the first circuit through the first input line, and a control signal is input from the control board to the second circuit through the second input line and the second-circuit line.
