Abstract
A display apparatus and an assembly of a driving circuit for the display apparatus having a display device, a film carrier with a lead to transfer a signal for driving the display device, and a bus board to supply a signal to the lead. A dummy lead is provided along the outside of each of an input side outer lead and an output side outer lead of the film carrier. A predetermined voltage is applied to the dummy leads. The predetermined voltage value is set to a value so as not to stationarily cause a DC bias for the voltage of the outer lead on the outside.
Claims18
An assembly of a driving circuit for a display apparatus comprising a display device, a film carrier having a lead to transfer a signal for driving said display device, and a bus board for supplying a signal to said lead, wherein
- a dummy lead is provided along the outside of each of an input side outer lead and an output side outer lead of said film carrier, and a predetermined voltage is applied to said dummy leads.
A display apparatus comprising:
- a display device having a group of electrodes for supplying signals to pixels;
- a bus for transferring the signals which are supplied to said group of electrodes or signals to drive said electrodes;
- and
- a film carrier having a group of leads for electrically connecting said group of electrodes of said display device and connecting terminals of a bus board;
- wherein said film carrier has dummy leads on both sides of said group of leads, and a DC component of a voltage difference which is caused between said dummy lead and a lead adjacent to said dummy lead is almost equal to zero in a predetermined period of time.
