Into EMI increase the problem of.
Technical scheme is described in detail with specifically embodiment below.These specific implementations below
Example can be combined with each other, and may be repeated no more for same or analogous concept or process in some embodiments.
Fig. 1 shows for the flow provided by the present invention for the method for adjustment embodiment one of electromagnetic interference peak value in display device
It is intended to.The executive agent of the present embodiment is the adjusting apparatus with electromagnetic interference in adjustment display device.What the present embodiment was related to
It is target power of the adjusting apparatus based on the impedance between SOURCE plates and target COF plates and target COF plate data to be displayed, really
Determine the detailed process that SOURCE plates transmit the transmission time of data to be displayed to target COF plates.As shown in figure 1, the present embodiment can
With including：
S101, the mesh based on the impedance between SOURCE plates and target COF plates and the target COF plate data to be displayed
Power is marked, determines that the SOURCE plates transmit the transmission time of the data to be displayed to the target COF plates.
Wherein, the target COF plates data to be displayed is the partial data in a line data to be displayed.
For liquid crystal display, some COF plates are near apart from SOURCE plates, some COF plates apart from SOURCE plates farther out.So
So that SOURCE plates and the length of the connecting line of different COF plates are incomplete same, cause between different COF plates and SOURCE plates
Impedance differ.For example, its longer impedance of connecting line is bigger.
At present, during the transmission of data, the driving that each COF plates are given in front end is consistent, simply according to both
Fixed sequential is passed data on COF plates, because COF plates have distance, reaches that the time of each COF plate does not unite in fact
One, that is to say, that the time that data reach each COF plates has differences.
