Abstract:
1. A display panel driver, comprising: an interface for receiving low voltage differential signals and retrieving video signals, synchronous signals, clock signals and control signals from the low voltage differential signals; a timing controller for generating a display control signal based on the synchronous signals, clock signals and control signals retrieved by the interface; and a signal line driving portion for generating and outputting driving signals for driving signal lines of a display panel based on the video signals retrieved by the interface and the display control signal generated by the timing controller, wherein the relationship is satisfied where a transmission path length between the interface and the timing controller is L 1 , a propagating speed of electromagnetic waves in a vacuum is V, a frequency of a signal transmitted between the interface and the timing controller is F 1 , and a comparative dielectric constant of a transmission path medium between the interface and the timing controller is ∈ 1 , and the relationship is satisfied where a transmission path length between the timing controller and the signal driving portion is L 2 , a propagating speed of electromagnetic waves in a vacuum is V, a frequency of a signal transmitted between the timing controller and the signal line driving portion is F 2 , and a comparative dielectric constant of a transmission path medium between the timing controller and the signal line driving portion is ∈ 2 .
