Problems solved by technology

[0006] However, although the EMI characteristics in the low frequency band can be improved using the LVDS or RSDS method, the EMI characteristics in the high frequency band cannot be improved
If a high frequency region of 800MHz to 6GHz is used in the case of wireless WAN and wireless LAN, EMI characteristics cannot be improved in this frequency region even if LVDS or RSDS is used

Abstract

The invention relates to a circuit board and a display device including the same. One or more embodiments of the present disclosure relate to the circuit board having a substrate and a plurality of differential signal lines formed on the substrate and transmitting differential signals. The differential signal lines include a first signal line and a second signal line. The first signal line and the second signal line extend along at least two paths that are parallel to each other. The paths of the first signal line and the second signal line switch at path change portions, and the path change portions of neighboring differential signal lines are positioned at different distances away from an edge of the circuit board along the length direction of the differential signal line.

Description

technical field [0001] The present invention relates to a circuit board and a display device including the circuit board, in particular, to a circuit board including differential signal lines and a display device including the circuit board. Background technique [0002] Flat panel displays such as liquid crystal displays (LCDs), plasma display devices (PDPs), field emission displays (FEDs), vacuum fluorescent displays (VFDs), and organic light emitting displays (OLEDs) are widely used. [0003] These display devices generally include a display panel and a signal controller for supplying signals to the display panel. The display panel receives signals through a flexible printed circuit film connected to a signal controller. The signal controller includes a TCON (Timing Controller) and an IC chip (Integrated Circuit Chip), and they are connected to wiring arranged at the same layer or at different layers. The flexible printed circuit film includes a film, a plurality of wir...
