The display is driven with parallel signals. Those signals must feed the circuitry all at the same time to avoid flickering or any other kind of artifacts. So it's important that the tracks match in length each other in order to have the same traveling time. The clock signal line only have to be a little bit longer to guarantee that all the other signals are stable at the right value when the clock triggers the frame. Leadtek developed the PCBA for converting signals from EDP/LVDS/RGB/MIPI to HDMI or HDMI+VGA, we also support displays with SSD1963. To know more information, welcome to send us inquiries.
