各位大侠好！
请教个问题，大家有人知道吗？谢谢帮忙理解一下其中的原理。
问题背景：汽车中控显示屏是10英寸，1080P高清屏，在配和车机主机模块（安卓系统主机），显示屏有时会闪烁。
主机模块和屏幕是通过LVDS线传输的。其中主机模块上有TI 的串行器DS90Ux947，屏幕内部电路板上有相应的解串器芯片。
研发团队分析：
1. System level troubleshooting on DS90Ux947(TI Serializer) identified a potential problem. Display could potentially show anomalous data pattern, jittered–data, blank, or rolling display with 1080p configuration.
2. A detailed investigation of the unit in question revealed the incoming data bit positions were shifted causing the sync signals to be Mis-sampled, the issue was traced to a design marginality within TI Serializer with the OLDI clock generation block, specific to dual OLDI mode(Dual OLDI is used for 1080p displays)
解决方案：
Solution : In the startup both the Kernel and Panel Services implemented a detection mechanism to check the resolution of the Display.
If the display is not 1920x1080p resolution as expected, then on runtime a OLDI reset command is issued to Serializer to regain the expected resolution 1080p.
这个英文解释是个什么原理，有高手指点一下吗？非常感谢。
