Hi All,

I just got back information regarding LCD red dot display problem.  
The reason is how color/RGB is configured. See the last page of [1].  
The currently used LCD is RGB Delta Configurational. The problem  
could be resolved by using dot scanning instead of line scanning.  
Unfortunately the LCD controller in Ingenic JZ4720 CPU only supports  
line scan. Which means for now the red dot display problem will  
remain as it is.
