Two source driving chip IC2 are responsible for the data-driven of the pixel cell of 1921-3840 row.But it is limited to the limit of manufacturing process
System, the parameter of the source driving chip for the same model produced can not possibly be completely the same, then, when the source of multiple same models
When pole driving chip inputs same signal, there is some difference for the data meeting of output.So, the display of split screen control is being demarcated
Cut-off rule phenomenon occurs at line, and then influences display effect.
For example, when first source driving chip IC1 and second source driving chip IC2 input same signal in Fig. 1,
The data voltage that the pixel cell that the data voltage that the pixel cell of 1-1920 row obtains and 1921-3840 are arranged obtains is different, this
The GTG that the pixel cell of sample 1-1920 row and the pixel cell of 1921-3840 row are shown will be different, and then in the 1920th row
And the 1921st row between there is cut-off rule phenomenon, so as to influence display effect.
