Plane switches (In Panel Switching, IPS) formula.There are higher lifes compared to IPS liquid crystal technology for VA type liquid crystal technology
The advantage of efficiency and low manufacturing cost is produced, but compared to IPS liquid crystal technology, then there is obvious optical property defect, such as
When wide-angle image is presented, VA type liquid crystal display panel can have colour cast.

Dynamic voltage Vgd=V2 then can preferably original frame picture element signal Gd3 and Gd4 signal average signal, that is, G2=(Gd3+
Gd4 the corresponding driving voltage V2 of)/2, G2, two adjacent high-low voltage sub-pixel driving voltages share and column
The driving method of inversion greatly reduced driving signal and frequently switch, and directly drives frequency and is reduced to 1/2, can be with
The work for reducing driving IC, the power consumption for reducing driving IC and the temperature for driving IC promote risk.
Please continue to refer to attached drawing 5, tri- sub-pixels of R, G, B constitute a unit pixels, adjacent any unit pixel be with
The interspersed arrangement of high-low voltage driving.
G column sub-pixel has two common electrode potential circuits, two common-battery pole tensions of respectively Vcom1 and Vcom2, G column
The high voltage sub-pixel and low-voltage sub-pixel of pixel respectively correspond the first predeterminated voltage Vcom1 and the second predeterminated voltage Vcom2,
Driving signal carries out polarity switching by the way of column inversion, and common-battery pole tension is carried out also with the polar switching of frame driving signal

Ginseng R, G, B of B column can arrange adjacent three column sub-pixels driving arrangement mode explanation in attached drawing 5, with a line sub-pixel
As R, B column sub-pixel high-low voltage of G column sub-pixel two sides drive with G column sub-pixel high-low voltage.Therefore, in order to realize height
Voltage normally interts driving, and one group of common-battery pole tension that arranging adjacent R, B column with G respectively has corresponds to Vcom2 and Vcom1, arranges with G
The common-battery pole tension Vcom1 of same position is identical as Vcom2.It is adjacent with high voltage sub-pixel VGd_1 by taking B column sub-pixel as an example
Low-voltage sub-pixel VBd_1 correspond to the equivalent voltage VBd_1=of common-battery pole tension Vcom1 | VB1-Vcom2 |, with low-voltage
Pixel VGd_2 adjacent high voltage sub-pixel VBd_2 corresponds to the equivalent voltage VBd_2=of common-battery pole tension Vcom2 | VB1-
