Region 2 and pixel region 3 apply the first driving voltage to pixel region 1, apply the second driving voltage to pixel region 2, right
Pixel region 3 applies third driving voltage.
It can be seen from the above, by taking a pixel unit as an example, the B sub-pixels in 3 adjacent pixels are located at three respectively
In different pixel regions, for example, the B sub-pixels in pixel a are located at the first pixel region, apply the first driving electricity thereon
Pressure, under the driving of the first driving voltage so that the corresponding liquid crystal molecule rotation of B sub-pixels in pixel a.In pixel b
B sub-pixels be located at the second pixel region, apply the second driving voltage thereon, under the driving of the second driving voltage so that as
The corresponding liquid crystal molecule rotation of B sub-pixels in vegetarian refreshments b.B sub-pixels in pixel c are located at third pixel region, thereon
Apply third driving voltage, under the driving of third driving voltage so that the corresponding liquid crystal molecule of B sub-pixels in pixel c
