This application claims the benefit of, and priority to, Chinese Patent Application No. 201510875982.3, filed Dec. 2, 2015, titled “liquid crystal display panel and electronic device adopting liquid crystal display panel thereof”, the entire contents of which are incorporated by reference herein in its entirety.

However, since the pixel points of the liquid crystal display panel are greatly increased, it causes the increase of the power consumption and the frame flicker. In the thin film transistor liquid crystal display (TFT-LCD), the polarity reversal manner of the pixel point voltage adopts the row reversal when the resolution is low and adopts the column reversal when the resolution is high, so as to decrease the flicker level of the display frame and increase the display quality.

In the plurality of strip common electrodes 170, along the X axis direction, the strip common electrodes 170 in odd columns are connected to the first control line 110, and the strip common electrodes 170 in even columns are connected to the second control line 130. The first control line 110 is used for providing a first driving voltage for the strip common electrodes 170 in odd columns, so as to provide a first common voltage to at least one sub pixel column 150 covered by the strip common electrodes 170 in odd columns through the first driving voltage. The second control line 130 is used for providing a second driving voltage for the strip common electrodes 170 in even columns, so as to provides a second common voltage to at least one sub pixel column 150 covered by the strip common columns 170 in even columns through the second driving voltage.
In the embodiment, assuming that a resolution of the liquid crystal display panel 100 is 1920×1080, the liquid crystal display panel 100 includes 1080×3=3240 sub pixel columns 150. Correspondingly, the liquid crystal display panel 100 may includes 3240 strip common electrodes 170, and each of the strip common electrodes 170 covers one sub pixel column 150. Along the X axis direction, the strip common electrodes 170 in odd columns are connected to the first control line 110, so as to provide the first common voltage to the sub pixel columns 150 in odd columns in the X axis direction through the first driving voltage of the first control line 110.

When adopting the column reversal driving, along the X axis direction, a polarity of the data voltages of the data lines corresponding to the sub pixel columns 150 in odd columns and a polarity of the data voltages of the data lines corresponding to the sub pixel columns 150 in even columns are reverse. Therefore, for the data voltage with the different polarities, the first control line 110 and the second control line 130 respectively provide an alternating current voltage with reverse phase, thereby achieving the column reversal driving of the sub pixel sub columns 150 in odd columns and the sub pixel sub columns 150 in even columns.
