The frame period of each pixel structure is divided into a first frame period and a second frame period, and a first voltage is applied to the pixel structure during the first frame period and a second voltage is applied to the pixel structure during the second frame period, wherein the first voltage is different from the second voltage. The gray scale range of the display panel is sequentially divided into a first gray scale area, a second gray scale area, a third gray scale area and a fourth gray scale area. In the first gray scale region and the third gray scale region, a difference value between the first voltage and the second voltage increases with an increase in gray scale value.

Apply that example is similar, therefore details are not described herein for similar content.The discrepancy of the embodiment of the present embodiment and Fig. 4 is, in this implementation
In example, L1 grayscale is 84 grayscale, and L2 grayscale is 144 grayscale, and L3 grayscale is 200 grayscale.That is, in the present embodiment,
First gray-scale areas R1 is 0 grayscale between 84 grayscale, and the second gray-scale areas R2 is 84 grayscale between 144 grayscale, the 3rd ash
Rank region R3 is 144 grayscale between 200 grayscale, and the 4th gray-scale areas R4 is 200 grayscale between 256 grayscale.It is worth noting
, above-mentioned grayscale L1~L3 is using single-point as illustration, however, the present invention is not limited thereto.In other embodiments, grayscale L1~L3
Can also be a scope respectively.For example, L1 grayscale can be 80 grayscale between 90 grayscale, L2 grayscale can be 128
Grayscale is between 150 grayscale, and L3 grayscale can be 177 grayscale between 200 grayscale.That is, the first gray-scale areas R1
It is 0 grayscale between 80 to 90 grayscale, the second gray-scale areas R2 is 80 to 90 grayscale between 128 to 150 grayscale, the 3rd grayscale
Region R3 for 128 to 150 grayscale between 177 to 200 grayscale, the 4th gray-scale areas R4 is 177 to 200 grayscale to 256 grayscale
Between.
Similar to the embodiment of Fig. 4, the present embodiment cuts into the first picture cycle by by the picture cycle of dot structure
And second picture cycle and provide different specific voltages respectively during this two picture cycles, and when dot structure P's
When grayscale is L2 grayscale, difference between first voltage V1 and second voltage V2 can between 1.4 volts to 3.5 volts,
Also can reach reduces hue error value and raising colourity visual angle and other effects.
In conclusion the present invention cuts into the first picture cycle and the second picture by by the picture cycle of dot structure
Cycle simultaneously provides different specific voltages respectively during this two picture cycles, can on the premise of penetrance is not lost,
Solve the situation of side view angle partially white (color washout).Can be with since penetrance is not sacrificed, therefore the effect of display panel
It is elevated, and the visual angle of display panel and colourity can be also effectively increased.
Although the present invention is disclosed as above with embodiment, it is not limited to the present invention, any technical field
Technical staff, without departing from the spirit and scope of the present invention, when can make a little change with modification, therefore the present invention protection
Scope is when subject to appended claims protection domain institute defender.
