Fig. 4 A is transmitance simulated effect figure of the existing liquid crystal display panel when wide viewing angle is shown.Fig. 4 B is the present invention
Transmitance simulated effect figure of the liquid crystal display panel of first embodiment when wide viewing angle is shown.As shown in fig. 4 a and fig. 4b, existing
The transmitance that the liquid crystal display panel wide viewing angle of technology is shown is 3.82%, the wide view of the liquid crystal display panel 100 of the present embodiment
Transmitance when angle is shown reaches 3.34%, i.e., transmitance phase when 100 wide viewing angle of liquid crystal display panel of the present embodiment is shown
13% is had dropped for the 3.82% of the prior art, this difference can be designed by pixel so that display area 101 and viewing angle control
Region 102 reaches optimum balance to reduce.For example, can be each by each pixel of display area 101 and viewing angle control region 102
The a quarter for accounting for entire pixel unit P, since viewing angle control region 102 is controlled without thin film transistor (TFT), in design
Can be different with other three sub-pixels, can be by the range shorter of the black matrix in viewing angle control region 102, the area that will be had more
Other three sub-pixels are given to supply the difference with the liquid crystal display panel of prior art transmitance under wide viewing angle mode.
As shown in figure 3, display area 101 still generates fringe field, the liquid in display area 101 under narrow viewing angle mode
Brilliant molecule is acted on by fringe field, and the viewing angle control electrode 25 in viewing angle control region 102 applies viewing angle control voltage, such as hands over
Galvanic electricity presses 2~4V, and it is 0V that the public electrode 15 on first substrate 10, which applies common voltage, in viewing angle control electrode 25 and common electrical
Vertical electric field (arrow direction in such as figure) is generated between pole 15, the liquid crystal molecule in viewing angle control region 102 is made by vertical electric field
With and deflect to vertical state, therefore seen at positive visual angle, liquid crystal molecule is in a vertical state, opaque, observes liquid crystal in side
When showing 100 screen of panel, liquid crystal molecule is in heeling condition, generates lateral light leakage, and then realizes that narrow viewing angle is shown.
In the present embodiment, by the way that the pixel electrode on first substrate 10 with 102 corresponding position of viewing angle control region is taken away
And the white space 14 is formed, to increase narrow viewing angle bevel edge light leakage area, strengthen narrow viewing angle effect.It should be noted that regarding
In angle control area 102, there is no an electric field presence between first substrate 10 and the second substrate 20 when wide viewing angle is shown, therefore liquid crystal molecule
Original state is kept, liquid crystal display panel 100 is in black display.When narrow viewing angle is shown between first substrate 10 and the second substrate 20
There are vertical electric field, there is no electric field in horizontal direction, liquid crystal molecule is only acted on by vertical electric field, and positive visual angle light leakage reduces, and can be had
Effect improves the peep-proof angle of narrow viewing angle.
Fig. 5 A is transmitance simulated effect figure of the existing liquid crystal display panel when narrow viewing angle is shown.Fig. 5 B is the present invention
Transmitance simulated effect figure of the liquid crystal display panel of first embodiment when narrow viewing angle is shown.It please join Fig. 5 A and Fig. 5 B, it is existing
Liquid crystal display panel narrow viewing angle mode transmitance be 2.3%, the liquid crystal display panel 100 of the present embodiment is in narrow viewing angle mould
The transmitance of formula reaches 3.34%, this compared with the existing technology 2.3% improve 45%.By Fig. 5 A it is found that the prior art
The problem of dark-state light leakage is big more than the dark-state light leakage of the present embodiment, and there is also brightness disproportionations, causes whole contrast not
It is high.The liquid crystal display panel 100 of the present embodiment only has vertical electric field, level side in narrow viewing angle mode downwards angle of visibility control area 102
There is no electric field upwards, the arrangement of liquid crystal molecule horizontal direction is unaffected, and light leakage is very small, effectively improves the peep-proof of narrow viewing angle
Contrast also greatly promotes while angle.
In the present embodiment, when leniently field-of-view mode is switched to narrow viewing angle mode, picture, example are shown with lower operation voltage
If the operation voltage of wide viewing angle is 0~3.6V, voltage is operated when switching to narrow viewing angle mode can be reduced to 0~2.8V (Tr=
2.9%, CR > 300) or 0~2.5V (Tr=2.49%, CR > 250), transmitance be still greater than existing operation voltage 0~
3.6V (Tr=2.3%, CR~150), and contrast is higher than the prior art.
As shown in Fig. 4 B and Fig. 5 B, in the present embodiment, under wide viewing angle mode, operation voltage is 3.6V, and transmitance is
3.34%, under narrow viewing angle mode, operation voltage is 3.6V, and transmitance 3.34% improves narrow viewing angle compared with the existing technology
Transmitance when display, so that the brightness at width visual angle is consistent with contrast.
The liquid crystal display panel 100 of the present embodiment can also be driven with 60Hz, flicker free and the problem of mura, reduce liquid crystal
The production cost of display panel 100 also avoids the problem of narrow viewing angle shows wide-angle gray-scale inversion.
