Research staff has found that the transmitance of display panel is related to the bearing of trend in strip shaped electric poles portion.Prior art provides
Display panel in, the bearing of trend in strip shaped electric poles portion and the angle of line direction are α, and α is 6 ° to 10 °；Or strip shaped electric poles portion
Bearing of trend and the angle of column direction be β, β is 6 ° to 10 °；α and β value is larger.The reason for so setting is, when finger is pressed
During the display panel of hydraulic fluid crystalline substance, liquid crystal is disturbed, it may appear that water ripple phenomenon, when finger leaves display panel, and water ripples
That recovers is slow, or is difficult to recover.By the larger of α and β value setting, water ripple phenomenon can be effectively weakened,
But the display panel transmitance that also result in prior art offer is relatively low, reduces display quality.
In the embodiment of the present invention, it is α, 1 °≤α ＜ to set the bearing of trend in strip shaped electric poles portion 60 and the angle of line direction
3°；Or it is β, 3 ° of 1 °≤β ＜, relative to existing skill to set the bearing of trend in strip shaped electric poles portion 60 and the angle of column direction
Art, α and β value are smaller, can effectively lift the contrast of display panel, lift display quality.Also, the embodiment of the present invention
The display panel of offer, vehicle-mounted head-up display device is mainly used in, user does not need touch display panel, and display panel is not
Water ripple phenomenon caused by pressing occurs.Therefore α and β value can be set smaller.
Below, Fig. 9 is refer to, is illustrated in Fig. 9 in the range of azimuth γ=90 ° to azimuth γ=270 °, is shown
Show the different bearing of trends in strip shaped electric poles portion and the gain of brightness decay in panel, with the technique effect of the explanation present invention.
On the basis of the display device shown in Fig. 1, the bearing of trend in strip shaped electric poles portion and the folder of line direction are set respectively
Angle α=1 °, α=3 °, α=4 °, α=10 ° are to illustrate the technique effect of the embodiment of the present invention.
In Fig. 9, abscissa represents visual angle β, wherein, β is that visual angle is close to the side of azimuth γ=90 ° on the occasion of expression；
β represents that visual angle is close to the side of azimuth γ=270 ° for negative value.The percentage of ordinate represents the extension in strip shaped electric poles portion
Direction from the angle α of line direction in different angles, the brightness decay gain of display panel.The display provided with prior art
In panel, the bearing of trend in strip shaped electric poles portion and the angle of line direction are α, and α=6 ° are used as a reference value, during α=6 °, display panel
Brightness decay gain in the range of azimuth γ=90 ° to azimuth γ=270 ° is 0%.Due to the black state of display panel
Brightness is not influenceed by the bearing of trend in strip shaped electric poles portion, and brightness decay gain is to increase on the occasion of expression brightness, then display panel
Contrast lifting；Brightness decay gain is that negative value represents brightness increase, then the contrast of display panel reduces.
Observation Fig. 9 can see, when strip shaped electric poles portion bearing of trend and line direction angle α=1 ° when, display panel
Luminance raising highest, thus the contrast lifting of display panel is maximum.When the bearing of trend and line direction in strip shaped electric poles portions
During angle α=10 °, the luminance-reduction of display panel, contrast is relatively low.When α=4 °, although the brightness of display panel carries
Rise, but it is smaller to lift amplitude.When α=3 °, the brightness of display panel, which has, to be more obviously improved.Therefore, the present invention is implemented
Example sets 3 ° of 1 °≤α ＜, can lift the contrast of display panel, lifts display quality.It should be noted that strip shaped electric poles portion
Bearing of trend and line direction angle α it is unsuitable too small, otherwise can influence the deflection of liquid crystal molecule in display panel, therefore α
Minimum value is 1 °.
Similarly, the bearing of trend in strip shaped electric poles portions is set and the angle of column direction is β, 3 ° of 1 °≤β ＜, equally can be effective
Lifting display panel contrast, lifted display quality.The embodiment of the present invention will not be repeated here.
It should be noted that Fig. 3 into Fig. 8, only illustrates the bearing of trend in strip shaped electric poles portion 60 and the angle of column direction
For β, 3 ° of 1 °≤β ＜ embodiment.
