Under the existence of vertical electric field E, polyreaction is produced by making blue phase liquid crystal LC and polymerization single polymerization monomer M, contribute to the blue phase liquid crystal layer after making polymerization 130 and there is the preferably tropism such as optics, thus effectively can reduce the dark-state light leakage phenomena that blue phase liquid crystal layer 130 produces because of its architectural characteristic.In addition, by making blue phase liquid crystal LC and polymerization single polymerization monomer M produce polyreaction under the existence of vertical electric field E, the problem of the dark-state light leak of the edge improving protuberance is also contributed to.
Please refer to Fig. 4 A, easily cause liquid crystal torsion because of reciprocation between the blue phase liquid crystal LC that contiguous protuberance P edge is arranged and protuberance P, the blue phase liquid crystal LC causing contiguous protuberance P edge to arrange also has optical anisotropy in the absence of an electric field.As shown in the figure, these major axis with optically anisotropic blue phase liquid crystal LC are substantially parallel to the bearing of trend of protuberance P, therefore the light beam of backlight module (not illustrating) may, by these blue phase liquid crystals LC deviation, cause display panel to there is the problem of dark-state light leak in the edge of protuberance P.
The present embodiment produces polyreaction by making blue phase liquid crystal LC and polymerization single polymerization monomer M under the existence of vertical electric field E, the blue phase liquid crystal LC that contiguous protuberance P edge is arranged can be reversed, make it have in the absence of an electric field to level off to the iso characteristic of optics (as shown in Figure 4 B), thus there is the problem of dark-state light leak in the edge improving above-mentioned protuberance P.
The torsion degree of the blue phase liquid crystal LC that contiguous protuberance P edge is arranged can be relevant to the size of potential difference (PD) V ', and determine that the method for the size of potential difference (PD) V ' can be included in before light source LS irradiation blue phase liquid crystal layer 130, size by modulation potential difference (PD) V ' draws the penetrance that display panel is corresponding, then determines the size of potential difference (PD) V ' according to the height of penetrance.The tropisms such as penetrance is lower, then the optics of the blue phase liquid crystal LC of representative contiguous protuberance P edge setting get over ideal, and the effect of improved dark state light leak is better.Fig. 5 is the potential difference (PD) of the first electrode layer and the second electrode lay and the graph of a relation of penetrance.As shown in Figure 5, when potential difference (PD) V ' is greater than 0 and is less than or equal to 5 volts, can the problem of improved dark state light leak.Further, when potential difference (PD) V ' is between 2 volts to 3 volts, the effect of improved dark state light leak is the most remarkable.When comparing polyreaction with table one below with/without applying potential difference (PD) for the impact of dark-state light leak, do not apply the sample of potential difference (PD) when wherein comparative example is polyreaction, and when experimental example is polyreaction, be applied with the sample of the potential difference (PD) of 2.5 volts.From following table, applying potential difference (PD) during polyreaction can improved dark state light leak effectively, and promotes contrast.
