Below with described adjustment structure for polarizer specifically introduces the displaying principle of lighting display device.
Such as, one row (column) display bore hole information (namely in the information that the observer of indoor sees), one row (column) display polaroid signal (information that the observer namely in outdoor is seen by the polaroid (analyzer) be arranged on transparent wall), one piece of polarizer is placed before liquid crystal panel, odd-numbered line λ/4 postpone, even number line-λ/4 postpone, such polarizer λ/4,-λ/4 postpone alternately, produce left and right circularly polarized light, as shown in Figure 4, in figure, pixel drive signal 10 forms the cextrorotory circularly polarized light 30 of the left-handed circularly polarized light in phase delay direction and phase delay side after polarizer 20 carries out the adjustment of polarization direction.
If the data A that the outdoor observer of odd number behavior watches, the data B of even number behavior indoor observation person bore hole viewing.
If outdoor observer watches data by the analyzer (analyzer is can pass through the rotatory polarization sheet that phase delay direction is left-handed circularly polarized light) be arranged on transparent wall, data message be A1, A2, A3,,, An (wherein An is certain odd row data);
If indoor observation person bore hole viewing data message be B1, B2, B3,,, Bn (wherein Bn is certain even number of lines certificate);
If offset data be C1, C2, C3,,, Cn (wherein Cn is certain even number of lines certificate);
If the black constant value data of odd-numbered line are A0;
If the black constant value data of even number line are B0;
Only see for realizing indoor bore hole data message B1, the B2 of normal display, B3,,, Bn, and only see in outdoor A1, A2, A3,,, An, the present invention does following setting to data-driven of the present invention:
