Only have blue light during display to pass through.Fig. 4 is display screen bending area generalized section, when display screen bends, at water
Square upwards can gradually produce relative shift (shift) toward the right and left, therefore can make the black in colored filter substrate
Matrix B M is relative to the data wire generation relative displacement in thin-film transistor array base-plate, and now blue B data line is with green
Can induce an electric field E between G color filter film, the intensity of induction field E depends on blue B data line input letter
Number virtual value (RMS value).
As shown in Table 2, wherein, form dash area represents that pixel is on state of, and form non-shaded portion represents that pixel is dark
State, with from the point of view of the signal input that the dot structure the 6th of 2RGB × 4 arranges, input signal is B (bright) R (secretly) G (secretly)
B (bright), the input signal of B data line and virtual value such as Fig. 6 thereof when the pixel arrangement mode of motion shows ethereal blue picture
Shown in.Oscillogram according to input signal draws the 1/3 of the peak-to-peak value that virtual value is input signal of electric field E, according to figure
V-T curve shown in 7, the transmitance that now voltage of electric field is corresponding seldom has light can pass through, the most greatly
Reduce greatly the degree of light leak.
