detailed description

The inventors found that, as shown in Figure 1, the VT (that is, driving voltage-light transmittance) curve a of the first pixel (that is, the R pixel, corresponding to the red color resistance on the color filter substrate) is the same as that of the second pixel ( That is to say, the VT (drive voltage-light transmittance) curve b of G pixel, which corresponds to the green color resistance on the color filter substrate, basically coincides (especially, under the same drive voltage, curve a and curve b reach almost simultaneously The peak, that is, the peak of the curve a and the peak of the curve b are located on a straight line parallel to the y direction, and the peak of the curve a and the peak of the curve b almost coincide, that is, under the same driving voltage, the R pixel and the G pixel are almost At the same time, the maximum light transmittance is reached, in other words, the driving voltage corresponding to the R pixel obtaining the maximum light transmittance is relatively close to the driving voltage corresponding to the G pixel obtaining the maximum light transmittance), however, the third pixel (That is, the B pixel, corresponding to the blue color resistance on the color filter substrate), the peak of the VT (ie driving voltage-light transmittance) curve c is located on the right side of the peak of the curve a and the peak of the curve b, so that the curve a. Curve b and curve c do not overlap, that is, under the same driving voltage, curve a, curve b and curve c cannot reach the peak at the same time, so that when the liquid crystal display panel is displaying, under the same driving voltage, It is impossible for the three pixels of RGB to obtain the maximum light transmittance at the same time, which leads to color shift of the liquid crystal display panel.

The inventor further researched and found that the problem of color shift can be improved by providing different driving voltages for the three pixels of RGB to achieve the maximum light transmittance of the three pixels of RGB at the same time, but this method will greatly increase the number of driving circuits of the liquid crystal display panel.

The absolute value of the difference between the corresponding driving voltage and the corresponding driving voltage when the second pixel (that is, the G pixel) obtains the maximum light transmittance, that is, the liquid crystal display panel provided by the embodiment of the present invention, by reducing The third angle makes the R pixel, G pixel and B pixel achieve the maximum light transmittance at the same time under the same driving voltage, so that the color shift of the liquid crystal display panel can be reduced or eliminated, and the display quality can be improved without increasing the brightness of the liquid crystal display.
