Small transverse shifting.After many times voltage cycle, after the display for especially carrying out same picture for a long time, ion
The transverse shifting energy accumulation of residual, which reaches, to a certain degree, can cause ion towards the big pixel edge movement of high-low voltage difference simultaneously
And accumulate.In practical operation, when liquid crystal display device is showing same picture for a long time, it is different to then switch to another
After picture, the image of a picture can be indistinctly remained on panel, the edge of high contrast images is especially formed at, influences its side
Edge display effect.
When ion, which gathers, is enough to influence to drive the electric field of liquid crystal molecule, it can change the penetrance of liquid crystal pixel, lead
Cause light that display color uneven phenomenon occurs when passing through pixel.Now carry out display picture switching, then it is aggregated from
Son can not leave alignment layer surface at once, and liquid crystal display panel can be made to show that the image of different penetrances is residual in ion habitat
Stay.
