Hi, could you please explain me these sentences? I mainly dont know what DC bias means.
And I exactly dont understand this part " Ideally, over time, the pixel experiences a net dc bias of zero. This is important because minimizing the dc bias over time reduces the chance of image retention"
Whole article is here: www.en-genius.net/includes/files/avt_092109.pdf
Alternating a high and low VC across the pixel allows the liquid crystal to experience opposite polarities (referenced to Vcom). Ideally, over time, the pixel experiences a net dc bias of zero. This is important because minimizing the dc bias over time reduces the chance of image retention or screen burn-in, which ultimately leads to a diminished life span of both the pixel and panel.
Thanks for advices
