Problems solved by technology

[0015] However, the optical response of some liquid crystal materials from light to dark is slow, and the optical response value has not yet reached a low enough value during the above-mentioned black line scanning, so it is inevitable that a few of them will still produce a little "afterimage" overlapping blur between pictures The phenomenon
