Problems solved by technology

Although the thin film transistor is not conducting, the capacitive coupling between the data line and the pixel electrode will also affect the holding state of the pixels D1-Dn in the rows G2-Gm, thus causing vertical crosstalk on the display screen
Moreover, the above problems are exacerbated when the resolution is higher
