Description of Invention (3), line. In the “scanning cycle”, the “select line per column will be selected”. The line-pair scanning method results in a brightness difference between pixels, and this bright sound will be different in the same row and the next column. The grid pixel is caused by the capacitance. In the continuous scanning mode (Progressive scanning mode) (, ^: γΑΑd " Me), as the number of scanning lines increases, the sweep period gate becomes shorter.

When selecting columns in this way, when the column selection line VG (n) * VG (n + i) drops from VGH60,61 to Vgl62,63 due to the capacitance in each display cell, The voltages VP (n) and VP (n + 1) on the pixels will change significantly. This change in voltage across the pixels can cause undesired intensity changes or inconsistencies in the displayed image. Now referring to Figure 4B, if the voltage VG (n + l) on the selection line of the n + 1th column drops from VGH61 to vGL63, the electricity on the selection line of the nth column (please read the precautions on the back before filling this page) ) '' Installed -----order ---

This row selection line 70 is connected to a data driving circuit which can provide video information to the display. As shown in FIGS. 5A to 6B, the column selection line voltage is changed between the voltage Vgh60 when the column is selected and the voltage ν ^ 62 when the column is not selected. vGH is between approximately 15 volts and 30 volts, and Vgl is between approximately -10 volts and -6 volts.

An embodiment in which four lines are selected at the same time is useful for the difference of using two gate scan driving circuits in the figure. The LIU device is particularly shown in reference # 7A and 图 7B, which shows a large (non-woven) example for driving a thin film transistor liquid crystal display below. In Figure 7A, in addition to the other two implementations in the first place, α A except the first in the first field-two columns of selection lines are selected at the same time, and in Figure 7B, except in the first field Outside of the first and second scan periods, the same-time selection-selection line is selected. As shown in Figure 7A, the selection mode voltage continues to ϋ 2nd and 3rd; 3rd and 3rd and 6th: 6th and 6th and 7th; ...; 476th and Mith and still. = And the 479th and the second choice line.

Description of the invention (9) and 477; 476, 477 and 478; 477, 478 and 479; and 478, 479, and 480 column selection lines. In both embodiments, when the selection line is not in the selection mode voltage, it is in the non-selection mode voltage. The embodiment in which two lines are selected at the same time is particularly useful for a TFT LCD device using two gate scan driving circuits in the first figure. Although the present invention has been shown and described with its preferred embodiments, various changes in form and detail may be made without departing from the spirit and scope of the invention, which will be apparent to those skilled in the art.
