In each selection period in which three scanning electrodes 312 are selected, a signal-electrode driving circuit 250 compares a bit string in accordance with the column elements corresponding to the selection of the scanning pattern with each of bit strings, which consists of a bit in each position of pieces of gray-scale data D for three pixels at the intersections of a signal electrode 212 and the three scanning electrodes 312, and conversion data Dt is generated in accordance with the comparison results.

信号电极驱动电路250在选择3条扫描电极312的各选择期间，将扫描图形之中与对应于该选择的列的要素相对应的位列，与将对应于信号电极212与该3条扫描电极312的交叉点的3个像素的灰度数据D中包含的由各位的位构成的位列进行比较，生成对应于该比较结果的变换数据Dt。

My top five works of art for Valentine's Day are a bit soft-centred, some might say, a bit corny and a bit cliched even - but that's Valentine's Day for you.

有人可能会说我的《四件情人节最不可错过的艺术作品》有点儿不够刺激，甚至有点儿陈腐，有点儿老一套，但这就是情人节。

For signed-bit values, if the number to be encoded is positive, an extra bit is necessary to preserve the leading 0; otherwise sign extension changes the bit value into a negative number.

对于带符号的位值，如果这个编码长度能够确定，一个扩展位必须保留第一位是0；否则，符号扩展将改变这个位值为负数。

But this is impossible, as long as it is engaging in a market economy, there are risks in any operation.

但是，这是不可能的，只要是搞市场经济，是有风险的任何行动。

We're on the same wavelength.

我们是同道中人。
