[0063] The second embodiment:
[0064] In the second embodiment, a pair of low-frequency pulse signals applied to the row and column electrodes in the full-screen dynamic frosting operation are as Figure 5A Shown. in Figure 5A In the above waveform, the low-frequency pulse signal applied to the row electrode is composed of x pulse groups. The number of pulse pairs in each pulse group is the same, which is Nf, and the frequency of each pulse group is the same. It is 1 / Tf, and the voltage amplitude of each pulse group is different, the voltage amplitude of the first pulse group is UR1, the voltage amplitude of the second pulse group is UR2,..., the voltage amplitude of the last pulse group For URx, UR1> UR2> ……> URx. in Figure 5A In the waveform diagram below, the low-frequency pulse signal applied to the column electrode is opposite in phase to the low-frequency pulse signal applied to the row electrode and the voltage amplitude of the waveform as a whole is different.
