[0033] Please refer to figure 1 , figure 1 It is the circuit connection diagram of the liquid crystal display of the first embodiment. Such as figure 1 As shown, the liquid crystal display with wide and narrow viewing angle switching in this embodiment includes a timing controller 100 , a gate driver 200 and a source driver 300 . The timing controller 100 provides a first group of clock signals and a second group of clock signals. Both the first group of clock signals and the second group of clock signals include n clock signals that are evenly spaced by a phase difference in sequence. The first group of clock signals and the second group of clock signals The corresponding clock signals of the two groups of clock signals have a phase interval of 1 / 2 phase difference in the wide viewing angle display mode, while the phases in the narrow viewing angle display mode are the same, wherein n is an even number greater than 1, and a phase difference is T / n, And T is the period of t...
