Claims

[Scope of utility model registration request]

In a liquid crystal television that displays images by scanning by adding one pulse to 1H every horizontal period, the panel 5 is equipped with a gate driver 6 that supports the horizontal period H to which a control signal of the horizontal period H is input. Horizontal periodic control pulse train 2 with interlacing, in which a clock pulse and a second clock pulse given a time difference through a delay circuit are combined in an OR circuit.
is input, and the horizontal periodic control of every other gate is performed in the pre-screen period, while in the post-screen period, the horizontal periodic control pulse train 2 with skipping is given to the driver 6, which is shifted by 0.5H, and the pulse train is skipped in the previous period. An interlaced enlarged screen LCD television characterized by applying an interlacing method to a liquid crystal television by sequentially controlling the horizontal period of gates.
