Charge characteristic compensating circuit for liquid crystal display panel

A charge characteristic compensating circuit for a liquid crystal display panel including a plurality of liquid crystal cells arranged at each intersection between data lines and gate lines to control a light transmissivity in response to data signals from the data lines, and a plurality of switching devices for switching the data signals to be applied from the data lines to the liquid crystal cells in response to signals on the gate lines, the circuit, comprising:

• a voltage supply for generating a gate voltage required for the gate lines;
• a gate line driver for applying the gate voltage from the voltage supply to the gate lines to drive the gate lines;
• and
• a current controller for responding to a change in the ambient temperature to change a voltage level of the gate voltage to be applied from the voltage supply to the gate line driver.

A charge characteristic compensating circuit for a liquid crystal display panel (LCD), comprising:

• a voltage converter generating a high level gate voltage;
• a gate line controller receiving said high level gate voltage from said voltage converter and supplying a controlling signal that varies as an ambient temperature varies;
• and
• a gate line driver receiving said controlling signal from said gate line controller and driving a gate line.
