Abstract:
1. 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 including a resistor and a thermistor for 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 supplying to a gate line a voltage varied according to the controlling signal to drive a gate line, thereby reducing a width of a current path from a data line to a liquid crystal cell at each intersection between said data line and said gate line as said ambient temperature increases and widening said with of said current path from said data line to said liquid crystal cell as said ambient temperature decreases; wherein said gate line controller connects between said voltage converter and said gate line driver.
