Abstract
An apparatus for controlling the liquid crystal timing has a back light driving device to provide a constant current. The apparatus for controlling the liquid crystal timing is used to control the liquid crystal display at the specific timing period.
Claims12
An apparatus for controlling a liquid crystal timing under a specific timing period, the apparatus comprising:
- a back light driving device, which includes a function for providing a power with a constant current to a back light source.
An apparatus for controlling a liquid crystal timing, at least comprising:
- a liquid-crystal timing control circuit, used for controlling a liquid crystal display under a specific timing period;
- and
- a back light driving device, which includes a function for providing a power with a constant current to a back light source.
An apparatus for controlling a liquid crystal timing comprising a timing control circuit, the characteristics which comprises:
- a back light driving device, which includes a function for providing a constant current, is combined with the timing control, so as to provide a constant current to the back light source.
