Device for integrating LCD monitor circuitry
View Patent ↗A device for integrating LCD monitor circuitry to improve the productivity and reduce the cost of manufacturing LCD monitors are disclosed. The device of the invention comprises: a power converting circuit, providing power required by the LCD monitor circuitry; a back-light driving circuit, providing a driving signal required by a LCD back-light module; and an image processing circuit, processing an image signal for LCD displaying; wherein said power converting circuit, said back-light driving circuit and said image processing circuit are integrated on a single-layered printed circuit board (PCB).
1. A device disposed on a panel module of a LCD monitor, comprising:
a power converting circuit, providing power to said LCD monitor;
a back-light driving circuit, providing a driving signal to a back-light module of the LCD monitor; and
an image processing circuit, processing an image signal for LCD displaying:
wherein said image processing circuit comprises a DiP-type image controller and a micro-controller performing analog-to-digital conversion and magnification or reduction of said input image signal;
wherein said power converting circuit, said back-light driving circuit and said image processing circuit are disposed disposed on a single-layered printed circuit board (PCB) disposed on the panel module.
2. The device as recited in claim 1 , wherein said power converting circuit converts an input alternate-current (AC) voltage source into a low-voltage direct-current (DC) output.
3. The device as recited in claim 1 , wherein said driving signal from said back-light driving circuit is high-frequency and high-voltage.
4. The device as recited in claim 1 , further comprising an audio processing circuit performing magnification or reduction of an audio signal.
5. The device as recited in claim 3 , wherein said back-light driving circuit provides an AC driving signal having higher frequency by frequency conversion so as to drive said LCD back-light module.
