Printed circuit board and liquid crystal display device having the same
View Patent ↗An LCD capable of preventing and electrostatic discharge is provided. The LCD includes a liquid crystal panel for displaying an image, a PCB on which electronic devices are mounted to generate signals for driving the liquid crystal panel, and a protective pattern formed around an electronic device of the electronic devices, which is vulnerable to an electrostatic discharge.
1. A liquid crystal display device (LCD) comprising:
a liquid crystal panel for displaying an image;
a printed circuit board (PCB) including a ground pattern and a solder resistor formed thereon and having electronic devices mounted thereon to generate signals for driving the liquid crystal panel; and
protective patterns formed around an electronic device which is vulnerable to an electrostatic discharge separating the vulnerable electronic device from other electronic devices, wherein the protective patterns have a plurality of patterns formed by the ground pattern exposed to the exterior by partially removing the solder resistor around the vulnerable electronic device.
2. The LCD according to claim 1 , wherein the electronic device vulnerable to the electrostatic discharge is a variable resistor.
3. The LCD according to claim 1 , further comprising a plurality of signal patterns formed on the PCB.
4. The LCD according to claim 1 , wherein other electronic devices are adjacent to the electronic device vulnerable to the electrostatic discharge having the protective patterns interposed therebetween.
5. The LCD according to claim 3 , wherein the protective patterns guides the electrostatic discharge to the ground pattern.
6. A printed circuit board (PCB) comprising:
a substrate including a ground pattern and a solder resistor formed thereon;
an electronic device mounted on the substrate and vulnerable to an electrostatic discharge;
other electronic devices mounted on the substrate; and
protective patterns formed around the electronic device which is vulnerable to an electrostatic discharge separating the vulnerable electronic device from the other electronic devices,
wherein the protective patterns have a plurality of patterns formed by the ground pattern exposed to the exterior by partially removing the solder resistor around the vulnerable electronic device.
7. The PCB according to claim 6 , wherein the electronic device vulnerable to the electrostatic discharge is a variable resistor.
8. The PCB according to claim 6 , further comprising a plurality of signal patterns formed on the PCB.
9. The PCB according to claim 6 , wherein other electronic devices are formed adjacent to the electronic device vulnerable to the electrostatic discharge, with the protective patterns interposed therebetween.
10. The PCB according to claim 8 , wherein the protective patterns guides the electrostatic discharge to the ground pattern.
