MISCELLANEOUS TECHNICAL NOTES |
This video controller is for use with LCD and flat panel display applications. Adequate insulation should be used for all areas of the PCB, especially in high voltage parts such as the inverter. Settings can be controlled by an analog VR or digital function control device. |
