Page 2: How To Proceed
Introduction Designed for LCD monitor and other flat panel display applications the SVP-1280 controller provides an auto-input synchronization and easy to use interface controller for: TFT (active matrix) LCD panels of 1280x1024, 1024x768, 800x600 and 640x480 resolutions; Computer video signals of VGA, SVGA, XGA and SXGA standard. -
Page 3: System Design
A typical LCD based display system utilising this controller is likely to comprise the following: Summary: LCD panel LCD controller card, SVP-1280 LCD panel connector board for LCD signal cable (if necessary) LCD signal cables Inverter for backlight (if not built into LCD) -
Page 4: Assembly Notes
ASSEMBLY NOTES This controller is designed for monitor and custom display projects using 1280 x 1024 or 1024 x 768 resolution TFT panels with a VGA, SVGA, XGA or SXGA signal input. The following provides some guidelines for installation and preparation of a finished display solution. - Page 5 • Controller Mounting: It is recommended that a clearance of at least 10mm is provided above and 5mm below the controller when mounted. Additionally consideration should be given to: • Electrical insulation. • Grounding. • EMI shielding. • Cable management. Note: It is important to keep panel signal cables apart from the inverter & backlight cables to prevent signal interference.
