LVDS Controller Box

LVDS Controller Box This box requires a larger 3D printer, measuring about 192mm in width. Cables to VDU MONITOR and Back light in VDU MONITOR must be extended using these boxes. The design will also allow the Back Light control PCB to be fitted, with some potential tweaking required. Files include: Main_Box_LVDS_Controller_Box__Backlight.stl Back_Plate_LVDS_Controller_Box__Backlight.stl Seven_Buttons_LVDS_Controller_Box__Backlight.stl Stand offs for small speakers have been added, but these speakers do not sit flush against the inside surface. These speakers have led to changes in Back light standoff, ensuring a secure fit.

LVDS is a type of differential signaling system that transmits information by comparing the voltages on two wires at the receiver. In typical implementations, a transmitter injects 3.5 mA into the wires, with current direction determining digital logic levels. A termination resistor of about 100 to 120 ohms is used at the receiving end, matched to the cable's characteristic impedance to reduce reflections. The voltage difference across this resistor is approximately 350 mV, which the receiver senses to determine logic levels. LVDS reduces electromagnetic noise by creating equal and opposite current flow in two tightly coupled wires. This noise reduction occurs because the equal and opposite electromagnetic fields tend to cancel each other out. Additionally, tightly coupled transmission wires reduce susceptibility to electromagnetic noise interference, as common-mode noise will equally affect both wires. The LVDS receiver is unaffected by common mode noise, as it senses differential voltage, not affected by common mode changes. https://en.wikipedia.org/wiki/Low-voltage_differential_signaling This design is a remix of the LCD controller case V29, V59 found at http://www.thingiverse.com/thing:1166506 Print Settings: Printer: Protomaker Sprint Rafts: No Supports: No Notes: This box requires a larger 3D printer due to its width of approximately 192mm.
