LVDS Controller Box
This is about 192mm width so a larger 3D printer is required.
PLEASE NOTE Cables to VDU MONITOR and Back light in VDU MONITOR will need to be extended using these boxes.
Design that will also allow the Back Light control PCB to be fitted, may still need some tweaking. Files :-
I have just added some stand off for small speakers, these speakers do not go flush against the inside surface.
The speakers have made other changes Back light standoff so the speakers should fit.
Here is a YouTube Play list relating to this
Low-voltage differential signaling, or LVDS, also known as TIA/EIA-644,.
LVDS is a differential signaling system, meaning that it transmits information as the difference between the voltages on a pair of wires; the two wire voltages are compared at the receiver. In a typical implementation, the transmitter injects a constant current of 3.5 mA into the wires, with the direction of current determining the digital logic level. The current passes through a termination resistor of about 100 to 120 ohms (matched to the cable's characteristic impedance to reduce reflections) at the receiving end, and then returns in the opposite direction via the other wire. From Ohm's law, the voltage difference across the resistor is therefore about 350 mV. The receiver senses the polarity of this voltage to determine the logic level.
As long as there is tight electric- and magnetic-field coupling between the two wires, LVDS reduces the generation of electromagnetic noise. This noise reduction is due to the equal and opposite current flow in the two wires creating equal and opposite electromagnetic fields that tend to cancel each other. In addition, the tightly coupled transmission wires will reduce susceptibility to electromagnetic noise interference because the noise will equally affect each wire and appear as a common-mode noise. The LVDS receiver is unaffected by common mode noise because it senses the differential voltage, which is not affected by common mode voltage changes.
