LCD Driver Board Compatibility
The Ruth's sister cable connects LQ121S1LG55 and LQ121S1LG45 LCD driver boards inside a system. It serves builders integrating 10 to 13 inch tablet panels that use these specific board models. The part is not for installations requiring a different connector pinout or voltage rail.
Thermals Noise and Power Draw
As a passive internal cable it generates no heat and produces no audible noise during operation. Power draw is limited to the transmission losses of the conductors carrying supply current to the attached display board.
