Is it super standardised, like where all 30 or 40 pin LVDS connections are the same, as in pin and voltage compatible?
Are there hardware peripherals in a microcontroller that just drive LVDS like how UART, SPI, CAN, etc. work? Or is it a messy complicated thing with display specific power supply voltages, and unique power management requirements, baud rates and such?
I can find lots of old style monitor to HDMI or VGA conversions for an old laptop screen based on display model number. But what I am looking for is a USB-C/USB-3 to LVDS converter board small enough to fit into an old apple laptop top shell and act as a second monitor with all power and functionality controlled through the USB interface. I have the fab skills. If there is a simple chip that does USB-C PD/display to LVDS, I’ll toss it in KiCAD and etch it myself if I can get the chip. In my past experience with small displays for hobby microcontrollers, they were anything but standard in most cases. I have never messed with the larger stuff though. It appears like most of the old style VGA/HDMI converter boards are mostly sold with the same hardware/board with the proper LVDS connector installed.
I can take care of the backlight driver part. I’m mostly concerned with what is going on with LVDS in practice. Anyone familiar with the subject on Lemmy?
LVDS is just a standard for pairwise low voltage differential signaling. You still need a protocol on top of that to talk to the video controller.
Yeah it looks complicated. I’m seeing lots of FPGA projects in skimming around.
Yeah, it’s good for high frequency communication because its more resilient to noise and capacitive interference.
