I have an old pro audio music production device with an embedded 240x320 monochrome LCD display. The data is 4 bit. The display is monochrome.
I want to duplicate the LVDS data and add an external VGA output so that I may see the display on an external monitor in addition to the embedded LCD.
The LVDS pinout is as follows:
| 1 | FLM | First Line Mark / Shift Direction Select |
| 2 | M | Alternation Control Signal |
| 3 | CL1 | LP, data latch (row) / Display Data I/P Clock |
| 4 | CL1 | CP, data shift (column) / Display Data I/P Clock |
| 5 | DISPOFF | Controls Display off, 0: off, 1: on |
| 6 | D0 | Data Pin |
| 7 | D1 | Data Pin |
| 8 | D2 | Data Pin |
| 9 | D3 | Data Pin |
| 10 | VDD+5V | Power Supply 5volts |
| 11 | VSS-GRD | Ground |
| 12 | VLC-24V | |
| 13 | VO | Contrast Adjustment, usually uses POT that can source 0-5V |
| 14 | FGND |
I don't expect a 320x240 monochrome display to look pretty on an external monitor, but I just want something that is larger and easier to see.
The closest thing I've been able to find to a possible solution was suggested here: e2e.ti.com/support/interface/f/138/t/575183
Please let me know the simplest way to accomplish this. Thank you!
