This project is LVDS converted to HDMI. It has possibility to connect laptop screen to HDMI port (micro HDMI port). Board is only responsible for converting vide signals. It does not have possibility to power LED for backling
What it CAN do:
* convert LVDS signals with 2 different standards: VESA and JEIDA
* it works with laptop screens up to 27 inches
* it has possibility to swich power of laptop screen (3.3V or 5V) - by inernal jumper
* it has microHDMI port
* it has internal EEPROM for storing monitor data (you can program what will be shown by your computer in system settings.
* it has possibility to send brightness info via HDMI internal I2C to distrubute further
* it has debug ports
* it has I2C port as extension of internal I2C- you can pass brightness data to LED power board (comming as separater project) or whatever you want
* small size: 75mmx43mmx5mm
Hi guys, Thanks to courtesy and cooperation with @PCBWay Official we got new black solder mask PCBsfor both types of LVDS to HDMI converters. Additionally, @PCBWay allowed us to order a backlight converter PCB (there is no project listed on Hackaday now) which is a complementary project for driving LCD matrix from an HDMI port. More on that project soon.
PCB looks the same but wiring is different between LVDS and HDMI converters. In most cases, you will have just one standard VESA which is most common but some LCDs also uses JEIDA.
Backlight converter PCB 's:
As I mentioned it's not listed yet on Hackaday but the backlight is fully configurable via I2C port and can be driven via HDMI I2C bus. It can support different setups of LED backlights with different currents and voltages. More about this project soon.
Just published project information. We have working solution for both JEDA and VESA and its working as real project. Right now I redesing it to work as custom board and can be used separately without backling board which is much bigger in size. In next few weeks I will record working example videos.
