Hi shabaz

Could you tell me whether we can connect the lcd display of laptop with cell phone's mother board (like iPhone 4s) directly from the cell phone's display port.

Please share your suggestion

Does anyone have more information about this SU-040-X01 Digitizer? I am trying to hack it fur use on a Raspberry PI 2 but I can't find any information on it.

I figured out where the power is on pin 13 and ground on 1 and 14 however i am trying to figure out what the other four wires are, when it's powered it reads 3.3, 2.3, 0 and 3.3 across those pins. I am assuming that it is for RX/TX and probably some way to tell the computer it's ready? or clock signals? Not sure - based on that description (it's a little vague i know) can anyone guess as to how I might read data with an arduino or PI 2? I am guessing I will need to use a serial library but I am not even sure of that...[View:/resized-image/__size/510x402/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-0b9cdafb-c30b-4b2c-9096-56207ea34fbc/contentimage_5F00_176781.png:510:402]

Hi, thank you this detailed guide. It was long searching for a platform allowing me to develop and apply hybrid apps under android (Cordova/Phonegap/Ionic). There are multiple very cheap single-board-computers with different quality of hardware support, driver support or Android availability. 99% of them does not support LVDS and 99%of them support only 16:9 resolution on HDMI.

I have a couple of old 15"-17" LCDs and I bought also some cheap LVDS-HDMI boards, but I stuck at stretched output picture due to unsupported resolution on HDMI output. I was very happy to discover the riot board with (hopefully) good Android and LVDS support.

Although this thread seems to be fairly old I would be very happy if someone could clarify some of my questions:

Why do I have to use separate circuit board to power up the LCD ? The LVDS (Mini DVI) interface supports 3,3V and 5V, The second can be used to power 5V inverter. I can also use the 3,3V and %V from the 40pin connector. The manual also mentions Backlight enable and PWM pins
Does it make any sense to connect the I2C_SC/ I2C_SDA pins to the corresponding pins on the LCD ? Usually EDID information is transmitted over those, but i do not know if riot board can use this information.
Which resolutions are supported over the LVDS interface ? In the manual is WUXGA mentioned.@ !

Hi Shabaz,

I'm newbie in doing this kind of project so hoping that you can guide me on the wiring as it's not that clear from the picture. As per the mini-HDMI LVDS schematic this is what I think the wiring is

LCD Panel miniHDMI breakout *********** *******************RIN0- Pin 9RIN0+ Pin 8

RIN1- Pin 6RIN1+ Pin 5

RIN2- Pin 3RIN2+ Pin 2

RCLKIN- Pin 12RCLKIN+ Pin 11

Please correct me if I'm wrong.

Thanks

Great post.

I like the detail on the connectors and the breakout board.

Oh, and that connector looks a lot like the one on my panel.. I assume it's standard much like the lvds interface itself..

does your inverter allow for brightness control, and if it does did you try it ?
