    Further details on the display used in the X108G OLED version -
    upload_2018-10-26_16-41-50.png

    The ritDisplay module has the internal project number P16803

    see here: 錸寶科技股份有限公司 - P16803


    This module has the SSD1353 control chip from Solomon Systech on it: https://www.google.com/url?sa=t&rct.../SSD1353.pdf&usg=AOvVaw1pb48EPixv8oFeyYIKfDgH

    What I think we need to confirm is that the interface from this module has the same pin assignments on the cable as the TFT one when removed from what is an Arduino compatible board. Otherwise it will not be a simple exchange of the unit.

    I'm hoping the SPI Interface may define what the pins need to be as both displays support SPI (serial peripheral interface?).
    ( Serial Peripheral Interface - Wikipedia ).

    The cable from what may be the display used in the X108G has 45 connections:

    Hi Guys thanks for all the info it looks like I maybe going down the wrong track but I will wait till the display has arrived and see iff it can be adapted if not may have to drop a line to RIT displays and see if they will supply to the small man. I think I will start the ball rolling now and get in touch with them. Will let you know how I get on.

    Regards

    Hi Guys

    I have contacted with this OLED display manufacturer, RiTdisplay Corporation. Tracy Yang (tracyyang@ritdisplay.com) forwarded me to a reseller at USA US Micro Products | Engineered Display Solutions but seems they don't have part number.

    At the Xiegu X108G/X5105/G1M/G90 facebook group, a guy posted the pics about the display replacement that he performed. In those photos you can see a number code 3121170013.

    Facebook

    Looking for "1,77 oled ssd1353" at AliExpress, I've found some sellers that offer a similar (if not the same) display.

    1.77 inch 45PIN Full Color OLED Screen SSD1353 Drive IC 160*128 (Short FPC)-in LCD Modules from Electronic Components & Supplies on Aliexpress.com | Alibaba Group

    NOTICE: The photo shown at this link, doesn't the same of actual photo inside the XIEGU 108G.

    Dave,
    While you have a damaged OLED display I believe, getting a replacement makes good sense - it could be listed under either the RitDisplay project number or the MPN in the Xiegu service manual however you will still have the problem if you wish to use this "outdoor" model outside - that if there is any level of sunshine, the display becomes unreadable and the brightness setting in the service menu has no effect whatsoever on the display (Xiegu support have confirmed this as normal). So returning to the old TFT display technology and gaining the brightness option might be a good solution.

    Does anyone know where we can get a copy of the service manual for the non-OLED model? that should then give details of which TFT display Xiegu used to use.

    If we are lucky we may find it has the same SPI interface and cable pin-out but it could also be different, in which case it's going to be a nightmare to fit.

    Thanks for the extra pictures Anibal.

    P.S. Looking at the two pictures, the OLED displays have different numbers - the one on the RiTdisplay site is 312 1168030 - the possible similar units on AliExpress are 3121170013 - which by the similarity of number could simply be either a later model or these could be just serial numbers I suppose. what DOES look different to me is the connector on the AliExpress units. But without a real close-up of both, it's not possible to say.

    Here are three versions of the OLED listed at the US company's site:
    upload_2018-10-27_8-53-49.png

    This is on this web page: PMOLED Products | US Micro Products

    What we really need is a photo of the rear of the OLED as installed in the X108G to see if the display is the one with or without the connector.

    Specification sheets of the three OLED modules are available from this page via the download button on the right, so one can check which is the correct display.

    That's the great advantage of generic LCD displays.. if you damage it , say in Sota work you don't have to search all over PRC with a knapsack to find another one. Radio has some great features but lack of replacement display near PO Purch is not one of em
