  • D945GSEJT LVDS connector for LCD Panel

    Hi,


    What about the D945GSEJT LVDS connector for LCD Panel? (yes, those LCD panels used in notebooks)

    Does anybody know which LCD Panel, LCD inverter and LCD/inverter cables would work with D945GSEJT?

    I found a "White Paper" about Intel LVDS: http://www.intel.com/support/motherb.../CS-030675.htm

    I am planning to use a 15" LCD Panel.


    Thanks

    I connected my LCD CLAA089NA0ACW to the motherboard D945GSEJT

      TinyQ can you please explain how you did activate the LVDS port from the mother board because it's blocked by default and can't be activated. Or perhaps you can directly give the bios you are actually using, that will be really great. I took this motherboard for the LVDS port, but it's only after that i realize that intel don't want provide any help about it. so i am stuck with this board

        There are various reasons why Intel has this feature disabled. The mail one is that it can violate the ECC cert they obtained for the board. For them to legally sell the board here in the US they have to comply with the ECC rating. There is a DOS file that has to be run to enable the LVDS. It should be on Intels site under the product info.
        What cables and panels work is another matter. Just about any panel will work, but the connector on the panel dictates the type of cable used. We recently had to have a cable made for a panel that uses an IPEX connector. A real mother since it uses micro coax.

          I need to connect this board to a
          LP154W01 LCD,
          LVDS output as an asset?

          Greetings.

            LCD only works in WinXP after the launch of video drivers.
            driver I generated with the help of Intel Embedded Graphics Drivers are downloaded from Intel website.

            Supported operating systems
            •Windows XP* (SP3)
            •Windows XP Embedded* (SP3)
            •Windows Embedded for Point of Service*
            •Windows CE* 5.0
            •Windows Embedded CE* 6
            •Moblin 2.0 Linux kernel 2.6.29-rc2, X server 1.6.0
            •Fedora 10 kernel 2.6.27, X.org 1.5
            •Fedora Core 7* (2.6.21 – 1.3194 and X.org 7.2)
            •Wind River Linux* (kernel 2.6.21, X.org 7.2, X server 1.3)
            •Red Hat Linux* Embedded (kernel 2.6.23, X.org 7.2, X server 1.3)
            •DOS* Support (IBM PC 2000,* MS 6.22)

            using the Intel Embedded Graphics Drivers may create VBIOS, but I do not know how to flash in the motherboard
            The CED also creates a VGA.bin file, which is the Option ROM which must
            be merged with your system firmware. Contact your firmware provider for
            instructions on merging option ROMs with the system firmware.

              Hi TinyQ,

              Can you help us with some more details on what you went through to get the LVDS running?

              I have the Intel Embeded Graphics toolkit.

              What I'm wondering is if you enabled either of the other video outputs (VGA or DVI-D), and if you specified timings for your LCD panel or if it was just EDID compatible and you just used that.

              I'm trying to get a B089AW01 V1 panel working. They're usually used in netbooks and are cheaply available on auction sites and such...

              The datasheet lists the timings and all, but the panel is EDID compatible, so I'm thinking that I can just use that rather than putting them in manually...

              If you can help me generate the proper driver, I might be able to help with figuring out the flashing of the VBIOS...

                The problem with the panel you have is that it uses an APEX connector. Apex uses micro coax not traditional stranded wire. You are going to have a hell of a time getting it to work. If you get the cable worked out the proper settings for an AUO panel would be 5v for the backlight and 3.3 for the panel. Make sure you dont put 12v to the backlights or you will somke them. Been there done that.

                  Well, I've got the original wiring assembly that went from the LCD to the motherboard of the net-book, so I guess I'll start with taking that apart carefully on the Notebook side. Sounds like my lighted magnifier lamp is going to come in handy...

                  Worst case, I'll just desolder the connector from the back of the LCD and wire it directly. Tedious, but doable.

                  Any idea where to get the connector that fits the d945GSEJT board? I haven't gone through the process of sourcing that. Not sure if it's something that Mouser or Digi-Key carry or not...

                    I can tell you that it is possible to make a cable that goes from an IPEX connector to the JT inverter and LVDS connectors. I can also tell you that it took 2 engineers going back and fourth for a week or so to figure out the pin out for this cable, and one of them works for IPEX. They are also expensive to make, as in samples of it were over $60, but I dont know how much it would cost you to make one. Production pricing was better but still expensive. If I can find the email with the pin out I will post it here.
                    I only know all of this because we provided this board and panel to a customer for a project.
                    You may want to consider picking another panel that doesnt have an IPEX connector on it.

                      I ordered the connectors to the motherboard at Digikey

                      LVDS
                      Vendor: JST
                      Part Number: SHDR-30V-S-B
                      Part Number: SSH-003GA-P0.2

                      Backlight
                      Vendor: JST
                      Part Number: PHR-7
                      Part Number: SPH-002T-P0.5S

                      I used CLAA089NA0ACW instead B089AW01 because CLAA089NA0ACW better in performance and has a 30 pin connector with 1mm step
                      and it has EDID eeprom

                      In Intel Embedded Graphics Drivers i used only LVDS output with settings from LCD EDID memory

                      the only thing I could not set out PWM out for backlight

                        Thinking about using the CLAA089NA0ACW in a DOS based system. Could you post or PM the pinout for this screen.
                        thanks

                            Hello TINYQ which channel on D945GSEJT you are using.. i.e. Channel A is on Odd pin numbers.
                            1,3,5 etc.. and channel B is on Even Number side..
                            please guide...

                              Hello TinyQ

                              i have one query plz guide me....

                              which channel should i use on intel side.. i am using hannstar lcd HSD100IFW1 it has same pin diagram as chunghwa..may be the clone.... can you tell me should i use Channel A or Channel B from intel motherboard side???Channel A is on Odd pin numbers i.e. 1,3,5....29 and channel B is on even pin number side......2,4,6,8...30...

                              one mroe thing can you please upload Windows XP drivers created by you from IEGD 10. this is the same lcd so i think it will work with mine....
                              Thanks,
