Hello everybody
Anybody knows which display has been used in the video onYouTube “Toradex - Fast Boot demo with Linux and Qt”?
Thx
Hello Savino,
we are looking into this. What brand and type we have been using.
Best Regards,
Matthias
Dear @savino
Sorry for the delayed answer.
The display was a KOE TX31D200VM0BAA:
However, it can be tricky to get it depending on where you live.

What LVDS cable was used to connect the display to the carrier board and was a controller board required
Hi @Waunye11 , only an LVDS cable is required to connect the display to the Ixora carrier board. Here is the LVDS interface on Ixora.
Is there a part number & brand for the cable used. There are many lvds cables with different pinouts or would I need to terminate the wires myself?
I am afraid that you have to terminate the cable yourself.
In that case what is the name of the female lvds connectors & what gauge wire should I use?
Hi @Waunye11 ,
In that case what is the name of the female lvds connectors
I assume you are referring to the LVDS interface on our Ixora/Apalis Evaluation board. That connector is Hirose DF13A-40DP-1.25V(55). Its mating connector is DF13-40DS-1.25C.
what gauge wire should I use?
Here is my cable.
Okay great! What about the male connector for the KOE displays LCD interface and Backlight interface ? The receptacle for the lcd interface is a JAE FI-SEB20P-HF13E and the receptacle for the backlight interface is a JST SM02(8.0)B-BHS-1-TB
Hi @Waunye11 !
Could you please share your Display datasheet?
It might need not be as straightforward as attaching an LVDS connector. LVDS is not standard for the pinout and the Backlight voltage might not be compatible, so you might need some circuitry to convert/adapt it.
Best regards,
Henrique

Hello Waunye11,
do you still need some help here?
Did you build you custome cabel yet?
Best regards,

I have the the cable and connectors now apparently the cable is just an hdmi cable with different connectors
ok let us know if you need help.
Best Regards,

Based on the KOE datasheet what pins should I connect to which pins on the Ixora Carrier boards lvds connector?
Also is there a recommended cable length for connecting the display to the carrier board? Is there a max length before the signal starts to degrade?
The VDD Pin 1 and 2 from the display should be connected to Ixora X19 Pin 32.
The Pins (3, 4) should be connected to Ixora X19 Pins17,23
You need to connect
Display IN0 - to Ixora LVDS1_A_TX0_N
Display IN0 + to Ixora LVDS1_A_TX0_P
…
Display IN3 - to Ixora LVDS1_A_TX3_N
Display IN3 + to Ixora LVDS1_A_TX3_P
Display Clk In - to Ixora LVDS1_A_CLK_N
Display Clk In + to Ixora LVDS1_A_CLK_P
Also connect all Display GND pins located near data pins to GND pins on Ixora connector located near same Data pins,
For Example
Display CN1 pin 7 to Ixora X19 pin 20
Display CN1 pin 10 to Ixora X19 pin 14
etc
Further all the Pins LVDS1_B_xx can be kept unconnected.
And the Pin 20 from the display (DIM )should be connected to Ixora PWM_BKL1 .
Finally for the backlight, you need to connect Display CN2 Pin1 to Pin 39/40 of the LVDS Connector on Ixora
and Display CN2 Pin 2 to any unused GND pin of the LVDS Connector on Ixora.
Maximum cable length depends on frequency (defined by resolution and color depth), cable quality, and environment. Keeping the cable length under 2 meters (about 6.5 feet) is often advised to avoid signal degradation.
For any further questions regarding your display connection, please create a new thread and avoid reopening old threads, especially those not created by yourself.
