Extend a Touch Display¶
LattePanda officially released 7" touch display and 10" IPS high resolution display for LattePanda 1st gen product line. We are also working with several parnters to deliver customized displays for commercial market, which are not available for the retail, like 3.97", 8", 11.6" and so on.
When tinkering hardware, reviewing your hardware connection is always the most important step before powering on the whole system!
Please connect it with LattePanda BEFORE power-on. And make sure the Golden Finger face the right side. The contacts on FPC are so compact and in order. Please be careful that any dislocation connection may cause the LattePanda short circuit and the IPS display abnormal like ghosting or flicker.**
Steps for connecting official 7" touch panel and MIPI display¶
- Lift up the actuator. Use thumb or index finger might be easier.
- Insert display FPC in.
Place Golden Finger side down!**
The FPC must be fully inserted in the connector. If not fully inserted, the actuator will not close properly. Should this be the case, lift up the actuator and repeat the process (starting with Step 1 above)***
- Rotate down the actuator until firmly closed.
- Insert the FPC of touch panel in Same as the display. Place the Golden Finger side down too.
