First of all my apologize for long silence – I just returned from China trip with positive news. Our 7″ touch-panels has been finally re-done, and yesterday was shipped from factory to us. I bring several pcs samples with me, will make photos for you tomorrow in office.

Batch shipment is expected to reach us next week, then we will bond them with LCD panels and add our electronic board. After that we will proceed with shipments.

UPDATE: here is photo of touch sample that we bonded to LCD panel. It fits perfect! That’s open-frame version, black frame version will make tomorrow.

Delay with 7″ LCD shipping

Not very good news for us guys – we are forced to postpone shipping of our new 7″ LCDs. Electronics is ready and assembled, LCDs are already in our office. But touch-panel factory made mistake with drawing – as a result we have vertically mirrored frame of touch panel and can’t bond it with LCD panel. Here are some photos that can explain it better (click on photo to get full resolution). Yellow color is back-side of panel with adhesive tape for bonding with LCD panel. Black color framed panel has the same mistake.

I’m currently out to China to touch-panel factory to do all the best to reduce lead time of re-done batch of panels from standard 4-6 weeks down to couple weeks. Currently, we found with supplier the way to reduce it to 3 weeks.

We take full responsibility for this delay, but can’t do too much to ship panels in April, therefore we want to offer the following:
1. Any request for money return will be immediately executed.
2. For those who is OK to wait for delivery we want to offer one of the following:
– free add-on of ambient light sensor, mini USB cable, micro HDMI cable, audio adapter and power adapter (please, mention your plug type) to your order
– or free upgrade from standard shipping to DHL
– or 15% individual coupon for any future purchase in our store

Drop e-mail to our sales team (sales@) with your order # and selected action.
