Taobao offers are way lower than Aliexpress offers and payment is an issue though. Most shops requires the chinese version of paypal (zhifubao or their bank alliance card / account) to do business.

In the end, for the handful I had contacted, the advertised offers are the "best case" scenario for a job. I.e. static or 4-mux (simple routes), "watch" size design (little ink, little glass), zebra contacts (no pin cost).

I am not ready to try Taobao sellers as they are mostly setup for local Chinese shoppers and I will need some kind of proxy which sounds trouble for custom projects.

Well I'm in Zhejiang so it's my pleasure to offer any help. (Communication, payment, shipment, etc.). (Errrr but I'd rather accept bank transfer instead of PayPal... You see... Zhifubao is totally free while PayPal charges exorbitant fees...) (My father's company account can accept dollar)

One of my friend, also a member of this forum, Andy Lilitha, is in Shenzhen. But he is in Junior Three now so I doubt if he is available these days... The good news is that he may know those small electronic factories well.

Waon, if you frequent Taobao and would like to help "poking" potential suppliers, here is the specification I used when asking for quotes. I know Chinese but have few uses of it for the past 15 years so it is difficult for me to do search / communitions w/ Taobao sellers. OTOH aliexpress shops are OK w/ English.

1. New Design
2. Dimensions about 66mm x 16mm, see attached drawing.

. digits looks like this, 14+3 segments.
. the whole display is like this, as in the calculator, note the 'G' and the 'RAD' are 2 icons. The 0, 1, 2, 3, 4 are also independent icons.
<<< attach drawing that you uploaded >>>

3. Connection: PIN, 0.1"
4. LCD Mode: TN Positive
5. Polarizer Type: Reflective
6. Temperature Range: Indoor -10 to +60
7. Type of Application: Calculator
8. Quantity: 1st batch 100, may have 100-200/yr afterwards.
9. Shipping Information: Toronto, Canada.

The controller I am using (a TI MSP430FRAM MCU w/ LCD segment driver), w/ controls

6-Mux, 6:00, 1/3 Bias, 3V.

If you can find potential manufacturers that might take smaller orders ($1k inclusive for 50-100 units), I can start the process of working out the details.

Thanks and if anyone has other leads / suggestions, they are all welcomed.
