Hi
We have been getting some information on a FSTN LCD display we need, rarthe= r small, 20mm x 30mm. It is for an industrial product with 10years lifetime
The problem is when we specify a resolution of 64x64 pixels, the Y pixels a= re access by the LCD controller by routing on either side of the display do= ts (on the left and right side). But, this routing occupies space, so havin= g a display of 20mm outer dimension (x) actually only have an active area (= visible dots) of 12mm
So, I am trying to see if this is real or just from the manufactor we have = contacted. Anyone have worked with LCD and specs that can verify this? (tha= t the active area is reduced that much). We could reduce the number of y pi= xels, that will cause less routing and larger active area, but then the dis= play looks crude....
Also, maybe another alternative display?
Sofar we have gotten the feedback, that TFT is to expensive (and have probl= ems of availability due to sourcing to the mobile industry), CSTN (Color ST= N) is old tech and is obsolete shortly, OLED has very low lifetime (3 years= ).
Thanks
