Hi Tsvetan, maybe you can shed some light on this.

My experience with the Olimex LCD displays is different (so far). I have got: 2* A13-LCD7-TS differing in quality (the older one having the "better" touch screen) A A13-LCD10TS and a LCD-OLinuXino-10TS. Okay those are different models, but I somehow hoped the LCD-OLinuXino-10TS would be a A13-LCD10TS + the additional ports for the lime/lime2. The A13-LCD10TS (I have) is the one that definitely needs the sensitivity adjustment. The A13-LCD10TS is matte and the LCD-OLinuXino-10TS is unfortunately glossy. @Tsvetan: does Olimex have multiple display/touch screen suppliers? did you see the quality difference with the A13-LCD7-TS, too? Can you give any "guarantees" (please don't take that in any way as a legal thing) about the quality of future displays? will they stay the same model? The LCD-OLinuXino-10TS I just got, has a "ARISING" label on the back. And finally to get really back on topic: Do you think it is reasonable to expect the display/touchscreen of two Allwinner based tablets sold by the same name (including model number) are identical, or do they use different displays / touchscreen elements all the time? greetings, jens -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
