Re: [ql-users] small LCD screen
And what would Nasta say about this? I could buy a kit and send it to him to look at it. A remark for Bill: imho this 640x480 LCD does not have a lot in common with the super LCD/plasma etc.. screens sold as TV sets nowadays: The design is very old, there are different technologies, and the price... But in the QL world 640x480 + 16 shades of grey, it is still usable. Arnould Jeremy Taffel a écrit: I saved the image. On analysis, the image is only 287x197 pixels, including the white background, . The picture itself is therefore only about 200x140. The screen actually gives 640x480. So the spatial resolution as shown is about 3 times worse than the real thing. However, before you get too excited, the image was 8 bit, and all 256 shades of grey were used. The device seems to be specified as only having 16 shades - if I interpret the 15:1 contrast ratio correctly. Reducing the image to 16 shades of grey degrades it significantly. I tried it, and it does not look nearly as good. So, the answer seems to be that the nixon+presley picture shown is not what the device gives. It gives more pixels, but fewer grey levels.

Maybe there is a small opportunity here. At the company I work for, we do a lot of automation. This means that some things need to be registered at different places/times during the production cycle (in this case in the food industry). We currently use either a PC for this (very big, allows way too much for what we need it for and it is not that cheap (sceens are a pain). In other cases we use a Bizerba ITU, which is a weighing terminal which can be controlled serially (very nice, but also very expensive). In the ideal case, we just need a simple remote screen (black and white will do, we need to be able to display one line of buttons, two lines of small text and one line of big text (or buttons and five lines of small text). If we can display more, that is better, but this is a minimum. We also need to have a remove keyboard. What could be done is build a small device which has a screen and keyboard and which can be controlled remotely either through the network (UDP) or using a serial connection. I have looked in the market for his kind of device and could only find something with a 2x40 display. I believe there is a market for this if the price is wright (less than 500euro). Maybe this is something Tony and/or Nasta can build? We could base this on a very simple QL and do the programming in SBasic. There is already a screen and keyboard connection, so that would be possible. It would onnly need a limited amount of memory (I think 128kB usable would be enough). A simple flash card could be used as persistent device (also allows distributing and cpoying software). In fact, this would be something which is way too powerful the use I have for it, but I am sure others would do more interesting things as well. What do you think? Joachim

What do you think? Joachim The QL was developped for the mass market. Maybe there could be an opportunity there again. Not without investments of course. Arnould

I will have to find the company (Can't remember now) as all the info was in my favorites before I formatted the hdd -and of course never backed that up! :-) that I bought it from and send the link to you. I can tell you right now though that it was an end of life product so it's unlikely that it is available and that's why the price was so low as I had to contact Sharp for schematics and they told me that they cannot send me any as it wasn't in production anymore (I found the schematics for my friend on the web in the end but that's another story) Phoebus -- Visit the QL-FAQ at: http://www.dokos-gr.net/ql/faq/ (Still uploading stuff!)

[ql-users] small LCD screen
Hello, This small LCD screen http://www.earthlcd.com/SK1001.HTM can be bought in quantities of several thousand at 20 USD. AFAIU this is an interesting price. However I am amazed by the quality of the display of Nixon+Presley in the example given. Can anyone confirm that it is possible to display such crisp images with such a LCD? Arnould
