candle Posted August 30, 2012 Share Posted August 30, 2012 hello all seems that most obvious information is hardest to find what are psychical lcd screen dimensions? but not only active area (that is what makes that 160x102 pixels) but the whole module, including its thickness Quote Link to comment Share on other sites More sharing options...
GadgetUK Posted August 31, 2012 Share Posted August 31, 2012 Without taking my Lynx apart, Ive got no idea. Why not take yours apart to measure it? Are you talking about Lynx 1 or 2? Quote Link to comment Share on other sites More sharing options...
candle Posted August 31, 2012 Author Share Posted August 31, 2012 i don't have any lynx, in fact, i even haven't seen one in flesh in my entire life, yet i need that information badly Quote Link to comment Share on other sites More sharing options...
GadgetUK Posted August 31, 2012 Share Posted August 31, 2012 Why do you need to know then? Quote Link to comment Share on other sites More sharing options...
candle Posted August 31, 2012 Author Share Posted August 31, 2012 (edited) perhaps you should make a query over my posts, and learn what i do? just a hint Edited August 31, 2012 by candle Quote Link to comment Share on other sites More sharing options...
zoltan Posted September 2, 2012 Share Posted September 2, 2012 Hi candle, I dont know the dimensions of the Lynx screen either, BUT if you need this information because you are planning to make a proper lcd screen for the Lynx then I am happy to disassemble one of my Lynxes and measure the screen ( dreaming, dreaming... ).

Shawn Jefferson Posted September 2, 2012 Share Posted September 2, 2012 Candle will have a Lynx soon... if nothing untowards happens to it in transit. Candle's contributions to the Atari 8-bit scene: Ultimate 1MB upgrade, VBXE 2 upgrade, Simple Stereo board, Incognito board to make 800 into XL/XE, probably many more I'm forgetting. He's a hardware wizard with a proven track record of making reliable, quality, afforable upgrades. Definitely someone in whom you want to foster an interest in the Atari lynx.

candle Posted September 3, 2012 Author Share Posted September 3, 2012 all lies! but yes, i do want to have tv-out and proper lcd screen replacement as the one it has it's not up to today's standards Quote Link to comment Share on other sites More sharing options...
GadgetUK Posted September 3, 2012 Share Posted September 3, 2012 I think you've got quite a challenge in front of you!!! I only have Lynx 2's, i dont mind taking mine appart later if no one else has one in bits. I think the problems are going to be timing related, resolution differences, and colour mapping. I guess if a composite signal could be made (which I think will be very difficult with what the Lynx provides), then an aftermarket LCD will probably work if it fits (a bit like the NOMAD mod), plus youve got composite out as well then with no extra work. The other option is to try and drive an LCD directly with minimal electronics inbetween hopefully, but I am not sure how standard the Lynx LCD is compared to most modern LCD's Quote Link to comment Share on other sites More sharing options...
GadgetUK Posted September 3, 2012 Share Posted September 3, 2012 You might want to burn the Lynx Diagnostics onto an EPROM as well. Get one of those Pasui 256Kb PCBs - or make one, then you can use the colour / screen tests to aid investigation with a scope or other diagnostic tools etc. Quote Link to comment Share on other sites More sharing options...
+karri Posted September 3, 2012 Share Posted September 3, 2012 The visible part of the screen is 75mm wide and 48mm high. Quote Link to comment Share on other sites More sharing options...
matashen Posted September 3, 2012 Share Posted September 3, 2012 160x102pixel 3,5" Quote Link to comment Share on other sites More sharing options...
candle Posted September 3, 2012 Author Share Posted September 3, 2012 75x48 gives almost squre pixels, this is very good, because simple upscaling x2 can be used what is overall thickness of lcd module including the backlight? Quote Link to comment Share on other sites More sharing options...
+karri Posted September 5, 2012 Share Posted September 5, 2012 The thickness is 20mm. - Karri Quote Link to comment Share on other sites More sharing options...
+karri Posted September 5, 2012 Share Posted September 5, 2012 By the way... There is one special thing in driving the Lynx LCD. Usually the Lynx displays only 16 colors at the same time out of a palette of 4096 colors. The Lynx can actually drive 4 bits per color (12 bits total). Some Lynx programs take advantage of this and change the palette at the start of each scanline. Then you can have a different set of 16 colors for every scanline. In case you plan to use the actual LCD control lines then there is no problem with this. -- Karri Quote Link to comment Share on other sites More sharing options...
candle Posted September 5, 2012 Author Share Posted September 5, 2012 i do, but i found some demos using "high colour mode" which seems to be just plain old triple interlace - not very good on modern displays, they are not as slow as the one inside lynx, not by any chance 20mm is a brick-thick i though it would be 5 or 7 at most, making things tricky, but not impossible, with 20mm we're good, will have to think of some kind of supports... how about outside dimensions? so far we have thickness, and active area ps. modern 3.5" modules have active area of 70mm, leaving 2.5mm black stripes on each side - i'm targeting here in QVGA (320x240) display with square pixels, and upscaling incomming video stream by factor of 2 (160x102->320x204) - image will be proportional, and crisp clear, but slighty smaller though 2 Quote Link to comment Share on other sites More sharing options...
obschan Posted September 6, 2012 Share Posted September 6, 2012 On my lynx 1, -thickness 2 white plastic plates, 2x1mm the screen itself, 2mm gray plastic support, 5 mm It's a bit handmade but it can be a start... Quote Link to comment Share on other sites More sharing options...
108 Stars Posted September 6, 2012 Share Posted September 6, 2012 (edited) I wonder if maybe thanks to the thick original display there may be room when a new screen is put in to also replacethe backlight. I imagine that nowadays there are better and less energy consuming ways to light the screen. Similar mods for Game Gear and Nomad improved battery life quite a bit afaik.

candle Posted September 6, 2012 Author Share Posted September 6, 2012 (edited) obschan: how it connects with main board? 108 Stars: novadays LCD including LED backlight is 3.5mm thick Edited September 6, 2012 by candle Quote Link to comment Share on other sites More sharing options...
obschan Posted September 6, 2012 Share Posted September 6, 2012 I guess the white plates are there o diffuse the back-light from the other side of the board. obschan: how it connects with main board? On the second pic. you can see on the right a 'soft' connector, I believe the green one at the bottom is a connector too. Quote Link to comment Share on other sites More sharing options...
candle Posted September 6, 2012 Author Share Posted September 6, 2012 not much of a connector, just a flex ribbon, but it doesn't actually show the connector Quote Link to comment Share on other sites More sharing options...
obschan Posted September 6, 2012 Share Posted September 6, 2012 http://www.allthingsvolvo.zoomshare.com/ Can see it there on the "back of the screen disconnected" pic. Quote Link to comment Share on other sites More sharing options...

roland p Posted September 6, 2012 Share Posted September 6, 2012 I found some pictures of the lynx 1: http://www.mdgames.de/lynx_i_description.htm The backlight-tube and the ribbon seems to be connected directly to the pcb. Quote Link to comment Share on other sites More sharing options...
