Hey dude, this is the best SW for cellphone LCD's: LCDHype and this page has the wiring for older Ericssons: Ericsson A2618 I haven't seen anything for color phones yet but if you have an older Ericsson or Nokia this SW is fantastic !
i'm asking because i got a spare display and want to use it to something cool. just a datasheet will be a BIG help
From the LCD FAQ at the top: http://forums.bit-tech.net/showpost.php?p=457795&postcount=5 While you're not asking about a laptop LCD, the idea is the same. You need a controller and it's probably more of a hassle than you will be willing/able to go through. -special [k]
Ummm I don;t want to be a smart ass but phone LCD's all HAVE on board controllers. THat's why it's SO easy to interface them to the parallel port using this SW LCDHype Laptop LCD's are a COMPLETELY different story and not what this thread is about.
Not all Phone LCD's have on-board controllers (often times the LCD will be connected to the board via contacts and the controller will be on the phone circuit-board, although there are exceptions). Laptop LCD's are not COMPLETELY different and I never said that the thread was about them (*cough* "While you're not asking about a laptop LCD..." *cough*). Sooo... the software you linked supports: What is in the Erikson then? TTmodder hasn't quoted any part numbers (other than the phone's), so it's more difficult for people (especially people who don't have them) to figure out how to help. If he can give more information about the LCD/controller, maybe we could figure out how to help. I still stand behind my post that "it's probably more of a hassle than you will be willing/able to go through". -special [k]
OK, I couldn't be bothered typing out ALL the info I know about phone LCD's, suffice to say being a Mobile Phone Tech I have a certain familiarity. AFAIK there is no software that I know of that supports the Ericsson T230, however the color screen Nokia's have SW & HW that's being Beta tested here : Nokia 3510i here : LCDInfo here : apeTech.de here : Nokia 6100 display library and here : Berty's Phone Pinouts I imagine that if you don't know much about phones or how to solder at SMD level then this would be a hassle to hook up to a computer, but, having hooked up a Nokia 3310, 3210, 8210, 5110 & 6110 LCD to my own PC using the diagrams & SW from here : LCDHype I can honestly say it's not beyond most people... YMMV PS: This whole Modding Scene is about smart people with a bit of imagination doing things that other people consider too much "hassle" to do. If we weren't hacking HW to make it do our thing in our own way then we'd just be buying beige PC's like all the other pleb's out there....
i can make my own pcb for the controller and the display and solder it on so thats not the problem. only thing i need for is the controller's and the lcd's datasheets
OK here's how it goes: 1. THe controller for the T230 is already on the LCD NOT seperate like our ill informed friend thinks. 2. Nobody has yet done this hack to a T230 so you'll need to FIND out what the controller is (probably one of the Philips or Epson variety) 3. YOu then need to design your own interface between the parallel port and the LCd without blowing up either. 4. With all of the above done, you now need to write your own SW to access the LCD OR write a plugin for LCDHype that translates the SW into commands the LCD understands. 5. I've given you ALL the links and information you need to get started and any further Q's should be directed to the people who have designed the interfaces or the SW, Good Luck you'll need it !
As for laptop LCD/TFT, they do have onboard controllers, but those use a non standard digital interface with a high bandwith wich means you can't hook it to the paralell port (too low bandwith), so you need to make a translator to use DVI och VGA input. Phone displays with built in controllers, being a lot smaller with slower update times, can be connected to a serial or paralell port, and the translation made in software on the computer, since these displays do not use at all as much bandwith as the comparatively huge laptop displays. The problem is figuring out the interface since most manufacturers are restrictive about giving away design manuals to anyone who asks. Just don't ask me about any specifics, what i wrote above is just about all i know on the subject
I also have a t230 LCD..it doesnt have the same numbers on the white part of it(mine says 2673m04), but it seems to share the numbers "942 213 R1B" It would be really sweet if someone knew what sort of controller these LCD's used...is there anyway to find out?
the number at the side is maybe production number and the other one is the product type. i'll try search for 942 213 R1B
Not to disapoint, but that LCD has no controller. The stuff on the flex connector is just there to minimise the number of data lines between the LCD and the controller, which must therefore be integrated into the phone's main PCB. In other words, just chuck it.
Really? well, if that's the case then why wouldn't I (we) just interface to the controller on the phone's motherboard?
Hello!!! What append with this??? Did anybody got to interface de T230 LCD??? With or whithout controller, the connection of the LCD is only three signals plus two voltages. It would be posible to drive it directly, isn't it???
Here, you can see the connections of this LCD http://sandiding.tripod.com/lcdt230.html And the LCD connections is true, at least...
Can anyone find DataSheets for this thing though? If I had a datasheet I could likely write up a simple graphics library (or write a driver for serdisplib) My LCD module appears to be the same as berty's (above mentioned website) But the keywords I searched all give me LCD's which have many times the amount of pins on my module. Any help? EDIT: Oooohh, on further inspection, the UC1682 controller has a serial mode (which seems to be used here.) Any one interested should download "UC1682.pdf" by UltraChip and check it out - I'll see what I can do (I may have to brush up on parallel port interfacing)
