I have got this display and I don't know whether there is backlight installed or prepared. I know that you have a backlight in the TLX which can be used by installing a inverter at two solder tacks, but at my TLC the solder tracks have no connections to the rest of the LCD. I haven't found informations about TLC in the net. To cut a long story short, I want to know whether there is a shining foil installed or not. Please help me, thanks. There might be some mistakes inside, please don't worry, I have not finished learning English jet. |

if your lcd don't have backlight actually, then it's a reflective lcd, the chances you can put a backlight on it are very few: first you will "never" find a backlight that will fit. second: you will have to get ride of the reflective sheet on the backside of the lcd. |

So something like this  is not useful and I must get along with no light... 
The Website I found the pic and informations about it: http://www1.conrad.de/scripts/wgate/zcop_b2c/~flN0YXRlPTEwMTM4MTE4MDM=?~template=PCAT_AREA_S_BROWSE&glb_user_js=Y&shop=B2C&p_init_ipc=X&~cookies=1 |

Atleast the E0 in the TLX means there's an EL backlight. Without the E0 there's no backlight, so i do believe you do have it. How did you check that there's no connection to anything? |

Can you take a photo of the display ? I have never seen TLC-711A but I have both TLX-711A and TLX-711A-E0 so it might be possible to see if you have the EL sheet from the picture. |

I made some pictures with a camera, but they are not best. 1st you see my Display before my monitor: 
Then you see it from behind: 
The third picture shows it not in a housing: 
This shows it from the top: 
And last but really not least the connections for the light who are not connected to the LCD: 
There are no conductive strips on the other side from the solder tack to the rest. |

Well i mine's exactly the same and if you look at the pictures at the TC6963c page in here, you'll notice it's the same kind of thing there. Like in those pictures i also have a sticker which says TLX-711A H8H, but if you look under the sticker it says TLC-711A-E0. This is supposed to have a EL-backlight, but i haven't got around to do anything to the display yet, cause my other hardware and software isn't ready and i don't have a chip to make the 110v AC for the backlight yet. |

110 Volt isn't the problem, I've bought an inverter for 110V at Reichelt (http://www.reichelt.de). Perhaps you can't see the conductive strips from the pins for 110Volt, they are connected to other pins, but not to the display: This is what I want to show you in the last picture: |''''''''''''''''''''| ° °''''''''''''0 0 ???____110V |

they are in an inner layer of the PCB |

I meant that, if there's a backlight, which there should be, cause i have the same module and i'm supposed to have a backlight, then the 2 smaller points are connected to a inner layer of the PCB and from there connect to the EL-backlight. I can't remember the english word for the term. |

Well looking at the pictures on the net it seems that i do not have a backlight., bollocks, so neither do you, so just ignore my thoughts about the inner layer connections of the PCB. |

damn, i left this out: so in conclusion your module is plain TLC-711A-E0 = TLX-711A |
