Many of you have old or broken laptops that lie idle, but some parts in which it is currently working, so it is a pity to throw away the device. And if you suddenly wanted to make a second or third extra monitor for your computer, then this laptop would be just in time. Today I’ll show you how to do the work of the make a matrix of the laptop monitor, which can be universally used.
Author’s note: most of the photos taken from the network, because my unit at the time of writing this article has already been assembled and disassembled it did not want, but that does not prevent me to convey the essence of the assembly process.
The first thing we need is a working laptop matrix. At this point you have to be 100% sure that it actually works, otherwise, the following action is useless. So, my patient – HP Pavilion dv9000, in which one of the broken display fixtures and burned video module, but the matrix is 17 inches and resolution of 1440 × 900 working.
Carefully dismantle the make a matrix of the laptop and retrieve the display, and then the very matrix. For the majority of devices in the network have the detailed disassembly instructions. I also drew a speaker and webcam. As a result, we get approximately the following picture.
HOW TO MAKE A MATRIX OF THE LAPTOP A NEW MONITOR?
- jack for connecting the LVDS cable.
- connector, which connects to the backlight inverter.
Look carefully at the labels and find the model matrix. As you can see, the HP laptop I and the matrix of the SAMSUNG, we are interested in LTN170X2-L02 label, this is the model matrix. The fact that after the sign “-” can not be ignored in the search, is important to us only marking LTN170X2.
Then go on AliExpress or eBay , and trying to drive in search for the following query: LCD Controller Board LTN170X2.
We find us a suitable product photograph matrix with all the stickers and send the seller through the form of personal messages. In a letter to write about the following text (course in English): Hello, I have in there is such a matrix, the photo attached to the letter. It will run your card with my matrix. Thanks, If the seller responds positively, and the price you are comfortable with -. Make an order, if not – we are looking forward.
If you do not need any video input, you can easily find, for example, the fee to one of the inputs you are interested in. Thus, you can also reduce the cost of the device.
WHAT DO WE NEED TO MAKE A MATRIX OF THE LAPTOP A NEW MONITOR?
- Input for 12V power supply
- HDMI Input
- DVI Input
- VGA input
- Audio Input
- Audio output
INCLUDED ARE THE FOLLOWING (THEY MAY DIFFER SLIGHTLY IN APPEARANCE AND CONNECTION METHOD):
- LVDS cable that connects directly to the matrix monitor.
- The inverter is responsible for the work of illumination.
- Mainboard controller.
- Push-button interface to adjust the image settings.
- For connecting the push button interface cable.
- The cable for connecting the backlight inverter.
Connectivity problems should arise, to confuse the wires also will not work. When assembled, it looks like this:
Next, we should check whether all our device. Connect the LVDS cable to the socket in the matrix, the matrix also has a cable for lighting, we connect it to a free slot backlight inverter. We find in the bins or buy the power supply to 12V, may come up and away from your broken laptop. Be sure to look to plug easily connected to the control board socket. Then connect the computer’s video output to the video input control board one of the three cables (HDMI, DVI, VGA). We serve 12V, enabling our power supply into a power outlet. Up! Nothing happens. As in a conventional monitor device provides a power button \ off. Push the button «ON \ OFF» on the keypad interface. And lo! We see the image. If you are at this stage a black screen, verify that you have properly connected all the wires, whether they are well seated in the nests of boards, working there any way you have the power supply. I have everything turned out right the first time.
Then this whole bunch of wires and circuit boards should be beautifully mounted on the monitor. I screwed all the boards to the back of the plastic of the monitor, pre-drilled holes for two LVDS cable and backlight inverter cable since they are directly connected to the matrix. Also, to the rear, I fastened two metal brackets to put the monitor on the table without any problems. You can attach the mountings for the monitor on the wall, if necessary. Here’s what happened in the end, my brutal monitor.
WHERE AND HOW CAN :
The first two points are only applicable to video cards with multiple video outputs. How to make a matrix of the laptop a new monitor?
1) As an additional desktop. For example, you start the movie on one screen, while the second do surfing the web or typing text. And no need to open \ close, minimize \ deploy prevent window.
2) as a back monitor. You can take him to another room and watch, for example, a movie or your favorite show are already there. In my board has audio input and output, you can easily connect the speakers. Also, do not be a problem to find a long video, I have worked with a VGA cable, whose length is more than 20 meters.
3) If you are familiar with the Raspberry Pi, you will also be able to connect to it this monitor with no problems.
