Long I wanted vtulit board with the tablet in an old LCD monitor 19 ". Make yourself a Smart TV or something like a computer.
At Monica has three input 2 VGA and 1 DVI. But no HDMI. There are 2 speakers.
For these purposes, it has been bought for a penny : Tablet Pipo S1s (in the fully out, broken touch matrix + idle lights thereof) to be the working board and exit HDMI.
It took it as data aparata basically satisfied (1GB RAM, 2 cores at 1.6GHz), and take several years.
The board is connected to the VGA via HDMI-VGA adapter, which was in turn bought by Ali for about three ceto $.
At first thought to shove the whole thing in the body of the monitor, but a little pokumekat decided that I will incorporate a fee in the "paw" monitor.
Pitalova connector soldered stupidly instead of the battery.
Everything works and nothing is not heated, but it might be worth a little lower voltage power supply of the native, which later is integrated as well in the "paw" (space available).
sound button and turn led to the upper panel "paws".
By YUSB connected a 4-port hub to which are connected a wireless mouse, Claudia and flash card if necessary or something.
Fixing elements on the hot melt adhesive + screws (where worked.)
The buttons on the panel are connected by thin wires cutting a 80 pin IDE - loop.
Cover radiator board is contacted through thermal pads with metal lid itself "paws". Extras. plus cooling))

While not much akuratno, but it is fixable.
Next task is to get rid of all the wire nozzle.
To build a hub in Monique or paw, hide inside the monitor adapter.
Hide the power supply in the leg and connected to the power 220 Monica, or try to take 4 volts directly from the monitor.

Rep: (504)
What is there to expect? I say so be it. The monitors are powered 5B maynborda, and a second voltage (12 ... 14 or 19 ... 22B) of the inverter is powered.
For the purposes take 5V. Firstly it is more "pure" than 12V, and secondly take it and supplied to the hub. On the tablet power - his own, but after a couple of high-power diode (battery generally throw out). Diodes must withstand current 3A order. Less is not necessary - will be heated. The terminals of the tablet supply (I'm talking about the board itself) solder Conder 2200 uF 6.3 ... 10 V and supply power directly through the diodes in the same terms. Otherwise, without Conder tablet it will light up, and then begin to fall the percentage of "charge" and eventually fall to disconnect the tablet. The hub will have cut the track power to share power hub and USB OTG connector plate. That's when it will be possible to a USB hub to hang anything you want - then it all drags. It has long passed all stages.

If you suddenly begin to choke the monitor PD (still eats tablet and a half amperes) te.monitor will cycle off or do not run, then there will be only one way - to use a switching regulator typesuch aand it powered by a voltage inverter. To expose its output 5V and manipulate them. Stabilizer KREN5 (7805) can not be used, only a pulse.
These converters are sold not only in China, but also in our Radio Shack (more expensive of course, but there).

all plates with OTG and a broken display and touchscreen and no HDMI, you can try to connect to the matrix monitor or laptop without any lotions directly .If provided that the tablet has a display controller.


I would like to learn more in detail. There zopo c2 (2 pcs.), One will go to the connectors, the second is alive, but the touch is cracked and half does not work. How do I connect it to the screen?

I know the truth. The correct answer - do not connect. Experience needed.
read the educational programhere.
Well? It remains only to verify for each line whether the iron plate drags calculated to hiluyu matrix with a resolution of a monitor voracious matrix with different resolution and foreign (in terms of tablet) illumination.
Immediately drew attention to the concept of "permission". It is characteristic of iron, giblets tablet "sharpened" ONLY applied under the matrix and the matrix when connected with another resolution nothing good happens. These guts CAN NOT choose the resolution - it's not a laptop with his card. On the other hand the resolution - iron characteristic matrix. Her entire electronics will work correctly only on its own (that's right - "native") resolution.

So if someone tells you that you can slip the tablet into the monitor, then, as would say one hero of Mimino: "Here's the brush, here - itself selected paint color, he kras ...."

No, well, you can try aypad 1 cram into a square a "tag." If it is necessary - I'll tell you how ... But it is necessary game worth the candle?
More unfortunately, nowhere and nothing to shove will not work.

There is a high probability to attach the matrix notebooks from 15.4 "(1280 * 800) to the tripe of a tablet with the same resolution, interface and bit depth. Just have to take additional measures to feed the matrix and the organization of its lighting and manufacturing or purchasing transient loops. In other porukodelnichat words. But for this you need a good radio engineering training.

The original text is moved to a more extensive and more appropriate topic.

Rep: (504)
If there are living entrails of the plate, they can be used, but with one caveat: If the board has an HDMI output, as they say, the doors open out into the world, and if on tripe no HDMI, it is likely that it is only suitable to donor. I will dwell on this a little bit more, because many console themselves with the hope (or are guided by rumors), that has a way of supposedly "get" from the bowels of the tablet (or smartphone) signals to the matrix and prizhivit their discretion. Answer: No such technical capabilities, 100% !!! Probably I will describe the causes of postulates - so it will be clearer:
1. None of the data output protocol (LVDS, TTL, or MIPI) disassembled into edrene and folded so as to obtain the HDMI (or DVI), is virtually impossible. China's one converter LVDS-HDMI, seen in the vast but its value is quite high and, moreover, do not know the answer to the question: what kind of LVDS have to give him to the entrance to get HDMI. For details and inquiries by type of LVDSthiseducational program. Why we are talking about getting HDMI - because both LVDS and HDMI (DVI) - is an interface for transmitting digital data. Stream obtained from the digital analog (same VGA) signal directly impossible even in theory.
2. If the tablet WAS matrix with MIPI interface, the method to convert from MIPI though in something - does not exist.
3. If there was a matrix tablet withportrait resolution (even with LVDS), the way to rotate the image 90 degrees hardvarnogo not yet invented. Therefore, even in theory, to obtain for the subsequent conversion of such data is meaningless.
4. With regard to smartphones, we can provide a triple guarantee that no HDMI output from its iron just did not work:
- ALWAYS matrix portrait
- in good smartphones matrix always MIPI interface
- the matrix is ​​often non-standard resolution.

However, quite often it happens that is out of business from the tablet matrix. And sometimes a very civilized. How to attach it - about this and will be discussed in this part.
So, let's begin.
Objective: To connect the matrix of the tablet (e-books, photo frames.) To a computer (extender, digital tuner, analog video cameras) Interface VGA (DVI, HDMI, AV). The phrase seems to be simple, but it is hidden everything that can be counted. How to connect the notebooks and TV (diagonal 26 ... 55 inches) of the matrix - this question, I probably will not raise, as this subject is beyond the scope of the forum.
How it works: the matrix "zapokazyvala", it must be connected to an electronic unit which is referred to as a display controller.
That is, the controller general. This separate unit, which has a set of inputs that the main controller chip converts the corresponding interface matrix. Operation of the controller chip controls the firmware, which is sewn into the non-volatile memory (SPI Flash). It is not difficult to guess that the firmware - is flashing, which contains data on all modes of operation of the controller, and it is supported by the resolution of the matrix, the EDID and the whole algorithm of the controller as a whole. Operational menu settings are stored either in the same memory chip, or in a separate eeprom. And besides controller provides management and operation of illumination matrix. It is a question not of any controllers that of commercially available units, but the controllers manufactured specifically for DIY.
To begin, I will tell you how to connect the matrix of the budget tablet, and then touch on a few matrices from expensive models, which are used not fake Chinese fakes on the Chinese Matrix and the real brand. For reference: the real brand manufacturers matrices for many is unknown, but they include Hannstar, Innolux, ChiMei, AUO (or AU Optronics), CPT (or Chungwa), LG-Philips, Samsung, BOE, Hydis and their joint cabal. Noneymy produced in other factories of China. Perhaps even over the fence from the eminent manufacturer. Additional cost matrices exists from 10 to 50 clones (namely noneymov) known branded products. Interesting fact: some noneymy has become a very popular brand and it is connected with the economic situation in this market, as there is a merger, purchase of plants, budding, etc.
Before taking any steps, the first step is to find out whether your matrix for such crafts. Of the whole business falls EXPRESSLY following matrix:
- every single IPS matrix with MIPI interface. The fact is thatat this interface the controller has not yet been invented in the world. One comrade (luckylamer) long laugh at this phrase and sent to Google search. I might put it clumsily - they are, but buy the cheaper version with Aliekspress for 12000-16000 rubles (Russian, not Belarusian) for the revival of the matrix of a broken tablet is unlikely that anyone will be solved. Therefore, laugh more ... These are all of the matrix with a diagonal of 7.85 ", the vast majority of widescreen matrixes 8" and some part with diagonals of 9.7 and 10.4. "To find out which interface in your matrix, enough to go on panelook.com, to drive her name in the search tab and look in the Specs section Signal Interface is not the name of the tablet and the matrix name -. it is written on its nameplate overwhelmingly MIPI connector is very small, double-row with the number of pins 36..
- matrix of aypadov 3 and 4 (resolution 2048 * 1536). The idea of ​​attaching them far go beyond "budget options" and besides, except eDP other inputs that option does not involve.
- matrix "portrait" resolution. Portrait orientation - it zhelezyachnye matrix property. I will explain the example. For comparison matrix take on Texet TM-7043XD (N070ICG-LD4 1280 * 800) and from Nexus 7 (CLAA070WP03XG 800 * 1280) and compare. In the first horizontal line consists of 1280 pixels, and the entire frame is composed of 800 lines. The second horizontal line consists of 800 pixels, and the frame is composed of 1280 rows. That says it all - the other one can not be replaced under any circumstances. And as all wondered controllers to monitor, and to fit the landscape frame in portrait without significant geometric errors is simply unrealistic, and the firmware under the portrait mode natural nobody writes - their implementation is very complex and is not claimed. There is another way to distinguish matrix with portrait and landscape resolution quite simple: the landscape matrices trail goes from the inside of the long side (of the "width" of the matrix), while the portrait - from a short (of the "height") by orienting its "landscape ".
Hopefully, with this point clear.
Now that is suitable for the realization of the idea, and without any financial cost. This is - a huge seed matrices (usually noneymov) type TFT-TN from budget tablet with a resolution of 800 * 480, 800 * 600, 1024 * 600 and 1024 * 768. The lion's share of them constitute a matrix with diagonal widescreen 7 "(800 * 480 1024 * 600), and a large part of the" square "is represented by 8 matrices." All these matrices are only two kinds of interfaces - TTL and LVDS. To distinguish one from the other interface can even look at the matrix loop. Plume appears as a "soft" board in brown, yellow and orange tones with the contact pads on the edge. Incidentally, this loop is an edge connector with pins and has a name - FFC (or FPC), a distance between tracks is standardized (0.5 mm) and number for the majority of such matrices - 40, 50 or 60 contacts. The people they are called "pins" (from the English pin - contact). Matrices with pins 50 and 60 - a matrix TTL, and with pins 40 - LVDS. They differ by location and conductors - have TTL matrix conductors located on the connector all the same type and width, while LVDS matrices clearly expressed themselves LVDS line, surrounded by the "weight". Here are some examples of appearance.
Attached ImageAttached Image

Now what they are:
- the TTL 60-pin 7 "- 800 x 480, 16: 9
- TTL pin 7 50 "- 800 * 480 1024 * 600 16: 9
- the TTL 50-pin 8 "- 800 x 600, 4: 3
- TTL pin 8 60 "- 800 * 600, 4: 3
- LDVS 40 pin 7 "- 1024 * 600, 17:10
- LDVS 40 pin 8 "- 1024 * 768 resolution, 4: 3
Why I said above, it is easy to connect them. To do this, I'll make one more digression. All of the above matrix used in cheap tablets tend noneymy. However, they have famous ancestors. For 7 "800 * 480 original are matrices from Innolux types AT070TN92 (AT070TN94), 8" 800 * 600 - AT080TN52, for 7 "LVDS 1024 * 600 - EJ070NA-01 (HJ070NA-13) and 8" LVDS 1024 * 768 - EJ080NA-04. So for these innolyuksovskih matrices produced in one eastern country a huge number of controllers. And to find under his noneymovskuyu matrix controller, enough pre according to what I said reconnoitre its matrix, verify the accuracy of reconnaissance on the name plate in the same Yandex-market, and then to search for example on the same Aliekspress drive name brand matrix and look at the result.
The only thing I did not mention - originals for matrices TTL 7 "1024 * 600 50pin The strange thing is - they do not have the originals, they are in themselves, but their names are also not secret. 7300101463 E231752 NETRON-DY 94V-0 \ 1351, KR070PC9S. , KR070PK9S, CPT-7D-103-CPT7D37DB, FPC-T70P18V2, 773TG700E000011, 20000938-00, ERTP-07003, TG700E00, xc070xy, WY070ML521CP21A, 73002017512E E231732, 7300101462 E242868, SL007DC21B44, FJF70007AA, SL007DC18B05, YH070IF50H-A, SL007DC24B52, HN070ML304 -18, 700CPTNT-50Z-HD-V1, SH-07 046-B1, YGZ-JCMT070H131D21YC, FPC7005013-A, 7300130906, FPC70054, HH070D-18EL. And to find such a matrix controller, you need to drive to find that the "known" . from this list oddly enough, the most "famous" names it - 7300101463 E231752, 73002017512E E231732, E242868 7300101462 and YH070IF50H-A.
For matrices original TTL pin 60 is HSD070IDW1. However, hook them up a little more complicated. The fact that they have a TTL interface with the so-called gamma correction. If you look - they have the same resolution as the 50-pin TTL matrix, and the "extra" 10 contacts in the long run and have pins gamma correction. So to provide this correction, and connect in the same way as the 50-pin TTL matrix (FFC connector to 50-pin), there are adapters. There are only two species (one of the options it appearsSo), But unfortunately I had never met Ali, and bought only on Taobao.
For example vobem most widespread matrix Aliekspress search string - AT070TN92 (! I will not try, I seek for you!). We look at the picture and looking at them carefully. There's a sale there and do the matrix, and an overabundance of controllers to suit every taste. So consider the look of sets with controllers that there enters as connected.
For more information about the controller is inthistheme. In the same profile and can ask questions.

Some of the information has been changed due to the opening of the new themes (mentioned above).

Rep: (504)
The pin 26 pin is not a secret. Here she is:

This pinout is valid for all 26-pin matrices, but they have the problem of a different kind. The fact that the original brand was just nothing - one or two did Hannstar (HSD090ICW1), Chungwa (CLAA090JB02CW), Innolux (AT070TN07) and AUO (A070FW03). And the rest noneymov probably as much as the Chinese producers themselves TVs. And here there is a small ambush. Example 7 "matrix (from a TV !!!) in its total weight are 480 * 234, but managed to produce Chinese and 472 * 234 and 480 * 220. A 9" matrix is ​​480 * 272, 480 * 234, 640 * 220, 640 * 234 ... In short, the trouble ...
A selection of DIY controllers for these matrices is just not great - mostly on controllers from MStar MST702LF, MST703LF and even some that do not now remember. Here is the most widespread set to attach a matrix:

I turned to the Chinese, who have bought, I ask for the firmware. and they said that this thing is very old, and they are not trade more. Well, and threw the whole thing.
If you are interested in such a controller, thenherehe. As you can see, the price tag is not very happy.
If you need more information - download the datasheets. Names I gave matrices.
Even from the point of view thatherefor example a tablet controller for any matrix. But, sorry, it already and authorization and a lot of inputs, including HDMI. And at last only two bass AV input.
...Feel the difference...

Yes, and more. The matrix of the tablet and the matrix of the TV is not related. Apply one instead of another does not work. Therefore, for them and controllers are quite different.
