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 LVDS
thiseducational 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 with
portrait 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 that
at 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.
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 appears
So), 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 in
thistheme. 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).Post has been editedBoris-leo - 21.01.18, 00:58
