tft display teardown quotation
We test the individual components for functionality and can locate defective components within very short time. We fix the component assemblies of LEDs and CCFLs, inverters, display controllers and PSUs. In many cases we also use new display controllers or inverters in order to ensure a longer life time of the monitor.
Display brightness gradually decreases or fails completely. We replace CCFL in displays from 8.4"" to 15"" within shortest time. For the future, we are also equipped for the LED backlight technology.
We stock special tubes such as W-, U- or L-shaped tubes. In this way, we are able to replace the backlight tubes for special displays such as the Sharp LQ150X1LGN2.
Polarization foils turn yellow over the years due to heat and other factors. Eventually, the displayed image becomes unclear or difficult to read. We replace polarization foils for sizes up to 15"".

The DT022BTFT uses the same connections as the DT022CTFT, with the exception of the backlight (which has connections shown in the Displaytech datasheet).
The provided display driver example code is designed to work with Microchip, however it is generic enough to work with other micro-controllers. The code includes display reset sequence, initialization and example PutPixel() function. Keep the default values for all registers in the ILI9341, unless changed by the example code provided.
Note that the WR pin becomes the D/CX signal in serial mode. CS is used to initiate a data transfer by pulling it low. At the end of the data transfer, pull the CS pin high to complete the transaction. The timing diagram indicates that you can pull the CS pin high in between the command byte and data bytes within a transfer, but it is unlikely needed if the display is the only device on the SPI bus. To keep things simple, we suggest to leave it low during the entire transaction.

Please see the DT028CTFT for reference designs. The schematics between the A and the C are the same with the exception that the A does not have the IPS interface.
VIS024TN01 is a 2.4″ TFT LCD display module model that adopts TN type LCD with 240*320 resolution. CTP (Capacity Touch Panel) or RTP(Resistive Touch Panel) can be added according to user requirements.
The 2.4-inch TFT-LCD is probably the most sold LCD panel size in the world in terms of unit shipments. It has a wide range of applications and life cycle.
Based on the substantial and long-term shipments of 2.4 inch TFT LCD panels, we can guarantee a stable supply of this LCD display module throughout the life cycle of your product.
Based on the 2.4 inch LCD’s high stability, low price, and excellent storage and operating temperature range, this type of LCD display module can be widely used in feature phones, smart homes, pos machines, industrial instruments (meters), and small medical equipment and other products.
One of best advantages of Flatscreen LCD displays is the small footprint they take up on a desk. With stands that need not be more than abut 6" deep the space saving is significant. In the case of the 570S TFT those space saving features can be extended even further. With the panel being no more than 2.5" thick, and thanks largely to a removable stand, this display can be hung on a wall or even paced in a drawer.

Click to expand...Many on here have had their display fixed, it is very common issue. The display may be available from Ferrari but they would be very expensive, I think it is in a prior thread. I do not believe Ferrari "certifies" anyone to repair the display. Repair does not interfere with the computer; your statement appears to be conjecture (not validated as the cause) on what caused a computer problem.
Click to expand...Not sure I follow your first lines. Are you saying the OP has a replaced screen because he/she calls it TFT and you say the original is LCD? TFT is a type of LCD screen.

599s were coming with the (regular LCD), and that"s the reason I guess Y lots of owners upgraded to TFT, cuz the regular ones has their problems with time.

But in the case of the car I mentioned, I believe the whole works has been changed not the display only. And some how it makes sense, cuz it might require different wiring or chips to install.
Click to expand...Think what you want. Your next response makes it clear how little you know about this issue or electronics. For the record, my degree is in electronics engineering so I know the difference. The point is THERE IS NOT AN LCD AND A TFT VERSION; There is only one version. People are getting them repaired and most of the time they replace the driver chip that burns out, they don"t change the panel. And changing the cluster does not require different wiring or different chips. It has to be programmed with an SD but it isn"t voodoo magic.

While we’re being pedantic, Thin Film Transistors are a subset of Liquid Crystal Displays. Rather TFT are most often used as part of an LCD. So the 599/612 does use an LCD display, which is also a TFT display.

Unless the programmable memory is corrupted, then coding or other programming of the cluster isn’t an issue for display repair. Those components either won’t be touched, or if they are then the contents can be downloaded and stored first for replication if needed.
Click to expand...This description sounds like the headlight system. They haven"t ever used an HID in the display panel. I don"t know if the 599 ever had anything but HID, I would think not. Technically it could be changed to LED but changing the light engine requires a redesign of the reflectors (if you want optimal performance from the). Xavier posted a picture of the driver chip that get replaced.

A thin-film-transistor liquid-crystal display (TFT LCD) is a variant of a liquid-crystal display that uses thin-film-transistor technologyactive matrix LCD, in contrast to passive matrix LCDs or simple, direct-driven (i.e. with segments directly connected to electronics outside the LCD) LCDs with a few segments.
In February 1957, John Wallmark of RCA filed a patent for a thin film MOSFET. Paul K. Weimer, also of RCA implemented Wallmark"s ideas and developed the thin-film transistor (TFT) in 1962, a type of MOSFET distinct from the standard bulk MOSFET. It was made with thin films of cadmium selenide and cadmium sulfide. The idea of a TFT-based liquid-crystal display (LCD) was conceived by Bernard Lechner of RCA Laboratories in 1968. In 1971, Lechner, F. J. Marlowe, E. O. Nester and J. Tults demonstrated a 2-by-18 matrix display driven by a hybrid circuit using the dynamic scattering mode of LCDs.T. Peter Brody, J. A. Asars and G. D. Dixon at Westinghouse Research Laboratories developed a CdSe (cadmium selenide) TFT, which they used to demonstrate the first CdSe thin-film-transistor liquid-crystal display (TFT LCD).active-matrix liquid-crystal display (AM LCD) using CdSe TFTs in 1974, and then Brody coined the term "active matrix" in 1975.high-resolution and high-quality electronic visual display devices use TFT-based active matrix displays.
The liquid crystal displays used in calculators and other devices with similarly simple displays have direct-driven image elements, and therefore a voltage can be easily applied across just one segment of these types of displays without interfering with the other segments. This would be impractical for a large display, because it would have a large number of (color) picture elements (pixels), and thus it would require millions of connections, both top and bottom for each one of the three colors (red, green and blue) of every pixel. To avoid this issue, the pixels are addressed in rows and columns, reducing the connection count from millions down to thousands. The column and row wires attach to transistor switches, one for each pixel. The one-way current passing characteristic of the transistor prevents the charge that is being applied to each pixel from being drained between refreshes to a display"s image. Each pixel is a small capacitor with a layer of insulating liquid crystal sandwiched between transparent conductive ITO layers.
The circuit layout process of a TFT-LCD is very similar to that of semiconductor products. However, rather than fabricating the transistors from silicon, that is formed into a crystalline silicon wafer, they are made from a thin film of amorphous silicon that is deposited on a glass panel. The silicon layer for TFT-LCDs is typically deposited using the PECVD process.
Polycrystalline silicon is sometimes used in displays requiring higher TFT performance. Examples include small high-resolution displays such as those found in projectors or viewfinders. Amorphous silicon-based TFTs are by far the most common, due to their lower production cost, whereas polycrystalline silicon TFTs are more costly and much more difficult to produce.
The twisted nematic display is one of the oldest and frequently cheapest kind of LCD display technologies available. TN displays benefit from fast pixel response times and less smearing than other LCD display technology, but suffer from poor color reproduction and limited viewing angles, especially in the vertical direction. Colors will shift, potentially to the point of completely inverting, when viewed at an angle that is not perpendicular to the display. Modern, high end consumer products have developed methods to overcome the technology"s shortcomings, such as RTC (Response Time Compensation / Overdrive) technologies. Modern TN displays can look significantly better than older TN displays from decades earlier, but overall TN has inferior viewing angles and poor color in comparison to other technology.
Most TN panels can represent colors using only six bits per RGB channel, or 18 bit in total, and are unable to display the 16.7 million color shades (24-bit truecolor) that are available using 24-bit color. Instead, these panels display interpolated 24-bit color using a dithering method that combines adjacent pixels to simulate the desired shade. They can also use a form of temporal dithering called Frame Rate Control (FRC), which cycles between different shades with each new frame to simulate an intermediate shade. Such 18 bit panels with dithering are sometimes advertised as having "16.2 million colors". These color simulation methods are noticeable to many people and highly bothersome to some.gamut (often referred to as a percentage of the NTSC 1953 color gamut) are also due to backlighting technology. It is not uncommon for older displays to range from 10% to 26% of the NTSC color gamut, whereas other kind of displays, utilizing more complicated CCFL or LED phosphor formulations or RGB LED backlights, may extend past 100% of the NTSC color gamut, a difference quite perceivable by the human eye.
In 2004, Hydis Technologies Co., Ltd licensed its AFFS patent to Japan"s Hitachi Displays. Hitachi is using AFFS to manufacture high end panels in their product line. In 2006, Hydis also licensed its AFFS to Sanyo Epson Imaging Devices Corporation.
A technology developed by Samsung is Super PLS, which bears similarities to IPS panels, has wider viewing angles, better image quality, increased brightness, and lower production costs. PLS technology debuted in the PC display market with the release of the Samsung S27A850 and S24A850 monitors in September 2011.
TFT dual-transistor pixel or cell technology is a reflective-display technology for use in very-low-power-consumption applications such as electronic shelf labels (ESL), digital watches, or metering. DTP involves adding a secondary transistor gate in the single TFT cell to maintain the display of a pixel during a period of 1s without loss of image or without degrading the TFT transistors over time. By slowing the refresh rate of the standard frequency from 60 Hz to 1 Hz, DTP claims to increase the power efficiency by multiple orders of magnitude.
Due to the very high cost of building TFT factories, there are few major OEM panel vendors for large display panels. The glass panel suppliers are as follows:
External consumer display devices like a TFT LCD feature one or more analog VGA, DVI, HDMI, or DisplayPort interface, with many featuring a selection of these interfaces. Inside external display devices there is a controller board that will convert the video signal using color mapping and image scaling usually employing the discrete cosine transform (DCT) in order to convert any video source like CVBS, VGA, DVI, HDMI, etc. into digital RGB at the native resolution of the display panel. In a laptop the graphics chip will directly produce a signal suitable for connection to the built-in TFT display. A control mechanism for the backlight is usually included on the same controller board.
The low level interface of STN, DSTN, or TFT display panels use either single ended TTL 5 V signal for older displays or TTL 3.3 V for slightly newer displays that transmits the pixel clock, horizontal sync, vertical sync, digital red, digital green, digital blue in parallel. Some models (for example the AT070TN92) also feature input/display enable, horizontal scan direction and vertical scan direction signals.
New and large (>15") TFT displays often use LVDS signaling that transmits the same contents as the parallel interface (Hsync, Vsync, RGB) but will put control and RGB bits into a number of serial transmission lines synchronized to a clock whose rate is equal to the pixel rate. LVDS transmits seven bits per clock per data line, with six bits being data and one bit used to signal if the other six bits need to be inverted in order to maintain DC balance. Low-cost TFT displays often have three data lines and therefore only directly support 18 bits per pixel. Upscale displays have four or five data lines to support 24 bits per pixel (truecolor) or 30 bits per pixel respectively. Panel manufacturers are slowly replacing LVDS with Internal DisplayPort and Embedded DisplayPort, which allow sixfold reduction of the number of differential pairs.
The bare display panel will only accept a digital video signal at the resolution determined by the panel pixel matrix designed at manufacture. Some screen panels will ignore the LSB bits of the color information to present a consistent interface (8 bit -> 6 bit/color x3).
With analogue signals like VGA, the display controller also needs to perform a high speed analog to digital conversion. With digital input signals like DVI or HDMI some simple reordering of the bits is needed before feeding it to the rescaler if the input resolution doesn"t match the display panel resolution.
