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.

The transmittance of a pixel of an LCD panel typically does not change linearly with the applied voltage,sRGB standard for computer monitors requires a specific nonlinear dependence of the amount of emitted light as a function of the RGB value.

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.

Less expensive PVA panels often use dithering and FRC, whereas super-PVA (S-PVA) panels all use at least 8 bits per color component and do not use color simulation methods.BRAVIA LCD TVs offer 10-bit and xvYCC color support, for example, the Bravia X4500 series. S-PVA also offers fast response times using modern RTC technologies.

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.

The graphic display coordinates and the text display coordinates of the 2.2”screen are two different coordinates systems. The origin of the graphic display coordinates begin from the centre point of the screen while that of the later one begins from the top left hand side of the screen.

The following codes are just one part of the API funciotn description. For more information, please refer to ST7687S Library Introduction and Display Library Introduction.

* @The formal parameter size refers to the text size based on the font(6×8). Size is rounded to the integer greater than 0; if size is 1, the pixel points the font occupied will be 6×8. if it is 2, that will be 12×16. The text out of the screen cannot be displayed;

The function of the program: taking the centre point of the 2.2”screen as the starting point(note: the graphic display coordinates and the text display coordinates are two different coordinates, the centre point of the graphic display coordinates is (64, 64) while that of the later one is (0, 0)), display a character string ”fire” with red text background box, white font and the size of the font 2 on the screen. The formal parameter size of the function to set font size tft.setTextSize (uint8_t size) should be greater than 0 and the text out of the screen cannot be displayed.

The function of the program: use the software image2lcd.exe to extract the bitmap of one image and display it on the centre part of the 2.2”screen(note: for the reason of UNO’s internal memory, the following demo cannot be accepted on UNO since the image file is too large, but it can be displayed on ESP32. So you’d better choose small image file if you want to display it on UNO. ) The parameter selection of the software is provided below.

As a 2inch IPS display module with a resolution of 240 * 320, it uses an SPI interface for communication. The LCD has an internal controller with basic functions, which can be used to draw points, lines, circles, and rectangles, and display English, Chinese as well as pictures.

The 2inch LCD uses the PH2.0 8PIN interface, which can be connected to the Raspberry Pi according to the above table: (Please connect according to the pin definition table. The color of the wiring in the picture is for reference only, and the actual color shall prevail.)

The LCD supports 12-bit, 16-bit, and 18-bit input color formats per pixel, namely RGB444, RGB565, and RGB666 three color formats, this demo uses RGB565 color format, which is also a commonly used RGB format.

For most LCD controllers, the communication mode of the controller can be configured, usually with an 8080 parallel interface, three-wire SPI, four-wire SPI, and other communication methods. This LCD uses a four-wire SPI communication interface, which can greatly save the GPIO port, and the communication speed will be faster.

Note: Different from the traditional SPI protocol, the data line from the slave to the master is hidden since the device only has display requirement.

Framebuffer uses a video output device to drive a video display device from a memory buffer containing complete frame data. Simply put, a memory area is used to store the display content, and the display content can be changed by changing the data in the memory.

If you need to draw pictures, or display Chinese and English characters, we provide some basic functions here about some graphics processing in the directory RaspberryPi\c\lib\GUI\GUI_Paint.c(.h).

Set points of the display position and color in the buffer: here is the core GUI function, processing points display position and color in the buffer.

The fill color of a certain window in the image buffer: the image buffer part of the window filled with a certain color, usually used to fresh the screen into blank, often used for time display, fresh the last second of the screen.

Display time: in the image buffer,use (Xstart Ystart) as the left vertex, display time,you can choose Ascii visual character font, font foreground color, font background color.;

2. The module_init() function is automatically called in the INIT () initializer on the LCD, but the module_exit() function needs to be called by itself

Python has an image library PIL official library link, it do not need to write code from the logical layer like C, can directly call to the image library for image processing. The following will take 1.54inch LCD as an example, we provide a brief description for the demo.

Note: Each character library contains different characters; If some characters cannot be displayed, it is recommended that you can refer to the encoding set ro used.

The demo is developed based on the HAL library. Download the demo, find the STM32 program file directory, and open the LCD_demo.uvprojx in the STM32\STM32F103RBT6\MDK-ARM directory to check the program.

For the screen, if you need to draw pictures, display Chinese and English characters, display pictures, etc., you can use the upper application to do, and we provide some basic functions here about some graphics processing in the directory STM32\STM32F103RB\User\GUI_DEV\GUI_Paint.c(.h)

Image buffer part of the window filling color: the image buffer part of the window filled with a certain color, generally as a window whitewashing function, often used for time display, whitewashing on a second

Display time: in the image buffer,use (Xstart Ystart) as the left vertex, display time,you can choose Ascii visual character font, font foreground color, font background color.

image.cpp(.h): is the image data, which can convert any BMP image into a 16-bit true color image array through Img2Lcd (downloadable in the development data).

For the screen, if you need to draw pictures, display Chinese and English characters, display pictures, etc., you can use the upper application to do, and we provide some basic functions here about some graphics processing in the directory GUI_Paint.c(.h)

Display time: in the image buffer,use (Xstart Ystart) as the left vertex, display time,you can choose Ascii visual character font, font foreground color, font background color.

Copying the calibration values may slightly hard due to the small size of the LCD shield. If so, try saving the results as a file and copying the values via SSH or with something big screen.

There are two cable options for connecting the PanelDue, both options are included with the PanelDue V3 kit. Option 1 is the included 4-wire cable with Molex KK connector ends. Option 2 is the included 10-wire ribbon cable. For some boards, both cables need to be plugged in to enable both TFT panel and SD card socket.

The length of the 4-way cable is not critical, however the resistance per conductor should not exceed 0.1 ohm. The SD card socket on the TFT panel will not be functional. The cables supplied by Escher3D and Duet3D are about 800mm long. There have been reports of cables up to 1500mm long being successfully used. Take care to route the cable away from motor and endstop cables. Twisting the cables may help prevent cross talk interference.

Older versions of the Duet 2 WiFi/Ethernet need both the 4-wire and ribbon cable to be plugged in to use the TFT Panel and the SD card socket, when connecting PanelDue v2.0 or v3.0.

PanelDue will display the bed heater H0 first (even if it is disabled), then iterate the defined tools. It then iterates the defined heaters below this. It expects a 1:1 relationship between tools and heaters. This means:if you have a machine that uses one heater for more than one tool (eg a 2-into-1, filament-swapping hot end), it will display more tools than heaters. Tools may not line up with their respective heaters.

Due to constraints on display resolution, PanelDue can only display 7 heaters in total on 5" and 7" panels, and 5 on 4.3" panels. If there are more heaters and/or tools than this, some columns will overlap.

You can use the external SD card socket on the LCD panel if you have used a ribbon cable as described above. Please note, the SPI interface provided by this SD card socket is much slower than the on-board SD card socket built into the Duet. Therefore we recommend that you do not upload files to this card over the network. Use the external SD card socket only if you want to write files to the SD card on a PC and then move the SD card to your printer.

There are two types of controller chip commonly used in these controllers: ST7920 and ST7567. Some Duets support one or both of these types - see below for details. Both types use a menu system stored on the SD card, see 12864 display menu system.

These displays are typically clones of the RepRapDiscount Full Graphic Smart Controller and look like this. The better ones include a contrast adjustment potentiometer. Unfortunately some manufacturers of other displays using the same controller chip reverse the pinouts on the two ribbon cable connectors. The ST7920 controller chip is invariably powered from 5V, which means that the display need 5V input signal levels.

An example of this is the Fysetc Mini 12864 Panel. The controller chip is run from 3.3V, so these displays normally include level shifters which tolerate a wide range of input voltages.

The contrast setting for these displays is done in software. the M918 command supports a C parameter for this purpose. It is also necessary to set a resistor ratio parameter in software, which can be done using the M918 R parameter.

Duet 3 Mini provides two 2x5 ribbon cable headers for connecting a Fysetc 12864 Mini Panel version 1.2 or 2.1 (not 2.0) or compatible ST7567-based controller. When using a version 2.1 controller, the colours of the three Neopixel LEDs built into the display can be set using the M150 command with LED type parameter X2.

We do not recommend connecting a 12864 display with ST7920 controller to the Duet 3 Mini because the 3.3V signals provided by the Duet 3 Mini do not meet the specifications of the ST7920 controller chip when it is powered from 5V. If you do wish to try it, you will most likely have to reduce the clock frequency (M918 F parameter) to get it working at all, and it may not work reliably. Also, note that when configured for 12864 display with ST7920 controller, RRF provides the CS signal on the pin normally uses for A0 because that more closely matched the pinout of typical 12864/ST7920 displays.

The Duet 2 Maestro provides two 2x5 ribbon cable headers for a 12864 display using ST7920 controller. The connector pinout is compatible with the original RepRapDiscount design. There is also more information in this thread: https://forum.duet3d.com/topic/7609/conf....

RepRapFirmware 3.2 and later also support displays using the ST7567 controller. For these displays, use the standard cable EXCEPT the following two wires need to be connected to the EXPANSION header pins:

RepRapFirmware 3.2 and later support a 12864 display using ST7567 controller. RepRapFirmware 3.3 added support for a short string of Neopixels on Duet WiFi and Ethernet, so boards that use a Neopixel for the backlight should be able to be controlled. See this thread on the forum for more details.

We do not recommend connecting a 12864 display with ST7920 controller because the 3.3V signals provided by the Duet 2 WiFi/Ethernet do not meet the specifications of the ST7920 controller chip when it is powered from 5V. If you do wish to try it, you will most likely have to reduce the clock frequency (M918 F parameter) to get it working at all, and it may not work reliably.

The most recent version of the standard bigtreetech TFT firmware has built in support for RepRapFirmware. The pre-built images have this enabled by default.

Use the pins +5V, GND, IO_0_OUT and IO_0_IN on the IO_0 header (Duet 3), or +5V, GND, TX and RX on the PanelDue header (Duet 2). These should be connected to +5V, GND, TX and RX on the TFT, making sure that TX and RX are swapped.

Display technology plays a critical role in how information is conveyed. Since its commercialization in 1922 up until the late 20th century, Cathode Ray Tube (CRT) has dominated the display industry. However, new trends such as the desire for mobile electronics have increased demand for displays that rival and surpass CRTs in areas such as picture quality, size, and power consumption. One such technology that has replaced the CRTs is Liquid Crystal Display (LCD) due to their lightweight, low operating power, and compact design. LCDs allowed devices such as digital watches, cell phones, laptops, and any small screened electronics to be possible. Although LCDs were initially created for handheld and portable devices, they have expanded into areas previously monopolized by CRTs such as computer monitors and televisions. Other contenders for leadership in display technology are Organic light emitting diode(OLED) and Plasma Display.

LCD is an electronically-modulated optical device made up of any number of pixels filled with liquid crystals and arrayed in front of a light source (backlight) or reflector to produce images in color or monochrome.

An active matrix liquid crystal display (AMLCD) is a type of flat panel display, currently the overwhelming choice of notebook computer manufacturers, due to low weight, very good image quality, wide color gamut and response time.

The most common example of an active matrix display contains, besides the polarizing sheets and cells of liquid crystal, a matrix of Thin film transistor(TFT) to make a TFT-LCD. These devices store the electrical state of each pixel on the display while all the other pixels are being updated. This method provides a much brighter, sharper display than a passive matrix of the same size. An important specification for these displays is their viewing-angle.

Twisted nematicdisplays contain liquid crystal elements which twist and untwist at varying degrees to allow light to pass through. A Super-twisted nematic(STN)display is a type of monochrome passive matrix LCD.STN displays provide more contrast than TN displays by twisting the molecules from 180 to 270 degrees. Film compensated Super-twisted nematic (FSTN) is a passive matrix LCD technology that uses a film compensating layer between the STN display and rear polarizer for added sharpness and contrast. It was used in laptops.

Pie chart depicts the revenue share of major technologies in the display market in 2010, which clearly indicates that TFT LCD is the leading technology and has maximum market share(92%) of the global display market.

After growing rapidly throughout the 2000s, industry revenues declined in both 2008 and 2009. While the immediate cause of this decline was the global recession, the display industry has also entered a mature phase. With notebook PCs and desktop monitors completely penetrated by TFT-LCDs, much of the growth in recent years has come from the TV market. Despite the recession, flat-panel-TV shipments grew on the order of 30% per year in 2008 and 2009. However, this growth is leading to high penetration rates, even in formerly emerging markets, such as China, and will push the flat-panel share of the TV market past 90% in 2011. This high penetration, combined with increasing pressure on prices, will lead to slower revenue growth, particularly for TFT-LCDs.

Large Area TFT - comprises of products that have a display size of more than 10 inches. The major applications for these displays are Television, Desktop Monitor and Notebook PC. Public displays comprises of only 2% share of the large area but is a growing sector.

Small & Medium TFT- comprises of products that have a display size of less than 10 inches The major applications for these displays are mobile phones and automotive displays. Digital cameras and Digital photo frames are also promising sectors in the future.

The revenue of overall TFT LCD market had gone down in the years 2008 and 2009 due to recession. Also, the share of Large area in these 2 years have gone down, as the demand for these high priced products had gone down.

Year on Year there was an increase in shipments for all the products of large area TFT LCD. In total the revenue grew by 25% in 2010 up from 20% in 2009. After recession and a laggard growth of 11.5% in 2008, the market has picked up and the revenue is growing.

Notebook PC market also looks profitable, with a growth rate of 31.7%, but a decline from the previous year from 36.6%. The OLED technology is eating up the market share of the TFT LCD market share in this market.

Here we observe that there is technology shift that is happening. Industry has moved from CRT to LCD now. The is shift has been gradual over the time.

Display Search forecasts that the plasma TV market will start shrinking in 2009 after hitting $24 billion in 2008, while it sees LCD TV demand reaching $75 billion in 2008 and $93 billion in 2010 - a trend that will likely make companies offering both LCD and plasma lines think twice about their strategy.

Sharp has recently developed 64 inch ultra high resolution direct view LCD with “ 4k *2k” one kind of digital cinema system specification- making it world’s first.

Sharp Corp. in August started LCD production at its Kameyama No. 2 plant, the world"s first to cut panels from eighth-generation glass substrates, which can yield eight 40-inch-class panels.

With escalating demand for larger fabs of Gen 8, Gen 8.5, and Gen 10, the liquid crystal display (LCD) and organic light emitting diode (OLED) manufacturing equipment market has witnessed a growth spur. The market will continue its upward growth trajectory through 2011, with the majority of demand stemming.

Under the belief that only technological development can secure the company"s survival and progress, Dongwoo Fine- Chem has been investing aggressively in the field of R&D. The company has built its main R&D center in Poseung Industrial Park in Pyeongtaek with an investment of 10 billon won for improving the quality of such LCD materials as color resists and polarized films in addition to electronics materials such as CMP slurries and color resists of next generation. In addition, the company constructed a new R&D center next to its already existent one in Iksan. The company has invested 7 billion won for the construction of Iksan research center furnished with ultramodern equipment.

The world"s largest LCD display manufacturer TPV Technology has signed an agreement with the Chengdu Hi-tech Zone to launch its R&D and production center in Chengdu, capital of Southwest China"s Sichuan Province. The center of an investment of $90 million is expected to start operation in 2012 and will reach its full capacity in five years, with an annual output of some 6 billion yuan, said officials from the zone.

The share of LCD TVs outsourced reached a record high of 34% in Q3"10, as Sony and LGE increased their outsourcing ratio to more than 50% and 20%, respectively.

In 2011, the top three panel makers, Samsung, LG Display, and Chimei Innolux, will be aggressive with their plan to ship more than 60 million units of LCD TV panels. In total, LCD TV panel makers plan to ship more than 270 million units in 2011.

Equipment/Material Suppliers: these are the industries which supply the basic material like ICs, Chemicals, and Liquid crystal etc. They help in putting the fundamental frame in place and start the process of manufacturing. They supply the basic and essentials parts required for the LCD.

Panel Makers: Panel makers are the companies which make basic Skeleton for product. They design the panels according to the demand and requirement. They play a major role as to design the basic frame. They are the players who design the basic technology like LCD, AMOLED etc. these are the companies which do most of the R&D in the technology to improve and introduce innovations.

LCD TV in the worldwide TV market has been well placed in the developed nations. However, there is an increase in the sales of LCD TV in the emerging countries as well.

Similarly, LG display(LGD) captures 20% market share of the TV OEM and 13% share of the market"s brand share. In the TV market, backward integration has worked for both Samsung and LGD.

Even though LG display(LGD) captures 24% market share of the Desktop OEM but only 9% share of the market"s brand share (behind Dell and HP), which shows it could not leverage the benefits of backward integration like Samsung in Desktop Monitor marketspectively.

Nokia captures 36% of the mobile market, but Nokia doesn"t produce its own mobile phone LCD panels but rather outsources it from other companies that produce the same.

Major segments of the LCD display technology were found out on the basis of the revenue and the shipments of each. 5 top segments were found out: Television, Desktop Monitor, Notebook PC, Mobile Phones and Automotive monitor displays. Automotive monitors are used for in-console navigation, controls and rear-seat entertainment.

Market sizes of each of the 5 segments on the basis of revenue were found out. Also the revenue share of the Total TFT LCD market was found out in order to calculate the share of each segment in the whole industry.

In 2009, Innolux Display acquired Taiwan LCD maker TPO Displays Corp. Then, Innolux acquired another Taiwan LCD maker, Chi Mei Opto electronics Corp. And recently, Innolux Display announced the completion of its acquisition of Chi Mei Optoelectronics and TPO Displays.

The new entity is called Chimei Innolux Corp. Chimei Innolux is now a dominant player in the global TFT-LCD panel market. It sells from 1.5- to 50-inch. panels. By essentially gaining control of Chimei Innolux, Foxconn can now offer customers a one-stop shop of contract manufacturing services, including LCD production.

Hisense and Konka have set up LCD-module assembly lines with the help of CMO; TCL set up an LCD-module assembly line using know-how transmitted from Samsung.

LG Display formed an alliance with AmTRAN to set up an LCD-module and LCD-TV-set assembly line and set up a joint venture with TPV for LCD-module lines.

The new entity would overtake Sharp as the largest maker of small and mid-sized LCD panels, which are commonly found in smartphones and tablet computers.

Though the market share of TFT LCD in the display market is predicted to reduce in the future, it would still capture more than 80% of the market. This presents ample of opportunity for existing players (currently producing semiconductor devices and want to enter LCD market) to use their technological excellence to milk the LCD market.

AMOLED technology is predicted to substitute TFT LCD in applications like smart phones and tablets. Hence for a new player, who plans to invest in R&D and manufacturing to enter the LCD industry, investing in better technology is advisable.

It is not advised for small players to enter the LCD industry as it is already in the consolidation phase. Many players like Samsung, have undergone vertical integration to optimize their costs. The initial investment required to enter the LCD industry is very high. In such a scenario, for a small player, who manufactures displays or products, will find it difficult to compete with giants like Samsung, LG etc on prices.

Players who have the expertise, capital and capacity to invest in LCD market can consider entering Mobile phones and Notebook PCs market. For them to succeed in the LCD market, they can either specialize in producing LCD displays with the latest and best technology available or consider vertical integration to optimize their cost.

Step 1. Using a Grove cable connect Grove - LCD RGB Backlight to Seeeduino"s I2C port. If you are using Arduino, please take advantage of a Base Shield.

HY-TFT320 is a 3.2 inch TFT LCD Screen module, 320*240 (resolution), 65K color, 34pins interface , not just a LCD breakout, but include the Touch screen, SD card. So it’s a powerful extension module for your project.

This Screen includes a controller SSD1289, it’s 16bit data interface, easy to drive by many MCU like STM32 ,AVR and 8051.HY-TFT320 is designed with a touch controller in it . The touch IC is XPT2046 , and touch interface is included in the 34 pins breakout. Another useful extension in this module is the SD Card socket . It use the SPI mode to operate the SD card, the SPI interface include in the 40pins breakout.

The UTFT library is required to be installed to get this screen model display. This library is especially designed for 3.2” TFT LCD screen using 16 bit mode. The library require the following connections.

Note: The TFT controller model needs to be declared in the initializing statement. ITDB02 myGLCD(38,39,40,41) needs to be modified as myGLCD(38,39,40,41,ITDB32S) when using Arduino Mega2560.ITDB02 myGLCD(19,18,17,16,ITDB32S) needs to be commented when using Aduino UNO. Otherwise it just show a blank screen. In practice, RS, WR, CS, RSET can be connected to any free pin. But the pin number must be in accord with myGLCD(RS,WR,CS,RST).

The LCD has a 3.2" 4-wire resistive touch screen lying over it. The Touch libraryneeds to be installed to get it works. This library is designed for 2.4’’ TFT, 3.2” TFT LCD screen module.

The default setting is accurate for 2.4” TFT module, but you need to calibrate when using 3.2” TFT module. A program to calibrate the touch screen is included in the example. If you touch screen is inaccurate, you need to run touch_calibration. Follow the on-screen instruction to calibrate the touch screen. Better not use your finger to calibrate it, use your accessory touch pen to pressure the frontsight with stength. Then record the calibration parameters and apply them in ITDB02_Touch.cpp in your touch screen library.

There is built-in SD card slot in the shield, so we can use it to upload images. But the images need to be converted RAW format first. SD libraries tinyFAT and tinyFAT_16 need to be preinstalled for displaying the image.
