In this article, we are looking at the benefits of looking for Chinese TFT LCD manufacturers. Instead of resorting to other manufacturing means, opting for the Chinese is a much wiser and lucrative choice. If you are looking for Chinese LCD manufacturers, you should start with STONE Tech.

Handbags, wallets, phone cases, and other similar items have become the favorites of wholesalers and bulk buyers. These products are directly sold to end consumers. However, the fascinating thing about the Chinese production and manufacturing business is that it does not only cover the end-consumer products. Rather, you can also acquire raw and basic materials needed for the further manufacturing of goods and products. One such product is LCD displays.

LCD displays have become something of a necessity in today’s world of tech advancement. Many things in our daily life have been automated, and are operated using an interactive user interface. For these kinds of machines and gadgets, LCD displays are typically necessary.

In this article, we are looking at the benefits of looking for Chinese LCD manufacturers. Instead of resorting to other manufacturing means, opting for the Chinese is a much wiser and lucrative choice. If you are looking for Chinese LCD manufacturers, you should start with Stoneitech.com.

STONE Tech is an LCD manufacturer located in Beijing, China. It was founded back in 2010, and it has been developing TFT LCD display modules ever since. These modules can be used for a variety of different machines including electric equipment, precision instruments, and civil electronics etcetera.

One of the main benefits that you get with Stoneitech.com is that there is a wide range of diverse products that you can purchase. For example, there are three different application types that you can choose from which include the Industrial Type, Advanced Type, and Civil Type. Similarly, there is a range of different sizes that you can choose from. There are 11 different sizes that you can buy, ranging from the smallest 3.5-inch display to the large 15.1-inch one. The same goes for the Android series which where you can choose between 4.5-inch and 31.5-inch displays.

This is probably the biggest advantage that you can get when working with manufacturers from China. It can even be assumed that this is probably the biggest reason why the Asian country is at the forefront of the mass manufacturing business.

In the initial period of your business, you want to build trust with your customers and give them more value than they expect. The best way you can achieve this is by making your products available for less than the average price. And this can only be done if you are saving up on costs yourself.

The same applies to LCD displays. When you save up on costs when buying LCD displays, you can set a lower price for the whole machine or gadget that you are producing.

This is a very useful benefit for small start-up companies. Generally, manufacturers in the USA are not going to be very willing to work with you unless you are a big company or unless you have a large recognition and following. Due to this, smaller companies can have trouble getting their demands heard. However, the refusal of suppliers to do so is not unjustified. Smaller companies are going to start off with smaller orders. Small orders are not very lucrative and beneficial for suppliers. The larger the order, the more convenient it will be for the manufacturer.

However, with Chinese manufacturers, this problem is minimized. The Chinese often don’t care how big a brand you are and what recognition your company has. As long as you meet the minimum order requirements, you can get your products easily. This is highly advantageous for smaller companies. Due to this, smaller firms can get started and kick off their business.

When it comes to LCD modules, the orders are not received by the hundreds or thousands as is the case with other smaller products such as handbags and wallets etcetera. One module can cost around $250, and it is for this reason that the dynamics are a little different with this business. That is why STONE offers single pieces for sale as well as multiple pieces. This encourages smaller businesses to make their purchases since they can easily purchase as many modules as they like. As long as you meet the limit stated by the supplier, you are good to go.

The factories in China have more machines and workers working simultaneously. This means that you can get bigger orders more quickly. For example, if you are getting 10 units from a domestic supplier in 4 days, you will be able to get 12 units from a Chinese supplier in just 3 days. That means that the production rate is increased, and the time taken is also cut short. This is merely an example to show that both aspects of production are enhanced when you do business with the Chinese.

Another great benefit of getting production done in China is the option for expansion. What that means is that while you can transport your merchandise to your home country, you also have the option of making them available in China. Instead of only bringing the goods back home to resell, you can set up a business that makes your merchandise available for sale in China as well.

In the case of LCD modules, this benefit relates to a reselling business. For example, if you are planning on buying some modules to use in your machines etcetera, then there is not a very suitable opportunity for you to expand. If you want to start a business in another country, you will have to open a manufacturing unit there so that your products can be produced and then get sold. Or, you will have to transport your final products to the other country in order to run your business.

However, if you are buying the LCD modules to resale at a profit, you can use the Chinese markets to grow your business. You can buy the modules at a reduced price and then sell them at a profit in a different area or city where the people will be willing to pay more.

Now that we have seen the benefits of choosing Chinese manufacturers for LCD modules, let us narrow it down a bit and look at why you should choose STONE specifically.

One of the main things that you have to look at in any supplier is the level of reliability and trust. This is usually determined by the level of experience and the time that the supplier has spent in the market. STONE was founded in 2010 and has been producing LCD modules for the past 10 years.

If you are looking to buy LCD modules in bulk, look no further than the Middle Kingdom. China has become the hub of mass manufacturing and is the favorite spot for wholesalers and business owners.

In case you need some convincing about buying from the Chinese, we have compiled a list of benefits that you can enjoy when looking for TFT LCD manufacturers in China.

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.

It achieved pixel response which was fast for its time, wide viewing angles, and high contrast at the cost of brightness and color reproduction.Response Time Compensation) technologies.

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.

When the field is on, the liquid crystal molecules start to tilt towards the center of the sub-pixels because of the electric field; as a result, a continuous pinwheel alignment (CPA) is formed; the azimuthal angle rotates 360 degrees continuously resulting in an excellent viewing angle. The ASV mode is also called CPA mode.

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 statements are applicable to Merck KGaA as well as its competitors JNC Corporation (formerly Chisso Corporation) and DIC (formerly Dainippon Ink & Chemicals). All three manufacturers have agreed not to introduce any acutely toxic or mutagenic liquid crystals to the market. They cover more than 90 percent of the global liquid crystal market. The remaining market share of liquid crystals, produced primarily in China, consists of older, patent-free substances from the three leading world producers and have already been tested for toxicity by them. As a result, they can also be considered non-toxic.

(Yicai Global) June 19 -- China National Building Material has built the country"s first production line capable of producing 8.5th-generation TFT-LCD glass substrates, making China one of few nations to master the technology.

The central state-owned firm"s Bengbu Glass Industry Design and Research built the facility after three years of research, Science and Technology Daily reported. The plant aims to obtain certifications that will allow it to manufacture for domestic display makers.

TFT-LCD, or thin-film-transistor liquid-crystal displays, are classified by the size of their glass substrate. Sixth-generation displays are now widely considered out-dated while 8.5th-gen tech is the most advanced. The newer technologies use larger substrates, which are more efficient to make and can be used in larger screens.

Demand for glass substrates in China reached 260 million square meters in 2018, with demand for 8.5th-gen components making up 233 million, according to the China Optics & Optoelectronics Manufacturers Association. But domestic production is only about 40 million square meters and all below 6th-gen. American and Japanese companies mostly dominate the more advanced segment of the market.

The association expects demand to surge to 300 million square meters by 2020, or about half of the global total, leaving massive room for development.

When compared to the ordinary LCD, TFT LCD gives very sharp and crisp picture/text with shorter response time. TFT LCD displays are used in more and more applications, giving products better visual presentation.

TFT is an abbreviation for "Thin Film Transistor". The colorTFT LCD display has transistors made up of thin films of Amorphous silicon deposited on a glass. It serves as a control valve to provide an appropriate voltage onto liquid crystals for individual sub-pixels. That is why TFT LCD display is also called Active Matrix display.

A TFT LCD has a liquid crystal layer between a glass substrate formed with TFTs and transparent pixel electrodes and another glass substrate with a color filter (RGB) and transparent counter electrodes. Each pixel in an active matrix is paired with a transistor that includes capacitor which gives each sub-pixel the ability to retain its charge, instead of requiring an electrical charge sent each time it needed to be changed. This means that TFT LCD displays are more responsive.

To understand how TFT LCD works, we first need to grasp the concept of field-effect transistor (FET). FET is a type of transistor which uses electric field to control the flow of electrical current. It is a component with three terminals: source, gate, and drain. FETs control the flow of current by the application of a voltage to the gate, which in turn alters the conductivity between the drain and source.

Using FET, we can build a circuit as below. Data Bus sends signal to FET Source, when SEL SIGNAL applies voltage to the Gate, driving voltage is then created on TFT LCD panel. A sub-pixel will be lit up. A TFT LCD display contains thousand or million of such driving circuits.

Topway started TFT LCD manufacturing more than15 years ago. We produce color TFT LCD display from 1.8 to 15+ inches with different resolutions and interfaces. Here is some more readings about how to choose the right TFT LCD.

TFT-based displays have a transistor for each pixel on the screen. This allows the electrical current that illuminates the display to be turned on and off at a faster rate, which makes the display brighter and shows motion smoother. LCDs that use TFT technology are called "active-matrix" displays, which are higher-quality than older "passive-matrix" displays. TFT technology provides the best resolution of all the flat display technologies, but it is also expensive than monochrome lcd. So TFTs are used in high-quality LCD displays, if you see a LCD monitor at your local computer market, it should be an active tft lcd display, Basically, it is a high-quality tft lcd monitor.

Passive-matrix display. A passive-matrix display is anLCD screen display that contains a series of wires that cross each other. See the dual scan display for a full definition on this term.

What is an Active-matrix Display (TFT)? Alternatively referred to as TFT ( thin-film transistor) and AMLCD ( active-matrix LCD ), an active-matrix display is an LCD ( liquid crystal display) introduced with the IBM ThinkPad in 1992.

It uses a matrix of thin film transistors(TFTs) and capacitors to control the image produced by thedisplay. The brightness of each pixel is controlled by modifying the electrical charge of the corresponding capacitors.

Last week, Sharp announced that it will expand its alliance with CEC (China Electronics Corp.), the parent company of CEC-Panda, a Chinese TFT LCD panel maker. Sharp sold its Gen 6 line to CEC-Panda back in 2011, and now has decided to play an important role in CEC-Panda’s planned Gen 8 TFT LCD fab in Nanjing. Nanjing CEC-Panda LCD Technology Co., with 17.5 billion RMB ($2.9 billion) in capital, will be a joint venture between CEC Group (92 percent) and Sharp (8 percent), the first joint Chinese-Japanese TFT LCD fab. This follows Samsung and LG Display’s efforts to build Gen 8 fabs in China through joint ventures with TCL and Skyworth, respectively.

With smart handheld devices (smartphones and tablet PCs) growing faster than LCD TV, CEC-Panda is planning to shift its business focus from TV to smart handheld device panels, which require high resolution, slim form factor, low color shift, high color saturation and low power consumption. This shift requires high performance technologies and processes, which Sharp can provide.

Sharp will benefit from the cash flow coming from royalty and technology transfer income, and will have first priority for the allocation of the output of the Gen 8 fab.

Sharp is the first to implement oxide TFT (in particular IGZO) technology for handheld devices, in order to achieve low power consumption and high resolution. Sharp may implement IGZO technology in Nanjing, not only to help the joint venture company to ramp up high resolution panels, but also to collect royalties from any IGZO production.

As we have analyzed, by 2015, there will be 8 Gen 8 fabs in China, at which point China will have the most Gen 8 capacity; one of these will be the CEC-Panda/Sharp line. As the LCD TV market matures, some of these fabs will start to produce high-resolution smart handheld device panels.

Taiwanese panel makers might be further marginalized and forced to reshape their strategy toward the China market. Taiwan panel makers are the largest suppliers to China at present, with LCD TV panels supplied by AUO and Innolux, and smartphone and tablet PC panels supplied by HannStar and CPT. However, with Korean and Japanese makers invested in China, Taiwanese panel makers will be the only ones facing import duties. Taiwan panel makers will be forced to make additional panel cost reductions or somehow create a unique offering in China (such as new TV sizes, or large but lower resolution smart handheld panels).

CEC-Panda is not recognized as a leading panel maker due to its limited product mix (monitor panels and 32” in Gen 6) and lagging technology. The company has no experience in high resolution (like 4Kx2K) TV panels or smart device panels. However, with help from Sharp, CEC-Panda may become a competitor for high-end panels.

As a display device TFT stands for Thin Film Transistor and is used to enhance the operation and usefulness of LCD displays. An LCD is a fluidic display device that uses a crystalline filled liquid to manipulate a rear illumination polarized source by means of an electrostatic field between two thin transparent metal conductors such as indium tin oxide (ITO) in order to present an image to the viewer. This process can be used in both segmented or pixelated display devices but is found synonymous with color TFT displays.

When an LCD is used to display moving images the inherent slow rate of change between fluid states over a large number of pixel elements can be a problem due in part to capacitive effects, which causes moving image blurring. By putting a high speed LCD controlling device in the form of a thin film transistor right at the pixel element on the glass surface, the LCD image speed issue can be greatly enhanced and for all practical purposes eliminates image blurring.

Other benefits of these thin film transistors are they allow for thinner display designs and different pixel designs and arrangements to vastly improve display viewing angles.

TFT displays are found in many applications these days, from mobile devices, appliance, medical devices, instrumentation, aircraft and certainly computer display devices as well as TV’s. The addition of the thin film transistor in LCD design vastly improved the use of LCD’s in all market areas.

The economic rebound in the first quarter of 2009 was mainly due to LCD TV. The economic recession of Europe and America will only make consumers reduce the consumption on such necessities in the late phase. Although Europe and America suffered economic recession, the market shares of LCD TV did not fluctuate much because of manufacturers’ promotion strategies, WON depreciation and further development of LCD TV in the first quarter of 2009. With the push of China and other emerging countries, the market rebounded significantly. Japanese enterprises were panicked and reduced production greatly when economic recession arose, resulting in short supply. This strong rebound was still lack of powerful support, especially in emerging countries. In China, when the property market begins to rebound, real estate sales will promote the consumption on home appliances. In the mid and late rebound phase of the property market, consumers will wait and see, and real estate sales will decline, so that home appliances consumption will also drop. The unemployment rate is still rising in Europe and America and economic recession has not ended, so if consumers are aware of the fact, they will certainly cut expenditure.

From Q1 2005 to Q4 2010, the fluctuation of TFT-LCD industry seems to be magnified, but the fact is not. The global economy has experienced the most significant recession since the Great Depression in 1929. TFT-LCD industry is the upstream of consumer electronics and IT industry, and the two industries always follow the trend of the global economy. Excluding external factors, the fluctuation of TFT-LCD industry is lessened, especially the extent of decline shrinks, which is because LCD TVs develop rapidly, IT industry is relatively stable and notebook computers develop well. Before 2000, 80% of TFT-LCDs were used in notebooks, thus on which TFT-LCD industry was highly dependent, and then TFT-LCD industry fluctuated a lot. In the future, LCD TV industry, Netbook industry and LED notebook industry will enter the mature stage, which will make TFT-LCD industry tend to fluctuate less, but on the other hand, the industry will lack growth momentum.

TFT-LCD industry relies heavily on upstream raw materials and components. In the cost structure of TFT-LCD, upstream components account for 70-85%. Therefore, to be cost-efficient shall be supported by the strong upstream, but for Chinese enterprises, it is hard to do so. In many Chinese enterprises, including joint ventures, profit is often transferred to the upstream. In addition to glass substrates, Taiwan has nearly all of upstream industrial chains, which is the biggest driver for Taiwan"s success in TFT-LCD industry. TFT-LCD industry can prompt a huge industrial chain. Japanese manufacturers occupy the top position in the industrial chain, and they usually sell their technology rather than products. Almost every Taiwanese manufacturer in the upstream industrial chain has received technical support from Japan, so do South Korea manufacturers. Taiwanese manufacturers’ success lies in fast access to market through technology licensing, while Japanese manufacturers rely on supporting Taiwanese enterprises to combat South Korea rivals. Japanese manufacturers still master the upstream firmly.

As for non-key components, these companies have adequate resources, especially AUO and Chimei. Mainland China enterprises invest on the middle and downstream which brings production value fastest, but they neglect the efficiency and quality of the investment, and thus lack cost competitiveness.

After forty years of development, the global satellite navigation system has developed into a “one plus three” pattern. And the “one” refers to GPS made in the USA, and the three refer to Chinese, Rus...

Dr Pan: Hello, Greg. TFT LCD module is one of the best LCD technology. We can simply consider it as TFT+LCD+LED backlight, and monochrome LCD module consists of LCD+LED backlight. An image on an LCD we can see is composed of pixels. TFT is the abbreviation for thin film transistor and it controls the R, G, B colors of each pixel respectively on the surface of LCD.

TFT LCD is a high standard product and it is not well customized as monochrome LCD. But still, it has a variety of options to meet the customers’ requirements.The sizes range from 1.44 inch to 130.0 inch;

When compared to the ordinary LCD, TFT LCD gives very sharp and crisp text/graphic with shorter response time. TFT LCD displays are used in more and more applications, giving products better visual presentation.

TFT is an abbreviation for "Thin Film Transistor". The color TFT LCD display has transistors made up of thin films of Amorphous silicon deposited on a glass. It serves as a control valve to provide an appropriate voltage onto liquid crystals for individual sub-pixels. That is why TFT LCD display is also called Active Matrix display.

A TFT LCD has a liquid crystal layer between a glass substrate formed with TFTs and transparent pixel electrodes and another glass substrate with a color filter (RGB) and transparent counter electrodes. Each pixel in an active matrix is paired with a transistor that includes capacitor which gives each sub-pixel the ability to retain its charge, instead of requiring an electrical charge sent each time it needed to be changed. This means that TFT LCD displays are more responsive.

To understand how TFT LCD works, we first need to grasp the concept of field-effect transistor (FET). FET is a type of transistor which uses electric field to control the flow of electrical current. It is a component with three terminals: source, gate, and drain. FETs control the flow of current by the application of a voltage to the gate, which in turn alters the conductivity between the drain and source.

Using FET, we can build a circuit as below. Data Bus sends signal to FET Source, when SEL SIGNAL applies voltage to the Gate, driving voltage is then created on TFT LCD panel. A sub-pixel will be lit up. A TFT LCD display contains thousand or million of such driving circuits.

Topway started TFT LCD manufacturing more than15 years ago. We produce color TFT LCD display from 1.8 to 15+ inches with different resolutions and interfaces. Here is some more readings about how to choose the right TFT LCD.
