TFT stands for thin-film transistor, which means that each pixel in the device has a thin-film transistor attached to it. Transistors are activated by electrical currents that make contact with the pixels to produce impeccable image quality on the screen. Here are some important features of TFT displays.Excellent Colour Display.Top notch colour contrast, clarity, and brightness settings that can be adjusted to accommodate specific application requirements.Extended Half-Life.TFT displays boast a much higher half-life than their LED counterparts and they also come in a variety of size configurations that can impact the device’s half-life depending on usage and other factors.TFT displays can have either resistive or capacitive touch panels.Resistive is usually the standard because it comes at a lower price point, but you can also opt for capacitive which is compatible with most modern smartphones and other devices.TFT displays offer exceptional aspect ratio control.Aspect ratio control contributes to better image clarity and quality by mapping out the number of pixels that are in the source image compared to the resolution pixels on the screen.Monitor ghosting doesn’t occur on TFT displays.This is when a moving image or object has blurry pixels following it across the screen, resembling a ghost.

TFT displays are incredibly versatile.The offer a number of different interface options that are compatible with various devices and accommodate the technical capabilities of all users.

There are two main types of TFT LCD displays:· Twisted nematic TFT LCDs are an older model. They have limited colour options and use 6 bits per each blue, red, and green channel.

In-plane switching TFT LCDs are a newer model. Originally introduced in the 1990s by Hitachi, in-plane switching TFT LCDs consist of moving liquid pixels that move in contrast or opposite the plane of the display, rather than alongside it.

The type of TFT LCD monitor or industrial display you choose to purchase will depend on the specifications of your application or project. Here are a few important factors to consider when selecting an appropriate TFT LCD display technology:Life expectancy/battery life.Depending on the length of ongoing use and the duration of your project, you’re going to want to choose a device that can last a long time while maintaining quality usage.

Touch type and accuracy.What type of activities are you planning on using your device for? If it’s for extended outdoor use, then you should go with projected capacitive touch as this is more precise and accurate. Touch accuracy is important for industrial and commercial applications.

Image clarity.Some TFT displays feature infrared touchscreens, while others are layered. The former is preferable, especially in poor lighting conditions or for outdoor and industrial applications, because there’s no overlay and therefore no obstructions to light emittance.

The environmental conditions make a difference in operation and image clarity. When choosing a TFT for outdoor or industrial applications, be sure to choose one that can withstand various environmental elements like dust, wind, moisture, dirt, and even sunlight.

TFT (Thin Film Transistor) LCD (Liquid Crystal Display) we are talking here is TN (Twisted Nematic) type TFT displays which is align with the term in the TV and computer market. Now, TFT displays have taken over the majority of low-end color display market. They have wide applications in TV, computer monitors, medical, appliance, automotive, kiosk, POS terminals, low end mobile phones, marine, aerospace, industrial meters, smart homes, consumer electronic products etc. For more information about TFT displays, please visit our knowledge base.

Talking about Pros and Cons of TFT displays, we need to clarify which display they are compared to. To some displays, TFT displays might have advantages, but compared with another display, the same character might become the disadvantages of TFT displays. We will try our best to make clear as below.

Less Energy Consumption: Compared with CRT(Cathode-Ray Tube) VFD ( Vacuum Fluorescent Display) and LED (Light Emitting Diode) display, which made laptop possible.

Excellent physical design. TFT displays are very easy to design and integrated with other components, such as resistive and capacitive touch panels (RTP, CTP, PCAP) etc.

Minimum Eye Strain: Because TFT panel itself doesn’t emit light itself like CRT, LED, VFD. The light source is LED backlight which is filtered well with the TFT glass in front for the blue light.

More Energy Consumption: Compared with monochrome displays and OLED (PMOLED and AMOLED) display, which makes TFT displays less attractive in wearable device.

Poor response time and viewing angle: Compared with IPS LCD displays, AMOLED displays and recent micro-LED display. TFT displays still need to note viewing angle of 6 o’clock or 12 o’clock in the datasheet and still have the gray scale inversion issue.

High tooling cost: Depending on which generation production line to produce and also depending on its size. Building a TFT display fab normally need billions of dollars. For a big size display which needs high generation production line to produce. The NRE cost can be millions dollars.

Sunlight Readability: Because it is very expensive to produce transflective TFT LCD displays, in order to be readable under the sunlight, very bright LED backlight (> 1,000 nits) has to be used. The power needed is high and also need to deal with heat management. If used together with touch panel, expensive optical bonding (OCA or OCR) and surface treatment (AR, AF) technologies have to be used.

IPS (In-Plane Switching) lcd is still a type of TFT LCD, IPS TFT is also called SFT LCD (supper fine tft ),different to regular tft in TN (Twisted Nematic) mode, theIPS LCD liquid crystal elements inside the tft lcd cell, they are arrayed in plane inside the lcd cell when power off, so the light can not transmit it via theIPS lcdwhen power off, When power on, the liquid crystal elements inside the IPS tft would switch in a small angle, then the light would go through the IPS lcd display, then the display on since light go through the IPS display, the switching angle is related to the input power, the switch angle is related to the input power value of IPS LCD, the more switch angle, the more light would transmit the IPS LCD, we call it negative display mode.

The regular tft lcd, it is a-si TN (Twisted Nematic) tft lcd, its liquid crystal elements are arrayed in vertical type, the light could transmit the regularTFT LCDwhen power off. When power on, the liquid crystal twist in some angle, then it block the light transmit the tft lcd, then make the display elements display on by this way, the liquid crystal twist angle is also related to the input power, the more twist angle, the more light would be blocked by the tft lcd, it is tft lcd working mode.

A TFT lcd display is vivid and colorful than a common monochrome lcd display. TFT refreshes more quickly response than a monochrome LCD display and shows motion more smoothly. TFT displays use more electricity in driving than monochrome LCD screens, so they not only cost more in the first place, but they are also more expensive to drive tft lcd screen.The two most common types of TFT LCDs are IPS and TN displays.

TFT displays have become increasingly common in our daily lives. They are used in cars, laptops, tablets, and smartphones, as well as in industrial applications and many more. But what are TFT displays and why are they so important?

A TFT (Thin Film Transistor) display is a type of display technology that uses a thin layer of transparent material to produce an image on the screen. The display is made up of thin layers of organic material called organic transistors, which are stacked together on a glass substrate and covered with a thin layer of plastic or metal oxide.

TFT displays are also used in many other industrial applications, such as industrial control systems, medical devices, automotive infotainment systems, and more.

The basic concept behind a TFT display is simple: it uses light to create an image on a screen. Light passes through the glass substrate and the organic transistors until it reaches the top layer of the display.

The organic transistors turn on and off in response to the electrical charge of light passing through them. As they do so, they produce voltages that are then sent through wires connected to each pixel of the screen to create an image.

The number of pixels that can be displayed depends on how many organic transistors are used in each pixel or subpixel (a single-pixel is made up of multiple subpixels). For example, a 4-inch (10 cm) display has a pixel pitch of 0.0625 inches (1.57 mm).

The basic design of a TFT display has remained unchanged for more than 20 years. In this design, the sub-pixels are arranged in a grid pattern, with each subpixel connected to its neighbor by wires that form rows and columns.

The number of wires per pixel depends on the size and resolution of the screen: the larger and higher resolution of the screen, the fewer wires need to be used.

In 1982, Sanyo introduced the world’s first 16-inch (40 cm) LCD with a resolution of 640×480 pixels. This was followed by the introduction of 30-inch (76 cm) screens in 1984 and 40-inch (100 cm) screens in 1985.

The first large format TFT display was introduced in 1987 by NEC Corporation, which used a 1024×768 pixel screen for its PC monitor line, called CRT Professional Display System or “Videotronic” system. The technology was licensed to NEC’s competitors such as Hitachi and Toshiba for use in their own monitors and televisions. The system was marketed as “Super Video” and replaced the aging “Videotron” CRT monitors that were still being used at the time. The first LCD TV was also produced in 1987 by Sony.

In 1989, Sharp’s first TFT-LCD TV set was introduced with a resolution of 576×320 pixels, while the world’s first large format high definition screen with a resolution of 1024×768 pixels was introduced by NEC in 1994.

Over the years, TFT display technology has developed by leaps and bounds. It has been used in tablets, smartphones, notebooks, game consoles, and computer monitors. The technology is also used in digital cameras, camcorders, MP3 players, and GPS devices.

What does the TFT display technology comprise? From far, you can easily assume TFT to be a single unit. But in reality, it comprises different components that work together.

The backlight of the TFT display is a very important component. It provides the light for the pixels and is also responsible for illuminating the display. The light emitted by a backlight can be controlled by varying the amount of current running through it.

When it comes to LCD displays, there are two types of backlights; Active matrix and Passive matrix. Active matrix backlight has several layers of electrodes, which are used to control the amount of current flowing through them.

Whereas, Passive matrix backlight consists of one electrode layer that acts as a switch between off and on states. The active matrix backlights are more expensive than passive-matrix ones because they require more power to operate.

The pixel is the smallest unit in a TFT display. It is the basic unit of information that is displayed on the screen. The pixel consists of three sub-elements, namely; Red, Green, and Blue (RGB).

The number of sub-pixels that are used in each pixel varies with different display technologies. In full-color LCDs, there are three types of sub-pixel: red, green, and blue (RGB). Full color TFT displays use a combination of Red, Green, and Blue (RGB) sub-pixels to represent full color.

The backplane and frontplane are connected by a number of flexible printed circuits. The PCBs are usually connected to each other with wires made from metals such as copper or aluminum. These wires are used to supply power, data, and control signals between the backplane and the front-plane.

The light that is transmitted through each TFT is controlled by applying voltages of different values to each pixel in turn. To do this, a control circuit called a driver circuit is required. The driver circuit controls the voltage applied to each pixel with reference to a set of parameters known as “pixel information”.

This information includes color, brightness, and other characteristics that define how an individual pixel should be operated for display purposes. The parameters also include how many red, green and blue sub-pixels are used to produce each pixel.

The control system can be further divided into 3 sub-systems: the interface, the timing, and the data transfer system (DTS). These systems work together to provide all of the necessary functions for controlling TFT displays from external sources such as computers, printers, or TVs.

This is another component of a TFT display system. It consists of a liquid crystal material sandwiched between two glass plates. This material is responsible for controlling the light by changing its refractive index.

-Wide viewing angle: The viewing angle of the TFT display is larger than that of the CRT set. It is generally considered to be the best choice for applications requiring an extended viewing angle.

-Transparency: TFT display has better transparency than CRT set, which makes it more suitable for applications requiring high transparency such as window displays and computer monitors.

-High resolution: TFT display can produce higher resolution than CRT display. For example, the pixel density of TFT is about 3 million pixels per square inch (PPI), which is about three times that of conventional liquid crystal displays (LCDs) whose pixel density is about 100 ppi.

-Reliability: Since it uses no moving parts, the TFT screen does not need any maintenance or repair, and therefore the reliability is higher than that of LCDs and plasma displays.

-Power saving: TFT display consumes much less power than CRT. The power consumption of a mainstream TFT display is about 1/10 that of a typical LCD. In some applications, the power consumption can be reduced to 1/100 or less of that of a CRT.

-High brightness: The picture displayed on the screen can be bright enough to be seen in bright sunlight without any need for glare reduction filters.

-Compatibility: Since it uses no moving parts, the TFT screen does not have any mechanical problems such as screen flicker and image sticking problems found in plasma displays and LCDs.

-High resolution: Although the pixel density of TFT is about 3 million pixels per square inch (ppi), the resolution is more than 100 ppi which makes it more suitable for many applications where high resolution is needed.

-Consistency: Since it uses no moving parts, the image displayed on the TFT display is not affected by temperature and humidity, which makes it more consistent than LCDs and plasma displays.

-Cost: The cost of a TFT display is lower than that of LCDs and plasma displays. For example, in some applications where image quality is not critical, the cost of a TFT display may be only a few tens to a few hundreds of dollars while the cost of LCDs or plasma displays may be several thousand to several tens of thousands.

-Excellent color display: We can’t deny the fact that TFTs have a superior color display. This simply means that the color of pixels can be accurately reproduced.

-Very thin: When compared with LCDs and plasma displays, which are very thick, TFTs are very thin and lightweight. In addition, the cost of mounting a large size TFT screen to a wall panel is relatively low.

-No ghosting: ‘Ghosting’ refers to the fact that the display shows a bright spot on the screen when the screen is turned off. TFT screens do not show ghosting. TFTs produce a sharp image even when they are turned off.

-No geometric distortion: Geometric distortion refers to the shape of the display on a flat surface. TFTs produce a sharp image even when they are turned off.

-No radiation: TFTs do not emit any harmful radiation, and there is no need for shielding or shielding materials to protect people from harmful radiation.

Considering that TFTs use less power, it is possible to reduce energy consumption by up to 50% compared with LCDs. In addition, if you use LED backlights in TFT displays, you can reduce power consumption by up to 75% compared with conventional backlights.

The screen quality of a product can be improved by reducing scratches on the screen surface caused by friction between the screen surface and fingers or objects that come into contact with it during daily use (e.g., keys). In addition, the life cycle of a product can be increased by reducing the possibility of product damage due to scratches on the screen surface.

If a product uses a backlight, there is a high possibility that the color of the screen will be affected after some time due to dust or dirt that comes into contact with it. But it is possible to prevent this problem by using TFTs with LED backlights, which have no problems such as those caused by dust and dirt.

It is possible to reduce power consumption and extend product life by reducing backlight power consumption and extending product life. In addition, if you use LEDs for backlights, you can reduce power consumption by up to 75% compared with conventional backlights.

Workability refers to the ease with which you can operate a product. When working with a screen that has TFTs, it is possible to increase the amount of information that can be displayed at one time. It is also possible to reduce the number of times you must change settings on a product by increasing its usability.

Design refers to what you can create with the use of a product. Using TFTs, it is possible to create products that have a thin profile and are lightweight, which makes them more convenient for transportation and storage.

Human interface refers to what you touch when using a product or what you see on the screen when using a product (e.g., buttons and other controls). By integrating the TFTs into the display part of a product, it is possible to make the human interface easier.

Amoled refers to a technology that replaces the traditional liquid crystal display (LCD) with an organic light-emitting diode (OLED). Modern TFTs are similar to Amoled in terms of their structure, but they differ from Amoled in terms of their performance.

The TFTs of the present invention have superior characteristics compared to Amoled, such as high contrast ratio and response speed. The TFTs also have superior characteristics compared to conventional display devices such as CRT and plasma display panels, which cannot be achieved by these conventional display devices.

IPS refers to a technology that replaces the traditional liquid crystal display (LCD) with in-plane switching technology. The IPS display has superior features to TFT due to its high contrast ratio, wide viewing angle, and high response speed.

There are certain limitations to TFTs. For example, there is a limit to the size of the display and the resolution of the image that can be displayed on a display. Also, because TFTs are considered to be a kind of organic semiconductor displays, they have a short life span and therefore need frequent replacement.

Because of their high resolution, TFT displays are used in display monitors. The type of TFT used in display monitors can be categorized as either active matrix or passive matrix. Active matrix TFTs use a thin film transistor (TFT) as its active component, whereas passive matrix uses a liquid crystal display (LCD).

TFTs are also being used in portable electronic devices such as mobile phones, personal digital assistants (PDAs), and cameras. These devices require high-resolution screens because the user must be able to view accurate images and text on the screen. TFTs are also being used in laptops, which have a much larger screen size than many other portable electronic devices.

Because of their size and high resolution, laptop computers use passive matrix TFT displays instead of LCDs for larger displays than those found on smaller-sized portable electronics devices that use LCDs for their displays (e.g., mobile phones and PDAs).

TFT displays are used in front-projection TVs. The type of TFT used in front-projection TVs can be categorized as either active matrix or passive matrix. Active matrix TFTs use a thin film transistor (TFT) as its active component, whereas passive matrix uses a liquid crystal display (LCD).

Head-mounted displays (HMDs) use liquid crystal on silicon technology to create small, inexpensive, low-power VR headsets that can be worn on the head. Some HMDs use active matrix TFT technology while others use passive matrix TFT technology. Active matrix HMDs use shorting bars or glass electrodes to control each pixel; passive matrix HMDs use a liquid crystal material that allows for the creation of an image by controlling the voltage applied to each pixel.

TFTs are used in projectors to create the on-screen image from the input signal. TFTs are used in both active matrix and passive matrix projectors. Active matrix projectors use shorting bars or glass electrodes to control each pixel, while passive matrix projectors use a liquid crystal material that allows for the creation of an image by controlling the voltage applied to each pixel.

CCDs are used in digital cameras and DV camcorders to capture still images and video, respectively. CCDs use a single array of photosites that each receives an electrical charge during exposure to light, resulting in an electrical signal that is output as an image. TFTs are used in CCDs as display circuits for previewing pictures.

TFTs are used in the display of gaming systems such as consoles, personal computers, and hand-held devices. TFTs are also used in the display of mobile telephones and in digital signs.

There are many factors to consider when buying a TFT display. The most important factors are the size of the display, the resolution of the display, and whether or not it is touch-sensitive.

It is also vital to consider where you are buying your TFT display system. A good place to buy a TFT display is from an authorized dealer or an online store. You should also consider whether or not the TFT display system you are looking for has a warranty.

Technology can be confusing because it evolves quickly, and there are complex acronyms for almost everything. If you are thinking ofbuildinga monitor or want to learn about the technology, you will encounter the term TFT Monitor at some point.

A lot goes on behind the glass surface, and we will look at this in comparison to other technologies to paint a clear picture of what TFT is and how it evolved.

TFT is an acronym for Thin Film Transistor, and it is a technology used in Liquid Crystal Display screens. It came about as an improvement to passive-matrix LCDs because it introduced a tiny, separate transistor for each pixel. The result? Such displays could keep up with quick-moving images, which passive-matrix LCDs could not do.

Also, because the transistors are tiny, they have a low power consumption and require a small charge to control each one. Therefore, it is easy to maintain a high refresh rate, resulting in quick image repainting, making a TFT screen the ideal gaming monitor.

The technology improved on the TN (Twisted Nematic) LCD monitor because the shifting pattern of the parallel, horizontal liquid crystals gives wide viewing angles. Therefore, IPS delivers color accuracy and consistency when viewed at different angles.

Both TFT and IPS monitors are active-matrix displays and utilize liquid crystals to paint the images. Technically, the two are intertwined because IPS is a type of TFT LCD. IPS is an improvement of the old TFT model (Twisted Nematic) and was a product of Hitachi displays, which introduced the technology in 1990.

The monitors can create several colors using the different brightness levels and on/off switches. But unlike OLED, both TFT and IPS do not emit light, so most have bright fluorescent lamps or LED backlights to illuminate the picture. Also, neither of them can produce color, so they have an RGB color filter layer.

Easy to Integrate and Update: By combining large-scale semiconductor IC and light source technology, TFTs have the potential for easy integration and updating/development.

Wide Application Range: TFTs are suitable for mobile, desktop screens, and large-screen TVs. Additionally, the technology can operate at a temperature range of -20°C to +50°C, while the temperature-hardened design can remain functional at temperatures not exceeding -80°C.

Impressive Display Effect: TFT displays use flat glass plates that create an effect of flat right angles. Combine this with the ability of LCDs to achieve high resolutions on small screen types, and you get a refreshing display quality.

High Resolution: The technology combines high brightness, color fidelity, contrast, response speed, and refresh rate to ensure you get a high resolution.

Good Environmental Protection: The raw materials used to make TFT displays produce zero radiation and scintillation. Thus, the technology does not harm the user or the environment.

Mature Manufacturing Technology: TFT technology came into existence in the 60s. Over time, its manufacturing technology has matured to have a high degree of automation, leading to cheaper, large-scale industrial production.

Wide View Angle: One of the main advantages of IPS screens is their wide viewing angle due to the horizontal liquid crystals. They do not create halo effects, grayscale, or blurriness, but these are common flaws with TFTs.

Better Color Reproduction and Representation: The pixels in TFTs function perpendicularly after activation with the help of electrodes. However, IPS technology makes the pixels function while parallel horizontally. Thus, they reflect light better and create a more original and pristine image color.

Faster Frequency Transmittance: Compared to TFT, IPS screens transmit frequencies at about 25ms, which is 25x faster. This high speed is necessary to achieve wide viewing angles.

Liquid Crystal Display (LCD) is a front panel display that utilizes liquid crystals held between two layers of polarized glass to adjust the amount of blocked light. The technology does not produce light on its own, so it needs fluorescent lamps or white LEDs.

As explained earlier, TFT improved on the passive-matrix LCD design because it introduces a thin film transistor for each pixel. The technology reducescrosstalkbetween the pixels because each one is independent and does not affect the adjacent pixels.

LED screens are like the new kids on the block in the display market, and they operate very differently from LCDs. Instead of blocking light, LEDs emit light and are thinner, provide a faster response rate, and are more energy-efficient.

Since IPS is a type of TFT, when comparing the two, we are essentially looking at the old Thin-Film Transistor technology (Twisted Nematic) vs. the new (IPS). Even though TN is relatively old, this digital display type has its advantages, a vital one being the fast refresh rate. This feature makes such screens the preferred option by competitive gamers.

The worlds of high-end Color LCD Modules are taken over. As our world evolved and embedded devices becoming more, and more sophisticated and prevalent, we tend to look at the art of design. Steve Jobs sums it up just right. “Design is not just what it looks like and feels like. Design is how it works.” TFT LCD modules are a type of variant of an LCD which uses thin film, appliances such as: TV, computer monitors, kindles, mobile phone, and navigation system. The construction of a color LCD module or TFT LCD is quite extraordinary because of the circuit layout process; this form of layout is similar to the layout of a semiconductor product. Even though as we observe the TFT LCD display we came across few pros and cons which are most needed for this discussion. The advantages of TFT LCD are as follows: less energy consumption, visibility is sharper in other words has superb quality, physical design, response time, and less eye strain etc… With every great product there are few disadvantages associated, such as, cost and viewing angles.

TFT LCD displays are very convenient because of the energy consumption associate with this display, knowingly in today’s society saving energy is a number one priority to reduce greenhouse gas and ensure a better future generations. Due to the construction of TFT structures Pixel like materials does not consume much energy to begin with except this material consume far less power than a comparable CRT monitor. The images of a TFT display does not rely on the scanning of electron beams instead they are free from flicker and has a crisp image, with no geometric distortion. The physical design of TFT display are space savors which can be position anywhere in ones office, or house with a rotations mechanism in place for less constrains on space.

As mention before TFT LCD has few disadvantages, due to the nature of the design TFT LCD display may cost a little more than a regular monochrome display. Other disadvantages may arise when the viewing the display at the 6 0’clock direction but in fact the optimal viewing is at the 12’oclock direction this may also lead to inversion which or common in situation like this; however TFT displays are superior and will be in production for years to come.

Because every point on the TFT LCD screen maintains that color and brightness after receiving the signal, it glows at a constant rate, rather than constantly refreshing the bright spots as the cathode ray tube display (CRT) does. As a result, the TFT LCD is of high quality and does not flicker, reducing eye fatigue to a very low level.

For displays of the same size, the visual area of the TFT LCD screen is larger. The visible area of the TFT LCD is the same as its diagonal size. Cathode ray tube display screen picture tube front panel around an inch or so of the border can not be used for display.

The original LCD screen is usually used in electronic watches and calculators because it is unable to display delicate characters. With the continuous development and progress of liquid crystal display technology, character display begins to be exquisite, but also supports the basic color display, and gradually used in liquid crystal TV, camera liquid crystal display.

The subsequent DSTN and TFT were widely made into liquid crystal display devices in computers, and DSTN LCD screens were used in early notebooks. TFT is used not only on laptops (most laptops now use TFT displays), but also on mainstream desktop displays.

The display material of the traditional display screen is phosphor, which is shown by the impact of the electron beam on the phosphor. The electron beam produces strong electromagnetic radiation in the moment it hits the phosphor. Although there are many display products in dealing with the radiation problem more effectively, as far as possible to reduce the amount of radiation to a very low, but to completely eliminate it is difficult. Relatively speaking, the TFT LCD screen has an innate advantage in preventing radiation because it does not exist at all.

In the aspect of electromagnetic wave prevention, TFT LCD screen also has its own unique advantages. It uses strict sealing technology to seal a small number of electromagnetic waves from the driving circuit in the display, while ordinary displays in order to emit heat. The internal circuit must be in contact with the air as much as possible so that the electromagnetic waves generated by the internal circuit "leak" outward in large quantities.

TFT LCD screens are digital and do not use analog interfaces like cathode ray tube color displays. In other words, with the TFT LCD, the graphics card no longer needs to convert the digital signal into an analog signal and output it as usual. In theory, this would make the color more accurate and perfect.

A traditional cathode ray tube display is always dragged behind a bulky ray tube. The TFT LCD breaks through this limit and gives a whole new feel. The traditional display screen emits electron beam to the screen, so the neck of the picture tube can not be very short, when the screen increases, it is necessary to increase the size of the whole display.

On the other hand, the TFT LCD screen controls the liquid crystal molecular state through the electrode on the display screen to achieve the display purpose. Even if the screen is enlarged, its volume will not increase in direct proportion, and its weight is much lighter than the traditional display with the same display area.

Compared with the traditional display screen, the TFT LCD screen starts with a pure flat glass panel, and its display effect is flat at right angles, giving people a refreshing feeling. And it is easier for LCD to achieve high resolution on a small screen. For example, a 17-inch LCD can achieve a good resolution of 1280 × 1024. On the other hand, the effect of using a resolution of more than 1280 × 1024 on an 18-inch CRT color display is not entirely satisfactory.

The traditional display screen is composed of many circuits. When these circuits drive the cathode ray picture tube, they need to consume a lot of power, and with the continuous increase of the volume, the power consumed by the internal circuit will certainly increase. In contrast, the power consumption of TFT LCD is mainly consumed by its internal electrode and driver IC, so the power consumption is much smaller than that of traditional display.

Display size, contrast, color, brightness, resolution, and power are key factors in choosing the right display technology for your application. However, making the right choice in how you feed the information to the display is just as vital, and there are many interface options available.

All displays work in a similar manner. In a very basic explanation, they all have many rows and columns of pixels driven by a controller that communicates with each pixel to emit the brightness and color needed to make up the transmitted image. In some devices, the pixels are diodes that light up when current flows (PMOLEDs and AMOLEDs), and in other electronics, the pixel acts as a shutter to let some of the light from a backlight visible. In all cases, a memory array stores the image information that travels to the display through an interface.

According to Wikipedia, "an interface is a shared boundary across which two separate components of a computer system exchange information. The exchange can be between software, computer hardware, peripheral devices, humans, and combinations of these. Some computer hardware devices such as a touchscreen can both send and receive data through the interface, while others such as a mouse or microphone may only provide an interface to send data to a given system.” In other words, an interface is something that facilitates communication between two objects. Although display interfaces serve a similar purpose, how that communication occurs varies widely.

Serial Peripheral Interface (SPI) is a synchronous serial communication interface best-suited for short distances. It was developed by Motorola for components to share data such as flash memory, sensors, Real-Time Clocks, analog-to-digital converters, and more. Because there is no protocol overhead, the transmission runs at relatively high speeds. SPI runs on one master (the side that generates the clock) with one or more slaves, usually the devices outside the central processor. One drawback of SPI is the number of pins required between devices. Each slave added to the master/slave system needs an additional chip select I/O pin on the master. SPI is a great option for small, low-resolution displays including PMOLEDs and smaller LCDs.

Philips Semiconductors invented I2C (Inter-integrated Circuit) or I-squared-C in 1982. It utilizes a multi-master, multi-slave, single-ended, serial computer bus system. Engineers developed I2C for simple peripherals on PCs, like keyboards and mice to then later apply it to displays. Like SPI, it only works for short distances within a device and uses an asynchronous serial port. What sets I2C apart from SPI is that it can support up to 1008 slaves and only requires two wires, serial clock (SCL), and serial data (SDA). Like SPI, I2C also works well with PMOLEDs and smaller LCDs. Many display systems transfer the touch sensor data through I2C.

RGB is used to interface with large color displays. It sends 8 bits of data for each of the three colors, Red Green, and Blue every clock cycle. Since there are 24 bits of data transmitted every clock cycle, at clock rates up to 50 MHz, this interface can drive much larger displays at video frame rates of 60Hz and up.

Low-Voltage Differential Signaling (LVDS) was developed in 1994 and is a popular choice for large LCDs and peripherals in need of high bandwidth, like high-definition graphics and fast frame rates. It is a great solution because of its high speed of data transmission while using low voltage. Two wires carry the signal,  with one wire carrying the exact inverse of its companion. The electric field generated by one wire is neatly concealed by the other, creating much less interference to nearby wireless systems. At the receiver end, a circuit reads the difference (hence the "differential" in the name) in voltage between the wires. As a result, this scheme doesn’t generate noise or gets its signals scrambled by external noise. The interface consists of four, six, or eight pairs of wires, plus a pair carrying the clock and some ground wires. 24-bit color information at the transmitter end is converted to serial information, transmitted quickly over these pairs of cables, then converted back to 24-bit parallel in the receiver, resulting in an interface that is very fast to handle large displays and is very immune to interference.

Mobile Industry Processor Interface (MIPI) is a newer technology that is managed by the MIPI Alliance and has become a popular choice among wearable and mobile developers. MIPI uses similar differential signaling to LVDS by using a clock pair and one to eight pairs of data called lanes. MIPI supports a complex protocol that allows high speed and low power modes, as well as the ability to read data back from the display at lower rates. There are several versions of MIPI for different applications, MIPI DSI being the one for displays.

Display components stretch the limitations of bandwidth. For perspective, the most common internet bandwidth in a residential home runs on average at around 20 megabits per second or 20 billion 1s and 0s per second. Even small displays can require 4MB per second, which is a lot of data in what is often a tightly constrained physical space.

Take the same PMOLED display with the 128 x 128 resolution and 16,384 separate diodes; it requires information as to when and how brightly to illuminate each pixel. For a display with only 16 shades, it takes 4 bits of data. 128 x 128 x 4 = 65,536 bits for one frame. Now multiply it by the 60Hz, and you get a bandwidth of 4 megabits/second for a small monochrome display.

The new family of Winstar TFT displays marked with “Bar“ has a typical elongated shape as we know it, for example, from character displays. This is an archive article published 12/20/2016. Some information may no longer be up to date and in line with the current state. Please contact us in case of interest.

Technologically, these are still “common” TFT displays with all their pros and cons, and the only essential difference is in its shape (form factor), as their sides ration isn´t 3:2 or so but approx. 2.5:1 to 4:1.

As we know, a comprehensive full-colour graphic display is not only a “trendy” thing but it can really display (and graphically differentiate) required content and if necessary, distinguish various alert messages by colour.

As can be seen, the 4.6“ display has the highest resolution and thus also the highest pixels density (DPI) from this series. That´s why WF46A is also suitable for applications with high demands on quality (fine details) of the displayed content (pictures, etc.). All three models have 24 bit RGB interface (40 pin FFC connector).

Relatively higher brightness (350-500 Cd/m2) contributes to a universal use. WF52A is available without a touch panel and also with a resistive or capacitive touch panel.

When we purchase a new smartphone we go through a list of specifications that includes the processor, software, cameras, display type, battery, etc. The display of the smartphone is something which has always been a concern for people. And smartphone technology has advanced so much in the past decade that you get several display technology options to choose from.

Today, a smartphone is not just a means to send and receive calls and texts. It has become a general necessity, so choosing the right technology should be your main priority. Coming back to displays, as we said there are plenty of display types available right now.

Two of the main contenders for display technologies that are widely available are AMOLED and LCD. Here in this article, we will be comprising AMOLED vs LCD and find out which one is better for you.

Starting with the AMOLED first, it is a part of the OLED display technology but with some more advanced features. To completely know about it must understand its all three components. The first one is LED, “Light Emitting Diode”. Then we have “O” which stands for organic and makes the OLED.

It actually means that organic material is placed with two conductors in each LED, which helps to produce the light. And the “AM” in AMOLED means Active Matrix, it has the capability to increase the quality of a pixel.

The AMOLED display is similar to the OLED in various factors like high brightness and sharpness, better battery life, colour reproduction, etc. AMOLED display also has a thin film transistor, “TFT” that is attached to each LED with a capacitor.

TFT helps to operate all the pixels in an AMOLED display. This display might have a lot of positives but there are a few negatives too let’s point both of them out.

It comes with individual LEDs so, the pixels can be turned on and off individually. This will show you true black colours, as the pixels on the black part of the image will be turned off.

A major issue with these displays is of burning of pixels. After showing a specific image or colour for a longer period of time, the pixel can get burned. And if there is a problem with a single pixel it will affect the entire display.

Low outdoor visibility, usually the AMOLED Displays are quote not bright in direct sunlight and outdoor readability could be a problem for some devices but average screen brightness.

The LCD stands for “Liquid Crystal Display”, and this display produces colours a lot differently than AMOLED. LCD display uses a dedicated backlight for the light source rather than using individual LED components.

The LCD displays function pretty simply, a series of thin films, transparent mirrors, and some white LED lights that distributes lights across the back of the display.

As we have mentioned, an LCD display always requires a backlight and also a colour filter. The backlight must have to pass through a thin film transistor matrix and a polarizer. So, when you see it, the whole screen will be lit and only a fraction of light gets through. This is the key difference comparing AMOLED vs LCD and this is what differentiates these two display technologies.

The LCD displays are cheaper compared to the AMOLED as there is only one source of light which makes it easier to produce. Most budget smartphones also use LCD displays.

LCD displays have bright whites, the backlight emits lots of light through pixels which makes it easy to read in outdoors. It also shows the “Accurate True to Life” colours, which means it has the colours that reflect the objects of the real world more accurately than others.

LCDs also offer the best viewing angle. Although it may depend on the smartphone you have. But most high-quality LCD displays support great viewing angles without any colour distortion or colour shifting.

The LCD displays can never show the deep blacks like AMOLED. Due to the single backlight, it always has to illuminate the screen making it impossible to show the deep blacks.

The LCDs are also thicker than other displays because of the backlight as it needs more volume. So, LCD smartphones are mostly thicker than AMOLED ones.

Both of these display technologies have their own Pros and Cons. Taking them aside everything ends up with the user preferences as people might have different preferences among different colours and contrast profiles. However, a few factors might help you to decide which one fits perfectly for you.

Let’s start with the pricing. Most AMOLED display smartphones always cost more than an LCD smartphone. Although the trend is changing a bit. But still, if you want to get a good quality AMOLED display you have to go for the flagship devices.

The colors are also very sharp and vibrant with the AMOLED displays. And they look much better than any LCD display. The brightness is something where LCDs stood ahead of the AMOLED display. So using an LCD display outdoors gives much better results.

The last thing is battery consumption, and there is no one near the AMOLED displays in terms of battery. As of now, all smartphones feature a Dark Mode and most of the apps and UI are dark black with a black background. This dark UI on smartphones doesn’t require any other light, it gives the AMOLED displays a boost in battery performance.

Looking at all these factors and comparing AMOLED vs LCD displays, the AMOLED displays are certainly better than the LCDs. Also, the big display OEMs, like Samsung and LG are focusing more the OLED technologies for their future projects. So, it makes sense to look out for AMOLED displays. That being said, if we see further enhancements in the LCD technology in terms of battery efficiency and more, there is no point to cancel them at this moment.

Thin-Film Transistor Liquid Crystal Displays use thin-film transistors to control the voltage applied to the liquid crystal layer at a sub-pixel level. The structure of TFT LCDs consists of a TFT “sandwich” and a BLU (Backlight Unit). A typical configuration is shown in the schematic diagram below.

Firstly, between the back and front polarizers, TFT LCD cells are made with two glass substrates – one for color filters, the other for a TFT array – and a liquid crystal layer sandwiched in between.

Secondly, BLU (Backlight Unit) usually consists of three components: BEF (Brightness Enhancement Film), DBEF (Dual Brightness Enhancement Film), and LGP (Light Guide Plate).

For normally black TFT LCDs, if we follow along a piece of light setting off from its backlight source, it will bea)guided uniformly by LGP;b)reflected and enhanced by BEF and DBEF;c)polarized by the back polarizer;d)polarization changed by twisted LC under the voltage applied by TFT arrays;e)“tinted” red/green/blue by corresponding color filter of the subpixel;f)let through the front polarizer by matched polarization; andg)finally, it will reach the surface and appears in viewer’s eyes.

For normally white panels, processd)will be the opposite – known as the polarization rotation effect, light is twisted in a voltage-off stage and can pass through the front polarizer by default, thus displaying white normally. However, when the voltage applied increases, this polarization rotation effect would be gradually diminished. And the light would not be able to pass through the front polarizer anymore without changing its polarization. In this way, certain pixels will appear in different colors.

Normally black LCDs have higher contrast and wider viewing angles without grayscale inversion phenomenon compared to their normally white relatives. And whether TFT LCDs are normally black or white depends on their LC switching mode:
