TFT LCD display with touchscreen capabilities allow for more streamlined operations. It is being used in more and more areas. There arefive types of touchscreen technologies, offering benefits and limitations, namely in the areas of cost, picture quality, touch sensitivity and durability.

Touch type - TFT touchscreens discussed earlier have distinct advantages and disadvantages. Choice is hence a compromise, by weighing pros against cons. Projected capacitive touch is ideal for harsh, industrial and outdoor applications. IR type will not be a good fit for such applications. However, if clarity if important, then IR type touchscreen will be a good selection.

Accuracy of touch - This is the capability of providing reliable touch performance in devices when the TFT touchscreen is subjected to surrounding electric or magnetic noise. User must be able to correctly select target on screen without accidentally touch adjacent object.

Touchscreen resolution - Here we refer to the number of active touch-point and simultaneous touch-point supported by TFT touchscreen. This affects pointing precision and selection errors. A higher resolution screen provides additional touch-points and greater pointing.

Response time - The shorter time a TFT touchscreen responds to a touch, the better user would feel about the touchscreen. Research shows that humans need less than 10ms to feel comfortable a touch response. SAW touchscreen has the shortest response time, about 10ms. Whereas IR has a higher response time of around 20ms.

Clarity- Touchscreens are normally attached on top of the TFT LCD. So there is loss of light and affect clarity of image. IR touchscreen has no overlay, hence its transmission is 95% ~ 100%, clarity is the best among all the touchscreen solutions. Resistive type has the lowest rating in this area.

Environment- Selection of TFT touchscreen is also based on the product"s deployment environment. If the TFT touchscreen working environment is in outdoor and harsh conditions, then the selection should be focused on the type that can withstand dust, temperature, moisture, etc.

Life expectancy - In an actively used situation, TFT touchscreen"s degradation in performance is expected. Longevity of IR touchscreen is about five years, capacitive type has a shorter life of around two years.

Our TFT color displays with 2.0" / 2.8" / 3.5" are the further development of the widespread black&white graphic displays: simply connected via SPI interface and therefore suitable for all μC. Alternatively, these small TFTs can also be connected via the classic RGB interface or an 8- or 16-bit data bus.

TFT is an abbreviation for Thin Film Transistor, a flat panel display used to improve the operation and utility of LCD screens. In order to portray an appearance to the audience, a liquid crystal display (LCD) utilizes a crystalline-filled fluid to modify rear lighting polarized origin through the use of an electromagnetic force among two relatively thin metal wires such as indium oxide (ITO). However, color TFT displays are associated with this method, which can be employed in both divided and pixelated display systems.

With motion pictures displayed on an LCD, the intrinsic sluggish rate of increase between liquid phases over a significant number of pixel components can be an issue due to capacitance impacts, which can create a blurring of the visuals. Placing a high-velocity LCD control device inside the formation of a thin-film transistor immediately next to the cell component just on a glass screen, the issue of LCD picture speed may be substantially improved, and image blur can be eliminated for all useful purposes entirely.

Organic light-emitting diodes (AMOLEDs) are a type of flat light-emitting advanced technologies that are created by interspersing a succession of organic thin sheets over two conducting conductors. An electrical charge causes a brilliant light to be produced when the current flows. AMOLED displays are light-emitting screens that do not require a backlight, making them thinner and more energy-efficient than liquid crystal displays (LCDs) (which will need a white backlight).

Half-Life has been expanded. TFT displays have a far longer half-life than its LED equivalents, and they are available in a number of sizes, which might have an effect on the device"s half-life based on the phone"s usage as well as other variables. Touch panels for TFT screens can be either resistant or capacitance in nature.

Backlighting is unnecessary for AMOLEDs. LCDs produce images by selectively blocking parts of the illumination, whereas AMOLEDs produce light. AMOLEDs utilize less energy than LCDs since they don"t need backlighting. This is critical for battery-powered devices such as phones.

While AMOLED light-emitting sheets are lightweight, the substrate can also be elastic rather than stiff. AMOLED films are not limited to glass-like LEDs and LCDs.

AMOLEDs offer 170-degree ranges of vision. LCDs operate by obscuring the light. Hence they have intrinsic viewing obstacles. In addition, AMOLEDs have a substantially wider viewing spectrum.

AMOLEDs outperform LEDs. Since AMOLED organic coatings are less than LED inorganic crystal levels, AMOLED conducting and particle emitters layers can just be multi-layered. Also, LEDs and LCDs need glass backing, which absorbs light. AMOLEDs don"t need it.

While red and green AMOLED sheets have a greater lifespan (46,000 to 230,000 hours), azure compounds have significantly shorter longevity (up to roughly 14,000 hours).

Due to the fact that AMOLED displays inherently emit illumination, they do not need a backlight when used on a monitor screen. Conversely, LCDs require backlights since the liquid crystals themselves are incapable of producing light under their own. Direct light emission from AMOLED displays also allows for the developing of lightweight display devices than others using TFT LCDs.

LCD displays have a higher brightness than AMOLED panels. This is owing to the LCD"s usage of led backlight, which may provide a brilliant illumination of the entire display. Despite the fact that AMOLEDs produce high levels of brilliance from their illumination, they will never be able to match the intensity of LCD lighting.

LCD screens use less power than AMOLED displays, which provides a slight advantage. The amount of energy consumed by AMOLED displays is dependent on the intensity of the screen. Lowered luminance results in lower energy usage, however, it might not be the best solution because the contrast would suffer as a result of the decreased brightness. In some situations, such as when to use an AMOLED device in direct sunlight, it is not an optimal situation.

However, the backlit keys of TFT displays account for the majority of their power usage. TFT screens" efficiency is considerably improved when the backlight is set to a lesser brightness level than the default setting. For example, replacing the light of an LCD TV with just an Led flash will have no effect on the image quality, but will result in lower power usage than replacing the light of an AMOLED TV.

With the exception of phones, numerous other technologies make use of displays to allow customers to engage in direct communication with them. To determine whether or not TFT LCD will be able to withstand the development of AMOLED innovation, we should first review the benefits of LCD technology. The backlighting quality ensures that whites are strong and brightness is superb but will deplete a battery much more quickly than just an AMOLED display. Furthermore, the cost of LCD screens is a considerable consideration. In addition to being less expensive and more easily accessible, they are produced in standard industry sizes, allowing them to be purchased for innovative products with relative ease.

TFT displays are also known as an “Active Matrix TFT LCD module” and have an array of thin film transistors fabricated on the glass that makes the LCD. There is one of these transistors for each pixel on the LCD.

LCDs use voltage applied to a field of microscopic liquid crystals to change the crystal’s orientation, which in turn changes the polarization of the liquid crystal which creates light or dark pixels on the display.

Beautiful, complex images: All of our TFT modules are full-color graphic displays. Unlike standard monochrome character displays, you can create complex images for an imaginative user experience.

Single Supply: Most of the TFTs use an integrated controller with built-in voltage generation so only a single 3.3v supply is needed for both the panel power and logic voltage.

Many of our character LCD modules use a standard HD44780 controller, so they can be quickly integrated into a new product or used as a replacement in your existing products.

Many of the LCD controllers on board our graphic LCD display modules also include a CGROM (character generator ROM) which allows for easy character information as well as full bit-mapped graphic information to be shown.

Some of the graphic LCD displays have the ability to render graphics in grayscale, enabling you to show images and elements of your UI (user interface) with more depth and definition.

In market, LCD means passive matrix LCDs which increase TN (Twisted Nematic), STN (Super Twisted Nematic), or FSTN (Film Compensated STN) LCD Displays. It is a kind of earliest and lowest cost display technology.

LCD screens are still found in the market of low cost watches, calculators, clocks, utility meters etc. because of its advantages of low cost, fast response time (speed), wide temperature range,  low power consumption, sunlight readable with transflective or reflective polarizers etc.  Most of them are monochrome LCD display and belong to passive-matrix LCDs.

TFT LCDs have capacitors and transistors. These are the two elements that play a key part in ensuring that the TFT display monitor functions by using a very small amount of energy without running out of operation.

Normally, we say TFT LCD panels or TFT screens, we mean they are TN (Twisted Nematic) Type TFT displays or TN panels, or TN screen technology. TFT is active-matrix LCDs, it is a kind of LCD technologies.

TFT has wider viewing angles, better contrast ratio than TN displays. TFT display technologies have been widely used for computer monitors, laptops, medical monitors, industrial monitors, ATM, point of sales etc.

Actually, IPS technology is a kind of TFT display with thin film transistors for individual pixels. But IPS displays have superior high contrast, wide viewing angle, color reproduction, image quality etc. IPS screens have been found in high-end applications, like Apple iPhones, iPads, Samsung mobile phones, more expensive LCD monitors etc.

Both TFT LCD displays and IPS LCD displays are active matrix displays, neither of them can produce color, there is a layer of RGB (red, green, blue) color filter in each LCD pixels to make LCD showing colors. If you use a magnifier to see your monitor, you will see RGB color. With switch on/off and different level of brightness RGB, we can get many colors.

Neither of them can’t release color themselves, they have relied on extra light source in order to display. LED backlights are usually be together with them in the display modules as the light sources. Besides, both TFT screens and IPS screens are transmissive, it will need more power or more expensive than passive matrix LCD screens to be seen under sunlight.  IPS screens transmittance is lower than TFT screens, more power is needed for IPS LCD display.

An AMOLED display consists of an active matrix of OLED pixels generating light (luminescence) upon electrical activation that have been deposited or integrated onto a thin-film transistor (TFT) array, which functions as a series of switches to control the current flowing to each individual pixel.

Typically, this continuous current flow is controlled by at least two TFTs at each pixel (to trigger the luminescence), with one TFT to start and stop the charging of a storage capacitor and the second to provide a voltage source at the level needed to create a constant current to the pixel, thereby eliminating the need for the very high currents required for PMOLED.

TFT backplane technology is crucial in the fabrication of AMOLED displays. In AMOLEDs, the two primary TFT backplane technologies, polycrystalline silicon (poly-Si) and amorphous silicon (a-Si), are currently used offering the potential for directly fabricating the active-matrix backplanes at low temperatures (below 150 °C) onto flexible plastic substrates for producing flexible AMOLED displays. Brightness of AMOLED is determined by the strength of the electron current. The colors are controlled by the red, green and blue light emitting diodes.  It is easier to understand by thinking of each pixel is independently colored, mini-LED.

IPS technology is like an improvement on the traditional TFT LCD display module in the sense that it has the same basic structure, but with more enhanced features and more widespread usability compared with the older generation of TN type TFT screen (normally used for low-cost computer monitors). Actually, it is called super TFT.  IPS LCD display consists of the following high-end features. It has much wider viewing angles, more consistent, better color in all viewing directions, it has higher contrast, faster response time. But IPS screens are not perfect as their higher manufacturing cost compared with TN TFT LCD.

Utilizing an electrical charge that causes the liquid crystal material to change their molecular structure allowing various wavelengths of backlight to “pass-through”. The active matrix of the TFT display is in constant flux and changes or refreshes rapidly depending upon the incoming signal from the control device.

This is a high image quality monitor featuring the wide LCD (12.3” with pixel count of 1,920×720) combining high performance of color reproduction (NTSC ratio: 100%), high contrast ratio (1000:1) and high brightness (1000cd/m2) and is also most suitable for the next generation CIDs, cluster and digital mirrors.

A: There are basically two approches to increase a display"s sunlight readability: increase the brightness level of the display, or reduce the ambient light reflection on the display surface. Good Display has several technology for outdoor readable applications, such as high brightness panel, transflective panel, anti-reflection and antiglare surface treatment, for more information, please check Outdoor Use TFT Displays for more information.

A: Yes. Good Display TFT LCDs response time is between 16ms to 25ms. Most of our newly developed LCD panels have 16ms response time, which is enough for moving picture. Please check the individual display specification for detail information.

A: LCD displays typically feature a wider viewing angle from straight on or above, compared to the viewing angle from below. The reverse-scan feature enables customers to select either a normal scan or reverse scan to obtain the best intended image, depending on whether the mounted display will be viewed typically from above or below. Good Display TFT LCDs have reverse scan function.

A: The defination of the CCFL lifetime is when the brightness level droped to 50% of its initial full brightness level. All the CCFL backlights for TFT LCDs are rated at 50,000 hours minimum. But most of the CCFL lamp unit can be replaced easily.

A: For industrial grade LED backlits TFT-LCD, the minimum lifetime is 60K hours. Be sure to consult the individual part specification for information on a specific LCM.

A: Many of the Good Display TFT LCDs operate at both 3.3 and 5V. However, as the 3.3V becomes the new standard, the LSI manufactory might decide to only support 3.3V, that is not controlled by Good Display. Please check the individual part specification for information.

FlexEnable’s glass-free organic LCD (OLCD) delivers high-brightness, long lifetime flexible displays that are low cost and scalable to large areas, while also being thin, lightweight and shatterproof.

OLCD is a plastic display technology with full colour and video-rate capability. It enables product companies to create striking designs and realise novel use cases by merging the display into the product design rather than accommodating it by the design.

Unlike flexible OLED displays, which are predominantly adopted in flagship smartphones and smartwatches, OLCD opens up the use of flexible displays to a wider range of mass-market applications. It has several attributes that make it better suited than flexible OLED to applications across large-area consumer electronics, smart home appliances, automotive, notebooks and tablets, and digital signage.

OLCD can be conformed and wrapped around surfaces and cut into non-rectangular shapes during the production process. Holes can be also added to fit around the functional design of the system – for example around knobs and switches.

As with glass-based LCD, the lifetime of OLCD is independent of the display brightness, because it is achieved through transmission of a separate light source (the backlight), rather than emission of its own light. For example OLCD can be made ultra-bright for viewing in daylight conditions without affecting the display lifetime – an important requirement for vehicle surface-integrated displays.

OLCD is the lowest cost flexible display technology – it is three to four times lower cost that flexible OLED today. This is because it makes use of existing display factories and supply chain and deploys a low temperature process that results in low manufacturing costs and high yield.

Unlike other flexible display approaches, OLCD is naturally scalable to large sizes. It can be made as small or as large as the manufacturing equipment used for flat panel displays allows.

The flexibility of OLCD allows an ultra-narrow bezel to be implemented by folding down the borders behind the display. This brings huge value in applications like notebooks and tablets where borderless means bigger displays for the same sized device. The bezel size allowed by OLCD is independent of the display size or resolution. In addition, OLCD can make a notebook up to 100g lighter and 0.5mm thinner.

OLCD is the key to the fabrication of ultra-high contrast dual cell displays with true pixel level dimming, offering OLED-like performance at a fraction of the cost. The extremely thin OLCD substrate brings advantages in cost, viewing angle and module thickness compared to glass displays. At the same time OLCD retains the flexibility required for applications such as surface-integrated automotive displays.

Due to its unique properties, OLCD has the potential to transform how and where displays are used in products. The videos below give a glimpse into this innovative technology.

OLCD brings the benefits of being thin, light, shatterproof and conformable, while offering the same quality and performance as traditional glass LCDs. The mechanical advantages of plastic OLCD over glass LCD are further enhanced by the technology’s excellent optical performance, much of which originates from the extreme thinness of plastic TAC substrates compared to glass.
