The Construction about TFT LCD Display

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 128x64 lcd display 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 Modules 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.Transistors take up only a small fraction of the area of each pixel and the rest of the silicon film is etched away to allow light to easily pass through it.
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.

Application of TFT LCD Display

A thin-film-transistor liquid-crystal display (TFT LCD) is a variant of a liquid-crystal display (LCD) that uses thin-film transistor (TFT) technology to improve image qualities such as addressability and contrast. A TFT LCD is an active-matrix LCD, in contrast to passive-matrix LCDs or simple, direct-driven LCDs with a few segments.
TFT Lcd Modules are used in appliances including television sets, computer monitors, mobile phones, handheld video game systems, personal digital assistants, navigation systems and projectors.TFT LCDs are also used in car instrument clusters because display lcd 20x4 allow the driver to customize the cluster, as well as being able to provide an analogue-like display with digital elements.

How does OLED work?

There are additional flavors of 320x240 lcd display that are better for different kinds of devices. When a device only needs to display a static pattern with relatively slow refreshes—like the 240x64 lcd readout of a calculator or e-ink displays of the Kindle Paperwhite—you can use something called a passive matrix OLED (or a PMOLED). These work by turning on voltage to specific areas of the film and leaving them on until the device refreshes its instructions.Then there's active matrix OLEDs, like the AMOLEDs you might find in a smart phone. These are for high-definition applications that demand fast refresh rates, such as smartphone screens or HD televisions. AMOLED displays require a thin film transistor back-plane to actually drive each of the individual pixels, but this layer is just as flexible as the others, allowing for the development of rollable, foldable, transparent display panel prototypes.

What is OLED Display?

OLED, or Organic Light Emitting Diodes, are an offshoot of existing conventional LED technology.OLED modules are semiconducting light sources that function through electroluminescence—that is, they produce photons (aka light) by plopping electrons into little electron holes within the device's emissive layer. Basically, electricity goes in and light comes out thanks to a semiconductuctive material, rather than a white-hot metal filament like an old-school lightbulb.
The technology of 240x128 lcd module, first successfully implemented in 1987 by Kodak researchers Ching W. Tang and Steven Van Slyke, takes this same idea as LED, but flattens it. Rather than an array of individual LED bulbs, OLED uses a series of thin, light emitting films. This allows the OLED array to produce brighter light while using less energy than existing LCD/LED technologies. And since these light-emitting films are composed of hydrocarbon chains, rather than semiconductors laden with heavy metals like gallium arsenide phosphide, they get that "O" for "organic" in their name.

An OLED panel is typically composed of four primary layers: The substrate, which acts as the structural framework; the anode, which draws electrons; the cathode, which provides electrons; and the organic layer between. That organic layer is further divided into a conducting layer—which provides the "electron holes" that the electrons flowing through layer can snap into, shedding energy in the process—and an emissive layer where the light is actually produced. And if you want to start messing with producing actual color, it's just a matter of adding red-, green-, and blue-tinted plastic layers to the substrate.

why designers in these areas should strongly consider using OLED Display

LCDs are often supplied as lcd modules which have built-in driver circuitry that simplifies installation and improves reliability. However, the addition of packaged driver circuitry in OLED Module also results in a number of
disadvantages because it:
 • Increases the thickness of the display
 • Raises the costs
 • Creates greater vulnerability for failures of the modules
All of these drawbacks are important considerations when it comes to displays for industrial, automotive and portable equipment. Chip-on-Glass (COG) LCD modules offer a very thin profile, enhanced reliability, and a reasonable price.

Differences between OLED, LED, LCD, and TFT Screens

LCD display: liquid crystal display. Works by adjusting the amount of light blocked. Usually has a backlight but might not . The green-black ones can be very cheap and are a mature technology. Response time can be slow.
TFT LCD displays :is a type of LCD with a thin film transistor attached to each pixel. All computer LCD screens are TFT since early 2000s; older ones had slower response times and poorer colour. Cost is now very good; power consumption is fairly good but dominated by the backlight. Has to be manufactured out of glass.
LED display: light emitting diode. As the name suggests, emits light rather than blocking it like LCD. Used for red/green/blue/white indicator lights everywhere. Some manufacturers advertise "LED" displays that are TFT screens with a white LED backlight, which is just confusing. Ones that are real LED screens are usually OLED.
OLED Display: organic LED (rather than silicon or germanium based like regular LEDs). Comparatively recent technology, so cost still quite variable and not available in really large sizes. In theory can be printed on plastic, resulting in lighter flexible displays with good brightness, good power consumption and good response time.

Tsingtek character oleds have the potential to be cost effective

Tsingtek character oleds have the potential to be cost effective. They have fewer processing steps and are also less materials and equipment intensive than today’s LCDs. As OLED/lcd module manufacturer technologies mature, OLED production yields should continue to improve and larger-scale equipment be brought on line. As a result, production costs will continue to decrease - ultimately enabling OLEDs to outperform LCDs on a cost basis. With so many exciting product capabilities, it’s not surprising that leading market analysts, project that the OLED market will grow rapidly over the next few years. OLED products including a variety of small-area displays for mobile phones and other consumer electronics applications and the introduction of notebook PCs and OLED TVs during the period.

Tsingtek OLED DISPLAYS Superiority

Compared to LCDs, today’s dominant flat panel display technology,Tsingtek OLEDs are capable of providing markedly better performance features. Thinner, lighter and more attractive, OLEDs offer much faster response times, wider viewing angles, higher contrast ratios and brighter, more saturated colors - for a more enjoyable viewing experience. With operating lifetimes now in the tens of thousands of hours, serial oled can also be more energy efficient than LCDs.

How does an ordinary LED/lcd module work?

Before you can understand OLEDs, it helps if you understand how a conventional LED/lcd module works. Take two slabs of semiconductor material (something like silicon or germanium), one slightly rich in electrons (called n-type) and one slightly poor in electrons (if you prefer, that's the same as saying it's rich in "holes" where electrons should be, which is called p-type). Join the n-type and p-type slabs together and, where they meet, you get a kind of neutral, no-man's land forming at the junction where surplus electrons and holes cross over and cancel one another out. Now connect electrical contacts to the two slabs and switch on the power. If you wire the contacts one way, electrons flow across the junction from the rich side to the poor, while holes flow the other way, and a current flows across the junction and through your circuit.

OLED vs LCD

OLED displays have the following advantages over LCD displays:
1.Lower power consumption
2.Faster refresh rate and better contrast
3.Greater brightness - The screens are brighter, and have a fuller viewing angle
4.Exciting displays - new types of displays, that we do not have today, like ultra-thin, flexible or transparent displays
5.Better durability - OLEDs are very durable and can operate in a broader temperature range
6.Lighter weight - the screen can be made very thin, and can even be 'printed' on flexible surfaces

OLED disadvantages

OLEDs aren't perfect. First of all, today it costs more to produce an OLED Display Module than it does to produce an LCD - although this should hopefully change in the future, as OLEDs has a potential to be even cheaper than LCDs because of their simple design. OLEDs have limited lifetime (like any display, really), that was quite a problem a few years ago. But there has been constant progress, and today this is almost a non-issue. Today OLEDs last long enough to be used in mobile devices and TVs. OLEDs can also be problematic in direct sunlight, because of their emmissive nature. But companies are working to make it better, and newer AMOLEDs are quite good in that respect - some even consider them superior to LCDs.

COG LCD Display is different Serial Lcd Display

Serial Lcd Display Module are Character LCD Modules with integrated RS232, I2C and SPI serial interfaces with a broad range of industry standard sizes in 2x16, 2x20, and 4x20 modules.COG (Chip-On-Glass) displays are monochromatic passive or active matrix LCD displays that can display information as text or in a dot matrix pattern.
