Two types of screens materials: LCD and OLED.
- TFT: Thin Film Transistor is a kind of active-matrix LCD (AM-LCD).
- SLCD: Splice Liquid Crystal Display.
- IPS: In-Plane Switching.
- PMOLED: Passive-matrix Organic Light Emitting Diode.
- AMOLED: Active-matrix Organic Light Emitting Diode.
- Super AMOLED
There are several display types of screens in mobile phones and smart bands. In terms of material, the screen can be divided into the LCD and OLED.
LCD: that is, Liquid Crystal Display.
Because of its low power consumption, low cost, and excellent image quality, it is the most prevalent form of screen among mobile phones. They are usually simple to read, even under direct sunlight, with backlight.
Some LCD kinds include TFT, IPS, SLCD, UFB, SNT, NOVA, and so on. They do not depict various screen materials, but LCD’s different display technology. The most popular technique for LCD is viewed as follows:
TFT: Thin Film Transistor is a kind of active-matrix LCD (AM-LCD).
This implies that a different transistor is situated at the back of the screen, enabling the display to regulate each pixel separately. This guarantees a quicker reaction time. TFT is the most popular display technology with high brightness, high contrast, elevated graphic layers, and vivid picture. It also consumes more energy, however, and is more costly. Motorola is the TFT screen’s representative.
SLCD: Splice Liquid Crystal Display.
SLCD is an integrated splice display unit. It can not only be used as a display individually but also splice into a large screen. It is a high-end source of LCD, featuring warmer color, properer brightest of human to watch.
IPS: In-Plane Switching.
IPS is generally known as “Super TFT.” As introduced, it is just a variant of the TFT screen. It is a kind of TFT screen mostly, but only a TFT screen adopting IPS technology, that is, the liquid crystals are aligned horizontally to the screen somewhat of vertically. The advantages of IPS screen technology is the wider viewing angle, accurate color reproduction, less fluid when touching, energy-saving, and environmental protection. iPhone4 is the representative of the IPS screen.
OLED: Organic Light-emitting Diode.
OLED is constructed from organic light-emitting materials that transmit light when electricity is applied. OLED displays are emissive – and do not require any backlight or filtering systems that are used in LCDs. As a result, OLED is thinner, lighter, brighter, need less power, have better viewing angles, contrast, and response time for video and animation. OLED is also cheaper and easier to manufacture.
Now, there are two types of OLED displays – PMOLED and AMOLED. The difference is in the driving electronics – it can be either Passive Matrix (PM) or Active Matrix (AM).
PMOLED: Passive-matrix Organic Light Emitting Diode.
A PMOLED display uses a simple control system in which you control each row (or line) in the display sequence (one at a time). PMOLED electronics do not contain a storage capacitor, and so the pixels in each line are actually off most of the time. To recompense for this, you need to use more voltage to make them brighter. PMOLED displays are also limited in resolution and size. They are usually small and are used to display character data or small icons: they are being used in MP3 players, mobile phone sub displays, etc.
AMOLED: Active-matrix Organic Light Emitting Diode.
AMOLED is a display technology generally used in mobile phones, laptops, and televisions. Its response time is quicker than IPS, and the image quality is more immeasurable than all the above ones. It can display clear in outside light, just lightly inferior to the NOVA. In general, AMOLED is featured with emissive, less power consumption, wide viewing angle, high contrast, and quicker response rate. AMOLED displays may be difficult to view in direct sunlight compared with LCDs because of their reduced maximum brightness.
An AMOLED is inspired by a TFT which contains a storage capacitor that manages the line pixel states, and so enables large size and large resolution displays. AMOLED can be made much more inclusive than PMOLED and have no restriction on size or resolution.
AMOLED is generally used in Samsung mobiles, but in fact, it is not the exclusive technology of Samsung.
Super AMOLED, in one hand, is more susceptible than AMOLED in operation, the screen can be viewed clearly under the sun, even at any angle. However, its disadvantage is also apparent. The biggest downside is poor color reproduction and unnatural bright tone.
