What is TFT-LCD technology?
The Thin film transistor liquid crystal display (TFT LCD) technology is the most common display technology used in mobile phones. A variant of liquid crystal display (LCD), the technology uses TFT technology to enhance image quality. It offers better image quality and higher resolutions as compared to earlier generation LCD displays. It ranges from the budget smartphones like the HTC Desire C to high-end tablets, like the Google Nexus 7.However TFT screens consume lot energy, which results in poor battery life.
Since this display technology is cheaper to manufacture, these are most commonly found on budget phones, feature phones and low-end smart phones.
IPS LCD or Plane Switching liquid Crystal Display
IPS LCD Stands for In Plane Switching liquid Crystal Display. This technology offers better display quality as compared to the TFT-LCD display. The good part about IPS LCD is that it offers better viewing angles and consumes less power. Due to higher costs, it is found only on high-end smartphones. Apple uses a high resolution (640x960 pixels) version of IPS LCD in its iPhone 4, which is also called Retina Display.OLED Display is better
Organic Light-Emitting Diode (OLED) display technology is much better as compared to the LCD display technology because of its excellent color reproduction, faster response times, wider viewing angles, higher brightness and extremely lightweight designs. OLEDs are solid-state devices composed of thin films of organic molecules that create light with the application of electricity.The plastic, organic layers of an OLED are thinner, lighter and more flexible than the crystalline layers in an LED or LCD. OLEDs are brighter than LEDs and do not require backlighting like LCDs. Since OLEDs do not require backlighting, they consume much less power than LCDs.
Since these display forms are easier to produce, they can be made to larger sizes. Because OLEDs are essentially plastics, they can be made into large, thin sheets.
AMOLED Display
AMOLED stands for Active Matrix Organic Light Emitting Diode. A step ahead of OLED screens, the AMOLED screens can control each pixel individuality while maintaining the properties of an OLED panel. AMOLED screens use a different sub pixel arrangement which can reduce the image quality a bit.AMOLED screens have all the attributes of an OLED display like excellent colour reproduction, faster response times, wider viewing angles, higher brightness and extremely lightweight designs. This is the preferred technology of smartphone manufacturers although they are quite expensive to produce. Opt for AMOLED display over TFT LCD.
Super AMOLED display technology
Super AMOLED display technology is an advanced version of AMOLED display. Samsung uses this term for the AMOLED panels that they develop. Super AMOLED screens are built with capacitive touch sensors on the display itself. Super AMOLED display is much more responsive than an AMOLED display. Samsung top-of-the-line Galaxy SII comes engineered with Super AMOLED display technology. Samsung has already took it's SMOLED screen to next levels by developing Super AMOLED+, HD Super AMOLED+ and FHD Super AMOLED+ screens.All you need to know about Retina Display
It is a name given by Apple to the high-resolution screen technology introduced on the iPhone 4 in June 2010. Something is a Retina Display when it offers a density of pixels above 163 pixels per inch. The company calls it the Retina display because its pixels cannot be individually identified by a human eye, thus rendering a super sharp display, more crisp text and more clear pictures.Retina Display is designed to smooth the jagged edges of pixels are provide a higher-quality image than previously available on mobile devices. Apple claims that its resolution is so good that it makes it impossible for the human eye to distinguish individual pixels. Its effects show up in text, images and videos.
- a) In general, the retain displays offers these benefits:
- b) A greater pixel density
- c) Higher contrast ratio than earlier models for brighter whites and deeper blacks
- d) In-Plane Switching (IPS) technology to improve viewing angles
- e) Chemically treated glass over the screen and LED backlighting to improve the quality of the image
- f) Color Boost display
