Phone Screens in

Home Articles Which display is better for a smartphone: AMOLED or IPS? When choosing a smartphone, perhaps the first thing we pay attention to is the screen. We need a clear and bright picture, fast response and economical power consumption. These characteristics largely depend on what type of matrix is ​​used in the gadget. The editors of ZOOM.CNews figured out how smartphone displays differ and what are the pros and cons of different matrices. WHICH DISPLAY FOR A SMARTPHONE IS BETTER: AMOLED OR IPS? There are a lot of different types of matrices, but there are two current technologies for the production of screens for smartphones - LCD and OLED. All other options are their varieties and marketing names. LCD (Liquid Crystal Display) technology uses liquid silicon crystals, OLED (Organic Light-Emitting Diode) technology uses organic light emitting diodes. Initially, both LCD and OLED matrices were passive, but such di  Phone Screens in splays quickly consumed battery power. To solve the problem, TFT (Thin film transistor) was added to the matrices - thin-film transistors that control the operation of crystals or diodes. This is how active matrices appeared: IPS is based on LCD, and AMOLED is a kind of OLED. Of the LCD matrices in smartphones, IPS and LTPS are now used - an improved version of IPS using low-temperature polycrystalline silicon. Screens on LTPS respond to clicks almost twice as fast as IPS and consume less power, but also cost more. Active matrix AMOLEDs also have several marketing names: Super AMOLED, Super AMOLED Plus, and Dynamic AMOLED. They differ slightly in color accuracy and image clarity, but are based on the same technology. And in smartphones with a curved display, P-OLED is used: the same OLED matrix, but with a plastic substrate that allows you to bend the screen. Samsung Galaxy Fold with curved OLED screen The Retina screens that Apple uses stand out. However, this is not a separate type of matrix, but the name of displays with an increased pixel density per inch. At the same time, both technologies can be hidden under the name Retina: before the advent of the iPhone X, it was only IPS, but now Apple's flagships with Retina display are equipped with AMOLED matrices. As for new technologies - Mini LED, microLED, QLED - their mass production has not yet been established. In particular, Mini LEDs are cheaper than OLEDs, but they've only appeared on Apple's top-end tablets so far. MicroLED displays are too expensive for smartphones. And QLED matrices are still used only in TVs, since it is difficult to achieve the desired density of quantum dots in small screens. LCD uses the principle of light polarization: under the influence of current, particles in liquid crystals turn and transmit light waves with a given polarization axis, as a result, subpixels are painted in one of the primary colors of the spectrum (red, green, blue). Initially, the TN film (Twisted Nematic) LCD matrix used twisted crystals that rotated in a spiral. In the newer IPS (In-Plane Switching), the crystals rotate in the same plane, which ensures high image quality.

Compared to bright OLED displays, LCDs tend to have more subdued colors due to the air gap between the touchscreen and the matrix, which reduces brightness and saturation. But many users find LCD colors to be more natural, so it's a matter of preference. https://tonaton.ug/s_11-touch-screen-digitizers
