Companies bring their smartphones with different displays according to the budget. Smartphones of similar and different budgets equipped with different displays are available in the market. Instead of getting confused, today let’s talk about the types of displays. So that you can have better information about the display and the priority of the display before buying a smartphone…
TFT LCD
Thin film transistor technology was commonly used in LCD mobile phones. TFT LCDs provide decent image quality and high resolution. Their viewing angles are not that good. Also, they are not visible clearly in direct sunlight. Also, larger TFT displays consume more power and are not battery-friendly. But these are cheap options, due to which companies like to offer them in budget phones. These are widely used in feature phones and low cost smartphones.
IPS-LCD
IPS stands for In-Place Switching. Common IPS LCDs are considered better than TFT. You look at this display from any angle, everything will be clearly visible. That means viewing angles are better in these. Another specialty is that IPS-LCD displays reduce battery consumption. Due to their presence in the mobile, battery life increases. Obviously these displays are more expensive than TFT LCD. Apart from this, colors appear more accurate in these. At the same time, colors are not as punchy compared to AMOLED screens. This is the reason why companies generally give them priority only in expensive smartphones.
OLED (Organic Light Emitting Diode)
OLED stands for Organic Light Emitting Diode. This is a new technology which is being used in mobiles and monitors nowadays. In this, technically carbon based organic material is filled between 2 conducting sheets (cathode and anode). Then it is closed from both sides. When an electric pulse is applied between these two sheets, light is produced from the conductor filled in between. The brightness and contrast of a display depend on the electric pulse. If we compare OLED with LCD, it is much better than them. Be it any aspect like color, response or brightness.
amoled
AMOLED stands for Active Matrix Organic Light Emitting Diode. This is also a type of OLED display whose trend has gained momentum. This is also given in expensive phones. Like OLED, it is also a high quality display, which has attractive features like better color coordination, light weight, battery friendly. The most important feature of this display is that its blacks are deep. In linguistic terms, black color appears to be completely black. Apart from this the colors are quite punchy.
Super AMOLED
Recently Samsung A6, J6 Like this display is used in smartphones. Actually, it is an advanced version of AMOLED, which has been prepared by Samsung by the name of ‘Super AMOLED’. Actually, this is the version of OLED display made by Samsung. However, some experts believe that Super AMOLED has more punchy colors than AMOLED.
The display in any smartphone is the touchscreen. And there are two types of touchscreens.
Capacitive Touchscreen
Capacitive touchscreen technology consists of a glass layer coated with a transparent conductor. As soon as the capacitive touchscreen receives human touch, pressure builds up. This is a kind of electrostatic field and through it the change in capacitance is identified. Then it is identified by the processor chip of a mobile. In the next process, it is transmitted to the mobile software, so that the touch is identified and starts working.
Resistive Touchscreen
Resistive touchscreens have 2 layers with a conductive material in between. It works like resistance. When this display is touched with a finger, the material between the two, the upper and the lower one, forms a circuit as soon as it is touched. This touch is recognized by the processor chip of the mobile itself. After passing from there, it is recognized by the operating system of the mobile. Resistive touchscreens are less responsive than capacitive touchscreens. Many times this requires something like a stylus or pen. This technology is no longer commonly used in smartphones. You can now find this screen in the ATM machine.
