New Delhi.While buying a mobile, this thing definitely comes in our mind that what kind of screen mobile should be taken.By using which screen we will get better results and so that our eyes are not harmed.These days there are many types of phones in the market and different types of displays are being found in them.Each display has its own unique feature.In such a situation, the biggest challenge for you is that how do we find out which display is good and which is not.Let us tell you that the display is mainly categorized into three types, LCD (Liquid Crystal Display), LED (Light Emitting Diode) and Retina.LCD Display: LCD stands for Liquid Crystal Display.In this display, there is a light in the background of the pixels, which is called backlight.This light gives light to the pixels to project the content.Mobile has TFT LCD Panel, IPS LCD Panel, and SLCD Panel.Their quality also varies.Thin Film Transistor Display is considered to be the cheapest display in TFT LCD Panel LCD.Each pixel in this display is connected to a capacitor and transistor.With this display, we get to see images with high contrast ratio and it is also cheap to build it.A. AMOLED (Active-Matrix Organic Light Emitting Diode) This technology is from Samsung.In AMOLED display, the pixel itself acts as an LED bulb, due to which it does not require backlighting.This technology helps in saving electricity.When the color of the video becomes black, the pixels in that place stop projecting light, which makes the color look black.B. OLED Display This technology belongs to LG and LG has also taken a patent for it.This display is also similar to AMOLED.OLED consists of a series of thin films between two conductors, from which light is emitted whenever current passes through it.3. Retina Display Retina Display is a trademark of Apple Company.Apple modified the IPS LCD display and changed it to the Retina display.In retina display we can see higher PPI (Pixel Per Inch) than in IPS LCD display.Retina display comes in Apple mobile phones.Tags: Tech news hindi, Tech news in hindi, TechnologyAsia Cup: Poor performance of Rohit and Co...
