 1): Organic light-emitting diode (OLED)AMOLED:- As we now in this type of display three main parts organic component, emissive, electroluminescent we are using these three for making OLED display, there is a transparent electrode and inside the organic component electrode Here, we take the transparent electrode which is filled with organic components and When we provide electricity, then the organic components show phenomena of some light. This involves light-emitting and changing the color according to the picture, electroluminescent We see every day like a digital watch in which the characters look black Due to the chemical reaction on the electric current, it has transformed that part into a black body. The best form of this is seen in OLED, emissive phenomena occur When material moves from high energy state to low energy state, it generates radiation So that we see the screen leg light So there is no light source in it. This gives a better contrast in the background, which is good and energy-efficient with LCD, OLED works by keeping both of these phenomena and that s why it has a higher refresh rate.it is of two types passive & active OLED.

Arduino: OLED DISPLAY!!



      Passive OLED: -The passive OLED was its initial stage because it had a lot of power usage, as well as the color contrast in it was not right, the reason for this is here because in this anode-cathode requires constant energy to maintain the picture on the screen. Due to this, its power consumption is high and it has to maintain the current flow to keep the screen till the next refresh signal is received, so the power consumption is high as well as lower picture quality.

Active OLED(AMOLED): -AMOLED worked on the shortcomings of some of the POLEDs with a solution that made it a futuristic technology. In the field of display, AMOLED has a few key points for high contrast, color, flame power consumption compared to LED, etc. It is used in this TFT Thin Film transistor layer is used which allows the flame power to a different state of the capacitor and till the next refresh signal Takes the main role in maintaining his state until null is found

 Current generation


 1): Cathode-ray tube (CRT): As we know about it there is a vacuum tube electron beam and electrons hit phosphorus stuff that glows when an electron hits that all about we know in general
but some drawbacks in this type of displays bulky or heavyweight big screen need more power, Lifetime reliability of this type of display is more than all the displays in this list, there is no doubt about it. you agree with me.

2): (Monoscope)Liquid-crystal display (LCD): A fluid crystal display ('liquid crystal display', abridged: LCD) is a type of display (display) that is used to display text, images, videos, etc. electronically. It does not generate any light on its own but modulates the light falling above another source.
A fluid crystal exhibition is made up of elements with different shapes of liquid crystals. Under the influence of the external electric field, these liquid crystals change their orientation. Changing the orientation of these crystals also changes the polarity of the light falling on them. Which determines the visibility/invisibility of that crystal-element.
With this, displays of computer monitors, TVs, a panel of devices, and consumer items used in normal life (such as calculators, wristwatches, etc.) are made. Being light, portable, running with less power, ease of construction even in large size are its main features.
In fact, it is an "electronically-modifiable optical device" made up of several elements/pixels (pixels) filled with liquid crystals.

3):   Light-emitting diode display (LED): In this type of display technology-led arranged in sequence of an array that makes a pixel. the backlight is not a separate or individual unit is the basic part of the pixel, in this case, pixels made up by small tiny LED we know about LEDs, there are three LEDs Red, Green, and Blue with the help of these we make millions of color combination.

IPS - In-plane Switching LCD Monitors:

In-plane switching (IPS) was one of the first refinements to produce significant gains in the light-transmittance characteristics of TFT panels. Developed jointly by Hosiden and NEC, it is a technology that addresses two main issues of standard twisted nematic (TN) TFT displays: color and viewing angle.
With IPS, the crystals align vertically rather than horizontally on the screen, and an electric field is applied between each end of the crystal molecules — called the lateral electric field. In this way, the crystal electrodes are placed parallel to the pair, and thus the screen is the glass substrate. Liquid crystal molecules are not anchored in the lower glass substrate, so move more freely in the desired alignment.
