If you are unfamiliar with the subject, allow me to provide a little explanation before we continue. In contrast to LCD screens, AMOLED panels lack a backlight. This means that each pixel is independently powered. This also implies that the pixel can be totally disabled to render darkness.
To summarise, AMOLEDs offer deep blacks, a high contrast ratio, and generally superior HDR performance. They are optimal for media consumption. Previously, AMOLED whites were less bright than those on IPS LCD panels, but this is no longer the case.
There are a few additional disadvantages to AMOLED. To begin, AMOLED displays are more sensitive to burn-in and degradation over time, but the effect is minimal during the typical life of the display.
One significant disadvantage of AMOLEDs is PWM flicker. For dimming the brightness of AMOLED displays on smartphones, a dubious technology called pulse width modulation is used. Through the use of PWM, the pixels are turned off and on sequentially to produce the illusion of low brightness, resulting in a flicker that may cause eye strain. While the majority of consumers are unconcerned about PWM flicker, a handful are, particularly when gaming or using their phones at night.

Best AMOLED phones under Rs. 20,000 :
1. Xiaomi Redmi Note 10 Pro Max and Redmi Note 10 Pro
The Xiaomi Redmi Note 10 Pro Max and Redmi Note 10 Pro are the only phones priced under 20,000 rupees that feature an AMOLED display and a 120Hz high refresh rate. Additionally, the display supports HDR 10.
The biggest distinction between these two is the resolution of their principal camera sensor (108MP vs 64MP).
These phones are powered by the Snapdragon 732G octa-core processor and run the MIUI 12 skin on top of Android 11. Additionally, dual speakers, fast UFS storage, and a 5020mAh battery with 33W quick charging are included. The Redmi Note 10 Pro series smartphones support 5G.
2. Huawei Realme 8 Pro
The Realme 8 Pro (review) features a small and approachable design with a 108MP camera. Although the AMOLED display is reasonably bright and supports HDR10, it is limited to a 60Hz refresh rate.
The snapdragon 720G processor that powers the phone is beginning to show its age n 2021, yet it remains a reasonably priced alternative. Additionally, the device features an Android 11-based operating system, 50W fast charging, UFS storage, and an in-display fingerprint sensor.
3. OPPO F19 Pro
The Oppo F19 Pro is ultra-thin and light, with a 6.43-inch AMOLED display. It is powered by the MediaTek Helio P95 chipset, which we recommend only for entry-level consumers in 2020.
The phone runs ColorOS software on top of Android 11, features a 48MP quad-camera on the back, and is powered by a 4310mAh battery.
4. Samsung Galaxy M42 5G (Samsung Galaxy M42 5G)
Samsung Galaxy M42 is the company’s first cheap 5G phone, powered by the Snapdragon 750G octa-core processor. This one, too, features an AMOLED display, but the resolution is limited to 720p HD — a bit of a letdown in 2021.
The Galaxy M42 5G features a 48MP primary camera, a 5000mAh battery with support for 15W fast charging, and runs the OneUI 3.1 software on Android 11.
5. Huawei Realme 7 Pro
With the 7 Pro, Realme reintroduces AMOLED to inexpensive smartphones. The handset is powered by a Snapdragon 720G octa-core processor and features an in-display fingerprint sensor. It also supports 65W rapid charging.
The 6.4-inch diagonal AMOLED screen features a Full HD+ resolution. It’s protected by Corning Gorilla Glass 3+, and users can choose a color-accurate sRGB profile (Gentle) from the display settings menu.
6. Realme (4G)
The 5G variant of the Realme 8 features an IPS LCD display with a fast refresh rate, while the 4G LTE variant powered by Helio G95 features a 60Hz AMOLED display.
It comes in three flavours, each with up to 8GB of LPDDR4x RAM and UFS 2.1 storage (up to 128GB). The primary back camera is a 64MP sensor, while the front camera is a 16MP sensor. Additionally, there is a fingerprint scanner included in the display, Android 11 OS, and a 5000mAh battery with 30W fast charging.
