Not sure which option to choose? To understand, you need to have an idea of the specifics of the work of both matrices. We will tell you about this.
Features of AMOLED display
Specificity of work and advantages
AMOLED technology in smartphones implies the use of an active matrix screen with organic light-emitting diodes. The electrons transmitting current regulate the brightness of such a display. The parameters of a particular color are set by independent LEDs. The editorial board of expertology.ru has published the results of the study of the best smartphones in the budget and mid-price segment.
Key benefits:
Low power consumption when displaying dark colors - since the pixels of the screen glow independently from each other, they burn weakly when displaying dark colors. Accordingly, the AMOLED screen uses little battery power. But for light colors, the power consumption can be even higher than that of IPS.
Instant response - pixels respond to a matrix query very quickly (the speed is an order of magnitude higher than that of IPS). Gadgets based on AMOLED technology provide fast frame rates when displaying a dynamic picture: it turns out smoother. This is a definite plus for interacting with VR or in games.
disadvantages
Pixel burn-in - AMOLED has a memory effect - this leads to a gradual decrease in color accuracy and color distortion.
Distorted color rendition - due to the constant glow of blue pixels (they are perceived visually brighter than other colors). This problem is solved by a special modulation of brightness, but the eyes will quickly get tired.
IPS display features
Specificity of work and advantages
IPS technology in smartphones involves the use of a liquid crystal matrix. The image is created by the polarized light generated after passing through the color filter. Brightness control is possible thanks to filters that work on all pixels (regardless of their activity).
Key benefits:
Fixed power consumption - when forming a picture by means of liquid crystals, there is almost no power consumption (LED backlight "eats" more energy). The discharge level is not determined by the image, but by the brightness of the screen backlight.
Affordable - As IPS technology has been adopted by many brands in recent years, it has made it more affordable. For example, an IPS screen with FullHD resolution is very cheap (from $ 10). This makes smartphones as affordable as possible for consumers.
disadvantages
Long response time is invisible when solving basic tasks, but when working with VR content, the performance is not the highest. The frame rate decreases noticeably, the picture becomes less smooth.
Weak contrast - this one is especially striking when displaying dark tones and a black screen (it will be grayish).
What's better?
There is no definite answer to this question. This is a matter of taste and personal needs, since during the operation of most smartphones, the listed disadvantages of both matrices are especially invisible.
