Why AMOLED – screens are friendly with black colors?
It's all about the manufacturing technology of such matrices. Conventional IPS-displays have a backlight around the perimeter of the screen, which, passing through the filters, shows the desired color. AMOLED – Displays work differently. In such screens there is no general illumination: each pixel is a series of subpixels of different colors (blue, red, green), a subpixel is a small diode that can operate in two states (on and off). This allows you to completely turn off the diodes on a black background, which significantly saves battery power. However, there is a problem – pulse width modulation (PWM).
What is PWM?
PWM or Pulse Width Modulation is a way to adjust the brightness of OLED – displays. At 100% brightness, the screen pixels always work, but if you start to lower the brightness, they will quickly switch from active to inactive, creating a visually low brightness effect. This flickering of pixels is detrimental to vision. That is why DC-Dimming technology was invented.
What is DC-Dimming?
This technology allows you to remove the negative effects of PWM. It will not be possible to get rid of pulse width modulation completely, but the flicker itself will be noticeably smoothed out, which will make the negative impact on the eyes minimal.
