Display Flickering Problem in Oled Display
Display Types and their Work
In this time technologies are very popular in smartphone industries. Every day we can see the new technology where use in smartphones. Like component in Battery, Camera modules, sensors, in processor in Design and Built, and also in display quality. These component are always be improved in time to time. But in the main part of smartphone is their Displays. Display always be a highlight point in a smartphone. So every smartphones companies are try to provide a best killer quality Display in their smartphone for very good Viewing angle, and provide best quality and best color reproduction of display. So, verity display Panels are comes with verity of smartphones like IPS Display, Amo led Display, Tft Display, and OLed Display. In 1-or 2 Years ago many Budget-mid range smartphones are comes with Tft Panel in their display and flagship smartphones are comes with Amoled Display. But in this days many smartphones comes with Ips Display panel, Mid range smartphones come with both Ips and Amo led Display and Many Flagship smartphones comes with Oled Display Panel. But every display panel has a negative points like in the Ips Panel provide us True to Reality colors But its doesn't provide extra brightness and punchi colors like Amo led Display, Amoled Display provides us Extra vivid brightness with Punchi colors but its not true to Reality colors but In oled panels we found good Display experience like true to Reality and Very good Viewing Angle with Brightness. But in this Panel also have a negative point, Basically in this panel works with Purls width Module.
What is PWM ?
PWM (Purls Width Module)
is used in Oled Displays for control the Brightness level. When We on our
display Brightness in 100% PWD system is always on through the display, But
when Decrease our brightness in 80 or 90 % this system is works on up-down
display concept. In this concept when we decrease our screen brightness.
Display has been off many times and display is on some of times. This is called
Display Flicker. Like the below picture format.
What is Display Flickering ?
This pwm technology is use only
in Oled Smartphone display, because in use of this technology we cannot lose
the display quality and viewing angle and resolution in 10% Brightness level.
In this process display has been flicker in low light many sensitive people can
detect this flickering process for the reasons they face problem with their eye
and head. But In Ips And Amo led Display has been Comes with the inbuilt DC
Dimming Technology it is very simple technology in this technology when we use
our Smartphone in 100% mother board provide full power to Display and When we
Decrease our brightness in 80% or Any percent mother board provide very low
power capacity to Display. Where we cannot see any display flicker problem but
in this feature when we decrease our brightness we lose the display viewing
angle and Display Quality. So, now a days oled Smartphones are comes with Dc
dimming Technology in Optional in smartpohnes brand like Samsung, Oneplus,
Apple, Huawei and Google. Either they can enable and disable this dc dimming feature.
