Screen Settings on Apple Devices- What You Didn’t Know

Screen Settings on your iPhone – Did you know this?

There are three parts that make up your phone screen, the Glass, Digitizer and LCD. People ocasionally notice a difference with their LCD after a screen replacement and ask why. In this blog we tell you about the process your phone screen goes through and how to get it back to your liking after a screen replacement.

Every screen (LCD) is slightly different, and the colours of an LCD are controlled via the GPU (Graphics Processing Unit). The phone LCD’s are individually programmed at the Apple manufacturing plant before they are put out onto shelves. Then programming process is done by a high-tech machine which uses cameras to look at the intensity/brightness of different colours on the LCD, and adjust them accordingly with the GPU.

Once it is done by Apple it is closed off and finalised. However, with a screen repair we can manually adjust it in the settings, just not the same way as Apple as it is not available to any 3rd party organisations.

From iOS 10 to the latest version, iOS 12 you can use Display Accommodations on your iPhone, iPad and iPod touch. To use Colour Filters and Invert Colours to change the way your screen appears on your Apple device.

To find Display Accommodations go to:

Changing every aspect of the screen such as visual media, although you may want to turn it off while viewing media. You can choose from four pre-set colours, grayscale, red/green which can help those with Protanopia, green/red which can help those with Deuteranopia, blue/yellow that can help those with Tritanopia and a colour tint which can help those who have light of colour sensitivity.

Colour Tint

The colour tint setting is what we advise adjusting as most LCD’s come with a yellowish tint. Adjusting the tint to the blue end of the scale and lowering the saturation can help counteract it.

White Point

Enabling white point dims the brightness of whites and brighter colours which can help those with sensitivity to bright colours. It differs from just turning down brightness to dim your screen. White Point adds an overlay or fog making the white point less harsh.
