Half Screen Black iPhone (Causes and How to fix)

As an iPhone owner, I’ve been frustrated when I attempt to use my device and the half of the screen is completely black. After doing some research and testing various solutions, I’m here to share how I solved this issue, as well as other solutions I discovered in my search. In this blog post, I’ll be exploring the causes of a half-screen black iPhone and how to fix it.

Why Has Your iPhone’s Screen Gone Black?

To solve a screen problem, you better learn the components of an iPhone’s screen and how it works, so let’s take a look inside the iPhone. 

We can look at the iPhone screen as two components; the logic board, which is the base for all electrical functionalities, and the display. 

The display is connected to the logic board. Thus, the logic board is the component that decides what you see on the screen.

If the cable connecting the two parts goes loose or dislodges by accidentally dropping your phone, you’ll see a black screen at the affected part of the screen.

However, the display has two parts called LCD screen and a digitizer. The digitizer’s job is to translate your touches on the LCD screen into digital information. 

Each element is connected individually by its cable to the logic board. Hence, the partial or complete blackness of the screen. 

Force Restart Your iPhone

How would I diagnose a defect? There’s a quick fix to try. After you charge your iPhone, force restart will rule out software glitches. Here is how to do it. 

For iPhone 8 or later and iPhone SE: Press and release the volume up button quickly. Press and release the volume down button quickly. Then, press and hold the lock button and wait for the Apple logo to appear. 

For iPhone 7 and 7+, press and hold the lock and volume down buttons simultaneously and wait for the Apple logo to appear. 

For iPhone 6s or earlier, press and hold both the lock and the Home button and wait for the Apple logo to appear.
