Why the problems still persist after screen replacement?

  If you dropped your smartphone, your touch screen may have some tough problems. A cracked display is one of the most obvious signs of a damaged screen which may cause all sorts of problems. The delicate layer is susceptible to damaging. After you finished the LCD screen digitizer replacement, there still will have some side effects and subsequent issues if you buy a poor quality screen digitizer parts. The most common issue is a dim screen. Your first action is to reboot this unresponsive smart device. Let us take a look at the reasons behind the dim screen.

  The root cause behind this issue is damage to the backlight circuit behind the screen. Ordinarily, this component is not easily damaged; however, some screens have an exposed backlight solder joint on the flex cable. This is especially true of low quality screens. During the reassembling of the phone, the backlight circuit can get shorted, resulting in the aforementioned screen dimming. There are a few other causes discussed below. What can be done to rectify the problem? The first thing to do is to ensure that you are using a genuine component to replace your old screen. It is best to use a genuine, Apple approved screen; as this drastically reduces the chances of the screen dimming problem occurring. There are high quality third party screens available. Make sure you do proper research before choosing a replacement screen. Examine the iPhone’s circuit carefully for signs of damage, especially the micro ribbon plugs. Burnt connections from the screen assembly to the motherboard can sometimes cause the dimming issue.

  One other thing you can do is to replace your backlight circuit with the one from your old screen. This will serve to resolve the problem temporarily, but if you are replacing your iPhone’s screen, chances are there is already something wrong with your old backlight. One obvious iPhone dim screen fix is to ensure that the brightness has been turned up in the iPhone’s settings, since screen replacement can sometimes reset the screen brightness. Certain accessibility settings can also cause this issue. This sometimes happens after iOS updates. If this is the case, it can easily be rectified by opening the Settings app and navigating to General -> Accessibility -> Zoom and disabling Zoom.

  A malfunctioning light sensor can also cause this problem. One way to identify this is to reboot the iPhone and observe the brightness of the Apple logo. If the Apple logo is bright, but the screen dims on boot, the problem is due to a malfunctioning light sensor. Repairing or replacing it will fix the issue. You can also try reseating the iPhone’s camera sensor, light sensor and speaker and see whether it fixes the screen dimming. If backlight circuit is the culprit behind your screen dimming as discussed earlier, you need to examine the backlight circuit, find the dead filter fuse and replace it. As always, do not attempt board level repairs if you are unsure or lack the necessary tools or knowledge. If your screen dimming persists even after trying all of the above, it may be best to take your iPhone to an Apple store or third-party retailers for replacement or repair.

  One of the effective ways to deal with this problem is that you need a LCD screen replacement if your problems still persist.

Different technologies and structures of iPhone LCD screens

iPhone 4 screen replacement

  A good quality iPhone LCD copy is due to appear in the market. So far, no negative reactions and feedback. We all know that iPhone LCD prices are soaring, with no chance to drop soon. Although the high cost of OEM parts is a solid reason for the mobile phones repair community to be upset, putting on a test some after-market screen assemblies won’t be a bad choice. How many screens do you know in the current market? In the following part, I’ll give you the details.

Nowadays, Apple is working on increasing their control of OEM parts marketplace and accredited after-sale services. Furthermore, the original screens for iPhone 5S are predicted to be no longer available on the market as Apple plans to retire this model from the market in the near future. With such a discouraging perspective, cell phone repair community should consider alternative solutions, such as copy iPhone LCDs to meet clients’ demands. But, for such an endeavor to take shape, the quality of after-market products has to be outstanding so they can successfully substitute original OEM parts.

Structure and technologies of LCD screens

As you know, in most smartphones, the touch screen’s structure consists of a digitizer touch screen and the glass lens. The digitizer’s performance, features, and functionality strongly depend on the material it is made of, such as film and glass.

TM LCD screen

Compared to OEM manufacturers that use In-cell technology to build LCD screens, after-market LCD manufacturers must rely on more economical methods and options due to the risks and costs involved. The G+F technology adopted by TM manufacturer is based on a sensor part built on a film layer. After it, the film layer is assembled with the glass lens. The result is a digitizer touch screen whose features are quite similar to the OEM’s. If you look carefully, you can even notice the film edge that could be easily removed.

LT LCD screen

To build the LCD screen, LT manufacturer uses the OGS technology. The glass lens and the touch sensor are embedded together and covered with a very thin lens to ensure the digitizer works properly and responds accurately to the commands from fingers. LT screens are very thin, to such an extent that, if we look carefully, we can see the diamond structures and the dots under the cover lens.

JDF LCD screen

In building the screen, JDF uses the “glass plus glass” technology (G+G). The digitizer touch sensor and the glass lens are assembled together. This structure is then covered with the cover lens. The result is the touch screen assembly. Although the thickness of the touch screen is wider, the main advantage of the G+G technology over other technologies (such as LT OGS described above) is that when the screen breaks, the digitizer continues to work properly. Thus, users don’t have to replace the full assembly, but the broken glass part. Both G+G and G+F technologies are similar from this point of view. However, the G+G allows lighter on the screen, so the display looks more transparent and brighter. New iPhone7 models use G+G OEM screens.

As we can see, both TM and JDF technologies have the advantage of a functional display in case of an accidental, unexpected screen break. However, when it comes to light reflection, the G+F structure does not excel, although is features a thinner profile of the screen. On the other hand, in JDF screens, the light crosses through the glass much better, and the display is brighter. So, the different manufacturing technologies directly influence the performance levels. Considering the contrast shown in the two images above, we can see the TM and LT technologies are the only ones that stretch the digitizer to the bottom. Thus, these two types of assemblies feature a smooth and soft surface in the proximity of the home button on the bottom. This distinctive property allows engineers to distinct LT and TM from others types of displays. With regards to color display performance, TM is the best. JDF displays are a bit yellowish, but they don’t have a negative impact on the overall experience in daily usage.

It depends on what type of replacement you prefer to buy depending on the iPhone replacement cost you can afford and other factors. If you think you don’t want to give away the true experience of using iPhone, then always get the OEM screen replacements and get best quality iPhone LCD display. Otherwise, you could look for good quality high copies as they do the same thing but are on the low end in terms of quality and durability.

There are many other problems experienced by iPhone users today. Below are some of the common iPhone screen problems and some tips on how to fix them.

1. iPhone LCD flashing

Did you perform an iOS 7 upgrade recently? For most users the upgrade was painless but a few phones had display issues because of the app compatibility problems. If it is the hardware fault giving rise to LCD flashing problem, it must be the faulty LCD screen or loose connecting cable. The chances of having a faulty LCD screen is more likely than a defect in the connection or internal circuit. Getting support from Apple based on warranty is often a struggle. It is simpler and easy to get a cheaper repair from the local store. The LCD replacement is not a difficult task like many would think. You can do it by yourself after buying a repair kit. The kit comes with a new replacement and the tools required to do the repair. Or else you can get an LCD replacement screen and contact the repair shop.

2. iPhone LCD blue lines

To solve this problem try pressing the power and home button at the same time. The phone reboots and the apple logo appears on the screen. If this step doesn’t work, you can hold the sleep/wake button and home button at the same time. Next hold the home button and plug to the computer or laptop using a USB cable. Hold the home button until a message regarding factory settings appears on the screen.  Click on restore to get the screen functioning correctly.

3. iPhone LCD keeps fading to black

You get this problem usually after the screen is replaced. Black vertical lines appear on the phone screen, sometimes these can be horizontal lines as well. The reason for this could be bad quality screen part fixed or loose connections. If you had fixed a broken screen by yourself then make sure you have done it properly.
