Unveiling the OLED Revolution: OLED vs LCD

Countless reports claimed that Apple would apply AMOLED displays on their next iPhone.

OLED has become a hot topic and inevitable trend since the news emerged.

What is OLED? What are the differences between OLED and LCD?

Will it affect the supply of China Made iPhone Screens?

We’ve got all the answers you want to know as below.

What is OLED?

OLED, which stands for Organic Light Emitting Diode, is made from organic light emitting materials that emit light when current is passed through it, being considered as a thin-film display technology.

Main types of OLEDs

The two most widely used OLED technologies are AMOLED and PMOLED.

The market of PMOLED is much smaller and more fragmented than AMOLED’s, as well as the development prospects.

News from trusted source reveals that Apple is expected to use AMOLED display in the iPhone 8 to save its shipments, which is in a continued decline.

What are the differences between OLED and LCD?

The biggest difference between these two kinds of technologies is that they have different structures, which really makes sense at the performance and application.

Since OLED does not require backlight and filters (unlike LCD displays), It is more efficient and much thinner – and in fact, can be made flexible and even rollable.

Below are the major differences between LCD and OLED derived from the disparate structures.

1. Backlight.

LCDs require a backlight but OLEDs do not need, they are self-luminous.

2. Size.

Due to the absence of backlight modules, OLEDs are thinner and lighter than LCDs.

3. Black level.

Compared with the “black” screens of LCDs, OLEDs can produce truly black screens.

For OLED, black pixels are simply pixels that emit no light at all.

However, for LCD, black pixels are done by covering all the white light with the help of filter.

Actually, this process turns out to be very difficult —there is always an amount of light being leaked.

4. Power consumption.

In a general way, OLEDs consume less power than LCDs for their self-light-generating. However, this is not always the case.

When white screens are far more than black screens, LCDs win the battle of power consuming. The advantage of OLEDs comes from black screens.

5. Viewing angles.

The thinner technology and closer pixels enable OLEDs the excellent viewing angles.

That means you can get qualified pictures no matter which angle you look from, dead center or far aside. Situations are generally worse in LCDs.

Depending on different display technologies, LCDs vary hugely from each other.

6. Color.

Colors of OLEDs were not so desirable and it’s hard to keep them realistic in the past. While now, it is much better for the application of new technologies.

Diversified as LCDs are, their performances are unlike depending on the specific technology used.

Like IPS and VA, after being properly calibrated, they can provide great color accuracy –iPhone 6s LCD is a vivid example of a phone with top color accuracy.

7. Price.

Affordable price is one of the advantages of LCD.

However, this supremacy would fade away in the long run as the rapid development of OLED.

8. Lifespan.

Undoubtedly, the comparatively long lifespan is another advantage of LCD.

OLED is a little bit worse at this aspect due to the short lifespan of the blue organic material.

What will the OLED bring to mobile phone repair industry?

If the next iPhone features OLED screen, what will happen in the mobile phone repair industry?

Many people have struggled with this problem since the news bubbled.

Judging from the market demand, Chinese iPhone Screens have dominated half of the shipments from the last quarter of 2015.

Will the application of OLED affect the supply of China Made Screens?

It’s hard to say, really. As the mainstream OLED suppliers, Samsung and LG have already acquired a monopoly position.

Chinese manufacturers, like BOE and Tianma, are trying to catch up with the tendency, but there are still some gaps existed.

There are likely to be some difficulties to meet the demand of OLED China Made iPhone Screens in the short term if the technology is truly employed.

Whereas the age of OLED is right around the corner, and China Made Screens will eventually come back with surprise.

Fight for Your Right to Repair | Quality iPhone Repairs

Your newly bought iPhone 7 is in a mess.

The power keeps dropping rapidly, the home button doesn’t work, the screen is cracked.

Yes, just some tiny hardware problems.

You could take it to an affordable local repair shop you trust, like those with REWA tech support all around the world.

The question is, however, they may not even know how to separate the LCD from the rest of the device ( REWA YouTube channel offers video guide for your need ).

Repair professionals as they are, to fix burnt-out LCD fuses and other esoteric and complicated repairs, pirated schematics online and advanced knowledge of how circuit boards fundamentally work are most needed.

Unfortunately, since Apple stopped handing out “Authorized Service Provider” designations, independent iPhone repair businesses have had no access to Apple’s internal service manuals and repair materials.

That means, you still have to turn to Apple’s official support system for help — so expensive that you can afford a completely new one.

Unbelievable? That’s how electronics work today.

Companies manage to make replacement parts and diagnostic tools difficult to buy and impose artificial software lockdowns on diagnostic systems within the devices, manufacturers refuse to publish crucial repair information and threaten those seen as defying them with a lawsuit for copyright infringement.

What we got in the end?

Fair uses are frustrated and users are deprived of their rights. Independent repair shops are driven out of business.

The electronic waste is piling up, poisoning the planet.

Sounds terrifying? Here comes rescue.

“Right to Repair”, the bill to enshrine the “Right to Repair” electronics, is aimed at the “authorized repair” model that creates aftermarket monopolies dominated by the manufacturers themselves.

It requires manufacturers containing embedded software or supporting terms for full repair and reuse to make available to consumers and independent repair shops diagnostic and service manuals, security updates, replacement parts and diagnostic and repair tools they need to repair those devices.

“It defends your right to own your stuff”, said Kevin Chou, CEO of REWA technology.

“It’s in society’s best interest to repair and replace, to reduce electronics waste and to protect our environment.＂

The logic goes that, if individual strength or a business can affordably repair a broken device, make sure that that device can last longer, somehow electronics waste can also be reduced, making it a win-win situation for both consumers and the environment.

Make sure ownership continues to mean something, and give owners control over their own devices.

Everyone can and should make an effort to lead the right to repair bill way into legislation and opening up the right to repair for all in the world.

Anyway, REWA will always be with you!

REWA’s Quality Classification for Phone LCD Screens
Have you ever been being confused by different qualities of LCD assemblies and worrying about purchasing wrongly?

Don’t worry, REWA will instruct you to distinguish them by several methods.

There are six kinds of different qualities for Mobile Phone LCD Screens, Touch Screen Digitizers and other Cell Phone Parts which are OEM NEW, OEM USED, OEM REFURB, AAA GRADE, AA GRADE and A GRADE.

Here we would like to emphatically introduce the quality classification for iPhone LCDs.

This post should walk you through the ways of how to tell the differences.

MULTI-DIMENSION DISTINCTION

– The glass lens comes with a colored ring.

– No excessive glue on LCD flex cable and bezel frame.

OEM NEW

– Original but used already, torn down from user devices.

– There are a few scratches on bezel frame.

OEM USED
- Compatible glass lens and no colored ring.
- No excessive glue on LCD flex cable but bezel frame does.
- Glass lens and bezel frame assembled by the 3rd-Party factory.
- Refurbished from originally used LCD assembly.
OEM REFURB
- Compatible glass lens and no colored ring.
- No excessive glue on LCD flex cable but bezel frame does.
- Glass lens and bezel frame assembled by the 3rd-Party factory.
AAA GRADE
- Compatible glass lens and no colored ring.
- Original LCD but compatible LCD flex.
- There is excessive glue on LCD flex cable and bezel frame.
- Glass lens, bezel frame and LCD flex assembled by the 3rd-Party factory.
AA GRADE

– All parts apply compatible materials and assembled by China LCD vendor.

– Compared with the above-mentioned LCDs which use In-Cell structure, this A-grade LCD uses G+G/G+F technology.

A GRADE

COLOR DIFFERENCE The display effects of sample LCDs here are for reference, they may vary with different LCD batches and vendors.

NOTICE: Above-mentioned “colored ring” is only a supplementary method to distinguish original glass lens from compatible one.

For the reason that it’s not always the case that all the AAA GRADE LCDs of different vendors or batches come with no colored rings on the glass lens.

How To Distinguish iPhone 6 LCD Screen?

Have you ever been confused by different qualities of iPhone 6 LCD screens in the market and do not know how to choose the right one you really need or else your customers actually want?

For many iPhone parts distributors or cell phone repair business owners, one of the most common misconceptions you find is likely the true meaning and understanding of the definition of AAA Grade LCD Screens and Original (OEM) LCD Screens.

As more and more Chinese iPhone screens came into the market which eventually got decent popularity unexpectedly, thus you get more options out there on account of their good performance in display and stability.

Of course, they get better pricing compared with OEM ones.

If you are a bit unsure, don’t panic! We are about to help you to define the root differences of the OEM NEW , AA Grade , A Grade (which respectively manufactured by TIANMA, JDF and LT) iPhone 6 LCD Screens.

I hope that you will be able to distinguish them in an easier way through FLEX CABLE DISTINCTION and COLOR DIFFERENCE .

FLEX CABLE DISTINCTION

OEM NEW

The lines on an OEM New screen flex cable are mostly curving if you check carefully.

And the background color is yellow.

(The glass lens comes with a colored ring around the camera ring, all ORIGINAL and NEW from OEM factory)

AA GRADE

(Original LCD but Compatible LCD Flex Cable, also glass lens, bezel frame and flex cables are assembled by the third-party factory)

The lines are almost the same as on the OEM New flex cable. But the background color is brighter.

A GRADE (TIANMA)

(All parts apply compatible materials, and assembled by China LCD vendors)

The two curving lines on the right side can be seen as a sign of TIANMA screens.

A GRADE (JDF)

The symmetric curving lines in the middle make it looks like a “door”. And there is also a small “door” on the right side.

A GRADE (LT)

The flex cable is wider than OEM New. Besides, it has yellow lines with the black background color.

COLOR DIFFERENCE

The display effects of sample LCDs here are for reference, they may vary with different LCD batches and vendors.

OEM NEW Original LCD with Compatible Flex Cable

NOTICE:

There are different ways to tell original iPhone screen from China Made screen.

Here we have the easiest and most effective way to distinguish different qualities of iPhone 6 screens through the lines on the back of LCD flex cable.

Now, would you like to check your screens through this way?

Understanding Qualified Batteries | REWA Battery Testing
As the demand for battery repairing is on the rise, and battery safety performance became global concerned, REWA has implemented a series of tests and analyses towards this hot topic.

Five Signs You Need to Replace Your Battery

For those low-quality batteries, it is not durable, or even dangerous.

Even if you use a high-quality battery, it will inevitably degrade over time and lose some of its charge capacity.

How do you know when it’s time to replace your battery?

Here are some signs that you have a dying battery.
- The phone drains fast
- Phone or battery overheated
- Cliff-like power drop
- Battery volume indication error
- Battery swelled
Causes of Above Mentioned Issues

There are many reasons why the above problems spring up.

Here some primary causes are summarized.

1. Battery aging

2. Self-consumption increasing

3. High temperature and power consumption caused by high internal resistance leads to nondurable battery power

4. Battery volume indication error

5. Low-quality materials and improper use result in poor battery charge and discharge reverse performance, which finally leads to short battery cycle life

6. The internal chemical reaction caused by high temperature produces gas

7. Unmatched battery and phone leads to the results that the phone cannot turn on or display normally

Harm Effects of Low-Quality Battery

Since the battery-related accidents frequently happen, the effects of low-quality batteries have emerged gradually.

Moreover, battery life became one of the biggest pain points for mobile users these days.

Will the faulty battery affect the phone performance?

Will these batteries explode in the high-temperature environment?

A step increasing number of people are struggling with these problems.

1. Small capacity, not durable

2. Short battery cycle life leads to a faster charge decay so that the batteries need to be replaced frequently

3. Battery volume indication error, insufficient discharge, and cliff-like power drop may lead to auto power-off

4. High internal resistance increases the heat and power consumption, thus the increasing temperature bring potential security risks

5. Protection start-up failure caused by poor performance protection board may result in battery damage, smoking, fire, explosion

6. Low-quality protection board may cause identification failure, connection failure and power indicator error

7. Protection board temperature measuring error makes the phone unable to have an accurate response to the temperature changes, thus damaging the phone

REWA Standards

After strict tests both in physical and electrical performance, here are the requirements of a qualified replacement battery for iPhone 6s:

Low-quality batteries do have bad effects on your phone, even your health.

Treat it carefully when you decide to replace your battery.

While cell phone batteries have plenty of suppliers, their performances can be variable.

How to choose the high-quality batteries?

Please stay tuned for detailed phone battery testing procedures and results .
