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.

Which is the most cost-effective China made iPhone 6 LCD?

LT(IVO)

There are several display panel manufacturers in mainland China of which JDF(BOE) and TM(Tianma) stand out noticeably. JDF has gradually transformed its 6th production line into small-to-medium-size displays since 2014 and now JDF proceeds this plan and concentrates production capacity in this field in an all-around way.

As a matter of fact, TM(Tianma) has already transformed its display size and capacity altogether in late 2013 in prior of JDF(BOE), focusing on small-to-medium-size displays.

In addition to this, though SC which was vigorously supported by Foxconn had been performing mass production for LTPS, TFT, LCD displays at the beginning of 2012, did not make a great progress for the reason that SC failed to neither win over the Apple iPhone orders and nor get authorization in CG Si and IGZO technology of Sharp.

But do you know which iPhone 6 LCD made by these three display penal manufacturers is more cost-effective? Let’s go on with this article and sort things out. Not too long ago, REWA has analyzed the JDF(BOE) and LT(IVO) China made iPhone 6 LCDs in some ways. After several months’ development, how is the situation now? We have tested 3 mainstream China-made iPhone 6 LCDs by JDF(BOE ), TM(Tianma) and SC from aspects of “Appearance” and “Function” in order to make a comparison with OEM ones and give us clarity of thought.

Appearance

1) Glass Lens

There is no difference between JDF, TM and SC LCDs and OEM ones in appearance.

2) Button Hole Alignment

Through visual inspection we can hardly tell obvious differences among OEM, JDF, TM and SC LCDs.

3) Bezel

None of these three kinds of LCDs have deformations, breakages, looseness or degumming on front LCD Supporting Bezel Frames.

The front bezels of different type match LCD Back Metal Plate very well, it is still hard to tell differences between JDF, TM, SC and OEM ones.

In terms of bezel matching with LCD and touch screen assembly, all these three China made LCDs can be matched perfectly.

After installed in the mobile devices, it’s much easy for us to find that all these three China made LCDs have a small gap between the LCD and device body, especially SC.

4) Flex Cable

It can be observed visually that LCD Display and Touchscreen digitizer flex cable made by JDF, TM and SC are different in texture. 5) Structure Generally speaking, there are two kinds of mainstream cell phone display constructions of formation, “G+G” and “In-cell”.

Compared with the In-cell structure of OEM LCD, JDF, TM and SC which use G+G touch screen display technology thus cause their overall thickness greater than the OEM ones.

Function

1) Touch

Testing Touch screen digitizer by moving the app icon in all directions including swiping from the edge of the screen, JDF, TM and SC display have no problems with touch function.

2) Display

Testing LCD display in the pure color of gray, white and black, a part of JDF, TM and SC LCDs have somewhat degree problems of backlight leakage, but it does not affect the normal use and can be ignored in a certain sense. Note: The severity of this problem in the actual situation is a lot more slight than the captured pictures above.

3) Color Difference

By comparison, the visual colors of JDF, TM and SC made display differ from the OEM ones.

4) Aging Test

After playing video for 72 hours, JDF, TM, SC have no obvious differences with the OEM ones.

Conclusion

From a series of tests we can find there are only a few differences between OEM display and China made LCDs. In terms of quality, JDF & TM are better than SC. For Price, JDF is more favorable than TM. Therefore, on the market condition that OEM LCDs being out of stock, JDF LCD is the most cost-effective choice for you. Want to order our products?
