QLED And OLED: Who Is The Real Winner?

QLED And OLED: Who Is The Real Winner?

Mar 07, 2017

Talking about the title makes me think of an old saying in China, when two tigers fight, one is bound to get hurt. However, what we will talk about today, please read the following article patiently.

There is just a letter difference between QLED and OLED, but there are obvious differences in the technology and marketing. In 2017, Samsung has released a new QLED TV, What are the two technical lines of historical origin and technical differences? What kind of market evaluation and future prospects?

With regard to the history of the development of Samsung and LG in the field of television, basically with the change of television technology and the growth of. CRTPDPLCDOLED each stage of both companies have experienced or are experiencing. It is worth mentioning that, Samsung and LG have launched in 2012 55 inch OLED TV, and tried to commercialization in 2013, but not for a year, OLED's biggest supporters Samsung transfer strategy.

Certainly, one of the reasons, including Samsung and LG in the face of the core of the OLED core waterproof technology patent dispute, but more or Samsung in the market due to the flexible nature of the strategy.

2014 Samsung focused on the 4K LCD TV, released in 2015 SUHD TV, in 2017 to create a new QLED TV. In order to occupy the quantum dot technology, Samsung invested 300 quantum dot technology patents with the German Nanosys company, also acquired the United States quantum dot enterprise QD Vision. At the same time Samsung did not completely give up OLED technology, small size of the field of AMOLED has a rapid growth.

In contrast LG since 2012 has been adhering to the OLED camp, and constantly improve the technology and technology. In the direction of OLED material LG positive chemical closely with MITSUBISHI chemical, chemical Sumitomo, American UDC, German Covin company, to jointly promote the progress of the industry OLED materials.

So now we see the contest between QLED and OLED, in fact, is not just a contest between Samsung and LG, but behind the two technology research, product, marketing contest between groups.

QLED is different from OLED

In order to really understand the difference between "Q" and "O", it is necessary to analyze them first.

The ideal version of the QLED technology should be active light-emitting quantum dot materials, the application of the display device does not require backlight and color filters. At the present stage, "bate" is in the blue LED before the distribution of quantum dot film, the formation of higher purity backlight, through the liquid crystal molecules to bring more pure color performance.

The ideal version of the OLED OLED technology should be the organic material of active luminescence, RGB primary colors, color composition. But at this stage of the "bate" version is the use of W OLED technology, OLED only acts as a self light emitting, but compared to the mechanical rotation of liquid crystal, still have the absolute black and high contrast such characteristics.

So it seems that the two technology ideal version are self luminous properties, QLED is an inorganic material self luminous, OLED is an organic material self luminous, are very forward-looking display technology. But why is the market bate version of it?

In fact, OLED made the ideal version of the technology have, in 2014 CES launched SONY OLED TV is the ideal version, there are a lot of broadcast level display devices, including Samsung's AMOLED are ideal". But the market is a high efficiency and cost, WOLED compared to the RGB OLED has a better cost advantage and service life, more suitable for the promotion of the market.

The ideal version of a little development slowly, but after all, is the "OLED generation", the progress of a large space, the market will give more patience.

Then talk about the actual effect (compare with the bate version).

Brightness: Q wins. QLED using LED backlight, through the use of high brightness LED module, improve the backlight structure, you can further enhance the brightness. Like SONY's dynamic backlight master version of the peak brightness can reach 4000nit, Samsung's QLED can reach 2000nit, and can ensure that 15s does not decay. The characteristics of OLED organic light-emitting, high brightness is bound to be an organic light emitting body attenuation, resulting in physical damage can not be restored.

Black level: O wins. There is no doubt that OLED can completely turn off the backlight. QLED also has a local light control technology, but can not be a good control of each pixel (except SONY Z9D).

Refresh rate & response time: O wins. QLED liquid crystal molecules in the electrical signal after receiving a mechanical rotation process, and OLED like a bulb, the switch is completed in an instant action.

HDR:Q wins. QLED has a higher brightness, so in the same color depth and gray case, QLED will have a better dynamic range performance.

Color gamut: Q wins. We are all bate version, are backlit + color filter film mode, but the quantum dot spectrum has a natural advantage.

Visual angle: O wins. OLED can even approach 180 degrees.

Uniformity: O wins. OLED alone controls the characteristics of each pixel luminescence, enough to beat the local control of the QLED light brought about by the uniformity of the screen.

Gray: Q wins. Shadow detail and color transition problem whether it is WOLED or RGB OLED should be a cannot avoid a problem. Because OLED uses PWM or DC dimming mode. When the color of the panel to reach 10bit, that is, when the 1024 level, it is necessary to imagine the liquid crystal molecules that control the fine steering, is a very difficult thing.

Power consumption: Q wins. OLED power saving, is in the performance of the black scene, but the normal use, the same size of the OLED will be larger than the QLED power.

The comparison of so many, QLED and OLED bate version of the same can be said. No wonder the two camps are currently well-matched in strength state.

Who is the winner?

Why do we have to distinguish the outcome? We are concerned about the flexible screen technology, QLED and OLED printing technology, can be made into ultrathin flexible screen. Can not coexist? Not only is the bate version of peaceful coexistence, the future will be upgraded to an ideal version, the same will be peaceful coexistence.

In the display technology, we have different ways to achieve, but no one is omnipotent, there is always a certain complementary relationship. Just like in the business of online and offline, film and television in the 3D and VR, Chinese medicine and Western medicine, are the coexistence of the relationship.

However, it is certain to be able to distinguish the outcome, because the plasma was dry dead. What is the reason for this? The cost advantage of technology to improve the efficiency of deciding, who is the fastest speed, and reduce the cost, who can have the last laugh.
