Everyone knows that a screen is composed of individual pixels, and what we call "1920 × 1080" actually refers to the number of vertical and horizontal pixels. The essential difference between OLED and LCD lies in their display principles. OLED can be simply understood as composed of countless red, green, and blue light bulbs that can emit light on their own, and macro display can be controlled by controlling the brightness and brightness of each bulb. And there will be a backlight panel on the back of the LCD, which displays different colors by passing through "filter paper" of different colors. ''



The working principle of LCD (Liquid Crystal Display) is to use liquid crystal molecules to change their alignment direction under the action of an electric field, thereby controlling the passage of light and achieving image display. LCD screens require a backlight source to illuminate the liquid crystal layer, and display is achieved by modulating the backlight source through the liquid crystal layer.



OLED (Organic Light Emitting Diode) is a self luminous display technology where each pixel can independently emit light without the need for a backlight source. When current passes through organic materials, light is emitted, and the brightness is adjusted by controlling the magnitude of the current.



Simply put, LCD is like a transparent piece of paper that requires sunlight or light to see the handwriting, while OLED is like a luminous panel that can emit light on its own.



What are the advantages and disadvantages of LCD and OLED screens compared?



The advantages of LCD are very obvious. Firstly, it does not have color cast like OLED. Secondly, LCD generally has full DC dimming or high-frequency PWM dimming. Therefore, another recognized advantage of LCD is that it is very eye friendly. In addition, LCD screens have a longer lifespan, even if it takes four to five years, it is difficult for the screen to burn out even if it turns yellow. LCD screens are more durable. ''

OLED screens have strong adaptability to new technologies, but they also have some drawbacks, such as easy burn-in, color cast, and relatively short lifespan. The burn-in phenomenon of OLED screens refers to the possibility of permanent pixel damage when a static image is displayed for a long time, resulting in residual images on the screen. And LCD screens do not have this characteristics of LCD OLED display principle: The backlight illuminates the liquid crystal layer, and the liquid crystal layer modulates the light to emit light independently. Each pixel can emit light independently. Advantages include eye protection, long lifespan, low screen burn-in, low cost, high contrast, fast response speed, and bright colors. Disadvantages include low contrast, slow response speed, uneven color, easy screen burn-in, color cast, and relatively short lifespan. Applications include televisions, computers, mobile phones, smart watches, VR devices, etc



From the table, we can see that LCD and OLED each have their own advantages and disadvantages, and there is no distinction between good and bad.





Is OLED or LCD better for mobile phone screens?



In fact, both types of screens have their own advantages and disadvantages. Although it cannot be directly measured by good or bad, what is certain is that due to the current development of smartphones towards full screen displays and the popularity of under screen fingerprints

From a technical perspective, OLED screens are the better choice because they are lightweight, have good display effects, and save power, all of which are means to enhance the user experience. From the user's perspective. ''



We also know that LCD technology has been developing for a long time and is more mature in terms of technology. Even with lower cost control, it can still display more natural and accurate color effects. ''



There is no standard answer to this question, and it needs to be judged based on individual usage needs and preferences.

If you are a user who pursues eye protection and durability, you can choose an LCD screen. LCD screens have better eye protection effects, longer lifespan, and are less prone to screen burn-in.



If you pursue the ultimate display effect, you can choose OLED screen. OLED screens have higher contrast, faster response speed, and brighter colors, which can bring a more immersive visual experience.





What are the future development trends of LCD and OLED screens?



In fact, there are significant differences between LCD and OLED in terms of display principles, energy consumption, and forms. OLED is relatively better as its light-emitting principle is more advanced. ''



With the continuous development of technology, both LCD and OLED screens are constantly advancing. The cost of LCD screens is decreasing, and there are also improvements in image quality and response speed. The lifespan of OLED screens is also constantly extending, and the problem of screen burn-in is gradually being solved.



In the future, LCD and OLED screens may be integrated and developed in more fields, such as Mini LED backlight technology and quantum dot technology, which will bring better picture quality and richer color performance.

It is necessary for us to learn how to distinguish between external and internal screen issues.



External screen broken: It's just that the glass screen of the external screen is broken, but the touch and display are normal. In this case, only the outer glass needs to be replaced, that is, only the external screen needs to be replaced.



Internal screen malfunction: insensitive touch or screen jumping;



The display is also incomplete, with blackened and yellowed parts on the screen, indicating liquid leakage from the LCD screen; Horizontal and vertical lines are all signs of a broken display screen and require replacement of the inner screen, which is the screen assembly;



If your phone accidentally breaks, we suggest you choose our screen. We offer various types of phone screens, including incell, OLED, LCD, reliable quality, easy installation, reasonable price, and after-sales guarantee.

Collaborative innovation, industry university research collaboration to forge the technological highland of "Chinese screen"

As a leading Chinese enterprise in the AMOLED field, Vishino has always been driven by technological innovation and has joined forces with Tsinghua University and domestic material manufacturers to launch technological breakthroughs in the field of OLED material devices. After years of research and development, the company has successfully overcome key technological bottlenecks and released the fourth generation pTSF material device system. This system has been comprehensively upgraded from three dimensions: luminous efficiency, color gamut coverage, and device lifespan. It not only achieves purer color presentation, lower energy consumption, but also extends screen lifespan. It has officially been put into mass production and commercial use, adding core chips to the competition of "Chinese screens" in the global market.

Technological breakthrough, redefining AMOLED performance benchmark

In the development process of OLED technology, how to simultaneously achieve high efficiency, long lifespan, and high color purity of OLED has always been an important research issue. Compared to traditional OLED devices, the fourth generation pTSF device technology introduces multiple energy transfer modes, ultimately emitting light from a fluorescent emitter, achieving 100% internal quantum efficiency utilization. Moreover, the exciton lifetime of devices using pTSF technology has achieved a leap from microseconds to nanoseconds, suppressing exciton annihilation and quenching processes within the device, thereby achieving higher efficiency and longer lifetime, as well as higher color purity.

As the "barometer" of the global display industry, the SID exhibition in 2025 saw Vishino launch high-efficiency pTSF device products and wide color gamut pTSF device screens globally, which attracted widespread attention in the industry for their performance. Data shows that screens equipped with high-efficiency pTSF devices reduce power consumption by over 12% and increase lifespan by 15% compared to traditional devices. Taking a smartphone with a daily battery life of 10 hours as an example, installing this screen can increase usage time by an additional 1.2 hours, effectively solving the pain point of "fast screen power consumption" in mobile devices. The wide color gamut pTSF device body has achieved breakthroughs in color reproduction, covering DCI-P3 color gamut (>99.5%) and Adobe RGB color gamut (>99.5%), with color accuracy reaching professional design level, meeting the needs of professional scenarios such as image creation and graphic design, while reducing energy consumption by more than 6% and increasing lifespan by 20%. At present, high-efficiency pTSF devices have completed mass production and begun to be applied in various mobile electronic devices in batches.

The technological breakthrough of Weixinnuo cannot be separated from the support of the industry university research collaborative innovation system. As a pioneer in China's OLED industry, the technological roots of Weixinnuo can be traced back to the OLED project team of Tsinghua University in 1996- it was this early technological exploration that accumulated a solid research and development foundation for the company. As of now, Weixinnuo has applied for over 20000 OLED related patents, with invention patents accounting for up to 89%. The patented technology covers the entire industry chain, including materials, devices, processes, and equipment, forming a complete technical protection system. In terms of industry standards and innovative achievements, Vicino has broken the monopoly of foreign enterprises: it is a Chinese enterprise that * formulates international standards for flexible displays, has won more than 20 global "*" innovative technologies and applications, more than 50 national "first" breakthroughs, and has also won the "first prize of the the State Technological Innovation Award" of the display industry *, becoming the "synonym" of China's display technology innovation.

In November 2024, Professor Duan Lian from Tsinghua University gave a keynote speech on the improvement of OLED performance at the screen technology press conference held by Weixinnuo. The two sides had in-depth exchanges on the research and development details and application scenarios of pTSF technology, further deepening the cooperation between industry, academia and research. In fact, the breakthrough of pTSF technology is the result of long-term cooperation between the two parties. The advantages of Tsinghua University in the field of basic research complement each other's experience in industrialization, accelerating the process of technology from the laboratory to the market. Practice has proven that the advantages of pTSF technology in key indicators such as color purity, efficiency, and lifespan not only validate the effectiveness of industry university research collaborative innovation, but also provide a replicable model for the technological upgrade of "Chinese screens".

The mass production and commercialization of the fourth generation pTSF material device system by Visionor is not only an important leap forward for the company's own development, but also promotes the key transformation of "Chinese screens" from "technology *" to "product *", which is of milestone significance in the global display industry. This achievement marks that "Made in China" has completely shed its identity as a "follower" in the AMOLED field, and has become a "leader" in the industry through independent innovation. In the future, it will continue to promote technological changes in the global display industry, allowing "Chinese screens" to shine even brighter in the global market.

The performance of the Chinese market is particularly outstanding. Starting from 2023, the Chinese market will surpass other markets and become the world's largest foldable screen mobile phone market. IDC predicts that in the next five years, the proportion of the Chinese market in the global foldable screen mobile phone market will remain stable at over 40%.

Specifically, in the first half of this year, the shipment volume of foldable screen smartphones in the Chinese market reached 4.98 million units, a year-on-year increase of 12.6%. Among them, Huawei's performance is particularly prominent, occupying 75% of the Chinese market share with a record high of 3.74 million units.

Specifically, in the first quarter of 2025, Huawei shipped 2.84 million units, accounting for approximately 76.6% of the market share; Following closely behind are brands such as Honor and OPPO, but far behind Huawei. Although there was a slight decline in the second quarter, Huawei still maintained its dominant position with a market share of 72.6%.

IDC pointed out that Chinese manufacturers are generally leading the global popularization of foldable screen technology by relying on mature local supply chains, high user acceptance, and precise market strategies. Huawei not only successfully boosted sales, but also promoted the localization of materials and core components in the industrial chain, further enhancing China's independent and controllable capabilities in this field.

Of course, the most significant feeling for consumers is that the current foldable screen prices are becoming increasingly affordable. In fact, this is also the result of the continuous expansion of the market and the continuous decline of supply chain costs. And more affordable prices can further drive market growth, thereby driving down the prices of foldable phones and gradually replacing conventional phones. So the question is, have you used a foldable phone yet?
