Professional LCD and Touch Manufacturer / Design Solution

Super AMOLED VS IPS which will be more popular In the future

The screen is one of the essential components of smartphones. At the launch of each smartphone, manufacturers will mention their parameters and characteristics. For users, watching videos, pictures, replying to text messages, and other necessary daily functions need to be operated through the mobile phone screen.

As far as the development of smartphones is concerned, the screen is no longer only playing the role of basic functions, but also one of the vital hardware devices to enhance the user experience. A high-quality mobile phone screen can not only bring convenient operation experience but also improve the visual effect for users so that users can have high-quality visual experience in a variety of complex situations.

 The same picture often has different display effect in different material screens, especially in saturation and contrast. Also, there are some differences in the display effect of various materials under sunlight. When many people watch videos and pictures, the problem of the viewing angle of the screen will be visible. The larger the viewing angle of the screen, the better the viewing effect will be.

At present, Super AMOLED and IPS screens are the mainstream of smartphones in the market. Super AMOLED and IPS screens are common in the middle- high-grade product series. So what is the difference between the two monitors? We might as well verify it through actual testing.

Practical comparison of saturation and contrast

 First of all, we can see the effect of opening the same picture on three kinds of screens in full black indoor. After observation, we find that Super AMOLED and IPS screens have good performance in some display details, but in color, Super AMOLED screens are more abundant than IPS screens, because every pixel of Super AMOLED dazzling screen can be self-contained. Luminescent, can present more than 90% of Adobe RGB color range, so the Super AMOLED screen looks more comfortable.

For users, it is essential to have excellent color and more profound contrast, but for photos, we should pursue their authenticity more. Therefore, the author uses a daily SLR photograph, which is viewed on three screens and compares it with the original SLR image to see whose display effect is better. Close to the original performance.

 Authenticity contrast

Looking the two screens effects, it would be nice to take anyone out alone, but putting them together still shows the difference in color, especially in the small part of the sunlight shadow in the photo, because Super AMOLED has good contrast and broad color model. Weiwei, therefore, is more realistic in general and can express the original flavor of the original picture better.

Contrast under actual use conditions

For a mobile screen, it needs to be used in a variety of complex environments, including the use of various postures and multi-user simultaneous viewing of photos or videos. At this time, the mobile screen is required to have a broader perspective. If the viewing angle of the screen is small, the color will indeed affect the visual perception of the viewing, or even the content of the screen can’t be seen clearly.

Visual Angle Contrast

In the aspect of visual angle display, we have selected several display screens which are common in the market. IPS and SuperAMOLED monitors have excellent performances. SLCD2 using AH-IPS technology inherits the high visual angle of IPS, while TFT screens still perform poorly in the visual aspect. Besides the problem of anti-whitening, the issue of color bias is more severe than other monitors.

Structural comparison

Because of the no backlight, The Super-AMOLED screen is often thinner than that  IPS LCD screen.

This on-cell technology is an advantage of S-AMOLED displays on smartphones, especially the technology that can make smartphones thinner than displays using IPS LCD.

 Screen Display Contrast in Sunlight

Finally, we compare the two LCD screens in the sunshine. IPS and Super AMOLED have good display effect. They can see the main content of the screen display, but Super AMOLED is slightly better than IPS in picture details.

Summary:

The quality of the LCD display will directly affect the user’s experience. To investigate how the LCD screen should proceed from the actual experience, the Super AMOLED screen has certain advantages in color reduction, color range, contrast, and visual angle range. In practical use, it is still excellent even under sunlight. For IPS technology that has been very mature, the high cost of Super AMOLED limits the popularity of products. With the promotion of OLED and the improvement of production technology, Super AMOLED will have more application space.

2023年CES展会将于1月5日在拉斯维加斯拉开帷幕,参展商中的323家企业来自世界500强公司,全球科技巨头LGD、三星、友达、TCL华星、索尼、华硕、夏普、元太、技嘉、TCL、大众、宝马等将带来丰富的创新成果。本届CES展会涵盖的重要主题包括可持续性、数字健康、Web3与元宇宙以及人类安全等。 LGD:发布第三代OLED电视面板 LG电子展览馆入口处,连接260片OLED柔性标牌的超大型雕塑“OLED地平线”吸引了游客的目光。 LG Display在美国拉斯维加斯举行的世界最大家电、IT展示会CES 2023上公布了使用新技术“META Technology 1.0”的第三代OLED电视面板。 当地时间1月4日,LG-Display发布的新产品采用了革新技术“META Technology 1.0”,比现有亮度(屏幕亮度)提高了60%,视角扩大了30%。改善OLED亮度和视角局限性的“Meta Technology”将超微镜头和亮度增强算法相结合,将OLED的光释放最大化,能效提高约22%。 据LG Display透露,第三代OLED电视面板将现有的1300尼特(nit,1nit是一支蜡烛的亮度)水平的峰值亮度大幅提高到2100尼特(HDR标准),体现了OLED电视面板中最亮的画面。 另外,通过被称为“微透镜阵列”(MLA)的超微透镜,克服了无法提高亮度的局限性。此前,有机发光层产生的大量光因面板内部反射无法向外照射而无法提高亮度,但在肉眼看不见的大小凹凸不平的镜片图案上沉积了自己发光的有机物,最大限度地提高了光的释放。 第三代OLED电视面板每像素精密制作5117个(77英寸4K标准)、共424亿个微透镜,将内部反射的光线发射到外部,可以实现此前没有体验过的明亮画面。 同时,就像蜻蜓以数百万个凸起的复眼结构观看360度一样,通过数百亿个微透镜提供现有电视中最宽的视角。将屏幕正面亮度的角度扩大到160度,比之前改善30%,无论从哪个角度都能实现准确的影像。 LG Display表示,今年量产的4K 55、65、77英寸和8K 77、88英寸等高端OLED电视面板将优先采用“META Technology 1.0”,今后将扩大到全部阵容,计划以此加强高端电视市场内OLED的主导权。 LG Display大型事业部专务李贤宇表示:“超差距技术‘META
