Off-screen camera solution

It has been several years since the mobile phone entered the era of a full screen. Whether it is a lifting screen or a perforated screen, the current full-screen design has many disadvantages. The ideal full screen needs to solve the problem of the camera under the screen.

Today, Let’s introduce what is the “under-display camera solution, really 100% full screen‘

This solution achieves the best balance between display effect and screen transparency by developing and applying new transparent OLED devices, new driving circuits and pixel structures, and introducing highly transparent new materials.

In order to realize the off-screen camera function, the transparency of the camera area (hereinafter referred to as sub-screen) must first be improved. This time we started with the screen material, selected new organic and inorganic film materials with higher transparency, and enhanced the transparency of the film layer structure; optimized the metal layer structure of the screen body-transparent conductive in the sub-screen area The layer replaces the non-transparent metal material to the maximum extent, and the metal layer that cannot be replaced by the transparent conductive layer uses a new material, so as to achieve the dual effects of improving transparency and suppressing diffraction.

On the basis of updating materials and optimizing the structure, Visionox further “cleared” the interference factors of the secondary screen area, using the industry’s first drive circuit and pixel structure design to avoid the interference of the pixel drive circuit on the camera and suppress the transparent area The effect of display traces and pixels on the front camera greatly improves the front camera effect.

Of course, in addition to improvements in hardware, the software algorithm of the front camera can also complement the shooting effect of the secondary screen area.

Through cooperation with terminal manufacturers, Visionox’s AMOLED has further eliminated the diffraction and glare that affect the shooting effect, suppressed the fogging effect, greatly improved the clarity and brightness of the photos, and satisfied the daily selfies, Video calls, and other usage requirements.

Transparency and display itself are contradictory, and the “partial” of either party will make the off-screen camera solution impossible.

In order to solve this challenge and achieve the best balance between the two, Visionox’s Flexible AMOLED  through a special pixel arrangement to significantly weaken the boundary between the main and auxiliary screen areas due to differences in transparency, resolution, etc., allowing the edges of the main and auxiliary screens to transition It is more natural and realizes the synchronization of the main and auxiliary screen display through an innovative driving method.

In addition, Visionox’s PMOLED also makes the main and auxiliary screens more natural in appearance. Through the application of the new OLED device, the brightness difference, color gamut difference, and viewing angle difference between the transparent sub-screen and the main screen are eliminated, and the display consistency of the entire screen is intuitively improved, bringing a more uniform and comprehensive vision.

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
