Fifteen years ago, at the time when the CRT was in its midst, liquid crystal and plasma were born and a major change in color TV technology began. Fifteen years later, on the occasion of the popularity of LCD TVs, a series of display technologies such as OLED and quantum TV emerged. A new round of color TV technology came to the fore, and even many color TV companies were fascinated by the layout of next-generation display technologies. road. However, for the future leader in the display technology OLED camp, Skyworth, the future development of color TV technology has long been predicted. In the display of the key nodes of technological change, Skyworth has planned to own the right to speak in advance and promote the competition between color TV brands and enterprises. To the finest battlefield.
This is a pre-judgment related to "life and death"
All along, in the color TV industry, from early CRT TVs to LCD TVs to OLED organic TVs, color TV technology is constantly being updated and upgraded. However, each technological change is not just a simple visual revolution, but a game concerning the future direction of the company and the brand's life and death. Once the wrong team is located and the pre-judgment is wrong, the price paid by the company may be the stage of exiting the color TV. . Changhong dream broken plasma, Matsushita tycoon Bao finally abandoned the camp for many years of plasma front, are the lesson.
Like LCD and plasma that year, 2017 was a year for OLEDs and quantum dots. However, as technology and products mature, more and more companies and experts are standing in the OLED camp. With the addition of Sony, Skyworth, LG, Changhong, Konka, Philips, etc. have formed OLED TV camps. OLED display technology has the advantage of self-illumination. OLEDs have obvious advantages in terms of flexibility, contrast, full-color, light efficiency, refresh rate, and viewing angle compared to ordinary LCD TVs and Quantum-dot TVs. For example, Skyworth's latest Wallpaper OLED TV with thin walls, LCD and quantum dot display technology have not been implemented. As the analogy of Liu Buchen, a senior observer of the home appliance industry, OLEDs and quantum dots are all surpassing liquid crystal display technology. However, the degree of transcendence is different. OLED's transcendence in LCD is like car's surpassing the carriage, and quantum dot's transcendence in LCD is even more. Like a carriage overtaking another carriage.
This game related to the company's future color TV technology, who can truly grasp the right to speak in advance, who can win. In the OLED camp, color TV manufacturers represented by Skyworth have spared no effort in OLED layout. As early as 2013, Skyworth launched the first OLED TV for “Little Chopperâ€, followed by mass production of 4K OLED TV, and Skyworth and BOE with Hi-Tech and Hi-Site released China’s first self-developed OLED TV in 2016, and launched subversive TV recently. In the form of Wallpaper OLED TVs, Skyworth is playing an increasingly important role in the television industry in China and even in the world. Because this technical game is not only a forward-looking vision, but also preemptive action.
Ye Zhiqiu, OLED took the lead in the mobile phone industry
In the contest between OLED and quantum dots, Liu Buying raised an interesting question: In the quantum dot camp, quantum dots are excellent enough to kill OLEDs. Since QDs are so outstanding, why mobile phone companies choose to upgrade their screens? Is OLED instead of quantum dots?
Mobile phone manufacturers have chosen OLED screens to replace traditional LCD screens, which has given the public an extremely strong signal: OLED is better than LCD. The layout of OLED in the mobile phone industry also reveals the fact that OLED is the right choice. Global AMOLED mobile phone panel shipments reached 370 million units in 2016, a significant increase of 41.2% compared to 2015. In addition to Samsung, OPPO, Vivo, Huawei, Jinli, Meizu and Lenovo contributed 26% of the top ten brands in China. Share. At the same time, Apple's new products will adopt OLED screens this year, or promote the outbreak of OLED applications in the mobile phone field.
Executive Director/CEO of Skyworth Digital Holdings Co., Ltd., President of Skyworth Group, and Mr. Liu Zhizhi, President of Shenzhen Skyworth-RGB Electronics Co., Ltd. had a pre-judgment: “More than ten years ago, the mobile phone industry was in full swing with the LCD screen, and later the LCD TV put the CRT TV. It is sinking. Now, the mobile phone industry is vigorously promoting OLED screens, so the next step is to replace LCD TVs with OLED TVs."
Even more interesting is that in the future OLED field display technology intensive development, Skyworth has never stopped in the LCD TV technology improvement, Skyworth recently developed a "solid color technology" that can achieve the greatest degree of reduction of true color, in color control Pure color technology is slightly better than quantum dots. Quantum dots with liquid crystal color improvement as the main battlefield and the solid color technology have launched a fierce battle. An improved liquid crystal technology will be able to overcome the quantum dot technology. Why does quantum dots compete for future display technology?
Nowadays, the television industry is at the crossroads of display technology upgrades, left or right? To OLED or vector sub points? The forward-looking and pre-judgment companies represented by Skyworth have already laid out in advance and strive to gain the right to speak independently. But the real test is whether companies can make breakthroughs in the next generation of display technology and go further. Continuous innovation ability and the courage to change are still the keys that cannot be ignored. The story has already begun and the answer will be revealed by time.

Eight-layer PCB can be used to add two additional layers, or two planes can be added to improve EMC performance. Most eight-layer circuit boards are superimposed to improve EMC performance, rather than adding additional wiring layers. Compared with 6-layer circuit boards, the cost increase percentage of 8-layer PCB is less than that of 4-layer PCB to 6-layer PCB. Therefore, in order to improve EMC performance, the cost increase is reasonable. Therefore, most 8-layer boards consist of four wiring layers and four planes.
In short, 8 layer PCB are usually used to improve the EMC performance of circuit boards, rather than increasing the number of layers.
No matter how you decide on the stack layer, it is not recommended to use an 8-layer PCB board with six wiring layers. If you need six routing layers, you should use a 10 Layer PCB board. Therefore, the 8-layer board can be regarded as the six-layer board with the best EMC performance.
All signal layers are adjacent to the plane, and all layers are tightly coupled. High-speed signals are buried between planes, so planes provide shielding to reduce the transmission of these signals. In addition, the circuit board uses multiple grounding layers to reduce the grounding impedance.

8 Layer PCB - Stackup & Cost & Prototype manufacture
What is 8 layer PCB?
The 8 layer PCB is a circuit board with 8 layers that are stacked firmly together with predefined and dependable mutual connections between the layers. Structure of eight layer PCB is more complicated. Nowadays, PCBs frequently have 8 to 12 layers or more, and electronics engineers know that designing for so many layers requires a well-configured layer stack.
8-layer printed circuit boards are usually installed in compact equipment with strict spacing requirements, such as notebook computer motherboard, communication backplane, wearable watches, etc. Because of its complexity and high manufacturing costs, your 8-layer PCB manufacturing should be made by reliable and experienced manufacturers. Jinghongyi PCB has been specially targeting high-end PCB manufacturing and assembly services for 8 years, providing high-quality products and services for various customers. Our advanced production line and fast response team will keep you comfortable and reassured, without any trouble, you can rest assured to place the order with us.

Eight-layer PCB can be used to add two additional layers, or two planes can be added to improve EMC performance. Most eight-layer circuit boards are superimposed to improve EMC performance, rather than adding additional wiring layers. Compared with 6-layer circuit boards, the cost increase percentage of 8-layer PCB is less than that of 4-layer PCB to 6-layer PCB. Therefore, in order to improve EMC performance, the cost increase is reasonable. Therefore, most 8-layer boards consist of four wiring layers and four planes.
