The screen size of JDI for mobile phones and tablet products ranges from 4.3 inches to 10. 1 inch, and the resolution gradually rises from 720p to 3840×2 160, which is called "4K2K".
The four columns between the screen size and the number of pixels represent several display technologies of JDI, namely Pixel Eyes(PE), WhiteMagic(WM), wide Color gamut (color) and IPS-NEO(NEO).
With the characteristics of low power consumption and high image quality, JDI is widely used in today's smart phones, and it is also an industry giant alongside Sharp in the Japanese market.
In addition to Japanese models, domestic brands also have flagship products such as hammer, Xiaomi and OPPO to choose JDI screens. After the completion of the new factory, the production capacity of JDI will also be greatly improved, and the intention to further seize the market is also very obvious.
Sharp, with a history of one hundred years, has always enjoyed the reputation of "the father of LCD". In the field of mobile phone screens, Sharp is also a big brother. On many flagship mobile phones, we can see the figure of Sharp screen.
Speaking of Sharp screen, we have to mention two influential patents: ASV(Advance Super View) technology and IGZO(indium galaxy zinc oxide) technology.
ASV technology is not a panel technology, but a technology to improve image quality. It mainly reduces the reflection of the LCD screen by reducing the spacing between particles on the LCD panel, increasing the aperture of liquid crystal particles, and adjusting the arrangement of liquid crystal particles as a whole, thus increasing the brightness, viewing angle and contrast.
IGZO is the abbreviation of "indium gallium zinc oxide", which is a semiconductor material used to produce liquid crystal displays. Compared with silicon-based chips, this material can provide up to twice the battery life and clearer images, and can also improve the touch screen sensitivity of smartphones and tablets by more than five times.
Although in the fierce screen competition in recent years, the technical advantages of ASV are gradually losing. Although IGZO technology has great potential, it is still immature. However, the overall performance of Sharp screen is excellent, and it is still the first choice of many mobile phone manufacturers.
abstract
In recent years, the fierce competition in the mobile phone industry has also driven the competition in the mobile phone screen industry. For mobile phone screen manufacturers, only by continuously developing and producing screens with better image quality, lower power consumption and better cost control can they be in an advantageous position in this process and win the favor of more mobile phone manufacturers.
