1.56 inche AMOLED Screen

On May 20, China’s leading enterprise Xiaomi released a new and unique design of the smartwatch. This new watch will appear on the stage on May 24. Many people predict that this product will become one of the Chinese most popular products. Why is this conclusion reached?

This watch is equipped with a 1.56 inch AMOLED runway full screen, which is said to have increased the display area by 50%. 326ppi reaches the retina level, with a clear and delicate display effect, and supports dynamic color display. The AMOLED is a highlight: 1.56 inch stunning full-screen touch screen display. According to the official introduction, the new bracelet provides a 1.56 inch AMOLED screen with a resolution of 490*192, which is higher than the 486*152 (the normal pixel of usual watches). It is expected that the screen ratio will be further improved. This long screen with a unique resolution better saves space and production costs. Among them, the specially designed transmissive OCA glue bonding and reflective OLED greatly increase the ratio of sunlight reliability. In addition, the AMOLED screen has another advantage, that is, it does not need a backlight, but uses a self-luminous mode, which consumes less energy. In terms of display effect, the AMOLED screen also has the characteristics of high definition, high brightness, and fast response.


1.56 inch AMOLED Specification:

Body size: 47.4mm × 18.6mm × 12.7mm

Screen size and type: 1.56 inches AMOLED screen

The touch function of this 1.56 inch AMOLED also adopts the most advanced on-cell touch inlay technology, which injects the touch sensor into the middle of the AMOLED film, making it more sensitive to touch and faster to respond. Incell refers to the method of embedding the touch panel function into the OLED pixels, that is, embedding the touch sensor function inside the display screen, which can make the screen lighter and thinner. At the same time, the screen should also be embedded with the supporting touch IC, otherwise, it is easy to cause wrong touch-sensing signal or excessive noise. Therefore, for any display panel manufacturer, the threshold for entering the in-cell touch screen technology is indeed quite high, and it still needs to overcome the difficulty of low yield. At the same time, the defective rate of this technology is high, which is a big pain point for the product. Therefore, it is not easy to achieve a reasonable price.

However, most LCD manufacturers of smart wearable watch devices have enlarged the display to pursue more powerful device configurations. Not many manufacturers can insist on producing small bracelets at reasonable prices. It is worth mentioning that this kind of screen is not unique. Many Chinese LCD&OLED manufacturers can fully copy and produce this process. In the near future, the price may be more favorable. You may wish to look forward to it!
