The emergence of mobile devices has not only changed people's living habits, but also the active life represents the beginning of technological innovation.
With the advancement of various technologies, there are more and more intelligent display devices, such as smart phones, smart watches, smart glasses and other end-consumer products, which gradually enter people's lives, and relatively bring more More functionality and convenience.
At present, the global display panel and touch panel related products, the most important estuary is the downstream consumer 3C products. If you look at the size of the display panel, large-size display devices are currently dominated by liquid crystal televisions (LCDs), liquid crystal displays (LCD monitors), and notebook computers (NB).
Small and medium-sized display devices are currently dominated by tablets, smart phones, and wearable devices.
More and more 3C technology display products not only have display panels, but also combine the operation of touch panels. For example, tablet computers and smart phones mainly use touch panels as the main input interface. Or a so-called dual-input interface, such as a notebook computer combined with a touch panel, can choose a traditional keyboard and mouse operation or touch operation. Therefore, it can be seen that the display combined with the touch function can be said to be one of the mainstream trends of many technological products in the future.
The smart wearable device currently seen (Figure 1), the head-to-toe application can be said to be quite diverse, including the smart helmet of the Apache combat helicopter, Google smart glasses, Apple smart watches, Xiaomi smart Bracelets, Nike smart sneakers, etc.

Brand smart watch panel specifications competition
At present, several major smart watch brands in the world, such as Samsung, LG, SONY, ASUS, Motorola, and Apple, have recently launched different sizes. The new flagship smart watch on the display panel.
Since the smart watch is a thin and light wearable display product, it can be observed that the current mainstream display screen size of the product uses a circular or rectangular high-resolution display panel of less than 2 inches.
Samsung's smart watch Gear S, whose display screen is a rectangular rectangular Super AMOLED display panel, and integrates the On-Cell structure of the projected capacitive touch panel with a resolution of 480 & TImes; 360 grade, pixel density is 300ppi. In fact, Samsung has also launched several smart watches before, but it must be used with its own brand of smart phones, and may not actually open the market due to volume and endurance issues.
LG's smart watch G Watch R, its display screen is a 1.3-inch circular P-OLED display panel, also a projected capacitive touch panel with a resolution of 320 & TImes; 320 grade, pixel density of 348ppi.
Sony's smart watch SmartWatch 3, its display screen is a 1.6-inch rectangular LCD display panel, also a projected capacitive touch panel with a resolution of 320 & TImes; 320 grade, pixel density of 283ppi.
ASUS's smart watch ZenWatch has a display screen with a rectangular rectangular AMOLED display panel of 1.63 inches. It is also a projected capacitive touch panel with a resolution of 320 & TImes; 320 levels and a pixel density of 278 ppi.
As for Motorola's smart watch Moto 360, its display screen is a 1.56-inch circular LCD display panel, also a projected capacitive touch panel with a resolution of 320×290 and a pixel density of 277 ppi.
In addition, the Apple Watch, launched by the brand's big Apple in early 2015, Apple Watch, launched two sizes of display screen styles.
The larger display screen is a male model, the display screen is a 1.54 inch rectangular AMOLED display panel, and has a 2.5D curved surface at the edge thereof, and the touch screen is a feedback-type projected capacitive touch panel with resolution. It is about 400×320 grade and has a pixel density of 332ppi.
The smaller display screen is a female model, the display screen is a 1.32 inch rectangular AMOLED display panel, and has a 2.5D surface structure at the edge thereof, and the touch screen is a feedback-type projected capacitive touch panel, and the resolution is estimated. It is 400×320 grade with a pixel density of 386ppi.
Apple Watch can be said that Apple is giving back to the emerging display device products in the hot wearable market. Is there any opportunity for many wearable display devices on the market to drive the demand for another wearable display device? It is subject to subsequent observation. The global brand smart watch panel specifications are compared as shown in Table 1.
Global smart wearable display device shipments estimation statistics, based on the annual basis, observe the global smart wearable display device industry development trend after 2012. Many of the smart wearable display devices currently in development are mainly required to be thin, light and wearable, and to be able to meet specifications such as standby/use time. Therefore, at present, smart wearable display devices are mostly designed as extensions of additional smart mobile display devices, such as smart watches as extension devices for smart phones.
Smart glasses, smart watches, and smart bracelets are among the most popular smart wearable display devices, and they are also one of the growth drivers for the next wave of display panel industry.
It is estimated that the global shipment of intelligent display devices will be approximately 39.11 million units in 2014, with an annual growth rate of approximately 49.8%. In 2015, shipments will reach 65.9 million units, with an annual growth rate of approximately 68.5. %; Looking at shipments in 2016, we will see 198 million units, with an annual growth rate of about 65.3%. A global smart wearable display device shipment forecast chart, as shown in Figure 2.
