Guangzhou Shiyuan's "smart mirror" makes a stunning debut in smart homes

In recent years, the domestic smart home industry has gradually heated up driven by the development of 5G, the Internet of Things and AI technologies, and its technology, functions and market have undergone new changes. At the Shanghai International Smart Home Exhibition not long ago, MAXHUB of Guangzhou Vision Technology demonstrated a central control terminal - smart mirror, which integrates other innovative functions while keeping the mirror clear. When the user is ready to go out, he can automatically obtain weather, traffic, news, schedule and other information from the mirror, and centrally control other devices in the home through touch and voice control.

In the design concept of smart home, a smart mirror is a mirror that can display patterns, videos, and touch operations. The protective cover is mirrored as a whole, and a small area is set as a touch display area. The back side corresponds to the touch display area and is bonded with a capacitive touch layer. However, its production cost is high, and it is not conducive to customers to freely match protective covers of different sizes. To address this problem, there is a structure on the market that does not fit the protective cover and the touch layer. A circle of adhesive layer is set along the touch layer to bond the protective cover, and it can be reused to reduce costs. However, this structure also has many problems. It will cause the protective cover to contact the touch layer during touch operation, resulting in rainbow patterns, affecting the appearance and user experience.

To this end, Guangzhou Shiyuan filed an invention patent entitled "Touch screen, display device and smart mirror" (application number: 201911261555.0) on December 10, 2019. The applicants are Guangzhou Shiyuan Electronic Technology and Guangzhou Shirui Electronic Technology Co., Ltd.

Figure 1 Display module schematic

FIG1 is a schematic diagram of a display module proposed in this invention, wherein the touch screen 1 on the top includes a cover plate 11 and a touch layer 12 on one side, and a first adhesive layer 13 is provided in an annular manner along the periphery of the touch layer 12 on the side surface to bond with the cover plate 11, and a light-transmitting isolation layer is fixed on the cover plate 11 or the touch layer 12. In addition, the insulating points 14 are distributed throughout the area enclosed by the first adhesive layer 13, and are evenly arranged in the area within the entire first adhesive layer 13, so that the touch layer 12 can be completely isolated, ensuring that no rainbow pattern will occur when pressing any position of the cover plate 11 corresponding to the touch layer 12.

The insulating dots 14 can be formed on the cover plate 11 by printing, thereby reducing the difficulty of operation and increasing production efficiency. Since the insulating dots 14 are insulating ink, they can not only meet the requirements of printing and forming the insulating dots 14, but also utilize their own insulating and non-stick effects to meet the requirements of easy separation of the cover plate 11 and the touch layer 12. In order to make the mirror surface more beautiful, the diameter of the insulating dots is less than 0.2 mm, and the height is not greater than the thickness of the first adhesive layer 13. At the same time, the spacing between the insulating dots is not less than 1 mm. The arrangement pattern of the insulating dots 14 with larger spacing can not only meet the basic isolation function of the insulating dots 14 and effectively prevent the rainbow pattern phenomenon, but also be more conducive to the separation of the cover plate 11 from the touch layer 12. At the same time, it can also reduce the visibility of the insulating dots 14 on the touch operation side of the cover plate 11, so that the appearance display effect is better.

Figure 2 shows another structural diagram of the module

FIG2 is another display module structure proposed by the invention, in which the insulating point 14 is arranged on the touch layer 12 and is spaced apart from the cover plate 11. The light transmittance of the insulating point 14 is greater than that of the cover plate 11. By using transparent insulating ink or insulating glue, the influence of the setting of the insulating point 14 on the display effect can be further reduced. In addition, the thickness of the first adhesive layer 13 is less than 1 mm, so that the gap between the cover plate 11 and the touch layer 12 is very small, thereby reducing the height of the insulating point 14, which can effectively solve the rainbow pattern phenomenon, ensure the display effect, and reduce the manufacturing cost.

In short, this invention of Guangzhou Shiyuan mainly provides a touch screen and display device, which can be used in the display modules of electronic devices such as smart interactive tablets and smart mirrors. The cover plate and the touch layer are easy to separate, the cost is low, and no rainbow pattern phenomenon occurs. It has better display effects and greatly improves the user experience.

In fact, "smart screens" can be seen everywhere in daily life, such as mobile phones, tablets, computers, etc. Guangzhou Shiyuan's MAXHUB smart mirror product uses its own technology and market advantages, takes advantage of the trend of smart home, and combines common household devices such as lighting and home appliances to display this "magic mirror", making people's daily life more portable.
