With the continuous innovation and progress of technology, there are many advanced electronic products, especially artificial intelligence (AI) and Internet of Things (IoT) electronic products, which are gradually designed to integrate various operations, displays, photography, sensing and control, etc. The functions are centralized and integrated into the same man-machine interface. The man-machine interface is usually a touch panel. Therefore, for the same touch panel, in addition to the basic image display and accepting user operation gestures, it also needs In addition, it provides multiple functions such as status sensing, photography, and control signal reception.

At this time, the outer transparent glass window of the touch panel not only provides sufficient rigidity to protect the display screen, but also needs to meet more design requirements for optical characteristics. For example, on the same glass window, certain areas require Provide high penetration of visible light as much as possible, but some areas want to reduce the penetration of visible light as much as possible, or another area only needs to provide high penetration of infrared light as much as possible, but reduce it as much as possible Visible light penetrability to avoid optical interference, while other areas may wish to completely shield all light, whether it is visible light, infrared light or ultraviolet light.

When these blocks are used as the display area, the clarity and quality of the displayed image can be increased and glare is not easy to produce. Some blocks have proper light-shielding properties, while others are specifically designed to provide high penetration for infrared light to better sense and receive infrared signals, but at the same time, visible light can be filtered out to avoid misoperation.
