Front panel for touch panel, display device provided with the same, and integrated sensor substrate of front panel for touch panel and touch panel sensor

摘要

Infrared communication of the infrared communication unit provided below the frame part of the front panel of the touch panel sensor is realized without providing an infrared communication window having an infrared transmission film in the frame part. By forming the frame portion of the front plate from a material that absorbs visible light and transmits infrared rays, it is unnecessary to conceal the wiring and to provide an infrared communication window in the frame portion. As a result, the number of steps and the manufacturing cost are prevented from increasing, and the inconvenience due to the level difference caused by forming the infrared transmission film on the frame portion is also eliminated.
