Wherein, cover the board 1 on the display screen 3, can play good guard action to the display screen 3. It should be noted that, the cover plate 1 generally has a frame area 11, and the frame area 11 is normally black, but it is of course possible to design it in other colors, as long as it is not transparent.
In the electronic device provided by the embodiment of the invention, the ink material or the photoresist material is further coated on at least one surface of the frame area 11 of the cover plate 1. For example, an ink material or a photoresist material is coated on one surface of the frame region 11 of the cover plate 1. For another example, ink material or photoresist material is coated on both surfaces of the frame region 11 of the cover plate 1, respectively. Specifically, the ink material and the photoresist material can play a good role in shielding visible light.
In one embodiment of the present invention, the invisible light emitter 7 employs an infrared invisible light LED, and at the same time, an infrared light transmitting ink material is coated on at least one surface of the rim region 11 of the cover plate 1. The infrared light-transmitting ink material in this example can be used to effectively block visible light, so that the infrared invisible light emitted by the infrared invisible light LED can transmit through the frame region 11 of the cover plate 1.
In the electronic device provided by the embodiment of the present invention, the structure of the display screen 3 is as follows: as shown in fig. 2 and 5, a display panel 33 is included, and a color filter 32 and a polarizer 31 are sequentially laminated on an upper surface of the display panel 33.
