Description
本創作係為一種玻璃貼輔助超聲波指紋感應之結構，尤指於玻璃貼與螢幕之間設有一輔助傳遞超聲波指紋感應之傳導膠片，達到訊號不衰弱者。 This creation is a structure of glass-adhesive-assisted ultrasonic fingerprint sensing, especially a conductive film that assists in transmitting ultrasonic fingerprint sensing between the glass sticker and the screen to achieve a signal that is not weak.
查，一般慧型手機或平板電腦、或穿戴式裝置(例如智慧型手錶、手環)等具有螢幕者，尤其是手機更為普遍持有。為了要保護螢幕避免碰撞摩擦而造成破裂或留下刮痕，許多使用者會選擇將該手機螢幕之表面貼覆一手機螢幕保護貼，尤以玻璃貼更普遍、防護能力更佳。且由於消費者的需求，手機螢幕越來越大，甚至為了提升該螢幕的視覺效果及維持更好的手握持感，不但手機機身邊框改採多樣的幾何形狀設計，連螢幕面板邊緣更採用非平面設計(例如：弧形面)與邊框無縫銜接，相對地，玻璃貼之邊周緣亦須設成對應螢幕之形狀，使手機之螢幕邊緣受到全面性的保護，困難的是，玻璃貼要製造完全符合螢幕表面之形狀實非容易，遂有業者開發僅以玻璃貼周緣與螢幕黏結之方式，避免玻璃貼無法與螢幕全面密貼而產生氣泡問題；接著，隨手機之科技發展日新月異，更發展出設置在螢幕下之「超聲波指紋辨識器」，超聲波指紋辨識技術主要是透過按壓螢幕、將聲波反射到螢幕底下的指紋感應器、最後製成3D指紋辨識圖像才得 以解鎖，比起從前的電容式指紋辨識、光學式指紋辨識，超聲波指紋辨識具有不用直接接觸、不受濕手指和微髒污影響、辨識成功率與安全性都大幅提高的優勢，且因「超聲波指紋辨識器」設置在螢幕下不占用螢幕表面區域，大大提升手機之屏占比，乃業者急欲追求之目標，更是受到消費者的青睞；請參閱第1、2圖所示，習知玻璃貼10之構造，係一玻璃膜構件11底部周緣設有一框狀之雙面膠層12，該玻璃膜構件11包含一玻璃層111；一包覆該玻璃層111底面的防爆膜112；一介於該玻璃層111與防爆膜112間之黏膠層113；及一設置於該防爆膜112周緣之框狀印刷層114，且該雙面膠層12頂面黏設於該印刷層114底面，該雙面膠層12底面則貼設於手機1之螢幕2周緣，而該玻璃膜構件11屬硬質之材質，俾使該玻璃膜構件11中央區域與螢幕2之間形成一間隙13，藉此該玻璃貼10毋須與螢幕2全面貼合，避免因公差彼此表面形狀不一致造成產生氣泡之問題；惟上述之玻璃貼10構造，使用者按壓在對應螢幕2之超聲波指紋感應區14之玻璃貼10上時，設置在螢幕2下之超聲波指紋辨識器15發射之超聲波訊號151除須穿透手機1螢幕2之外，尚須穿透一層間隙13(即空氣層)及玻璃膜構件11，因此需要穿透更高的厚度方能將超聲波訊號151從使用者指紋上反射彈回超聲波指紋辨識器15，以對指紋上的所有脊(指紋突起處)和谷(指紋凹下處)進行3D捕捉，但事實上超聲波訊號151的穿透力有限，又眾所皆知聲波之傳遞介質為固態>液態>氣態，該超聲波訊號151通過該間隙13(空氣層)時，已削弱其訊號，如此一來，使用者手指透過該玻璃貼10按壓在該超聲波指紋感應區14位置上欲手機1解鎖時，就會影響到辨識的結果，常發生無法感應解鎖及造成感應上錯誤之問題，此乃亟待改善之問題，對於業者亦為相當之考驗。 Check, general smart phones or tablets, or wearable devices (such as smart watches, bracelets) and other screeners, especially mobile phones are more commonly held. In order to protect the screen from collision and friction, it may cause cracks or scratches. Many users will choose to attach the surface of the screen to a mobile phone screen protector, especially glass stickers are more common and better protection. And because of the needs of consumers, the screen of mobile phones is getting bigger and bigger, and even in order to enhance the visual effect of the screen and maintain a better hand grip, not only the frame of the mobile phone body is changed into a variety of geometric shapes, but also the edge of the screen panel. Non-planar design (for example: curved surface) is seamlessly connected with the frame. In contrast, the edge of the glass sticker must also be set to the shape of the screen, so that the edge of the screen of the mobile phone is comprehensively protected. The difficulty is that the glass It is not easy to make a shape that completely conforms to the surface of the screen. Some manufacturers have developed the method of bonding only the periphery of the glass sticker to the screen, so as to avoid the problem that the glass sticker cannot be completely adhered to the screen, and then the bubble problem arises. Then, with the development of the technology of the mobile phone, the technology is changing with each passing day. The "ultrasonic fingerprint reader" set under the screen has been developed. The ultrasonic fingerprint identification technology is mainly obtained by pressing the screen, reflecting the sound wave to the fingerprint sensor under the screen, and finally making a 3D fingerprint identification image. In order to unlock, compared with the previous capacitive fingerprint identification and optical fingerprint identification, the ultrasonic fingerprint identification has the advantages of no direct contact, no wet finger and slight dirt, and the recognition success rate and safety are greatly improved, and "Ultrasonic fingerprint reader" is set under the screen without occupying the surface area of the screen, which greatly enhances the screen ratio of the mobile phone. It is the target that the industry is eager to pursue, and it is favored by consumers; please refer to Figures 1 and 2, The glass film member 10 is provided with a frame-shaped double-sided adhesive layer 12, the glass film member 11 comprises a glass layer 111; an explosion-proof film 112 covering the bottom surface of the glass layer 111; An adhesive layer 113 between the glass layer 111 and the explosion-proof film 112; and a frame-shaped printing layer 114 disposed on the periphery of the explosion-proof film 112, and the top surface of the double-sided adhesive layer 12 is adhered to the bottom surface of the printing layer 114 The bottom surface of the double-sided adhesive layer 12 is attached to the periphery of the screen 2 of the mobile phone 1. The glass film member 11 is made of a hard material, so that a gap 13 is formed between the central portion of the glass film member 11 and the screen 2. This glass sticker 10 It is fully integrated with the screen 2 to avoid the problem of bubble generation due to the inconsistency of the surface shapes of the tolerances; however, the above-mentioned glass patch 10 structure is set when the user presses the glass sticker 10 corresponding to the ultrasonic fingerprint sensing area 14 of the screen 2 The ultrasonic signal 151 emitted by the ultrasonic fingerprint reader 15 under the screen 2 has to penetrate the gap 1 (ie, the air layer) and the glass film member 11 in addition to the screen 2 of the mobile phone 1, so that a higher penetration is required. The thickness can reflect the ultrasonic signal 151 from the fingerprint of the user back to the ultrasonic fingerprint reader 15 to capture 3D of all the ridges (fingerprint protrusions) and valleys (fingerprint depressions) on the fingerprint, but in fact the ultrasonic signals The penetration force of 151 is limited, and it is well known that the transmission medium of sound waves is solid>liquid>gaseous state. When the ultrasonic signal 151 passes through the gap 13 (air layer), the signal is weakened, so that the user's finger penetrates. When the glass sticker 10 is pressed at the position of the ultrasonic fingerprint sensing area 14 to unlock the mobile phone 1, the result of the identification is affected, and the problem that the inability to sense the unlocking and the sensing error often occurs is caused. Urgent problem improvement for the industry as Zheyi quite a test.
