Description
本創作係有關於一種指紋檢測裝置，特別是關於一種結合在一顯示器上方的薄型光學指紋檢測裝置。The present invention relates to a fingerprint detection device, and more particularly to a thin optical fingerprint detection device combined above a display.
隨著手機技術的推陳出新及手機用戶需求的不斷提高，為了達到更佳的用戶體驗，增加手機螢幕面積占比，乃至全面屏已成為智慧終端機發展的一大趨勢。但是在傳統的電容式指紋識別架構中，由於電容檢測並無法穿透較厚玻璃，故其仍無法完成去除實體Home(還回原位)鍵的任務。With the development of new mobile phone technology and the continuous increase of mobile phone users' needs, in order to achieve a better user experience, increasing the proportion of mobile phone screen area, and even the full screen has become a major trend in the development of smart terminals. However, in the traditional capacitive fingerprint recognition architecture, since the capacitance detection cannot penetrate the thicker glass, it still cannot complete the task of removing the physical home (return to original position) key.
為去除實體Home鍵，習知已有將光學指紋識別模組置於螢幕下方，以針對螢幕上的特定指紋輸入區域進行光學指紋識別的技術方案。請參照圖1，其為一習知光學指紋識別裝置的示意圖。如圖1所示，該習知光學指紋識別裝置具有一玻璃蓋板11、位於玻璃蓋板11下方之一顯示器12，以及位於顯示器12下方之一光學指紋檢測模組13。在此架構下，顯示器12必須能夠透光，光學指紋檢測模組13才能夠對玻璃蓋板11上表面的指紋輸入區域進行一指紋識別作業。In order to remove the physical Home button, it is known that there is a technical solution for placing an optical fingerprint recognition module under the screen to perform optical fingerprint recognition on a specific fingerprint input area on the screen. Please refer to FIG. 1, which is a schematic diagram of a conventional optical fingerprint recognition device. As shown in FIG. 1, the conventional optical fingerprint identification device has a glass cover 11, a display 12 located below the glass cover 11, and an optical fingerprint detection module 13 located below the display 12. Under this architecture, the display 12 must be capable of transmitting light, and the optical fingerprint detection module 13 can perform a fingerprint recognition operation on the fingerprint input area on the upper surface of the glass cover 11.
然而，由於傳統的LCD(liquid crystal display；液晶顯示器)顯示幕係利用背光及偏光片等原理進行顯示，為了避免背光洩露，其非顯示部分一般係由一黑色矩陣進行遮蓋，因而使其無法滿足光學指紋檢測模組13的透光要求，也就無法用以實現屏下指紋識別的技術方案。However, the traditional LCD (liquid crystal display) display screen uses the backlight and polarizer to display. In order to avoid backlight leakage, the non-display part is generally covered by a black matrix, which makes it unsatisfactory. The light transmission requirements of the optical fingerprint detection module 13 cannot be used to implement the technical solution of fingerprint recognition under the screen.
為解決上述問題，習知亦有以OLED (organic light emitting diode；有機發光二極體)顯示幕實現屏下指紋識別的技術方案。請參照圖2，其繪示另一習知光學指紋識別裝置的示意圖。如圖2所示，該習知光學指紋識別裝置具有一玻璃蓋板14、一OLED顯示層15、一光學墊片16、一微透鏡17及一感光陣列18，且玻璃蓋板14設有一有效感應區14a以對一手指19進行一指紋識別作業。In order to solve the above-mentioned problems, there are conventional technical solutions for realizing fingerprint recognition under the screen by using an OLED (organic light emitting diode) display screen. Please refer to FIG. 2, which illustrates a schematic diagram of another conventional optical fingerprint recognition device. As shown in FIG. 2, the conventional optical fingerprint identification device has a glass cover 14, an OLED display layer 15, an optical pad 16, a micro lens 17, and a photosensitive array 18, and the glass cover 14 is provided with an effective The sensing area 14a performs a fingerprint recognition operation on a finger 19.
由於OLED是自發光元件，故可在各OLED顯示像素之間設置縫隙以讓光線透過。為了提高屏下指紋識別效果，該縫隙是越大越好。但是為了提高OLED屏的解析度，該縫隙則是越小越好。因著這個矛盾，屏下指紋識別效果乃受到限制。Since the OLED is a self-luminous element, a gap can be set between each OLED display pixel to allow light to pass through. In order to improve the fingerprint recognition effect under the screen, the larger the gap, the better. However, in order to improve the resolution of the OLED screen, the gap should be as small as possible. Because of this contradiction, the effect of fingerprint recognition under the screen is limited.
另外，目前一般的屏下指紋識別技術方案僅支援在顯示幕上的玻璃蓋板的一特定區域的指紋識別操作。In addition, the current common under-screen fingerprint recognition technology solutions only support fingerprint recognition operations on a specific area of the glass cover on the display screen.
為解決前述的問題，本領域亟需一新穎的光學指紋檢測裝置。In order to solve the foregoing problems, a novel optical fingerprint detection device is urgently needed in the art.

As shown in FIG. 3, the display device with an optical fingerprint detection function includes a glass cover 101, a light source 102, a lens 103, a photosensitive array 104, an air layer 105, and a display 110.
玻璃蓋板101具有相對之一第一表面101a及一第二表面101b，以及相對之一第一側邊101c及一第二側邊101d，其中，玻璃蓋板101具有一第一折射率n1，且該第一表面101a係用以提供至少一指紋辨識區101r。The glass cover 101 has a first surface 101a and a second surface 101b opposite to each other, and a first side 101c and a second side 101d opposite to each other, wherein the glass cover 101 has a first refractive index n1, The first surface 101a is used to provide at least one fingerprint identification area 101r.

The light incident surface 103a faces the second side 101d of the glass cover 101.
感光陣列104係面對透鏡103之出光面103b。The photosensitive array 104 faces the light emitting surface 103b of the lens 103.
空氣層105係藉由至少二間隔件105a而形成於玻璃蓋板101與顯示器110之間以充當一介面層。空氣層105具有相對之一第三表面及一第四表面，其中該第三表面係與玻璃蓋板101之第二表面101b抵接，且空氣層105具有一第二折射率n2(約等於1)，且該第二折射率n2係小於該第一折射率n1以確保在玻璃蓋板101內部行進的光線可在第二表面101b產生全反射。The air layer 105 is formed between the glass cover 101 and the display 110 through at least two spacers 105 a to serve as an interface layer. The air layer 105 has a third surface and a fourth surface opposite to each other, wherein the third surface is in contact with the second surface 101b of the glass cover plate 101, and the air layer 105 has a second refractive index n2 (approximately equal to 1) ), And the second refractive index n2 is smaller than the first refractive index n1 to ensure that the light traveling inside the glass cover plate 101 can be totally reflected on the second surface 101b.
顯示器110，可為一LCD顯示器、一LED顯示器、一電子紙顯示器或一OLED顯示器，係與空氣層105之所述第四表面抵接。The display 110 may be an LCD display, an LED display, an electronic paper display, or an OLED display, and is in contact with the fourth surface of the air layer 105.
本創作的原理在於，當光源102發出的光線通過玻璃蓋板101之第一側邊101c照射到玻璃蓋板101的第一表面101a的一指紋辨識區101r時，該指紋辨識區101r與一手指200之一指紋的多個指紋谷接觸處會使其入射光線反射，然後經多次全反射穿出玻璃蓋板101之第二側邊101d，再通過透鏡103的聚焦作用而照射在感光陣列104上並形成多個亮條紋；而指紋辨識區101r與該指紋的多個指紋脊接觸處則會因接觸面變粗糙而使其入射光線發生漫反射而難以到達感光陣列104，因而在感光陣列104上對應形成多個暗條紋。依此，本創作的光學指紋檢測裝置即可將指紋200的谷、脊資訊轉化為感光陣列104上的明、暗條紋資訊。The principle of this creation is that when the light emitted by the light source 102 shines on a fingerprint recognition area 101r of the first surface 101a of the glass cover 101 through the first side 101c of the glass cover 101, the fingerprint recognition area 101r and a finger The contact points of multiple fingerprint valleys of a fingerprint of 200 will cause the incident light to reflect, and then pass through the second side 101d of the glass cover 101 after multiple total reflections, and then illuminate the photosensitive array 104 through the focusing effect of the lens 103 A plurality of bright stripes are formed thereon; and where the fingerprint recognition area 101r contacts a plurality of fingerprint ridges of the fingerprint, the contact surface becomes rough and diffuse reflection of the incident light makes it difficult to reach the photosensitive array 104. A plurality of dark stripes are formed on the upper surface. Based on this, the optical fingerprint detection device of the present invention can convert the valley and ridge information of the fingerprint 200 into the light and dark stripe information on the photosensitive array 104.
另外，由於光源102發出的光線在玻璃蓋板101內可進行多次全反射，因此，通過改變光源102的入射角度（亦即改變全反射的角度），玻璃蓋板101的第一表面101a即可提供多個指紋檢測區域。也就是說，本創作的光學指紋檢測裝置可藉由改變光源102的光軸方向，使光源102的輸出光線在玻璃蓋板101內以全反射的方式行進而傳輸至感光陣列104，而可在不管顯示器110是否能夠透光的情況下，在玻璃蓋板101的第一表面101a的任一區域進行一指紋識別作業。In addition, since the light emitted by the light source 102 can be totally reflected multiple times in the glass cover 101, by changing the incident angle of the light source 102 (that is, changing the angle of total reflection), the first surface 101a of the glass cover 101 is Multiple fingerprint detection areas are available. In other words, the optical fingerprint detection device of the present invention can change the direction of the optical axis of the light source 102 so that the output light of the light source 102 can be reflected in the glass cover 101 and then transmitted to the photosensitive array 104. Regardless of whether the display 110 can transmit light, a fingerprint recognition operation is performed on any area of the first surface 101 a of the glass cover 101.
