為使 貴審查委員能進一步瞭解本發明之結構、特徵及其目的，茲附以圖式及較佳具體實施例之詳細說明如後。In order to enable your reviewers to further understand the structure, characteristics, and purpose of the present invention, drawings and detailed descriptions of the preferred embodiments are attached below.
為解決先前技術的問題，本發明提出一指紋檢測架構，其係通過在一玻璃蓋板內使入射光線進行多次全反射，而使整個顯示幕的多個區域皆可做為一指紋識別區。請參照圖1，其繪示本發明之一光學指紋檢測裝置之側視圖。如圖1所示，該習知光學指紋檢測裝置包括一玻璃蓋板101、一光源102、一透鏡103及一感光陣列104。In order to solve the problems of the prior art, the present invention proposes a fingerprint detection architecture, which makes multiple areas of the entire display screen can be used as a fingerprint identification area by totally reflecting the incident light in a glass cover. . Please refer to FIG. 1, which illustrates a side view of an optical fingerprint detection device according to the present invention. As shown in FIG. 1, the conventional optical fingerprint detection device includes a glass cover 101, a light source 102, a lens 103, and a photosensitive array 104.
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 first surface 101a is used to provide at least one fingerprint identification. District 101r.
光源102係位於玻璃蓋板101之第一側邊101c。The light source 102 is located on the first side 101c of the glass cover 101.
透鏡103具有一入光面103a及一出光面103b，入光面103a係面對玻璃蓋板101之第二側邊101d。The lens 103 has a light incident surface 103a and a light emitting surface 103b. The light incident surface 103a faces the second side 101d of the glass cover plate 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.
圖1之光學指紋檢測裝置的原理在於：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的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，該光學指紋檢測裝置即可將該指紋的谷、脊資訊轉化為感光陣列104上的明、暗條紋資訊。The principle of the optical fingerprint detection device of FIG. 1 is that when light emitted from the light source 102 is irradiated to 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 identification The area 101r is in contact with multiple fingerprint valleys of a fingerprint of a finger 200 to reflect incident light, and then passes through the second side 101d of the glass cover 101 through multiple total reflections, and then through the focusing effect of the lens 103, Irradiated on the photosensitive array 104 and formed a plurality of bright stripes; and where the fingerprint recognition area 101r is in contact with multiple 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, Therefore, a plurality of dark stripes are correspondingly formed on the photosensitive array 104. According to this, the optical fingerprint detection device can convert the valley and ridge information of the fingerprint 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，該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，而可在一顯示幕上方的多個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. That is, the optical fingerprint detection device 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 transmitted to the photosensitive array 104. A plurality of areas above the screen perform a fingerprint recognition operation.
另外，隨著技術的進步與發展，手機顯示幕要求的尺寸越來越大，本發明進一步提出另一光學指紋檢測裝置，其係通過設置多組“光源-透鏡-感光陣列”，以將多個指紋檢測區域聯通而覆蓋整個顯示幕，達到全屏指紋檢測的效果。請參照圖2，其繪示本發明之另一光學指紋檢測裝置之俯視圖。如圖2所示，該光學指紋檢測裝置包括一玻璃蓋板101、4個光源102、4個透鏡103及4個感光陣列104。In addition, with the advancement and development of technology, the size required for the display screen of mobile phones is getting larger and larger. The present invention further proposes another optical fingerprint detection device, which is provided with multiple sets of "light source-lens-photosensitive array" in Each fingerprint detection area is connected to cover the entire display screen, achieving the effect of full-screen fingerprint detection. Please refer to FIG. 2, which illustrates a top view of another optical fingerprint detection device of the present invention. As shown in FIG. 2, the optical fingerprint detection device includes a glass cover 101, four light sources 102, four lenses 103, and four photosensitive arrays 104.
玻璃蓋板101具有相對之一第一表面101a及一第二表面(未示於圖中)，以及相對之一第一側邊101c及一第二側邊101d，其中第一表面101a係用以提供複數個指紋辨識區。The glass cover plate 101 has a first surface 101a and a second surface (not shown) opposite to each other, and a first side 101c and a second side 101d opposite to each other. The first surface 101a is used for Provide multiple fingerprint identification areas.
4個光源102係位於玻璃蓋板101之第一側邊101c。The four light sources 102 are located on the first side 101c of the glass cover 101.
4個透鏡103係各與一光源102對應且各具有一入光面103a及一出光面103b，入光面103a係面對玻璃蓋板101之第二側邊101d。Each of the four lenses 103 corresponds to a light source 102 and has a light incident surface 103a and a light emitting surface 103b. The light incident surface 103a faces the second side 101d of the glass cover plate 101.
4個感光陣列104係各面對一透鏡103之出光面103b。Each of the four photosensitive arrays 104 faces a light emitting surface 103b of a lens 103.
於操作時，該光學指紋檢測裝置可依序或同時開啟各光源102，以使各光源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一對應的感光陣列104，而可在一顯示幕上方的任一區域進行一指紋識別作業，從而提供一全屏光學指紋識別功能。During operation, the optical fingerprint detection device may turn on each light source 102 sequentially or simultaneously, so that the output light of each light source 102 travels in the glass cover 101 in a total reflection manner and then is transmitted to a corresponding photosensitive array 104, and A fingerprint recognition operation can be performed in any area above a display screen, thereby providing a full-screen optical fingerprint recognition function.
然而，隨著手機顯示幕的需求尺寸越來越大，為了覆蓋更大尺寸的顯示幕，需要的“光源-透鏡-感光陣列”就越來越多，致使對指紋資訊的檢測掃描時間變得更長，而所產生的功耗也因而成倍增加。在另一方面，就通常的指紋辨識應用而言，整個顯示幕上待檢測的手指個數不會超過10個，且事實上，在大多數情況下只有一個手指需對其進行辨識。在此情況下，盲目的掃描操作就顯得很沒效率而有很大的改進空間。However, with the increasing demand for the size of mobile phone display screens, in order to cover larger display screens, more and more "light sources-lenses-photosensitive arrays" are needed, resulting in the scanning time for fingerprint information detection and scanning. Longer, and the resulting power consumption has increased exponentially. On the other hand, in the case of general fingerprint recognition applications, the number of fingers to be detected on the entire display screen will not exceed 10, and in fact, in most cases, only one finger needs to be recognized. In this case, the blind scanning operation is very inefficient and has a lot of room for improvement.
為解決上述的問題，本發明進一步提出一智能型的全屏指紋檢測方法。請參照圖3，其繪示本發明之全屏指紋檢測方法之一實施例的流程圖。To solve the above problems, the present invention further proposes an intelligent full-screen fingerprint detection method.

在步驟b中所採用的所述光學指紋檢測電路包括一光源、一透鏡及一感光陣列，且當所述光學指紋檢測電路被啟動時，其係藉由使該光源的輸出光線在該玻璃蓋板內以全反射的方式傳播而照射到該玻璃蓋板上的一所述手指按壓位置，從而產生承載一所述指紋的資訊的輸出光線，並使該輸出光線經該透鏡聚焦後照射該感光陣列。在一可能的實施例中，該光源係一可改變輸出光軸方向的光源。The optical fingerprint detection circuit used in step b includes a light source, a lens, and a photosensitive array, and when the optical fingerprint detection circuit is activated, it causes the output light of the light source to pass through the glass cover. The plate propagates in a total reflection manner and irradiates a finger pressing position on the glass cover plate, thereby generating an output light carrying information of the fingerprint, and making the output light focused by the lens and irradiating the light sensitivity. Array. In a possible embodiment, the light source is a light source capable of changing the direction of the output optical axis.

Please refer to FIG. 4, which illustrates a top view of an embodiment of a full-screen fingerprint detection system of the present invention. As shown in FIG. 4, the full-screen fingerprint detection system includes a glass cover 101, 4 light sources 102, 4 lenses 103, 4 photosensitive arrays 104, and a touch detection circuit (not shown) located below the glass cover 101. In the figure). The touch detection circuit may be a resistive touch detection circuit, a capacitive touch detection circuit, a pressure touch detection circuit or an sonic touch detection circuit. Since these touch detection circuits are all known technologies, they are not described in detail here.

The first surface 101a is used for Provide multiple fingerprint identification areas.

當該觸控偵測電路偵測到玻璃蓋板101上的一手指按壓位置(如圖4中所示)而致使編號為2的光學指紋檢測電路被啟動時，該編號為2的光學指紋檢測電路會藉由使編號為2的光源102的輸出光線在玻璃蓋板101內以全反射的方式傳播而照射到玻璃蓋板101上的所述手指按壓位置，從而產生承載一指紋資訊的輸出光線，並使該輸出光線經編號為2的透鏡103聚焦後照射編號為2的感光陣列。When the touch detection circuit detects a finger pressing position on the glass cover 101 (as shown in FIG. 4) and the optical fingerprint detection circuit number 2 is activated, the optical fingerprint detection number 2 is activated.
