Abstract
Description
本新型創作是有關於一種電子裝置,且特別是有關於一種具有指紋感測模組的電子裝置。The present invention relates to an electronic device, and particularly to an electronic device with a fingerprint sensing module.
在傳統具有超薄指紋模組的電子裝置中,在進行指紋訊號感測時,此中框的結構容易反射部分光線,造成這些光線進入感測模組,而使得這些光線與指紋訊號同時成像。這樣一來,將使得所感測到的指紋訊號出現雜訊。因此,如何避免因中框的結構而造成光線反射回感測模組,是本領域需致力於行的目標。In traditional electronic devices with ultra-thin fingerprint modules, when fingerprint signal sensing is performed, the structure of the middle frame is likely to reflect some light, causing these lights to enter the sensing module, so that these lights and fingerprint signals are simultaneously imaged. In this way, noise will appear in the sensed fingerprint signal. Therefore, how to avoid the reflection of light back to the sensing module due to the structure of the middle frame is a goal in this field.
本新型創作提供一種電子裝置,可避免反射雜散光至指紋感測模組,從而避免指紋感測模組感測出雜訊光訊號而有效提升指紋感測效果。The present invention provides an electronic device that can avoid reflecting stray light to the fingerprint sensing module, thereby preventing the fingerprint sensing module from sensing noise light signals and effectively improving the fingerprint sensing effect.
本新型創作提供一種電子裝置,包括指紋感測模組、顯示面板以及中框。指紋感測模組適於感測由手指所反射的感測光束。顯示面板配置於指紋感測模組,適於提供照明光束至手指以反射出感測光束。中框配置於指紋感測模組與顯示面板之間。中框具有相對的第一面、第二面以及入光口。第一面朝向顯示面板,第二面朝向指紋感測模組。感測光束通過入光口以傳遞至指紋感測模組,其中第一面包括朝向第二面凹下的環形凹槽,環形凹槽與入光口具有一距離。The present invention provides an electronic device including a fingerprint sensing module, a display panel and a middle frame. The fingerprint sensing module is suitable for sensing the sensing light beam reflected by the finger. The display panel is configured in the fingerprint sensing module, and is suitable for providing an illumination beam to the finger to reflect the sensing beam. The middle frame is arranged between the fingerprint sensing module and the display panel. The middle frame has a first surface, a second surface, and a light entrance. The first side faces the display panel, and the second side faces the fingerprint sensing module. The sensing beam passes through the light entrance to be transmitted to the fingerprint sensing module, wherein the first surface includes an annular groove recessed toward the second surface, and the annular groove has a distance from the light entrance.
基於上述,在本新型創作的電子裝置中,藉由環形凹槽設計,使得中框可減少反射雜散光至指紋感測模組,從而避免指紋感測模組感測出雜訊光訊號而有效提升指紋感測效果。Based on the above, in the electronic device created by the present invention, the annular groove design enables the middle frame to reduce the reflection of stray light to the fingerprint sensor module, thereby preventing the fingerprint sensor module from sensing the noise light signal and effectively Improve fingerprint sensing effect.
為讓本新型創作的上述特徵和優點能更明顯易懂,下文特舉實施例,並配合所附圖式作詳細說明如下。In order to make the above-mentioned features and advantages of the new creation more obvious and understandable, the following embodiments are specially cited, and the accompanying drawings are described in detail as follows.
請參考圖1。本實施例提供一種電子裝置10,包括指紋感測模組50、顯示面板60以及中框100。顯示面板60適於提供照明光束L1至手指20以反射出感測光束L2,而指紋感測模組50配置於顯示面板60下方,適於感測由手指20所反射的感測光束L2。換句話說,本實施例的電子裝置10為屏下指紋辨識裝置,例如是智慧型手機、平板電腦、筆記型電腦或觸控型顯示裝置等,本新型創作並不限於此。在本實施例中,指紋感測模組50為超薄結構,其厚度僅約300微米,故可應用於薄型的電子裝置10中。Please refer to Figure 1. This embodiment provides an
在本實施例中,指紋感測模組50包括電路板52、感光元件54以及光學模組56。電路板52用以承載感光元件54並供應電源。電路板52例如為軟性電路板,且感光元件54以黏著方式固定於電路板52上。舉例而言,指紋感測模組50還可包括黏著膠層,連接於感光元件54的底側與電路板52,但本新型創作並不限於此。此外,在一些實施例中,感光元件54另可以封裝的方式藉由封裝材料加強感光元件54在電路板52上的結構強度。In this embodiment, the
感光元件54配置於電路板52上,且具有感光面。舉例而言,感光元件54包括多個感測單元。感光元件54例如是互補式金氧半導體(complementary metal oxide semiconductor, CMOS)影像感測器,而感測單元則為這些影像感測晶器中的感測畫素。然而,在其他實施例中,感光元件54也可以是電荷耦合元件(charge coupled device, CCD)等影像感測器,本新型創作並不限制指紋感測模組50中感光元件54的種類。在一些實施例中,感光元件54上可配置有濾光片或濾光材料層以濾除由外部朝感光元件54傳遞的紅外光,進而提高感測效果。The
光學模組56配置於感光元件54上,由至少一透鏡或其他光學元件所組成。舉例而言,在本實施例中,光學模組56例如包括具有屈光度的一或多個光學鏡片的組合,例如包括雙凹透鏡、雙凸透鏡、凹凸透鏡、凸凹透鏡、平凸透鏡以及平凹透鏡等非平面鏡片的各種組合。於一實施例中,光學模組56還可以包括陣列透鏡,以提高傳遞入射光線的均勻度。本新型創作對光學模組56的型態及其種類並不加以限制。The
顯示面板60配置於指紋感測模組50。在本實施例中,顯示面板60例如為有機發光二極體(organic light-emitting diode, OLED)顯示面板。然而,在其他實施例中,顯示面板60亦可以選擇液晶顯示面板或其他適當的顯示面板,本新型創作並不限於此。The
請同時參考圖1至圖3。中框100配置於指紋感測模組50與顯示面板60之間,用以限制或校準指紋感測模組50的位置以及用以承載顯示面板60。中框100具有相對的第一面S1、第二面S2以及入光口P,其中第一面S1朝向顯示面板60,而第二面S2朝向指紋感測模組50。因此,感測光束L2由朝顯示面板60的一側傳遞通過中框100的入光口P,進而傳遞至指紋感測模組50。在本實施例中,光學模組56位於入光口P中,但本新型創作並不限於此。Please refer to Figures 1 to 3 at the same time. The
在本實施例中,中框100的第一面S1包括朝向第二面S2凹下的環形凹槽G,而環形凹槽G與入光口P具有一距離D。第一面S1與第二面S2的大部分為平坦水平表面,而少部分具有其他結構,如上述所提的環形凹槽G。由於環形凹槽G與入光口P具有距離D,故當雜散光L3傳遞至環形凹槽G時,將不易被反射至指紋感測模組50。在不同的實施例中,距離D處可設計有不同斜率的斜面,以降低雜散光L3反射進入指紋感測模組50的機率。因此,當雜散光L3朝中框100傳遞時,雜散光L3不會因傳遞至中框100的表面而直接或間接反射傳遞至指紋感測模組50。如此一來,本實施例所設計的中框100可避免反射雜散光L3至指紋感測模組50,從而避免指紋感測模組50感測出雜訊光訊號而有效提升指紋感測效果。在一些實施例中,電子裝置10還可以包括黑色環形件,配置於環形凹槽G,用以吸收雜散光L3以及增加手指20按壓時的支撐性,但本新型創作並不限於此。In this embodiment, the first surface S1 of the
詳細而言,中框100的第一面S1具有第一環形斜面S11,位於環形凹槽G與入光口P之間。在本實施例中,第一環形斜面S11與水平參考平面具有第一夾角B1,此第一夾角B1大於30度。如此一來,較鄰近中心處的雜散光L3(即傳遞至環形凹槽G與入光口P之間的光線)可藉由第一環形斜面S11而反射遠離入光口P,進而避免藉由中框100而反射傳遞至指紋感測模組50。In detail, the first surface S1 of the
在本實施例中,中框100的第一面S1還具有第二環形斜面S12,位於環形凹槽G與第一環形斜面S11之間。換句話說,環形凹槽G的其中一部分由第二環形斜面S12所構成。在本實施例中,第二環形斜面S1與水平參考平面具有第二夾角B2,此第二夾角B2大於或等於10度。在本實施例中,第二環形斜面S12直接地相鄰於第一環形斜面S11,但本新型創作並不限於此。如此一來,傳遞至環形凹槽G內的感測光束L2可藉由第二環形斜面S12而朝遠離入光口P的方向傳遞,進而避免讓雜散光L3藉由中框100的結構表面而反射進入指紋感測模組50,從而避免指紋感測模組50感測出雜訊光訊號。In this embodiment, the first surface S1 of the
綜上所述,在本新型創作的電子裝置中,藉由環形凹槽設計,使得中框可減少反射雜散光至指紋感測模組,從而避免指紋感測模組感測出雜訊光訊號而有效提升指紋感測效果。To sum up, in the electronic device created by the present invention, the ring-shaped groove design enables the middle frame to reduce the reflection of stray light to the fingerprint sensor module, thereby preventing the fingerprint sensor module from sensing noisy light signals And effectively improve the fingerprint sensing effect.
