Abstract

The present invention relates to a display-lighting fingerprint recognition method, especially characterized in that the display directly provides the light source required for fingerprint recognition. The method comprises the steps of providing a touch panel, a display, and more than one fingerprint recognition receiver; and triggering the display to provide a sequential light source required for fingerprint recognition when a finger touches the touch panel and transmitting reflected lights of the sequential light source when it touches the finger to the fingerprint recognition receiver for fingerprint recognition. Because the display directly provides the light source required for wide-angle and high-density fingerprint recognition, there is no need to set up a special light source assembly for fingerprint recognition so as to achieve the thinning design of the entire component. The entire touch panel can be used as the recognition area for fingerprint recognition. It can also provide full-screen multi-point fingerprint recognition based on the multi-touch feature of the touch panel. Moreover, multiple fingerprint recognition can be achieved by more than one fingerprint recognition receiver to obtain better fingerprint recognition accuracy. When the minimum resolution of a general 5-inch display is 1280x720, there are about 293 ppi per inch, that is, each inch can provide 293 light sources required for fingerprint recognition. When a finger touches the touch panel, it will touch the display to generate a sequential light source with a wide angle required for fingerprint recognition. When the sequential light source touches the finger, the reflected light will be transmitted to more than one fingerprint recognition receiver for fingerprint recognition. In addition, each light-emitting point of the display can provide a wide-angle light source. The higher the number of light source points used in fingerprint recognition, the more detailed and accurate fingerprint information can be obtained. The multi-touch feature of the touch panel can achieve multiple-point fingerprint recognition.

Description

一種顯示器給光式指紋辨識方法 Method for identifying light-emitting fingerprints of display

本發明的目的係為一種顯示器給光式指紋辨識方法，尤指一種應用於由顯示器直接提供指紋辨識時所需之光源，因是由顯示器直接提供寬角度且高密度之指紋辨識時所需之光源，故不需另設指紋辨識專用光源組件；整個觸控面板皆可做為指紋辨識時之辨識區也能依觸控面板的多點觸控特長，而能提供全螢幕多點式指紋辨識；並且能由一個以上之指紋辨識接收器來達成多重指紋辨識，以達更佳的指紋辨識精準性。 The purpose of the present invention is a display-light fingerprint recognition method, especially a light source used when the display directly provides fingerprint recognition, because the display directly provides wide-angle and high-density fingerprint recognition.

It can also provide full-screen multi-point fingerprint recognition based on the multi-touch features of the touch panel ; And can achieve multiple fingerprint recognition by more than one fingerprint recognition receiver to achieve better fingerprint recognition accuracy.

在一般5吋顯示器的最低解析度為1280x720時，其每英吋約為293ppi即每英吋能提供293個的指紋辨識時所需的光源，並且顯示器每個發光點是能提供一具有寬角度的光源，而指紋辨識時所用的光源點數越高，能得到的指紋資訊就越詳細、精準；且觸控面板的多點觸動特長，也能達到多點式指紋辨識。 When the minimum resolution of a general 5-inch display is 1280x720, its per inch is about 293ppi, which means it can provide 293 light sources for fingerprint recognition per inch, and each luminous point of the display can provide a wide angle The higher the number of light sources used for fingerprint recognition, the more detailed and accurate fingerprint information can be obtained; and the multi-touch feature of the touch panel can also achieve multi-point fingerprint recognition.

為達成前揭目的，本發明係提供一種顯示器給光式指紋辨識方法，因是由顯示器直接提供寬角度且高密度之指紋辨識時所需之光源，故不需另設指紋辨識專用光源組件也就能達到整個組件輕薄化、整個觸控面板皆可做為指紋辨識時之辨識區也能依觸控面板的多點觸控特長，而能提供全螢幕多點式指紋辨識、也能依多重指紋辨識的需求而設立一個以上之指紋辨識接收器就更能精準辨識指紋。 In order to achieve the purpose of the foregoing disclosure, the present invention provides a display-to-light fingerprint recognition method. Because the display directly provides the light source required for wide-angle and high-density fingerprint recognition, there is no need to set up a special light source assembly for fingerprint recognition. It can achieve the light and thinness of the entire component, the entire touch panel can be used as the recognition area for fingerprint recognition, and it can also provide full-screen multi-point fingerprint recognition based on the multi-touch features of the touch panel, and can also provide multi-touch fingerprint recognition. For fingerprint recognition requirements, the establishment of more than one fingerprint recognition receiver can more accurately recognize fingerprints.
