Problems solved by technology

[0005] With the development trend of ultra-thin electronic products, the size of existing optical fingerprint and palmprint collection devices is difficult to meet the ultra-thin size requirements of existing electronic products
On the one hand, the ultra-thin fingerprint and palmprint collection devices for semiconductor chips are extremely expensive, and on the other hand, they have low aesthetics, which cannot well meet the needs of ultra-thin electronic products.
At the same time, the thickness of the optical collector is too thick, which is difficult to meet the needs of ultra-thin ultra-thin electronic products

Embodiment 1

[0105] Such as figure 1 As shown, the ultra-thin fingerprint and palmprint collection device of this embodiment at least includes a light guide plate, an imaging light source and a collector, wherein

[0106] The imaging light source 102 is used to provide light, and the imaging light source is arranged at the end of one side of the light guide plate corresponding to the collection area;

[0107] As for the light guide plate 2 , part or all of the upper surface of the light guide plate is a collection area. In this embodiment and the following embodiments, the area of ​​the collection area on the light guide plate is not limited and can be set as required. The collection area is used to bear fingerprints. The light emitted by the imaging light source is incident into the light guide plate from the end surface of the light guide plate, the light passes at least through the collection area, and the light is transmitted through total reflection in the light guide plate. This em...

Embodiment 2

[0128] Such as Figures 2 to 5 As shown, the ultra-thin fingerprint and palmprint collection device of this embodiment at least includes

[0129] an imaging light source 102, configured to provide light;

[0130] As for the light guide plate 2 , part or all of the upper surface of the light guide plate is a collection area. In this embodiment and the following embodiments, the area of ​​the collection area on the light guide plate is not limited and can be set as required. The collection area is used to bear fingerprints. The light emitted by the imaging light source is incident into the light guide plate from the end surface of the light guide plate, the light passes at least through the collection area, and the light is transmitted through total reflection in the light guide plate. The collector receives the emitted light of the fingerprint, and forms fingerprint image data based on the received reflected light.

[0131] The collector in this embodiment also includes a sm...

Embodiment 3

[0143] Such as Figure 7 As shown, the electronic device described in this embodiment uses the collector 5 on the edge of the terminal device 6, such as a mobile phone, which may be on the HOME key. Compared with common camera components, this collector has the characteristics of simple structure and thinner thickness. The fingerprint and palmprint collection devices described in the extended embodiments of the above-mentioned embodiment 1 or embodiment 2 can also be used in the same way.

Abstract

The invention discloses an ultra-thin fingerprint and palm print collection device, display equipment capable of collecting fingerprint and palm print, and a fingerprint and palm print collection method, and mainly aims to provide the ultra-thin fingerprint and palm print collection device. The ultra-thin fingerprint and palm print collection device at least comprises a light guide plate, an imaging light source and a collector or a camera shooting assembly, wherein part or all of the upper surface of the light guide plate is a collection area used for bearing a fingerprint; the imaging light source is arranged on the end part of one side of the light guide plate of the corresponding collection area; the collector or the camera shooting assembly is arranged below the light guide plate of the corresponding collection area; and the collector or the camera shooting assembly and the light guide plate are spaced.

Description

technical field [0001] The invention relates to the technical field of collectors, in particular to an ultra-thin fingerprint and palmprint collection device, a display device capable of collecting fingerprints and palmprints, and a fingerprint and palmprint image collection method. Background technique [0002] There are roughly two types of existing fingerprint collection devices. One is based on the semiconductor chip to collect fingerprints by sensing the fingerprint texture of the finger. The other is an optical fingerprint collection device, which uses the optical difference caused by the ridges and valleys of the light on the interface when the finger touches to form a fingerprint image for collection. However, the semiconductor chip fingerprint collection method has insufficient antistatic and anti-corrosion capabilities, and the fingerprint collection sensitivity is not too high. Such as figure 1 Shown, existing optical fingerprint, palmprint collection device ar...
