Problems solved by technology

[0003] At present, one of the more popular fingerprint recognition technologies is hidden fingerprint recognition technology, which is to attach a fingerprint recognition module 2 to a part of the area under the transparent cover 1 of the display panel, such as figure 1 As shown, this kind of display panel generally uses software design to prompt the user for the fingerprint recognition area at the corresponding position in the visible area when the screen is on, so as to facilitate the user's use, but in this way, the position of the fingerprint recognition area cannot be identified when the screen is off. , thus affecting the user experience

Embodiment 1

[0033] see figure 2 A fingerprint recognition display panel provided in Embodiment 1 of the present invention includes: a base substrate 11, a transparent cover 12, a fingerprint recognition module 13 arranged between the base substrate 11 and the transparent cover 12, and a The optical film 14 between the fingerprint identification module 13 and the transparent cover 12 is opposite to the fingerprint identification module 13 , and the optical film 14 develops color when the viewing angle is greater than a predetermined critical angle.

[0034] Wherein, the transparent cover 12 may be a flexible cover, such as ultra-thin glass.

[0035] The fingerprint identification module 13 may include, for example, a fingerprint identification sensor. The fingerprint identification sensor may be of a pressing type or a swiping type. The embodiment of the present invention does not limit the type of the fingerprint identification module. Usually, the fingerprint recognition module 13 is d...

Embodiment 2

[0047] The fingerprint recognition display panel provided by Embodiment 2 of the present invention is similar to the fingerprint recognition display panel provided by Embodiment 1 of the present invention, and the same parts will not be repeated here, and the different parts will be described below.

[0048] see Figure 10 The fingerprint identification display panel provided by Embodiment 2 of the present invention further includes: a protective layer 15 disposed on the side of the transparent cover plate 12 facing away from the fingerprint identification module 13; an optical film 14 is disposed between the fingerprint identification module 13 and the protective layer 15 . Generally, the protective layer 15 is disposed on the outermost side of the fingerprint identification display panel.

[0049] For example: the optical film 14 is arranged between the transparent cover plate 12 and the protective layer 15, such as Figure 10 shown; of course, the optical film 14 can also...

Embodiment 3

[0052] The fingerprint recognition display panel provided by Embodiment 3 of the present invention is similar to the fingerprint recognition display panel provided by Embodiment 2 of the present invention, and the same parts will not be repeated here, and the different parts will be described below.

[0053] see Figure 11 , the fingerprint identification display panel provided by Embodiment 3 of the present invention also includes: a semiconductor film 16 arranged between the transparent cover plate 12 and the protective layer 15; semiconductor stripes spaced from each other are formed on the semiconductor film 16; the optical film 14 is arranged on the transparent between the cover plate 12 and the semiconductor film 16 .

[0054] The semiconductor thin film 16 can be prepared, for example, by a vacuum deposition method, and the material of the semiconductor thin film 16 is a semiconductor polymer, indium tin oxide, zinc tin oxide, and the like.

[0055] The semiconductor s...

Abstract

The invention provides a fingerprint identification display panel and a fingerprint identification display device and aims to identify the position of a fingerprint identification area under a light condition and improve the user experience. The fingerprint identification display panel comprises a substrate, a transparent cover plate and a fingerprint identification module which is arranged between the substrate and the transparent cover plate, an optical film opposite to the fingerprint identification module is arranged on the side, away from the substrate, of the fingerprint identification module, and the optical film displays color when a viewing angle is larger than a preset critical angle.

Description

technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to a fingerprint identification display panel and a fingerprint identification display device. Background technique [0002] Fingerprint is an invariable feature that is unique and distinguishable from others. It consists of a series of ridges and valleys on the skin surface of the fingertips. The details of these ridges and valleys usually include the bifurcation of ridges, the Details such as ends, arches, tent-like arches, left-handed, right-handed, spiral or double-handed, determine the uniqueness of the fingerprint pattern. With the rapid development of display technology, display panels with a fingerprint recognition function have gradually spread in people's lives. [0003] At present, one of the more popular fingerprint recognition technologies is hidden fingerprint recognition technology, which is to attach a fingerprint recognition module 2 to a part of...
