Embodiment 1

[0026] This embodiment provides a fingerprint identification structure, such as figure 1 and figure 2 As shown, it includes a plurality of identification units 1 arranged in an array; each identification unit 1 includes a transmitting module 11 and a sensing module 12, and the sensing module 12 is arranged to receive the emission emitted by the transmitting module 11 and reflected by the fingerprint 100. The position of the light that comes back; in each identification unit 1, the wavelength of the light that the sensing module 12 can sense is the same as the wavelength of the light emitted by the emission module 11; wherein, at least part of the emission module in the adjacent identification unit 1 11 The emitted light has different wavelengths.

[0027] The emitting module 11 and the sensing module 12 appear in pairs, and the sensing module 12 is used for sensing the light emitted by the corresponding emitting module 11 and reflected by the fingerprint 100 . The emitting ...

Embodiment 2

[0042] This embodiment provides a display panel including the fingerprint identification structure provided in Embodiment 1 of the present invention.

[0043] Specifically, in the display panel of this embodiment, the fingerprint identification structure provided by Embodiment 1 can be used as a relatively independent component, and it can be bonded together with the display substrate in the display panel by a method such as bonding, or it can be implemented The emission module 11 and / or the sensing module 12 in the fingerprint identification structure provided in Example 1 are integrated in the sub-pixel layer of the display panel.

[0044] Optionally, the display panel includes a first substrate 2, and an array of sub-pixels (including red sub-pixels R, Green sub-pixel G, blue sub-pixel B); the emission module 11 is arranged on the same layer as the sub-pixel and is arranged in the gap between adjacent sub-pixels, and / or, the sensing module 12 is arranged on the same layer a...

Abstract

The invention provides a fingerprint identification structure and a display panel, belongs to the fingerprint identification and display technical field, and can partially solve the problems that an existing fingerprint identification structure is easy to have crosstalk. The fingerprint identification structure comprises a plurality of identification units arranged in an array; each identificationunit comprises an emission module and a sensing module; the sensing module is arranged in a position capable of receiving lights emitted by the emission module and reflected by the fingerprint; in each identification unit, the sensing module can sense that the light wavelength is equal to that of the light emitted by the emission module; the wavelengths of lights emitted by the emission modules in at least partial the adjacent identification units are different.

Description

technical field [0001] The invention belongs to the technical field of fingerprint identification and display, and in particular relates to a fingerprint identification structure and a display panel. Background technique [0002] The existing fingerprint identification structure, such as an in-screen fingerprint identification panel, is provided with array-distributed emission modules and array-distributed sensing modules on the panel with a display function. One transmitting module corresponds to one sensing module. The light emitted by the transmitting module is irradiated to the fingerprint and then reflected to the corresponding sensing module. The valleys and ridges of the fingerprint are distinguished according to the intensity of the reflected light (the reflected light intensity represents the ridge in the fingerprint corresponding to the location of the transmitting module. , the weak reflected light represents the valley in the fingerprint corresponding to the pos...
