Embodiment Construction

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] The present invention is aimed at the prior art fingerprint recognition display panel. Due to the cutting method of the special-shaped area, the display area around the special-shaped area has uneven light emission, and the design of the fingerprint recognition module will lead to the technical problem of reducing the screen ratio. This embodiment can solve the technical problem. defect.

Abstract

The invention provides a display panel for under-screen fingerprint identification, and comprises: a substrate which comprises a display area and a non-display area; a thin film transistor layer prepared on the substrate and comprising a plurality of data lines and gate lines; a pixel unit prepared on the thin film transistor layer corresponding to the display area; and virtual pixels prepared onthe thin film transistor layer corresponding to the non-display area. The non-display area includes a fingerprint identification prompt area for transmitting fingerprint information to a fingerprint identification module. When a finger touches the fingerprint identification prompt area, light emitted from the fingerprint identification prompt area is reflected after passing through the fingerprint, and the reflected light enters the fingerprint identification module through a gap between the virtual pixels to realize fingerprint identification.

Description

technical field [0001] The present invention relates to the technical field of display screens, in particular to a display panel for under-screen fingerprint recognition. Background technique [0002] AMOLED (Active Array Organic Light Emitting Diode Display) display panels have gradually become a new generation of display technology due to their high contrast ratio, wide color gamut, low power consumption, and foldability. In the field of mobile phone display, in order to increase the screen ratio and increase the area of ​​the display area, a U-Cut special-shaped cutting method is used in the existing panel technology, such as figure 1 As shown, the display panel includes a display area 03 and a non-display area, and a U-shaped area 01 is cut out of the non-display area on the upper part of the display panel for placing an earphone, a front camera, and the like. However, this design will cause uneven light emission due to the capacitive and resistive loading (RC loading) ...
