Embodiment Construction

[0026] As mentioned in the background art, the popularity of large screens and full screens makes many electronic devices cancel active buttons, and the method of collecting fingerprints through active buttons is limited in use. The fingerprint recognition function is integrated on the screen, which can meet the requirements of fingerprint recognition and full-screen display effect of handheld terminals such as smart phones and tablet computers at the same time. Since the working principle of capacitive fingerprint recognition is similar to that of touch panels, it provides technical feasibility for the integration of fingerprint recognition with touch functions; however, when using the existing touch display structure to integrate fingerprint recognition, moiré The interference problem is relatively prominent, so that the fingerprint identification effect of the existing display structure is poor. The inventor found through research that the reason for the moiré interference ...

Abstract

The invention discloses a display structure, a display screen and electronic equipment, and the display structure comprises a substrate; a pixel layer which is arranged above the substrate and comprises a plurality of sub-pixels arranged in an array; a sensing layer, wherein the projection of the sensing layer and the projection of the pixel layer on the substrate at least partially coincide; thedensity of the sub-pixels is different from the density of the electrodes of the sensing layer. According to the invention, different densities are set for sub-pixels of a pixel layer and a motor of asensing layer in a display structure; moire pattern interference occurring when capacitive fingerprint identification is carried out through the sensing layer is effectively reduced. Therefore, the fingerprint recognition effect of the display panel is improved, a smart phone, a tablet personal computer and other handheld terminals do not need to collect fingerprints through movable keys any more, the problem that fingerprints cannot be collected through movable keys due to the fact that the movable keys are cancelled by electronic equipment is solved, and the requirements of a large screen and a full screen for the display effect can be met.

Description

technical field [0001] The invention relates to the technical field of display devices, in particular to a display structure, a display screen and electronic equipment. Background technique [0002] Existing electronic devices, such as handheld terminals such as smart phones and tablet computers, are generally equipped with a fingerprint recognition function. When collecting fingerprints, it is generally collected through the movable buttons at the bottom of the screen. The popularity of large screens and full screens has made many electronic devices cancel the movable buttons. Therefore, the method of collecting fingerprints through movable buttons has been restricted in use. Contents of the invention [0003] In view of this, the embodiments of the present invention provide a display structure, a display screen and an electronic device to solve the problem that fingerprints cannot be collected through the active keys due to the cancellation of the active keys on the elec...
