The present disclosure provides an optical imaging module, an optical imaging device and an electronic device. The optical imaging module includes a first lens group and a second lens group arranged in sequence from an object side to an imaging surface. The first lens group has a positive refractive power, and includes a first lens having a positive refractive power and a second lens having a negative refractive power arranged in sequence from the object side to the imaging surface. The first lens includes a convex object-side surface and a convex image-side surface. The second lens group includes a plurality of lenses with refractive power, and the plurality of lenses with refractive power include at least one movable lens configured to focus on objects to be photographed at different distances by moving along the optical axis.

Optical imaging module and device and electronic device

A photographing lens system, a photographing device and an electronic apparatus are provided. The photographing lens system includes a first lens group and a second lens group in sequence from an object side to an image side. The first lens group includes N lenses, and N is an integer greater than 2. In a direction from the object side to the image side, lens one in the first lens group is a first lens, and lens N in the first lens group is a second lens. The first lens is a lens with a positive focal power, and the second lens is a lens with a focal power. The second lens group includes at least one lens with a focal power. An air gap between the first lens group and the second lens group is changed in the process of focusing between an infinite distance and a closer distance.

Photographing lens system, photographing device and electronic apparatus

A telephoto imaging system includes: a solid lens assembly and a tunable lens assembly. The solid lens assembly includes a first group, a second group, and a third group of solid lenses along the optical axis from the object plane to the image plane. The tunable lens assembly is configured for zooming under the effect of a driving mechanism to achieve focusing on objects at different distances. The following condition is satisfied by the tunable lens assembly when at least an in-focus state exists in the focusing process: 0<|delta(f/ft)|<0.9.

Telephoto imaging system, lens, and camera module

A display module includes: an image capturing area, and a plurality of pixel units disposed in the image capturing area, wherein each of the pixel units comprises one anode unit which includes at least three anodes; wherein anode units of the pixel units are periodically arranged with one anode group as a basic unit to form a plurality of anode groups, each of the anode groups comprises at least two of the anode units, and arrangements of anodes of at least two of the anode units in each of the anode groups are different.

Arrangement of anodes in display module, display panel and electronic device

A display panel includes a substrate and at least one pixel having a plurality of sub-pixels with a light transmission gap between two adjacent sub-pixels; the sub-pixel includes a metal circuit layer disposed on the substrate, a first electrode layer as a non-transparent anode disposed on the metal circuit layer, a light emission layer disposed on the first electrode layer, and a second electrode layer disposed on the light emission layer. Interference with effective imaging is reduced by adding the light shield layer in each display unit of the display panel to reduce stray light entering the imaging component, optimizing lossless rendering of the imaging quality of the under-screen imaging component, thereby balancing resolution and imaging quality.

Display panel, display screen, and electronic device

Disclosed in embodiments of the present application are a QR code generation method and apparatus for a terminal device. The terminal device comprises a camera. A specific implementation mode of the method comprises: receiving a QR code generation instruction input by a user, wherein the QR code generation instruction comprises a QR code information; starting a camera, and generating a camera real-time photographing picture; and generating a real-time picture displaying the QR code based on the QR code information and the generated camera real-time photographing picture. The implementation mode enables the user to clearly distinguish whether the QR code is an originally generated QR code, thereby improving the security of the QR code.
