A method for adjusting the signal frequency includes: acquiring a first number of times of outputting a reference signal at an active level within a reference duration, wherein a correlation between a frequency of the reference signal and temperature is less than a reference correlation threshold, the reference duration is negatively correlated with a frequency of a clock signal, a correlation between a frequency of a clock signal and temperature is greater than the reference correlation threshold, and a drive signal for driving a display device to display an image is generated based on the clock signal; acquiring a target adjustment value based on the first number of times if the first number of times is different from a reference number of times; and controlling and adjusting the frequency of the output clock signal based on the target adjustment value.

Method and apparatus for adjusting signal frequency, display device and storage medium

A data transmission method comprises: receiving and storing image data, wherein the image data comprises first data and second data, the first data is encrypted verification data, and the second data is original data; comparing the first data with the second data in stored image data; replacing the second data with the first data, if the second data and the first data are inconsistent.

Data transmission method and device, display device

The present application relates to a fingerprint identification module and a display device. The fingerprint identification module includes: a first lens assembly; a second lens assembly with a primary optical axis not parallel to a primary optical axis of the first lens assembly; a reflecting mirror assembly, including a reflecting mirror and a rotating shaft coupled to the reflecting mirror, wherein the rotating shaft can drive the reflecting mirror to rotate, and the reflecting mirror includes a reflecting surface; and a light-sensitive element located at a light exiting side of the second lens assembly. The first lens assembly converges fingerprint-reflected light and projects the fingerprint-reflected light onto the reflecting surface, the reflecting surface reflects the fingerprint-reflected light to the second lens assembly, the second lens assembly converges the fingerprint-reflected light to the light-sensitive element, the light-sensitive element converts the fingerprint-reflected light into an electrical signal to identify fingerprint information.

Fingerprint identification module and display device

Disclosed are a print recognition module and a display device. The print recognition module includes a light guide structure including a light guide plate and an optical path adjusting component. The light guide plate includes a light incident surface and a light emergent surface arranged oppositely, and side surfaces connected between the light incident surface and the light emergent surface. A first optical sensor at a side of the light emergent surface, and a second optical sensor arranged corresponding to at least one of the side surfaces are provided. The optical path adjusting component is disposed between the side face and the second optical sensor, and includes a reflector. An included angle between the reflector and the light incident surface is an acute angle, and the reflector reflects at least part of light incident from the light incident side to the second optical sensor.
