摘要： A lens (3), glasses, and a lens (3) adjustment method are provided. The lens (3) includes a first lens layer (3a). The first lens layer (3a) includes a plurality of liquid crystal regions (3021). At least one liquid crystal region (3021) forms a first optical region. At least one liquid crystal region (3021) forms a second optical region. Optical powers of the liquid crystal regions (3021) may be changed by controlling rotation of liquid crystal molecules in the liquid crystal regions (3021) separately included in the first optical region and the second optical region, so that an optical power of the first optical region can be different from an optical power of the second optical region. In this way, the optical power produced by the first optical region may correspond to a myopia degree of a user, and the optical power of the second optical region may correspond to a defocus degree. Therefore, when a gaze point of a human eye falls within the first optical region, clear distant vision can be obtained. The second optical region may provide defocus effect, to achieve effective myopia prevention and control effect for the human eye.

摘要： A reflector (10), a method for manufacturing the same, a lens module (001), and an electronic device are provided, and pertain to the field of optical technologies. The reflector (10) uses a silicon-based substrate (101) with a planar structure as abase material, which can effectively reduce a volume and mass of the reflector (10) when compared with a right triangular prism. In addition, an included angle (γ) between a second side surface (1d) and a second surface (1b) of the silicon-based substrate (101) is designed as an obtuse angle, to ensure that after the reflector (10) is arranged in an inclined manner, a right angle protruding outward is not formed between the second side face (1d) and the second surface (1b). Therefore, space occupied when the reflector (10) applied to a periscope camera module can be reduced, but also a risk of cracking or edge breakage of a side edge of the silicon-based substrate (101) caused due to collision or friction during assembly of the reflector (10) can be reduced.

摘要： A method provided by the present invention for transmitting overhead information, includes dividing and reforming to-be-transmitted overhead information into at least two overhead parts; inserting the at least two divided overhead parts into overhead bytes of at least two corresponding data frames successively, wherein the at least two divided overhead parts corresponds to the overhead bytes and transmitting via the at least two data frames. Overhead information transmitting apparatus and overhead information receiving apparatus are also provided by the present invention. With the method and apparatus of the present invention, the channel bandwidth resources occupied by the overhead bytes of each microwave frame are greatly reduced. If the saved channel bandwidth is used for performing the error correction code on the transmitted information, the code gain is improved and the sensitivity requirement on the receiver is reduced so that the cost of a microwave transmitting system is reduced eventually.
