A liquid crystal display device having fingerprint identification device for enhancing aperture ratio and transmissivity of a TFT-LCD panel is disclosed. A fingerprint identification substrate (400) is attached to a TFT substrate (300). The TFT substrate has color-filter-on-array structure in which the color filters (336) and the thin film transistors can be eliminated, the aperture ratio is increased, and the quality of image display is enhanced. In addition, the transmissivity is increased according to the decrease of the number of glass substrate used in the liquid crystal display device, so that the sensitivity of fingerprint identification is enhanced.

A photoelectric composite connector, comprising a socket body provided with a socket sealing chamber and a plug body provided with a plug sealing chamber, the socket sealing chamber is composed of an inner wall of a movable sleeve, an outer wall of a first optical fiber module support member in the socket, and a first optical fiber module support member in the socket. Surrounded by insulators, the movable sleeve bends the optical pins obliquely protruding from the first optical fiber module support to be arranged axially along the socket body, and a movable column and an obliquely arranged jack are arranged in the plug sealing cavity. During the process, the first optical fiber module support pushes the movable column into the plug sealing chamber, the movable sleeve slides into the socket body relative to the first optical fiber module support, the elastic tube restores the tilting device, and the optical pin is arranged in the elastic tube, thereby realizing The optical pin is inserted into the optical jack. The invention has good sealing performance, can realize the underwater plugging and unplugging of the connector, prevents external liquid from entering into the chamber of the connector during the underwater plugging and unplugging process, and ensures the cleanliness of the optical contacts during the underwater plugging and unplugging process.

The invention discloses a battery and belongs to the field of electronic devices. The battery comprises an electric core module used for storing electric energy, a protection module used for protecting the electric core module, a communication module used for exchanging information with the external environment and a real-time clock module, wherein the protection module is electrically connected with the electric core module and the real-time clock module is electrically connected with the communication module. Due to the fact that the real-time clock module is arranged in the battery, the purposes that a button cell in a mobile terminal is omitted and the design margin of the mobile terminal is larger are achieved.
