Abstract: Disclosed is a display module comprising a timing controller which comprises an identification unit and a determination unit, wherein the identification unit is configured to receive and identify a control signal sent by the display controller and output a first feedback signal to the display controller when the control signal is identified as a handshake signal, the first feedback signal being used for triggering the display controller to send a handshake parameter; and the determination unit is connected to the display controller, and is configured to receive the handshake parameter sent by the display controller, determine whether the handshake parameter matches a handshake parameter pre-stored in the determination unit, if so, determine that handshake is successful, and output a second feedback signal to the display controller, the second feedback signal being used for triggering the display controller to send a video signal, and if not, determine that handshake fails.

Abstract: The present disclosure provides a display module and a medical spliced display system. The display module includes: a display panel; a back plate including a bottom wall and a side frame connected to each other to define an accommodating space; and a frame including a retaining wall and a supporting platform and an insert on the retaining wall; at least a portion of the retaining wall surrounds the side frame; the supporting platform extends toward the inside of the accommodating space for supporting the display panel; the insert is on a side of the side frame facing the accommodating space, to embed the side frame between the retaining wall and the insert.

Abstract: A display device and a medical endoscopic apparatus are provided. The display device includes: a display panel; a cover plate at a light exit side of the display panel; a backlight module, at a side of the display panel away from the cover plate; a middle frame, including: a first part, configured to support the display panel; a second part, connected with the first part and extends from the first part to the side away from the cover plate; the second part is around the backlight module at side of the backlight module; the display device includes a first space between the first part and the cover plate, a first side of the first space is limited by the cover plate, a second side of the first space is limited by the first part, the first side is opposite to the second side of the first space.

Abstract: Disclosed is a sex identification specific DNA sequence and a sex identification method of Chinese mitten crab Eriocheir sinensis. The sex identification specific DNA sequence is showed as SEQ ID NO:1. The sex identification method includes following steps:S1, extracting genomic DNA of Chinese mitten crab Eriocheir sinensis; S2, PCR amplification using the genomic DNA as template; an upstream primer for PCR amplification is as shown in SEQ ID No: 2 and a downstream primer is as shown in SEQ ID No: 3; S3, examining amplified products by agarose electrophoresis, and those with specific amplified bands are females, otherwise they are males. The method has high identification accuracy, is simple and easy to operate, and is suitable for sex identification of Chinese mitten crab Eriocheir sinensis at embryonic and larval stages.
