    摘要: A display module includes a display panel and a dimming panel stacked on the display panel. The display panel has a plurality of pixel regions. The dimming panel has a plurality of dimming regions, and in a direction perpendicular to the display panel, a dimming region covers at least one pixel region. The dimming panel includes a plurality of dimming electrodes and a plurality of signal lines. Each dimming electrode is located in a dimming region in the plurality of dimming regions, and any two adjacent dimming electrodes have a gap therebetween. Each dimming electrode directly electrically connected to at least one signal line. The at least one signal line is configured to transmit a control voltage signal to the dimming electrode electrically connected to the at least one signal line for controlling a transmittance of the dimming region where the dimming electrode is located.

    摘要: A device for detecting a missing element on a circuit board comprising a positioning tray, a data processing assembly, a lifting control assembly, and a detecting assembly. The positioning tray supports and positions a circuit board to be tested. The data processing assembly is connected with the lifting control assembly and the detecting assembly, and sends a control signal to the lifting control assembly, receives detection data sent by the detecting assembly, and compares the detection data with preset reference data to obtain a detection result of a missing element. The detecting assembly moves up and down between an initial position and a preset position under the control of the lifting control assembly, and sends the detection data to the data processing assembly according to a contact state with elements on the circuit board to be tested at the preset position.
