A hand-held display device includes a container having a front display having a perimeter, a top side, a left side, a right side, and a bottom side, together all defining the perimeter of the front display, and a back side. The front display includes a plurality of display portions. Each display portion provides an array of display markers. The display markers are configured to display a first side when an electrical current is passed therethrough and a second side when the electrical current is not passed therethrough. A plurality of controllers is mounted on the container. The plurality of controllers equals the plurality of display portions. Each controller is configured to selectively pass the electrical current through a predetermined configuration of the display markers in a respective one of the first plurality of display portions, such that a predetermined indicia is displayed.

The present disclosure relates to the field of display technologies and provides a display panel and a display apparatus for improving the accuracy of test signals acquired in a VT test. The display panel includes a base substrate. The base substrate is provided with a plurality of test leads in a non-display area, and the plurality of test leads includes a circuit board lead and a test point lead. The base substrate is also provided with a test pad and a test circuit board pin in the non-display area. The circuit board lead is electrically connected to the test circuit board pin, the test point lead is electrically connected to the test pad, and the test pad being reused as a circuit board alignment mark.

A display device including a substrate having a display area and a non-display area outside the display area, a plurality of pixels disposed in the display area on the substrate, a plurality of data lines connected to the pixels, a first crack detection line disposed in the non-display area on the substrate, the first crack detection line being electrically connected to at least one of the data lines, and a second crack detection line disposed in the non-display area outside the first crack detection line, the second crack detection line being electrically connected to at least one of the data lines.

A plurality of luminous modules able to emit a segmented light beam to be controlled by a common control processor having a single video output interface, while maintaining the ability to project different outlines with each luminous module. This decreases the number of connections necessary between a control unit and a plurality of luminous modules, thereby decreasing the complexity of the system, and decreasing the production cost thereof.
