The present technology relates to a display module which enables the display module capable of improving a design quality of a product to be applied to various types of products. The display module is provided with a flexible sheet-shaped display unit, a switch unit which switches a display pattern of the display unit, and a control unit which controls a display pattern of the display unit on the basis of a switch control signal from the switch unit. The display unit is electrically connected to the control unit, and the control unit is electrically connected to the switch unit by using a wiring cable. The present technology is applicable to, for example, a bag and the like a display pattern of which may be changed.

The present application discloses a manufacturing device for a display panel. The manufacturing device for the display panel includes a base; at least one transfer mechanism, fixedly disposed on the base; and at least one detecting mechanism, fixedly disposed, on the base; a control mechanism is disposed in the base, the control mechanism controls the transfer mechanism and the detecting mechanism, and a set height of the detecting mechanism is smaller than that of the transfer mechanism.

A display panel, a display device and a method for driving the display panel. The display panel includes: a rotation axis; at least one display area located at one side of the rotation axis; wherein the display area includes a plurality of display sub-areas; and a plurality of driving-control modules corresponding to the plurality of display sub-areas. The plurality of display sub-areas are sequentially arranged along a first direction; the first direction is directed from the rotation axis to the display area; when the display panel rotates around the rotation axis, areas passed by the plurality of display sub-areas form a plurality of imaging sub-areas. The plurality of driving-control modules are configured to control the plurality of display sub-areas to have different display parameters, respectively, thereby enabling imaging brightness of the plurality of imaging sub-areas to be within a preset brightness range.

A magnetic erasing device including a magnet that includes an S pole and an N pole extending along an axial direction of the magnet, and a rotation mechanism for rotating the magnet in a housing around an axis of the magnet, wherein lines of magnetic force generated around the axis of the magnet during rotation of the magnet are designed to be applied to magnetic particles in the microcapsules to erase a visible image on a magnetic panel when the axis of the magnet is spaced from a surface of the magnetic panel by a predetermined distance.

A plurality of individually controllable LED modules (LEDs) are provided for displaying defined patterns. At least a first and second cables are provided with three or more conductive wires insulated from one another comprising at least one reference voltage wire, a positive voltage wire and a data wire. Each of a plurality of strips is maintained between the cables along a defined longitudinal distribution and receives the reference voltage, the positive voltage and the data therefrom. Each of the strips comprises a subset of the individually controllable LEDs positioned therealong in a defined transverse distribution. The display controller module comprises a processor that sends lighting instructions for the LEDs over the data wire. The lighting instructions are set considering the defined longitudinal distribution of the plurality of strips and the defined transverse distribution along each of the plurality of strips to provide the defined patterns.

A method for updating a content of an electronic label and a device are provided. The method includes: obtaining first object information of a first target object, where a distance difference between the first target object and a first coordinate position where a first electronic label is located is within a preset distance range; sending the first object information of the first target object to the first electronic label, and controlling the first electronic label to display the first object information of the first target object.

Provided is a method of displaying price tag information applied to a price tag generating apparatus in a shelf system which includes a shelf and at least one display screen arranged on the shelf. The method includes: acquiring an image of a commodity placed on the shelf; determining price tag related information based on the image of the commodity, wherein the price tag related information comprises price tag information of the commodity; and sending the price tag related information to a target display screen, which is a display screen for displaying the price tag information in the at least one display screen, and the price tag related information being configured to allow the target display screen to display the price tag information.
