A display module including a folding area, a first non-folding area, a second non-folding area and a digitizer that is disposed under the display module and that includes a sensing part including sensing coils and a shielding part disposed under the sensing part. The shielding part includes an adhesive layer including an opening overlapping the folding area, a first shielding layer disposed inside the adhesive layer and that includes a first folding portion overlapping the folding area and a first non-folding portion overlapping the first non-folding area, a second shielding layer disposed inside the adhesive layer and including a second folding portion overlapping the folding area and a second non-folding portion overlapping the second non-folding area, and a protective layer disposed under the adhesive layer, the first folding portion and the second folding portion overlap each other and are exposed by the opening.

Electronic device having a digitizer with improved shielding performance

Provided is a method of controlling a battery pack, and a battery pack controlled by the method. A battery pack includes a plurality of slave battery modules, each of the slave battery modules including a battery that includes at least one battery cell and a slave controller that is configured to control charge and discharge of the battery, a master battery module including a master controller that is configured to control the slave controller, and a communication cable having formed thereon a first port to which the master controller is connected and a plurality of second ports to which the slave controller is connected. The first port includes an identification terminal configured to output an identification signal which is an electrical signal corresponding to the number of the second ports. A method of controlling the battery pack is provided.

Battery pack and method for controlling battery pack

A battery module system includes a master module and at least one slave module that are connected in series. An isolated communication is performed between the master module and the at least one slave module.

Battery module system

There is provided a power conversion apparatus including first to fifth nodes. The power conversion apparatus includes: an inverter including a first switch between the first and second nodes, a second switch between the first and third nodes, a third switch between the second and fourth nodes, and a fourth switch between the third and fourth nodes; a filter including an inductor connected between the second and fifth nodes and a capacitor connected between the fifth and third nodes; and a current sensor configured to sense resultant current, which is the sum of inductor current flowing in the inductor and output current, wherein the output current is output to a load connected between the third and fifth nodes.

Power conversion apparatus and uninterruptible power supply comprising same

A slave module receives a first wake-up signal from an adjacent previous module to perform a wake-up operation and to transmit a second wake-up signal to an adjacent subsequent module. The slave module includes: an analog front end (AFE) including a first terminal and a second terminal, the AFE may be woken up by receiving the first wake-up signal through the first terminal and may output a first voltage through the second terminal in a woken up state; a processor including a third terminal electrically connected to the first terminal, a fourth terminal electrically connected to the second terminal, and a fifth terminal electrically connected to a second slave terminal. The processor may boot up when the first voltage is applied to the fourth terminal, may output a second voltage to the third terminal after being booted up, and may output the second wake-up signal to the fifth terminal.

Slave module

A display includes: a first support member (FSM); a second support member (SSM); joint units (JUs) arranged in a first direction (FD), extending in a second direction (SD), and between the FSM and the SSM; and a flexible display module on the FSM, the SSM, and the JUs. Each JU includes: a body part (BP) extending in the SD; and protruding parts (PP) on opposing sides of the BP, each PP having a fan shape (FS) and being on an upper end of the BP. Each PP includes: an arced curved surface (CS), and a first inclined surface (FIS) and a second inclined surface (SIS) defined as radii of the FS. An angle between the FIS and a third direction (TD) is equivalent to an angle formed between the SIS and the TD. The CSs of some PP on a same upper end of the BP face each other.
