Flexible display apparatus and method of controlling flexibility of the same
A flexible display apparatus includes a flexible substrate; a display layer on the flexible substrate and including a plurality of pixels; a cover layer which covers the display layer; a heating electrode layer on a surface of the flexible substrate opposite to the display layer, between the flexible substrate and the display layer, between the display layer and the cover layer, or on a surface of the cover layer opposite to the display layer; and a temperature sensing unit configured to sense an external temperature to the flexible display apparatus.
Method For Producing An Electronic Component, And Electronic Assembly, A Heating Device Being Provided In The Substrate Of The Assembly
A method for producing or disassembling an electronic assembly are provided. The assembly may have a heating device integrated into a substrate. The heating device can be heated via an external power supply during the assembly process so that, for example, solder connections of an electric component can be melted. The heating device can also be used when operating the electronic assembly, and the heating device can then be directly actuated by the component. For this purpose, an electric connection is then established between the component and the heating device, the connection not yet being provided during the thermal assembly process in order to protect the electronic components of the circuit from being damaged.
THREE-DIMENSIONAL PRINTING CONDUCTIVE ELEMENTS
Methods and systems for making three-dimensional printed articles. In one example, a method of making a three-dimensional article can include printing a conductive element including a composite of a conductive material and a polymeric build material; printing an adjacent portion in contact with the conductive element, where the adjacent portion includes a nonconductive polymeric build material; and heating the conductive element by running an electric current through the conductive element, and thereby heating the adjacent portion to a temperature sufficient to change a physical property of the nonconductive polymeric build material of the adjacent portion.
Electronic component assembly apparatus
An electronic component includes a wiring substrate having a first surface and a second surface, an electronic component body mounted on a first surface side of the wiring substrate, an external electrode formed on a second surface side of the wiring substrate which is opposite to the first surface side, the external electrode being electrically connected to the electronic component body, a heat generating member having a conductive property and having a higher resistivity than the external electrode, and a heat insulating layer disposed between the electronic component body and the heat generating member, the heat insulating layer having an insulating property and being formed of a material different from an other material of the wiring substrate.
