摘要： An embodiment relates to an optical polyester film. The optical polyester film according to one embodiment can minimize the difference between the orientation angle at the center and the orientation angle at the end of the film while producing a difference between the tensile strengths in the lengthwise/widthwise directions of the film, thereby increasing mechanical strength and brightness and suppressing the occurrence of polarization Mura defects. Further, the optical polyester film employs a single layer film, and thus is more easily processed and has a slimmer thickness. Therefore, the optical polyester film can be usefully applied to small-sized thin film display devices and, specifically, can be favorably used as a substrate material of a prism sheet or a polarized reflection sheet.

摘要： The polyester film according to the embodiment achieves the elasticity required for a cover of a flexible display by increasing the rate of increase in stress in an initial stage of strain to a certain level or higher. As a result, it is possible to maintain the original characteristics when it is applied to a cover of a flexible display device and subjected to a plurality of repeated folding. Accordingly, the polyester film can be applied to a cover of a flexible display device, in particular, a foldable display device to exhibit excellent characteristics.

摘要： A wireless charging apparatus according to an embodiment may improve both the charging efficiency and the heat dissipation characteristics by use of a three-dimensional structure in a magnetic portion. In detail, the wireless charging efficiency may be increased and heat generated from the magnetic portion may be lowered by increasing the thickness of the magnetic portion near a coil portion, where electromagnetic energy is concentrated during wireless charging, and by reducing the thickness of the magnetic portion in the center, where the density of the electromagnetic energy is relatively low. Accordingly, the wireless charging apparatus can be efficiently used in a mobile means such as an electric vehicle that requires transmission of a large amount of power between a transmitter and a receiver.

摘要： A light reflective resin film includes a reflective stack including a resin layer, and the resin layer has a melting resistance of 2000 MΩ or less. The melting resistance is measured by bringing a copper plate into contact with a resin layer in a molten film state and applying a voltage of 50 V to the copper plate. By improving the energization performance of the resin layer, it is possible to reduce or eliminate the optical pattern in the light reflective resin film.
