  • Patent number: 9274373
    Abstract: A metal structure that holds a display unit, as the main structure, and a casing structure that is integrally molded from resin onto the metal structure. The metal structure is resilient against flexural loads, torsional loads, and other deformations from the exterior upon the display unit composed of thin plate glass, because the member that protects the display unit is in a box shape. The display unit itself can be protected from damage even if rigidity is reduced because of a thinner profile. The metal structure is manufactured by thin plate pressing and sufficient strength can be maintained even if the thickness is low. Furthermore, the metal structure is configured as a frame part of the entire casing, the rigidity of the entire device can therefore be maintained by using this structure, and the mounting board and functional components other than the display unit can also be protected.

  • Patent number: 9224622
    Abstract: In order to shield the light incident from the chip side surface or chip rear surface of a semiconductor chip that forms an LCD driver, a light-shielding film is formed over the chip side surface and chip rear surface of the semiconductor chip itself, not using a light-shielding tape that is a component separate from the semiconductor chip. Accordingly, the light-shielding tape as a separate component is not used, and hence the trouble that the light-shielding tape may protrude from the surface of a glass substrate whose thickness has been made small can be solved. As a result, the thinning of a liquid crystal display, and the subsequent thinning of the mobile phone in which the liquid crystal display is mounted can be promoted.
