  • Publication number: 20190302510
    Abstract: The present invention relates to the field of a protection device for a curved-surface screen, in particular to a protection device suitable for a curved-surface screen of electronic equipment. The present invention provides two methods for preparing the curved-surface glass, one of which is non-hot-bending treatment, and the other is non-uniform thickness treatment of the glass before the hot-bending treatment, so that the prepared curved-surface tempered glass film and the screen of the electronic equipment can be completely attached by vacuum adsorption, thereby solving the problem of fragile screens.

  • Publication number: 20160135314
    Abstract: A screen protection film with a curve frame includes a lens diaphragm and a frame diaphragm. The lens diaphragm has a first fixed zone; the frame diaphragm has a second fixed zone; the first fixed zone connects with the second fixed zone. The frame diaphragm has the same curve radian as a display screen to be protected. Both the lens diaphragm and the frame diaphragm are made of PET diaphragm material by forming in mold. The screen protection film realizes protection to a whole curve screen. Usually, a curved surface deforms in 3 directions and a stretched frame diaphragm can deform in 3 directions to completely fit in with the radian of the curve screen and cover the whole curve screen; the PET as the base material ensures a good light transmittance. Even in stretching, the light transmittance also reaches more than 85%, surpassing PVC and PP materials.

  • Patent number: 7869504
    Abstract: Techniques for providing a coefficient scaling operational unit to perform the coefficient scaling computation for various image compression schemes are disclosed. To minimize multiple units, each for one image encoding/decoding scheme (e.g., MPEG4 and WMV9), a single coefficient scaling operational unit is designed to accommodate various standards. In one embodiment, the coefficient scaling operational unit comprises an arithmetic logic unit. The arithmetic logic unit operates in accordance with a formula involving multiplication and division. Parameters such as coefficients and quantization parameters are provided to perform the coefficient scaling operation.
