    摘要: A light source includes a first light emitting source (2), a second light emitting source (3), a color-adjusting apparatus (1) with light wavelength conversion material, a control unit, and a positioning apparatus provided on the color-adjusting apparatus (1). The positioning apparatus sends a positioning signal which indicates a position of the color-adjusting apparatus to the control unit. The control unit outputs a control signal to the power switch of the second light emitting source so that the second light emitting source is controlled to stop emitting the light when the light generated by the color-adjusting apparatus is the same as that of the first light emitting source. A control method for light source and a projection system having light source are also disclosed.

    摘要: A light source system and a projection system applied thereby. The light source system includes a light source (10) emitting excitation light, a moving device (20) provided with an optical wavelength conversion material and an adjustment device (30). The excitation light irradiates on the optical wavelength conversion material. When the moving device (20) is in a periodical moving state, the light spot position irradiated by the excitation light on the moving device (20) moves following a first working track. The adjustment device (30) is used for adjusting the light spot position so that the light spot position irradiated by the adjusted excitation light on the moving device (20) moves following a second working track. The first working track is separated from the second working track. The present invention can reduce the working load of the optical wavelength conversion material on the first working track, thus slowing the aging speed of the optical wavelength conversion material, and improving the service light of the light source system.

    摘要: A display device may include a first substrate, a second substrate, and a liquid crystal layer. The first substrate may include a domain-forming layer including a depression pattern for forming a liquid crystal domain in a pixel area and a pixel electrode formed on the domain-forming layer. The second substrate may face the first substrate. The second substrate may include a common electrode formed on the entire surface thereof. The liquid crystal layer may be disposed between the first substrate and the second substrate. The liquid crystal layer may include a reactive mesogen (RM) which fixes liquid crystal molecules formed in the liquid crystal domain. Since a liquid crystal domain may be formed without a separate pattern on a common electrode, a display device having an enhanced aperture ratio and an enhanced viewing angle may be manufactured.

    摘要: A two level cross-correlation based system for watermarking continuous digital media at the system application level. It is a post-compression process for watermarking where no a priori knowledge of the underlying compression algorithm is required. Per each compressed media frame, a current unique digital signature is generated based on the data from the current compressed frame plus the digital signature that has been previously generated. The signature thus generated is then used in conjunction with the next compressed frame to generate the next unique digital signature. All digital signatures are correlated according to the above process until a “reset” signal is issued. A new chain of correlated digital signatures is produced by the system with a predetermined initial signature.
