The present invention provides a smart TV application management method and a smart TV, wherein the smart TV application management method includes: when receiving an instruction to start any TV application, judging whether any TV application is Traditional TV application; if it is determined that any of the TV applications is a traditional TV application, apply for processing resources from the resource management service through the traditional application management service to process any of the TV applications; otherwise, the traditional application management service releases Applied processing resources; wherein, the traditional application management service is used to apply for or release the processing resources used to process the traditional TV applications, and the resource management service is used to manage the processing resources of the smart TV. Through the technical solution of the invention, the difficulty of developing traditional TV applications can be reduced, and the development time of traditional TV applications can be shortened. At the same time, resource conflicts caused by unreasonable resource allocation between traditional TV applications and intelligent applications can be avoided.

The invention relates to a preparation method for 1, 6-hexanediol modified polyester for hot shrink films. 1, 6-hexanediol, pure terephthalic acid and hexanediol are synthesized into polyethylene terephthalate 1, 6-hexanediol copolyester under catalysis of a compound catalyst by esterification and polycondensation reaction; the molar ratio of the hexanediol and the 1, 6-hexanediol is 40:60-90:10; the mole number ratio of the sum of the mole numbers of the pure terephthalic acid, the hexanediol and the 1, 6-hexanediol is 1:1.0-1.8; the catalyst is a composite catalyst of titanium compound, antimony compound, cobalt compound and germanium compound; and the melting point of the copolymer is 160-230 DEG C, the intrinsic viscosity is 0.55-0.75 d L / g, and the breaking elongation is larger than 100 %. The 1, 6-hexanediol modified polyester overcomes the defects of poor color and adhesion easiness, bending performance and tensile performance are improved, the melting point is reduced, post-processing performance is improved, and the 1, 6-hexanediol modified polyester can be used to process hot shrink films.

The invention discloses a technical method for improving the hiding power and hue fullness of nano-carbon black by adding water-soluble blue dye. The blue phenomenon of the system caused by the migration and surface enrichment of color dyes, and improve the storage stability of nano-carbon black, effectively prevent agglomeration, and enhance the dispersion performance of nano-carbon black.

The invention discloses a global image editing and dissemination method and system. The dissemination method includes the following steps: S1. Obtaining an original image and a stroke image edited by a user, the area covered by the stroke image of the original image is the calibration editing area, and the original image is not The area covered by the stroke image is the uncalibrated editing area; S2, for the pixel point i in the uncalibrated editing area, obtain the pixel block Ai corresponding to the pixel point i, and obtain the pixel block Bi with the highest similarity with the pixel block Ai in the calibrated editing area ' as the optimal matching pixel block of the pixel block Ai; S3. Propagating the user edit covered at the target pixel point i' corresponding to the optimal matching pixel block Bi' to the target pixel point i corresponding to the pixel block Ai. The method establishes a propagation scheme based on the global random pixel block matching information of the image, and propagates the existing editing scheme to the global image quickly, accurately and effectively.

A control device and a control method for a direct-type backlight source. The control device for a direct-type backlight source comprises: sensors (20) connected successively, a backlight control circuit (30), and a direct-type backlight source driving circuit (40). The sensors (20) are located between four light emitting units (101, 102) of the direct-type backlight source (10), and are connected with the backlight control circuit (30). The direct-type backlight source driving circuit (40) is connected with the light emitting units (101, 102) of the direct-type backlight source (10). Intensity of red light, green light, and blue light is detected and stored at a preset interval, and is compared with previously stored intensity of the red light, green light, and blue light to obtain an adjustment amplitude of a corresponding driving current. Then, a corresponding working current of the direct-type backlight source (10) is adjusted according to the adjustment amplitude of the corresponding driving current, and chroma of the direct-type backlight source (10) is adjusted. The control device and control method provided by the present invention can reduce the chroma excursion of display images, thereby maintaining qualitative shift of the display images.

The invention discloses a hyperspectral imagery interaction type multi-image color visualization method. The hyperspectral imagery interaction type multi-image color visualization method comprises step1, information screening; step2, node diagram ranking; step3, interaction type adjustment of three-channel information; step4, display in color space, normalization or image enhancement processing of three gray level images acquired in the step3, wherein the three channels used as the color space respectively used for displaying the acquired output images. The hyperspectral imagery interaction type multi-image color visualization method is advantageous in that an interaction interface is used to facilitate user operation; more information is expressed, and information of various types is displayed in a combined manner; the hyperspectral imagery interaction type multi-image color visualization method is used for the hyperspectral image, and is used for displaying the image information of other types, and integral color tone is adjusted according to requirements; the optimal output image is easily determined, and surface features or types are displayed in a prominent way.
