A display device is capable of efficiently cooling electronic or electrical components disposed therein without installing a cooling element or member on the electronic or electrical components. In the display device, a ceramic or ceramic-containing layer is formed on any one of a surface of a member placed in proximity to the electronic or electrical component, the surface facing at least the electronic or electrical component, a surface of the member placed in proximity to the electronic or electrical component, the surface opposite to the surface facing the electronic or electrical component, a surface of the electronic or electrical component, and a surface of a circuit board, the surface opposite to a surface of the circuit board on which the electronic or electrical component is mounted.

The invention discloses information synchronization method and system, a set top box and a server in an IPTV (Internet Protocol Television) system, wherein the method comprises the following steps that the server acquires a system check word according to the user information and the channel information of the server side; the set top box receives a response message returned by the server and containing the system check word; the set top box generates a local check word according to the user information and the channel information cached in local, and the system check word is matched with the local check word; and when the system check word is not matched with the local check word, the set top box sends a synchronization request to the server, downloads the user information and the channel information from the server and caches the user information and the channel information. The invention can know whether the information cached in local is up to date or not according to the system check word in the response message issued by the server; and if not, the synchronization request is issued in time for updating. The scheme does not have great influence on the performance of the EPG (Electronic Program Guide) server.

The invention discloses a processing technology of a metal face frame of a liquid crystal television, and the processing technology comprises a processing procedure of folding edges and a processing procedure of ambient round angles. The processing technology is characterized in that an aluminum sheet with a cut in the middle is fixed between a concave pattern plate and a fixing plate in the processing procedure of folding edges, wherein the edge of a concave pattern cavity of the concave pattern plate is added with a ring of pressed rib pressed into the aluminum sheet, and the inner edge of the aluminum sheet is pressed by a convex pattern plate to form the folding edge; in the processing procedure of ambient round angles, three pairs of concave-convex pattern insert block components are adopted to bend, punch and shape the four round angles at the connecting places of the four straight edges on the folding edges in three steps, and the radiuses of the arc surfaces on the three convex pattern insert blocks of the concave-convex pattern insert block components are decreased sequentially. The processing technology of the invention can press the folding edges with smaller round angle radius and the four round angles at the connecting places of the four straight edges on the folding edges, and effectively prevent rupture at the four round angles in the processing course, which improves the product quality greatly.

A system that simultaneously prints digital image files' images and image files' internal metadata. The details for a digital image may be printed onto the front side and / or back side of a picture's printed hardcopy while simultaneously printing the digital image file's internal metadata or simultaneously displaying the digital image with its file's internal metadata on electronic media such as televisions, desktop, laptop and tablet computer screens, digital picture frames, cell phone, smart phone and telephone displays, public billboards, Internet web pages and x-ray photographs. The digital picture's details, being presented in the subject system as a file's internal metadata, include but are not limited to the picture's file name, the photographer's name, a copyright holder's name and a description of the picture, as well as the picture's technical details such as its image format, date, GPS location, focusing mode, metering mode, shutter speed, flash exposure compensation, resolution, ISO sensitivity, white balance, etc. A unique image identification code, password protection and encryption, can be assigned to each image and incorporated in the image file's internal metadata.
