Abstract: A method for making iridium oxide nanoparticles includes dissolving an iridium salt to obtain a salt-containing solution, mixing a complexing agent with the salt-containing solution to obtain a blend solution, and adding an oxidating agent to the blend solution to obtain a product mixture. A molar ratio of a complexing compound of the complexing agent to the iridium salt is controlled in a predetermined range so as to permit the product mixture to include iridium oxide nanoparticles.

Abstract: An edge-lit backlight module according to this disclosure includes a frame body and a light-emitting unit. The frame body includes a bottom portion, a wall portion and at least one first positioning portion. The wall portion is connected with the bottom portion, and the first positioning portion is located at least one of the bottom portion and the wall portion. The light-emitting unit includes a circuit board and a plurality of light-emitting elements disposed on the circuit board. The circuit board includes at least one second positioning portion. The second positioning portion includes a notch and an extension portion extending from the circuit board. The first positioning portion and the second positioning portion engage with each other to connect the light-emitting unit with the frame body.

Abstract: Antivirus software detects malware on a computer and the landing time of the malware is determined; a time window around the landing time is determined. Optionally requiring the landing time of the malware to be before the installation time of the antivirus software eliminates false positives. Any files of the computer systems that have a creation time within the time window are suspect. If the prevalence value and the maturity value of the suspect file are below respective thresholds then it is concluded that the file is malware and it is deleted. No virus signature or virus pattern that matches the deleted file need be relied upon or used. The detected malware may be the original mother file or a dropped file. An online prevalence and maturity database is used. The launching time of the malware may be used instead of the landing time.

Abstract: The present invention relates to a fixing structure for printed circuit board of backlight module. It includes a protective cover having at least one first supporting portion and the first supporting portion having a first protrusion; a printed circuit board having at least one pierce hole; and a back plate having at least one second supporting portion and the second supporting portion having a second protrusion, wherein the first supporting portion and the second supporting portion oppositely support the printed circuit board, the first protrusion and the second protrusion oppositely wedge in the pierce hole, and two copper areas respectively surround two ends of the pierce hole and electrically connect with the first supporting portion and the second supporting portion. The present invention economizes the cost of using screws and eliminates the static electricity from the printed circuit board of the backlight module.

Abstract: A direct type backlight module including a frame, a plurality of light sources, an optical plate and an upper frame is provided. The frame includes a bottom frame and a side frame extending upward from the edge of the bottom frame. The light sources are disposed on the bottom frame, and the optical plate is disposed on the side frame above the light sources. The frame and the upper frame are assembled, wherein the optical plate is located between the upper frame and the frame. The upper frame has at lease one protrusion located above the optical plate and protruding to the optical plate. Therefore, the deformation of the optical plate can be reduced.
