FAQs (Frequently Asked Questions)a hub allows connection to another hub or device, such as a USB keyboard, cameraor printer.Q: What can I do if my USB peripherals don't work with the USB hub of my monitor?A: If you experience the problem, just detach and re-attach the USB hub cablebetween PC and your monitor, then refresh your PC device manager (Start > Setting> Control panel > System > Hardware > Device manager > Refresh) or reboot yourPC and the problem can be solved by above procedures.RETURN TO TOP OF THE PAGELCD Panel TechnologyQ: What is a Liquid Crystal Display?A: A Liquid Crystal Display (LCD) is an optical device that is commonly used todisplay ASCII characters and images on digital items such as watches, calculators,portable game consoles, etc. LCD is the technology used for displays in notebooksand other small computers. Like light-emitting diode and gas-plasma technologies,LCD allows displays to be much thinner than cathode ray tube (CRT) technology.LCD consumes much less power than LED and gas-displays because it works on theprinciple of blocking light rather than emitting it.Q: What differentiates passive matrix LCDs from active matrix LCDs?A: An LCD is made with either a passive matrix or an active matrix display grid. Anactive matrix has a transistor located at each pixel intersection, requiring less currentto control the luminance of a pixel. For this reason, the current in an active matrixdisplay can be switched on and off more frequently, improving the screen refresh time(your mouse pointer will appear to move more smoothly across the screen, forexample). The passive matrix LCD has a grid of conductors with pixels located ateach intersection in the grid.Q: What are the advantages of TFT LCD compared with CRT?A: In a CRT monitor, a gun shoots electrons and general light by colliding polarizedelectrons on fluorescent glass. Therefore, CRT monitors basically operate with ananalog RGB signal. A TFT LCD monitor is a device that displays an input image byoperating a liquid crystal panel. The TFT has a fundamentally different structure thana CRT: Each cell has an active matrix structure and independent active elements. ATFT LCD has two glass panels and the space between them is filled with liquidfile:///D|/My%20Documents/dfu/200P7/english/200p7/safety/saf_faq.htm (6 of 8)2006-12-11 1:16:19 PM
