subject: Note You Buy Lcd Tv Lcd Panel [print this page] LCD TV Has replaced the previous CRT TV into the mainstream market, the recent "
Golden Week "And the football
World Cup The impact of the price of LCD TVs dropped lower and lower, 30-40-inch LCD TV has also been the focus of the consumer to buy television, and how we can choose to a good LCD TV? Of course, first look at its
Panel , Because the panel will have a direct impact on the viewing screen, and LCD TV panels account for more than half the cost of the whole machine, is affecting the cost of LCD TV a major factor, so to choose a good LCD television, first selected its panel. LCD TV panels are those then? Estimated that many people do not know, I would speak for our web
Home Appliances The vast network of friends introduce LCD TV panels, so that everyone in the time to buy LCD TV can make better choices.
Now LCD panel The manufacturer mainly Sharp,
Samsung , LG - Philips, AU Optronics, Chi Mei
Electronic , BOE And so on. Wide viewing angle LCD panel technology is divided into TN + Film (soft screen) camp, IPS (hard screen) camp and the VA (soft screen) camp. Between them, it is different, we now come to take a closer look.
1, TN + Film view extended membrane (soft screen) this technology is still based on conventional TN mode liquid crystal, but an increase in the manufacturing process, a foil process. TN + Film Wide-angle technology is characterized by the largest low-cost, technology access, low threshold, widely used. In general, TN panels are advantages and disadvantages are obvious products, cheap, low output gray series, the liquid crystal molecules tilt speed, cause its easy to improve response time, response time to meet the game requirements is that it the advantages, not the ideal viewing angle and true color performance of its obvious disadvantages. So now sold in the market use TN LCD panel
Monitor Widely used improved the TN + FILM (compensation film) to cover TN panel viewing angle limitations, while color jitter which make the use of technology can only display 260,000 colors obtained 16.2M TN panel display capability.
Second, IPS (In PlaneSwitching plane control mode) wide viewing angle technology (hardware screen) the best selling points is its poles are in the same plane, unlike other LCD models are up and down both sides of the electrode, three-dimensional arrangement. As the electrode in the same plane, no matter what state the screen of liquid crystal molecules are always parallel to the aperture ratio will decrease the light transmittance, so the IPS used in LCDTV will need more backlight. PVA restore it little worse than black, so need to rely on the optical compensation film to achieve a better black; IPS mode liquid crystal display has a feature that is inclined 45 degrees to observe if TN will see a similar pattern reversal as grayscale, you can determine IPS as a symbol. IPS also has a slower response time and contrast more difficult to improve the shortcomings.
