LCD TV , Accounted for more than flat-panel TV market Qi Cheng, apparently has become mainstream, the family also used CRT TV're falling behind, not an LCD TV to catch up the trend of the! To choose a good LCD TV , A good Liquid crystal screen Important! So, how can buy the high cost of TV, is currently of great concern to most consumers. Today, we understand the fundamentals Hard Screen And soft screen differences, vigorously promote the store on the Purchasing Guide Hard screen really better? Allow consumers to make their own decisions. Hard screen with a simple distinction between the soft screen IPS (Hard screen) IPS technology (In-PlaneSwitching, flat conversion) is introduced in 2001, Hitachi LCD technology, commonly known as "SuperTFT". IPS camp, led by Hitachi, gather the LG D, HannStar Display and others. Greatest feature of this technology is its poles are in the same plane, unlike other LCD models in the top and bottom 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 transmission rate, the IPS used in LCD TVs will need more lamps, and in certain extent, the power consumption will be larger. Another drawback is the light leakage problem more serious, pure black is not enough contrast little worse than PVA, it must rely on the compensation of optical films to achieve better black. IPS screen has the advantage of the high viewing angle, to be fast, accurate color reproduction. And compared to other types of screen, IPS screen screen more "hard", and lightly water planning what patterns are not prone to deformation, so there is called a hard screen. VA (soft screen) Fujitsu's MVA technology (Multi-domain VerticalAlignment, multi-quadrant vertical alignment technology) can be said to be the earliest wide-angle LCD screen technology. Type of screen can provide a greater viewing angle, usually up to 170 °. The improved P-MVA class screen viewing angle up to 178 °, close to the current needs of consumers at home watching, the 8ms response time can achieve the following. Samsung Samsung Electronics PVA technology (Patterned VerticalAlignment) also belong to the VA technology category, which is the successor MVA technology and developers, the upgraded S-PVA and P-MVA has been able to keep pace. PVA with a transparent IT O electrode instead of MVA in the liquid crystal layer protruding objects, open and transparent electrode can get a better rate, minimizing waste of backlight. VA wide viewing angle technology, because of its strong production capacity and stable quality control system, widely used in high-end liquid crystal display or LCD TV. VA type panel is soft screen, and lightly similar waterlines will plan. Screen, hard and soft, non-sole criterion for purchase choice Currently using VA wide viewing angle technology, screen manufacturers have AUO Optoelectronics (AUO), Chi Mei Optoelectronics (CMO), Chunghwa Picture Tubes (CPT), Samsung and Sharp ; Use of IPS technology with IPS Alpha and LGD. The same occasion, using the same source, comparing two different view LCD TV, if there are significant differences in quality, then the key question should be the level of the LCD screen performance with the core driver, not the soft screen hard. Therefore, the hard-and soft-screen display reasonable explanation, only the manufacturer's production process characteristics, although different, but also remain the same. Hard-and soft-screen display is the same physical properties, as long as no sharp objects or gravitational impact characterization, not easy to injury. Appliance industry experts believe that, whether in hard or soft-screen display, LCD TV products can not determine the quality, choice should not be the sole criterion for consumer purchase. Hard-and soft-screen display in the production process although there are some differences, but in performance and there is no absolute good or bad. The former leaked contrast difference, which side to see color distortion, but the hard-and soft-screen display manufacturers have been gradually improved towards their own shortcomings, nothing is impossible, a good hard screen, soft screen poor fallacy in modern natural flow of information is not our attack broken.
