Plasma TVs provide high-quality images that need to be displayed on the display panel. However, the service life of plasma TV display panels has always been a bottleneck restricting the development of plasma TVs. Its panels generally produce significant brightness reduction after 10W hours, thus affecting Picture quality. At present, there is no technology that can solve this problem fundamentally. With the large price cuts of LCD TVs, the price of LCD TVs is approaching the psychological line of consumers, and the advantages of plasma TVs relative to LCD TVs are being broken. Compared to liquid crystals and traditional CRT TVs, the power consumption of plasma is amazing. Generally, the power consumption of a 40-inch plasma TV set is above 200W. The high power consumption will inevitably cause the body to heat up quickly. The huge heat dissipation of the plasma TV set is also a test for the overall manufacturing process of the product. Requirements are easy to age in high heat environments, so manufacturers need to have very strict standards for every component of plasma TV. Plasma TV screens have experienced roughly four stages of development in recent years. The first generation screen brightness is less than 550 nits, the contrast ratio is 500:1, the second generation screen brightness is 700 nits, the contrast ratio is 1000:1, the third generation screen brightness is 1000-1200 nits, and the contrast ratio is 3000:1 to 5000:1. The fourth generation screen brightness is 1300-1500 nits, and the contrast ratio is 10000:1. Now it has been updated to the fifteenth generation screen. At present, there are some plasmas below 10,000 yuan on the market. The price is low, which makes many consumers tempted, but according to relevant experts, due to the inventory of upstream display manufacturers, some manufacturers A large number of low-brightness, low-contrast plasma screens of the first and second generations are used to digest inventories. Usually these plasma screens are gray and the viewing effect is not good. Consumers must pay attention when purchasing, so as not to buy the market. product.
