When it comes to TV, you can't help but mention plasma TV. What is a plasma TV? The reporter interviewed the professionals of Panasonic TV. Plasma TV, also called PDP (plasmadisplaypanel) TV, is an active light-emitting type plate that uses inert gas to generate gas discharge under a certain voltage, forms a plasma, emits vacuum ultraviolet light and then excites three primary color photoluminescent phosphors to emit visible light. Display device, each pixel is independently illuminated for imaging. The main technical indicators of plasma TV are: First, resolution resolution is the basic technical indicator of TV. Plasma TV is divided into standard resolution and high resolution according to resolution. The standard resolution is 852 & TImes; 480, which is sufficient for the current signal. But for high-resolution 720p and 1080i digital signals, it is not enough. Second, contrast and brightness Contrast and brightness are important indicators of plasma TV. The higher the brightness of the plasma TV, the smaller the influence of the brightness of the surrounding environment, and the TV program can be clearly watched even in a bright environment. Third, the perspective of the current plasma products on the market basically have a viewing angle of more than 160 degrees, which will not cause any viewing obstacles for users to watch. Fourth, the dynamic definition of the user is mainly used for watching TV or disc, the images played by them are dynamically changed, and the characteristics of the plasma determine the TV whose dynamic resolution is higher than other imaging principles. Advantages of plasma TV: one. The body is light and thin. A 32-inch TV body is about 20 inches thick. A 60-inch plasma TV is about 5 inches thick. It can also be wall-mounted and weighs half the weight of traditional TV. two. The large-screen traditional TV screen can reach up to 40 inches, while the plasma TV screen can reach 63 inches (the current technology can be even larger). three. The ultra-wide viewing angle plasma TV has a viewing angle of 160 degrees and can accommodate more people to watch. four. The pure flat distortion-free plasma is completely flat-panel display, and the structure of each light-emitting unit is the same, so there is no image geometric distortion such as trapezoidal distortion, linear distortion and pincushion distortion which are common in the picture tube. Fives. Plasma TV without electromagnetic interference itself has no electromagnetic structure, so it will not be interfered by electromagnetic interference. Speakers, high-voltage electricity and even magnetic fields will not cause any interference to it, so it will obtain more stable image quality. six. Uniform brightness The traditional CRT technology has a thermal halo problem, that is, the brightness is uneven in the center of the picture and the four corners. Since each pixel in the plasma display can emit light independently, it is very uniform, there is no bright area or dark area, so there will be no The above problem. Seven. A non-electromagnetic radiation plasma display is different from a CRT in that it does not use scanning, so there is no flicker, and there is no electromagnetic radiation, which will not cause damage for a long time. Eight. High brightness and contrast Compared to CRTs and projectors, it has high brightness and contrast, even in outdoor glare, it also has a very clear picture, suitable for outdoor display. nine. Full digital display Most brands now support DVI (Digital Video Interface), which can reduce the distortion caused by analog signals. ten. Durable and large plasma display manufacturers around the world have developed this technology for about 50,000 hours. It is generally estimated that the actual life expectancy is about 30,000 hours. Calculated for 8 hours per day, for up to 10 years
LED Tube light brightness is especially more soft and make it easy for people to accept.Using CREE, wafer chip as light-emitting semiconductor materials, placed in heat dissipation material, then add cooling casing and stable quality of professional power, protect the internal core, and common fluorescent lamp shape almost tubes, can replace ordinary fluorescent lamps and lanterns.
The Common Led tube light are T8.T5 Led tube light. Two sizes are 1 inches and 5/8 inches diameter. The length of the Led tube light are 60cm.90cm.120cm.
