Plasma (PDP) TV Compared with traditional CRT TVs, the most prominent feature of PDP TVs is “big and thinâ€. Other features are also shown in:
(1) Thin and light structure
Due to the thin and light nature of the PDP display module, the overall structural characteristics of the display screen are determined, and the increase of the display size does not require correspondingly increasing the thickness of the screen body.
(2) Wide view
The PDP can achieve the same wide viewing angle as the CRT, up and down and above 160 degrees. The liquid crystal (LCD) generally has a viewing angle of 120 degrees in the horizontal direction and less in the vertical direction.
(3) Anti-electromagnetic interference
Due to the difference in display principle, electromagnetic interference from the outside, such as motors, speakers, etc., has little effect on the image of the PDP. In contrast, CRTs are much more disturbed by electromagnetic fields.
(4) The image is not distorted
The RGB grid of the PDP is evenly distributed on the plane, while in the flat CRT the inner surface is not flat, which causes typical pincushion distortion. And when the local brightness of the picture is not uniform, the CRT will often produce corresponding image distortion, which is not the case with PDP.
(5) Convergence and focus
Plasma TVs are high-tech and state-of-the-art electronic products. They are relatively unfamiliar to many customers. Many people are careful when they use them because they don't understand the principle, so they can't fully enjoy the enjoyment of plasma TVs. In fact, the life of a plasma TV is about twice that of an ordinary TV. If the life of an ordinary TV set is 10 years, then the plasma can be used for about 20 years, and the plasma TV is superior to the ordinary TV in many aspects such as display, color, appearance, etc., so the plasma TV is the development of the future TV. direction.
In use, it is the same as using ordinary TV. Generally, you don't need to pay special attention to it (unless it is stated in the manual). Because the mirror of plasma TV has a special coating, do not use water or chemical solution to wipe the mirror when cleaning. Wipe with a clean soft cloth to avoid damage to the mirror surface by other substances.
Disadvantages; because R, G, B phosphors self-illuminate, and display images in fixed pixel addressing mode, when displaying high-brightness, high-contrast still images for a long time, residual images are likely to occur, and even burnt screen phenomenon occurs. Therefore, when watching TV, the TV brightness and contrast should be reduced as much as possible without affecting normal viewing. Plasma and liquid crystal (PDP) and liquid crystal (LCD, LED) TV comparison plasma and liquid crystal are the mainstream technology of contemporary TV sets, representing two different development directions. Both flat-panel TVs have their own advantages and disadvantages. Plasma color TV has the characteristics of no flickering, thin thickness, light weight, vivid color, vivid image, etc., and it is relatively easy to enlarge the screen. The disadvantage is that it is slightly heavier than LED TV.
LCD TVs also have the characteristics of imageless flicker, thin thickness, light weight, etc., and LCD screens have been widely used in the PC field, but in the large screen, LCD technology lags behind plasma, and large-screen LED TVs have higher cost and easy viewing. Affected by the perspective.
Size/price ratio
LCD and plasma TVs are not cheap. Relatively speaking, plasma TVs have an advantage over LCD TVs in terms of unit price per square inch. From the color TV store in 2010, LCD TVs are 22-65 inches in size and cost 2,000-20,000. Plasma mainstream products are large screens with dimensions of 40-58+ inches (Panasonic has 103-inch products 580,000). ), mainstream products are priced from 4,000 to 70,000.
performance
In terms of home theater effects, plasma TVs are more effective than LCD TVs. Experts explained that because LCD TVs usually cannot display the blackness of plasma TVs. Therefore, LCD TVs are difficult to display more details, and video players will feel that the "stereo" of the images is not very good.
Service life / power consumption
LCD, LED TV and plasma TV have become almost the same through recent technological improvements in terms of service life and power consumption.
Burning screen and altitude problems
The problem of "burning the screen" has been improved by the latest technology, and this problem does not exist in plasma TVs; LCD TVs do not have this problem. In addition, plasma TVs may have problems at high altitudes (good brands such as "Panasonic" plasma TVs will not), because the difference in air pressure at different altitudes will cause a plasma TV to make a buzz. LCD TVs will not have this problem.
High definition
Most plasma TVs and LCD TVs can display high definition signals. However, it should be noted that to enjoy true HD TV, the display resolution should be at least 1280×720. Up to now, 80% of the plasma can reach the physical resolution of 1080P (that is, "Full HD"), and almost all LCD TVs larger than 22 inches can achieve the "Full HD" effect.
Computer and video games
Most plasma TVs and LCD TVs can be used as computer monitors, and many TVs even offer a DVI interface for better display performance. There are no problems with both TV game consoles. From a performance point of view, it is difficult to make a ruling on the two technologies, because both are almost the same according to the latest technological improvements.
Hand Automatic Cutting Machine
Fast and accurate
The latest cutting technology, such as intelligent speed adjustment, provides fast and accurate cutting. Select the hardness of the material to be cut and the machine will automatically set the correct speed.
When the cutting wheel is blocked by the cleared material, the choice is between automatic direct cutting mode, which uses constant feed rate or impact cutting. ExciCut Manual cutting mode is used for cutting harder and larger workpieces. The automatic X cutting table option allows the user to access a multi-knife cutting mode to cut slices of the same or different thickness, or to cut precisely at a specified position.
Multi-function knob for setting cutting process parameters quickly and easily. Automatic speed Settings save time and allow users to apply the same cutting wheel for different materials to avoid time-consuming cutting wheel change operations. The mobile cutting arm locking system quickly switches between manual and automatic cutting and gives you a complete overview of all the necessary information based on the color display of the icon.
