College】 【weak flat-panel TV to buy depends on "physical resolution" --- Power By 【China】 weak home network.

<br> Following the 2004 DLP and LCD projectors after World War II, 05 flat panel TV LCD TV and plasma TV phone-in was underway, especially from the "May Day" golden week to now, manufacturers launched models of flat-panel TV brand .range, so that consumers get confused and disoriented. .Author based on many years of work experience and practice, LCD TV and plasma TV in the performance comparison, combined display can receive digital TV will begin broadcasting high-definition TV programs and other issues talk about some of the views for the consumers. .<BR> <BR> "Physical resolution," Identification of high-definition <BR> <BR> digital television (including satellite digital television broadcasting, cable digital television transmission, terrestrial digital TV broadcasting) in 2005 and 2007 have been launched, consumer .who can show HD programming to choose the image LCD TV or PDP TV. .So, how to identify market sales of LCD TV and PDP TV is HDTV? .<BR> <BR> LCD TV and PDP TV are fixed resolution TV, has a physical resolution (ie pixels) of the points, screen size, pixel count is to determine whether the image shows an important basis for high-definition (of course, and circuit .related). .<BR> <BR> 42-inch PDP TV market, most of the physical resolution is 852 × 480 or 1024 × 768, if the display high-definition image resolution is 1920 × 1080, Amplitude ratio of 16:9, the image is displayed .HDTV resolution difficult to achieve the requirements, that is, the horizontal and vertical resolution of 720 TV lines or more. .However, high-definition images can be supported or compatible, and manufacturers and merchants to call this 42-inch HD PDP TV machine. .<BR> <BR> More than 50 inches for PDP TV, mostly the physical resolution of 1366 × 768, a few have 1920 × 1082, can display high definition images, but 1280 × 720 of the PDP TV, if the circuit transformation, motivation circuit .better high-definition images can also be displayed. .Recommend that consumers choose to buy PDP TV screen 50 inches or more, the physical resolution of 1366 × 768 or more in, but the price to be expensive. .Large price cut 42-inch television, most did not give instructions on the physical resolution, but also can display the individual is given in standard definition image resolution of 852 × 768 physics. .<BR> <BR> LCD TV screen size from ten inches to 65 inches there. .20-inch LCD television is generally following an early production line, the technology is relatively backward, response time, the physical resolution, viewing angle, contrast, brightness, and other poor performance, for the PC to display the teletext screen, the image does not display video .ideal, although the price down so low, in the purchase to be carefully considered. .The 25-inch to 30 inch LCD TV, general physical resolution is 1024 × 768 or 1280 × 720, can support high-definition image display, image resolution better than small-screen LCD TV, but sports a larger image trailing; for 32-inch .-37 inch LCD TV, most of the physical resolution is 1366 × 768, can display high definition images, but a few 37-inch LCD TV, the physical resolution of 1920 × 1082, horizontal and vertical resolution up to 1080 TV lines. .For more than 40-inch LCD TV, basically 1920 × 1082, but the price is expensive, so that consumers stay away. .LCD TV high-definition still images, but there is motion smearing the image, when viewing moving images through the brightness level of sense and as PDP TV. .<BR> <BR> Also depends on the TV interface, the general must have the Y, PB, PR input interface and DVI (digital video input interface) port, preferably also has HDMI (High Definition Multimedia Interface, than the Y, PB, .PR and DVI interfaces are more powerful) and digital audio and video interface. .Should be noted that, although some domestic brand TV with DVI or HDMI interface, but its poor performance, in the performance of foreign brands than domestic brands. .<BR> <BR> Election on demand <BR> <BR> LCD flat-panel TV and PDP TV sets have advantages and disadvantages, choose what kind of television, according to consumer demand. .<BR> <BR> Do not care about the money for the consumer, the manufacturers of top-level products can anything and everything, choose LCP TV and PDP TV are not the point. .But the purchase of 50 inches above the TV, could focus on the PDP TV. .For the salaried class, purchasing products, according to demand. .If you buy 42-inch LCD TVs under the proposed 32-inch -39 inch choose if to buy 25-inch to 30 inches, will have to consider the physical number of pixels can display high-definition images. .<BR> <BR> If the room is large, complex lighting conditions, choose the 50-inch PDP TV is better than the 50-inch LCD TV, now are cheaper in price. .If only in the bedroom, usually look at news or drama, consider 25-inch LCD TV around. .In short, for the majority of consumers, according to their needs and financial situation, after the actual inspection, or to the relevant expert advice, you will be able to buy a flat-panel TVs satisfied. .<BR> <BR> Links <BR> <BR> LCD TV and PDP TV advantages and disadvantages compared <BR> <BR> LCD TV advantages: <BR> <BR> 1.LCD TV, PDP TV screen size for more than like .of, from a few inches to 65 inches (currently do) have. .<BR> <BR> 2. Physical resolution has to do 1920 × 1080, the horizontal and vertical still images up to 1080 TV lines resolution, image detail, clarity. .<BR> <BR> 3. The image of high brightness, better than the CRT TV and PDP TV. .<BR> <BR> 4. The image is almost no distortion, because the screen size of diverse applications in the computer better than the CRT and PDP. .<BR> <BR> 5. Can be flat, thin, light volume, low power consumption. .<BR> <BR> 6. Afterimage image smaller. .<BR> <BR> 7. No radiated interference, image flicker-free, long-term viewing without eye fatigue better than the CRT TV. .<BR> <BR> LCD TV disadvantages: <BR> <BR> 1. Small viewing angle, brightness, contrast and saturation decreases with increasing angle, chroma error increases as the angle increases, .the image quality decreases. .<BR> <BR> 2. In all displays, the slowest response time, so watch the moving images, especially fast moving images, the resolution dropped. .<BR> <BR> 3. Contrast, on-off ratio (full white / full black contrast) worse than the PDP TV. .<BR> <BR> 4. Due to use of backlight, easy to produce light leakage, full-screen brightness uniformity is poor, worse than the PDP TV. .<BR> <BR> 5. For a fixed resolution of the imaging device, when the image signal format and display the same time, the need for format conversion, bringing the image quality decreases. .<BR> <BR> 6. On the big screen size, though better than the CRT TV, but inferior to the PDP TV, when the size is larger, higher prices. .Currently on the market 32-inch 42-inch LCD TV and PDP TV prices almost the same. .<BR> <BR> 7. There is no high-quality flat speaker support. .<BR> <BR> PDP TV advantages: <BR> <BR> 1. In the direct-view flat panel TV, the screen size can do the most, now be 100 inches, which is a CRT TV, LCD TV unparalleled .The. .<BR> <BR> 2. Image clarity, color reproduction is good, bright colors, high contrast, on-off ratio (full white / full black contrast) high, in the dark field, the image-level good. .<BR> <BR> 3. With flat panel TV's most wide angle and very dark black. .<BR> <BR> 4. Short response time, moving images better than LCD TVs trailing. .<BR> <BR> 5. Full-screen brightness uniformity is good, better than the LCD TV. .<BR> <BR> 6. With the maximum, the thinnest flat-panel displays, small size. .<BR> <BR> 7. Image without blinking, the eyes do not fatigue long-term view, better than the CRT TV. .<BR> <BR> PDP TV disadvantages: <BR> <BR> 1. Maximum peak brightness and dynamic range of the average image brightness changes with the change. .<BR> <BR> 2. Because there was space between pixels, resulting in pixels of the image to see more clearly at close range. .<BR> <BR> 3. When the signal format and display the image at the same time, the need for format conversion, image quality decreases. .<BR> <BR> 4. Size should not be less inconvenient for computer applications, flexibility on the inferior LCD. .<BR> <BR> 5. Useful to the average maximum peak brightness and low brightness. .If the images at high brightness, high power consumption, lower life expectancy. .<BR> <BR> 6. At 50 inches, the number of pixels is not easy to do high-definition display images is poor, worse than LCD. .<BR> <BR> 7. In high pressure, high current, a larger number of assembly parts, and more for the high-voltage components and electromagnetic interferences. .<BR> <BR> 8. Afterimage larger image, is inferior to LCD TV and CRT TV. .<BR> <BR> 9. Because of small size, there is no support for high-quality flat speaker, the sound fidelity is poor. .<BR>.
