<br> LCD TV, is now mainstream and purchase of home appliances, how you can choose to a fit and superior LCD product? for this purpose, small series collection put together the following 11 points on LCD TV buying guide of integrated indicators, hope .you have a reference to the role. <br> <br> 1. see after-sales service guarantee <br> <br> Although the LCD screen is not easy, but if there is a problem, maintenance is a very troublesome thing. .Most manufacturers offer 1 to 3 years of warranty service, some manufacturers even offer free on-site service and warranty repair costs relief, these are small details best ask before purchasing. <br> <br> 2. determine the pixel <br> < .br> LCD screen of the most common problem is "bad", while many products claim that their product "pixel", but vendors assessing bad point standards, some manufacturers offer as long as there are bad points for the new service, there must be .in accordance with the relevant assessment criteria to judge whether the product has long experience bad point is a product defect or several points above is considered bad points are the evaluation criteria? ask clear, that the rights of damage. Generally high quality of the LCD TV .on pixel number is strictly controlled. <br> <br> 3. Select the screen should not be too large <br> <br> Traditional TV display in specification Gakko 17 inches, but the Panel around 1 inch or so cannot be used to .display the actual Visual size of only about 15 inches. While the LCD Panel identified 15 inches, the actual Visual size is 15 inches. Consumers when buying choice should be based on the room size, suitable dimensions so that the screen is too large but cause .pressure. If the living room 30 square meters in area, select the 32 inch LCD TV. <br> <br> 4, the Visual angle <br> <br> Sin is currently available in the LCD monitor, the Visual angle is symmetrical .(that is, from the left or right you can see the angle of the images on the screen are the same. For example on the left to 60 degree Visual angle, the right must be the Visual angle 60 °). And up and down .the Visual angle is usually less than about Visual angle. From the user's standpoint, of course, the greater the Visual angle, the better. <br> <br> Choice of 5, brightness <br> <br> Brightness refers to the degree .of bright screen, the unit is cd/m2 or nits. Currently increasing the brightness of two ways: one, enhances the LCD Panel of photo-through rates; another is to increase the brightness of the backlight source. <br> <br> .Brightness too low is not conducive to clear expression of a video screen, for some dark scene would be powerless. In addition, the screen's brightness uniformity is also very important, but in LCD TV product specifications, typically do not. Brightness uniform or not, .and back light and reflector of quantity and quality of the configuration is closely related to the way better TV, screen brightness uniformity, no clear light areas. This, in the screen to switch to a black screen, more easily captured the uneven brightness. < .br> <br> 6, color selection <br> <br> LCD can express a wide color gamut than CRT, so if the color from the real performance object to compare, the LCD TV is no CRT TV. When buying a LCD TV ., select more colors adjustment feature models to their own tune out closer to the natural color of the image. <br> <br> 7, note the contrast <br> <br> General entry models screen contrast most 300: 1, intermediate model .450: 1, 500: 1 level, if the actual comparison entry, graphic display of the high-order model, has a high-contrast screen color of layer effect will be more obvious, color performance more lively, rich, this mainly look at .the needs of users. <br> <br> 8, shall not be greater than 16ms response time <br> <br> Because imaging, LCD TV display response time too long, the embodiment of the image that is prone to motion blur and .smearing of the image, this is a dynamic image-based film and TV is very negative. This indicator is, of course, the smaller the better. After all the main LCD production enterprises, at present most of the TV with LCD screens are done .about 16ms response time, and their appreciation for the TV show has been basically does not constitute a problem. <br> <br> 9, image resolution <br> <br> The resolution of the LCD TV is fixed, please remember to not .like computer LCD display, you can adjust the resolution. LCD TV's fixed resolution but also its best resolution, high resolution, can easily be compatible HDTV. For anyone not LCD best resolution of the video signal to the LCD TV will need to convert the image .resolution and then displays the converted. <br> <br> For LCD TVs, the resolution is one of the important parameters. Traditional CRT TV resolution supported by a more flexible, and LCD TV with pixel spacing has been fixed, so the supported display .modes, unlike CRT TV so much. LCD TV's best resolution, also known as maximum resolution, the resolution of the LCD TV to show the best image. <br> <br> LCD TV rendering resolution lower display mode, there are two ways to .display. The first is centered: for example in XGA1024 × 768 screen display screen SVGA800 × 600, only the screen Center 800 × 600 pixel is rendered, the other has not been rendered remained dark pixels, this method is less. Another known as extended .display: display below the optimal resolution of the screen, each pixel by interpolation to adjacent pixel display, so that the entire screen be filled, but this will reduce the original sharpness and color. <br> <br> At present there are LCD TVs .800 × 600 and 1280 × 768 and 1366 × 768 resolution of several common. <br> <br> 10And the screen refresh rate <br> <br> For LCD monitors, the refresh rate and does not cause the screen to flicker. Refresh .rate in 60Hz, LCD they can get a good picture. In the LCD monitor, each pixel will continue to glow until light signal was sent to the controller, LCD monitor does not have the result of continuous charging and discharging of flashing phenomenon. <br .> <br> 11, life no less than 5 million hours <br> <br> There are some cheap LCD TV life is very short, so pay special attention to. Backlight lamp of life is the life of the LCD television, LCD television .with backlight life in 5 thousand hours. In other words, if you average daily use LCD TV 5 hours, that 5 000 hours of life mean that you can use the LCD TV 27 years. <br> <br>.
