.
although LCD screen is not easy to have problems.
but if there is a problem, maintenance is a very troublesome thing.
most manufacturers provide warranty services ranging from 1 to 3 years.
some manufacturers even provide free door-to-door service and maintenance fee reduction within the warranty period. It's better to ask for these details before purchasing.
.

2 Judging bad points.
.
the most common problem of LCD screen is "bad points"
although many products claim that their products have "no bad points", different manufacturers have different evaluation standards for bad points. Some manufacturers provide new services as long as they have bad points, and some have to judge according to the evaluation standards of camera. How long does it take for a product to have bad points? Or more than a few points are considered bad points? These evaluation criteria should be clear, so as not to damage the rights and interests.
generally, high-quality LCD TVs have strict control over the number of bad spots.
the number of bad spots in LCD TVs is very low
3. The screen should not be too large.
.
the traditional TV display screen is advertised as 17 inches in specifications.
however, there is about 1 inch around the panel which can not be used for display, The actual visual size is only about 15 inches.
and the LCD screen indicates 15 inches.
the actual visual size is 15 inches.
when buying a machine, consumers should choose the appropriate size according to the size of the room.
to avoid the pressure caused by too large screen.
if the living room area is about 30 square meters.
choose a 32 inch LCD TV.
.
4 Viewing angle.
.
for LCD displays on the market at present, the viewing angle is left-right symmetrical (that is, the viewing angle of the image on the screen can be seen from the left or right is the same.
for example, the viewing angle on the left is 60 degrees.
the viewing angle on the right must also be 60 degrees).
the viewing angle on the up and down is usually less than that on the left and right.
from the user's perspective From the point of view,
of course, the larger the viewing angle, the better.
.
5. Brightness selection.
.
brightness refers to the brightness of the screen.
the unit is cdgm2 or nits.
there are two ways to improve the brightness: one is to improve the light transmittance of the LCD panel; the other is to improve the brightness of the LCD panel; The other is to increase the brightness of the backlight source.
.
.
too low brightness is not conducive to the clear display of the video picture.
for some dim scenes, it is even more powerless.
in addition.
the brightness uniformity of the screen is also very important, but it is usually not marked in the specification book of LCD TV products.
whether the brightness is uniform or not.
in addition, the brightness uniformity of the screen is also very importantThe number of backlights and reflectors is closely related to the configuration mode. For better quality TV, the picture brightness is uniform, and there is no obvious bright area.
this point.
when the picture is switched to the black screen state, it is easier to capture the uneven brightness.
.
.
6 Color selection.
.
the color gamut of LCD is not as wide as that of CRT.
therefore, LCD TV is not as wide as CRT TV from the perspective of real object color.
when buying LCD TV.
choosing models with more color adjustment functions is conducive to adjusting images closer to natural colors.
.
.
7 Pay attention to the contrast.
.
the screen contrast of the general entry-level models is mostly 300:1.
the medium-level models have 450:1 and 500:1 levels. If you compare the image display ability of the entry-level and high-level models, and have a high contrast screen, the gradual effect of color will be more obvious, and the color performance will be more lively and rich, which mainly depends on the needs of users.
.
8 The response time should not be more than 16ms.
.
due to the limitation of imaging principle.
the display response time of LCD TV is too long, which is easy to appear residual shadow and trailing of moving image, This is very unfavorable for the film and television programs based on dynamic images.
of course, the smaller the index is, the better.
through the efforts of major LCD manufacturers.
at present, most of the LCD screens used in TV have achieved a response speed of about 16ms, which basically does not constitute a problem for the appreciation of TV programs.
.
.
9 The resolution of LCD TV is fixedPlease remember this! It's not like a computer LCD, The resolution can be adjusted.
the fixed resolution of LCD TV is also its best resolution.
high resolution can be easily compatible with HDTV.
for any video signal that is not the best resolution of LCD screen.
LCD TV needs to convert the image resolution before display conversion.
.
.
for LCD TV.
resolution is one of the important parameters.
for LCD TV, resolution is one of the most important parameters>The resolution supported by traditional CRT TV is more flexible.
however, the pixel spacing of LCD TV has been fixed, so it does not support as many display modes as CRT TV.
the best resolution of LCD TV.
also known as the maximum resolution, The LCD TV can show the best image.
.
.
when the LCD TV presents the display mode with low resolution.
there are two ways to display.
the first one is the center display: for example, in XGA 1024 × The SVGA 800 is displayed on the screen of the 768 × 600.
only 800 in the middle of the screen × At present, this method is rarely used.
another method is called extended display: when the image is lower than the best resolution.
each pixel is expanded to the adjacent pixels by interpolation operation, so that the whole image is filled, But this will reduce the original definition and color.
.
.
at present, there are mainly 800 LCD TVs × 600、1280 × 768 and 1366 × 768 and other common resolutions.
.
.
10, screen refresh frequency.
10
for LCD display,
the high or low refresh rate will not make the picture flicker.
when the refresh rate is 60Hz,
LCD can get a good picture.
in LCD display,
each pixel will continue to emit light until the signal that does not emit light is sent to the controller, so the LCD display will not flicker due to continuous charging and discharging.
.
11 The service life is no less than 50000 hours.
.
.
.
some low-cost LCD TVs also have short service life.
therefore, special attention should be paid.
the service life of backlight is the service life of LCD TVs.
generally, the service life of backlight of LCD TVs is more than 50000 hours.
in other words,
if you use LCD TVs for an average of 5 hours a day, That 50000 hours of life is equivalent to 27 years of using the LCD TV.
