The size of the TV panel is the size of the LCD panel, but in fact it can not be achieved because of the frame occlusion. So there's a minimum size, which is your maximum visual size.
The size of the TV panel is the size of the LCD panel, but in fact it can't be achieved due to the shielding of the frame.

What is the minimum diagonal size of LCD TV display?

therefore, there is a minimum size.
this is your maximum visual size.
LCD maintenance and repair      pcworld.com.cn  |  2005-04-13   09:17  |    More and more consumers are paying attention to the problem of how to maintain the LCD.
this reporter interviewed LG Electronics, a professional LCD manufacturer, and asked their engineers to provide us with some good suggestions.
this article is about how to maintain the LCD      With the increasing maturity of LCD technology and the gradual popularization of price, LCD began to stride into the field of ordinary consumption.
now.
many people's desktop displays have been upgraded, The number of liquid crystal displays in the market is rising rapidly.
therefore, how to maintain and maintain liquid crystal displays has been concerned by more and more consumers.
in this regard, the reporter interviewed LG Electronics, a professional manufacturer of liquid crystal displays, and asked their engineers to provide us with some good suggestions.
therefore, don't put the LCD in a wet place.
and don't let anything with moisture enter the LCD.
if you find that there is only fog on the screen surface before starting the machine.
gently wipe it with a soft cloth; If moisture has entered the LCD,You can turn off the display, turn the LCD back to the sun, or use a desk lamp to bake and evaporate the water in it.
but you should be careful not to turn the LCD screen to the sun.
that will cause the aging of components.
experts remind consumers.
international manufacturers such as LG pay great attention to after-sales service. If there is a serious moisture event, they should pay more attention to after-sales service, It's better for ordinary users to contact the local brand after-sales service provider and ask them for help.
because.
the more serious moisture will damage the components of LCD, and when users power on the LCD with higher humidity, it will cause the corrosion of the LCD electrode, causing permanent damage.
this paper analyzes the causes of the corrosion of the LCD electrode      In addition.
hair gel used in daily life and mosquito repellent frequently used in summer will also damage the liquid crystal molecules and even the whole display, resulting in the shortening of the life of the whole display. Therefore, the contact between the display and chemicals should be avoided as far as possible.
in addition, the liquid crystal molecules and even the whole display will be damaged      Expert suggestion 2: try to avoid overloading the LCD for a long time      First of all.
don't keep the LCD in a high brightness state for a long time.
the display mode of LCD is different from that of CRT.
it is easy to shorten the service life of LCD backlight when the screen is highlighted for a long time, Attention should be paid to turn off the LCD.
in addition.
in daily use, the brightness of the LCD can be adjusted properly.
these measures will greatly help to prolong the life of the LCD.
the LCD can be used in daily life      Secondly,
try to avoid displaying the same picture for a long time.
LCD will cause internal aging or burning out due to long-time work.
especially when the same picture is displayed for a long time.
because LCD works for a long time, it is easy to make some pixels overheat.
when the same picture is displayed for a long timeOnce the limit is exceeded, it will lead to permanent damage and can not be repaired.
this forms the commonly known "bad point"
because the pixels of LCD display are composed of liquid crystals.
therefore, when working at full load continuously for more than 96 hours, it will accelerate its aging, and even burn out in serious cases.
therefore, experts remind consumers.
if users have to work for a long time, It's better to let them have a rest intermittently, or change the content of the screen at different intervals; If you just leave for a while, you should start the screen saver, or turn the brightness of the display screen down, or turn it into a full white screen, which can not only delay the aging of the LCD screen, but also avoid hardware damage.
in this way, you can not only slow down the aging of the LCD screen, but also avoid hardware damage      Expert advice 3: reduce unnecessary touch or vibration      LCD screen is very fragile and delicate.
therefore, we should get rid of the bad habit of pointing at the screen with fingers.
because even a slight click may produce local bad points.
in serious cases, it may even form a black spot, which is easy to cause more bad points, This is an important reason why some users will find more and more bad points after using for a period of time.
there is another point to note.
the power consumption of LCD is relatively small, but the voltage of transformer behind LCD is still very high; Special attention should be paid to safety. Do not open the back cover of the monitor when it is electrified.
even after the power failure.
the retained instantaneous voltage is very high. The CFL transformer in the background lighting assembly still has a high voltage of about 1000V, so it is better not to touch it at will.
in this paper, the author introduces the design of the CFL transformer      Not only that.
the anti-collision ability of liquid crystal display is also relatively poor, even the latest products, the anti-collision ability is still far less than CRT display.
this is because liquid crystal display contains many precision glass elements and sensitive and delicate electrical elementsOnce the LCD screen, related components or circuits are damaged by strong impact.
when people move the LCD screen.
they often do not pay attention to grasp the screen to move, which may also damage the surface of the LCD screen.
therefore, experts strongly recommend that the oscillation of large impact force and the pressure exerted on the surface of the LCD screen should be avoided.
therefore, it is necessary to prevent the vibration of large impact force and the pressure exerted on the surface of the LCD screen      Expert suggestion 4: remove the dirt on the surface of LCD correctly      If any dirt is found on the surface of the LCD, it should be removed by using the correct method.
the media used should be soft and non fiber materials.
for example, absorbent cotton, lens paper or eyeglass cloth, which can be cleaned with water in general; However, if the cleaning effect can not be effectively achieved, the special cleaning products for liquid crystal sold on the market can be considered.
some experts specially pointed out that consumers should not use cleaning solutions containing ammonia, alcohol and inorganic salts for cleaning     At present, LCD manufacturing technology attaches great importance to the design of low radiation, anti reflective, anti glare, anti-static interference, environmental protection, etc.
therefore, the manufacturing process of each part has undergone multiple protective treatments, such as multilayer mirror treatment, or coating more special polymer polymers, etc.
these special chemicals are usually treated by some chemicals containing ammonia, ammonia, ammonia, etc Alcohol and inorganic salt chemicals damage the display.
as a result, the display slowly loses its true optical transmittance, or produces color distortion due to refraction, or reduces its anti-interference and anti-static effect, which is not only harmful to the eyes and affects the image quality, but also destroys the original protection function, and greatly reduces the color and safety, Consumers have to be cautious      Expert suggestion 5: when encountering problems, do not disassemble the LCD display      Because the LCD is too preciseIt's also very delicate, so it's not allowed to replace parts at will like ordinary CRT displays.
therefore.
no matter what problems it has, don't dismantle the LCD display by yourself, which is not DIY's "game" scope; Once you suspect that the LCD is not working properly, you must find a professional manufacturer to help solve the problem.
experts remind consumers again.
because the CFL AC in the LCD backlight lighting module may still have 1000V high voltage (although it is micro current) after a certain time of shutdown, even if there is no harm to human body, it can be used for LCD, If unprofessional personnel can't deal with it properly, it may cause new component failure, and in serious cases, it may cause the screen to permanently fail to work      The above are some important maintenance methods proposed by LG LCD engineers.
it can be seen from them.
LCD is indeed a very delicate high-end product, and its quality and performance require high manufacturing technology and process.
therefore.
ordinary users should choose some brands with high popularity at the beginning of purchase, In particular, LG has recently made a promise that LCD displays will not be damaged, that is, there are no bright spots or dark spots, and Philips has also launched the same LCD products.
because they not only have excellent technology.
but also have a large number of after-sales outlets nationwide, and the service is more professional and high-quality, so that users can buy more at ease and use more comfortably.
