Q:How to distinguish between LED and LCD
Actually called LCD, LED is in the LCD panel behind the use of LED light, the ordinary is the tube light
Q:How long is the normal service life of LCD?
Service life of LCD displayCompared with the radiation that CRT displays can not eradicate, LCD has inherent advantages, and it basically has no radiation at all. LCDs are ideal for workers who use computers for a long time. Although the liquid crystal display power consumption and no radiation, but the LCD screen life is quite short, only about 5 years, and in use, the brightness will gradually decrease. Compared with the liquid crystal display, CRT display life is generally up to 10 years long, and that the effect will not be too big.The comparison of LCD and CRT is shown belowReference: http://digi.163.com/04/0809/15/0TBT3JRC001618JK_6.html1. it is recommended to work under normal temperature / humidity conditions. High temperature / high humidity affects the life of liquid crystal displays.2., intense temperature fluctuations affect the performance of liquid crystal displays, especially low temperatures affecting brightness and response time.It is recommended to work in a smooth, clean environment where dust causes internal electrical circuits to fail.3., do not let the liquid splash into the display. If you need to clean, please turn off the power, spray the detergent on the soft cloth, and then wipe it gently.4. liquid crystal display is glass products, when moving, should avoid collision, vibration.5. liquid crystal display on the surface of multi-layer film, strictly prohibited with sharp instrument.6., forbid to disassemble the LCD at will, if the breakdown, must ask the professional personnel to maintain.7. fixed screen for a long time, will reduce brightness, image retention phenomenon increases, it is recommended to use screen saver.8. do not use for a long time, please turn off the power supply of the monitor and unplug the power plug.
Q:The LCD is black and bright
This is generally caused by the pressure plate or tube protection, certainly do not rule out the fault or power driven plate, pressure plate 150 for more than and 100 of the profits, sometimes encountered profiteers would not necessarily give you change, may just give you repaired.
Q:How many years can the AOC LCD monitor last?
LCDs can last 5 years!This is the general saying! Like television, the useful life is generally said to be 10 years, but my family's old Changhong TV, now almost 15 years, but also good!
Q:PHILPS 23 inch LCD is always black screen?
The display inside, a different host on the IC display MODE choice is not the same, when the old host MODE=1 (high), just use a CLK1 display, the new host MODE=0 (low), CLK1, CLK2, CLK3 display used to respectively control the three RGB transmission, as long as one of the CLK instability may flicker and when receiving an external interrupt signal may also affect the back of the two clock signal, resulting in black - IC display NG conclusion;
Q:The LCD suddenly became blurred
How about restoring the monitor to the factory?
Q:LCD and horizontal lines
The liquid crystal display is composed of a liquid crystal module, a drive circuit board and a shell, and the liquid crystal module is composed of a liquid crystal screen and a backlight, because the liquid crystal screen itself does not emit light and needs a light source to illuminate the screen. LCD screen is hardware, if there is a fault, disconnection, the phenomenon is irreversible, irreversible. The backlight is LED or CCFL light source, plus optical film material (make light walk more evenly) of the mechanical structure, closely attached to the back of the LCD screen.Is your problem, back light source on the optical film material due to aging, and the mechanical structure and the backlight module fit is not very strict, in the days when the heat deformation caused by thermal expansion and contraction, light out of the uneven distribution, resulting in the exterior looks like a white bar.If the fault needs to be repaired, it needs to get the dust-free workshop of the liquid crystal module factory, disassemble and replace the backlight, and the time and cost are relatively large.If you really affect vision, it is recommended that the landlord replace the monitor, the cost of maintenance is relatively large; if you have not seen the warranty period, find JS to replace the new monitor.Any further questions, please feel free to contact us
Q:I turn on the LCD monitor for ten minutes and then turn off automatically
Just look for a monitor. But I guess you should describe the monitor problem,! It is recommended to send the monitor to a professional repair shop
Q:LCD does not display images
Very simple, and resolution, refresh rate relationship. It is right that you suspect the difference. Turn on the machine and press F8 into VGA mode to adjust
Q:Do you need to erase the LCD?
There are two entirely opposite versions of the Internet: "degaussing" and "do not erase"! Personally think that does not require degaussing, reason is: liquid crystal display and CRT display principle are essentially different, will not cause adverse effect of remanence external magnetic field and the metal components of the display on the LCD color and color purity, so the liquid crystal display does not require degaussing circuit or degaussing.
