Q:The tube above the LCD has a sound
What brand of display? A little sound is not normal. It may be the sound of high voltage board discharge. It is recommended that you turn off the monitor, remove the power line, turn on the rear lid of the display, and check the wiring.
Q:How long is the normal service life of LCD?
The LCD panel itself does not emit light; it belongs to the backlight type display device. Behind the LCD screen, there is a backlight, LCD TV is to rely on the LCD panel on the panel "block" and "open" backlight lights, to restore the screen. It can be found that as soon as the LCD power is on, the backlight will start to work, even if the display is a full black picture, the backlight will remain in the same working state. Because the light transmittance of LCD panel is very low, the brightness of LCD TV should be reduced to the level of restore screen. The brightness of the backlight is at least 6000cd / m2. Backlight life is the life of LCD TVs, general LCD TV backlight life of more than 50 thousand hours. That is to say, if you use LCD TV on average 5 hours a day, the life of 50 thousand hours is equal to you can use the LCD TV for 27 years.
Q:What is the imaging principle of liquid crystal display?
1, liquid crystal display (LCD/Liquid Crystal Display) imaging principle, is to place liquid crystal between two conductive glass, driven by the electric field between the two electrodes, the liquid crystal molecules to distort the electric field effect of columns, in order to control the light transmission or shadowing function, the switch in power between the shade and image is displayed. If coupled with the color filter, it can display a color image.In 2, with two pieces of glass substrate alignment film, liquid crystal alignment along the groove so that the glass substrate with 90 degree deviation due to the film groove, so the liquid crystal molecules become reverse type, when the glass substrate without electric field, the light through the polarizer with LCD 90 degree twist, the lower polarizing plate, liquid crystal the display panel white; when the glass substrate is the electric field, the liquid crystal molecules to produce alignment changes, light through the liquid crystal molecular gap to maintain the original direction is below the polarizing plate shielding light is absorbed, not revealing, LCD panel display black. Liquid crystal display is based on this voltage, so that the panel to achieve the display effect.Basic introduction:A liquid crystal display (LCD) is a flat, ultra thin display device consisting of a certain number of color or black and white pixels, placed in front of the light source or reflector. Liquid crystal display power consumption is very low, so it is favored by engineers, applicable to the use of battery electronic equipment. Its main principle is to stimulate the liquid crystal molecules with electric current to produce dots, lines and planes, and match the back lamp tube to form a picture.
Q:A thin line of liquid crystal display screen
Obviously is the LCD screen drive, the wiring has bad contact. But this cable doesn't work well, so it needs special tools. Repair.
Q:LCD screen black, every time re inserted the power supply, and how can I do?
The display of data cable jack and host graphics card connection problem, or graphics card problem!
Q:Can the lens cleaning liquid clean the LCD?
The liquid crystal surface is a film, so you must make sure that the cleaning solution will corrode the plastic!
Q:What does ITO mean in an LCD LCD?
ITO is a N type oxide semiconductor - indium tin oxide, ITO film, indium tin oxide semiconductor transparent conductive film, usually has two performance indicators: resistivity and transmittance.
Q:LCD has a little blinking
1, there may be a video card problem2, there may be a problem with the monitorHow to detect:1, unplug the monitor and the VGA line that connects the video card to see if there is any signal on the monitor2, the general display problem, in the absence of signal, these words will appear in the picture of the kind of situation3, and the contrary is the graphics card problemThis situation, usually LCD display is still moreNo way to repair the defect but Lenovo has a bright dark standard 353That allowed 2 highlights two scotomaHighlights add up to not more than five yearsThe distance between the bright dark spots within a two point inside if too close can also change with the new display.
Q:Can the liquid crystal display of notebook computer be wiped directly with wet cloth?
In theory, there are special LCD screen, cleaning towel and other special tools, clean yourself, it is recommended to use cotton dipped in alcohol scrub.But if you don't pay attention, you can scrub it with wet towels that are often sold in supermarkets. That's what I do, and nothing wrong with it.
Q:What is the difference between LCD monitor and LCD monitor?
In fact, they are the same, just using the drive board is not the same! Understand? Are all display devices.
