1、 What is LCD?
1、 What is LCD?LCD is liquid crystalThe full name of display is mainly TFT, ufb, TFD, STN and other types of LCD, which can't locate the program input point on the dynamic link library.

What is the difference between LED and LCD? Please make it easier to understand. I pay more attention to the clarity of the screen. The clearer the screen, the better,

in this paper, the dynamic link library is introducedTFT is commonly used in notebook LCD screen.
TFT (thin film transistor) refers to thin film transistor.
each LCD pixel is driven by thin film transistor integrated behind the pixel, so that it can display screen information with high speed, high brightness and high contrast. It is one of the best LCD color display devices at present, TFT is now the mainstream display device on laptops and desktops.
compared with STN.
TFT has excellent color saturation, reduction ability and higher contrast. It can still see clearly in the sun, but its disadvantage is that it consumes more power and costs more.
TFT has the advantages of high color saturation, reduction ability and higher contrast2、 What is led?LED is light emitting diodeLED applications can be divided into two categories: one is led display screen; the other is led display screen; The second is led single tube application.
including backlight LED, infrared LED, etc.
now as far as LED display is concerned.
China's design and production technology level is basically in line with the international level.
LED display is a 5000 yuan computer configuration sheet composed of LED arrays.
it adopts low-voltage scanning drive.
it has the following advantages: low power consumption, long service life, low cost, high brightness, high reliability, low cost, low cost, low cost, low cost, low cost, low cost, low cost, low cost, low cost, low cost, low cost, low cost, low cost, low cost, high brightness It has the characteristics of few faults, large viewing angle and long visual distance.
the system has the advantages of high reliability, low cost and low cost3、 The difference between LCD and ledCompared with LCD display, LED display is betterLED has more advantages in brightness, power consumption, viewing angle and refresh rate, and the navigation to the webpage has been cancelled.
LED technology can be used to produce thinner, brighter and clearer displays than LCD.
in this paper, the development of LED technology is introduced1. The power consumption ratio of LED and LCD is about 1:10.
LED is more energy-saving.
LED is more energy-saving2. LED has higher refresh rate.
it has better performance in video.
LED has higher refresh rate3. Led offers up to 160 ° It can display all kinds of text, digital, color image and animation information, and can play TV, video, VCD, DVD and other color video signals.
it can also display all kinds of text, digital, color image and animation information4. The single element reaction speed of LED screen is 1000 times faster than that of LCD screen.
it can be taken care of under strong light, and can adapt to the low temperature of minus 40 ℃To put it simply.
LCD and LED are two different display technologies. LCD is a display screen composed of liquid crystal, while LED is a display screen composed of light-emitting diodes.
LCD and LED are two different display technologiesDear friends,
now we should understand the difference between LCD and led! So you will say that led is so good, then I must buy LED display! However, the focus of this paper is also to come: at present, the LED display in the market is not the real sense of the LED display, to be exact, it is the LED backlight LCD, the LCD panel is still the traditional LCD display, in a sense, this more or less contains the nature of fraud! Samsung was once judged by the British advertising association to have violated the advertising law of the country because its "ledtv" LCD TV is suspected of misleading consumers.
for LCD, the most important key is its LCD panel and backlight type,However, TFT panel is generally used in the LCD panel on the market, which is the same. The only difference between LED and LCD is that their backlight types are different: LED backlight and CCFL backlight (i.e. fluorescent lamp), which are diode and cold cathode lamp respectively.
LED backlight and CCFL backlight (i.e. fluorescent lamp) are differentThe difference between LED display and LCD display: LED backlight: power saving (30% ~ 50% compared with CCFL).
high price, high brightness and saturationCCFL backlight: compared with LED backlight, CCFL backlight consumes a lot of power (much less than CRT).
it is cheaper.
CCFL backlightPicture difference: the color of LED backlight is bright.
the saturation is high (CCFL and led have different natural light sources).
the color of LED backlight is brightHow to distinguish: LED backlight will especially emphasize LED TV.
what is not emphasized is CCFL LCD TV.
in this case, we can refer to the following methods:1. Start the computer, go to the desktop, and right-click in the blank space to open the right-click menu on the desktop2. In the pop-up right-click menu.
select the attribute and click3. Then enter the window to display the attributes.
move the cursor to the right and select the tool menu for setting the attributes.
select the tool menu4. Find the screen resolution item under the settings toolbar.
the general screen resolution is 1024x7685. Press and hold the slider with the mouse.
adjust the resolution, set it to 800x600, and then press and hold the button firmly.
everyone's screen size is different.
according to the size of their own computer screen,To set the resolution.
but don't set the screen resolution too high.
otherwise, the screen will be black, which will be troublesome.
6. After setting the screen resolution.
go back to the desktop to see the size change of the desktop icon and whether the eraser is clear. If it's not appropriate, you need to adjust it again until you are satisfied.
