Kas LCD-ekraani heleduse määrab taustvalgustuse allikas:
As we all know, LCD displays present images through a special backlight source, and the performance of the backlight source also has an important impact on the brightness of the display, so the brightness of the LCD display depends only on the backlight source.
LCD ekraan
After the backlight emits light, the light is controlled by the voltage of the front LCD display panel, and the liquid crystal molecules allow the light to pass through or mask to display the brightness of the image. This process is controlled by an IC chip, which is similar in principle to a shutter in a camera and can control the luminous flux. Camera products are usually equipped with a shutter on the back of the lens, and the shutter is opened when shooting, allowing the object to be imaged in the film or photosensitive element to form a photo. In addition, the liquid crystal panel emits light with balanced brightness from a backlight, which is blocked/controlled by the light of the liquid crystal panel, and is imaged by the light and shadow of the light.
When you watch an image on an LCD monitor or LCD TV, you will find that the light passing through the LCD panel not only appears in the form of name and darkness, but also has various colors from light to dark. In addition, when we continuously watch an animation, the standard is that we need 60 pictures per second, that is, the light and dark state is switched 60 times per second. In order to display the pictures accurately, there must be enough pixels. The structure of the liquid crystal panel should also be fine enough. From this perspective, high-end LCD panels and low-end products will be different in this respect, which is also one of the reasons for the cost difference.
LCD monitors can use voltage to control light intensity at high speed, but since the LCD panel can only control light and shadow, this mechanism is only effective for black and white pictures. If you want to display a color picture, you also need to place a color filter in front of the liquid crystal molecule layer to add color to the bright light and dark light. Therefore, in addition to the brightness of the backlight itself, the control of the liquid crystal molecules by the IC chip (operation on/off), the quality of the liquid crystal panel itself, the aperture ratio and the light transmittance, etc., will all have a certain impact on the brightness of the liquid crystal display.
Ülaltoodud sisu on sissejuhatus selle kohta, kas LCD-ekraani heleduse määrab taustvalgustuse allikas. LCD-ekraan kiirgustab inimkeha väga vähe ning ekraan on pehme ega kahjusta silmi. See võib kaitsta meie nägemist. Keha on õhuke ja säästab. Võrreldes mahukama CRT-ekraaniga vajab LCD-ekraan ainult ühe{0}}kolmandiku esimesest. Samuti säästab see elektrit ega tekita kõrget temperatuuri. See on vähese võimsusega-toode. Kui vedelkristallekraani paneelil on tolmu, peate tegutsema professionaalse hoolduspersonali nõuannete kohaselt. Ärge leidke selle pühkimiseks lihtsalt kaltsu või karedat asja. Ebaõige kasutamine võib ekraani kahjustada ja kahjustada LCD-ekraani. .
